Method of steering a machine on a predetermined route and device for its execution
First Claim
1. A method for steering an agricultural machine on a predetermined off-road route comprising:
- determining an actual position of an agricultural machine;
pre-determining a maximum angle at which the agricultural machine may be turned, wherein any change in direction that exceeds the pre-determined maximum angle is a big change in direction;
comparing the actual position relative to a desired position of the agricultural machine wherein the desired position is located on a predetermined off-road route;
transmitting steering controls to the agricultural machine if a difference between the actual position and the desired position exceeds a certain quantity wherein the control commands cause the agricultural machine to be steered to a new future position on the predetermined route via an unconstrained path, different from the predetermined route, based upon a future segment of the predetermined off-road route;
wherein the machine'"'"'s return to the new future position is effected on a return way which minimizes a divergence from the predetermined off-road route as well as avoiding big changes of direction in an actual path of travel; and
wherein by means of control commands, the machine'"'"'s direction of motion is, already before the new future position, adapted to the direction of the predetermined off-road route to be traveled after reaching the new fixture position.

Abstract
The invention discloses a method of steering a machine, in particular an agricultural machine, on a predetermined route, where, by means of an actual position detecting means, the actual position of the machine is detected and is, by means of a comparator, compared to a desired position, wherein, if there is a difference between the actual position and the desired position exceeding a certain quantity, control commands are transmitted to the machine to return same to the predetermined route on a return way, wherein, according,to the invention, an optimum return way is determined in consideration of the predetermined route which still has to be traveled in the further course and corresponding control commands are transmitted to the machine, which return the machine to a desired position of the predetermined route on the optimum return way.
