The present invention relates to a method for fine positioning vehicles in exact relationships to geographic reference markings, whereby the vehicle (1) is adapted to fetch and deliver loads (2) preferably goods carried on loading stools or pallets, at fetching and delivering points (3-14), whereby it is required that the vehicle (1) repeatedly may be brought to exact positions relative to said fetching and delivering points (3-14) and whereby the vehicle (1) has at least one indicating and calculating device (24) for indicating the distance between two non-parallel lines (39-40) of the geographic reference markings (36) for calculating whether the vehicle (1) is on one side or the other of a certain relationship to a predetermined line (33 and/or 34) of direction of movement by indicating whether the distance measures between said lines (39, 40) of the reference marking is greater or smaller than the distance representing said certain relationship to the predetermined line (33 and/or 34) of direction of movement. In order to reach a quick fine positioning, the method is characterized by the fact that the vehicle (1), which by comprising separately operable driving wheels (15-18) with inclined ground contact means (19) is movable in optional directions by activating each driving wheel (15-18), is operated to drive in sideways direction (A or B) directly to the predetermined relationship to the predetermined line (33 and/or 34) of direction of movement and on the fetching and delivering point to an exact fetching and delivering position if the indcating and calculating device (24) indicates and calculates that the vehicle (1) is in relationships deviating from its predetermined relationship to the predetermined line (33 and/or 34) of direction of movement and on the fetching and delivering point in positions departing from the fetching and delivering position (FIG. 3). |
