  • Publication number: 20160257296
    Abstract: A controller for a hybrid vehicle is a controller used for a hybrid vehicle that is equipped with an internal combustion engine, a rotating electric machine, and an electric storage device, and that is capable of an external power supply. The controller includes a required-power information obtaining section that obtains required power, and a control section that controls the hybrid vehicle so as to cause the internal combustion engine to drive the rotating electric machine in order to supply power generated by the rotating electric machine to the outside of the hybrid vehicle without charging the electric storage device, when the required power is greater than predetermined power.

  • Publication number: 20150344023
    Abstract: A control unit for a hybrid vehicle determines whether warming of an engine is insufficient in an outside electric power feed mode. When the warming of the engine is insufficient, it is determined whether current time is in an initial period of electric power feed. When the current time is in the initial period of the electric power feed, only electric power of an electric storage device is supplied to the outside in a state that the engine is off. When the current time is not in the initial period of the electric power feed, the engine is turned on, and only electric power generated in a motor is supplied to the outside. When the warming of the engine is sufficient, the electric power generated in the motor, the electric power of the electric storage device, or both of them are supplied to the outside.

  • Publication number: 20150175008
    Abstract: Vehicle is configured to supply power to outside of a vehicle. Vehicle includes an engine, a battery, a first MG configured to generate power with use of motive power of the engine, a switching unit configured to switch power supplied to outside of the vehicle between power generated by the first MG and power stored in the battery, an ECU configured to control the switching unit, and a detection unit configured to allow the ECU to determine whether or not the vehicle is located indoors. When the ECU determines that the vehicle is located indoors based on an output from the detection unit, it controls the switching unit so that the power supplied to outside of the vehicle to be switched from power generated by the first MG to power stored in the battery.
