GM Vehicle-to-Vehicle Communication lets cars talk to each other

In the last few months we have heard about several different systems that let cars react to other cars around them when they are on cruise control. GM has taken it one step further with their new system called Vehicle-to-Vehicle Communication, it simply lets cars talk to each other.

By employing a GPS receiver and transponder with special sensors and a special radio frequency to send or receive messages from car to car. Cars will be able to calculate the likelihood of an accident and tell other vehicles that something is imminent unless the vehicles change their course. That could lead to the driver seeing a warning light on their dashboard or even hearing a verbal warning. It is possible that the cars could even take action and hit the brakes if the driver doesn’t respond.

GM believes that their system is superior to the radar-based adaptive cruise control systems used by other makers. Those systems can struggle in heavy fog, rain or snow. The GPS of the V2V system is unaffected by weather.

GM is currently testing the V2V systems in a fleet of Cadillac CTS and DTS sedans.
