摘要： An increase in startup current supplied to a motor is suppressed at an initial stage of starting automatic braking control, while current supply to the motor is performed in a fully energized state after the automatic braking control is started. While output of the motor is increased by controlling the motor in the fully energized state so that a high braking force with high responsiveness is obtained, startup current is prevented from becoming excessive by performing high frequency control only at startup. Thus, decrease in battery voltage is minimized and thus the occurrence of malfunction is minimized in the control systems of various electrical components used in the vehicle.

摘要： The present disclosure relates to a brake control device that supplies hydraulic pressure from a hydraulic pressure supply source to a wheel cylinder through a hydraulic pressure supply passage, and adjusts braking hydraulic pressure, which is the hydraulic pressure in the wheel cylinder by a solenoid valve provided in the hydraulic pressure supply passage, the brake control device including a control unit that, when holding the solenoid valve in an operating state, applies to the solenoid valve a holding current set to greater than or equal to a minimum required current necessary for holding the solenoid valve in the operating state; and a current adjusting unit that adjusts the holding current based on change in braking conditions.
