摘　　要：整车控制技术是电动汽车的核心技术之一,也是我国在新能源汽车领域自主研发能力的体现。基于Freescale公司双核处理器9S12XET256开发了一款通用型纯电动汽车整车控制器。设计时考虑硬件的通用性,使之适用于多种纯电动汽车的整车控制,并以某企业研发的纯电池动力轿车为控制对象,在基于dSPACE的硬件在环仿真系统上进行了一系列仿真试验。试验结果显示:VCU能够准确地控制整车实现多种工作模式下的运行工作状态,初步实现了设计目标。Vehicle Control Technology is one of a core technologies of electric vehicle,it could express self-development capacityof our own country.Based on a dual-core microprocessor 9S12XET256 of Freescale company,this subject developed a universal electrical vehicle controller（Vehicle Control Unit-VCU）.A generality of hardware is considered to make it sure which can be applied to many kinds of Electrical Vehicle（HEV） control.To verify the function of VCU,this article takes a electrical vehicle as the controlled subject and then organizes a series of simulation testing using a hardware in-the-loop simulation system based on dSPACE.The testing indicates that VCU can accurately control the vehicle to achieve working state,verifying the validity of the hardware of VCU.
