In particular, the vehicle brake system includes a proportional pressure control valve 80 for generating braking liquid pressure by adjusting the braking energy stored in the auxiliary pressure source 30. Also the vehicle brake system comprises a passage 75 transmitting the liquid pressure generated by a stroke of a brake pedal 1, a switching valve 76 opening the passage in the powered condition and closing the same in the off-powered condition, and an auxiliary control portion 81 activating the proportional pressure control valve 80. Even in the off-powered condition, the high pressure accumulated in the auxiliary pressure source 30 can be used to adjust the required braking liquid pressure at the proportional pressure control valve 80. The switching valve 76 cane be replaces with a relief valve 116 and a return valve 117 for activating the proportional pressure control valve 80 so as to effectively utilize the high pressure of the auxiliary pressure source 30 even in the on-powered condition.

摘要： The antilock brake control apparatus has a locking symptom detector for detecting a wheel locking symptom and a removal of wheel locking symptom. A microcomputer is provided for producing a depressurization signal in response to the detection of the wheel locking symptom until the removal of the wheel locking symptom, and for calculating, after a locking symptom is detected, a pressure difference between the current wheel cylinder pressure and the wheel cylinder pressure when a locking symptom is first detected to obtain a maximum pressure difference at a time when the removal of the wheel locking symptom is detected. The microcomputer further produces a slow pressurization signal in response to the removal of the wheel locking symptom and during an asynchronous state, in which a difference between the wheel speed and the estimated vehicle speed is more than a predetermined range, and a rapid pressurization signal in response to the establishment of the synchronous state, in which the difference is within the predetermined range, and until the wheel cylinder pressure is increased to gain a predetermined percentage of the maximum pressure difference.
