The invention relates to a steering control device of a steer-by-wire system. A steering feedback unit detects a steering torque generated according to an operation of a steering wheel, and a loading wheel steering unit connected to the steering feedback unit allows steering of wheels to be performed according to a steering angle or the steering torque transmitted from the steering feedback unit. And the control unit selectively determines the steering torque detected in the steering feedback unit as a steering angle according to a preset standard vehicle speed and a standard steering speed so as to transmit the determined steering angle to the loading wheel steering unit, and controls execution of steering of the wheels according to the steering angle. Or the steering torque detected in the steering feedback unit is transmitted to the road wheel steering unit, and the determination of the amount of motor torque for controlling wheel steering is controlled.
本申请涉及线控转向系统的转向控制装置。转向反馈单元检测根据方向盘的操作生成的转向扭矩,连接到转向反馈单元的负重轮转向单元允许根据从转向反馈单元传递的转向角或转向扭矩执行车轮的转向,以及控制单元根据预设标准车速和标准转向速度选择性地将转向反馈单元中检测到的转向扭矩确定为转向角,以将确定的转向角传递给负重轮转向单元,并且根据转向角控制车轮的转向的执行,或者将转向反馈单元中检测到的转向扭矩传递给负重轮转向单元,并且控制车轮转向的电机扭矩的量的确定。
