Vehicle steering apparatus

摘要

A control ON/OFF determination unit (67) determines that oversteer control should be started in the case where a slip angle differential value (d¸sp) is equal to or greater than a predetermined threshold value, the sign of the slip angle differential value (d¸sp) is identical with the sign of a yaw rate (Ry), the sign of a steering wheel turning angle (¸s) is identical with the sign of a steering wheel turning speed (És), and a vehicle speed (V) is equal to or greater than a predetermined threshold value.
