Abstract:
There is provided a control device for an electric power steering device, which determines an estimate of a steering angle instead of using an angle sensor when any abnormality is detected in the angle sensor to perform steering angle control using the determined estimate of the steering angle. When it is determined that the detected steering angle is normal based on a steering angle abnormality determination signal Flg_θh, a steering angle calculating section  201  outputs a steering-wheel angle θh as an actual steering angle θr, while when it is determined that the detected steering angle is abnormal, the steering angle calculating section  201  determines and outputs an estimate θr of an actual steering angle using a past value Zθr of the actual steering angle under normal conditions, a motor relative angle Δθm, and a relative twist angle Δθ of a torsion bar.

Claim (Index 3):
The control device for the electric power steering device according to  claim 2 , wherein when the steering angle abnormality determination signal indicates abnormal, the steering angle calculating section uses a past value Z\u03b8r of an actual steering angle under normal conditions, a motor relative angle \u0394\u03b8m, and a relative twist angle \u0394\u03b8 of a torsion bar to derive the actual steering angle estimate \u03b8r.
