Abstract:
1. A control device for controlling a variable element of a wheel suspension system, comprising: a variable suspension element having a variable property interposed between each wheel and an associated part of a vehicle body; a sensor provided in a part of a vehicle body part adjacent to each wheel for detecting a corresponding dynamic state variable of the vehicle body; a control unit for controlling the variable suspension element associated with one of the wheels at least according to an output of the sensor associated with a different one of the wheels; and a base value computing unit that computes a target damping force base value and a correction value computing unit that computes a correction value for a vehicle part corresponding to one of the wheels according to a difference between a vertical speed of the vehicle part corresponding to the one wheel and a vertical speed of the vehicle part corresponding to a different one of the wheels, a target damping force for the vehicle part corresponding to the one wheel being determined from the target damping force base value and the correction value, wherein the dynamic state variable comprises a vertical movement variable of a vehicle body part associated with each wheel, and the control unit controls the variable suspension element in such a manner that a difference between the vertical movement variable of the vehicle body part associated with one of the wheels and the vertical movement variable of the vehicle body part associated with a different one of the wheels may be minimized, and wherein the variable suspension element provides a variable damping force.
