Electric motor for supporting function

The invention relates to a device (1), comprising an electric motor (10) for supporting at least one function (12) in a motor vehicle - preferably a car - , a DC/DC converter (16) and a vehicle system controller (18), wherein the electric motor (10) is connected to an output voltage (22) of the DC/DC converter (16) which in turn is connected to a system voltage (14) of the motor vehicle so that the DC/DC converter (16) is switched between the system voltage (14) and the electric motor (10), wherein the DC/DC converter (16) is connected in addition to the vehicle system controller (18). The invention also relates to a method in which such a device is being used. 本发明涉及种装置（1），所述装置包括用于在机动车优选载客汽车中支持至少个功能部（12）的电动马达（10）、直流转换器（16）和车辆系统控制机构（18），其中所述电动马达（10）被连接到所述直流转换器（16）的输出电压（22）处，所述直流转换器又被连接到所述机动车的系统电压（14）处，从而使得所述直流转换器（16）被连接在所述系统电压（14）与所述电动马达（10）之间，其中所述直流转换器（16）额外地被连接到所述车辆系统控制机构（18）处。并且本发明还涉及种方法，在所述方法中使用这种装置。
