Information processing device, information processing method, and program

Abstract

This invention provides a better information processing device, information processing method, and program for estimating vehicle deterioration indicators. [Solution] The information processing device 10 includes an observation data acquisition unit 24 that acquires observation data of a deterioration index, which is an indicator related to the deterioration of a vehicle, and a pre-estimated data determination unit 30 that can determine pre-estimated data used in data assimilation processing for estimating the deterioration index by selecting from a plurality of pre-prepared pre-estimated data candidates based on the observation data.

Claims

[Claim 1] An observation data acquisition unit that acquires observation data of deterioration indicators, which are indicators related to the deterioration of vehicles, A pre-estimate data determination unit that can determine the pre-estimate data used in the data assimilation process for estimating the aforementioned degradation index by selecting from a plurality of pre-prepared pre-estimate data candidates based on the observed data, An information processing device equipped with the following features. [Claim 2] An information processing apparatus according to claim 1, The information processing device includes a pre-estimation data determination unit that selects a candidate for the pre-estimation data that has the smallest degree of deviation from the observed data as the pre-estimation data. [Claim 3] An information processing apparatus according to claim 2, If the degree of discrepancy between the first pre-estimated data candidate and the observed data is less than a predetermined degree, the pre-estimated data determination unit determines the first pre-estimated data candidate as the pre-estimated data. If the degree of discrepancy between the first pre-estimated data candidate and the observed data is greater than or equal to a predetermined degree, the pre-estimated data determination unit acquires the pre-estimated data by correcting the first pre-estimated data candidate based on the observed data, in the information processing device. [Claim 4] An information processing apparatus according to any one of claims 1 to 3, An information processing apparatus further comprising a data assimilation processing unit that derives post-hoc estimated data of the degradation index by performing the data assimilation processing based on the pre-hoc estimated data and the observed data. [Claim 5] An information processing apparatus according to any one of claims 1 to 3, The aforementioned pre-estimated data candidates are prepared to correspond to multiple user classifications whose vehicle usage patterns differ from one another, and are provided in an information processing device. [Claim 6] An information processing device according to claim 5, It further comprises a pre-estimated data candidate generation unit that generates multiple pre-estimated data candidates, The aforementioned pre-estimated data candidate generation unit is an information processing device that generates pre-estimated data candidates corresponding to the usage patterns of each of the plurality of user classifications by estimation using an estimation model. [Claim 7] An information processing device according to claim 5, An information processing device further comprising a user classification setting unit that sets multiple user classifications based on traceability data obtained from multiple monitoring vehicles. [Claim 8] An information processing apparatus according to claim 7, The monitoring vehicle is a fuel cell vehicle equipped with a fuel cell, An information processing device wherein the traceability data obtained from the monitoring vehicle is data relating to at least one of the following: the output current of the fuel cell, the operating pressure of the fuel cell, the hydrogen flow rate of the fuel cell, the air flow rate of the fuel cell, the voltage of the fuel cell, the temperature of the fuel cell, and the humidity of the fuel cell. [Claim 9] An observation data acquisition step to obtain observation data of deterioration indicators, which are indicators related to vehicle deterioration, A pre-estimate data determination step in which pre-estimate data used in data assimilation processing for estimating the aforementioned degradation index can be determined by selecting from a plurality of pre-prepared pre-estimate data candidates based on the observed data, An information processing method having the following characteristics. [Claim 10] A program for causing a computer to execute the information processing method described in claim 9.
