摘要

The method involves determining whether the vehicle is placed nearer or at a tank position by a positioning system and if so, a de-aeration or aeration is permitted or accomplished. A suitable information is evaluated before a de-aeration or aeration is permitted or accomplished. A negative pressure and positive pressure is provided at the tank position of a fuel tank. An independent claim is also included for a tank venting system of a motor vehicle for de-aerating and aerating a fuel tank.
