ABSTRACT:
An active suspension system for a work vehicle is disclosed herein. The system includes at least one active vibration isolator mounted between the chassis and cab of the vehicle. The isolator moves the cab relative to the chassis in response to a control signal generated by a control circuit. The control circuit communicates to a second vehicle system via a communication interface. The communicated data includes a parameter of the second vehicle system related to a force applied to the vehicle during operation of the second vehicle system. The control signal is generated at least partly in response to the parameter so as to minimize the vibration on the cab caused by operation of the second vehicle system. Cab movement may be disabled when ground speed of the vehicle is below a predetermined speed threshold or when an operator presence sensor detects that the operator is not present.
