N2 - The PWM solenoid is the critical component of the shift control system. To reduce the electronic flow and power consumption, as well as to offset the influence of the fluctuating voltage and temperature, research on the control characteristic of the PWM solenoid was conducted. After the introduction of the structure and usage of PWM solenoid, the flow equation when it is open and close was established. And through the flow rate balance relationship, the pressure control and amplitude characteristics that can be used in the pilot control and on-off control of hydraulic circuit was obtained. Then based on the differential equation of the control circuit of the PWM solenoid, the precise current control characteristic was obtained to act as the basis for future control. Finally, the testing experiment shows that the calculating pressure and current characteristics conform to the experiment result.
