The invention provides a pilotless automobile braking force response consistency monitoring method and device, and the method comprises the steps: obtaining the braking response characteristics of a service braking system, and calculating the target response time corresponding to each target braking deceleration in real time; the influence of the target braking force at each previous moment on the actual braking force at each subsequent moment is determined through the target response time so as to determine the deviation between the actual theoretical braking force and the actual braking force, and the interference or error influence caused by too large deviation of the single braking force is avoided by obtaining the maximum value and the cumulative average value of the deviation, so that the accuracy of the braking force is improved. The accuracy and the real-time performance of monitoring the response braking force of the service braking system can be greatly improved, and the safety of the vehicle under the unmanned driving working condition is improved.

    本发明提供了一种无人驾驶汽车制动力响应一致性监控方法及装置,通过获取行车制动系统的制动响应特性实时计算各目标制动减速度对应目标响应时间,通过该目标响应时间确定前面各时刻目标制动力对后面各时刻的实际制动力存在的影响,以确定实际理论制动力和实际制动力的偏差,通过获取偏差的最大值以及累计平均值的方式,避免了单次制动力偏差太大干扰或误差影响,可极大提高对行车制动系统响应制动力监控的准确性和实时性,提高了车辆无人驾驶工况下的安全性。
