Path control system
First Claim
1. A system for controlling from a path of a first vehicle a second vehicle to follow a complementary path, the system comprising:
- a first vehicle sub-system having;
a memory for time (T) and (X,Y) position co-ordinates of the first vehicle'"'"'s path;
a GPS receiver for determining time (T) and actual (X,Y) position co-ordinates of the first vehicle,means for comparing the first vehicle'"'"'s actual position with path position at determined times as test path errors andmeans for transmitting the test path errors anda second vehicle sub-system having;
a memory for time (T) and (X,Y) position co-ordinates of the second vehicle'"'"'s path;
a GPS receiver for determining time (T) and actual (X,Y) position co-ordinates of the second vehicle,means for receiving the test path errors andmeans for computing a modified path of the second vehicle taking account of the test path errors and generating control signals for controlling the second vehicle to follow the modified path, whereby the first vehicle and the second vehicle'"'"'s travel along actual paths which are complementary to each other in like manner to the memorised paths;
wherein the memories of the first and second vehicle sub-systems are adapted to memorise the respective paths as waypoints, each having (X,Y,T) co-ordinates.
