Abstract

An electronic control unit (50) suppresses gear shifting more significantly in a second travel mode than in a first travel mode. Accordingly, frequent gear shifting of an automatic transmission (16; 204) in the second travel mode is suppressed, and superior ride quality is obtained. Meanwhile, an amount of a hysteresis in a gear shifting map is smaller in the second travel mode (gear shifting lines 2, 3) than in the first travel mode (a gear shifting line 4). Thus, duration of travel at an optimum gear stage is extended in the second travel mode, and fuel economy is improved. That is, in the second travel mode, drive power responsiveness to an acceleration and deceleration operation as in the first travel mode is unnecessary. Thus, even when gear shifting is suppressed, there is a low possibility that a driver feels a sense of discomfort.
