Abstract: In a steering system including a steering operation mechanism, a second actuator, a steering angle sensor, a steering torque sensor, and a steering operation control device and a control method for the steering system, only a drive assist target steered angle (first target steered angle) is reflected in a final target steered angle when a torque sensor value (actual steering torque) detected by the steering torque sensor is equal to or less than an intervention threshold. When the magnitude of the torque sensor value is more than the intervention threshold, the rate of reflection (distribution ratio) of a driver target steered angle (second target steered angle) in the final target steered angle is raised as the torque sensor value is increased, and the rate of reflection of the driver target steered angle in the final target steered angle is lowered as the magnitude of the torque sensor value is decreased.
