摘要： A proportioning valve assembly employs an electromagnetic acuator, such as a proportioning solenoid, associated with a driver circuit. The driver circuit is provided a lead phase circuit for providing a lead phase in supplying a supply current for controlling the valve position of the proportioning valve. Providing appropriate lead time reduces necessity of high gain in attitude change suppression mode operation. Therefore, the response characteristics in pressure adjustment in the shock absorbing mode operation, can be prevented from falling an excessive level.

摘要： A pressure control valve for adjusting a controlled pressure supplied to an actuator includes first and second valves. The first valve serves to modify a pressure level of a working fluid supplied from a fluid pressure source to a preselected level and provides it to the actuator. The second valve is responsive to a control signal commanding elevation or reduction in the controlled pressure from a controller to adjust a supply pressure level from the fluid pressure source to provide a pilot pressure, elevated or reduced to a preselected level, to the first valve for activating same. When elevating or reducing the pilot pressure, the second valve decreases the supply pressure level from the fluid pressure source by a preselected degree, for balancing a flow gain when elevating the pilot pressure with that when reducing the pilot pressure, for providing uniform response for elevation and reduction of the controlled pressure to the actuator.

摘要： A torque is transmitted between a fluid pressure pump driven together with drive of a vehicle, and a fluid pressure motor that rotates together with driven wheels. The fluid pressure motor has two ports, and rotates in accordance with the direction of fluid supply to the ports. Fluid is circulated from one port to the other according to the input of rotation torque from the driven wheels. A high pressure flowpath connected to the pump outlet, and a low pressure flowpath connected to the pump inlet, are connected to these ports, and the connection direction is reversed when the rotation direction of the drive wheels is reversed. The low pressure flowpath is therefore always at low pressure regardless of the rotation direction of the drive wheels, and by controlling the pump supply flowrate so as not to exceed a predetermined value, torque is not transmitted when the vehicle is running at high speed.

摘要： A brake control system for an automotive vehicle has an improved hydraulic circuit network which is capable of performing pressure boosting operation for a pressure supplied from a master cylinder, as well as anti-skid brake control operation and traction control operation. The system includes a valve device for selectively establishing and blocking fluid communication between master cylinder and wheel cylinder. The valve device is generally responsive to the fluid pressure supplied from the master cylinder to enter into pressure boosting mode in response to increase in the fluid pressure from the master cylinder across a predetermined value. An electronically operable boost control device cooperates with the valve device for varying pressure boosting magnitude depending upon vehicle driving condition. An electronically operable traction control device is also provided and cooperates with the boost control device for generating a braking force to decelerate a vehicle wheel irrespectively of manual operation state of brake system when wheel spinning is detected or predicted. The system exhibits high safety level by an enhanced fail-safe function.
