PROBLEM TO BE SOLVED: To estimate a drive operation characteristics of an individual driver in detail regarding a drive operator.SOLUTION: A vehicular drive operation characteristics estimation device 100 performs: calculating an amplitude between inflection points, which is a difference value of operation amounts corresponding to individual two inflection points that are adjacent in time series, and time between inflection points, which is a temporal interval of the individual two inflection points, on the basis of inflection points of temporal change in operation amounts of a drive operator at a set time t1; calculating an amplitude median value and a temporal median value, which are median values of the aforementioned amplitude and time; transmitting a request for obtaining information for estimation, the information containing operation characteristic information that is a set of the aforementioned amplitude median value and temporal median value, to a characteristic information managing server 200, which then transmits information for estimation that includes information of a relative position between a centroid value of a set of information of operation characteristic information of the individual of a number of anonymous drivers and the operation characteristic information contained in the request for obtaining, to the device 100; and estimating a drive operation characteristics of an individual driver of an automobile 1 regarding the drive operator on the basis of the received information for estimation. |
