Patent ID: 7904235

Claim:
A driving evaluation method for evaluating a result of driving a vehicle in certain driving interval on the basis of driving data acquired at time of driving in the driving interval, comprising: calculating an energy consumption efficiency in the driving interval, by using the driving data; calculating a driving environment variable indicative of an environment factor which exerts an influence on energy consumption by driving in the driving interval, on the basis of the driving data; 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 result 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, wherein the calculating an energy consumption efficiency includes calculating energy consumption amount in the driving interval, travel distance in the driving interval, and racing energy consumption amount as energy amount consumed by racing in the driving interval, and calculating, as the energy consumption efficiency, no-racing energy consumption rate which is expected energy consumption rate in the case where no racing is performed, on the basis of no-racing energy consumption amount as difference between the energy consumption amount and the racing energy consumption amount and the travel distance.
