FOLLOWER VEHICLE CONTROL SYSTEM AND METHOD FOR FORWARD AND REVERSE CONVOY MOVEMENT
First Claim
1. A vehicle control system for causing a follower vehicle to follow a leader, comprising:
- a tether system operatively associated with a leader and a follower vehicle;
a path tracking system operatively associated with the tether system, the path tracking system determining a path traveled by the leader;
a path control system operatively associated with the path tracking system, the path control system causing the follower vehicle to travel to a traveled point on the path traveled by the leader.

Abstract
A vehicle control system for causing a follower vehicle to follow a leader may have a tether system mounted to the follower vehicle. The tether system may include a tether having an end adapted to be attached to the leader, a length sensor, and an angle sensor. A path tracking system operatively associated with the tether system determines a path traveled by the leader. A path control system operatively associated with the path tracking system and the follower vehicle causes the follower vehicle to follow the path traveled by the leader. A spacing control system operatively associated with the path tracking system and the follower vehicle causes the follower vehicle to maintain a predetermined spacing between the follower vehicle and the leader.

18. A method for causing a follower vehicle to follow a leader, comprising:
-
connecting the follower vehicle to the leader with a tether; measuring a length of the tether connecting the follower vehicle to the leader; measuring an angle between the tether and the follower vehicle; determining a position of the leader based on the measured length and the measured angle; determining a path traveled by the leader based on a plurality of determined leader positions; determining a determined path for the follower vehicle from an actual position of the follower vehicle and a selected travel point on the path traveled by the leader; steering the follower vehicle so that the follower vehicle substantially follows the determined path for the follower vehicle; and controlling a velocity of the follower vehicle so that the follower vehicle maintains a predetermined distance from the leader. - View Dependent Claims (19, 20, 21, 22, 23)
