Abstract
A hybrid vehicle includes a canister that adsorbs evaporative fuel generated in the fuel tank for an internal combustion engine. The hybrid vehicle can drive a drive wheel even when the internal combustion engine is stopped. When the internal combustion engine of the hybrid vehicle is stopped and a prescribed set of conditions is satisfied, the internal combustion engine is rotated by the generator. When the internal combustion engine of the hybrid vehicle is rotated by the generator, the evaporative fuel adsorbed in the canister is supplied to the upstream side of an upstream side exhaust catalytic converter device. In the hybrid vehicle, the introduced evaporative fuel as reducing agent is adsorbed in the upstream side exhaust catalytic converter device and a downstream side exhaust catalytic converter device.
