摘　　要：电驱动平地机行驶路况复杂,行驶过程中时常会出现部分电机发生通讯或系统故障,需要在驱动控制过程中采用主动的故障控制机制,以确保车辆安全行驶。当平地机在两侧附着系数相差较大的路面行驶时,易出现单侧驱动轮过度滑转和偏载工况。针对以上问题,基于整车行驶稳定性,对电机故障控制和同步控制策略进行分析,制定了电机故障工况各轮驱动转矩再分配的安全控制解决方案。利用Simulink搭建故障控制器和同步控制器模型,分析故障工况对整车行驶性能的影响。结果表明:故障和同步控制提高了车辆故障行驶的稳定性和通过性。利用设计的故障和同步控制器对车辆在对开路面加速过程的打滑工况进行分析,分析车轮打滑对整车行驶性能的影响,同步控制提高了有效驱动功率,增强了整车通过性和稳定性。Electric drive grader driving road conditions is complex, and there are always some parts of motor communicationor system failure in running, so the active fault control mechanism is need to be used to ensure that the vehicle safedriving. When the grader is running on the road that the friction coefficient of the road is a large difference between the twosides, there is easy to appear unilateral drive wheel over slip and partial load condition. To the above problems, based onthe vehicle handing stability, the motor fault control and synchronous control strategy were analyzed, and the safety controlsolution of the wheel drive torque redistribution in motor fault conditions was established. The model of the fault controllerand the synchronous controller was built based on Simulink, and the influence of the failure mode on the vehicle drivingperformance was analyzed. The results show that the stability and the passing of the vehicle fault are improved by the faultand the synchronous control. The design of the fault and synchronization controller for the vehicle in the process of drivingon the road to speed up the process of the sliding mode, analysis of the impact of wheel slip on the vehicle driving performance,synchronous control to improve the effective driving power, and enhance the vehicle passed and stability.
