多路况下汽车防碰撞及行人保护预警系统设计
Design of Vehicle Anti-collision and Pedestrian Protection Warning System Under Multiple Road Conditions
摘要
Abstract
This study designs a comprehensive warning system of vehicle anti-collision and pedestrian protection. This warning system combines millimeter wave radar anti-collision system with ultrasonic radar side blind pedestrian protection system, which realizes the combination of vehicle longitudinal and lateral automatic protection. Besides, through the introduction of adhesion coefficient parameter, the calculation model of vehicle safety distance under multiple road conditions is established. What’s more, by using multi-sensor technology, it realizes the real-time monitoring of the driver state;consequently, the system false alarm rate can be reduced. This comprehensive warning system designs a kind of control panel which assembles display, sound, light alarm and mode selection. The test results show that according to multiple road conditions this system can establish vehicle safety distance model and make identification and immediate response to the vehicle and pedestrian that are at different speed from sides; in addition, alarm display control panel has simple operation and friendly interface. And the relative error between the results of safety distance model and the results of MATLAB simulation is within 7%. This system owns higher environmental adaptability, which greatly improves the automatic safety of vehicle driving.关键词
