摘　　要：基于模糊函数设计了模糊逻辑控制器,并应用于厦门金龙XMQ6117Y3型客车,通过该控制器产生横摆力矩与主动转向角使客车的横摆角速度与质心侧偏角响应跟踪其期望值。该控制器仿真计算了转向角阶跃输入和正弦输入的客车横摆角与质心侧偏角响应,试验结果表明该控制器能有效改善高质心客车横摆角速度和质心侧偏角响应,使得横摆角速度与质心侧偏角保持在允许范围,从而保证客车行驶的稳定性,减小客车"驶出"或"侧滑"引起"绊倒"侧翻的可能性。Based on the fuzzy function, a fuzzy logic controller is designed,which will be used in Xiamen Golden Dragon XMQ6117Y3. By yaw-moment control and active front steering, it makes yaw rate and vehicle slip angle follow their desired values respectively. In this paper, J-turn and Sine-wave steering simulation is carried out, and the results of yaw rate and vehicle slip angle are received, which show that the fuzzy logic controller is available. It just makes the results follow the desired values well, which has improved the stability of vehicles. Thus it can reduce the possibility of high-centroid vehicle ＂drivingout＂ or ＂slipping＂, which causes ＂trip-rollover＂.
