| 发明名称 | System and method for indicating fuel efficiency of flexible fuel vehicle | ||
| 摘要 | A method and a system for indicating a fuel efficiency in a vehicle is provided that includes a density sensor configured to measure the density of a fuel mixture stored in a fuel tank. In addition, a controller is configured to derive the mix ratio related to the fuel mixture via the density measured by the density sensor and change a reference value of a fuel calculation logic based on the mix ratio. In addition, the controller is configured to determine the fuel efficiency based on the changed reference value. | ||

| 主权项 | 1. A system for indicating a fuel efficiency of a vehicle, comprising: a density sensor configured to measure a density of a fuel mixture stored in a fuel tank as being attached to a fuel tank; and a fuel efficiency determining unit configured to: derive a mix ratio by inserting the density measured by the density sensor into a fuel data map composed of densities and mix ratios;change a reference value of a fuel calculation logic based on the mix ratio; anddetermine the fuel efficiency based on the changed reference value, wherein the fuel efficiency determining unit is operated by a controller. | ||
