To prepare lane information data having a high degree of reproduction of lane information at a spot at which the lane information data is needed according to an action plan of an own vehicle.SOLUTION: In a map data creation method by an on-vehicle control unit for preparing lane information data which is shown by point sequences obtained by arranging data points for defining latitude and longitude on a map and is used to reproduce lane information, information of a self position being the position of an own vehicle on the map is acquired (S1). Also, information of an action plan of the own vehicle V in a prescribed calculation section from the self position is acquired (S3). Then, a watching region is set in the calculation section on the basis of the action plan (S6). Lane information data of the calculation section is prepared by point sequences in which the interval of at least a portion of point sequences in the watching region is made narrower than the interval of point sequences in a non-watching region other than the watching region (S12).SELECTED DRAWING: Figure 3

    【課題】自車の行動計画に応じて必要となる地点での車線情報の再現度が高い車線情報データを作成する。【解決手段】地図上の緯度経度を規定するデータ点を並べた点列によって示され、車線情報を再現する際に用いる車線情報データを作成する車載制御ユニットによる地図データ作成方法において、地図上の自車の位置である自己位置の情報を取得する(S1)。また、自己位置からの所定の演算区間における自車Vの行動計画の情報を取得する(S3)。続いて、行動計画に基づいて演算区間内に注視領域を設定する(S6)。そして、注視領域の少なくとも一部の点列の間隔を、注視領域以外の非注視領域の点列の間隔よりも狭くした点列によって演算区間の車線情報データを作成する(S12)。【選択図】図3
