Abstract:
    A matching method of distributed map includes carrying out the first time of dividing to divide complete positioning region to be N ( N is greater than or equal to 1) sub-regions along one-dimensional direction, dividing original GPS data as per divided sub-regions for making each sub-region obtain partial GPS data, carrying out the second time of dividing to divide each sub-region to be M ( M is greater than or equal to 1) map check then making match-positioning and carrying out calculation on degree of correlation for selecting one road section with maximum degree of correlation as positioned road section being used as driving road section.
