Abstract

A method for activating a fluid solenoid valve in a fluid system of a vehicle, in which, in order to set a switching mode, an activation voltage is applied to a coil arrangement of the fluid solenoid valve. The activation voltage is set depending on an operating criterion to at least two different operating modes, wherein, in a first operating mode, a current regulation of the coil current flowing through the coil arrangement is performed, and in a second operating mode, differing from the first operating mode, the activation voltage is set without the current regulation.
