First Claim
1. Method to assist steering of a vehicle equipped with an active steering system when operating in a reverse direction, comprising:
- monitoring vehicle operating characteristics and an operator steering input;
determining boundaries of a target region;
determining a reference point;
calculating a target steering angle range corresponding to the reference point and the target region;
determining a steering angle correction when the operator steering input is outside the target steering angle range; and
controlling the active steering system in response to the steering angle correction.

Abstract
A method to assist steering of a vehicle equipped with an active steering system when operating in a reverse direction is provided. The method comprises monitoring vehicle operating characteristics and an operator steering input. Boundaries of a target region and a reference point are determined. A target steering angle range is calculated based upon the reference point and the target location. A controlled steering angle of the active steering system is corrected when the operator steering input is outside the target steering angle range. An aspect of the invention included determining the reference point comprising a point of intersection of a first vector and a second vector, the first vector parallel to and passing through a centerline of a rear axle of the vehicle and the second vector perpendicular to and passing through a centerline of an inside front steerable wheel of the vehicle.
