Abstract
A method for operating one or more sub-systems of a work machine includes generating, by an input device, a signal; determining, by a controller, a condition based on the signal, the condition indicating an impending issuance of a command for actuating the sub-systems using a hydraulic system; and raising, by the controller, an instruction to activate a hydraulic pump of the hydraulic system in response to the condition such that the hydraulic system is energized prior to actuating the sub-systems.
Claims17
A method for operating one or more sub-systems of a first work machine, the method comprising:
- sensing, by a sensor of an input device, a first distance and a second distance of a second work machine from the first work machine, wherein the second distance is sensed pursuant to the sensing of the first distance;
- generating, by the input device, one or more signals including a first signal and a second signal;
- comparing, by a controller, the second signal with the first signal to determine a difference between the second distance and the first distance to have increased beyond a threshold difference to determine a condition;
- determining, by the controller, the condition based on the one or more signals, the condition indicating an impending issuance of a command for actuating the one or more sub-systems using a hydraulic system;
- and
- raising, by the controller, an instruction to activate a hydraulic pump by powering on an electric motor of the hydraulic system in response to the condition such that the hydraulic system is energized prior to actuating the one or more sub-systems.
A system for operating one or more sub-systems of a first work machine, the system comprising:
- an input device configured to generate one or more signals, the input device including a sensor configured to:
- sense a first distance and a second distance of the second work machine with respect to the first work machine;
- and
- generate a first signal and a second signal of the one or more signals, wherein the second distance is sensed pursuant to a sensing of the first distance;
- and
- a controller communicatively coupled with the input device, the controller configured to:
- compare the second signal with the first signal to determine a difference between the second distance and the first distance to have increased beyond a threshold difference to determine a condition;
- determine the condition based on the one or more signals, the condition indicating an impending issuance of a command for actuating the one or more sub-systems using a hydraulic system;
- and
- raise an instruction to activate a hydraulic pump by powering on an electric motor of the hydraulic system in response to the condition such that the hydraulic system is energized prior to actuating the one or more sub-systems.
A first work machine, comprising:
- one or more sub-systems to perform work;
- a hydraulic system to actuate the one or more sub-systems, the hydraulic system including a hydraulic pump;
- and
- a system for operating the one or more sub-systems, the system including:
- an input device configured to generate one or more signals, the input device including a sensor configured to:
- sense a first distance and a second distance of the second work machine with respect to the first work machine;
- and
- generate a first signal and a second signal of the one or more signals, wherein the second distance is sensed pursuant to a sensing of the first distance;
- and
- a controller communicatively coupled with the input device, the controller configured to:
- compare the second signal with the first signal to determine a difference between the second distance and the first distance to have increased beyond a threshold difference to determine a condition;
- determine the condition based on the one or more signals, the condition indicating an impending issuance of a command for actuating the one or more sub-systems using the hydraulic system;
- and
- raise an instruction to activate the hydraulic pump by powering on an electric motor of the hydraulic system in response to the condition such that the hydraulic system is energized prior to actuating the one or more sub-systems.
