  • Publication number: 20190301138
    Abstract: An excavator operating cycle is detected, and a load sensor senses a physical characteristic of a load moved during the operating cycle. The location where the load is moved to is also sensed. An amount of material moved over a set of operating cycles is determined, and an action signal is generated to control the excavator based upon the calculated amount of material.

  • Patent number: 9938689
    Abstract: A coordinated control method and system for a work vehicle having a primary implement and a secondary implement and one or more controllers. The controller(s) receive a primary implement position input, which is used to generate a primary implement control command to drive one or more primary actuators to position the primary implement. The controller(s) generate a secondary implement control command that is coordinated with the primary implement position input to drive one or more secondary actuators to position the secondary implement in a relative orientation with respect to an orientation of the primary implement resulting from the primary implement control command.
