Abstract
A steering device includes: a variable actuator capable of changing an angle ratio between a steering angle of a steering wheel and a turning angle of a turning wheel; a steering auxiliary mechanism arranged between the variable actuator and the turning wheel to apply steering auxiliary force to a steering mechanism; a torque angle sensor to detect steering torque to be inputted into the steering mechanism. The steering auxiliary mechanism is driven such that the steering auxiliary force in accordance with the steering torque is generated, and, when an avoidance instruction is inputted, an automatic steering control is performed to drive-control the steering auxiliary mechanism so as to run at the turning angle specified by steering position instruction to be inputted. The angle ratio of the variable actuator is adjusted so as to suppress reaction force to be transmitted to the steering wheel by performing the automatic steering control.
