Control device for electric vehicle

A control device for an electric vehicle including a drive motor of which magnetic poles of a rotor are comprised of variable magnetism magnets that are able to change magnetism, and a clutch disposed between the drive motor and driving wheels, the electric vehicle being travelable using electric power, the control device being configured to:

• when the electric vehicle travels, perform a torque control in which a motor torque outputted from the drive motor is controlled so that the motor torque coincides with a demanded torque demanded to be outputted to the driving wheels, and a first clutch control in which an engaging torque of the clutch is controlled to be higher than the demanded torque;
• and
• when performing a magnetization control in which the magnetism of the variable magnetism magnets is changed to magnetize the variable magnetism magnets when the electric vehicle travels:
• change a 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
• add a given slip torque to the demanded torque based on a coefficient of dynamic friction and a coefficient of static friction of the clutch to start a micro slip control in which the clutch is transitioned from an engaged state into a micro slip state.
