摘要： A wheel brake pressure controlling system includes a brake pressure operating circuit for selectively supplying to a wheel brake a primary pressure generated by a vacuum booster in response to the depression of a brake pedal and a secondary pressure generated by a hydraulic pressure pump which is driven by an electric motor, a microcomputer for estimating a turning of vehicle, determining if a turning of the vehicle is in a over- or under-steer region, and for determining a wheel brake, the pressure of which is to be intensified if the turning of the vehicle lies in the over- or under-steer region, and an output controller for supplying the secondary pressure to the wheel brake which has been thus determined, through the brake pressure operating circuit. The microcomputer determines if the turning of a vehicle occurs in a reference region located outside the over- or under-steer region, and whenever the turning of the vehicle occurs in the reference region, drives the second source of pressure for generating the secondary pressure, determines a wheel brake which is to be intensified, and automatically intensifies the wheel brake.

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.

摘要： An electromagnetic valve device includes a valve body having a first fluid chamber, and inlet and outlet passages fluidly communicating with the first fluid chamber. In a first fluid chamber, a first movable member is slidably received within a stationary sleeve to define a second fluid chamber within the sleeve. The second fluid chamber is in continuous fluid communication with the first fluid chamber and is in fluid communication with the inlet passage. The first member has a first valve for selectively interrupting fluid communication between the inlet passage and the first fluid chamber, and is urged by a return spring into a first position to effect fluid communication between the first fluid chamber and the inlet passage. A second movable member operatively connected to an electromagnet has a second valve for selectively interrupting the fluid communication between the inlet passage and the second fluid chamber. The second member is urged by a return spring into a non-energized position in which fluid communication between the second fluid chamber and the inlet fluid passage is interrupted when the first member is positioned in the first position. When the electromagnet is energized, the second member moves to an energized position and the first member is moved by the second member into a second position to interrupt fluid communication between the inlet passage and the first fluid chamber. A pressure differential between the inlet and outlet passages greater than a predetermined pressure differential holds the first member in the second position so that restricted fluid communication occurs between the inlet and outlet passages when the electromagnet is de-energized.
