摘　　要：为解决四轮驱动汽车转向轻便性和路感之间的矛盾,提出了一种基于模糊PID控制的电动助力转向控制策略。首先,建立电动助力转向系统动力学模型。然后,设计基于模糊PID控制方法的电动助力转向控制策略,最后,借助Matlab/Simulink进行离线仿真,验证所提控制策略的有效性。结果表明,所提控制策略能够较好地实现四轮驱动汽车的电动助力转向系统功能。In order to resolve the contradiction between steering portability and road feel of four-wheel drive vehicle,anelectric power steering control strategy based on Fuzzy PID control was proposed.Above all,a dynamic model of electricpower steering system was established.Then an electric power steering control strategy was designed on the basis of thefuzzy PID control method.Finally,the effectiveness of the proposed control strategy was verified by means of Matlab/Simulink.The results show that the function of electric power steering system can be realized by the control strategy.
