摘要

When an engine demand power Pe* is lower than an upper limit power Pemax, target rotation speed Ne* and target torque Te* of an engine are set using a reference operation line obtained when air fuel ratio control is performed at a theoretical air fuel ratio (S125). When the engine demand power Pe* exceeds the upper limit power Pemax, the target rotation speed Ne* is set at an upper limit rotation speed Nemax if predetermined fuel increment prohibition conditions are not satisfied (step S140), and a target air fuel ratio for use in air fuel ratio control of the engine (22) is set at rich air fuel ratio based on the engine demand power Pe* (S150).
