Abstract
For a motor vehicle , a method for generating a map of a vehicle's dynamic steering ratio as a function of vehicle velocity and yaw rate. The steering ratio accounts for vehicle system compliance during dynamic maneuvers. The mapping of the steering ratio is used in an algorithm to estimate the vehicle's steering wheel angle while the vehicle is in a dynamic maneuver such as a turning maneuver. This estimation is based on the front wheel steer angles that are derived from the yaw rate and longitudinal velocity and the steering ratio.
