Abstract:

In general pulse width modulation (PWM) signal driven,the high-speed on-off solenoid valve opening and closing time are longer,slower reaction,which affected the high-speed on-off solenoid valve control performance.In order to improve the control performance of the high-speed valve,on the basis of the analyses in the operating characteristics of high-speed on-off valve,a multi-hybrid driving method was designed to shorten the opening and closing time,reduce the pressure fluctuations in pressure control to improve the control performance of  the valve.In vehicle clutch control,the use of the above method can improve the starting performance,and the engine speed is relatively stable,the driven plate speed increasing trend fluctuation is smaller.
