Patent Images
1. A method for controlling a differential lock of a work vehicle, comprising:
- receiving at least one turn angle signal,determining if the work vehicle is oriented to travel in a generally straight direction based on the at least one turn angle signal, andif the work vehicle is so oriented, automatically commanding activation of the differential lock, wherein;
the at least one turn angle signal comprises a single articulation angle signal representative of an articulation angle between articulated front and rear sections of the work vehicle and a single steering angle signal representative of a steering angle of a ground-engaging traction element of the work vehicle, andthe determining comprises determining if the work vehicle is oriented to travel in a generally straight direction based on the articulation angle signal and the steering angle signal.
