Abstract: The present invention relates to an autonomous steering system of a tractor and comprises; a steering unit which is made of a steering wheel and a steering axis combined to the steering wheel; an MDPS which rotates the steering wheel by being combined to the lower part of the steering axis and by determining a steering angle; an orbit roll which supplies oil pressure to a steering cylinder assembled to a wheel assembling part by being combined to the lower part of the MDPS and rotates a wheel by the steering cylinder with the oil pressure of an oil pressure pump; and a control device part which integrally manages the whole system of the tractor by being combined to the back side of the tractor. The MDPS comprises; an electric motor which provides driving force for the rotation of the steering wheel; and an ECU which controls the driving of the electric motor by transmitting and receiving steering wheel data through CAN communication with the control device part. According to the present invention, the autonomous steering system facilitates autonomous driving of the tractor and provides a precise autonomous driving effect of the tractor by mounting a potential meter.

Abstract: 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.
