1. A method for activating a fluid solenoid valve in a fluid system of a vehicle, the method comprising:
applying an activation voltage to a coil arrangement of the fluid solenoid valve in order to set a switching mode, wherein the activation voltage is set in dependence upon an operating criterion to at least two different operating modes including a first operating mode and a second operating mode, wherein said activation voltage includes a voltage applied during a pulling-in of the fluid solenoid valve;
wherein, in the first operating mode, a current regulation of the coil current flowing through the coil arrangement is performed, and,
in the second operating mode, differing from the first operating mode, the activation voltage is set without the current regulation.
