PROBLEM TO BE SOLVED: To provide a wireless data-updating method for a database of an on-vehicle device, which prevents data garbled by transmission from being installed in the database of an on-vehicle device as update data.SOLUTION: A wireless data-updating method comprises: a step S104 where a ground device wirelessly transmits ground side update data B 1 to an on-vehicle device; a step S107 where an on-vehicle device generates on-board side change data Cand wirelessly transmits it to the ground device; a step S112 where the ground device collates received on-board side change data Cwith ground side change data Cto judge whether or not to update; a step S113 where the ground device wirelessly transmits update permission to the on-vehicle device on the basis of a judgment result of the update propriety; and a step S114 where the update data Bwhich the on-vehicle device has received upon receiving the update permission is installed on the on-vehicle database.

    【課題】伝送によりデータ化けしたデータが更新データとして車上装置のデータベースにインストールされないようにする、無線による車上装置のデータベースのデータ更新方法を提供する。【解決手段】地上側更新データB1を地上装置が車上装置に無線送信するステップS104、車上装置が車上側変更データC2を生成し地上装置に無線送信するステップS107、地上装置が受信した車上側変更データC3を地上側変更データC1と照合し更新可否を判定するステップS112、地上装置が更新可否の判定結果に基づいて更新許可を車上装置に無線送信するステップS113、及び、更新許可を受信して車上装置が受信した更新データB1を車上データベースにインストールするステップS114とから成る。【選択図】図2
