Abstract
An electric vehicle includes front and rear wheels, a battery, an electric motor that drives at least one of the front and rear wheels, an accelerator, and a mode shift operator that is operated by a user in order to switch drive modes. The electric vehicle includes a driving force characteristics setter that sets, for each of the plurality of drive modes, driving force characteristics which are characteristics of an accelerator opening degree and a target motor driving force for the rotational speed of the electric motor. The electric vehicle further includes a controller which shifts up, according to an operation of the mode shift operator, the drive mode from a first drive mode to a second drive mode and which controls the target motor driving force according to the driving force characteristics. When a shift-down prohibition condition is met, the controller prohibits a shift down from the second drive mode to the first drive mode.
