摘　　要：为了提高车辆在复杂工况下的稳定性能,设计了基于分层控制的电子稳定控制系统(ESC)。系统的上层控制器以横摆角速度和质心侧偏角为控制变量,采用模糊PID算法计算出车辆维持稳定所需的横摆力矩;下层控制器根据上层输出的所需横摆力矩计算得出被控车轮的滑移率变化量,然后采用变参数PID算法对车轮进行滑移率控制,从而实现车辆所需的横摆力矩。最后,应用Matlab/Simulink验证了该控制算法的有效性,并将该算法移植到单片机做冬季实车场地试验,单移线和双移线工况试验结果表明了该算法的工程实用性。In order to improve the vehicle stability under complex working condition, an electronic Stability control system based on hierarchical strategy is proposed. The up layer of the controller is a fuzzy Proportional-integral-derivative （PID） controller, and the controlling variables are the yaw rate and the side-slip angle. The desired yaw moment is calculated by the upper layer. The target slip rate is calculated based on the relationship between the yaw moment and the slip rate. Then, the lower layer is applied to control the slip rate. Finally, the ESC algorithm is verified by Matlab/Simulink. The winter road test shows that the proposed control strategy can improve vehicle stability performance.
