Fuel fill volume estimation using virtual zone and fuel tank float

A method comprising:

• dividing, with a processor of a vehicle, a fuel tank into virtual zones, the virtual zone including a first zone, the first zone being an area of the fuel tank that is not measurable by a fuel sender card coupled to a fuel tank float;
• when the vehicle is not in motion and a position of the fuel tank float changes by a threshold amount, measuring an initial fuel level;
• when the position of the fuel tank float does not change for a threshold period of time, measuring a final fuel level;
• responsive to the final fuel level being in one of the virtual zone that is not the first zone and the initial fuel level being in the first zone, calculating an amount of fuel added to the fuel tank based on measurements of fuel injected to an engine by fuel injectors and measurements of the fuel sender card;
• and
• displaying the amount on a dashboard display.

A vehicle comprising:

• a fuel sender card coupled to a float;
• and
• processors to:
• responsive to an initial fuel level being in an area of a fuel tank that is not measurable by the fuel sender card, calculate an added fuel amount based on measurements of fuel injected to an engine by fuel injectors and measurements of the fuel sender card;
• and
• display the added fuel amount on a dashboard display.
