To effectively reduce a data volume in generating route information and thereby enable automatic driving to be smoothly executed.SOLUTION: This route generating device comprises: a vehicle position estimation unit for acquiring the absolute position coordinates of a vehicle acquired from a GNSS system and estimating the relative position of the vehicle with respect to the absolute position coordinates; a route information conversion unit for receiving first route information and converting the first route information into second route information by matching the first route information with high-precision map data; and a map information output unit for outputting map information on the basis of the relative position, the high-precision map data and the second route information. The route information conversion unit discriminates information that relates at least to a main route through which the vehicle is scheduled to pass and information that relates to a sub-route for which the probability of the vehicle passing through is smaller than for the main route in the first information, executes first data processing for the main route, and executes second data processing for the sub-route.SELECTED DRAWING: Figure 2

    【課題】経路情報の生成におけるデータ量を効果的に削減し、これにより自動運転を円滑に実行することを可能にする。【解決手段】この経路生成装置は、GNSSシステムから取得された車両の絶対位置座標を取得するとともに、絶対位置座標を基準として車両の相対位置を推定する自車位置推定部と、第1経路情報を受信して、第1経路情報を高精度地図データとマッチングすることにより第1経路情報を第2経路情報にデータ変換する経路情報変換部と、相対位置、高精度地図データ、及び第2経路情報に基づき地図情報を出力する地図情報出力部とを備える。経路情報変換部は、第1経路情報において、少なくとも車両が通行する予定の主経路に関する情報と、主経路よりも前記車両が通行する確率が小さい副経路に関する情報とを識別し、主経路に対し第1のデータ処理を実行し、副経路に対し第2のデータ処理を実行する。【選択図】図2
