Abstract
A vehicle braking apparatus that can exert high braking performance during vehicle braking is implemented by a control mode that can be realized in a braking apparatus (10) of usual hardware. In controlling the braking apparatus (10) of a vehicle, a climb rate of a wheel cylinder braking oil pressure (Pw) is decreased smaller than a climb rate corresponding to a climb rate of a master cylinder oil pressure (Pm) from a time point at which the wheel cylinder braking oil pressure (Pw) reaches a predetermined threshold value. The time point at which the wheel cylinder braking oil pressure (Pw) reaches the predetermined threshold value (P3) is estimated based on the climb process of the master cylinder oil pressure (Pm) or directly detected.
