<p>Steering system which does not cause the driver to feel the steering reactive force shock when the operation of the steering wheel is stopped, and which enables the driver to operate the steering wheel comfortably.
In order to achieve the above object, there is provided a steering system in which a transfer ratio of a steering angle of a steering wheel to a turning angle of a turning wheel is changed by a variable transfer ratio mechanism, and an auxiliary power is generated during steering by an electric power steering, including: a transfer ratio variable motor for changing the transfer ratio, in which a steering angular velocity of the steering wheel is calculated, and when an absolute value of the steering angular velocity becomes equal to or less than a predetermined value, a current value flowing through the transfer ratio variable motor is set to zero.</p> |
