Method and device for determining the fuel volume in a fuel container

A device for determining a value of a fuel volume in a fuel container for a current point in time, wherein the device is configured to:

• determine an estimated value of the fuel volume for the current point in time on a basis of a preceding value of the fuel volume for a preceding point in time and on a basis of removal data with respect to a fuel removal from the fuel container;
• determine a minimum value and/or a maximum value of the fuel volume for the current point in time on a basis of a measured value of a fill level sensor of the fuel container for the current point in time;
• and
• determine the value of the fuel volume for the current point in time on a basis of the estimated value of the fuel volume and on a basis of the minimum value and/or the maximum value of the fuel volume for the current point in time,
• wherein, in order to determine the value of the fuel volume for the current point in time, the device is configured to:
• determine whether the estimated value of the fuel volume for the current point in time falls in a value interval for the fuel volume defined by the minimum value and the maximum value;
• and
• accept the estimated value of the fuel volume for the current point in time as the value of the fuel volume for the current point in time in response to determining that the estimated value of the fuel volume for the current point in time falls in the value interval for the fuel volume.
