Patent ID: 7222444

Claim:
A work vehicle comprising: a frame; a boom having a first boom end and a second boom end, the first boom end pivotally attached to the frame; a dipperstick having a first dipperstick end and a second dipperstick end, the first dipperstick end pivotally attached to the second boom end; a tool pivotally attached to the second dipperstick end, the tool being adapted to perform a work function; a tool actuator adapted to controllably pivot the tool about the second dipperstick end; a boom actuator adapted to controllably pivot the boom about the frame; a dipperstick actuator adapted to controllably pivot the dipperstick about the second boom end; a controller in communication with the tool actuator and at least one of the boom actuator and the dipperstick actuator; a tool command input device in communication with the controller, the tool command input device adapted to generate a first signal upon a manipulation of the tool command input device corresponding to a desired tool movement; and a tilt sensor attached to the tool, the tilt sensor detecting an inclination of the tool with respect to the earth and generating a corresponding second signal indicative of the inclination, the controller being capable of receiving the first signal and generating first tool control signals controlling at least one of the tool actuator, the boom actuator and the dipperstick actuator, the controller capable of receiving the second signal and generating second tool control signals controlling the at least one of the tool actuator, the boom actuator and the dipperstick actuator.
