Abstract
A method for controlling a filling operation of a vehicular liquid storage system including a tank equipped with a filler pipe and a shut-off valve, the method including detecting the start of a refilling event; while the shut-off valve is open, observing whether a measured fill level of the tank has reached a predetermined fill level; if the predetermined fill level has been reached, performing the following steps: closing the shut-off valve to induce a shut-off of a filling nozzle; when a first pressure criterion is met, opening the shut-off valve; and when a second pressure criterion is met, closing the shut-off valve. The second pressure criterion includes a decrease of pressure inside the tank below a predetermined pressure level.
