1. A method of driving an electromagnetic load, comprising the steps of:
- predetermining a basic time duration during which the load is to be driven;
determining a correction delay time as a function of a power supplied to the load;
generating a corrected time duration by correcting the basic time duration of driving the load as a function of the correction delay time; and
driving the load for the corrected time duration.

Abstract
In a method and device for driving an electromagnetic load, especially a solenoid valve, which influences the fuel quantity to be injected into an internal combustion engine, the duration of the drive of the solenoid valve can be corrected by a delay time. The delay time can be predetermined as a function of the power supplied to the load.
