Abstract
A system and method are provided for determining a difference in height of a dozer blade relative to a vehicle frame between a reference position wherein the dozer blade engages the ground and a calibration position wherein the at least one sensor is at a desired height relative to a laser signal plane using a laser receiver automatic find mode.
Claims20
A work vehicle, comprising:
- a vehicle frame;
- a plurality of ground engaging units for supporting the vehicle frame from a ground surface;
- a ground-engaging dozer blade movably connected to the vehicle frame by a linkage assembly configured to allow the dozer blade to articulate relative to the vehicle frame, the dozer blade including first and second ends;
- at least one support having lower and upper portions, the lower portion of the at least one support coupled to the dozer blade;
- at least one sensor configured to detect a laser signal plane emitted by a rotating laser, the at least one sensor being mounted to the upper portion of the at least one support;
- and
- a controller including a laser receiver automatic find mode configured to:
- determine a difference in height of the dozer blade relative to the vehicle frame between a reference position wherein the dozer blade engages the ground surface and a calibration position wherein the at least one sensor is at a desired height relative to the laser signal plane.
A method of controlling a work vehicle, the work vehicle including a vehicle frame, a ground-engaging dozer blade having first and second ends and being moveably connected to the vehicle frame by a linkage assembly configured to allow the dozer blade to articulate relative to the vehicle frame, at least one support having upper and lower portions, the lower portion of the at least one support coupled to the dozer blade, at least one sensor configured to detect a laser signal plane emitted by a rotating laser, the at least one sensor being mounted to the upper portion of the at least one support, and a controller, the method comprising:
- orienting the work vehicle in an intended grading direction;
- and
- automatically determining with the controller a difference in height of the dozer blade relative to the vehicle frame between a reference position wherein the dozer blade engages the ground and a calibration position wherein the at least one sensor is at a desired height relative to the laser signal plane.
