US 12,709,328 B2 · Steering control apparatus of steer-by-wire system and steer wheel feedback actuator compliance monitoring method thereof

Abstract

A steering control apparatus of a steer-by-wire system including a steer wheel feedback actuator and a road wheel actuator includes a controller configured to receive a first angle value from a first sensor provided at a lower steering shaft, connected to a steering wheel through an upper steering shaft and receive a second angle value from a second sensor provided at a motor of the steer wheel feedback actuator, and monitor compliance of the steer wheel feedback actuator using the first angle value and the second angle value based on determination of whether at least one of torque, a driving speed, and a steering angle of the steering wheel satisfies at least one preset condition for checking the compliance of the steer wheel feedback actuator.
