Abstract
An electronic control unit executes navigation-cooperative SOC control in which traveling situations on a traveling route found through a search performed by a navigation system are predicted and a state-of-charge is controlled by adjusting an output of an engine based on the predicted traveling situations to control charging-discharging of an electricity storage device. The ECU does not execute the navigation-cooperative SOC control when a temperature of the electricity storage device falls below a prescribed temperature and thus charging-discharging of the electricity storage device is limited.
Claims5
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, and
- 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.
