摘要： A suspension control system can precisely control the damping characteristics of vehicular suspension for successfully and satisfactorily providing anti-dive and anti-rebound feature. The suspension control system is adapted to detect vehicle deceleration on the basis of a variation of a vehicle speed and to compare the vehicle speed with a predetermined vehicle speed criteria across which damping characteristics of the vehicular suspension vary between a harder suspension mode and a softer suspension mode. The vehicle speed criteria is variable depending upon vehicle deceleration so that the criteria becomes higher when the magnitude of deceleration is greater than a predetermined level. By hardening the suspension at an earlier timing during relatively abrupt deceleration of the vehicle, the magnitude of nose dive is reduced and the magnitude of rebounding motion after nose-dive can be reduced. This assures riding comfort by reducing the magnitude of pitching behavior of the vehicle front end. On the other hand, by providing later timing for hardening the suspension while deceleration of the vehicle is relatively low, softer damping characteristics can be maintained for a longer period to assure riding comfort by successfully absorbing bounding and rebounding shock from the road surface.

摘要： A suspension control system is able to precisely adapt damping characteristics to the road condition, even when the vehicle passes over bump, manhole, hole and so forth. The suspension control system includes a road sensor which produces a road condition indicative signal. A controller is adapted to recognize bump, manhole, hole and so forth which causes temporary bounding and rebounding motion for the vehicle, on the basis of the road condition indicative signal from the road sensor. The controller produces a control signal to harden damping characteristics of suspension when bump, manhole, hole and so forth is detected with a given delay time. The delay time for changing damping characteristics is different at the front and rear suspension from each other so that each of the front and rear suspension can be stiffened at a good timing.

摘要： An actively controlled suspension system employs a lateral acceleration sensor for monitoring lateral acceleration exerted on the vehicular body. The lateral acceleration is shifted frontwardly from a gravity center of the vehicle body at the neutral position or non-rolling condition. The magnitude of frontward offset of the lateral acceleration sensor is so selected as to cancel influence of phase delay when the lateral acceleration sensor is oriented at the position of the neutral gravity sensor.

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： A vehicle axle suspension system including wheel support members for rotatably supporting road wheels, a suspension member for supporting the road wheel support members for vertical swinging movement, and elastic suspension elements. The elastic suspension elements include a pair of front elastic suspension elements provided at different suspension points in front of the road wheel support members for elastically mounting the suspension member to the vehicle and a pair of rear elastic suspension elements provided at different suspension points behind the road wheel support members for elastically mounting the suspension member to the vehicle. The elastic suspension elements are positioned to provide an understeer characteristic when a lateral force acts on a suspension roll center determined by suspension geometry to rotate the suspension member around a virtual roll axis extending through an elastic center of the front elastic suspension elements and an elastic center of the rear elastic suspension elements.

摘要： An active suspension system is provided which includes hydraulic cylinders for suppressing rolling motion of a vehicle body. The system is responsive to lateral acceleration acting on the vehicle body to provide a control signal for supplying hydraulic pressure to the cylinders for anti-rolling control. The control signal includes first and second pressure control signals. The first pressure control signal commands supply of hydraulic pressure for providing an anti-rolling moment, while the second pressure control signal commands supply of hydraulic pressure for supporting a portion of the static load of the vehicle body to maintain the vehicle body at a target height level. The system is further responsive to increase in lateral acceleration to modify the second pressure control signal to reduce the hydraulic pressure for supporting the portion of static load, thereby compensating for forces acting to raise the vehicle body caused by the anti-rolling control for establishing a constant vehicular height level irrespective of variation in the lateral acceleration acting on the vehicle body.
