Abstract
A traction drive system for a work machine, including at least one electric motor, a transmission, and a controller. The controller is configured to select a gear ratio of the transmission depending on a change to be expected in a motor output of the at least one electric motor. The change to be expected in the motor output is conditional on a change in the gear ratio of the transmission. The change to be expected in the motor output is determined on the basis of at least one operating parameter of the work machine.
