GM develops Wifi Direct based Pedestrian and Bicyclist Detector for Cars

General Motors researchers are developing a promising driver assistance feature potentially capable of detecting pedestrians and bicyclists on congested streets or in poor visibility conditions before the driver notices them.

General Motors unveiled today that they work on a new traffic safety feature based on Wi-fi Direct. 

The feature relies on Wi-Fi Direct, the peer-to-peer wireless standard that allows devices like some smartphones to communicate directly with each other rather than through a shared access point like a cell phone tower.

GM researchers have determined Wi-Fi Direct can be integrated with other sensor-based object detection and driver alert systems already available on production vehicles to help detect pedestrians and bicyclists carrying smartphones equipped with Wi-Fi Direct.

The automaker also is looking to develop a complementary app for Wi-Fi Direct-capable smartphones that can be downloaded by frequent road users such as “bike messenger” or construction worker that will help Wi-Fi Direct-equipped vehicles identify them.

Wireless pedestrian detection is part of GM’s ongoing development of vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V) communication systems that could provide advance warning about hazards such as slowed or stalled vehicles, slippery roads or intersections and stop signs.

“This new wireless capability could warn drivers about pedestrians who might be stepping into the roadway from behind a parked vehicle, or bicyclists who are riding in the car’s blind spot,” said Nady Boules, GM Global R&D director of the Electrical and Control Systems Research Lab. “Wi-Fi Direct has the potential to become an integral part of the comprehensive driver assistance systems we offer on many of our Chevrolet, Cadillac, Buick and GMC vehicles.”
