A control device for an electric vehicle is provided, which includes a drive motor of which magnetic poles of a rotor are comprised of variable magnetism magnets, and a clutch disposed between the drive motor and driving wheels. When the electric vehicle travels, the control device performs a torque control, and a first clutch control in which an engaging torque of the clutch is controlled to be higher than a demanded torque. When performing a magnetization control when the electric vehicle travels, the control device changes the clutch control from the first clutch control to a second clutch control in which the engaging torque is made to coincide with the demanded torque, before the execution of the magnetization control, and adds a given slip torque to the demanded torque to start a micro slip control in which the clutch is transitioned from an engaged state into a micro slip state.
