摘要： An electrically heated catalyst (EHC) device has a catalyst that purifies exhaust gas from an engine, and is configured to heat the catalyst with electric power that is supplied from an electric storage device. A current sensor detects a current that is supplied to the EHC device. A current sensor detects an input/output current of the electric storage device. An electric control unit executes failure determination control to determine whether the current sensor has a failure. In the failure determination control, the ECU estimates a current that is supplied to the EHC device using a detection value of the current sensor and compares the estimated current with a detection value of the current sensor to determine whether the current sensor has a failure.

摘要： The number of opportunities where external charging of a vehicle parked in a residential parking space or a charging station in a predetermined period is available is counted as the number of opportunities (S200), and the number of times of the external charging performed in the opportunities in the same predetermined period is counted as the number of times of charging (S210). The number of times of charging is then divided by the number of opportunities to calculate and store a charging frequency (S220). Since the charging frequency is a ratio of the number of times that the external charging was performed to the number of opportunities where the external charging is available in the predetermined period, the ratio is used as an index that can offer more accurate determination regarding an external charging utilization status. As a result, various processing to promote external charging can be executed more properly.

摘要： An EHC (140) is configured to electrically heat a catalyst that purifies exhaust gas from an exhaust path of an internal combustion engine mounted on an electrically-powered vehicle, when a current passes through the EHC (140). A charger (120) converts AC electric power supplied from an external power supply (210) to a charging port into charging power of a power storage device (70) by a power conversion path including an insulating transformer (330). The EHC (140) is electrically connected to power lines (352p, 352g) which are provided on the primary side of the insulating transformer (330) on the power conversion path, and to which a DC voltage is output. In a case where the EHC (140) is operated when the vehicle travels, the charger (120) converts the electric power from the power storage device (70) into the DC voltage output to the power lines (352p, 352g) connected to the EHC (140), by a part of inverse conversion of power conversion at the time of external charging.
