ABSTRACT:
In hybrid vehicle, when the shift position SP is set to the S position at which a driver is allowed to select any one of the shift positions SP1to SP6, and it is determined that warm-up of a purifying device has not been completed, the target air-fuel ratio AF* is set based on the S position/low coolant temperature-time target air-fuel ratio setting map. The air-fuel ratio AF* set based on the S position/low coolant temperature-time target air-fuel ratio setting map tends to be richer than the target air-fuel ratio AF* set based on any one of the normal-time target air-fuel ratio setting map and the D position/low coolant temperature-time target air-fuel ratio setting map that are used when the D position is selected.
