Abstract:
The invention relates to a method for controlling an opening and/or closing process of an electromagnetic valve by controlling a flow of a current and/or of a voltage with which a coil of the electromagnetic valve is flowed through or supplied in order to move a control valve element, during which a number of points in time of the opening and/or closing process are detected that result, in particular, from physical characteristic values of the current flow and/or of the electromagnetic valve. The duration between the detected points in time of a preceding opening and/or closing process is used as a controlled variable for controlling the flow of current and/or of voltage during a subsequent opening and/or closing process.
