Abstract: A control section of a steering controller calculates a steer angle which is a turning angle of a first column shaft based on a first detection value detected by a steer angle sensor, and calculates a second shaft turning angle which is a turning angle of a second column shaft based on a second detection value detected by a second shaft rotation angle sensor. A steering torque detection value is calculated based on a third detection value detected by a torque sensor. An abnormality determination part determines abnormalities of the steering torque detection value based on the steer angle and the second shaft turning angle. Thereby, abnormalities of the steering torque detection value are detected without multiplexing the steering torque detection value. Further, if the steering torque detection value is multiplexed, an abnormal steering torque detection value can be specifically identified.
