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 is provided with: a vacuum booster for assisting an operation force inputted to a brake pedal; a master cylinder which generates MC pressure Pmc corresponding to the assisted operation force; wheel cylinders which are provided to wheels, and in which WC pressure is increased as the MC pressure Pmc is increased; and a brake actuator capable of adjusting the WC pressure. When it is determined that emergency braking is requested, a control device of the brake device sets, as the assistance limit pressure, the MC pressure Pmc at that point in time, and operates the brake actuator, to execute brake assistance processing for assisting WC pressure increase.

Claim (Index 5):
The vehicle brake control device according to  claim 4 ,\n wherein the vehicle brake control device is configured such that, in a case where pressure obtained by converting the negative pressure in the negative pressure chamber to the hydraulic pressure in the master cylinder is made the negative pressure conversion hydraulic pressure, the negative pressure conversion hydraulic pressure becomes higher as the negative pressure in the negative pressure chamber is higher, the vehicle brake device comprising: an initial gain setting unit which sets a correction initial gain on the basis of the operating speed of the brake operating member at the point in time when it is determined that emergency braking is requested and the negative pressure conversion hydraulic pressure at the same point in time; and a target hydraulic pressure setting unit which calculates a correction gain on the basis of the set correction initial gain, multiplies the correction gain by a difference obtained by subtracting the assistance limit pressure from the hydraulic pressure in the master cylinder, and makes a sum of a product and the assistance limit value a target hydraulic pressure, wherein the initial gain setting unit decreases the correction initial gain as the operating speed of the brake operating member at the point in time when it is determined that the emergency braking is requested is lower and as the negative pressure conversion hydraulic pressure at the same point in time is higher, and the target increase amount setting unit makes a difference obtained by subtracting the hydraulic pressure in the master cylinder from the target hydraulic pressure set by the target increase amount setting unit the target increase amount.
