摘　　要：线控转向系统用总线技术取代了方向盘与转向轮之间的传统机械连接,驾驶员无法获得路面信息,需模拟产生路感;通过建立方向盘总成模型,将生物免疫原理与模糊理论应用到路感模拟控制策略中,设计模糊免疫PID控制器用于路感模拟;选取行驶工况为蛇行工况,以20km/h和100km/h作为低速和高速输入进行仿真;结果表明,采用模糊免疫PID控制器控制路感电机模拟产生的路感跟随目标路感力矩的效果更好,适应性更强。For steer--by--wire system , Bus technology instead of the traditional mechanical connection between the steering wheel and the front steering wheel, then the driver can not get the information from road surface, it is necessary to simulate road feel. The model of steering assembly is established, and use the biological immune principles and fuzzy theory for road feeling. A fuzzy immune PID controller is designed so as to control road feel . Selected sinusoidal conditions as driving cycle , the simulation proceed at speed of 20km/h and 100km/h. The results show that the road feeling generated by control the road feeling motor using the fuzzy immune PID controller to sim- ulate which follow the target torque of road feel have better effect and well self--adaptability.
