摘要：PROBLEM TO BE SOLVED: To provide an in-vehicle device that can allow a user to immediately grasp an adequate determination result about a degree of eco-driving that is at least one of states that exhausting of exhaust gas is suppressed and that consumption of energy is suppressed. SOLUTION: At a determination timing of one minute cycle after starting driving, determination of a degree of eco-driving (eco-driving determination) is made in a plurality of different observation points about a driving of an own vehicle in a time period from one minute before to a time point of the determination timing and about a driving of the own vehicle in a time period from starting of the driving to the time point of the determination timing (referred to as one trip). A navigation device respectively determines eco-driving levels about driving in one minute and driving in one trip, i.e., a total determination result about the degree of the eco-driving, on the basis of the determination results of the eco-driving determination, and then displays the eco-driving levels (S250).
