Abstract
A method for determining a fuel pressure present at a direct injection valve comprising a solenoid drive comprises (a) detecting a voltage induced in the solenoid drive within a time span comprising a closing point in time of the direct injection valve, and (b) determining the fuel pressure based on the detected induced voltage. Further, a corresponding device, a common rail system, a motor vehicle, and a computer program for determining the fuel pressure of a valve comprising a solenoid drive are provided.
