ABSTRACT:
A force actuator (11) is connected between a vehicle body (15) and each vehicle wheel (16). A position sensor (66) senses displacement between the vehicle body and each vehicle wheel and provides a position signal (67) indicative thereof. An acceleration sensor (60) senses vertical inertial acceleration of the vehicle body relative to ground at each vehicle wheel and provides an acceleration signal (61) indicative of vertical inertial acceleration of the vehicle body at each vehicle wheel. A controller (70) including a digital signal processor (80) determines a velocity signal based on each acceleration signal. The controller determines a plurality of modal forces including heave, pitch, and roll modal forces which act on the vehicle body. The plurality of modal forces vary as a function of the position and velocity signals at the vehicle wheels. A force actuator control signal (94) at each vehicle wheel is produced which varies as a function of the plurality of modal forces. A drive circuit (95) processes the force actuator signal at each wheel and applies the processed force actuator control signal (96) at each vehicle wheel to the associated force actuator.
