Patent ID: 8738238

Claim:
A controller comprising: a first communication interface to a first vehicle for determining a path of the first vehicle; a second communication interface to a number of other vehicles to communicate a number of parallel paths that are substantially parallel to, and offset to at least one of a first and second offset side of, the path for the first vehicle; control logic, responsive to first data indicative of a turn in the path of the first vehicle, for signaling the number of other vehicles through the second communication interface to move onto at least a portion of the path in the turn; and control logic, responsive to second data indicative of the first vehicle completing the turn, for signaling the number of other vehicles through the second communication interface to move from the path to a number of second parallel paths that are substantially parallel to the path after the turn of the first vehicle, and offset to an opposite side of the path of the first vehicle, than the at least one of the first and second offset side of the path before the turn.
