Abstract: The present disclosure relates to a zero-drag control device of an EMB system and a zero-drag control method using the same, which effectively control a drag phenomenon. By adjusting a gap between a disk and a pad in consideration of not only a braking intention through a brake pedal but also an accelerating intention through an accelerator pedal, the drag phenomenon can be effectively controlled and the braking response can be improved.

Abstract: The present disclosure relates to a brake system which controls a piston through force control and position control of an electronic actuator to press a disk and provide braking force and is installed in a vehicle to determine whether a failure has occurred and output a safety mode through an indicator when a failure occurs. The brake system comprises a control unit that controls a position of the electronic actuator to provide braking force and compensates the braking force based on a deceleration of the vehicle when the safety mode is output through the indicator.

Abstract: Disclosed herein are an electro-mechanical brake system and a controlling method thereof. The electro-mechanical brake system according to the present embodiment includes a driving part including a motor configured to generate a driving force and a brake pad configured to brake a vehicle or release braking by moving forward and backward with respect to a disc by the motor, a sensor part including a first sensor configured to output a signal corresponding to a stroke of the motor, a second sensor configured to output a signal corresponding to a force applied from the disc to the brake pad, and a third sensor configured to output a signal corresponding to an active brake condition of the vehicle, a controller configured to estimate and update a contact point between the disc and the brake pad, whenever a braking input of the brake pad or release thereof occurs.
