  • Patent number: 10570582
    Abstract: A machine includes a power generation system; a propulsion system; a work implement coupled to a body of the machine via a linkage that includes at least one actuator; a perception system configured to generate a signal that is indicative of a position of the machine relative to a material receptacle; and a controller operatively coupled to the perception system, the propulsion system, the power generation system, and the at least one actuator. The controller is configured to receive the signal from the perception system, determine a location of the work implement relative to the material receptacle based at least in part on the signal from the perception system, and actuate at least one of the propulsion system, the power generation system, and the at least one actuator based on the determined location of the work implement relative to the material receptacle.

  • Publication number: 20160312432
    Abstract: A method for installing a work tool for a machine is provided. The method includes detecting, at an electronic controller unit of a machine, a work tool based upon a first input signal from a sensor coupled to the electronic controller unit. The method includes determining, at the electronic controller unit, a first three-dimensional location of the work tool relative to the machine. The method includes detecting, at the electronic controller unit, an occlusion of the work tool. The method includes determining, at the electronic controller unit, a second three-dimensional location of the work tool upon the detecting of the occlusion based on the first three-dimensional location. The method includes controlling, at the electronic controller unit, a motion of the machine for installing the work tool based upon the second three-dimensional location.

  • Publication number: 20140320293
    Abstract: A method for alerting an operator during linkage overload in a machine is disclosed. The method includes calculation of operational height of a payload carrier. Fluid pressure in one of a lift cylinder assembly and a tilt cylinder assembly is sensed and weight of a payload based on the fluid pressure is calculated. Maximum payload height based on the pressure of at least one of the lift cylinder assembly and the tilt cylinder assembly, is determined Based on the maximum payload height, a threshold payload height is determined and compared with an operational height of the payload carrier. When the operational height of the payload carrier is equal to or greater than the threshold payload height, at least one of a warning generation event and limiting raising of the lift cylinder assembly occurs.
