Abstract
A vehicle suspension system includes shock absorbers with valves or damping orifices controlled by solenoids. The solenoids are connected to an electronic control unit which is activated in response to a predetermined rate of compression or extension of the shock absorber. A dash-mounted operator control and vehicle attitude sensors for sensing the load, pitch and roll of the vehicle are also connected to the electronic control unit. The electronic control unit energizes the solenoid to control the opening and closing of the valves in response to changes in the vehicle attitude and in response to signals generated by the operator control.
