What Can Happen if Your Tires Are Going Bald

There are millions of cars on the road and millions of drivers, most of which know what to do to keep a car safe. Keeping parts like the steering rack and the steering gearbox in good shape is something everyone makes sure to check out but what about the small parts? Well not really the small parts but the tires…they are ignored waaaay too often when it comes to car repair.

Tires are the contact patch on the road and are the only way that a vehicle can move around. If any driver were to stop and look around a bit at the tires on other cars around them they may think twice about getting on the road. It can be seen that one in five cars has tires that are beyond what would be considered bald and one in ten is to the point where failure is a serious concern. When a tire is new the rubber is stiff and has good grip in the road, as a tire loses tread it beings to soften due to less rubber in the wheel. Softer tired walls mean slower reaction time. Slower reaction time can be the least of the worries with balding tires. While a bald spot on a man may be cause for a comb-over, on a tire it is a serious situation. The tread on a tire has been specifically designed to help grip the road just like the tread on a shoe.

When tires are bald the grip they can provide is compromised and the stopping power is also reduced. The tread is designed to take advantage of the friction between the spaces in the tread and when it is missing the tires are useless. Bald tires also run the risk of bursting due to the reduced amount of material on them. The Tires are extremely important and should never be over looked, so next time you head out to your car take a min to check out the tires. 

Speech interfaces: UI revolution or intelligent evolution?

Speech interfaces have received a lot of attention recently, especially with the marketing blitz for Siri, the new speech interface for the iPhone.

After watching some of the TV commercials you might conclude that you can simply talk to your phone as if it were your friend, and it will figure out what you want. For example, in one scenario the actor asks the phone, “Do I need a raincoat?”, and the phone responds with weather information.

A colleague commented that if he wanted weather information he would just ask for it. As in “What is the weather going to be like in Seattle?” or “Is it going to rain in Seattle?”.

Without more conversational context, if a friend were to ask me, “Do I need a raincoat?”, I would probably respond, “I don’t know, do you?” — jokingly, of course.

Evo or revo?

Are we ready to converse
with our phones and cars?

Kidding aside, systems like Siri raise an important question: Are we about to see a paradigm shift in user interfaces?

Possibly. But I think it will be more of a UI evolution than a UI revolution. In other words, speech interfaces will play a bigger role in UI designs, but that doesn't mean you're about to start talking to your phone — or any other device — as if it’s your best friend.

Currently, speech interfaces are underutilized. The reasons for this aren't yet clear, though they seem to encompass both technical and user issues. Traditionally, speech recognition accuracy rates have been less than perfect. Poor user interface design (for instance, reprompting strategies) has contributed to the overall problem and to increased user frustration.

Also, people simply aren't used to speech interfaces. For example, many phones support voice-dialing, yet most people don't use this feature. And user interface designers seem reluctant to leverage speech interfaces, possibly because of the additional cost and complexity, lack of awareness, or some other reason.


"Relying heavily on speech can lead
to a suboptimal user experience..."
As a further complication, relying heavily on speech as an interface can lead to a suboptimal user experience. Speech interfaces pose some real challenges, including recognition accuracy rates, natural language understanding, error recovery dialogs, UI design, and testing. They aren't the flawless wonders that some marketers would lead you to believe.

Still, I believe there is a happy medium for leveraging speech interfaces as part of a multi-modal interface — one that uses speech as an interface where it makes sense. Some tasks are better suited for a speech interface, while others are not. For example, speech provides an ideal way to provide input to an application when you can capitalize on information stored in the user’s head. But it’s much less successful when dealing with large lists of unfamiliar items.

Talkin' to your ride
Other factors, besides Apple, are driving the growing role of speech interfaces — particularly in automotive. Speech interfaces can, for example, help address the issue of driver distraction. They allow drivers to keep their “eyes on the road and hands on the wheel,” to quote an oft-used phrase.

So, will we see a paradigm shift towards speech interfaces? It's unlikely. I'm hoping, though, that we'll see a UI evolution that makes better use of them.

Think of it more as a paradigm nudge than a paradigm shift.

What is a Knock Sensor

The knock sensor is the unit in the car that protects against incorrect timing issues. It allows the engine to run with the timing advanced as far as possible without damaging the motor or loss of power. Unlike oxygen sensors or the air fuel ratio sensor the knock sensor will not allow the car to run incorrectly. A knock sensor feed info to the ECU and if the car is knocking too much to be adjusted by timing to will send the ECU into a safe mode which will stop the engine all together.

The knock sensor works by responding the knock caused by pre-detonation of the air/fuel mixture. When the fuel mixture in a cylinder is ignited there is a flame front that moves out from the source of the spark. When this pressure wave hits the cylinder walls it makes a noise and this is detected by the Piezoelectric element in the sensor and communicated to the ECU.

When the ECU detects these that are not at the correct time it triggers an adjustment in the motors timing. If the knock sensor fails it can cause the vehicle to run very rough or not start at all. When failure occurs a trouble code is triggered which may show as the sensor or as something else in the motor. A huge factor to remember with ECU codes is that they only show the source of the code, not the issue. In other words the code may be caused by a loose wire but it says knock sensor, it is important to remember this when diagnosing an issue. 

Enabling the next generation of cool

Capturing QNX presence in automotive can’t be done IMHO without a nod to our experience in other markets. Take, for example, the extreme reliability required for the International Space Station and the Space Shuttle. This is the selfsame reliability that automakers rely on when building digital instrument clusters that cannot fail. Same goes for the impressive graphics on the BlackBerry Playbook. As a result, Tier1s and OEMs can now bring consumer-level functionality into the vehicle.

Multicore is another example. The automotive market is just starting to take note while QNX has been enabling multi-processing for more than 25 years.

So I figure that keeping our hand in other industries means we actually have more to offer than other vendors who specialize.

I tried to capture this in a short video. It had to be done overnight so it’s a bit of a throw-away but (of course) I'd like to think it works. :-)

QNX and Freescale talk future of in-car infotainment

Paul Leroux

QNX and Freescale enjoy one of the longest technology partnerships in the field of automotive infotainment. The roots of their relationship reach back to 1999, when QNX became a founding member of MobileGT, an industry alliance formed by Motorola (Freescale's parent company) to drive the development of infotainment systems.

If you've read any of my blog posts on the QNX concept car (see here, here, and here), you've seen an example of how mixing QNX and Freescale technologies can yield some very cool results.

So it's no surprise that when Jennifer Hesse of Embedded Computing Design wanted to publish an article on the challenges of in-car infotainment, she approached both companies. The resulting interview, which features Andy Gryc of QNX and Paul Sykes of Freescale, runs the gamut — from mobile-device integration and multicore processors to graphical user interfaces and upgradeable architectures. You can read it here.
 

What Causes an Engine Fire and What Should Be Done

Car and trucks move by harnessing the power of fire, the combustion in the motor is a controlled explosion that moves the pistons. Inside the motor the fuel injectors and fuel pump work together to add the correct amount of fuel to complete the combustion process. Any form of combustion is going to create heat that will need to be dispersed but there are lots of heat sources in an engine besides the motor. 

The systems that run the motor all create heat through movement and electricity. When the heat in an engine bay gets to be too much for the coolant system to handle it is just a matter of time before one of the elements in the system reaches the point of fire. When the coolant begins to slow its movement due to a weak pump or a blockage in the system it becomes a very dangerous thing. Not only will the coolant begin to expand very quickly but it also reaches its flash point, which means the temp is so high that if it touches air it will ignite. This is the first source of engine fire which can usually be seen by what seems to be liquid fire dripping under the car. The coolant over flows and starts to catch fire, this can be caught early and stopped. 

The second main cause of engine fire is when wiring has become exposed and the spark created by the open loop creates enough heat to catch the wire on fire. Electrical fire will have no signs before-hand so they can be devastating to the vehicle.

In the event of a vehicle fire do not try and extinguish the flames without proper equipment. Many times the fuel in the car can ignite and that will cause a very large flame which can be dangerous. If an engine fire is suspected do not open the hood, the fire may be contained and not getting enough air but once that hood is opened the flow of air will cause a very large explosion. If an engine fire is suspected touch the hood with the back of your hand in the same fashion that is used to check for fire on the other side of a door in a building.  If the paint on the hood has begun to bubble it is a tell-tale sign of an engine fire. The best use of a driver’s time when an engine fire occurs is to get everything of value out of the car and then get some distance. Engine fires are no laughing matter and they should be handles by the fire department. Even though losing your car due to fire can really suck it is better than losing your life.

When will I get apps in my car?

I read the other day that Samsung’s TV application store has surpassed 10 million app downloads. That got me thinking: When will the 10 millionth app download occur in the auto industry as a whole? (Let’s not even consider 10 million apps for a single automaker.)

There’s been much talk about the car as the fourth screen in a person’s connected life, behind the TV, computer, and smartphone. The car rates so high because of the large amount of time people spend in it. While driving to work, you may want to listen to your personal flavor of news, listen to critical email through a safe, text-to-speech email reader, or get up to speed on your daily schedule. When returning home, you likely want to unwind by tapping into your favorite online music service. Given the current norm of using apps to access online content (even if the apps are a thin disguise for a web browser), this begs the question — when can I get apps in my car?

Entune takes a hands-free
approach to accessing apps.

A few automotive examples exist today, such as GM MyLink, Ford Sync, and Toyota Entune. But app deployment to vehicles is still in its infancy. What conditions, then, must exist for apps to flourish in cars? A few stand out:

Cars need to be upgradeable to accept new applications — This is a no-brainer. However, recognizing that the lifespan of a car is 10+ years, it would seem that a thin client application strategy is appropriate.

Established rules and best practices to reduce driver distraction — These must be made available to, and understood by, the development community. Remember that people drive cars at high speeds and cannot fiddle with unintuitive, hard-to-manipulate controls. Apps that consumers can use while driving will become the most popular. Apps that can be used only when the car is stopped will hold little appeal.

A large, unfragmented platform to attract a development community — Developers are more willing to create apps for a platform when they don't have to create multiple variants. That's why Apple maintains a consistent development environment and Google/Android tries to prevent fragmentation. Problem is, fragmentation could occur almost overnight in the automotive industry — imagine 10 different automakers with 10 different brands, each wanting a branded experience. To combat this, a common set of technologies for connected automotive application development (think web technologies) is essential. Current efforts to bring applications into cars all rely on proprietary SDKs, ensuring fragmentation.

Other barriers undoubtedly exist, but these are the most obvious.

By the way, don’t ask me for my prediction of when the 10 millionth app will ship in auto. There’s lots of work to be done first.

 

Marking over 5 years of putting HTML in production cars

Think back to when you realized the Internet was reaching beyond the desktop. Or better yet, when you realized it would touch every facet of your life. If you haven’t had that second revelation yet, perhaps you should read my post about the Twittering toilet.

For me, the realization occurred 11 years ago, when I signed up with QNX Software Systems. QNX was already connecting devices to the web, using technology that was light years ahead of anything else on the market. For instance, in the late 90s, QNX engineers created the “QNX 1.44M Floppy,” a self-booting promotional diskette that showcased how the QNX OS could deliver a complete web experience in a tiny footprint. It was an enormous hit, with more than 1 million downloads.

Embedding the web,
dot com style:
The QNX-powered Audrey

Also ahead of its time was the concept of a tablet computer that provided full web access. When I started at QNX, I was responsible for tablets, thin clients, and set-top boxes. The most successful of these pioneering devices was the 3COM Audrey kitchen tablet. It could send and receive email, browse the web, and sync to portable devices — incredibly sophisticated for the year 2000.

At the time, Don Fotsch, one of Audrey’s creators, coined the term “Internet Snacking” to describe the device’s browsing environment. The dot com crash in 2001 cut Audrey’s life short, but QNX maintained its focus on enabling a rich Internet experience in embedded devices, particularly those within the car.

The point of these stories is simple: Embedding the web is part of the QNX DNA. At one point, we even had multiple browser engines in production vehicles, including the Access Netfront engine, the QNX Voyager engine, and the OpenWave WAP Browser. In fact, we have had cars on the road with Web technologies since model year 2006.

With that pedigree in enabling HTML in automotive, we continue to push the envelope. We already enable unlimited web access with full browsers in BMW and other vehicles, but HTML in automotive is changing from a pure browsing experience to a full user experience encompassing applications and HMIs. With HTML5, this experience extends even to speech recognition, AV entertainment, rich animations, and full application environments — Angry Birds anyone?

People often now talk about “App Snacking,” but in the next phase of HTML 5 in the car, it will be "What’s for dinner?”!

 

Get Prior Auto Inspection to Get Suitable Used Cars For You

Buying a new car is always a planned decision where you invest a lot of your savings. No buyer would want that the used car they but comes out to be faulty and becomes trash after some days. Used car sellers have various tactics to lure the customers and make them believe that the car is perfect. They hide and adjust all kinds of faults so that the buyer does not notice them. Even at the time of the test drive the buyer is not able to look for any mistakes and thinks that the car is in perfect condition. They happily buy the car only to find out that the car is no more than a junk but majority of its parts requiring repairs.

Despite these facts used car buying still remains and is increasingly gaining popularity among the people around the world because of their affordability. But sometimes even the lure of saving some money can end up costing you more than what you earlier estimated. You don’t have to be an expert before buying a used car instead it is better to take an auto inspection services. Car check services hold an important place before you decide to buy a specific car as the actual condition of the car can be quite different from what is displayed. Professions from the car check companies can look for details that other people and even you will be able to look for. They can test and analyse the actual condition of the car and can help you get a clear picture about the actual condition of the car and how much it should ideally be worth of.

You can decide upon the details and can make sure that whatever you are buying and are investing your hard earned money in, is in good condition. Auto check includes various steps to correctly ascertain the condition of the car. During the auto inspection various parts are opened and worked in different intensities to find out how able the auto parts are. The professional who conducts the auto check are experts and even take the car out for a test drive apart from looking for minor faults.

An Introduction to Tire Pressure Monitoring Systems

Since 2006 most car have been fitted with a TPMS or tire pressure monitor system to check for issues with the tires. The basic idea behind the TPS system is that the tires pressure can effect the movement of the car. Just like an oxygen sensor or air fuel ratio sensor the TPMS sensors are crucial to the proper operation of the car.

While the tire pressure may seem like a trivial element but when the facts are examined it become a lot more interesting. Tires that are 10% low on air will result in a 1% decrease in gas mileage which can start to show in your wallet later on.

The main issue with the TPMS systems is that the sensors in the wheels are all battery powered which means over time they all have a failure rate of 100%. When the TPMS systems fail they will turn on a light on the dash which will alert the drive and also cause the vehicle to fail a state inspection. The good thing about these parts is that they are cheap and can be replaced when a set of tires is installed on any vehicle. Each one of the the sensors relays info to the central computer and will be standard equipment on all civilian vehicles from 2012 on.

BBDevCon — Apps on BlackBerry couldn't be better

Unfortunately I joined the BBDevCon live broadcast a little too late to capture some of the absolutely amazing TAT Cascades video. RIM announced that TAT will be fully supported as a new HMI framework on BBX (yes, the new name of QNX OS for PlayBook and phones has been officially announced now). The video was mesmerizing — a picture album with slightly folded pictures falling down in an array, shaded and lit, with tags flying in from the side. It looked absolutely amazing, and it was created with simple code that configured the TAT framework "list" class with some standard properties. And there was another very cool TAT demo that showed an email filter with an active touch mesh, letting you filter your email in a very visual way. Super cool looking.

HTML5 support is huge, too — RIM has had WebWorks and Torch for a while, but their importance continues to grow. HTML5 apps provide the way to unify older BB devices and any of the new BBX-based PlayBooks and phones. That's a beautiful tie-in to automotive, where we're building our next generation QNX CAR software using HTML5. The same apps running on desktops, phones, tablets, and cars? And on every mobile device, not just one flavor like iOS or Android? Sounds like the winning technology to me.

Finally, they talked about the success of App World. There were some really nice facts to constrast with the negative press RIM has received on "apps". First some interesting comparisons: 1% of Apple developers made more than $1000, but 13% of BlackBerry developers made more than $100,000. Whoa. And that App World generates the 2nd most amount of money — more than Android. Also very interesting!

I can't do better than the presenters, so I'll finish up with some pics for the rest of the stats...

New release of QNX acoustic processing suite means less noise, less tuning for hands-free systems

Paul Leroux

This just in: QNX has released version 2.0 of its acoustic processing suite, a modular software library designed to maximize the quality and clarity of automotive hands-free systems.

The suite, used by 18 automakers on over 100 vehicle platforms, provides modules for both the receive side and the send side of hands-free calls. The modules include acoustic echo cancellation, noise reduction, wind blocking, dynamic parametric equalization, bandwidth extension, high frequency encoding, and many others. Together, they enable high-quality voice communication, even in a noisy automotive interior.

Highlights of version 2.0 include:

Enhanced noise reduction — Minimizes audio distortions and significantly improves call clarity. Can also reconstruct speech masked by low-frequency road and engine noise.

Automatic delay calculation and compensation — Eliminates almost all product tuning, enabling automakers to save significant deployment time and expense.

Off-Axis noise rejection — Rejects sound not directly in front of a microphone or speaker, allowing dual-microphone solutions to hone in on the person speaking for greater intelligibility.

To read the press release, click here. To learn more about the acoustic processing suite, visit the QNX website.


The QNX Aviage Acoustic Processing Suite can run on the general purpose processor,
saving the cost of a DSP.

 

Wanted: Haunted Vehicles

Halloween is just around the corner, and that reminds me of the haunted room at Lucent Bell Labs. Mind you, it wasn’t really haunted. But for a moment, I was convinced.

Let me explain. As I entered the room, I could hear two of my colleagues talking to each other, and by the sound of their voices, they were both sitting right in front of me. But when I looked, I could see only one person. Creepy, to say the least.

It took a few seconds, but I finally realized what was happening: The other colleague was in a different room, talking over a perfectly tuned prototype of a conference phone. The sense of presence was so real that I couldn’t help but feel we were all in the same room — even after I became aware of the “trick” being played!

It was then that I realized it: We don’t know what we’re missing until we experience it.

Making it real
Current telephone calls don’t sound like face-to-face conversations because the telephone network and terminals band-limit speech from about 50-10000 Hz down to 300-3400 Hz. To make matters worse, the phone’s single channel of audio eliminates spatial information about the sound source. As a result, we perceive most sounds as coming from the same point in space.

But here's the thing: The historical reasons for transmitting these single-channel narrowband speech signals no longer apply. Current technologies — such as wideband speech coders, spatial audio, and VoIP — are enabling speech communications with wider bandwidth speech and greater spatial information.

Many in the industry refer to these next-generation telecommunications systems as telepresence systems. “Telepresence” refers to the degree of realism created by a telecommunications system. Traditional systems have low telepresence while newer systems that use wider bandwidth speech and spatial audio have high telepresence.

Some people believe that a visual display is a must-have for a telepresence system. In reality, a display can decrease telepresence if its quality is poor. Experience shows that an audio-only system can have such high telepresence that people can't distinguish it from face-to-face communications — witness my haunting experience at Lucent Bell Labs.

Until recently, widespread deployment of telepresence systems has hit a roadblock: lack of standardization. Fortunately, the IETF CLUE Working Group and ITU-T Study Groups 16 and 12 are actively developing standards to remedy this situation.

Pimp my ride with telepresence
Telepresence systems have a lot to offer in an automotive environment. For instance, they could:

• reduce driver distraction
• make it easier to understand speech in the presence of vehicle noise
• reduce the fatigue that comes from trying to understand a degraded voice signal

Moreover, a telepresence system makes the talker on the far end of the phone connection sound more like they are in the vehicle; it also makes the talker easier to identify.

Successful deployment of telepresence in an automotive environment depends on several factors:

• attention to the design of vehicle platforms
• use of high-performance acoustic processing algorithms (AEC, NR, etc.), such as those provided by the QNX acoustic processing suite
• the ability to transport telepresence signals between telephony terminals — this is being enabled by increased VoIP availability (via LTE, for instance)

I don't know about you, but I'm looking forward to the day when my vehicle is haunted like that lab in New Jersey!

Star Trek Art Car - from Greece?

Here is one of the first Star Trek art cars I have ever seen out of Greece and I commend him for doing it. It's the first art car period that I have ever seen out of Greece and having lived there my self, I can't imagine anyone driving around in them, yet. It will take sometime before its more accepted, but someone had to be the first. To you my bold friend I say, Yiassoo.

Tight Steering After a Rack Install

Recently the vehicle you drive had a leaking steering rack and it is leaving puddles everywhere you go. You think to your self "great! how much is this gonna cost?" so you find the power rack or power gearbox that you need online for a good price. The install goes well and the mechanic stands behind his work but the car is really hard to turn.  This must mean the part is bad...it is the only new part to the car and the old one turned fine.

After all this time and money the mechanic is telling you that the rack you ordered is bad and he will not warranty the labor cost. So now it is time call and scream at the company who sold the rack. But hold on...is there really issue tor more did the new rack that has exposed a preexisting issue. Many times an old power steering rack is loose and very easy to move, this means very little force is needed from the power steering pump. When the old worn out pump is now coupled with the new rack means that it may not make enough pressure to turn the rack. A tight rack can seem like a binding rack but it will never bind in both directions. An easy way to check for a failing pump is to rev up the motor and see if the car turns easier...if it does, you have a bad pump.

Mechanics don't care about diagnosing the issue most of the time if you bring your own parts but they are happy to charge labor again and again. Be sure that the company who is installing the part knows what they are doing and that they are good people. Every company can smile at you and act like a friend...walk onto a used car lot and you will have a new best friend till you buy a car but its all an act. Make sure the repairs to the steering system are done by a trust worthy company that can determine real issues for you.

Sausalito Art Car Gets New Life by Heather Wilcoxon

Heather Wilcoxon is better known as an artist from Sausalito Cailfornia who now lives on a decorated house boat called the "Delta Queen". I was honored to meet Heather last Saturday who came to my garage sale while visiting here sister who happens to live down the street from my house. We started talking about art cars and told me about her Gremlin art car that no longer works but has taken a whole new life as permanent garden art car in Sausalito CA. Its completely covered in toys and dolls and plants that have almost engulfed this amazing art car. For those of us with aging art cars on their last leg, this could be the next evolutionary step in the life of these wonderful works of art. More about Heather here

Harman infotainment systems gear up with QNX technology

Paul Leroux

If you've ever driven an Audi, BMW, Ferrari, Mercedes, or Porsche, chances are it used a sound system or infotainment unit from Harman International.

Mind you, Harman isn't just about the high end. They also offer a scalable infotainment platform that can target both higher-end and lower-end vehicles. And they aren't just about European cars, either. Earlier this year, they became the first non-Japanese supplier to supply an infotainment system (the QNX-based Entune system) to Toyota. They also supply systems to Hyundai, Lexus, Subaru, and Ssangyong.

Since 2003, Harman has used the QNX OS as the software platform for its infotainment products. (In fact, Harman owned QNX Software Systems for about 5 years, before QNX became a subsidiary of RIM.) In this video, Rick Kreifeldt, Harman's VP of global automotive research and innovation, discusses how QNX technology and expertise help Harman cut time-to-market and create greener products.

The Fin Car by Bill Lockner

the fin car

Bill Lockner’s car is a 1979 Volvo that has been enhanced and rebuilt using scrap yard metal, and car parts that were bound for the landfill. “It started out stock,” Lockner explains, “and as time went by, things got added to it.” These things include truck fenders, the back end of a Rambler, and a fin. “[The Fin Car] was an idea to use up and change a car that to me represented soccer moms in the ‘70s,” Lockner says. “Every soccer mom had a ‘79 Volvo.” Lockner’s car features a removable fin, naturally, and is fully operational. He has driven his car to art car festivals throughout Washington, and regularly services his car to keep it running for everyday use. “What I like about it is that it makes me laugh,” Lockner says. “Wherever I go, when I drive it, it makes me laugh.” Lockner has owned five or six art cars over the years, and currently has another that’s a work in progress. His newest car project is a 1975 Gremlin that Lockner hopes to turn into a kinetic sculpture.

Honda Accord Steering Moan Fix

In 2003 Honda introduced the new Accord with classically elegant lines and a few new upgrades to the interior. A new power steering rack and power steering pump were just a few of the updates. The car was a sales success selling hundreds of thousands of units but with great success comes great responsibility. When the accord begun to develop a steering moan on cold starts Honda was scrambling to find a solution that would not break the bank.

The solution came in the form of a 30 cent O-ring and about 15 minutes worth of work. The fix is simple and as elegant as the car itself. What causes the moan is air that has slipped into the system while cold and it creates bubbles or foam in the steering reservoir which will cause the pump to moan due to the added stress. The noise tends to go away once the fluid has warmed up but still the response "it's just noise" was not good enough for owners.

The process for fixing the issue is simple and will be covered in most cases by the deals but the owner must ask for consideration before beginning of the install. When the repair is performed the first step is to remove the inlet joint bolt and place a shop towel under it to catch leaks. Twist the inlet joint back and forth until loose and carefully disconnect the joint. Point the tube upward and remove the old inlet joint O-ring. Now apply power steering fluid to the new O-ring and with the new O-ring in place re-install the inlet joint. torque the bolt to 8ft-lbs and top off the power steering fluid as needed.

With this simple 15 minute install the moan will stop and no longer be problem, in the case that the noise continues check the levels of the steering fluid. The system may need to be bled to remove excess air that may have entered the system. If all the air is bled out and the system still moans you may actually have a failing steering pump and it is time for a more major repair.

QNX Auto Summit Japan 2011

How many car guys does it take to change a light bulb?  Three normally, but only one if you've already lifted  the engine block out of the way!

There's an actual reason for this joke which I'll explain in the epilogue.  But let me shamelessly segue: there's a whole room full of car folks here in Nagoya, and they're working on something which needs a good more heavy lifting than needed to change that troublesome light bulb.  They're building tomorrow's car systems.  To help, QNX is hosting a full day event here in beautiful Nagoya, covering what the latest goings on are in the automotive space that's near and dear to our hearts--in-cab vehicle electronics.

Getting seated before the day begins

Our first presenter was Dr. Motoyuki Akamatsu, who broke the ice with a very entertaining video about an early 1966 study on driver distraction.  The driver is wearing a device that looks like a giant eyelid that closes over his face on regular intervals, occluding his vision.  The driver is coincidentally also the narrator, calmly describing the whole experiment as his view of the road is completely blocked every couple seconds or so.  This is all while normal traffic is flowing around his car, totally unaware that this test driver could run into them at any moment. What they got away with in the sixties! The rest of his talk was equally informative; Akamatsu-san talked about how modern testing for driver distraction is done, and how mobiles can impact that.

I gave a talk about picking the right HMI (or UX if you prefer) framework for automotive infotainment.  There's a ton of choice out there--HTML5, Adobe AIR, Qt, Android, Meego, EB Guide,  OpenGL ES--I could go on and on. There are a lot of things to consider.  Given that I didn't have an abundance of time and that it was all being dynamically translated into Japanese, I couldn't cover as much as I might have wanted.  Look for a future blog from me where I can give the topic a little bit more space.  (Mini-spoiler alert: I've listed my favorite first.)

The president of ARM Japan gave a talk about ARM use in vehicles. A short summary: ARM processors are on the rise everywhere in the car, and trending upwards. ARM licensed 6 billion CPUs last year, and they predict 100 billion devices by 2020.  Japan is probably the only area where they aren't dominating (yet). A short roadmap then was presented about Cortex family--A8, A9, A15, and A5. Also he talked about the ARM M series. I must apologize that my jet lag affect my attention span during ARM M series (that architecture is almost irrelevant in infotainment, if that's an excuse). He also talked about ARM's Mali GPU built on Midgard architecture (supporting both OpenGLES 2.0 and DirectX9). 

Alex Kinsella of RIM gave a talk about separation of personal and enterprise use of devices, in a way that gives simultaneously more freedom for the user and more options and security for the enterprise.  All very cool stuff for enabling more OEM options to the vehicle.

Our very own Andrew Poliak talked about the various different connectivity options between cars and mobiles--both where we are today (MirrorLink, iPod Out, Remote Skin/BlueTooth SPP+A2DP) and where we see that they're going (HTML5, HDMI/MDL, USB 3.0).

Andrew explains OEM's evolving needs and timelines

Roger Lanctot of Strategy Analytics had a lot of interesting things to share about their in-depth research, covering current industry trends and some of Roger's predictions.

• Global smartphones are right now 38% of the mobile market, with all signs of growth.
• You need good traffic info that's predictive.  If it's not, its worthless, and navigation and traffic services are still the biggest customer desire out of an in-car system.
• Solve distraction problems before they are regulated out by governments.
• Apps in the car will be very important.  Their research shows over 55% buyers (world wide average) want it.  OEMs though take note--this will sell cars, but there's no profit in it for the OEM themselves.
• Many different connectivity options exist. Nobody has hmi nailed yet, so there's a big opportunity to get it right.
• HMI solutions are converging on mobile device communications.

Roger lists every mobile connectivity solution known to man

Probably most emphasized facts of Roger's presentation were about China.

• China is important. If you don't play there you're writing your own ticket for irrelevance. It's the fastest growing automotive market, with a rich aftermarket space.
• China infotainment solutions are like the wild west right now, and include some crazy displays that Roger showed us with dozens of touch buttons.  They've even got systems that have the ability to create and edit docs while driving! Microsoft Word at 70mph, here I come!  I can't wait for the next IDE to have in-vehicle recognition so I can program while driving.  
• China has exceedingly complex HMIs with apparent disregard for any regulations that might exist. 
• China is not the safest place.  They've got tons of new drivers, new infrastructure, and growth rates that exceed their experience.  The World Health Organization estimates 200,000 vehicle fatalities (significantly higher than China's officially reported numbers).  That's around 18% the world total vehicular fatalities.  Wow.

Finally, our VP of Sales and Marketing Derek Kuhn ended up with a description of where QNX is going for the future automotive platforms with QNX CAR 2.  In a word?  Awesomeness.  (Coincidentally, this is Derek's favourite word.) In ten? Full support for almost everything car makers ever dreamed of. 

We wrapped up the day with a cocktail hour for all our guests and some Formula 1 race day ticket give-aways to some lucky attendees.  

Guests having caught their taxis or trains, and the show nicely wrapped, the QNX staff gave secret surprise birthday wishes to our Alison Canavan, the world's best event coordinator, and to the world's most thoughtful person and our Auto Summit Japan emcee, Kosuke Abe.

All in all, a very busy and successful day.  I'm pooped.  And that's a wrap.

You've probably forgotten about the car guy lightbulb joke already, but I'll finish explaining it anyway. My girlfriend had one of her car's headlights burn out, and she asked me if I could fix it. My male chivalry and handyman pride made me jump at the opportunity to help! I naively went out to the car with a screwdriver, expecting to maybe loosen the screws around the light enclosure, pop out the bulb, put in the new one, and dust off my hands for a well deserved beer in one minute flat. It became immediately obvious that Honda had something much more nefarious in mind when they built the Civic. No screws.  You had to remove the bulb from the back, but there wasn't any obvious way for a human hand (well, no adult human, anyway) to fit in the allotted space.  I went back into the house, grabbed a handful of tools this time, and spent the next 20 minutes trying to figure out what parts of the car needed to be disassembled to get at the light bulb. This wasn't immediately fruitful either, so I went back in the house, consulted the Internet, and lo and behold--I wasn't just an idiot.  I found many other posts from many other delighted Civic owners.  It looked like the most popular solution was to remove the battery, battery cage and power steering pump mounts, lift the power steering out of the way, and then you could get at the bulb.  More of a challenge than I was really looking for, I'm afraid, so I went back to my girlfriend, tail between my legs, and shamefully recommended that she take it to the dealer.

I couldn't help smiling at her retelling of the dealer visit.  The first mechanic came out, all confident with a line something like "well, many guys don't really know how to do car stuff, so we'll take care of it."  Then he spent about 15 minutes digging around, trying to discover how on earth you get the stupid bulb out.  He finally had to call over his boss to get assistance.  They did end up replacing the bulb, but it was a little more complicated than he expected too! Tally it up--me and two mechanics--three guys to replace a light bulb. 

Good thing that building automotive software is so much easier.

QNX Auto Summit Japan 2011 – ‘Automotive at the speed of Mobility’

The QNX Auto Summit Japan 2011 will be starting soon, here in Nagoya, Japan.  We’re expecting a good crowd of Tier 1s and OEMs from across Japan.  QNX technology is being showcased in a BMW X5 and Audi A8 - as seen below - as well as in many of our partner demos.  The theme of the event is ‘Automotive at the speed of Mobility’!  Industry speakers will focus on how the worlds of automotive and mobility are converging at a break-neck speed, and what Tier 1s and OEMs will need to know to design for these next-generation systems.  Should be interesting!  Stay tuned for more.

What Makes a Car Cool

Cool is a word that can be used to describe many a thing...it can be a mass air flow sensor or alternator that is new and works in a  unique way. It can also be a car that may look ugly as hell but for some reason we all want one....WRX STI anyone. The fact that a car is bad wont even make it loose its cool factor...in fact it may even help.

The cool factor is something that auto makers have struggled with for year and even tried to force on people. The truth is if a car is cool it will be made that way by the general public, it cannot be told to you by the "car hipsters". People tend to fall into crowds of what everyone else likes but many of us like what we like because it is   "cool". This to me means that a car has the "it" factor, there is something about it that i like but i cannot tell you why. This is something that cannot be forced if it is not there. One of the best examples of a missing cool factor was the Pontiac Aztec which was billed as the car of the future and marketed to be the coolest new car. It failed....epically, not only was it one of the single ugliest cars ever made it was also trash in every way that can be compared to a car. On the other hand there are cars that are worthless that are cool like the Nissan 240SX. Not to say that it is not awesome but as a stock car it was a dud.  A small under powered truck motor sat under the hood and while the car looked sporty the suspension was set up for comfort not sport.

The 240 personifies this "cool factor" like the old school civic because they became something very different then they were intended. The cool factor developed from the cars being modified and after a while no one saw the car as just a car. They saw what it could be...and this is the essence of cool. It is the factor where a person sees a car and thinks what if can become which make it just ...plain cool. Of course there is always Aston Martin which is just the epitome and has been since its start.
