ABSTRACT:
A vehicle suspension system in which a computer controls damping and spring forces to optimize ride and handling characteristics under a wide range of driving conditions. A controllable shock absorber connected between the wheel and frame of the vehicle includes a hydraulic sensor which provides signals to the computer which are representative of the position of the piston within the shock absorber. The computer utilizes these position signals to control compression and rebound hydraulic pressure regulators by continuously computing, utilizing programmed algorithms, compression and rebound damping forces that will yield the desired ride and handling characteristics. An air spring may be connected with the shock absorber for compression and rebound along the same axis. Pressure sensors and air pressure inlet and outlet valves are connected to the computer for adjusting the pressure within the air spring to provide the desired spring rate.
