摘要
针对目前主动横摆力矩控制算法存在的问题,提出了基于门限自调整的PD控制算法,即利用逻辑门限值方法产生并调整PID控制器参数,并由PD算法产生车轮制动力矩实现车辆稳定控制。利用MATLAB/Simulink软件建立了该控制算法的仿真模型,分别在高附着路面和低附着路面进行了仿真分析。结果表明,该算法在各种工况下均能很好保持汽车稳定性。
To solve the problem existing in the current active yaw-moment control algorithm,a PD control algorithm based on threshold self-correcting is presented,e.g.use logic door limit method to generate and correct PID controller parameters,and achieve vehicle stability control with the wheel braking moment generated with PD algorithm.A simulation model of this control algorithm is established with software MATLAB/Simulink,which is simulated and analyzed in high adhesion road surface and low adhesion road surface.The results indicate that this algorithm can keep vehicle in good stability under different operating conditions.
