Abstract
A system and method for determining the relative position of a header with respect to a chassis of a self-propelled agricultural harvester. Single or dual axis inclinometers are secured to the header and the chassis respectively and signals generated in combination with a stored relationship to header position are used to determine the header position, whether that be the pitch and/or the roll degrees of freedom.
Claims10
A header position sensing system comprising:
- a first inclinometer mounted relative to a chassis of a self-propelled agricultural harvester;
- and
- a second inclinometer mounted relative to a header which is mounted to a front end of a feederhouse of the harvester;
- and
- an electronic control unit in communication with the first inclinometer and the second inclinometer and configured to receive a first signal from the first inclinometer and a second signal from the second inclinometer, wherein the electronic control unit calculates a position of the header with respect to the chassis using the first signal and the second signal.
A method of determining the relative position of a header with respect to a chassis of a self-propelled agricultural harvester to which the header is attached, the method comprising:
- sensing, using a first inclinometer mounted relative to a chassis, an angle of the chassis with respect to gravity;
- sensing, using a second inclinometer mounted relative to a header, an angle of the header with respect to gravity;
- receiving, using an electronic control unit, a first signal from the first inclinometer and a second signal from the second inclinometer;
- and
- calculating, using the electronic control unit, the position of the header with respect to the chassis using the first signal and the second signal.
