Abstract

The invention discloses a clamping force control system for an electronic mechanical brake of a commercial vehicle and a control method thereof. The control system comprises a signal acquisition module, an upper layer control module, a lower layer control module and an actuator control module; and the control method is that a signal input module is used for transmitting a driver accelerator pedaland a brake pedal operation data signal to the upper layer control module, the upper layer control module judges the driver accelerator pedal operation behavior and control mode and transmits the obtained target clamping force or the linear motion target position signal of a motion conversion device to the lower layer control module, the lower layer control module adjusts the motor target rotationspeed through feedback to adjust the motor current, and finally the execution mechanism is driven to operate and output clamping force through a motor driving unit. According to the clamping force control system and the control method, the accelerator pedal operating behavior of a driver is fully considered, the corresponding control method is set for different control modes, the clamping force control time is shortened, and the braking performance of the vehicle is effectively improved.
