Abstract

A hybrid vehicle enabling reliable travel to the destination in second travel mode in which the vehicle travels with the engine off and enabling more effective use the second travel mode. In this vehicle, a electric power travel mode travelable distance calculation section calculates the travelable distance based on the average traveling consumed current value inputted from average traveling consumed current value calculation section and the battery capacity SOC inputted from a battery capacity calculation section, and outputs the result to a display section. A fuel travelable distance calculation section calculates the remaining travelable distance based on the remaining fuel inputted from a remaining fuel amount measuring section and the fuel consumption inputted from a fuel consumption calculation section, and outputs the result to the display section. The display section displays the remaining travelable distance for the total of the remaining fuel and the battery capacity SOC for traveling, based on the travelable distance inputted from the electric power travel mode travelable distance calculation section and the remaining travelable distance inputted from the fuel travelable distance calculation section.

Claims

1. A hybrid vehicle having a first travel mode in which the vehicle travels with an engine on and a second travel mode in which the vehicle travels with the engine off, the hybrid vehicle comprising:

a setting section that selectively sets the first travel mode and the second travel mode;

a detecting section that detects that the second travel mode is set;

a determining section that determines whether or not the vehicle is able to travel to a destination with a power amount accumulated in a battery when the detecting section detects that the second travel mode is set; and

a control section that makes a shift to the second travel mode when the determining section determines that the vehicle is able to travel to the destination.

2. The hybrid vehicle according to claim 1, wherein the determining section determines whether or not the vehicle is able to travel to the destination based on consumed power during traveling and the power amount accumulated in the battery.

3. The hybrid vehicle according to claim 1, further comprising a charging section that charges the battery by setting a target charge value of the battery greater than a normal setting value when the determining section determines that the vehicle is not able to travel to the destination.

4. The hybrid vehicle according to claim 1, further comprising:

an input section that inputs the destination; and

a current position detecting section that detects a current position,

wherein the determining section calculates a travel distance from the current position to the destination and determines whether or not the vehicle is able to travel to the destination based on the travel distance and the power amount accumulated in the battery.
