BRAKE ASSIST OF ELECTRIC CONTROL STRUCTURE AND METHOD THEREOF

摘要

PURPOSE: An electronic control structure and method for an auxiliary brake is provided to improve fuel efficiency and braking performance by controlling an auxiliary brake using a booster without an electronic control unit and generating hydraulic pressure by moving through a motor. CONSTITUTION: An electronic control structure for an auxiliary brake comprises a brake pedal (100), a motor driven booster (110), a pressure sensor (111), and an electronic control unit (ECU) (112). The brake pedal receives the pedal effort of a driver to deliver to the motor driven booster. The motor driven booster is linked with the brake pedal. The motor driven booster generates hydraulic pressure in a master cylinder through the control of a motor to generate braking power. The pressure sensor is linked with the brake pedal and to the motor driven booster to grasp required for braking pressure and sudden braking situations. The ECU is equipped inside the motor driven booster. The ECU is linked with the pressure sensor to determine the entry and release of an auxiliary brake and control the motor driven booster.
