Abstract

The invention relates to a method for learning and determining a minimum injector specific electric actuation duration for at least one injection valve of an internal combustion engine of a motor vehicle. Starting with a specified electric actuation duration which definitely does not lead to an injection the electric actuation durations are increased stepwise in each motor stopping process and/or in each motor starting process in successive stopping processes and/or in successive starting processes of the internal combustion engine up to an actuation duration with which an injection with a combustion occurs and then said actuation duration can be determined as the minimum electric actuation duration. The invention further relates to a corresponding device.
