Abstract
An ECU determines whether or not a road surface changes from a low μ road surface to a high μ road surface based on image data obtained by a camera sense. When the ECU determines that the accelerator pedal operation amount deceases greatly in a predetermined determination period from a time point at which a drive wheel slip state occurs in a case where the ECU determines that the road surface changes from the low μ road surface to the high μ road surface, it prohibits upshift operation of an automatic transmission over a predetermined period from that time point.
