Abstract
A method and a device are provided for determining the amount of fuel in the fuel tank of a motor vehicle. The fuel tank has a main storage reservoir which is provided with a filling level meter for determining the respective fuel therein and a reserve reservoir which is of substantially smaller volume in comparison with the main storage reservoir, which is closed in itself, and which is supplied with fuel by a pump from the main storage reservoir. After the main storage reservoir is emptied, the fuel reserve which is then still contained in the reserve reservoir is calculated as the difference of a defined volume of the reserve reservoir ( ) and the fuel consumption summed over time.
