摘　　要：跑偏是汽车使用过程中的常见故障之一,严重时可导致安全事故。提出一种基于电动助力转向系统(EPS)的汽车跑偏补偿方法,该方法通过对行驶工况的辨识,由助力电机提供纠正跑偏的补偿力矩。建立了基于Car Sim与Matlab/Simulink的EPS汽车联合仿真平台,并对该方法的有效性进行了仿真验证。仿真结果表明:基于EPS的跑偏补偿可以防止汽车跑偏,减少驾驶员驾驶疲劳,保证驾驶安全。Driving wandering is a typical failure on vehicle driving, which may lead to safety misadventure. This paper introduces a compensation method for vehicle driving wandering based on automotive electric power steering（EPS）. While the tendency of the vehicle to pull to one side is detected, a compensation torque of EPS will be applied to help the vehicle travel straight. In order to validate this method, Co-simulation platform based on Car Sim and Matlab/Simulink is established.The simulation shows that torque compensation of EPS can pull vehicle to travel straight, reduce the driving fatigue and ensure the driving safety.
