英文摘要：

This paper completes the design of driving current of electronically controlled unit pump solenoid valve.By the module of conversion （A/D） module of microcontroller （MCU）-TC1724,the Peak ＆ Hold driving current of the solenoid valve is sampled,and the high and low switch control signals are outputted by General Purpose Timer Array （GPTA） module of the MCU.Through the analysis of the principle of the driving module and the hardware and software design,the experiment of driving module was finished on electric unit pump.The results show that the driving module satisfies the demand of electric unit pump system.
