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.

[ What is claimed is:] [1.] An active cab suspension system for a work vehicle, the work vehicle including a chassis, an operator's cab disposed above the chassis, and another vehicle system having a parameter related to a force applied to the chassis which causes vibrations of the chassis which are transmitted to the cab, the active cab suspension system comprising:at least one active vibration isolator mounted at a location between the cab and the chassis and responsive to a control signal to control movement of the cab relative to the chassis;a communication interface coupled to the another vehicle system; andcontrol circuit coupled to the isolator and the communication interface, the control circuit configured to receive the parameter of the another vehicle system from the communication interface, to generate the control signal at least partly in response to the parameter, and to apply the control signal to the active vibration isolator to attenuate transmission of vibrations from the chassis to the cab, the vibrations caused by the force acting on the chassis, wherein frequency vibration isolation is provided between the chassis and the cab.
