摘　　要：从汽车对转向系统性能要求出发,制定电动助力转向系统的相关控制策略,包括助力控制、回正控制及阻尼控制,并通过相关的软、硬件设计实现该控制策略,可对汽车转向过程的各个环节进行控制 为检验所制定控制策略及所设计控制软件的合理性,进行了电动助力转向系统和进口系统装车对比试验,结果表明,自主研发的电动助力转向系统与进口系统性能接近,不仅转向操纵平顺,而且具有良好的助力特性。A control strategy of the electric power steering(EPS) system, including power assisted control,returnability control and damping control, is proposed according to the requirement of automobile steering system. Corresponding software and hardware are designed for realizing the control strategy. In order to verify the feasibility of the control strategy, comparison experiments are carried out on a vehicle equipped with the developed EPS and the imported EPS, respectively. The results indicate that the developed EPS has similar performance with the imported one. The developed EPS not only works smoothly, but also has proper steering performance, thus can be equipped on passenger cars.
