<p>A steering system (100) includes: an electric power steering device (110) which includes a steering unit of front wheels (1) having an electric motor (4) for generating an auxiliary torque in accordance with at least a steering torque and for transmitting the auxiliary torque to the steering unit; toe angle changers (120) for changing toe angles of rear wheels (2) in accordance with at least a front wheel turning angle and a vehicle speed; and a steering controller (130) for controlling the electric power steering device (110) and the toe angle changer (120). The steering system (100) further includes a toe angle changer anomaly detection unit (81d) and/or an electric power steering device anomaly detection unit (272), and when a toe angle changer abnormal state is detected, an auxiliary torque target value and/or a viscosity in the electric power steering device (110) is controlled, and when an electric power steering device abnormal state is detected, the toe angle changer (120) is controlled.</p> |
