Abstract
The priority sequence in a control of adjusting the drive power with respect to a vehicle drive power request is set in the sequence of: (1) an engine output increase, (2) a motor output increase, and (3) a gear speed change in a gear ratio increasing direction. More specifically, a gear speed of a least gear ratio is selected within such a range that an engine revolution speed higher than or equal to a predetermined lower limit revolution speed is attainable. A requested drive power is achieved singly by an engine output with the gear speed selected. When the requested drive power is not achievable singly by the engine output, the requested drive power is achieved by the engine output and a motor output. When the requested drive power is not achievable by the engine output and the motor output, the gear speed is changed in a gear ratio increasing direction.
