Abstract
A method and a device for driving an electromagnetic consumer (device) which includes a movable element, in particular a solenoid valve for metering fuel into an internal combustion engine. Within a timing window, a switching instant is determined by evaluating the time characteristic of a variable which corresponds to the current flowing through the electromagnetic consumer. A clocked voltage control is provided within the timing window.
