A device for controlling a starting process of a vehicle electrical wiring system of a vehicle. The vehicle wiring system has a first energy store and a second energy store that are connectable in series as a result of a series switching element closing. The vehicle wiring system has a first DC-DC voltage converter with: a first pole that is coupled to a coupling point between a first pole of the first energy store and the series switching element, and a second pole that is coupled to a second pole of the first energy store via a second converter switching element. The device ascertains, before the series switching element closes, voltage information relating to a voltage across the series switching element. The device takes the voltage information as a basis for operating the first DC-DC voltage converter to cause the voltage across the series switching element to be reduced before the series switching element closes.
