Electric parking brake control device
Abstract:
An EPB-ECU is an electric parking brake control device which generates a braking force by driving an electric motor to press pads and to a disc rotor. The EPB-ECU includes a current supply unit for supplying a motor current to the electric motor and stopping the supply of the motor current when the motor current reaches a predetermined target current value, a supply time measurement unit for measuring a supply time of the motor current, a waiting time setting unit for setting a waiting time from when the supply of the motor current is stopped to when the supply of the motor current is restarted next time on the basis of the measured motor current supply time, and a control unit for instructing the current supply unit to supply the motor current according to the set waiting time.
