Abstract
The disclosure relates to 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 applied to a coil arrangement of the fluid solenoid valve. It is provided here that 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.
Claims23
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, and, in the second operating mode, differing from the first operating mode, the activation voltage is set without the current regulation.
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, 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.
