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： In a hydraulic brake system for a vehicle, the brake fluid in a first wheel brake and the brake fluid in a second wheel brake which are hydraulically connected to a pressure generating chamber of a master cylinder are individually caused to flow into a low back pressure reservoir with the aid of an electromagnetic change-over valve and first and second electromagnetic cut-off valves; and with a pump driven by an electric motor, the brake fluid flowing in the low back pressure reservoir in the above-described manner is caused to flow through a first check valve and a first orifice to the first wheel brake, and through a second check valve and a second orifice to the second wheel brake. With the pump operated, the first and second electromagnetic cut-off valves are individually operated, so that the first and second wheel brakes are individually decreased or reincreased in hydraulic pressure. For traction control, electromagnetic change-over valves provided in bypass passages are operated. Thus, with the system, anti-lock control and traction control can be achieved, and, even when the valves added for traction control become out of order, brake fluid can be supplied to or drawn from the wheel brakes as required.

The system includes an auxiliary pressure source which has an inlet for introducing the brake fluid and an outlet connected to the pressure circuit for discharging thereinto the pressurized brake fluid. A circulation passage is disposed between the outlet and the inlet for communicating with each other. An auxiliary valve is disposed in the circulation passage so as to open or close the passage. An auxiliary reservoir is connected to the circulation passage between the valve and the inlet of the source. The auxiliary reservoir has a capacity for storing a predetermined amount of brake fluid. And, a controller is provided for driving the source and actuating the valve so as to open or close the circulation passage. Accordingly, the brake fluid discharged from the pressure source is fed into the pressure circuit when the valve closes the passage, while the brake fluid discharged from the pressure source is circulated in the circulation passage via the valve when the valve opens the passage.

摘要： A brake hydraulic pressure generator is proposed which is simple in structure and can suppress fluctuations in the brake pedal operating amount due to fluctuations in the amount of brake fluid consumed in the brake circuit. The brake hydraulic pressure generator includes an input shaft operated by a brake pedal, a stroke simulator for imparting a stroke and a reaction force corresponding to the brake pedal operating amount to the input shaft, a master cylinder for generating brake hydraulic pressure, and a pressure detector member for applying a reaction force corresponding to the hydraulic pressure in the master cylinder to a valve member of the control valve. The reaction force is transmitted through the pressure detector member to the control member. The input to the brake pedal is transmitted to the control valve through the stroke simulator so as to oppose the reaction force. The control valve operates to balance the reaction force and the input.
