摘  要:为提高车辆的横向稳定性,获得良好的操纵性能,利用ADAMS/car和MATLAB/simulink建立了以横摆角速度和质心侧偏角为控制变量的多级PID仿真模型,分别采用了单个车轮制动和单侧车轮制动产生附加横摆力矩的方式。通过蛇形试验验证了ESP控制器的有效性和对比了2种制动方式的控制效果。仿真试验表明:采用该ESP控制器可以很好地保持车辆的稳定性,采用单侧车轮制动产生附加横摆力矩的方式具有更快的控制速度和更好的控制效果。In order to enhance the vehicle's lateral stability and obtain good maneuvering performance, based on ADAMS/car and MATLAB/simulink a multi-class PID simulation model with the control variable of yaw rate and sideslip angle is established. Single wheel brake and side wheels brake is used to generate additional yaw moment. The snake-like experiment tested the effectiveness of the ESP controller and the control effects by adopting this two different braking ways is compared. The simulation results showed the ESP controller which adopts the yaw rate and sideslip angle variables can maintain the vehicle stability well and it would get faster control speed and better control effect when adopting the way of side wheel brake generating additional yaw moment.
