This description provides an autonomous or semi-autonomous excavation vehicle that is capable of navigating through a dig site and carrying out an excavation routine using a system of sensors physically mounted to the excavation vehicle. The sensors collects any one or more of spatial, imaging, measurement, and location data representing the status of the excavation vehicle and its surrounding environment. Based on the collected data, the excavation vehicle executes instructions to carry out an excavation routine. The excavation vehicle is also able to carry out numerous other tasks, such as checking the volume of excavated earth in an excavation tool, and helping prepare a digital terrain model of the site as part of a process for creating the excavation routine.

A system for automatically performing an earthmoving operation may include a work vehicle having an implement that is articulable by the work vehicle over a stroke length, a user interface, and a controller communicatively coupled to the user interface. The controller may be configured to receive an operator input via the user interface associated with performing an earthmoving operation with the implement of the work vehicle according to one of a plurality of earthmoving styles. Additionally, the controller may be configured to control the operation of the work vehicle to perform the earthmoving operation with the implement within the worksite based at least in part on the one of the plurality of earthmoving styles.

A loading vehicle detects the position of a receiving relative to the loading vehicle and determines whether the receiving vehicle is to be repositioned. If so, it sends a repositioning message to the receiving vehicle and received acknowledgement that the loading vehicle has remote control of the positioning mechanisms in the receiving vehicle. a loading vehicle operator input is detected and a position control signal is sent to the receiving vehicle to reposition it relative to the loading vehicle.

A perception-based alignment system can assist in aligning a loading machine with a material receptacle. The perception-based alignment system can be associated with a visual sensor network that can capture an image of the material receptacle. A fiducial marker is associated with the material receptacle. In an aspect, the perception-based alignment system can record an alignment data record of a loading operation and associate the alignment data record with the fiducial marker and, in another aspect, the perception-based alignment system can retrieve and execute the alignment data record to assist with a subsequent loading operation.

A system for coupling an implement to a work vehicle includes a controller comprising a memory and a processor, wherein the controller is configured to receive a first signal indicative of a distance between a protrusion of a connector assembly of an arm of the work vehicle and a receiver assembly of the implement. While the first signal is less than a first threshold, the controller is configured to instruct a first actuator to rotate the connector assembly of the work vehicle, instruct a drive system to move the work vehicle toward the implement, instruct a second actuator to lift the arm of the work vehicle, or a combination thereof, such that the protrusion of the connector assembly engages a recess in the receiver assembly.

A shovel includes processing circuitry configured to predict the motion of the shovel and, in response to predicting that the shovel next performs a predetermined motion, issue an alert indicating that the predetermined motion is to be performed to an area surrounding the shovel before the start of the predetermined motion.

A sensor-augmented system for optimizing the loading parameters of a work machine to engage a pile. The system comprises a sensor coupled with the work machine where the sensor is configured to collect image data of the pile in a field of view of the sensor; a sensor processing unit communicatively coupled with the sensor where the sensor processing unit is configured to calculate a volume estimation of the pile based on the image data; and a vehicle control unit communicatively coupled with the sensor processing unit to modify a loading parameter of the work machine in response to a calculated predictive load based on the volume estimation and stored data to identify material type of the pile.

A work vehicle includes a frame; an implement; a linkage assembly mounting the implement to the frame; a linkage actuator coupled to the linkage assembly and the frame and configured to reposition the linkage assembly relative to the frame; a sensor configured to generate sensor position data associated with at least one of the linkage assembly and the linkage actuator representing a linkage position; an operator interface configured to receive operator input from an operator associated with the linkage actuator representing a velocity request; and an electronic control system having processing and memory architecture operatively coupled to the sensor, operator interface, and linkage actuator. The electronic control system is configured to generate an actuator command for the linkage actuator based on the velocity request and the linkage position that, upon execution, results in a constant velocity of the implement for the operator input regardless of the linkage position.

A mobile work machine includes a frame, a material loading system having a material receiving area configured to receive material and an actuator configured to control the material loading system to move the material receiving area relative to the frame, and a control system configured to receive an indication of a detected object, determine a location of the object relative to the material loading system, and generate a control signal that controls the mobile work machine based on the determined location.
