Abstract
An apparatus and method for controlling variation in the pitch of an agricultural vehicle, where the apparatus includes a controller that controls a position of an implement attached to the agricultural vehicle, and a first valve that is coupled to, and receives a first control signal from, the controller. The apparatus further includes a suspension cylinder having a first chamber that is hydraulically coupled to the first valve. The first control signal provided from the controller is functionally related to a first additional control signal provided by the controller, and the first additional control signal is used to determine the position of the implement.
Claims20
An apparatus for controlling variation in the pitch of an agricultural vehicle, the apparatus comprising:
- a controller that controls a position of an implement attached to the agricultural vehicle;
- a first valve that is coupled to, and receives a first control signal from, the controller;
- and
- a vehicle suspension cylinder having a first chamber that is hydraulically coupled to the first valve;
- wherein the first control signal provided from the controller is functionally related to a first additional control signal provided by the controller, the first additional control signal being used to determine the position of the implement.
An apparatus for controlling variation in the pitch of a vehicle, the apparatus comprising:
- a control means for controlling a position of a device coupled to a rear of the vehicle;
- a first suspension device for controlling the suspension of a front of the vehicle;
- and
- a first damping device for controlling a damping of the first suspension device, the first damping device being coupled to the first suspension device and to the control means;
- wherein the first damping device controls the damping based upon a first control signal that is proportionally related to an additional control signal provided by the control means for controlling the position of the device.
A method of controlling variation in the pitch of an agricultural vehicle, the method comprising:
- providing a controller capable of controlling the positioning of an implement attached to the agricultural vehicle;
- providing a vehicle suspension system on the agricultural vehicle that includes a first suspension device and a first damping device;
- generating a first position control signal to produce a change in the positioning of the implement;
- and
- generating a first suspension control signal to produce a change in operation of the first damping device,
- wherein the first suspension control signal is functionally related to the first position control signal.
