Method for controlling a filling process of an operating fluid container, and operating fluid container system

A method for controlling a filling process of an operating fluid container, which is fillable by a filling device via a filler pipe opening out into the operating fluid container, wherein the operating fluid container has a venting valve, which is electrically actuable between an open position, in which the operating fluid container is fluidically connected to atmosphere, at least indirectly, by the venting valve, and a closed position, in which the operating fluid container is fluidically separated from the atmosphere by the venting valve, comprising:

• a) moving the venting valve into its open position;
• b) determining a filling level of the operating fluid container;
• c) reducing a venting volume flow through the venting valve if the filling level of the operating fluid container has reached or exceeded a predetermined shut-off filling level;
• d) determining a filling stop of the filling device;
• and
• e) moving the venting valve into its closed position after a predetermined time period after determining the filling stop;
• and
• wherein a first venting volume flow through the venting valve after a determination that the filling level of the operating fluid container has reached or exceeded the predetermined shut-off filling level, and before the beginning of the predetermined time period, differs from a second venting volume flow through the venting valve during the predetermined time period.
