ELECTRO-MECHANICAL BRAKE SYSTEM AND CONTROLLING METHOD THEREOF

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.
