Abstract: The invention relates to a method for controlling the parking process of a hybrid electric vehicle, in particular a mild hybrid electric vehicle, in which an electric motor and an internal combustion engine can act on the drive train at the same time and in which, furthermore, a starter motor is connected to the drive train. The principle of electric parking is to be solved by the invention. In order to achieve this, the electric motor is initially exclusively utilized as the drive for the parking process. When an obstacle is to be overcome in this case, which cannot be successfully overcome solely with the aid of the electric motor, the starter motor is activated.

Abstract: The tensioning pulley arrangement for a belt drive in an engine, is provided. In one example, the tensioning pulley arrangement includes a first tensioning pulley and a second tensioning pulley tensioning a belt with a spring force and a spring preload force generated by a first spring device coupled to the first and second tensioning pulleys.
