1. An apparatus for controlling the amount of electric current flow through a coil of an electromagnet of a damper connectable between a vehicle body and a vehicle wheel, said apparatus comprising:

  • a position sensor for sensing displacement between the vehicle body and the vehicle wheel and for providing a position signal indicative thereof;

    a first acceleration sensor for sensing vertical acceleration of the vehicle body relative to ground and for providing a vertical acceleration signal indicative thereof;

    a processor for processing said position and vertical acceleration signals to provide a continuous analog control signal which varies as a function of a summation of said position and vertical acceleration signals; and

    a drive circuit for applying said continuous analog control signal from said processor to the electromagnet of the damper to control the amount of electric current flow through the coil of the electromagnet and thereby to control operation of the damper.
