Claim:
1. A vehicle having an electric power supply mode, the vehicle comprising: an electric power storage device; an internal combustion engine configured to generate power by combustion of a fuel; a fuel tank configured to store the fuel; a fuel gauge configured to detect an amount of the fuel remaining in the fuel tank; an electric power generation mechanism configured to generate electric power with the power from the internal combustion engine; an electric power converter configured to convert electric power from at least one of the electric power storage device and the electric power generation mechanism to supply electric power in the electric power supply mode; an electric power node configured to output the supply electric power from the electric power converter; and an electronic control unit configured to put the internal combustion engine into operation and control the operation of the internal combustion engine for electric power supply to continue once an SOC of the electric power storage device is reduced to a first reference value during the electric power supply in which the internal combustion engine is stopped in the electric power supply mode, wherein the electronic control unit is configured to: i) calculate an electric power supply possible time based on a remaining amount value recognized as a discrete numerical value based on an output of the fuel gauge and the SOC in a first period between an initiation of the electric power supply and generation of a recovery history in the SOC resulting from charging of the electric power storage device with the electric power from the electric power generation mechanism attributable to the operation of the internal combustion engine in the electric power supply mode, and ii) calculate the electric power supply possible time based on the remaining amount value without taking the SOC into account after the generation of the recovery history.
