Bad idea, good idea

Why equip cars with external-sounding speakers? I thought you'd never ask. As it turns out, it can be a really bad idea. Or a really good one.

Here, for example, is a case where bad arguably prevails:

No doubt, the person who devised this system in 1931 thought it a brilliant, or at least entertaining, idea. Fortunately, common sense prevailed and the era of the "auto speaker," with its potential to scare the living daylights out of pedestrians, never came to pass.

But here's the thing: equipping cars with external-sounding speakers can be a great idea, when done for the right reasons. For example, some hybrid and electric vehicles are dangerously quiet for bicyclists and visually impaired pedestrians. Adding speakers to emit audible alerts or to project synthesized engine sounds can be just what the doctor ordered. Or rather, what the parliament ordered: earlier this month, members of the European Parliament stated that they want automakers to install acoustic alerting systems in hybrid vehicles by July 2019.

Mind you, safety isn't the only reason to project synthesized engine sounds. For example, fuel-saving techniques can make even powerful engines sound wimpy — a problem when high performance is a key ingredient of a car's branding. In that case, the automaker may wish to project synthesized engine sounds over both external and internal speakers. The speakers can help preserve the car's wow factor (provided they're not too loud) and the internal speakers, in particular, can make it easier for car owners who drive manual to shift gears by ear. The QNX concept car for acoustics offers a good example of this technology in action.

All of which to say, engine sound enhancement, also known as ESE, is here to stay. And it's not a bad time to be in the automotive-speaker business, either.

QNX helps drive new autonomous vehicle project

Have I ever mentioned the QNX-in-Education program? Over the decades, it has supported an array of university research projects, in fields ranging from humanoid robotics to autonomous aircraft. Harvard University, for example, has been a program member for more than 20 years, using QNX technology to measure and analyze ozone depletion in the stratosphere.

So, on the one hand, QNX Software Systems supports scientific and engineering research. On the other hand, it's a leader in automotive software. You know what that means: it was only a matter of time before those two passions came together. And in fact, QNX has just announced its role in DEEVA, a new autonomous car project from the Artificial Vision and Intelligent Systems Laboratory (VisLab) of the University of Parma.

The folks at VisLab already have several autonomous projects under the belts. Last year, for example, they launched a self-driving car that can negotiate downtown rush-hour traffic and complex situations like traffic circles, traffic lights, and pedestrian crossings. DEEVA incorporates the team's latest insights into autonomous drive and features a rich set of sensors that deliver a complete 3D view of the circumference of the vehicle.

With its 30-year history in safety-critical systems, QNX OS technology offers a natural choice for a project like DEEVA. According to Professor Alberto Broggi, president and CEO of VisLab, "in the design of our vehicle, we selected building blocks offering high reliability with proven safety records; the operating system powering the vital elements of the vehicle is one of those and is why we chose the QNX OS.”

The QNX OS controls several systems in DEEVA, including path and trajectory planning, realtime fusion of laser data and visual data, and the user interface.
