| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a control device for an electric power steering device capable of safely switching an output value of a torque sensor and a substitution value used at the abnormal state even when a plurality of torque abnormality detection means exist. SOLUTION: When the time for continuously selecting substitution value control is a predetermined time T3 or longer and when the substitution value is not renewed for a predetermined time T2, it is determined that the torque sensor 107 is failed and the substitution value control is stopped.
