1. A hybrid vehicle comprising:

  • an engine configured to output driving power;

    a motor configured to output the driving power;

    a battery configured to exchange electric power with the motor;

    a navigation system configured to set a travel route to a destination and carry out route guidance, the travel route including a plurality of travel sections; and

    a controller configured to set a travel plan for preferentially allocating an electric traveling priority mode to each of the travel sections, the electric traveling priority mode configured to carry out electric traveling in which the vehicle travels while the engine is stopped in preference to hybrid traveling in which the vehicle travels while the engine is operated, the controller configured to carry out a navigation coordination traveling in which the vehicle travels in accordance with the travel plan, the controller being configured to stop the navigation coordination traveling when a state of charge of the battery becomes lower than or equal to a first switching threshold while the vehicle is traveling in the electric traveling priority mode in accordance with the travel plan as the navigation coordination traveling, the controller being configured to resume the navigation coordination traveling when the state of charge of the battery becomes higher than or equal to a second switching threshold higher than the first switching threshold after a stop of the navigation coordination traveling, the controller being configured to set a first predetermined state of charge for the first switching threshold when there is no regenerative travel section, in which it is predicted that the motor is driven to regenerate electric power, among the travel sections ahead of the currently traveling travel section on the travel route, and the controller being configured to set a second predetermined state of charge lower than the first predetermined state of charge for the first switching threshold when there is the regenerative travel section among the travel sections ahead.
