Abstract: A system for controlling an earth moving machine may comprise: a speed sensor configured to communicate a speed signal indicative of a speed of the machine; an operator bucket lift command input configured to communicate an operator-input bucket lift command; and a controller configured to: receive the speed signal and the operator-input bucket lift command; determine a torque of the machine; using the speed signal and the determined torque, determine a controller-generated bucket lift command; and provide a bucket lift command which is the larger of the operator-input bucket lift command and the controller-generated bucket lift command.

Abstract: A control system for a machine includes a machine body, a linkage assembly, an implement coupled to the machine body via the linkage assembly, an operation console remote from the machine, and a controller in communication with the operation console. The controller is configured to receive one or more signals from the operation console in order to operate the machine in a remote control mode and define a dig region and a dump region. The controller is also configured to operate the machine in an autonomous mode to dig material from the dig region and dump the material to the dump region.

Abstract: In a mobile equipment with an articulated front portion having a worktool, a fisheye camera with a wide field of view, containing the front portion, is often mounted in a fixed direction on a rear portion of the mobile equipment. Thus, when the front portion moves (e.g., rotates) relative to the rear portion, a view around the front portion may be compromised due to inherent cropping in fisheye-distortion correction. Digital panning of panoramic video is disclosed that rotates a projection surface, in accordance with movement of the front portion, and generates a projected video on the projection surface, utilizing information that may have otherwise been cropped, to expand the visible area around the worktool. The digital panning in the projected video may mimic an operator turning their head to look down the longitudinal axis of the front portion while using the worktool.

Abstract: During operation of a machine, an understanding of terrain features is critical. Accordingly, disclosed embodiments augment a video stream, captured by a camera mounted on the machine, with terrain information. In particular, an overlay is generated on at least one image frame. The overlay, which may comprise one or more semi-transparent bands, may cyclically recede from a foreground to a background of the image frame(s), cyclically advance from a background to a foreground of the image frame(s), or cyclically move horizontally across the image frame(s). The overlay may be colorized to illustrate the height of the terrain underneath the overlay.

Abstract: A method for retrofitting a plurality of position sensors on a machine includes installing the plurality of position sensors on the machine, wherein the position sensors include at least two inertial measurement units (IMUs). The method further includes calibrating orientation of the IMUs, obtaining measurements from the IMUs, determining relative differences between the measurements obtained from the IMUs, and processing the relative differences using a Kalman filter procedure to determine positional data of the machine.
