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.

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.
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, in the first operating mode, a current regulation of the coil current flowing through the coil arrangement is performed,
- in the second operating mode, differing from the first operating mode, the activation voltage is set without the current regulation;
- and, wherein the activation voltage is kept constant.
An activation device for a fluid solenoid valve in a fluid system, the activation device comprising:
- a driver circuit device for activating a coil arrangement of the fluid solenoid valve;
- a control device configured to apply an activation voltage to the 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.
