US 2026/0226713 A1 · Method Of Controlling A Powertrain

Abstract

A method of controlling a torque output of a powertrain of a work vehicle in response to a demanded torque output for the powertrain is provided. The method comprises determining a change in the torque output of the powertrain in response to the demanded torque output based on a torque rate of change constraint. The method also comprises determining a change in the power output of the powertrain based on the determined change in the torque output of the powertrain. If the determined change in the power output of the powertrain exceeds a power change threshold of the powertrain, the determined change in the torque output of the powertrain is updated based on a power rate of change constraint of the powertrain. The torque output of the powertrain is controlled based on the determined change in the torque output.
