A steering control device, a steering control method, and a steering-by-wire system according to the present invention, in a steering-by-wire system having a first actuator for applying a torque to a steering operation input member and a second actuator for applying a steering force to a wheel, when the system is turned on, the steering force is applied to the wheel by the first actuator, and the steering force is applied to the wheel by the second actuator. When the amount of deviation of the steering angle of the wheel with respect to the operation position of the steering operation input member is equal to or greater than a permissible amount, the first actuator is controlled so that the amount of deviation becomes smaller when the vehicle speed is equal to or less than a threshold value. When the vehicle speed is greater than the threshold value, the second actuator is controlled so that the deviation amount becomes smaller. As a result, it is possible to suppress adverse effects on vehicle maintenance and vehicle travel by control that matches the operation position and the steering angle.

    本发明的转向控制装置、转向控制方法以及线控转向系统在一个方案中,在具有向转向操作输入部件施加转矩的第一促动器和向车轮施加转向力的第二促动器的线控转向系统中,在系统开启时,在车轮的转向角相对于转向操作输入部件的操作位置的偏差量为容许量以上的情况下,在车速为阈值以下时以使所述偏差量变小的方式对第一促动器进行控制,在车速比所述阈值大时以使所述偏差量变小的方式对第二促动器进行控制。由此,能够抑制使操作位置与转向角一致的控制给车辆维保和车辆行驶带来不良影响。
