混合动力汽车整车控制器开发与试验

基于飞思卡尔公司的双核微控制器9S12XDT512开发了一款通用的混合动力汽车（HEV）整车控制器（VehicleControl Unit-VCU）,设计时考虑硬件的通用性,使之能够适用于多种混合动力汽车的整车控制。为验证VCU功能,本文以某款并联混合动力公交车为控制对象,在基于dSPACE的硬件在环仿真系统上进行了一系列仿真试验。试验结果表明：VCU能够准确地控制整车实现混合动力工作状态,进而验证了VCU硬件的有效性。

Development and Testing of Vehicle Control Unit for Hybrid Electrical Vehicle

A general-purpose Vehicle Control Unit （VCU）was developed using a Freescale＇s mierocontroller （9S12XDT512）with dual cores. In the development of VCU, generality of hardware was considered to make sure it could be applied to many kinds of Hybrid Electrical Vehicle （HEV）control. To verify the function of VCU, this article took a hybrid elec.trical bus as the controlled subject and then organized a series of simulation testing using a hardware in-the- loop simulation system based on dSPACE. The testing indicated that VCU could accurately control the vehicle to achieve hybrid working state, verifying the validity of the hardware of VCU.
