Zusammenfassung:Methods and systems are provided for tensioning a belt of a belt drive of an internal combustion engine. In one example, a movable tensioning means assigned to an active tensioner is provided, which applies a force to a belt of a belt drive, and the active tensioner is controlled such that a compression of a spring of the tensioner is at least countered, so that a movement of the tensioning means under the load of the belt is at least hindered. The belt is then excited to vibration in a contact zone between the belt and the movable tensioning means by use of a starter so that the tensioning means exposed to the force of the spring is moved further in the direction of the belt under expansion of the spring, whereby the belt is tensioned.
