The invention discloses a system and a method for objectifying subjective evaluation of brake pedal feeling. The system comprises a vehicle satellite receiver, and a satellite antenna, a pedal force acquisition device, a pedal travel acquisition device, a brake deceleration acquisition device and a pedal limiting device which are in signal connection with the vehicle satellite receiver. Pedal strokes s of different sizes are set by adjusting a pedal limiting device, a vehicle pedal is quickly stepped to the set pedal stroke from the initial state, the set pedal stroke is kept till the vehicle speed is lower than 5 km/h, a time-varying curve of the deceleration a in the process is recorded, an unstable part is removed, and the average value of the vehicle deceleration a after middle stabilization is recorded. According to the system, the pedal limiting device is arranged, pedal strokes of different sizes are set, unstable data at the head and the tail are removed, the average value of the stabilized deceleration is taken as the deceleration of the corresponding pedal stroke, multiple sets of data are measured to form a matrix, and the tested data are more accurate.
本发明公开了一种将制动踏板感主观评价客观化的系统及其方法,该系统包括车辆卫星接收器、以及与车辆卫星接收器信号连接的卫星天线、踏板力采集装置、踏板行程采集装置、制动减速度采集装置和踏板限位装置。通过调节踏板限位装置来设定不同大小的踏板行程s,将车辆踏板快速从初始状态踩至设定的踏板行程,保持设定的踏板行程直至车辆车速低于5km/h,记录过程中减速度a随时间变化曲线,去掉不稳定部分,记录中间稳定后的车辆减速度a的平均值。本发明的系统通过设置踏板限位装置,采用设定不同大小的踏板行程,并去掉首尾不稳定的数据,取稳定后减速度的平均值为对应踏板行程的减速度,测量多组数据形成矩阵,使得测试的数据更加准确。
