A control device for a two-stage solenoid valve, including an activation unit which outputs a current flowing through a solenoid coil of the solenoid valve as a switching signal. The solenoid valve is switchable from its de-energized switching state into its energized switching state by increasing a current intensity of the switching signal from zero to a switching current intensity. The solenoid valve is switchable from its energized switching state into its de-energized switching state by designing the activation unit to set the current intensity of the switching signal during a switching time interval to at least one current intensity value between zero and the switching current intensity, reduce it to zero after the switching time interval and during the switching time interval, increase it at least twice, each for a predefined pulse time interval, to a predefined current pulse value between zero and the switching current intensity.
