Abstract
A method for operating an electrified drivetrain for a work machine, including driving an electric motor of the drivetrain being drivingly coupled to at least one wheel of the work machine, the work machine being subjected to a downhill force when traveling downhill, the downhill force bringing about an acceleration torque on the work machine. The method further includes counteracting the acceleration torque with a generator torque of the electric motor in generator mode, a maximum generator torque being dependent on an actual motor speed of the electric motor, and applying brakes in an automated manner when the work machine accelerates as a result of the downhill force. The brakes being applied reduces the actual motor speed until the maximum generator torque at a reduced actual motor speed is at least the same as the acceleration torque.
