A method for monitoring a solenoid valve, the method including: applying a test signal on one side of the solenoid valve, the solenoid valve having a control coil for controlling an air pressure in a brake cylinder of an electro-pneumatic brake, wherein the solenoid valve has a supply voltage side, at which the control coil takes up an electric supply current, and a reference potential side, at which the control coil delivers the electric supply current; tapping a measurement signal on the other side of the solenoid valve; and determining the state of the solenoid valve based on a juxtaposition of the test signal and of the measurement signal. Also described are a related control apparatus, an electro-pneumatic brake, and a computer readable medium.
