A method for controlling engagement of a clutch in a work machine, comprising:
- determining a relative speed of the clutch of the work machine;
- selectively adjusting an actuation pressure applied to the clutch based at least in part on the clutch relative speed.
A method for controlling engagement of a clutch in a work machine, comprising:
- determining a transmission ratio of the work machine;
- and
- selectively adjusting an actuation pressure applied to the clutch based at least in part on the transmission relative speed.
A method for controlling engagement of a clutch in a work machine, comprising:
- applying a first set of actuation pressures to the clutch for a majority of clutch engagement;
- and
- applying a second set of actuation pressures to the clutch after the first set, the second set of clutch actuation pressures being less than a maximum clutch actuation pressure of the first set.
A system for controlling the engagement of at least one clutch in a transmission, the system comprising:
- at least one electronic control unit configured to control engagement of the at least one clutch by:
- determining a relative speed of the transmission;
- and
- selectively adjusting an actuation pressure applied to the at least one clutch based at least in part on the transmission relative speed.
