Temperature-based clutch protection from centrifugal head pressure inhibiting clutch disengagement

A tangible, non-transitory, machine-readable-medium, comprising machine-readable instructions to cause a processor to:

• receive a command to disengage a clutch of a work vehicle, wherein the clutch comprises a centrifugal head internal relief port;
• determine an engine speed of the work vehicle;
• determine a temperature of hydraulic fluid in the clutch;
• determine a magnitude for a time to limit acceleration of the work vehicle based on the engine speed and the temperature, wherein limiting the acceleration of the work vehicle at the magnitude for the time causes the clutch to rotate at a rotational speed less than a centrifugal self-engagement speed;
• command the clutch to disengage;
• and
• limit the acceleration of the work vehicle based on the magnitude for the time determined using a hydrostatic unit of a transmission of the work vehicle configured to control a speed of the work vehicle, wherein limiting the acceleration of the work vehicle at the magnitude for the time causes the clutch to rotate at the rotational speed less than the centrifugal self-engagement speed, wherein rotating the clutch at the rotational speed less than the centrifugal self-engagement speed enables the centrifugal head internal relief port to open and the clutch to disengage.

A method for protecting a clutch of a work vehicle from centrifugal head pressure inhibiting clutch disengagement, comprising:

• receiving, via a controller, a command to disengage the clutch, wherein the clutch comprises a centrifugal head internal relief port;
• determining, via the controller, an engine speed of the work vehicle;
• determining, via the controller, a temperature of hydraulic fluid in the clutch;
• determining, via the controller, a magnitude for a time to limit acceleration of the work vehicle based on the engine speed and the temperature, wherein limiting the acceleration of the work vehicle at the magnitude for the time causes the clutch to rotate at a rotational speed less than a centrifugal self-engagement speed;
• commanding, via the controller, the clutch to disengage;
• and
• limiting, via the controller, the acceleration of the work vehicle based on the magnitude for the time determined using a hydrostatic unit of a transmission of the work vehicle configured to control a speed of the work vehicle, wherein limiting the acceleration of the work vehicle at the magnitude for the time causes the clutch to rotate at the rotational speed less than the centrifugal self-engagement speed, wherein rotating the clutch at the rotational speed less than the centrifugal self-engagement speed enables the centrifugal head internal relief port to open and the clutch to disengage.
