Abstract (en)
[origin: WO2020078806A1] The invention relates to a method for determining a switched state of a valve. In said method, an inductance value is ascertained on the basis of current and voltage measurements, and the switched state is determined on the basis of the inductance value. The invention further relates to a solenoid valve assembly for carrying out said kind of method.
