Abstract
In a steering control apparatus, a worm gear is configured to have a lead angle for a self-lock operation, by which a worm wheel is allowed to rotate by rotation of a worm but the worm is not allowed to rotate by rotation of the worm wheel. Thus, a lock mechanism need not be provided separately from a gear mechanism and the apparatus is reduced in entire size. A VGRS control part checks whether the worm gear has a self-lock failure, which disables the self-lock operation. If the worm gear has the self-lock failure, idling suppression processing is performed to suppress idling of a steering wheel. Thus, even when the self-lock failure arises, the steering wheel is suppressed from idling.
