  • Patent number: 11868114
    Abstract: A controller may configure the machine to operate in a plurality of modes including a manned control mode, a remote control mode, and an autonomous control mode. The controller may receive a request to cause the machine to perform an action; and determine a requested mode of operation of the machine associated with the request. The requested mode of operation may be one of the plurality of modes. The controller may selectively deny the request or enable the machine to perform the action based on a priority assigned to a current mode of operation of the machine and a priority assigned to the requested mode of operation.
    Type: Grant

  • Patent number: 11124942
    Abstract: A system for controlling a ground engaging work implement includes a machine position sensor, a work surface position sensor, a work implement position sensor, and a controller. The controller determines the position of the machine, determines the topography of the work surface, determines a location of a pre-task trigger location adjacent the task start location, and determine a position of the lowest surface of the ground engaging work implement. The controller generates traverse signals to propel the machine from the task end location towards the task start location, generate work implement height signals to maintain the lowest surface of the ground engaging work implement at or above the traversing threshold height as the machine travels from the task end location towards the task start location, and generate work implement lowering signals to lower the work implement to the pre-task threshold height after the machine passes the pre-task trigger location.

  • Publication number: 20210222406
    Abstract: A guide system for planning missions of autonomous or semi-autonomous material displacement machines includes an operator interface and at least one computer coupled with the operator interface. The at least one computer is structured to receive working elevation information associated with missions executed by machines and indicative of working elevation parameters dependent upon disposition of a material displaced by the machines. The guide system is further structured to receive surrounding terrain information and compare the working elevation parameters to a surrounding elevation parameter. The guide system produces elevation variance alerts based on the comparison, and displays the elevation variance alerts in an operator-perceptible form such as graphically on a display in an operator interface.
