In recent years, automakers have been testing car-to-car communication technologies in hopes of building a future with vehicles that communicate with one another.

Next year, Federal safety officials plan to test an automotive data exchange whereby vehicles can talk to each other in an effort to warn drivers of possible collisions.

As many as 3,000 cars and light trucks will be fitted with the testing equipment (often referred to as car-to-x technology) in Ann Arbor, Michigan and the results gained from the program are expected to help the National Highway Traffic Safety Administration (NHTSA) decide whether or not to mandate wireless communications in vehicles to help prevent accidents.

The technology works by incorporating GPS systems which allow the individual tracking of various vehicles, along with communal wireless communication that enables the cars to share their location with others and, via onboard computers transmit signals to warn drivers of impending accidents.

Last week, Denso, which hopes to be one of the companies that supplies the technology to automakers, put on a press demonstration in Metro Detroit, showing how, by using the technology, one car was able to send a signal for the driver to brake at an intersection, while another zoomed through, thereby avoiding a collision.

“The technology is here today and it works,” declared Roger Berg, vice president of wireless technology at Denso International America Inc.

A final decision on whether to mandate the technology in new cars and light trucks is expected sometime in 2013.

As part of a national project called SIM-TD, BMW is working on technological advancements to help make driving safer through its next-generation Car-to-X Communication technology. BMW recently conducted several field tests, showing what the technology is capable of, from activating warning lights when a vehicle makes a left turn, to alerting drivers on upcoming traffic lights, to warning them when there are local hazards on the road.

Currently BMW is showing off five of Car-to-X’s features: left-turn assistant, intersection assistant, traffic light assistant, emergency vehicle warning and local hazard warning. The left-turn assistant utilizes vehicle-mounted cameras and GPS to determine when a driver is about to make a left turn. A system of warning lights activate to make sure everything is nice and safe. The intersection assistant is similar, using a system of visual warnings to notify a driver when a vehicle is in an intersection.

The traffic light assistant is pretty clever, working with the traffic infrastructure to inform drivers about upcoming traffic lights and their status. The last two warnings, emergency vehicle and local hazard, are exactly what they sound like, informing drivers ahead of time if an emergency vehicle is approaching or there are any upcoming road hazards.

It will be interesting to see how and if BMW will implement any of these technologies into its future models.
