Claim 0:
1. A system comprising:
a memory having a set of computer-executable instructions stored thereon; and
a processor communicable with the memory and an on-vehicle device of at least one vehicle, wherein
the set of computer-executable instructions stored on the memory cause the processor to implement:
detecting whether a number of characteristic information items consistent between characteristic information included in probe data of vehicle surroundings and characteristic information included in a corresponding data block of map data is equal to or greater than a number of data items enough for three-dimensional identification of the probe data;
determining that the probe data does not include sufficient characteristic information usable for alignment with the map data in response to detecting that the number of characteristic information items consistent between the characteristic information included in the probe data and the characteristic information included in the corresponding data block of the map data is smaller than the number of data items enough for three-dimensional identification of the probe data;
joining a target probe data set including the probe data that does not include sufficient characteristic information to a probe data set that is previous or subsequent to the target probe data set in consecutive probe data sets, the consecutive probe data sets comprising a plurality of probe data sets acquired from the at least one vehicle during traveling from engine start to engine stop;
updating the map data based on the joined probe data sets; and
transmitting the map data updated based on the joined probe data sets to the on-vehicle device, the map data includes a travel path model,
wherein
the at least one vehicle is configured to follow travel paths of the travel path model during autonomous driving of the at least one vehicle.
