Abstract
The present disclosure provides a motor-driven booster type brake system and method thereof. The brake system includes a pedal force sensor for detecting pedal force of a driver applied to a brake pedal, a master cylinder delivering hydraulic pressure to wheel brakes, a booster delivering multiplied force to the master cylinder using a motor, and an ECU controlling the motor based on a detection value of the pedal force. In the brake system, the ECU controls the motor based on hydraulic pressure delivered from the master cylinder to the wheel brakes if an ABS mode is not activated, and controls the motor by maintaining an electric current input to the motor to be within a preset range of electric current if the ABS mode is activated.
