Audi traffic light recognition could save 240 million gallons of fuel [UPDATE]

Any hypermiler will tell you that the way you drive your car has a huge impact on how much energy it uses. But these greenfoot drivers haven't had a car that's smart enough to tell them about the inner lives of traffic lights. That's what a prototype system in an Audi A6 Saloon that the German automaker recently tested in Las Vegas can do. Since the car can communicate with local traffic signals and is able to predict when lights will change, the car can help reduce CO2 emissions by up to 15 percent. Further, Audi says that the system could save some 238 million gallons of fuel (900 million liters), if deployed across Germany. We can only imagine what hypermilers could do with this. We got to drive the Audi Online traffic light information system prototype in January, but we focused more on how the system worked rather than the green aspect. Now that Audi has had a bit more time to crunch the numbers, it has released fuel economy information for the connected car. The key points for the eco-side of things are that the driver is told in the dashboard how fast/slow to go to hit the next green light. This can help prevent unnecessary speeding and or encourage drivers to go a bit faster in order to hit the green, thus preventing idling and wasted time. The system is too smart to let you idle for long. Except that Audi Online is too smart to let you idle for long. The Audi connect system can calculate how much longer the light will be red and can access the car's start-stop capabilities and will fire up the engine "five seconds before the green phase." That seems like an awful long time in a world where competitors have figured out ways to restart an engine in 0.35 seconds. We've asked Audi for an explanation on why this buffer is so lengthy, and will let you know what the reasoning is when we hear back. Despite the trials in the A6, Audi says the Audi Online traffic system could be integrated into any Audi model, "subject to the necessary government legislation." Aside from the Sin City tests, Audi is running trials of the connected car in Verona, Italy and Berlin, Germany. If you'd like to test it out yourself some day, take heart from this line in the press release, available below: "A market launch is currently the subject of intense analysis in the United States." *UPDATE: Audi's Mark Dahncke told AutoblogGreen that the five second window is meant, "To alert the driver that the light is about to turn green.

TRANSLOGIC 148: Audi A3 Sportback E-Tron

We get an early drive of Audi's first plug-in vehicle for the U.S. market, the A3 Sportback E-Tron PHEV. Part of Audi's all-new A3 lineup, the Sportback E-Tron boasts an estimated electric driving range of about 30 miles at speeds up to 80 miles per hour. Find out what the future holds for Audi and their E-Tron vehicles.

Are future vehicular hacks inevitable?

Before the hack of the Uconnect system in a Jeep Cherokee resulted in a 1.4-million vehicle recall, the potential software vulnerabilities in vehicles were already a hot topic with Congressional inquiries and even proposed legislation in the US. As cars' interconnected systems gain the ability to go online, they become open to a host of new threats. Automakers are trying to stop this, but it might be too late to put the genie back into the bottle. Throughout 2015, the issue of software security in vehicles has become increasingly vital. For example, the recent Jeep case wasn't even the biggest hack this year. In February, a major flaw was discovered in the BMW Connected Drive service that allowed researchers to remotely lock and unlock the doors and potentially affected 2.2 million cars. The fix was an over-the-air patch for the problem. Automakers are actively working to fix the issues. Mercedes-Benz, BMW, and Audi reportedly are using encrypted connections and firewalls in their vehicles to prevent hacking. "Absolute, 100-percent safety isn't possible," Daimler spokesperson Benjamin Oberkersch said to Automotive News Europe. "But we develop our systems, tested by internal and external experts, so they're up to date." These vulnerabilities seem to be popping up more often. A successful hack took $14 in parts from Radio Shack in one case. There was also a 60 Minutes report earlier in the year about DARPA's ability to hack into OnStar to take control of a Chevrolet Impala. Experts aren't so sure companies can contend with hackers' advancement. "The difficulty for the carmakers at the moment is the question whether they can keep pace with advances in technology, and especially hacking technology," Rainer Scholz, executive director for telematics consultant EY, said to Automotive News Europe. "We seriously doubt they can." At this point, vehicle hacks are coming more from researchers looking for holes than from those with malicious intent. Still, the vulnerabilities are definitely there. It's up to automakers to keep patching the problems before they become dangerous to drivers.
