摘要：
An electronic control unit is provided with two types of gear change maps: a first gear change map based on the vehicle speed and the accelerator pedal operation amount; and a second gear change map based on the vehicle speed and the required drive force of the vehicle. The electronic control unit determines whether the automatic transmission should downshift with reference to the first gear change map, and determines whether the automatic transmission should upshift with reference to the second gear change map.
