Apparatus and method of diagnosing and correcting steering angle of steer-by-wire steering system

Abstract

A steering angle diagnosis and correction apparatus and method in a steer-by-wire (SBW) steering system including a sensor unit configured to detect information for diagnosing a steering angle alignment error between a steer-side upper system and a wheel-side lower system in the SBW steering system through a plurality of sensors provided in the upper and lower systems, and a plurality of processors configured to execute one or more instructions to diagnose the steering angle alignment error between the steer-side upper system and wheel-side lower system on a basis of the information detected by the sensor unit and correct the steering angle alignment error in real time.
