The function improvement method for the millimeter wave radar of the cooperative adaptive cruise control system provided by the invention comprises the following steps: judging signal states of all targets currently detected by the millimeter wave radar of the cooperative adaptive cruise control system by using anomaly detection based on data association; the signal state comprises three conditions of target loss, false target and target normal, and defining the target loss and the false target as signal abnormity; if it is judged that the current signal state is a target loss or false target, it is indicated that the millimeter wave radar is insufficient in function or misused in function, and a risk reduction method is started to reduce the risk of the millimeter wave radar of the cooperative adaptive cruise control system; the risk reduction method comprises the following steps: firstly, starting a signal correction scheme, and then deciding to take one or more measures of abnormal alarm, request takeover and degradation processing. The method disclosed by the invention can ensure safe and stable operation of the queue.

    本公开提供的协同自适应巡航控制系统毫米波雷达的功能改进方法,包括:使用基于数据关联的异常检测,对面向协同自适应巡航控制系统的毫米波雷达当前检测到的所有目标的信号状态进行判定,信号状态包括目标丢失、虚假目标和目标正常三种情况,将目标丢失和虚假目标定义为信号异常;若判定当前信号状态为目标丢失或虚假目标,则说明毫米波雷达存在功能不足或功能误用,启动风险降低方法以降低协同自适应巡航控制系统毫米波雷达的风险;所述风险降低方法,首先启动信号修正方案,然后决定采取异常警报、请求接管和降级处理中的一种或多种措施。本公开方法可保证队列安全稳定地运行。
