To make it possible to efficiently replace a replaceable battery which is provided on each of wheels of an electric vehicle.SOLUTION: A drive control device includes: a travel information reception part which receives travel information containing a weight of a baggage to be loaded on an electric vehicle having a plurality of replaceable batteries for supplying electric power to drive driving wheels that are respectively provided corresponding to the plurality of driving wheels and information indicating a travel route on which the electric vehicle loading the baggage travels; a necessary power calculation part which calculates a predicted value of electric power required in order that the electric vehicle travels on the travel route on the basis of the weight of the baggage; a residual electric power calculation part which calculates a predicted value of residual electric power of each battery in a departure place of the travel route; and an electric power information transmission part which sends electric power information containing the predicted value of necessary electric power and the predicted value of residual electric power to an emergency control device. The emergency control device includes a replacement number determination part which determines the number of batteries to be replaced for the electric vehicle in the departure place on the basis of the electric power information.SELECTED DRAWING: Figure 1 【課題】電動車両の各車輪それぞれに設けられた交換式のバッテリを効率良く交換することができるようにする。【解決手段】駆動制御装置は、駆動輪を駆動する電力を供給する複数の交換式のバッテリが複数の駆動輪のそれぞれに対応して設けられた電動車両に積載される荷物の重量と、当該荷物を積載された電動車両が走行する走行ルートを示す情報とを含む走行情報を受信する走行情報受信部と、荷物の重量に基づいて、電動車両が走行ルートを走行するために必要な電力の予測値を算出する必要電力算出部と、走行ルートの出発地点におけるバッテリの残電力の予測値を算出する残電力算出部と、必要な電力の予測値と残電力の予測値とを含む電力情報を管制制御装置に送信する電力情報送信部とを有する。管制制御装置は、電力情報に基づいて、出発地点において電動車両が交換するバッテリの個数を決定する交換数決定部を有する。【選択図】図１
