Abstract: A vehicle includes a transmission that performs a method of operating a clutch of a vehicle. The vehicle includes the clutch, an actuator device and a processor. The actuator device includes a piston movable to operate the clutch. The processor is configured to receive a pressure signal indicative of a selected fluid pressure for operating the clutch, determine a position for the piston in the actuator device from the pressure signal, and move the piston to the position to operate the clutch at the selected fluid pressure.

Abstract: Vehicles and related systems and methods are provided for round-robin air purging of disengaged clutches. One method involves obtaining a plurality of weighting factors associated with respective ones of a plurality of clutches of a vehicle transmission, obtaining an exhaustion time associated with each respective clutch, determining a respective priority metric associated with the each respective clutch based at least in part on the exhaustion time associated with the respective clutch and the respective weighting factor associated with the respective clutch, determining a highest priority clutch of the plurality of clutches based at least in part on the respective priority metrics associated with the respective clutches of the plurality of clutches, and operating one or more valves in accordance with a pulse command to pulse the highest priority clutch with a commanded pressure for a commanded period of time.

Abstract: Systems and methods are provided for controlling a transmission associated with a vehicle. The method includes receiving a neutral range selection for the transmission, and receiving a temperature and a pressure of a lubricant associated with the transmission. The method includes receiving a speed of an input shaft associated with the transmission, and determining, by a processor, based on the temperature and the speed of the input shaft, a pressure threshold value for the lubricant. The method includes outputting, by the processor, one or more control signals to command the transmission to a one clutch neutral state in which one clutch of a plurality of clutches associated with the transmission is engaged based on a comparison of the pressure threshold value to the pressure of the lubricant.
