BLADE TILT STEERING USING GLOBAL ANGLE
A machine can include a frame, a blade coupled to the frame and configured to push a load, an inertial measurement unit (IMU) associated with the blade and configured to indicate a tilt of the blade relative to an absolute global frame of reference, and a controller configured to: receive steering c...

| description | A machine can include a frame, a blade coupled to the frame and configured to push a load, an inertial measurement unit (IMU) associated with the blade and configured to indicate a tilt of the blade relative to an absolute global frame of reference, and a controller configured to: receive steering commands; determine, based on the steering commands and the load, a desired blade tilt steering angle relative to the absolute global frame of reference; cause the blade to be tilted to the desired blade tilt steering angle; determine, based on information from the IMU, that an actual blade tilt angle is different from the desired blade tilt steering angle; cause, based on determining that the actual blade tilt angle is different from the desired blade tilt steering angle, the blade to be tilted according to a corrected blade tilt angle, wherein, when the actual blade tilt angle is offset, in a first direction, from the desired blade tilt steering angle, the corrected blade tilt angle is to tilt the blade in a second direction, opposite the first direction, and wherein the corrected blade tilt angle causes the blade to be tilted, relative to the absolute global frame of reference, to match the desired blade tilt steering angle. |
