Zusammenfassung:PROBLEM TO BE SOLVED: To provide a technique that reduces the time to write data.SOLUTION: A CPU 12 determines, in S10, whether there is a setting request that indicates a request for setting a set value that indicates settings to the electronic controller to a designated value that is one of a plurality of candidates for the set value. In S50, when there is a setting request, the CPU 12 acquires a match address that is an address indicating an area where a candidate value that matches the designated value among the plurality of candidate values is stored. In S90, the CPU 12 causes data that represents the match address to be written to a storage area for the set value that is a storage area previously allocated to the set value by a controller 15 that performs a write of data for each of predetermined storage unit areas.SELECTED DRAWING: Figure 5 【課題】データの書込時間を短縮する技術を提供する。【解決手段】CPU12は、S10では、当該電子制御装置に対する設定を表す設定値を設定値に対する複数の候補値のうちの一つである指定値に設定する要求を表す設定要求、が有るか否か判断する。S50では、設定要求が有る場合に、複数の候補値のうち指定値と一致する候補値が記憶されている領域を示すアドレスである一致アドレス、を取得する。S90では、設定値に対して予め割り当てられた記憶領域である設定値用記憶領域に、一致アドレスを表すデータを、予め定められた記憶単位領域毎にデータの書込を行うコントローラ15に書き込ませる。【選択図】図5
