Steering system

A steering system of steer-by-wire type, comprising:

• an operation device including an operation member for a steering operation by a user and a reaction force application device configured to apply an operation reaction force to the operation member;
• a turning device mechanically cut off from the operation device and configured to turn a wheel according to a control current supplied;
• and
• a controller configured to control the turning device and the reaction force application device based on an operation signal relating to an action of the operation member received from the operation device, wherein:
• the steering system is configured to switch between a normal mode of turning the wheel based on the operation signal and a virtual mode of steering a virtual mobile body, created as a video image, based on the operation signal;
• the controller is configured to receive an accelerator signal relating to an action of an accelerator operation member for an accelerator operation that is provided in a vehicle, and a brake signal relating to an action of a brake operation member for a brake operation that is provided in the vehicle;
• and
• in the virtual mode, the controller is configured to
• set the control current to a current value at which the wheel does not turn regardless of the operation signal, and
• set the operation reaction force based on the operation signal and the accelerator signal or based on the operation signal and the brake signal.
