An advanced driver assistance system (ADAS) is the premium technology for autonomous driving. It uses data from vision/camera systems, data from in vehicle sensors, and data from vehicle-to-vehicle (V2V) or Vehicle-to-Infrastructure (V2I) communication systems. The next generation systems even autonomous vehicles are expected to use the V2V information to increase the safety for non-line of sight environments. Exchanging some data like vehicle position, speed, status etc., helps to the driver about potential problems, or to avoid collisions. In this paper, a V2V communication system module is designed and tested on the vehicles.
