摘要： A hydraulic brake apparatus for a vehicle includes a supplementary hydraulic pressure source outputting a pressurized output hydraulic pressure and an electronic control apparatus that controls a hydraulic pump in the supplementary hydraulic pressure source. The electronic control apparatus judges whether the hydraulic pump satisfies a predetermined operating condition based on the output hydraulic pressure of the supplementary hydraulic pressure source or not. The electronic control apparatus compares the output hydraulic pressure with a minimum standard hydraulic pressure, detects a drop in the output hydraulic pressure when the output hydraulic pressure is less than a standard hydraulic pressure and determines that the hydraulic pump does not satisfy the predetermined operating condition.

摘要： A hydraulic brake system operates so that under anti-lock control, the braking forces for the rear wheels are enhanced in order to reduce braking loads for the front wheels. Further, upon the occurrence of a malfunction of the anti-locking control, the hydraulic pressure which is supplied to the front and the rear wheels is equalized in order to prevent the rear wheels from locking. In preferred embodiments, a small hydraulic pressure is supplied from a master cylinder to the front wheels while a large pressure is supplied from a brake booster to the rear wheels. Due to the large fluid pressure, the braking forces of the rear wheels are enhanced so that the rear wheels might tend to lock easily. However, anti-lock control can be performed effectively in order to avoid the rear wheels from locking. Upon the malfunction of the anti-lock control, a switching valve is operated so that the brake pressure which is supplied to the front and the rear wheels is equalized. The switching valve operates so that the braking forces of the rear wheels are mutually reduced in comparison to the braking forces of the front wheels. Therefore, it is also possible to prevent the rear wheels from locking if the anti-lock control fails. Thus, the vehicle stability is maintained even if the anti-lock control fails.

摘要： A hydraulic braking system is provided in which the speed of increase of the hydraulic pressure to the wheel cylinders is controlled so that appropriate braking force is ensured while at the same type preventing the road wheels from being positioned in a lock-up condition. In order to provide for such an operation, the locking condition of the road wheels may be detected during braking operation and the anti-lock control system operated so that changeover valves are positioned by a control system so that output pressure of a hydraulic booster is applied to the anti-lock control valves and to the flow control valves so as to appropriately changeover between one of two operating positions in response to the locking condition of the road wheel. In order to provide for such fluid communication of the braking system, a multi-stage orifice arrangement is provided in connection with the anti-lock control valves and the flow control valves.
