  • 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.

  • Publication number: 20230244246
    Abstract: Systems and methods can implement collaborative path planning of mobile machines in an unstructured area. The systems and methods can involve receiving, at an area controller at a worksite, a list of mobile machines that are in the unstructured area, responsive to identification of the mobile machine entering (including just about to enter) the unstructured area from a structured area. The systems and methods can also involve receiving, at the area controller, location information including a location at which the mobile machine is to perform a task, when the mobile machine enters the unstructured area; and coordinating, via the area controller, with the mobile machines on the list of mobile machines, for the one mobile machine to traverse a locally determined path to the location at which the mobile machine is to perform the task without interfering with locally determined paths of the other mobile machines in the unstructured area.

  • Patent number: 9560692
    Abstract: A system for controlling a machine may include a remote control (RC) input device configured to remotely initiate a RC enabled mode on the machine. The RC input device may subsequently establish a communication link with the machine when no other RC input device currently has a communication link with the machine. The RC input device may transition the machine to a RC reserved mode in which the machine is reserved for control by the RC input device, and transition a mode of control for the machine to a RC active mode from the RC reserved mode. The RC input device may selectively control the machine when in the RC active mode. The RC input device may also transition the mode of control for the machine to an autonomous mode from the RC active mode.

  • Patent number: 9244464
    Abstract: A control system is disclosed for use with a machine at a worksite. The control system may have an offboard controller. The offboard controller may be configured to receive information regarding a berm at the worksite, determine starting and ending points spaced apart along an edge of the berm based on the information, and determine a maximum orthogonal distance from a virtual line extending between the starting and ending points to the edge of the berm. The offboard controller may be further configured to selectively validate the starting and ending points based on the maximum orthogonal distance, and to designate a center of the virtual line between validated starting and ending points as a dump target.
