  • Patent number: 10946752
    Abstract: The number of opportunities where external charging of a vehicle parked in a residential parking space or a charging station in a predetermined period is available is counted as the number of opportunities, and the number of times of the external charging performed in the opportunities in the same predetermined period is counted as the number of times of charging. The number of times of charging is then divided by the number of opportunities to calculate and store a charging frequency. Since the charging frequency is a ratio of the number of times that the external charging was performed to the number of opportunities where the external charging is available in the predetermined period, the ratio is used as an index that can offer more accurate determination regarding an external charging utilization status. As a result, various processing to promote external charging are executed more properly.

    Abstract: An object is to provide advertisements using a plurality of vehicles with enhanced effectiveness. An information processing apparatus obtains information relating to the speed of a plurality of vehicles passing through a specific area. If a first vehicle leaves the specific area before completing display of an advertisement, the information processing apparatus causes a second vehicle that enters the specific area later than the first vehicle to display the advertisement upon entering the specific area in such a way as to start the display of the advertisement from the point in the advertisement displayed by the display apparatus of the first vehicle at the time of its leaving of the specific area. The aforementioned point in the advertisement is determined based on the speed information.
