Abstract:
1. A hybrid vehicle, which is driven by motive power output from at least one of an internal combustion engine and a vehicle-driving electric motor, the hybrid vehicle comprising: an electricity storage device that stores electric power to be supplied to the electric motor; an electricity receiving portion that receives electric power supplied from an external power source outside of the vehicle; a charging device that performs voltage conversion of the electric power input through the electricity receiving portion to charge the electricity storage device; an electrically-heated catalyzer that is provided in an exhaust passage of the internal combustion engine and is capable of electrically heating a catalyst for purifying exhaust gas discharged from the internal combustion engine; and a controller that determines an occurrence of an abnormality in the electrically-heated catalyzer by supplying electricity from the electricity storage device to the electrically-heated catalyzer before charging of the electricity storage device by the power source is started and that, when it is determined that there is no abnormality in the electrically-heated catalyzer, performs electric power control so that charging of the electricity storage device by the power source is started and electricity is supplied from the power source to the electrically-heated catalyzer.
