摘要
为了深入研究驾驶人在应急制动行为下车辆的纵向响应问题,建立了车辆应急制动响应动力学模型;通过驾驶人应急制动行为下车辆纵向应急响应实车试验,完成驾驶人制动操作力度与车辆纵向响应等关键数据的采集,对比分析实车试验数据与响应动力学计算数据;研究结果表明:利用制动踏板位移描述驾驶人的应急操作力度更加准确,并且建立的车辆应急制动响应动力学模型数据误差较小,车辆制动应急响应计算模型70%的数据的相对误差在10%以内,最大相对误差为18.71%。
In order to deeply study vehicle longitudinal response problem under driver＇s emergency breaking operation behavior,vehicle emergency braking system dynamics model is established; and driver emergency brake operating vehicle emergency response to a real vehicle test is designed; driver emergency brake force and vehicle emergency response level data operation were collected,analysis of real vehicle test data and dynamic model calculating values was conduct. The research results show that the brake pedal displacement can better describe the driver the emergency operation the vehicle emergency braking system dynamics model established in this paper,the caloulated data error is small,the vehicle braking emergency response calculation model for the relative error of 70% of the data within 10%,the maximum relative error is 18. 71%.
