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 1):
A vehicle brake control device, comprising:\n a vacuum booster which assists operation force inputted to a brake operating member in accordance with differential pressure between a negative pressure chamber and a variable pressure chamber when the brake operating member is operated; a master cylinder in which hydraulic pressure corresponding to the operation force assisted by the vacuum booster is generated; a wheel cylinder provided for a wheel in which inner hydraulic pressure increases as the hydraulic pressure in the master cylinder increases; and a brake adjusting mechanism configured to adjust the hydraulic pressure in the wheel cylinder even when the brake operating member is not operated, wherein the vehicle brake control device is applied to a vehicle in which brake force applied to the vehicle is increased by an increase in hydraulic pressure in the wheel cylinder, the vehicle brake control device further comprising: an assistance control unit which performs brake assistance processing of increasing the hydraulic pressure in the wheel cylinder by a target increase amount based on assistance limit pressure by allowing the brake adjusting mechanism to operate when the vacuum booster reaches assistance limit in a situation in which the brake operating member is operated; and a target increase amount setting unit which, when determining that emergency braking is requested from an operation mode of the brake operating member, makes the hydraulic pressure in the master cylinder at that point in time the assistance limit pressure and sets the target increase amount based on the assistance limit pressure, the assistance control unit performs the brake assistance processing when it is determined that the emergency braking is requested.
