Method for fine positioning vehicles in exact relationships to geographic reference markings

摘要

The present invention relates to a method for fine positioning vehicles in exact relationships to geograpic 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 geograpic 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. In order to reach a quick fine positioning, the vehicle (1), comprising separately operable driving wheels (15-18) with inclined ground contact means (19) movable in optional direc­tions by activating each driving wheel (15-18), is operated to drive in sideways direction (A or B) following the results of the indicating and calculating device (24) to reach an exact the fetching and delivering position.
