Research on multi-point monitoring anti-collision system for vehicle auxiliary driving

Multi-point monitoring anti-collision system for vehicle auxiliary driving is mainly used in advanced vehicle on-board active safety systems, such as forward anti-collision systems, active collision warning systems and adaptive cruise control systems and so on. The system plays an important role in the improvement of vehicle active safety and the reduction of traffic accidents. The stability of vehicle active anti-collision system in dynamic environment is still one of the most difficult problems to break through nowadays. According to driving habit and the existed detecting technique of sensor, combining the infrared laser range and galvanometer scanning technique, design a multi-point monitoring anti-collision system which can be used to assist navigation, obstacle avoidance and the speed control for the vehicle initiative safety. Lots of experiments using the system prototype are made, and main performance of it is under tested. The results of these experiments show that the imaging speed of the system can reach up to 33 frames per second, the detectable distance range 10-200 m. The maximum ranging error is 3.24 m, the minimum ranging error is 0.26 m and the average error is less than 0.46 m.
