Abstract:
1. A brake control device for a vehicle comprising: a hydraulic brake device including: a differential pressure control unit which operates the pump and which transmits a differential pressure instructing output to the differential pressure control valve to perform a differential pressure control such that a differential pressure corresponding to the differential pressure instructing output is generated; wherein the differential pressure control unit is configured to: calculate, when the differential pressure generated by the differential pressure control valve is to be increased during operation of the brake operating member by the driver, an amount, which corresponds to an amount by which the fluid pressure of the wheel cylinder is to be increased by the differential pressure control unit, by which the fluid pressure of the master cylinder will decrease relative to the fluid pressure of the master cylinder when the fluid pressure of the wheel cylinder is not increased by the differential pressure control unit; correct the differential pressure instructing output by the calculated amount by which the fluid pressure of the master cylinder will decrease; and transmit, to the differential pressure control valve, the differential pressure instructing output which has been corrected by the calculated amount by which the fluid pressure of the master cylinder will decrease.
