  • Patent number: 4984168
    Abstract: In a method for determining a route between a starting point and a destination which are located on a digitally memorized road map, the problem is to perform the necessary calculations for determining the route within a short time, even for extensive road systems. Otherwise, the results could arrive too late and could no longer lend the driver any aid in making a decision. The object is attained by dividing the road map into at least two levels of different grid density and regional size and storing it in memory. A plurality of smaller subregions of fine grid density are assigned to the lower level, and one or more larger subregions of coarser grid density are assigned to the higher level. Beginning with the lower level of the road map, a possible route is then studied; if the results are negative, a transition is made to the next-higher level, until a positive result is attained.
