摘要： A circuit arrangement for detecting a solenoid valve type in vehicles, including at least one solenoid valve in the circuit arrangement for detecting the solenoid valve type and having at least one coil winding having a resistance of the typical order of magnitude for a predetermined vehicle electrical distribution system supply voltage, a constant current source, arranged to impress a predetermined measurement current into the one coil winding of the solenoid valve, a current mirror circuit, arranged to generate a second voltage on a detection section of the circuit arrangement from a first voltage produced as a result of the impressed measurement current on the at least one coil winding of the at least one solenoid valve, in which the second voltage produced on the detection section is passed out, on the detection section, directly to a microcontroller in a control device for determining the type of solenoid valve.
