带增程器的纯电动汽车整车控制器设计

主要介绍带增程器纯电动整车控制器的设计流程．首先定义整车控制器的功能．通过动力蓄电池荷电状态SOC逻辑门限控制策略，当电池SOC低于门限值后，燃料电池开启，起到增程器的作用．通过仿真软件和数学计算评价整车的经济性和动力性，设定SOC门限值为0．4．使用MPC555芯片作为整车控制器的硬件平台．利用Matlab／Simulink及其子模块Stateflow建立控制模型，通过RTW、TLC等语言编译器生成机器码，使用CANape和MPC555的CAN标定线下载到芯片．最终完成整车调试和标定．

Design of the Vehicle Management System of the Electric Auto with Range - extender

The function of the vehicle management system of the electric auto was defined in this paper. The charging state of battery were used for the control strategy. When the SOC is lower than the threshold, the fuel cell will be started and work as the range - extender. According to the result of the economic and dynamical performance of the vehicle from simulation and calculation, the threshold of SOC was fixed on 0.4. The chip MPC555 was used for the vehicle management system. The model of control strategy is built with Matlab/Simu- link and Stateflow, and then compiled with RTW and TLC into machine language, which is downloaded into chip with CANape and CAN - Bus. Finally the vehicle is tested and demarcated.
