ABSTRACT:
In a vehicle brake apparatus, front-wheel brake power is controlled with fluid pressure brake power (a front-wheel VB fluid pressure part Fvbf+an increase in fluid pressure brake power equivalent to a liner valve pressure difference ΔP1) and regenerative brake power Freg, while rear-wheel brake power is controlled with only fluid pressure brake power (a rear-wheel VB fluid pressure part Fvbr+an increase in fluid pressure brake power equivalent to a liner valve pressure difference ΔP2), so that regenerative and cooperative brake controlling is executed. When a brake pedal is additionally depressed during front/rear brake power proportion controlling, the shortage of the total brake power is compensated by adding additional brake power Fadd, which is the same as rear-wheel brake power shortage ΔFr generated by the additional depression, to the front-wheel brake power.
