  • Patent number: 6834220
    Abstract: The invention relates to a self-propelling vehicle which first, and possibly with the aid of a driver, drives along a selected route from a starting point to a destination, whereby the vehicle receives position signals from a positioning system and stores said signals in a data memory. The vehicle first receives an associated current position signal from the positioning system and at a point of departure when the vehicle subsequently and automatically drives along exactly the same selected route. Said signal is compared to the position of the starting point. If the positions do not match, the evaluation device calculates the direction towards and the distance to the starting point, whereupon the vehicle drives along this route. The direction and the distance to the next stored position are subsequently calculated using successively received current position data. The vehicle drives along the corresponding route.
