Beschreibung
Zusammenfassung:	A method for operating an electric drivetrain of a working machine is provided wherein the drivetrain comprises a work drive with an electric work motor and a travel drive with an electric travel motor and vehicle wheels, wherein the working machine experiences a speed deceleration from the outside that may result in a braking force acting on the vehicle wheels lower than a driving force acting on the vehicle wheels due to a moment of inertia of the travel motor. The method includes supplying the travel motor with a power in a direction opposite to an operating direction of the travel motor in order to reduce a rotational speed of the travel motor, if it is detected in advance using a situation detection that the braking force acting on the vehicle wheels as a result of the speed deceleration is lower than the driving force acting on the vehicle wheels.
