The invention relates to a device for controlling a starting process of an on-board electrical system of a vehicle, comprising a first energy store and a second energy store, which can be connected in series by closing a series switching element, comprising a first DC voltage converter having a first pole and a second pole, the first pole is coupled to a coupling point between the first pole of the first energy store and the series switching element, and the second pole is coupled to the second pole of the first energy store via the second converter switching element. The device is designed to determine voltage information about a voltage across the series switching element prior to closing the series switching element. The device is also designed to reduce the voltage across the series switching element before closing the series switching element by operating the first DC-DC converter on the basis of the voltage information.

    本发明涉及一种用于控制车辆的车载电气系统的启动过程的装置,所述车载电气系统包括第一蓄能器和第二蓄能器,它们可以通过闭合串联开关元件而串联,所述车载电气系统包括具有第一极和第二极的第一直流电压转换器,所述第一极与在第一蓄能器的第一极和串联开关元件之间的耦合点耦合,所述第二极经由第二转换器开关元件与第一蓄能器的第二极耦合。所述装置构成用于在闭合串联开关元件之前确定关于串联开关元件上的电压的电压信息。所述装置还构成用于根据所述电压信息通过运行第一直流电压转换器实现在闭合串联开关元件之前使串联开关元件上的电压降低。
