SYSTEM AND METHODS FOR DETERMINING FUEL FILL LEVEL |
| 摘要 |
A method, comprising indicating an amount of a residual fuel in a fuel tank based on an initial rate of change of a fuel tank pressure during a refueling event. The initial rate of change of fuel tank pressure is proportionate to the amount of vapor dome space within the fuel tank, and thus proportionate to the amount of residual fuel left in the fuel tank. In this way, the fuel tank fill level may be accurately quantified, even during cases where the fill level indicator experiences degradation. |
