This steering device is provided with: a steering input device that is provided with a reaction force actuator that applies a steering reaction force to a steering operation input member; the control device is provided with: a steering gear ratio variable unit that varies the steering gear ratio in accordance with the vehicle speed; a reaction force actuator control unit that controls the output amount of the reaction force actuator in accordance with the operation angular velocity of the steering input member; and a reaction force actuator output variable unit that varies the output of the reaction force actuator on the basis of the steering gear ratio. As a result, the steering reaction force applied to the steering input member can be appropriately set, and the operation load of the driver can be stably suppressed.
本发明的转向装置具有:转向输入装置,其具备反作用力致动器,该反作用力致动器向转向操作输入部件施加转向反作用力;控制装置,其具备:转向齿轮比可变部,其使转向齿轮比根据车速可变;反作用力致动器控制部,其根据转向操作输入部件的操作角速度控制反作用力致动器的输出量;反作用力致动器输出量可变部,其使反作用力致动器的输出量基于转向齿轮比可变。由此,能够适当地设定施加给转向操作输入部件的转向反作用力,稳定地抑制驾驶员的操作负荷。
