Abstract
The embodiments may provide a steering control device of a vehicle equipped with a steer-by-wire steering system and a rear wheel steering system. A steering control device may include a sensor configured to acquire information on the vehicle, and a controller configured to, in response to a determination of a failure of the steer-by-wire steering system, determine a target yaw rate according to a target steering angle based on the information acquired from the sensor, and generate and output a differential braking control signal and a rear wheel steering control signal to follow the target yaw rate.

A steering control device of a vehicle equipped with a steer-by-wire steering system and a rear wheel steering system, comprising:
- a sensor configured to acquire information on the vehicle;
- and
- a controller configured to, in response to a determination of a failure of the steer-by-wire steering system, determine a target yaw rate according to a target steering angle based on the information acquired from the sensor, and generate and output a differential braking control signal and a rear wheel steering control signal to follow the target yaw rate,
- wherein the controller generates the rear wheel steering control signal based on the target yaw rate and outputs the rear wheel steering control signal to the rear wheel steering system, and generates the differential braking control signal for following the target yaw rate and outputs the differential braking control signal to a braking system,
- wherein the controller generates and outputs the rear wheel steering control signal to the rear wheel steering system during a reference time period, and generates and outputs the differential braking control signal to the braking system after the reference time period to produce a larger and smoother steering motion.
