Abstract
A braking force increasing device composed of a pump and a control valve continuously increases brake-fluid pressure of wheel cylinders when a brake pedal is operated by a driver and a variation of driver's operation of the brake pedal is within a predetermined range. As a result, even when the driver keeps the brake pedal depression at a certain stroke substantially, braking force can be gradually increased. Therefore, it is not necessary for the driver to depress down the brake pedal more strongly to cause braking force to be applied to the vehicle.
