Research And Development On The Vehicle's 360° All-round Anti-collision Warning System

In recent years, the safety situation of our state's road traffic is also serious, Collision accidents occur from time to time. If the driver be warned before the accident happened, it will reduce and avoid occurrence of the accidents, and the safety of people and wealth will also be guarded. the Vehicle's 360°All-round anti-collision warning system is the vehicle's equipment which based on improving the active safety of the vehicle and warning the driver before the collisions.Firstly, the outline of the anti-collision warning system is designed, the system include three sub-systems: the main control unit, Speed range of vertical unit, Side-range unit. Based on it, the key technologies involved in the system are determined. Based on analyzing of the vehicle system dynamics, the safety distance model is predigested and improved, some is determined. The software and hardware of the main control unit is designed, And the whole systemis debugged. The system has used the popular vehicle communication manner-CAN Bus, which will improve the reliability and universality of the system.The capability and reliability of the system have been validated by the simulate test. The results of the tests indicate that the system can warnings the driver when the distance between vehicle and barrier is less than the minimum safety distance, and the error and failing warning haven't occurred. It could be used as a vehicle's equipment, and has reached the requirements of designning expectation.
