    摘要： Basing on signals (Vi) representing the vertical movements of the vehicle body at selected points (Pi) of the body, and basing on second signals (Xarvl', Xarvr', Xarhl', Xarhr') representing the relative movements between the wheel units and the body of the vehicle, the inventional system infers selected components of movement of the vehicle body, such as heave, roll and pitch movements or the vertical movement of the body at the front and rear axles as well as the roll movement. These components of movement are weighted differently. Basing on these differently weighted components of movement, second body movements are inferred at the points where the wheel suspension systems attach to the body. By comparison of the second body movements (Vagvl, Vagvr, Vaghl, Vaghr) to the pertaining relative movements between the wheel units and the body there are actuation signals formed for the respective suspension system, in a way such that the selected components of movement can be influenced separately from one another in the sense of a reduction.

    摘要： A control method for semi-active damper (32) which oscillates in real time (at the frequency of the moving member (22) motion or higher) between a high-damping On state and a low-damping Off state wherein the On and Off damping states are selected by the driver via a driver selectable switch (60) and overridden when the absolute velocity differential across the suspended body exceeds a threshold value and the signs are opposite. Damping bands can be set to a luxury, touring, or sport mode via the driver selectable switch (60). This system provides driver selectable ride feel and yet controls excessive roll and pitch due to vehicle maneuvers, braking, and acceleration by overriding the driver selectable setting whenever the absolute velocity differential threshold setting is exceeded and the directional signs are different. When the threshold is exceeded and the signs are opposed, the null band is adjusted to a narrower setting to initiate control of the damper. This allows the null band to be set wider for normal driving, providing better isolation.

    摘要： Selectively engagable auxiliary leaf springs (38) for vertically supporting a vehicle chassis (32) on an axle assembly (22) in parallel with main suspension springs (34). Forward and rear ends (38b,38a) of the auxiliary leaf springs are pivotally attached to the vehicle chassis and the axle assembly, and pivotal movement of the forward ends (38b) is inhibited or prevented by engagement of actuator assemblies (56 or 100 or 170) to engage the axuiliary leaf springs. A control system automatically engages the actuator assemblies in response to load added to the vehicle and/or vehicle steering movement and/or rapid vehicle acceleration.
