Title: VEHICLE BRAKE CONTROL DEVICE
Abstract:
Provided is a vehicle brake control device which is capable of suitably executing brake assistance processing, even if a sensor for detecting the pressure inside a variable-pressure chamber of a vacuum booster is not provided. A brake device 10 is provided with: a vacuum booster 23 for assisting an operation force inputted to a brake pedal 21; a master cylinder 22 which generates MC pressure Pmc corresponding to the assisted operation force; wheel cylinders 11a-11d which are provided to wheels, and in which WC pressure is increased as the MC pressure Pmc is increased; and a brake actuator 30 capable of adjusting the WC pressure. When it is determined that emergency braking is requested, a control device 100 of the brake device 10 sets, as the assistance limit pressure, the MC pressure Pmc at that point in time, and operates the brake actuator 30, to execute brake assistance processing for assisting WC pressure increase.
