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.

The next chapter in car infotainment: seamless mobile integration
Tina Jeffrey |
Allow consumers to bring in content and apps on their mobile devices. We are becoming increasingly attached to our smartphones, and this is driving a trend towards mobile-centric car infotainment. The trend is of particular benefit to buyers of low-end vehicles, in which built-in features such as navigation and speech recognition can be cost prohibitive. A smartphone-driven head unit reduces costs by leveraging the existing connectivity and processing power of the mobile device; it also provides easy access to apps the consumer has already downloaded. In fact, integration between the mobile device and head unit offers numerous benefits: it helps the car keep pace with the consumer-device lifecycle, it endows the car with app store capabilities, and it lets the car connect to the cloud through the mobile device, eliminating the need for a built-in connection.
Using the phone's connectivity and processing power to deliver apps and software updates. |
Leverage and enable the mobile development community to build the apps consumers want. With companies like Apple and Google now in the fray, native brought-in apps will be a certainty, but automakers should continue to embrace HTML5 as an application platform, given its ”write once, run anywhere” mantra. HTML5 remains the most widely used cross-platform application environment and it gives automakers access to the largest pool of developers worldwide. And, as the first W3C vehicle information API specification is ratified, HTML5 application developers will be able to access vehicle information and develop compelling, car-appropriate apps that become an integral part of our daily commute.

12 autonomous car articles worth reading
You know what's fascinating about autonomous cars? Everything. They raise as many questions as they do answers, and many of those questions drive right to the heart of how we see ourselves and the world around us. For instance, will autonomous cars introduce a new era of independence for the elderly? Will they change the very nature of car ownership? Will they reduce traffic fatalities and help make traffic jams a thing of the past?
Technically, legally, economically, and socially, autonomous cars are a game-changer. I like thinking about them, and I like reading what other people think about them. And just what have I been reading? I thought you'd never ask. Here, in no particular order, are 12 articles that have caught my eye in the last month.

And just what have I been reading? I thought you'd never ask. Here, in no particular order, are 12 articles that have caught my eye in the last month.
- Driverless technology and the issue of liability: Who’s responsible? (Inside Counsel) — If autonomous cars are to succeed, law makers must take a balanced approach to liability. Because without it, automakers won’t have the incentive to put autonomous cars on the road and consumers won’t incur the risk of driving them.
- Can We Put a Price on Autonomous Driving? (ECN) — How about a potential financial benefit of $3 trillion per year?
- Big Data Drives The Smart Car (Information Week) — And here you were, thinking the car would drive itself. A look at how “gossiping” cars could make highways both smarter and safer.
- California Regulators Consider “Big Brother” Hazards Of Driverless Cars (MintPress News) — A look at why those gossiping cars need to be careful about what they say and who they say it to.
- Self-driving cars are coming soon and will revolutionize cities and society (GigaOM) — The title sounds over the top, but the article itself provides a nice summary of Brian Ferren’s “five things that autonomous cars need”.
- Can computers drive better than humans? (Fast Company) — Some claim this is pretty easy. But in reality, humans can make highly complex driving decisions almost instantaneously. Will in-car computers be able emulate these decision-making capabilities? If so, how much and how soon?
- What If Your Autonomous Car Keeps Routing You Past Krispy Kreme? (The Atlantic) —And what if it automatically drives you past the home of someone who has a restraining order against you? A look at some of some of the legal potholes that autonomous vehicles will have to negotiate.
- The Problem With Self-Driving Cars: They Don't Cry (Bloomberg Businessweek) — Can self-driving cars make "selfless" decisions that could, for example, put the driver at risk but prevent the car from slamming into a school bus full of kids?
- Government Hitting the Brakes on Driverless Cars (OZY) — To make autonomous cars legal, the rules have to change. Now if we can only figure out who’s in charge of the rules.
- Are magnetic roads the answer to autonomous car accuracy? (Electronic Products) — The idea of using magnets or magnetic strips to guide autonomous is at least 60 years old (see this GM video from 1956). But according to Volvo, magnets embedded into the road can help avoid issues associated with GPS and camera technologies.
- ITU given keys to autonomous car standards process (The Register) — Because I’m a sucker for the Register’s cheeky editorial style.
- Autonomous taxis: Why you may never own a self-driving car (ExtremeTech) — Or why you may end up buying one and renting it out. A look at how autonomous fleets could reduce the number of cars on the road.

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.
