This steer-by-wire steering device is provided with: a steering input device; a steering device; a steering system includes a steering input device including a reaction force actuator that applies a steering reaction force to a steering operation input member, a steering device including a steering actuator that steers a steered wheel via a steering member, and a control device including: a reaction force actuator output amount reducing unit that reduces a steering force output amount of the steering actuator; when the deviation between the operation amount of the steering operation input member and the steering amount of the steering member increases and the vehicle speed of the vehicle increases, the output amount of the reaction force actuator is reduced. Therefore, even if the steering wheel collides with an obstacle when the vehicle speed is high, sudden shaking of the steering operation input component can be restrained.
本发明所涉及的线控转向式的转向装置具备:转向输入装置;转向装置;以及控制装置,所述转向输入装置具备对转向操作输入部件赋予转向反力的反力致动器,所述转向装置具备经由转向部件使转向轮转向的转向致动器,所述控制装置具备:反力致动器输出量减少部,在所述转向操作输入部件的操作量与所述转向部件的转向量的偏差增大且车辆的车速增大时,减少所述反力致动器的输出量。由此,即使在车速快时转向轮与障碍物发生碰撞等,也能够抑制转向操作输入部件突然晃动。
