复杂路况下汽车主动避撞报警技术研究

汽车主动避撞报警技术对提高行车安全有重要意义,但如何减少复杂路况下行车时的误警率是当前需解决的关键问题。通过测量车载信息如汽车转向角度、车速、制动信号、转向灯信号等获知汽车的行驶状态,利用雷达技术感知路况和危险,基于合理的报警算法和控制策略,研制出复杂路况下的汽车主动避撞报警系统。通过实际道路报警试验,结果表明所采取的减少误警率的方法是有效的,所开发的报警系统更趋实用化。

Study on Collision Warning Technology under Complex Road Conditions

Automotive Active Collision Avoidance Warning System,which has been applied,can improve vehicle safety.The key problem,which still remains,is how to decrease the rate of mistake warnings when vehicles are driving under complex road conditions.In this paper,the collision warning system is developed based on logical warning algorithm and reasonable control strategy,which uses the vehicle state information,including steering angle,speed,brake and steering signals,etc.from sensors,and environment information from radar to judge.Some experiments are made on practical road conditions.The results indicate that collision avoidance system which has been described in this paper is effective to decrease mistake warning rate.
