The controller may be configured to determine a target tilt angle, receive the tilt signal, receive the roll signal, and send a command to tilt the blade toward the target tilt angle, the command based on the tilt signal, the roll signal, and the target tilt angle.

Abstract: A head-mounted augmented reality device for an operator of a work machine is presented. The augmented reality device comprises a display component configured to generate and display an augmented reality overlay while providing the operator with a substantially unobstructed view. The augmented reality device also comprises a field of view component configured to detect an object within a field of view of the operator. The augmented reality device also comprises a wireless communication component configured to communicate with at least one information source. The augmented reality device also comprises a processing component configured to receive an indication from the at least one information source, and display the indication in association with the detected object.

Abstract: A work vehicle may include a chassis, a ground-engaging blade, a sensor, and a controller. The ground-engaging blade may be movably connected to the chassis via a linkage configured to allow the blade to be raised or lowered relative to the chassis. The sensor may be connected to the chassis at a fixed relative position to the chassis and configured to provide a pitch signal indicative of a rotational velocity in a pitch direction. The controller may be configured to receive the pitch signal and send a command to raise or lower the blade, the command based on a first gain and the pitch signal when the pitch signal indicates a rotational velocity in a first direction and based on a second gain and the pitch signal when the pitch signal indicates a rotational velocity in a second direction.

The blade may be movably connected to the chassis via a linkage assembly configured to allow the blade to be raised and lowered relative to the chassis. The sensor assembly may be configured to provide a chassis inclination signal indicative of an angle of the chassis relative to the direction of gravity and a blade inclination signal indicative of an angle of the blade relative to one of the chassis and the direction of gravity. The controller may be configured to receive the chassis and blade inclination signals, determine a target grade, determine a distance error based on the signals indicative of a distance between the blade and the target grade, and send a command to move the blade toward the target grade based on the distance error.

Abstract: The present disclosure provides a method of controlling movement of a reference point on an end effector of a machine, where the machine includes a controller, a first control mechanism, and a second control mechanism. The method includes initiating a movement of the reference point to a desired location with the first control mechanism. The method also includes determining an actual position of the reference point and communicating the actual position of the reference point to the controller. A second control mechanism controls the movement of the reference point to the desired location.
