| 摘 要： | 以车轮信息为基础，通过对不同路面状况下ABS控制循环过程中车轮速度变化规律的理论分析，总结了车轮速度在不同行驶工况下对参考车速计算的贡献，提出了采用车轮信号以及车辆减速度信号的直线制动车辆车身参考速度的计算算法。编制了Matlab仿真程序并采用道路试验数据进行了仿真分析，仿真与试验结果吻合良好，验证了该算法的有效性。

| Abstract: | Based on wheel speed information, the contribution of wheel speed to the calculation of reference velocity was studied by theoretical analysis on changing rules of the wheel speed signals in an anti-lock brake system (ABS) cycle for various driving conditions. An algorithm was proposed to monitor the reference velocity of a straightly braked vehicle by using wheel speed and vehicle acceleration information. The simulation program was made on Matlab platform with algorithm, and the validity of this algorithm was demonstrated by the perfect coincidence of the simulation and experimental results. |
