中文摘要：

在汽车驾驶模拟器的研发中。对于转向盘回正系统的模拟，可以增强驾驶员操作时的触感，使交通安全实验数据更加可靠。从转向盘回正力矩数学模型研究出发，采用直流力矩电机作为模拟系统中回正力矩的生成部件，设计了整个转向盘回正‘模拟系统的组成，提出了相应的控制策略。

英文摘要：

In the study of the vehicle driving simulator,the imitation of the steering wheel return system can increase the tactility of.driver＇s action and be more reliable of the traffic safety experimental date.This paper researches mathematical model of the steering wheel aligning torque and regards the direct current moment motor as an unit of steering wheel aligning torque And then this paper discusses the composition of the steering wheel aligning torque simulation system and analyses the control strategy.
