Abstract
A method and device for controlling a shiftable planetary gear set in a belt drive of an internal combustion engine in a motor vehicle having a sun gear which is fixedly connected to a belt pulley, a ring gear which can be connected fixedly with respect to the housing by means of a brake which is activated by an electrically operated actuator which is effective along a distance which is monitored by a relative distance sensor, as well as a web which is connected to a crankshaft of the internal combustion engine and rotatably accommodates planetary gears, wherein situated between the sun gear and the web is a free wheeling mechanism which can be switched and rolled over in both directions and is switched by the same actuator along the travel distance.
