Abstract
A method for determining the opening point in time of a control valve having a coil drive of an indirectly driven fuel injector for an internal combustion engine of a motor vehicle may include: detecting the time curve of the current intensity of a current flowing through the coil drive, determining a current integral with respect to the detected current intensity as a function of the time and starting from a defined initial time, and determining a time at which the current integral reaches at least a predefined current integral reference value, wherein the determined time is the opening point in time of the control valve. A corresponding device and a computer program for determining the opening point in time of a control valve of an indirectly driven fuel injector are also disclosed.
