摘要： A flow control valve includes a cylinder in which an inflow port, an outflow port and a return port are formed. A spiral choke is formed between the inflow and outflow ports. A working oil introduced from the inflow port into the cylinder flows out from the outflow port through the spiral choke. An actuating valve is arranged in the cylinder so as to open and close the return port in accordance with a difference in pressure between the inflow and outflow port sides of the spiral choke. When the pressure difference exceeds a predetermined value, the actuating valve opens the return port so that a part of the working oil introduced into the cylinder is returned to the inflow side of the flow control valve.

摘要： The characteristic of the suspension is held to be a soft one when the vehicle is running along a flat surface, while it is automatically switched by the switch unit to a hard one when the cycle period T of vertical vibration of the vehicle height becomes near the cycle of the natural vibration of sprung mass of the suspension at the time of running along a road having an irregular surface or jumping a projection, thereby suppressing the resonance of the vehicle body due to external force applied from the road to improve the comfortability.

摘要： A vehicle suspension apparatus including suspension units each provided for each wheel and having an air spring chamber is disclosed. When steering wheel is quickly returned toward the center position at the time of a slalom running, it is detected from the steering angular velocity and vehicle velocity that the vehicle body has begun to be returned to a neutral state, and communication control valves are opened before the reaching of the center position, i.e., before the steering angle reaches an insensitive range. Rolling control thus can be improved without delay in the restoration of the position of the vehicle body even at the time of a high speed slalom running, at which time the steering wheel is repeatedly operated quickly.

摘要： A four-wheel steering system of a vehicle includes a power steering device for steering the front wheels, an oil pressure pump for generating an oil pressure in accordance with a travel speed of the vehicle, and a hydraulic actuator for steering the rear wheels. A first control valve is provided between the pump and the actuator so as to operate upon reception of the oil pressure from the power steering device. This valve introduces the oil pressure from the pump to the actuator in accordance with the oil pressure from the power steering device so that the actuator steers the rear wheels in the same direction as the front wheels. A second control valve is provided between the power steering device and the actuator so as to operate in accordance with the oil pressure from the power steering device. When the oil pressure from the power steering device exceeds a predetermined value, the second control valve operates to introduce the oil pressure from the power steering device to the actuator so that the actuator steers the rear wheels in the opposite direction to the front wheels.

The control unit serves to determine the period or frequency of change or reversal of the direction of the detected transverse acceleration of the vehicle, and control the suspension units so as to stop the roll-suppression control when the frequency of reversal exceeds a prescribed level. The control unit further performs the first roll-suppression control operation and stop subsequent roll-suppression control operations from the instant when the frequency of reversal of the direction of the transverse acceleration exceeds the prescribed level.

摘要： Disclosed is a suspension control apparatus for a vehicle having a plurality of suspension units each disposed between a road wheel and the body of a vehicle for effectively and quickly correcting any deviation of the vehicle height from a normal height level immediately upon finishing of active suspension control operations. Priority is determined for vehicle-height control and various active suspension control operations such as roll control, nose-dive and squat control, and pitching and bouncing control so that normal vehicle-height control is stopped or inhibited during active suspension control operations are being carried out, thereby preventing the traveling attitude of the vehicle from being made unstable. Also, a vehicle-height control determining time interval from the instant when active suspension control operations has been finished until the time when vehicle-height control is restarted is substantially reduced as compared with that required in the case when the vehicle is traveling in a normal attitude without any active suspension control operation, whereby any deviation of the vehicle height from a target height level can be quickly removed to make the actual vehicle height match with a target height level in a very short time immediately after the finishing of the active suspension control operations.
