Hybrid vehicle and method for controlling same

A method for controlling a hybrid vehicle including an internal combustion engine that generates a driving force for the hybrid vehicle;

• a generator that generates electric power by using an output of the internal combustion engine;
• an electric storage device that stores the electric power generated by the generator;
• an electric motor that generates a driving force for the hybrid vehicle by receiving at least one of the electric power that is generated by the generator and the electric power that is stored in the electric storage device;
• a heating apparatus that heats a vehicle cabin, the heating apparatus including an electric heater that heats the vehicle cabin by using the electric power that is stored in the electric storage device;
• and an electronic control unit, the method comprising:
• (a) controlling traveling of the vehicle by the electronic control unit by selectively applying a charge depleting mode and a charge sustaining mode, the charge depleting mode being a mode in which a state of charge of the electric storage device is consumed and the charge sustaining mode being a mode in which the state of charge is maintained;
• (b) controlling traveling of the vehicle by the electronic control unit by selecting a EV travel or a HV travel based on a traveling power of the hybrid vehicle in both the charge depleting mode and the charge sustaining mode, the EV travel being a travel by using the electric motor with the internal combustion engine stopped, the HV travel being a travel by using the driving force of the internal combustion engine in addition to the driving force of the electric motor or instead of the driving force of the electric motor;
• and
• (c) controlling the electric heater by the electronic control unit so that the heating by the electric heater is more limited in the charge sustaining mode than in the charge depleting mode.
