摘　　要：在电动汽车整车控制器(VCU)开发过程中,发现在零部件发生故障时,电动车会有异常表现,必须加入必要的故障诊断与处理策略来实现部件保护和行车安全的功能。应用基于MBD方式的模块化设计方法,根据整车动力系统方案,设计并完善了整车控制策略。试验结果表明,整车控制策略能正确解析驾驶员驱动意图,能在制动过程中回收能量,能及时诊断故障并做出相应的处理,实现预定的功能。In the development of Vehicle Control Unit （VCU） for electric vehicle, it is found that unexpected appearance occurred when parts error happened, so additional failure diagnosis ＆ safety management strategy is needed to protect important parts and ensure driving safety. Vehicle control strategy is designed and improved according to power-train framework using modular design method based on MBD. Experimental results show that the control strategy can correctly implement the driver＇s intention, recover energy during brake, it can diagnose the failure and make the relative actions, realizing the predetermined function.
