Abstract
Disclosed is an electronic parking brake system including an electronic parking brake provided to provide a clamping force necessary for parking a vehicle by a motor, a warning unit provided to warn a failure of the electronic parking brake, a current sensor provided to detect a current of the motor, and a controller electrically connected to the current sensor, wherein the controller determines whether a clamping force is generated depending on the motor current in a parking operation, counts a clamping force non-generation time when the clamping force is not generated, and warns a suspected failure of the electronic parking brake through the warning unit when the clamping force non-generation time elapses a preliminary failure detection time set shorter than a failure detection time of the electronic parking brake.
