摘要： An electric parking brake control device has an actuator that drives a motor configured to operate or release an electric parking brake, a control unit that controls the actuator, a storage unit that stores a state of the parking brake, a determining unit that determines the state of the parking brake based on current that flows into the motor, and a detecting unit that detects an ON/OFF state of an ignition switch. When the detecting unit detects that the ignition switch is in the ON state, the actuator sends current in a direction which causes the parking brake to be operated to the motor, and the determining unit determines whether the parking brake is in an operation state or a release state based on the current which flows to the motor.
