Abstract

A cruising distance coefficient is set that is smaller than a value of 1 and that becomes smaller as a use index indicating a degree of use of external charging gets smaller, and a cruising distance is calculated by multiplying a fuel quantity by the set cruising distance coefficient and a fuel consumption coefficient. Then, a display cruising distance is calculated by subtracting from the cruising distance a value obtained by subtracting a set-time travel distance Lset, obtained when the cruising distance is calculated, from a travel distance from a travel distance meter, and the calculated display cruising distance is displayed on a display device in front of a driver's seat.

First claim

What is claimed is

1 . A hybrid vehicle comprising:
an engine; a fuel tank configured to supply fuel to the engine; a motor; a battery configured to supply electric power to the motor; a charger configured to carry out external charging that charges the battery using an external power source; and an electronic control unit configured to adjust a cruising distance, the cruising distance being a distance that the hybrid vehicle can travel using the fuel, such that the cruising distance when a use index indicating a degree of use of the external charging in a predetermined time period is small is smaller than the cruising distance when the use index is large.

2 . The hybrid vehicle according to claim 1 , further comprising
a display device, wherein the electronic control unit is configured to control the display device such that the display device displays a distance that is smaller than a travelable distance calculated from a fuel quantity in the fuel tank, as the cruising distance.

3 . The hybrid vehicle according to claim 2 , wherein
the electronic control unit is configured to calculate the cruising distance by multiplying the travelable distance calculated from the fuel quantity in the fuel tank, by a coefficient that becomes smaller as the use index gets smaller.

4 . The hybrid vehicle according to claim 1 , wherein
the electronic control unit is configured to limit fuel supply from the fuel tank to the engine when the cruising distance has been traveled.

5 . The hybrid vehicle according to claim 1 , wherein
the electronic control unit is configured to limit refueling to the fuel tank.

6 . The hybrid vehicle according to claim 5 , wherein the electronic control unit is configured to close a refueling port of the fuel tank.

7 . The hybrid vehicle according to claim 5 , wherein
the electronic control unit is configured to cause a refueling device to determine that the fuel tank is full of fuel when a fuel quantity in the fuel tank is less than 100%.

8 . The hybrid vehicle according to claim 5 , wherein
the fuel tank is configured such that a capacity of the fuel tank is variable, and the electronic control unit is configured to reduce the capacity of the fuel tank.

9 . The hybrid vehicle according to claim 5 wherein
the electronic control unit is configured to transmit, to a refueling device configured to carry out refueling in response to receipt of a required refueling quantity from the hybrid vehicle, a refueling quantity that is smaller than a refuelable quantity calculated from a fuel quantity in the fuel tank, as the required refueling quantity.

10 . The hybrid vehicle according to claim 5 , wherein
the electronic control unit is configured to slow down a refueling speed by causing an opening area of a portion of a refueling pipe to he smaller than a normal area,

11 . The hybrid vehicle according to claim 5 , wherein
the electronic control unit is configured to transmit a signal to a refueling device configured to be communicable and to be able to adjust a refueling speed such that the refueling device carries out refueling at a refueling speed slower than a normal refueling speed.
