基于直接横摆力矩的电动汽车稳定性控制

摘要

Based on the direct yaw moment control method,this study sets up a 7 Dof vehicle model and an ideal vehicle model,and the stability controller with fuzzy logic control methods is adopted to improve the vehicle yaw stability.The vehicle model is simulated in different conditions,and the results show that the controller is without control of the vehicle and compared,the yaw rate and side slip angle steady-state value set the output is reduced,and improve the stability of the vehicle yaw,through the analysis and testing of this control strategy is effective.%基于直接横摆力矩的控制方法,建立了整车7自由度模型和理想汽车模型,采用了模糊逻辑的控制方法设计了控制器以提高了汽车的横摆稳定性.在不同工况下对汽车进行仿真.结果表明,有控制器和无控制器的汽车相比,汽车的横摆角速度和质心侧偏角的稳态输出值减小,提高了汽车的横摆稳定性,所制定的控制策略是有效的.
