A steering system comprising: a steering shaft that rotates in accordance with an operation of a steering wheel , transmission of power between the steering shaft and turning wheels of a vehicle being cut off; a reaction motor configured to generate a steering reaction force that is a torque applied to the steering shaft in a direction opposite to a steering direction; and a control unit configured to control the reaction motor , wherein the control unit has a function of performing a correction process of rotating the steering wheel using the reaction motor such that a displacement in a rotational position of the steering wheel with respect to a correct rotational position corresponding to a turning position of the turning wheels decreases when a power supply of the vehicle is turned on and the rotational position of the steering wheel is different from the correct rotational position, the control unit is configured to perform the correction process when the displacement is equal to or greater than a predetermined permissible value and not to perform the correction process when the displacement is less than the permissible value, characterized in that: the correction process includes a first correction process of rotating the steering wheel such that the displacement becomes zero and a second correction process of rotating the steering wheel such that the displacement becomes the permissible value; and the control unit is configured to perform the first correction process when the displacement is greater than a predetermined limit value and to perform the second correction process when the displacement is equal to or greater than the permissible value and equal to or less than the limit value. a steering shaft that rotates in accordance with an operation of a steering wheel , transmission of power between the steering shaft and turning wheels of a vehicle being cut off; a reaction motor configured to generate a steering reaction force that is a torque applied to the steering shaft in a direction opposite to a steering direction; and a control unit configured to control the reaction motor , wherein the control unit has a function of performing a correction process of rotating the steering wheel using the reaction motor such that a displacement in a rotational position of the steering wheel with respect to a correct rotational position corresponding to a turning position of the turning wheels decreases when a power supply of the vehicle is turned on and the rotational position of the steering wheel is different from the correct rotational position, the control unit is configured to perform the correction process when the displacement is equal to or greater than a predetermined permissible value and not to perform the correction process when the displacement is less than the permissible value, characterized in that: the correction process includes a first correction process of rotating the steering wheel such that the displacement becomes zero and a second correction process of rotating the steering wheel such that the displacement becomes the permissible value; and the control unit is configured to perform the first correction process when the displacement is greater than a predetermined limit value and to perform the second correction process when the displacement is equal to or greater than the permissible value and equal to or less than the limit value. the correction process includes a first correction process of rotating the steering wheel such that the displacement becomes zero and a second correction process of rotating the steering wheel such that the displacement becomes the permissible value; and the control unit is configured to perform the first correction process when the displacement is greater than a predetermined limit value and to perform the second correction process when the displacement is equal to or greater than the permissible value and equal to or less than the limit value. <EOS>
