摘　　要：制动踏板感是驾驶员在制动过程中,踏板力和踏板行程与所期望的车辆减速度匹配程度的主观感受。通过主观评价与客观数据相结合,可以得到理想的客观踏板感目标值,以满足绝大多数驾驶员对踏板感主观要求;制动踏板感是多因素多系统共同影响的结果,为达到较优的踏板感目标值,需要将客观性能指标分解成每个影响因素,量化出每个影响因素的贡献度,才能对其进行有效控制。Brake pedal sense is the subjective feeling of the pedal force and pedal stroke matching with the desired vehicle deceleration speed in the braking process.Through combining subjective and objective data,the ideal target value of objective pedal sense can be obtained to meet the most subjective requirements of the driver s pedal sense.The brake pedal sense is a result of multiple factors and multiple systems.In order to achieve the optimum target value of pedal sense,the objective performance indexes should be decomposed into each influencing factor,and the contribution degree of each influencing factor should be quantified to effectively control it.

关 键 词：制动踏板感 踏板力 踏板行程 贡献度
