Hybrid vehicle

A hybrid vehicle comprising:

• an engine;
• an electricity storage device configured to store electric power generated using an output of the engine;
• an electric motor configured to generate drive power for traveling, using the electric power received from the electricity storage device;
• a controller configured to control a state-of-charge of the electricity storage device by adjusting the output of the engine to control charging-discharging of the electricity storage device;
• and
• a navigation system configured to search for a traveling route of the hybrid vehicle, wherein
• the controller is configured to predict a traveling situation on the traveling route found through a search performed by the navigation system,
• the controller is configured to execute navigation-cooperative control for controlling the state-of-charge by controlling charging-discharging of the electricity storage device based on the predicted traveling situation,
• the controller is configured not to execute the navigation-cooperative control when a temperature of the electricity storage device falls below a prescribed temperature at which charging-discharging of the electricity storage device is limited,
• the controller is configured to control the state-of-charge of the electricity storage device so that the state-of-charge of the electricity storage device is adjusted to a target state-of-charge,
• the controller is configured to set the target state-of-charge based on the predicted traveling situation on the traveling route, and
• the controller is configured to execute temperature increasing control when the temperature of the electricity storage device falls below the prescribed temperature, the temperature increasing control including increasing the target state-of-charge to exceed a reference value and decreasing the target state-of-charge to fall below the reference value.
