METHOD AND DEVICE FOR DETERMINING THE STATE OF AN ELECTRICALLY CONTROLLED VALVE

摘要

The invention relates to a method (3) for determining (33) a state characteristic value (28) of a electric device (4) controlled by a temporally variable control signal (17). The at least one state characteristic value (28) is determined using the frequency of the temporally variable control signal (17) and/or the switching characteristics of the temporally variable control signal (17).
