Abstract:
A method of maintaining vehicle formation includes receiving a desired along path distance; receiving a plurality of waypoints corresponding to a plurality of positions along a path of the lead vehicle; determining a dynamic path for the follower vehicle by spline fitting the plurality of positions of the plurality of waypoints; determining a commanded curvature of the follower vehicle based on a curvature of the dynamic path at a current position of the follower vehicle; determining a current along path distance between the lead vehicle and the follower vehicle; determining an along path error; determining a next speed of the follower vehicle based on the along path error and the respective waypoint speed of the respective waypoint that is adjacent to a current position of the follower vehicle; and outputting the commanded curvature and the next speed to a control system of the follower vehicle.
