Abstract:
A parking brake control device is configured to, when releasing a hold on a braking force, energize an electric motor, and change a drive time of the electric motor based on a current change amount in a predetermined interval after a predetermined time has elapsed since a current value of the electric motor starts to decrease after increasing and a current value at which the current change amount of the electric motor converges to a predetermined value or less.
