ABSTRACT:
An electrically driven steering apparatus is capable of continuing to detect a steering angle even if a rotation angle sensor is in trouble. The steering angle is acquired using three rotation angle sensors (first resolver35,second resolver37,motor resolver44). Thus, even if any resolver is in trouble, the steering angle can be detected continuously and by maintaining the functions of ABS, VSC and the like, the safety in traveling can be intensified.
