Abstract
A method of controlling an input clutch and an output clutch, wherein the input clutch couples to a power source, the output clutch couples to a load, and the input clutch couples to the output clutch via gears, includes controlling torque of the input clutch based on a torque of the output clutch or a lookup table that controls the torque of the output clutch. The method also includes adjusting the torque of the input clutch based on a slip speed of the input clutch and a slip speed of the output clutch.

A method of controlling an input clutch and an output clutch, wherein the input clutch is configured to couple to a power source, the output clutch is configured to couple to a load, and the input clutch is coupled to the output clutch via gears, the method comprising:
- controlling torque of the input clutch based at least in part on a torque of the output clutch or a lookup table configured to control the torque of the output clutch;
- and
- adjusting the torque of the input clutch based at least in part on a slip speed of the input clutch and a slip speed of the output clutch.
A system of a work vehicle, comprising:
- a transmission comprising an input clutch and an output clutch, wherein the input clutch is configured to couple to a power source, the output clutch is configured to couple to a load, and the input clutch is coupled to the output clutch;
- a controller communicatively coupled to the input clutch and to the output clutch, wherein the controller is configured to:
- control torque of the input clutch based at least in part on a torque of the output clutch or a lookup table configured to control the torque of the output clutch;
- and
- adjust the torque of the input clutch based at least in part on a slip speed of the input clutch and a slip speed of the output clutch.
A tangible, non-transitory, machine-readable medium, comprising machine-readable instructions to:
- control torque of an input clutch based at least in part on a torque of an output clutch or a lookup table configured to control the torque of the output clutch, wherein the input clutch is configured to couple to a power source, the output clutch is configured to couple to a load, and the input clutch is coupled to the output clutch;
- and
- adjust the torque of the input clutch based at least in part on a slip speed of the input clutch and a slip speed of the output clutch.
