A method for is provided actuating at least one electromagnetic valve containing at least one coil, which can be excited by an excitation current, and an armature, in which the excitation current can be set such that, in response to a signal for actuating the armature from one position into another position, it causes the actuator to move as a result of an excitation current threshold being exceeded, and is kept at a value which is lower by comparison in order to hold the armature in a specific position. The excitation current, which is greater than zero but below the excitation current threshold, is applied at least temporarily to the electromagnetic valve even if no signal for actuating or for holding the armature is present.

What is claimed is: 1. A method for actuating at least one electromagnetic valve containing at least one coil, which is excitable by way of an excitation current, and an armature, wherein the excitation current is settable such that, in response to a signal for actuating the armature from one position into another position, the excitation current causes the armature to move as a result of an excitation current threshold being exceeded, and is kept at a value which is lower by comparison in order to hold the armature in a specific position, the method comprising the acts of: for reducing an ohmic resistance of the coil, applying an excitation current which is greater than zero but below the excitation current threshold, at least temporarily, to the electromagnetic valve even if no signal for actuating or for holding the armature is present; and wherein the excitation current is applied to the coil at a certain time interval after a holding phase of the armature is ended. 2. The method as claimed in claim 1, wherein an excitation current below the excitation current threshold is applied to the coil as a function of ambient temperature. 3. The method as claimed in claim 1, wherein an excitation current below the excitation current threshold is applied before a first functionally induced actuation of the electromagnetic valve, when the temperature of the electromagnetic valve is equal to an ambient temperature. 4. The method as claimed in claim 2, wherein an excitation current below the excitation current threshold is applied before a first functionally induced actuation of the electromagnetic valve, when the temperature of the electromagnetic valve is equal to an ambient temperature. 5. The method as claimed in claim 1, wherein an excitation current below the excitation current threshold is applied to the coil for a certain period of time. 6. The method as claimed in claim 2, wherein an excitation current below the excitation current threshold is applied to the coil for a certain period of time. 7. The method as claimed in claim 3, wherein an excitation current below the excitation current threshold is applied to the coil for a certain period of time. 8. The method as claimed in claim 4, wherein an excitation current below the excitation current threshold is applied to the coil for a certain period of time. 9. The method as claimed in claim 5, wherein the period of time is dependent on the ambient temperature. 10. The method as claimed in claim 5, wherein the period of time is dependent on the ambient temperature. 11. The method as claimed in claim 7, wherein the period of time is dependent on the ambient temperature. 12. The method as claimed in claim 8, wherein the period of time is dependent on the ambient temperature.
