摘要
In an assembly with a planetary gear train, which includes the elements sun gear, planet carrier with planetary gears and ring gear, two elements, in particular the sun gear and the planet carrier, are coupled with each other via an overrunning clutch. A clutch bridges the overrunning clutch. Bridging is discontinuous and controlled by a control device based on the relative rotation of the two elements to be coupled. For example, one rotation speed sensor can measure the rotation speed of an electric machine, whereas another rotation speed sensor can measure the rotation speed of a crankshaft of an combustion engine. In a motor vehicle, the combustion engine can be coupled with an electric machine, using different gear ratios during startup or boosting and in generator operation. In addition, the electric machine can drive an air-conditioning compressor when the combustion engine is not running.
