Vehicle Auxiliary Anti-Collision Warning System Based on Positioning in Electronic Map

After studying the existing methods of collision detection and early warning, a vehicle auxiliary anti-collision warning system based on positioning in electronic map is proposed. In this system, OBD, GPS, vehicle sensor and wireless LAN technologies are used to obtain the driving information of a vehicle itself and other vehicles around, and map positioning technologies to display the positions of vehicles in the map. The collision probability of personalization is used to determine the alarm time. Experiments show that the system can be used in LOS and NLOS scenarios, and can effectively avoid collision among vehicles.
