Abstract: A driving ability determination system, includes: an acquisition unit configured to acquire travel data of a vehicle; a first calculation unit configured to calculate a first evaluation value indicating characteristics of steering by a driver of the vehicle based on the travel data acquired by the acquisition unit; and a second calculation unit configured to calculate a second evaluation value indicating characteristics of steering by the driver of the vehicle based on travel data in a first section among pieces of the travel data acquired by the acquisition unit. The first calculation unit calculates the first evaluation value based on the travel data in the first section and travel data in a second section different from the first section among pieces of the travel data acquired by the acquisition unit.

Abstract: A driving ability determination system, includes: a processor and a memory coupled to the processor. The processor is configured to perform: acquiring time-series travel data of a vehicle; identifying a driver of the vehicle; and calculating an evaluation value indicating steering characteristics of the identified driver based on travel data during one cycle from a start time point to an end time point of the vehicle from among the acquired travel data.
