摘　　要：针对新能源汽车防抱死问题,采用PID控制算法和模糊控制对以滑移率为基础的防抱死制动控制器设计方案进行构建,通过所构建的路面识别系统,实现了行驶于不同路面上的汽车对最佳滑移率的自动选择过程。通过Matlab仿真实验,能够证明模糊PID控制算法的响应速度和控制精度,稳定性及安全性均得以有效提升。Aiming at the anti-lock braking problem of new energy vehicles, this paper uses PID control algorithm and fuzzy control to construct an anti-lock brake controller design scheme based on slip rate, and realizes driving through the constructed road recognition system. The automatic selection process of the best slip rate can be selected when the car drives on different roads. Through Matlab simulation experiments, it can be proved that the response speed, control accuracy, stability and safety of the fuzzy PID control algorithm can be effectively improved.
