A vehicle comprising: a drive power source (12; 202); an automatic transmission (16; 204) configured to establish plural gear stages, each of the plural gear stages having a different gear ratio; and an electronic control unit configured to execute a first travel mode and a second travel mode, the first travel mode being a mode in which drive power control and gear shifting control of the automatic transmission (16; 204) are executed in accordance with an acceleration and deceleration operation by a driver, and the second travel mode being a mode in which a target travel state of the vehicle is set without depending on an acceleration and deceleration operation by a driver present in the vehicle in a state in which the drive power control and the gear shifting control are executed, as a gear shifting condition of the gear shifting control in the first and second travel modes, an upshift condition and a downshift condition being defined based on a parameter related to drive power and a parameter related to a vehicle speed, an amount of a hysteresis between a specified upshift condition and a specified downshift condition in the first travel mode differing from the amount of the hysteresis between the specified upshift condition and the specified downshift condition in the second travel mode, characterized in that the electronic control unit is configured to make a gear shifting determination on whether to make gear shifting in the second travel mode in accordance with the gear shifting condition with a smaller amount of the hysteresis than the amount of the hysteresis in the first travel mode, and the electronic control unit is configured to suppress gear shifting by at least one of the upshift condition and the downshift condition more significantly in the second travel mode than in the first travel mode, in that, in the second travel mode, a gear shifting restriction period in which gear shifting is suppressed is extended, or a delay time until a gear shifting command is output is extended or a number of gear shifting determinations is increased. a drive power source (12;
