摘要
介绍了汽车转向系统路感的实现方法和线控转向系统结构,并在对车辆动力学分析的基础上,利用键合图理论对汽车线控转向系统的路感进行了研究。在20-sim键合图仿真软件中给出了线控转向系统键合图模型,利用键合图理论对电机电流和路感进行仿真分析,最后利用执行电机电流反馈方法得到较为理想的路感。
The realization method of steering system＇s road feeling and the structure of SBW were introduced. Based on the analysis of the vehicle dynamics, the SBW＇s road feeling was researched through the theory of Bond Graph. Firstly, in 20-sim Bond Graph Simulation software, the SWB bond graph model was proposed, and by utilizing the bond graph theory, the motor current and road feeling were analyzed and simulated. Finally, an ideally road feeling was obtained through the implementation of the motor current feedback method.
