1. A vehicle control system comprising:
a road wheel angle sensor configured to detect a road wheel angle;
a steering feedback motor configured to rotate a steering wheel in response to the road wheel angle and to generate a steering torque value in response to a physical rotation of the steering wheel by a vehicle driver;
a processor configured to receive the road wheel angle and the steering torque value, to estimate a steering wheel angle in response to the steering torque value and to generate a validated steering angle in response to a difference between the road wheel angle and the steering wheel angle being less than a threshold value; and
a steering controller configured to control the steering of a vehicle in response to the validated steering angle.
