An automatic transmission control device is provided with: an automatic transmission mode for automatically shifting on the basis of a relationship between an automatic transmission shift line defined by vehicle speed, and an operating point defined by the detected vehicle speed; and a manual transmission mode for shifting on the basis of a manual operation by the driver and a relationship between a manual transmission shift line defined by vehicle speed and the detected vehicle speed itself, and controlling so as to reject an upshift operation by the driver when the detected vehicle speed is at or below a prescribed vehicle speed. The automatic transmission control device is further provided with: a shifting properties change means for changing the shifting properties of the automatic transmission in a manner such that downshifting occurs at a faster vehicle speed when the throttle opening is less than a prescribed opening in comparison to when the throttle opening is equal to or more than the prescribed opening; and a shifting properties change prohibiting/allowing means for prohibiting a change to the shifting properties until downshifting has occurred once while the manual transmission mode is selected, and allowing a change to the shifting properties after downshifting has occurred once. As a result, it is possible to improve fuel efficiency and suppress imparting an unnatural sensation to the driver. |
