Title:
ELECTRIC-VEHICLE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/199878
Kind Code:
A1
Abstract:
Provided is an electric-vehicle control device capable of effectively controlling a drive motor of an electric vehicle, without any delay in control timing during sudden acceleration and sudden deceleration of said motor. This electric-vehicle control device is provided with: an ECU (21); and an inverter device (22) provided with a motor control unit (29). A rotation-angle sensor (36) for detecting the rotation angle of a motor (6) is provided. The motor control unit (29) is provided with a rotation-angle correction unit (38) which uses the angular velocity of an electrical angle, i.e. the rotation angle detected by the rotation-angle sensor (36), and a differential value of the angular velocity of the electrical angle, to correct the rotation angle of a rotor of the motor (6), said rotation angle being used for vector control.
