Abstract
A control device for an electric vehicle which is able to accurately control a traction motor of the electric vehicle without any delay in control timing during rapid acceleration or rapid deceleration of the motor, is provided. The control device for the electric vehicle includes an ECU and an inverter device including a motor control module. A rotation angle sensor configured to detect a rotation angle of a motor is provided, and the motor control module is provided with a rotation angle correction section configured to correct a rotation angle of a rotor of the motor which is used for vector control, by using an angular speed of an electrical angle which is the rotation angle detected by the rotation angle sensor and a differential value of the angular speed of the electrical angle.
