Abstract: The invention concerns a method and a device for the suspension control of vehicles, in particular motorcars and commercial vehicles, with the following steps:Sensory ascertainment of the dynamic rolling condition and processing of the established rolling condition data, to generate a control signal for a semi-active damper, preferably one allocated to each wheel of the vehicle, the damping force of which is adjustable in certain situations which are dependent on the driving condition, to as small a value as possible. It is suggested that the semi-active damper, depending on the control signal and the actual value of the damper force is set in substitution for an active damper function which though desired with regard to the prevailing operating point, is not however achievable, this substitute setting being made with maximum hardness or maximum softness.

Abstract: A suspension apparatus of an automotive vehicle controls a posture of the vehicle body by controlling supply and discharge of an operating liquid to and from a cylinder unit interposed at each of the wheels between a sprung weight and an unsprung weight. The pressure within a high-pressure line for supplying the operating liquid of a high pressure to the cylinder units is released to the reservoir tank at a faster speed when a trouble occurs which cannot normally perform a control of the posture of the vehicle body and at a slower speed when an ignition switch has been turned off.

Abstract: A suspension pressure control system applies a pressure which is proportional to a current level supplied to a solenoid of a pressure control valve to a shock absorber associated with a suspension from the valve through a cut valve, which cuts off a fluid path from the pressure control valve to the shock absorber when a line pressure is below a predetermined value and communicates the fluid path when the line pressure exceeds the predetermined value. An electronic controller controls the current level to maintain an attitude of a vehicle substantially constant in spite of any change of longitudinal and lateral acceleration, which are detected by acceleration sensors. In order to prevent an abrupt or abnormal change of the pressure of the shock absorber at an initiation of the pressure control of the controller when the vehicle is parking on a slope, the controller initiates the pressure control before the cut valve communicates the fluid path.

Abstract: In order to ensure riding comfort and driving stability in an automotive suspension system, the nature of the effect of the damping force generated by the suspension system is observed. When the damping characteristics of the suspension system are too hard, resulting in amplification of vibrations in the suspension system, the damping characteristics are softened to ensure satisfactory riding comfort. Therefore, according to the present invention, an automotive suspension system has variable damping characteristics which depend on the nature of the damping force produced in response to bounding and/or rebounding motion of the vehicle so as to optimize damping characteristics to achieve both riding comfort and driving stability. In the preferred embodiment, a suspension control system uses the vibration frequency of a sprung mass and the relative speed between the sprung mass and an unsprung mass as control parameters representing the nature of damping force.

Abstract: This invention relates to hydraulic suspension systems and in particular to vehicle oleopneumatic suspension systems employing sliding pillar struts. There is provided a suspension system for a vehicle comprising a plurality of suspension struts, each mounted between a vehicle body and a wheel assembly, each including a cylinder having a closed end and an inner bore; a piston rod slideable within the inner bore having a proximal end which terminates within the inner bore and a distal end which extends from the inner bore. Between the inner bore and the piston rod there is mounted an oil seal which seals a strut volume. A hydrostatic bearing is mounted within and vents into the strut volume. A hydraulic circuit and associated control system is adapted to control flow of hydraulic fluid between the strut volume and a reservoir, thereby providing control of at least the time-averaged axial position of the piston rod relative to its corresponding inner bore.

Abstract: The object of the inventional system is the so-called "modal" variant of the skyhook damping. The advantage of this variant over the local version is essentially constituted by enabling an individual damping of the eigenoscillation forms. Moreover, a definitive roll or sway moment distribution can be adjusted. For that purpose there are signals determined which represent the local vehicle body movements at selected points of the vehicle body. Basing on these signals, the heave, roll and pitch movements are inferred. These movements are differently weighted depending on travel maneuvers. By actuation of the damper systems dependent on the weighted heave, roll and pitch movements a specific influencing of certain components of the body movement is possible.
