摘　　要：在电动汽车整车控制器(VCU)开发过程中,经过实车测试,发现初始设计的VCU的电磁兼容性能较差,AD值采集易受干扰,同时功能不够完善。采用隔离方案对控制器硬件进行了改进设计,应用MBD方式进行了控制策略的完善和实现。试验结果表明,改进后的整车控制器AD值采集受干扰问题得到明显改善,控制器正确地实现了驾驶员意图和故障处理功能。In the development of Vehicle Control Unit （VCU） for electric vehicle, it is found that VCU EMC performance is poor in the initial development process by analyzing the real electric vehicle test data, AD value acquisition is easy to be interference, at the same time the function is not perfect. The hardware design of VCU was improved by isolation method, perfecting and realizing the control strategies using MBD. Experimental results show that the AD value acquisition is significantly improved; the driver＇s intention and fault diagnosis treatment are correctly implemented.
