Abstract
A method for reducing a torque load associated with an implement includes determining a speed associated with a power source, wherein the power source is configured to provide power to a hydraulic pump, determining a position associated with an implement system, and limiting a flow associated with the hydraulic pump based on the speed associated with the power source and the position associated with the implement system.
Claims18
A method for reducing a torque load associated with an implement, the method comprising:
- determining a speed associated with a power source, wherein the power source is configured to provide power to a hydraulic pump;
- determining a position associated with an implement system;
- and
- limiting a flow associated with the hydraulic pump based on the speed associated with the power source and the position associated with the implement system,
- wherein the limiting occurs when the speed associated with the power source falls below a predetermined threshold speed and the position associated with the implement system falls within a predetermined positional proximity of a stop point associated with the implement system.
A system for reducing a torque load associated with an implement, the system comprising:
- a controller communicatively connected to a power source, a first sensor configured to sense a speed associated with the power source, and a second sensor configured to sense a position of an implement system, wherein the power source is operatively connected to a hydraulic pump and configured to provide power to the hydraulic pump, and wherein the controller is configured to
- determine the speed associated with the power source based on input from the first sensor,
- determine the position associated with the implement system based on input from the second sensor,
- generate a signal based on the speed associated with the power source and the position associated with the implement system, wherein the signal affects a flow of fluid associated with the hydraulic pump;
- and
- affect the flow of fluid when the speed associated with the power source falls below a predetermined threshold speed and the position associated with the implement system falls within a predetermined positional proximity of a stop point.
A method of limiting the motion of a hydraulic cylinder on a machine, the method comprising:
- sensing a speed associated with a power source, wherein the power source is related to a machine and configured to drive a hydraulic pump associated with the machine;
- sensing a position associated with an implement system, wherein the implement system is associated with the machine, a hydraulic cylinder, and the hydraulic pump;
- receiving a command to provide a flow of fluid from the hydraulic pump to the implement system to impart motion to the implement system;
- and
- reducing the flow of fluid from the hydraulic pump, resulting in a reduced velocity of the implement system, when the speed associated with the power source falls below a power source speed threshold and the position associated with the system falls within a predetermined positional proximity of a stop point associated with the implement system.
