Zusammenfassung:To provide an altitude estimation method and altitude estimation device that can highly accurately estimate an altitude, and also to provide a tire management method and tire management device that use information on the estimated altitude.SOLUTION: An altitude estimation method, which is the altitude estimation method that an altitude estimation device estimating an altitude implements, includes: a first acquisition step (S1) of: acquiring location actual data indicative of a three-dimensional location where a mining vehicle moves; a preparation step (S2) of preparing a map for grasping topography based on an average value or center value of an altitude relative to a longitude or latitude of the location actual data; a correction step (S3) of making a correction so as to be a route allowing the mining vehicle to move in an aspect of a difference of the altitude; a second acquisition step of acquiring location data on a specific vehicle serving as one of the mining vehicle; and a calculation step of calculating an altitude corresponding to the location data on the specific vehicle on the basis of the map for grasping the topography.SELECTED DRAWING: Figure 3 【課題】標高を高精度に推定可能な標高推定方法及び標高推定装置、また、推定された標高情報を用いたタイヤ管理方法及びタイヤ管理装置が提供される。【解決手段】標高推定方法は、標高を推定する標高推定装置が実行する標高推定方法であって、鉱山車両が移動した3次元の位置を示す位置実績データを取得する第1取得ステップ(S1)と、位置実績データの経度及び緯度に対する標高の平均値又は中央値に基づいて地形把握用地図を作成する作成ステップ(S2)と、地形把握用地図の標高について標高差の観点で鉱山車両が移動可能な経路となるように補正を行う補正ステップ(S3)と、鉱山車両のうちの1つである特定車両の位置データを取得する第2取得ステップと、地形把握用地図に基づいて特定車両の位置データに対応する標高を算出する算出ステップと、を含む。【選択図】図3
