Abstract
A method is provided for determining a time duration for an electric actuation of a valve which has a coil drive, in particular of a direct-injection valve for an internal combustion engine. The method may include a deactivation of a current flow through a coil of the coil drive, such that the coil is in a currentless state, a detection of a time profile of a voltage induced in the currentless coil, a determination of the closing time of the valve on the basis of the detected time profile, and a determination of a time duration of the electric actuation of the valve for a future injection process on the basis of the determined closing time. A corresponding device and a computer program for carrying out the described method are also disclosed.
