Abstract
A system has a hydraulic circuit configured to control a position of an attachment of the system and a control system configured to perform operations that include receiving an input indicative of a center of gravity of the attachment and controlling a flow rate of fluid directed through the hydraulic circuit based on the center of gravity.
Claims15
A system, comprising:
- a hydraulic circuit configured to control a position of at least a portion of an attachment of the system;
- and
- a control system configured to perform operations comprising:
- receiving an input indicative of a center of gravity of the attachment;
- and
- controlling a flow rate of fluid directed through the hydraulic circuit based on the center of gravity,
- wherein the control system comprises a user interface, and the control system is configured to receive the input indicative of the center of gravity via a user input into the user interface.
A tangible, non-transitory, computer readable medium comprising instructions that, when executed by processing circuitry, are configured to cause the processing circuitry to perform operations comprising:
- receiving an input indicative of a center of gravity of an attachment coupled to a work vehicle of a system;
- determining a threshold flow rate of fluid through a hydraulic circuit of the system based on the center of gravity of the attachment;
- controlling the hydraulic circuit of the system to direct the fluid through the hydraulic circuit at a flow rate below the threshold flow rate to control movement of at least a portion of the attachment;
- receiving an additional input indicative of a target flow rate of the fluid through the hydraulic circuit;
- determining whether the target flow rate is below the threshold flow rate;
- and
- controlling the hydraulic circuit to direct the fluid through the hydraulic circuit at the target flow rate in response to a determination that the target flow rate is below the threshold flow rate.
An system, comprising:
- a hydraulic circuit configured to control a position of at least a portion of an attachment of the system;
- and
- a control system configured to perform operations comprising:
- receiving an input indicative of a center of gravity of the attachment;
- determining a threshold speed, a threshold acceleration, or both, of at least the portion of the attachment;
- controlling the hydraulic circuit to direct fluid through the hydraulic circuit to move at least the portion of the attachment at or below the threshold speed, the threshold acceleration, or both;
- receiving an additional input indicative of a target speed, a target acceleration, or both;
- comparing the target speed to the threshold speed, comparing the target acceleration to the target acceleration, or both;
- and
- controlling the hydraulic circuit to direct the fluid through the hydraulic circuit to move at least the portion of the attachment at the target speed in response to a determination that the target speed is below the threshold speed, controlling the hydraulic circuit to direct fluid through the hydraulic circuit to move at least the portion of the attachment at the target acceleration in response to a determination that the target acceleration is below the threshold acceleration, or both,
- wherein the control system is configured to control the hydraulic circuit to direct the fluid through the hydraulic circuit to move at least the portion of the attachment at an additional speed that is lower than the threshold speed in response to a determination that the target speed is above the threshold speed, to control the hydraulic circuit to direct the fluid through the hydraulic circuit to move at least the portion of the attachment at an additional acceleration that is lower than the threshold acceleration in response to a determination that the target acceleration is above the threshold acceleration, or both.
