Driving evaluation apparatus, driving evaluation program, and driving evaluation method

摘要

There are provided a driving evaluation method for evaluating a fuel consumption rate of driving a vehicle in certain driving interval on the basis of driving data acquired at time of driving in the driving interval, including: calculating an energy consumption efficiency in the driving interval; calculating a driving environment variable indicative of an environment factor which exerts an influence on energy consumption by driving in the driving interval; selecting a probability density function or a cumulative distribution function corresponding to the calculated driving environment variable from a plurality of probability density functions or cumulative distribution functions having the energy consumption efficiency as a probability variable; and calculating an evaluation value for evaluating a fuel consumption rate of driving in the driving interval by using the selected probability density function or the selected cumulative distribution function and the calculated energy consumption efficiency.
