Claim 0:
1. A method for determining a switching state of a valve which is actuated by a coil, the method comprising:
respectively ascertaining a current flowing through the coil and a voltage applied to the coil at several times following one another with a specified time interval,
calculating an inductance variable of the coil on the basis of the currents, the voltage and the specified time interval, and
determining the switching state of the valve on the basis of the inductance variable of the coil,
wherein the inductance variable of the coil is compared with a first end value and a second end value,
wherein, when the inductance variable of the coil is at most a predetermined distance from the first end value, a first switching state is determined, and
wherein, when the inductance variable of the coil is at most a predetermined distance from the second end value, a second switching state is determined.
