The Audi Online traffic light recognition system just might be the next great automotive innovation. It will save you fuel as well as annoyance, by allowing drivers to anticipate changing lights. The system works by reading the automated signals from a city's central traffic computer, and transmitting that information to the driver through the car's Driver Information Display.
At a red light, the system can count down the time remaining until a change to green, as well as prime an engine start-stop system to restart the engine five seconds before that. While on the move, it can also sense whether a car will be able to make it through a green light and--if not--advises the driver to start braking early, preventing abrupt stops.
Audi believes this technology could save significant quantities of fuel in city driving, where the constant start-and-stop nature of traffic can hurt mpg. It could also help smooth the flow of traffic, which would make everyone's morning commute easier.
It's like having a co-pilot tell you how much time you have and how fast you need to go in order to make the next light.
Audi has showcased its production ready online traffic light recognition system at the Consumer Electronics Show this year in an A6 sedan. This system can be integrated with Audi Connect. Audi now says that the system reduces emissions by 15 per cent and can save 900 million litres of fuel if enforced in Germany.
(But they didn't say over what period of time that might happen.)
Audi is currently testing traffic light recognition in Berlin, Las Vegas, and Verona, but says the system is production ready, pending government approval. It said a U.S. launch is the subject of "intense analysis," but did not reveal an on-sale date.
Who wants to give it a test-drive?
