Abstract
An apparatus controls a damper connectable between a vehicle body and a vehicle wheel. A position sensor senses the amount of angular displacement between the vehicle body and the vehicle wheel and provides a position signal indicative thereof. An acceleration sensor senses the amount of vertical acceleration of the vehicle body relative to ground and provides a vertical acceleration signal indicative thereof. Another acceleration sensor senses the amount of lateral acceleration of the vehicle body and provides a lateral acceleration signal indicative thereof. A processor processes the position signal, the vertical acceleration signal, and the lateral acceleration signal to provide a control signal which continuously varies as a function of (i) a summation of the position signal and the vertical acceleration signal, and (ii) a summation of the position signal and the lateral acceleration signal. Preferably, the processor is a digital signal processor. A drive circuit applies the control signal from the processor to the damper to control the damping rate of the damper.
