A method for maintaining a predetermined voltage in a battery-supported vehicle electrical system during the operation of an electrical starter includes steps of operating the electrical starter on the vehicle electrical system during a first time phase in series with a limiting resistor, in order to limit the current flowing through the starter, and operating the electrical starter on the vehicle electrical system during a second time phase with a reduced limiting resistance, in order to increase a power converted by the starter. A transition from the first time phase to the second time phase is controlled on the basis of electrical parameters sampled during the first time phase at the limiting resistor.
