Ontario tech companies team up to target the connected car

To predict who will play a role tomorrow's connected vehicles, you need to look beyond the usual suspects.

When someone says “automobile,” what’s the first word that comes to mind? Chances are, it isn’t Ontario. And yet Ontario — the Canadian province that is home to QNX headquarters — is a world-class hub of automotive R&D and manufacturing. Chrysler, Ford, General Motors, Honda, and Toyota all have plants here. As do 350 parts suppliers. In fact, Ontario produced 2.5 million vehicles in 2012 alone.

No question, Ontario has the smarts to build cars. But to fully appreciate what Ontario has to offer, you need to look beyond the usual suspects in the auto supply chain. Take QNX Software Systems, for example. Our roots are in industrial computing, but in the early 2000s we started to offer software technology and expertise to the world’s automakers and tier one suppliers. And now, a decade later, QNX offers the premier platform for in-car infotainment, with deployments in tens of millions of vehicles.

QNX Software Systems is not alone. Ontario is home to many other “non-automotive” technology companies that are playing, or are poised to play, a significant role in creating new automotive experiences. But just who are these companies? The Automotive Parts Manufacturers Association (APMA) of Canada would like you to know. Which is why they've joined forces with QNX and other partners to build the APMA Connected Vehicle.

A showcase for Ontario technology.
The purpose of the vehicle is simple: to showcase how Ontario companies can help create the next generation of connected cars. The vehicle is based on a Lexus RX350 — built in Ontario, of course — equipped with a custom-built infotainment system and digital instrument cluster built on QNX technology. Together, the QNX systems integrate more than a dozen technologies and services created in Ontario, including gesture recognition, biometric security, emergency vehicle notification, LED lighting, weather telematics, user interface design, smartphone charging, and cloud connectivity.

Okay, enough from me. Time to nuke some popcorn, dim the lights, and hit the Play button:

Some forward-thinking on looking backwards

The first rear-view camera appeared on a concept car in 1956. It's time to go mainstream.

Until today, I knew nothing about electrochromism — I didn’t even know the word existed! Mind you, I still don’t know that much. But I do know a little, so if you’re in the dark about this phenomenon, let me enlighten you: It’s what allows smart windows to dim automatically in response to bright light.

A full-on technical explanation of electrochromism could fill pages. But in a nutshell, electrochromic glass contains a substance, such as tungsten trioxide, that changes color when you apply a small jolt of electricity to it. Apply a jolt, and the glass goes dark; apply another jolt, and the glass becomes transparent again. Pretty cool, right?

Automakers must think so, because they use this technology to create rear-view and side-view mirrors that dim automatically to reduce glare — just the thing when the &*^%$! driver behind you flips on his high-beams. Using photo sensors, these mirrors measure incoming light; when it becomes too bright, the mirror applies the requisite electrical charge and, voilĂ , no more fried retinas. (I jest, but in reality, mirror glare can cause retinal blind spots that affect driver reaction time.)

So why am I blabbing about this? Because electrochromic technology highlights a century-old challenge: How do you see what — or who — is behind your car? And how do you do it even in harsh lighting conditions? It’s a hard problem to solve, and it’s been with us ever since Dorothy Levitt, a pioneer of motor racing, counseled women to “hold aloft” a handheld mirror “to see behind while driving.” That was in 1906.

For sure, we’ve made progress over the years. But we still fall back on kludges to compensate for the inherent shortcomings of placing a mirror meters away from the back of the vehicle. Consider, for example, the aftermarket wide-angle lenses that you can attach to your rear window — a viable solution for some vehicles, but not terribly useful if you are driving a pickup or fastback.

Small wonder that NHTSA has ruled that, as of May 2018, all vehicles under 10,000 pounds must ship with “rear visibility technology” that expands the driver’s field of view to include a 10x20-foot zone directly behind the vehicle. Every year, backover crashes in the US cause 210 fatalities and 15,000 injuries — many involving children. NHTSA believes that universal deployment of rear-view cameras, which “see” where rear-view mirrors cannot, will help reduce backover fatalities by about a third.

Buick is among the automotive brands that are “pre-complying” with the standard: every 2015 Buick model will ship with a rearview camera. Which, perhaps, is no surprise: the first Buick to sport a rearview camera was the Centurion concept car, which debuted in 1956:

1956 Buick Centurion: You can see the backup camera just above the center tail light.

The Centurion’s backup camera is one of many forward-looking concepts that automakers have demonstrated over the years. As I have discussed in previous posts, many of these ideas took decades to come to market, for the simple reason they were ahead of their time — the technology needed to make them successful was too immature or simply didn’t exist yet.

Giving cameras the (fast) boot
Fortunately, the various technologies that enable rear-view cameras for cars have reached a sufficient level of maturity, miniaturization, and cost effectiveness. Nonetheless, challenges remain. For example, NHTSA specifies that rear-view cameras meet a number of requirements, including image size, response time, linger time (how long the camera remains activated after shifting from reverse), and durability. Many of these requirements are made to order for a platform like the QNX OS, which combines high reliability with very fast bootup and response times. After all, what’s the use of backup camera if it finishes booting *after* you back out of your driveway?

Domo arigato, for self-driving autos

Lynn Gayowski
When talk moves to autonomous cars, Google's self-driving car is often the first project that springs to mind. However, there are a slew of automakers with autonomous or semi-autonomous vehicles in development — Audi, BMW, General Motors, Mercedes-Benz, and Toyota, to name a few. And did you know that QNX has been involved with autonomous projects since 1997?

Let's begin at the beginning. Obviously the first step is to watch the 1983 Mr. Roboto music video. To quote selectively, "I've come to help you with your problems, so we can be free." As Styx aptly communicated with the help of synthesizers, robots have the potential to improve our lives. Current research predicts autonomous cars will reduce traffic collisions and improve traffic flow, plus drivers will be freed up for other activities.

So let's take a look at how QNX has been participating in the progress to self-driving vehicles.

The microkernel architecture of the QNX operating system provides an exemplary foundation for systems with functional safety requirements, and as you can see from this list, there are projects related to cars, underwater robots, and rescue vehicles.

Take a look at this 1997 video from the California Partners for Advanced Transportation Technology (PATH) and the National Automated Highway System Consortium (NAHSC) showing their automated driving demo — the first project referenced on our timeline. It's interesting that the roadway and driving issues mentioned in this video still hold true 17 years later.

We're estimating that practical use of semi-autonomous cars is still 4 years away and that fully autonomous vehicles won't be available to the general public for about another 10 years after that. So stay tuned to the QNX Auto Blog. I'm already envisioning a 30-year montage of our autonomous projects. With a stirring soundtrack by Styx.

QNX Acoustics for Voice — a new name and a new benchmark in acoustic processing

Tina Jeffrey
Earlier this month, QNX Software Systems officially released QNX Acoustics for Voice 3.0 — the company’s latest generation of acoustic processing software for automotive hands-free voice communications. The solution sets a new benchmark in hands-free quality and supports the rigorous requirements of smartphone connectivity specifications.

Designed as a complete software solution, the product includes both the QNX Acoustics for Voice signal-processing library and the QWALive tool for tuning and configuration.

The signal-processing library manages the flow of audio during a hands-free voice call. It defines two paths: the send path, which handles audio flowing from the microphones to the far end of the call, and the receive path, which handles audio flowing from the far end to the loudspeakers in the car:

QWALive, used throughout development and pre-production phases, gives developers realtime control over all library parameters to accelerate tuning and diagnosis of audio issues:

A look under the hood
QNX Acoustics for Voice 3.0 builds on QNX Software Systems’ best-in-class acoustic echo cancellation and noise reduction algorithms, road-proven in tens of millions of cars, and offers breakthrough advancements over existing solutions.

Let me run through some of the innovative features that are already making waves (sorry, couldn’t resist) among automotive developers.

Perhaps the most significant innovation is our high efficiency technology. Why? Well, simply put, it saves up to 30% both in CPU load and in memory requirements for wideband (16 kHz sample rate for HD Voice) and Wideband Plus (24 kHz sample rate). This translates into the ability to do more processing on existing hardware, and with less memory. For instance, automakers can enable new smartphone connectivity capabilities on current hardware, without compromising performance:

Another feature that premieres with this release is intelligent voice optimization technology, designed to accelerate and increase the robustness of send-path tuning. This technology implements an automated frequency response correction model that dynamically adjusts the frequency response of the send path to compensate for variations in the acoustic path and vehicle cabin conditions.

Dynamic noise shaping, which is exclusive to QNX Acoustics for Voice, also debuts in this release. It enhances speech quality in the send path by reducing broadband noise from fans, defrost vents, and HVAC systems — a welcome feature, as broadband noise can be particularly difficult for hands-free systems to contend with.

Flexibility and portability — check and check
Like its predecessor (QNX Aviage Acoustic Processing 2.0), QNX Acoustics for Voice 3.0 continues to offer maximum flexibility to automakers. The modular software library comes with a comprehensive API, easing integration efforts into infotainment, telematics, and audio amplifier modules. Developers can choose from fixed- and floating-point versions that can be ported to a variety of operating systems and deployed on a wide range of processors or DSPs.

We’re excited about this release as it’s the most sophisticated acoustic voice processing solution available to date, and it allows automakers to build and hone systems for a variety of speech requirements, across all their vehicle platforms.
