Abstract
To provide an operation start index value calculating unit for calculating index values of operation start times according to operation contents of a driver who drives a vehicle, and a driving characteristics estimating unit for determining ratios of probability densities to total value thereof in respective probability density functions in the calculated index values, based on the respective probability density functions of every state of the operation start times to the index values of the operation start times and on the index values of the operation start times calculated by the operation start index value calculating unit, and for estimating the driving characteristics of the driver by weighting the ratios to the total values of the respective probability densities.
