Abstract: 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.
