Steering control system and steering control method

Abstract

A steering control system that controls a steering device of a vehicle includes a storage unit, and a control unit configured to make a state transition to a normal control state via a start-up state after a power source system of the vehicle is started. In the start-up state, the control unit executes a correction information storing process of acquiring correction element information using a state variable obtained from the steering device and writing correction information obtained based on the correction element information into the storage unit. In the start-up state, the control unit is configured to execute an abnormal condition determination process of determining whether an abnormal condition indicating that the correction information is abnormal is met. The correction information storing process is re-executed when the abnormal condition is met. The abnormal condition determination process is executed at least either before or after the correction information storing process.
