| Abstract: | In the work process of anti-lock braking system(ABS),two three contacts high speed on-off solenoid valve was controlled by the electronic control unit,to realize the brake wheel cylinder pressure turbo-charged,guarantees presses and reduced pressure three kind of conditions controls.In order to enhance the process response speed and control precision,hydraulic ABS which used PWM to control the high speed on-off solenoid valve was researched.The control principle and the operational characteristic of high speed on-off solenoid valve were analyzed.The concrete application of PWM in automobile ABS was illustrated,and the control process of PWM signal was introduced. |
