Abstract:
A parking brake control apparatus (24) stops driving of an electric motor (7A) when a current value of the electric motor (7A) reaches a target current threshold value, when driving the electric motor (7A) to press brake pads (6C) against a disk rotor (4) and hold a braking force. The target current threshold value is a current value for stopping the driving of the electric motor (7A). The parking brake control apparatus (24) changes the target current threshold value according to a rotational acceleration of the electric motor (7A).
