Abstract:
1. An assistant starting method of electronic parking brake system for a motor vehicle, characterized in that, the electronic parking brake system receives all sensor signals and detection signals of the motor vehicle, and processes the received signals through a control unit therein, wherein the sensor signals received by the electronic parking brake system from the motor vehicle include an engine rotate speed signal, an effective torque signal output by an engine, a clutch pedal signal, an acceleration pedal signal, an acceleration signal, and a rotate speed or angle of a driving wheel, and wherein a torque Tc transmitted by a clutch is calculated by the control unit based on the engine rotate speed signal and the effective torque signal output by the engine; when any one of the following conditions is satisfied, the brake is released to assist a driver in starting: a first condition where the calculated torque T a second condition where an engine rotate speed is greater than an engine idle speed, and an accelerator pedal and a clutch pedal are depressed simultaneously; a third condition where starting trend of the motor vehicle is detected based on the acceleration signal; a fourth condition where the detected engine rotate speed is lower than a first predetermined threshold value calculated according to a throttle opening data; a fifth condition where a detected rotate speed or angle of the driving wheel is greater than a predetermined threshold value of rotate speed or angle.
