Patent ID: 8038227

Claim:
A vehicular brake control device for use in a vehicle equipped with a front condition detection sensor for detecting a frontal collision likelihood level indicating a likelihood that a collision with an obstacle in front of the vehicle will occur, a master cylinder pressure detection unit for detecting a brake fluid pressure of a master cylinder and a braking force generating unit, the brake control device performing a manual brake control including a brake assist control and an automatic brake control, wherein: the brake control device, in the automatic brake control, automatically applies braking force to the braking force generating unit entirely independently of an operation of a brake control member that is operated by a driver, the brake control device, in the manual brake control, applies braking force to the braking force generating unit in accordance with the operation of the brake control member by the driver, the brake control device, in the brake assist control, determines a target value of an application pressure and applies the target value to the braking force generating unit, the target value of the application pressure is set based on an assisting application pressure, the brake fluid pressure of the master cylinder detected by the master cylinder pressure detection unit and an upper limit of the target value, the assisting application pressure is set based on the detected frontal collision likelihood level, a provisional value, which is for determining the target value, is calculated by adding the brake fluid pressure of the master cylinder and the assisting application pressure, the upper limit of the target value is set to increase in accordance with an increase of an elapsed time from a start of the brake assist control, and a smaller one of the provisional value and the upper limit is set as the target value.
