Abstract
A method for actuating a solenoid valve, which is loaded with a pneumatic pressure medium, in order to reduce a pressure (p) which is applied to the solenoid valve, where the solenoid valve assumes a closed switching position in the deenergized state and assumes a completely open switching position when it is energized with a switching current intensity (I) which is dependent on the applied pressure (p), where a first rise current final value (I) is predetermined, which first rise current final value is smaller than the switching current intensity (I), where the solenoid valve is energized with an actuating current which follows an actuating current profile (SV, SV), and where the actuating current profile (SV, SV) comprises a first rise phase (TA), in which the actuating current is increased to the predetermined first rise current final value (I), and, following said first rise phase, a first holding phase (TH) in which the actuating current is held constant at the first rise current final value (I).
