摘要
通过建立数学模型,以Simulink为平台建立了二轮车辆仿真模型,通过设置不同的滑移率控制策略,让模型在对开路面环境进行仿真试验。通过对比分析不同控制方法下车辆系统左右车轮的各项制动性能参数,表明常规的PID控制下ABS系统的车辆在对开路面制动时左右侧车轮各项性能参数存在较大差异,通过改变期望滑移率参考值之后,制动效果得到明显改善。
A two-wheel vehicle simulation model is established by using Simulink as the platform. By setting different slip rate control strategies, the model is simulated in open road environment. Through comparison and analysis of the various braking performance parameters of the left and right wheels of the vehicle system under different control methods, it shows that there are significant differences in performance parameters of left and right wheels of the vehicles under conventional PID control and ABS brake on open road. After changing the expected slip rate reference value, the braking effect is significantly improved.
