To provide a train drive efficiency estimation device generating an efficiency map when a train travels: and to provide a train drive efficiency estimation method.SOLUTION: A train drive efficiency estimation device includes a storage part, a drive efficiency estimation part and an efficiency map generation part. The storage part stores information on at least power consumption and the velocity of the train of the power consumption of the train as an object for generating the efficiency map, the velocity, the weight, the acceleration and a tension command value, on a plurality of time-lapse cross sections. The drive efficiency estimation part estimates efficiency indicating a ratio for converting the power consumption of the train to the tensional power of the train according to the velocity of the train using information on the plurality of time-lapse cross sections stored in the storage part. The efficiency map generation part generates an efficiency map indicating a relation between the velocity of the train, the tensional force of the train and the efficiency.SELECTED DRAWING: Figure 1

    【課題】列車の走行時における効率マップを生成可能な列車駆動効率推定装置および列車駆動効率推定装置方法を提供する。【解決手段】本実施形態に係る列車駆動効率推定装置は、記憶部と、駆動効率推定部と、効率マップ生成部とを備える。記憶部は、効率マップを生成する対象となる列車の消費電力、速度、重量、加速度、及び引張力指令値の内の少なくとも列車の消費電力、及び速度の情報を複数の時断面において記憶する。駆動効率推定部は、記憶部に記憶される複数の時断面の情報を用いて、列車の消費電力を列車の引張力に変換する割合を示す効率を列車の速度に応じて推定する。効率マップ生成部は、列車の速度と、列車の引張力と、効率との関係を示す効率マップを生成する。【選択図】図1
