Abstract
A turning control device includes a terminal position learning unit configured to learn a terminal position of the turning mechanism, based on a steered position of the turning mechanism detected by a position detection unit, a command value correction unit configured to, when a steered position detected by the position detecting unit is in a vicinity of a learned terminal position, correct a current command value for an actuator providing a turning mechanism with steering assist force, and a correction amount limiting unit configured to limit a correction amount of the current command value by the command value correction unit, based on a comparison result between the learned terminal position and a predetermined position and a comparison result between stroke length of the turning mechanism calculated from the learned terminal positions and a predetermined length.
