It's no secret that GM has made a commitment to provide the safest vehicles on the road. Now, in expansion of that program, GM is developing a way to keep those who share the road with those cars safe.
GM is developing a driver assistance feature that will be capable of detecting pedestrians and bicyclists on congested streets or in other poor visibility conditions before a driver notices them. This technology relies on WiFi direct, the peer-to-peer wireless standard that allows devices like smartphones to communicate directly with each other rather than through a shared access point like a cell phone tower.
They have also determined that WiFi 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 WiFI.
To tie everything together GM will be developing a free app that smartphone users can download that will alert the vehicles of their presence.
