There is provided an electric power steering apparatus capable of dealing with abnormality when the abnormality happens in the torque, without being affected by an abnormal torque signal and without giving the driver a feeling of strangeness. Abnormality is detected with a double detection configuration including a main ECU clip (34) and a sub ECU interlock (61). Then when abnormality is detected in steering torque (Ti) detected by a torque sensor (3), the input of a main ECU clip (34) is switched from the steering torque (Ti) detected by the torque sensor (3) to a torque alternative value, and the input value of the sub ECU interlock (61) is switched from a steering assist command value subjected to limiting at the main ECU clip (34) to zero. |
