Abstract:
1. A method of steering a vehicle along a predetermined 2-D path on a 2-D plane by using a steering control algorithm, said vehicle including a single navigation system and including a navigation antenna, said navigation antenna being mounted on said vehicle at an optimum antenna position, said steering control algorithm assuming a nominal antenna position at a predetermined reference point; said method comprising the steps of: (A) obtaining a set of positioning data of said vehicle by using said single navigation system and by using said navigation antenna mounted at said optimum antenna position; (B) pre-adjusting said set of positioning data obtained in said step (A) and feeding said pre-adjusted set of positioning data into said steering control algorithm; (C) measuring a steering angle of the front wheels of said vehicle relative to a predetermined reference direction on said 2-D plane; (D) calculating a correction to said measured steering angle on said 2-D plane; and (E) performing a steering action by using said correction to said measured steering angle on said 2-D plane in order to move said vehicle along said predetermined 2-D path on said 2-D plane.
