Brake control apparatus
Abstract:
A brake control apparatus includes a first pressure-applying section connected through a first oil passage to a wheel cylinder; a pump; a communication valve provided on a second oil passage which connects the first oil passage with the pump; a backflow passage connecting a suction side of the pump with a portion between the pump and the communication valve; a pressure-regulating valve provided on the backflow passage; and a control unit. The control unit attains a first state that causes the first pressure-applying section to apply hydraulic pressure to the wheel cylinder, and a second state that causes the pump to apply hydraulic pressure to the wheel cylinder by driving the pump and at least one of the communication valve and the pressure-regulating valve. The control unit actuates the at least one with a delay relative to an actuation of the pump, when switching to the second state.
