US Patent 8086371 Control device for a wheel suspension system

In a control device for controlling a variable element of a wheel suspension system, the variable suspension element associated with one of the wheels is controlled at least according to an output of a sensor associated with a different one of the wheels. The output of the sensor may include a sprung mass speed of a vehicle part associated with each wheel. The variable suspension element may include a variable damping force damper or a variable spring constant spring. Thereby, an undesired response of a vehicle body can be avoided even when a vehicle is subjected to an uneven distribution of wheel loads such as when the vehicle is traveling over a slanted road surface or making a turn.
