Abstract: A hybrid vehicle according to one of embodiments of the present invention generates a driving torque using an internal combustion engine, an motor generator, and the like when a shift position is a driving position, the driving torque being determined based on a selected driving mode (e.g., a power mode to give priority to the power, and a normal mode to give priority to fuel consumption) and an accelerator operation amount. On the other hand, when the shift position is a neutral position, the vehicle maintains a rotational speed of the engine at a constant speed (including zero when the engine is stopped) regardless of the accelerator operation amount. When the accelerator operation amount becomes equal to or larger than an accelerator operation amount threshold while the neutral position is selected, the vehicle supplies information indicating that the neutral position is selected to a driver. The accelerator operation amount threshold is determined based on the driving mode.

Abstract: When an ECU disconnects a second power storage device BAT2 from a drive device 90 while a hybrid vehicle is traveling, ECU disconnects one of a contact point B1 and a contact point G2 of a system main relay SMR2 and causes the vehicle to continue traveling using electric power supplied from a first power storage device BAT1 to drive device.

If the charge is not discharged appropriately, ECU determines that welding occurs in at least one of system main relay SMR1 and system main relay SMR2.

Abstract: In an external charging mode of a plug-in hybrid vehicle, electric power from an external power supply electrically connected to a connector is converted and supplied to a power line electrically connected to a battery and an electric air-conditioning device. If charge allowable power of the battery is smaller than or equal to a prescribed value when the electric air-conditioning device is operated, a DFR is opened to stop electric power supply from the external power supply and drive the electric air-conditioning device by electric power of the battery. As a result, even if the consumed power of the electric air-conditioning device is suddenly decreased, the inflow of surplus electric power that cannot be absorbed by the battery from the external power supply can be prevented.

Abstract: In a vehicle including a charge circuit for carrying out external charging to charge a vehicle-mounted battery with a power supply external to the vehicle, a vehicle ECU. determines that there is an impedance error when a state where a reduction width of an input voltage Vin applied to the charge circuit from the power supply external to the vehicle is exceeding a threshold width ?V continues for a predetermined time, and outputs a first termination instruction to a charger ECU. The charger ECU receiving the first termination instruction causes the charge circuit to stop to terminate external charging. The charger ECU controls the charge circuit such that, when the input voltage Vin falls down to a threshold voltage V1 the current flowing through an external power supply system is reduced to suppress further reduction in the input voltage Vin.
