Device for displaying available travel distance of vehicle

A display device for displaying an available travel distance of a vehicle by calculating an available amount of fuel in a fuel tank on the basis of outputs of a first sensor and a second sensor which are provided in the fuel tank,

• the second sensor detecting the available amount of fuel in the fuel tank at a fuel level higher than a reserve point in the fuel tank,
• the display device comprising:
• an electronic control unit (ECU) that comprises:
• an available amount-of-fuel calculator configured to calculate the available amount of fuel from the output of the first sensor at a fuel level lower than the reserve point and from the output of the second sensor at a fuel level higher than the reserve point,
• an average mileage calculator configured to calculate an average mileage from a consumed amount of fuel and a vehicle's traveled distance per unit time, and
• an available travel distance calculator configured to calculate the available travel distance from the available amount of fuel and the average mileage;
• and
• a display configured to display the available travel distance,
• wherein the available amount-of-fuel calculator uses a learned value based on the outputs of the first and second sensors as a corrective value for correcting the output of the second sensor when the calculation of the available amount of fuel switches from being based on the output of the second sensor to being based on the output of the first sensor.
