1. A method of calculating a feed-forward lateral acceleration of a moving vehicle comprising the steps of:
- measuring a speed of the moving vehicle;
measuring a steering angle of the moving vehicle;
calculating an Ackerman steer angle of the moving vehicle;
calculating a corrected steering angle of the moving vehicle using the Ackerman steer angle of the moving vehicle; and
calculating the feed-forward lateral acceleration of the moving vehicle using the measured speed of the moving vehicle and the corrected steering angle.

Abstract
A method of calculating feed-forward lateral acceleration of a moving vehicle is provided. The method includes the use of a corrected steering angle of the vehicle. The steering angle is corrected by using the Ackerman steer angle of the vehicle. Depending upon the speed at which the vehicle is traveling the steering angle may be corrected using the full Ackerman steer angle, a fraction of the Ackerman steer angle or not at all.
