英文摘要：

The electric vehicle power source, switched reluctance motor driving control system were introduced. It prososed design scheme of driving control system by using DSP ＋ CPLD as the primarily controller and detailed analysis of the hardware circuit and software process. The system satisfied the vehicle driving requirement, and it could achieve smooth startup, continuous variable speed,braking,reverse and other functions. The system had a perfomance of rapidity and stability, and the structure of simple and reliable. It was of huge application in electric vehicle.
