POWER OUTPUT DEVICE, CONTROL METHOD THEREFOR, AND VEHICLE

摘要

PROBLEM TO BE SOLVED: To cope with power required for an internal combustion engine even when increasing moderately after an engine speed of the internal combustion engine reaches an upper limit engine speed.

SOLUTION: A target engine speed Ne* and a target torque Te* of the engine are set (S125) using a reference operation line obtained when controlling an air-fuel ratio at a theoretical air fuel ratio, in the case where the engine requiring power Pe* is upper limit power Pemax or less. The target engine speed Ne* is set to an upper engine speed Nemax (S140) when a prescribed fuel amount increase prohibiting condition is not satisfied, in the case where the engine requiring power Pe* exceeds the upper limit power Pemax, and a target air fuel ratio used for the air-fuel ratio control of the engine 22 is set at a rich air-fuel ratio, based on the engine requiring power Pe* (S150).
