    • 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.
    • 车辆制动系统可以例如当助力器的性能变差时,减小获得足够的制动力所需的制动踏板下压力,从而减轻驾驶员的负担。 增压器和主缸与制动踏板的操作相对应地产生制动液压。 连接到主缸的轮缸在车辆的车轮中产生车轮制动力。 确定车辆制动状态是否对应于制动踏板的操作状态,并且当确定车辆制动状态不对应于制动踏板操作时,利用泵增加轮缸中的制动液压力。 以这种方式,可以始终获得与制动踏板操作相对应的预定制动力。
