Abstract: A steer-by-wire type steering apparatus includes a steering input device; a steering device; and a control device. The steering input device includes a reaction force actuator configured to apply steering reaction force to a steering operation input member. The steering device includes a steering actuator configured to cause steered road wheels to be steered through a steering member. The control device includes a reaction force actuator output amount decrease unit configured to decrease an output amount of the reaction force actuator when a deviation between an operation amount of the steering operation input member and a steering amount of the steering member increases and vehicle speed of a vehicle increases. This can prevent the steering operation input member from being abruptly moved in spite of a collision of the steered road wheels with an obstacle or other factors at the time of high vehicle speed.

Abstract: A steering input device for steer-by-wire, according to the present invention, includes a steering shaft that is mechanically separated from a steered wheel, a reaction force motor that applies a steering load to the steering shaft, a lock mechanism that regulates rotation of the steering shaft, a steering amount sensor that detects an operation amount of the steering shaft and outputs an operation amount signal, and a controller.
