Abstract
A target control value of the brake fluid pressure generated in dependence on the braking operation amount is set by using a first coefficient determined in dependence on the vehicle speed in an early phase of a braking operation performed by a vehicle operator and a second coefficient determined in dependence on the braking operation amount and the vehicle speed during a later braking action. The increase in the braking force for the buildup control can be restrained in an early phase of the braking operation so that the onset of deceleration in an early phase of the braking action for the given braking operation can be made gradual in a manner corresponding to the vehicle speed while a favorable buildup control is achieved by increasing the deceleration as the vehicle speed decreases in the course of the braking action.
