Abstract

An eco-driving probability density estimation unit and an eco-driving awareness pre-learning unit resets an evaluation standard of driving of a driver of a host vehicle for each condition in which the host vehicle is driven for each driving evaluation. Therefore, it becomes possible to set the evaluation standard of the driving in accordance with an actual condition during evaluation compared to a case where the standard for uniformly evaluating the driving is set. An eco-driving capability/proficiency estimation unit and an eco-driving awareness estimation unit evaluate the driving of the driver of the host vehicle by the evaluation standard reset by the eco-driving probability density estimation unit and the eco-driving awareness pre-learning unit. Therefore, it becomes possible to perform driving evaluation more suitable for the actual condition.
