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 a turning mechanism detected by the position detection unit; and a relearning determination unit configured to determine necessity of relearning of the terminal position. The relearning determination unit includes: an end-abutting detection unit configured to detect occurrence of end-abutting, and acquire an end-abutting steering angle that is a steering angle when end-abutting is occurred; an end-abutting steering angle range determination unit configured to determine whether or not variation in the end-abutting steering angles acquired multiple times is less than or equal to a predetermined threshold value; and a relearning unit configured to, when the variation is less than or equal to the predetermined threshold value, reset the learned terminal position to an initial value.
