APPARATUS FOR CONTROLING STEERING FOR VEHICLE

摘要

The present invention relates to a steering control device for a vehicle. The steering control device for a vehicle includes an EPS unit which is coupled to a steering shaft which is combined with a steering wheel, and generates a driving force for rotating the steering wheel; an encoder which detects a steering angle at which an electric motor of the EPS unit is rotated and transmits the detected steering angle to a control unit; and the control unit which controls the electric motor of the EPS unit in response to the steering angle transmitted from the encoder, wherein the control unit receives, from the encoder, the steering angle at which the electric motor is rotated and controls the EPS unit in real time. According to the present invention, the steering control device for a vehicle can prevent locking of a steering wheel caused by malfunction of an MDPS ECU when the electric motor is controlled through a conventional MDPS ECU, and can prevent an increase of a steering error when the electric motor is controlled through the conventional MDPS ECU.
