METHOD OF ROLL CALIBRATION FOR A WORK VEHICLE

A method of calibrating a roll angle associated with a work vehicle includes the steps of: positioning the vehicle on a substantially level surface in a first direction; taking a first calibration reading, by using an inertial measurement unit (IMU) to measure a roll of the vehicle while the vehicle...

Summary:A method of calibrating a roll angle associated with a work vehicle includes the steps of: positioning the vehicle on a substantially level surface in a first direction; taking a first calibration reading, by using an inertial measurement unit (IMU) to measure a roll of the vehicle while the vehicle is in a first of a sequence of calibration maneuvers in the first direction; positioning the vehicle on the substantially level surface in a second direction, generally opposite the first direction; taking a second calibration reading, by using the IMU to measure a roll of the vehicle while the vehicle is in a second of the sequence of calibration maneuvers in the second direction; and reconciling the first calibration reading and the second calibration reading to determine a calibrated roll angle of the vehicle.
