The QNX Sound Machine at CES

If you’ve ever had the pleasure of attending the Consumer Electronics Show, you’ll know that it’s a crowded place full of lights and noise. In the automotive North Hall, much of the cacophony comes from the legions of car customizers blasting bass from sedan-sized speakers. This year, QNX has brought a new kind of technology concept car to CES, based on a Kia Soul, that offers some subtler forms of sound artistry. (Sorry, hamster fans—I don’t think we’ll have your favorite mascot in the QNX booth.)


A sound ride: the new QNX technology concept car for acoustics

Let’s start with noise. Everyone likes a booming radio, sometimes. But if that’s the only tool you have to drown out engine noise you’ll go deaf. That’s where Active Noise Control (ANC) comes in. Think of ANC as a more sophisticated version of noise cancelling headphones that you don’t need to wear. Not only does ANC help keep the car’s cabin quiet, but the QNX solution is software based and doesn’t require a dedicated hardware module, saving the OEM and the consumer money.

The best part about ANC is that it helps cars become more fuel efficient. Huh? To keep car interiors quiet, automakers add baffling in the doors and under the floor to help mute engine noise. Dragging around that extra weight costs fuel. So removing the ballast (I mean baffles) lets the automakers make more fuel-efficient cars. And with ANC, which helps eliminate the extra noise caused by this approach, everyone wins.

Beyond wideband
Next up: a new level of call quality. If you’ve had the pleasure of conversing between two newer smartphones (BlackBerry Z10 or Z30, iPhone 5, Nokia Lumina 520, Samsung Galaxy S4, ...) you may have noticed that the call sounded better than what you’re used to. That’s because many newer phones support something called wideband audio (or HD Voice), which transmits more audible frequencies to make the call sound clearer. That’s good, but QNX wants to show what’s possible beyond wideband. So in the QNX technology concept car for acoustics, we’re demoing a new audio feature called full-band stereo calling, which is like having phone calls with CD quality audio. A full-band call has over six times the transmitted frequency range of a standard call, and more than double that of wideband. And as the name suggests, full-band stereo provides two independent channels, adding to the depth and sense of presence, making the call quality something that just has to be experienced.

Sound like a V8, sip like a Volt
Lastly — we get to pump up the volume! The technology concept car for acoustics also sports engine sound enhancement (ESE), which plays synthesized engine sounds over speakers inside the car. With ESE, your engine appears to sound a little more throaty. It may not be obvious, but this is also a fuel saving technology! As carmakers look for creative ways to turn gasoline slurpers into sippers, they’re implementing technologies that dynamically modify engine cylinder firing. Those changes can sometimes make a perfectly powerful engine sound anemic, which negatively impacts customer first impressions. Unfortunately, most people want a car that sounds and performs like it has a huge V8 even if they expect it to sip gas like a Chevy Volt. Both ANC and ESE can help the customer get over their performance anxiety. ESE also lets drivers get in tune with their engine, making it easier to shift by ear.

If you’re up for a little fun, you can also use ESE to make your car sound like something completely different. We’re playing the ESE audio outside the car as well as inside it. The Kia is using QNX ESE audio to masquerade as another car. Tweet us at @QNX_Auto if you can guess what it is!


The wraps are off! First look at the new QNX technology concept car

A quick tour of one of the vehicles that QNX is unveiling at 2014 CES

You know what? Writing this post isn’t easy. All I’ve got are words and pictures, and neither could ever do justice to the user experience offered by the new QNX technology concept car. They cannot, for example, recreate the rich, luminous sound of the car’s full-band and wide-band hands-free calls. Nor can they evoke how the car blends speech recognition with a touch interface and physical controls to make navigation, Internet radio, and other applications wonderfully easy to use.

But on second thought, words and pictures aren’t that bad. Especially when the car — and the in-dash systems that the QNX concept team created for it — are so downright gorgeous. So what are we sitting around for? Time for a tour!

Actually... hold that thought. I just want to mention that, if you visit our Flickr page, you can find full-resolution versions of most of the images I've posted here. Because why settle for low res? Okay, back to the tour.

The car
I've got two things to say here. First, the car is based on a Mercedes-Benz CLA45 AMG. If you guessed the model correctly based on the teaser images we published on the QNX website, I bow in homage to your eagle eye. Second, while we snapped this photo in the QNX garage, don’t think for a minute that the garage is ever this neat and tidy. On any given day, it’s chock full of drill presses, tool boxes, work tables, embedded boards, and QNX engineers joyously modding the world’s coolest cars — exactly the kind of place you expect it to be. And want it to be! But to humor the photographer, we (temporarily) made this corner clutter-free. We're nice that way.



The dash
Let's get behind the wheel, where you can see the car's custom-built digital instrument cluster and infotainment system. The bold design, the clean layout, the super-easy-to-access controls — they all add up to systems you want to interact with. Just as important, the look-and-feel of the instrument cluster and infotainment system are totally different from the corresponding systems in our previous concept car — an excellent illustration of how the QNX platform can help customers create their own branded experiences.



The multi-talented cluster
Time to zoom in on the digital instrument cluster, which helps simplify driving tasks and minimize distraction with an impressive array of features. Turn-by-turn directions pulled from the navigation system? Check. Video feed from front and rear-view cameras? Check. Notifications of incoming phone calls? Check. Alerts of incoming text messages, which you can listen to at the touch of a steering-wheel button? Check.



The Android app support
Automakers want to tap into the talents of the mobile app community, and the QNX CAR Platform for Infotainment helps them do just that, with built-in support for Android, OpenGL ES, and HTML5. In the concept car, for example, you'll find an Android Jellybean version of iHeartRadio, Clear Channel’s digital radio service, running in a secure application container. The QNX CAR Platform takes this same sandboxed approach to running HTML5 apps — perfect for protecting both the HMI and the overall system from unpredictable web content:



Helping you get there in more ways than one
We designed the QNX CAR Platform to give automotive developers the greatest possible choice and flexibility. And that’s exactly what you see when it comes to navigation. For instance, the car supports navigation from Elektrobit:



and from HERE:



and from Kotei Informatics:



If that’s not enough, a demo system in the QNX booth at CES also demonstrates a navigation system from Aisin AW — more on that in an upcoming post.

Pardon me while I barge in
As I alluded earlier, what you can't see in the new concept car is just as important as what you can see. For instance, if you look at this image, you'll see the infotainment system's media player. But what you can't see is new acoustics technology from QNX that lets you "barge in" and issue voice commands even when a song is playing. How cool is that?



When you find yourself in times of trouble...
... don't let it be, but rather, check and see. And to do that, you can use the infotainment system's virtual mechanic, which keeps tabs on your car's health, including fluid levels, brake wear, and, in this case, low tire pressure:



The cloud connection
Hold on, what's this? It looks like a smartphone app with an interface similar to that of the virtual mechanic, above. In fact, it's a lot more than that, and it touches on some cool (and very new) technology that can help cars become fully managed citizens of the cloud. More on that in an upcoming post.



That's it for now. For more details on what QNX is showcasing this week at CES, check out the press releases posted on the QNX website. And stay tuned to this channel for further updates from 2014 CES — including a profile of our very new QNX technology concept car for acoustics.
