A vehicle includes an engine, an EHC (electrical heated catalyst), a first MG (motor generator) generating a counter electromotive force at the time of vehicle collision, a battery, a PCU (power control unit) having a converter and an inverter performing power conversion between the battery and the first MG, and an ECU. The PCU is connected to the battery through an SMR (system main relay). The EHC is connected between the converter and the inverter through EHC relay. The ECU determines whether or not vehicle collision has occurred. When the vehicle collision has occurred, the ECU opens the SMR to electrically separate the battery and the PCU and closes the EHC relay to electrically connect the EHC and the first MG, so that the counter electromotive force generated in the first MG at the time of vehicle collision is consumed at the EHC. |
