Control of an active suspension system for a work vehicle based upon a parameter of another vehicle system

A work vehicle, comprising:

• a chassis;
• an operator's cab disposed above the chassis;
• an active cab suspension system including at least one active vibration isolator mounted between the cab and the chassis and responsive to a control signal to control movement of the cab relative to the chassis;
• 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;
• and
• a communication interface coupled between the active cab suspension system and the another vehicle system;
• wherein the active cab suspension system further includes a control circuit coupled to the communication interface and configured to receive the parameter of the another vehicle system, 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.

An active seat suspension system for a work vehicle, the work vehicle including a chassis, an operator's seat supported by the chassis, and a second vehicle system having a parameter related to a force applied to the chassis which causes vibrations of the chassis which are transmitted to the seat, the active seat suspension system comprising:

• at least one active vibration isolator mounted at a location between the seat and the chassis and responsive to a control signal to control movement of the seat relative to the chassis;
• a communication interface coupled to the second vehicle system;
• and
• a control circuit coupled to the communication interface and the active vibration isolator, the control circuit configured to receive the parameter of the second vehicle system from the communication interface, and to generate the control signal applied to the vibration isolator at least partly in response to the parameter, wherein transmission of vibrations from the chassis to the seat is attenuated, the vibrations caused by the force acting on the chassis, wherein frequency vibration isolation is provided between the chassis and the seat.

An active cab suspension system for a work vehicle, the work vehicle including a chassis, an operator's cab disposed above the chassis, and a second vehicle system having a parameter related to ground speed of the work vehicle, 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 second vehicle system;
• and
• a control circuit coupled to the communication interface and the active vibration isolator, the control circuit configured to receive the parameter of the second vehicle system from the communication interface, to generate the control signal applied to the isolator to attenuate movement of the cab when the ground speed is above a predetermined speed threshold, and to disable cab movement when the ground speed is below the threshold.

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 about to be applied to the work vehicle, 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;
• and
• a control 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 predict the force about to be applied to the work vehicle based upon the parameter, to generate the control signal at least partly in response to the predicted force, and to apply the control signal to the active vibration isolator to attenuate movement of the cab due to the force about to be applied to the work vehicle, wherein the parameter is used as a preparatory signal.
