Zusammenfassung:	The present invention relates to a method (100) for controlling one or two electrically driven axles (1a, 1b) of a vehicle with electric motors (EM1, EM2), each connected to an output (2, 2a, 2b) via a respective power transmission path (3, 4), comprising the following steps: determining (101a) values for a speed and a torque applied to at least one mechanical component (5) of the power transmission paths (3, 4) and/or the electric motors (EM1, EM2); determining a value of a damage condition of the at least one mechanical component (5) resulting from damage inputs over a predefined period of time; and controlling (107) the electrically driven axles (1a, 1b) taking into account the damage condition of the at least one mechanical component (5).
