INFORMATION PROCESSING DEVICE AND OPERATION CURVE GENERATION METHOD

An information processing device in an embodiment includes a storage and an operation curve generator. The storage stores therein linear data including a slope and a curve for each set of certain locations, and train data including an acceleration-deceleration characteristic. The operation curve generator sets a plurality of deceleration section candidates on the basis of information about the set of certain locations stored in the storage, obtains, for each of the deceleration section candidates, a change rate of energy consumption when the deceleration is performed by a certain speed using a preset operation curve, the linear data, and the train data, selects the section in which the change rate of energy consumption in the obtained change rates of energy consumption is the largest from the deceleration section candidates, and updates the preset operation curve utilizing the selected deceleration section and the certain speed.
