Abstract

A control device of an electric vehicle includes: a target rotation speed calculation unit that calculates a target rotation speed of a drive wheel based on a vehicle body speed; and a slip control unit that detects a slip of the drive wheel when a wheel speed exceeds the target rotation speed of the drive wheel and that controls motor torque of the motor in such a manner that the wheel speed becomes an appropriate rotation speed in detection of the slip. Further, the slip control unit controls the motor torque by feedback control according to a difference between the rotation speed of the motor and the target rotation speed of the drive wheel in detection of the slip.
