摘要
文章通过汽车理论和制动性性能的分析,建立包含汽车运动、车轮运动和车轮纵向摩擦力的汽车动力学模型。利用Matlab/Simulink仿真软件,建立汽车模型、制动器模型、轮胎模型和PID控制系统仿真分析模型,进行控制系统的仿真分析。并利用PID控制器以滑移率为控制目标,制动距离和制动时间为主要输出量,仿真研究汽车在不同的路面条件下的控制效果。仿真结果表明PID控制,在不同的路面条件下均可实现对车辆性能的有效控制。研究结果为提高汽车的制动安全性,提供了有益的参考。
Based on automobile theory and braking performance analysis, automobile dynamics model,wheel motion and wheel longitudinal friction model is established. Simulation model of automobile dynamics,braking system,wheel and PID controller is established for analysis automobile braking performance by using Matlab /Simulink software. Slip rate is used as PID controller target,barking distance and braking time is the main output parameter. The control effect of automobile driving on different road conditions is simulated by using Simulink. The simulation results show that PID controller can achieve control effectively in different road conditions. The research results can provide a useful reference for improving braking safety of automobiles.
