ABSTRACT:
A vehicle braking system can, for example when the performance of a booster has deteriorated, reduce a brake pedal depressing force required to obtain a sufficient braking force and thereby lighten the burden on the driver. A booster and a master cylinder generate a brake fluid pressure in correspondence with an operation of a brake pedal. Wheel cylinders connected to the master cylinder generate wheel braking forces in wheels of the vehicle. It is determined if a vehicle braking state corresponds to a state of operation of the brake pedal, and when it is determined that the vehicle braking state does not correspond to the brake pedal operation brake fluid pressure in the wheel cylinders is increased with a pump. In this way, it is possible to obtain a predetermined braking force corresponding to the brake pedal operation at all times.
