摘要： An actively controlled suspension system has two hydraulic systems for generating damping force against the vibration to be transmitted between a vehicle body and a suspension member. One of the hydraulic systems is designed for absorbing relatively high frequency vibration generally input from the suspension member for preventing vibration from the suspension member from being transmitted to the vehicle body. The other hydraulic system is active on relatively low frequency of vibration generally input from the vehicle body upon change of attitude of the vehicle body. The other hydraulic system generates a fluid pressure suppressing the attitude change. A pressure control valve and a fluid pressure source may be incorporated in the second hydraulic system so that they may not be active when aforementioned one of the hydraulic system is active.

摘要： An actively controlled suspension system introduces two-way mode operation in controlling suspension. A suspension control system operates in a normal mode for controlling fluid pressure in a hydraulic cylinder disposed between a vehicle body and a suspension member is adjusted depending upon the vehicle driving conditions in order to suppress vehicular attitude change, and a power OFF transition mode for controlling the fluid pressure toward a preset neutral pressure. The hydraulic circuit is constructed to maintain the pressure in the working chamber of the hydraulic cylinder at the neutral pressure while power is not supplied to control system.

摘要： A suspension control system for an automotive vehicle is designed for effectively suppressing pitching motion and whereby regulating vehicular attitude. The suspension control system monitors pitching moment to be exerted on the vehicle for adjusting response characteristics in pitching-suppressive control depending upon the magnitude of the pitching moment to be exerted. The suspension control system adjusts the response characteristics of the front and rear suspensions independently of each other according to preset pitching-suppressive control coefficients respectively for the front and rear suspensions, which are set depending upon the suspension characteristics and/or suspension geometory of the vehicle, to which the suspension control system is to be applied.

摘要： An actively controlled suspension system employs a shut-off valve which is responsive to a source pressure dropping below a predetermined level to shut-off communication between a pressure return line for returning the fluid pressure to the pressure source from a hydraulic cylinder. The shut-off valve is disposed in a drain line connecting a drain port of a spool valve assembly and the pressure source. By the presence of the shut-off valve, substantial pressure difference between the hydraulic cylinder side and pressure source side of the spool valve is not created. Therefore, no leakage through the spool valve occurs and whereby the pressure in the hydraulic cylinder can be maintained even when the source pressure becomes substantially low or zero.

摘要： A vehicle turning behavior control apparatus for use with a multi-wheel automatic vehicle. The apparatus provides a difference between the braking forces applied to the nearside and offside wheels of the vehicle to produce a yaw moment in a direction to which the vehicle turns. The difference is determined based upon the vehicle steering angle and is modified based upon the vehicle lateral slip angle.

摘要： In order to improve the cornering of a vehicle under braking, control is based on the single angle and the rate at which the steering angle is changing. When the rate at which the steering angle is changing is high the braking force on the outboard side of the vehicle with respect to the direction in which it is turning, is reduced with respect to that on the inboard side while in the case that the steering angle is relatively large, the braking force on the inboard side is reduced with respect to that on the outboard side. As an alternative to brake force reduction, it is possible to increase the braking force on the side opposite to that wherein reduction would be implemented. Parameters which are used to weight the control are steering angle acceleration, which speed, and vehicle deceleration.

摘要： A vehicle turning behavior control system is mounted in an automotive vehicle having an anti-skid braking system. The control system has an electronic control unit to which a signal representative of a vehicle turning condition is input. The control unit is arranged to establish a difference between braking forces applied respectively to inside and outside wheels (with respect to a vehicle turning direction) in accordance with the turning condition representative signal so as to develop a yaw moment between the inside and outside wheels to promote a turning of the vehicle. The control unit also functions to control the braking force applied to the outside wheel in accordance with the braking force applied to the inside wheel by the anti-skid system in a manner such that the former braking force changes in a similar pattern to the latter braking force.
