ABSTRACT:
A method of steering a vehicle along a predetermined, or real time path by using a steering control algorithm. The vehicle includes a navigation system and a navigation antenna. The navigation antenna is mounted on the vehicle at an optimum antenna position, whereas the steering control algorithm assumes a nominal antenna position at a predetermined reference point. The method comprises the following steps: (A) obtaining a set of positioning data of the vehicle by using the navigation system and by using the navigation antenna mounted at the optimum antenna position; (B) modifying the set of positioning data of the vehicle; (C) measuring a steering angle(s) of the front wheels of the vehicle relative to a predetermined reference direction(s); (D) calculating a correction(s) to the measured steering angle(s); and (E) performing a steering action by using the correction(s) to the measured steering angle(s) to move the vehicle along the predetermined, or real time path.
