This steer-by-wire control device is provided with a control device (19) for controlling a first motor (18) for operating a steering wheel (12) of a vehicle and a second motor (35) for controlling the steering operation of wheels. Before a vehicle shifts to an automatic driving mode, a control device (19) applies an input torque to a steering wheel (12) in a forward rotation direction and a reverse rotation direction of a first motor (18) by means of the first motor (18) (S11), acquires behavior information of the steering wheel (12) obtained by applying the input torque (S12), and determines whether or not to estimate a control parameter of the steering wheel (12) on the basis of the behavior information (S15-S16). The behavior information includes at least one of a value of a rotation angle of the steering wheel and a value obtained by time-differentiating the rotation angle. 本发明的线控转向控制装置包括控制装置(19)，该控制装置(19)控制使车辆的方向盘(12)动作的第一电机(18)和控制车轮的转向动作的第二电机(35)。控制装置(19)在车辆转移至自动驾驶模式前，通过第一电机(18)对在第一电机(18)的旋转方向的正转方向和反转方向
