Abstract: The state and stability of a machine and a threshold value for an acceptable level of the stability of the machine are determined based on different potential machine states or operations. Sensor inputs including machine speed and whether the machine is in a coasting mode, lift height of a payload, an articulation angle of the machine, a pitch angle, and a roll angle of the machine are used to generate a model for estimating a time series of values for the degree of stability of the machine by solving a physics-based equation or retrieving data from a database.

Abstract: A method for determining implement load characteristics of a load carrying mobile machine includes receiving at least pressure data and position data associated with a payload received by the implement. The method also includes determining a locational value associated with the payload within the implement. The method further includes updating the locational value based on movement of the payload in the implement, the updated locational value being based at least on the pressure data, the position data, and predetermined physical parameters of the machine. The method further includes using the updated locational value to determine operational parameters of the machine.

Abstract: A wheel loader machine includes a bucket configured to hold a predetermined load of a granular or powder material, a hydraulic system having an electro-hydraulic actuator to move the bucket over tilt angles and to shake the bucket, a hydraulic sensor configured to detect hydraulic pressure, an interface configured to receive input parameters and to output status information of the bucket, and a controller. The input parameters including a target weight of the granular or powder material. The status information including weight of the granular or powder material in the bucket determined using the detected hydraulic pressure. The controller configured to control the hydraulic system to tilt the bucket to a predetermined tilt angle and to shake the bucket in accordance with an agitation pattern until the weight of the granular or powder in the bucket is at or below the target weight of the granular or powder material.

Abstract: A controller may obtain initial sensing data to determine an estimated weight associated with each initial load of one or more initial loads of material carried by an implement. The controller may identify an estimated weigh accuracy metric associated with each initial load and an estimated weight accuracy metric associated with a final load to be carried by the implement. The controller may determine a target weight for the final load based on the estimated weights of the one or more initial loads, the estimated weight accuracy metrics of the one or more initial loads, or the estimated weight accuracy metric associated with the final load. The controller may obtain final sensing data to determine an estimated weight associated with the final load and may cause the implement to perform one or more actions based on the estimated weight of the final load and the target weight.

Abstract: A system for assisting remote operation of a work machine may include a work machine and remote operations equipment arranged on the work machine. The remote operations equipment may be configured to capture information about the environment of the work machine and transmit the information to a remote control station. The system may also include a remote control station configured to display images of the environment of the work machine. The system may also include an operator assist module configured for augmenting the information with a feature delineator.
