Mobility service supporting device, mobility system, mobility service supporting method, and computer program for supporting mobility service

A mobility system comprising:

• a vehicle-mounted device installed in an autonomous driving control vehicle;
• a server connected to be communicable with the vehicle-mounted device and with a portable terminal of a user of the vehicle via a network, and
• at least one in-vehicle camera for detecting the portable terminal;
• wherein:
• the vehicle-mounted device transmits information about a current position of the vehicle to the server;
• and
• the server transmits, based on arrival information that is determined from an expected time of arrival for a destination of the user determined from the information about the current position of the vehicle which is received from the vehicle-mounted device, a preventative notification for preventing the portable terminal from being left behind in the vehicle to the portable terminal of the user before the vehicle arrives at the destination of the user, the server configured to transmit the preventative notification to the portable terminal and independent of detection of the portable terminal, said server also configured to transmit, based on the arrival information, based on the at least one in-vehicle camera detecting that the portable terminal has been left behind in the vehicle, an article-left-behind notification notifying the user that the portable terminal has been left behind in the vehicle after arrival of the vehicle at the destination of the user to a predetermined terminal that is different from the portable terminal.

A non-transitory computer readable medium for supporting a mobility service, the medium causing a computer to transmit, based on arrival information that is determined from an expected time of arrival for a destination of a user determined from information about a current position of an autonomous driving control vehicle which is received from a vehicle-mounted device installed in the vehicle via a communication unit configured to be communicable with the vehicle-mounted device and with a portable terminal of a user of the vehicle, and with at least one in-vehicle camera for detecting the portable terminal, a preventative notification to the portable terminal of the user via the communication unit for preventing the portable terminal from being left behind in the vehicle before arrival of the vehicle at the destination of the user, said computer readable medium causing the computer to transmit the preventative notification to the portable terminal of the user independent of detection of the portable terminal, said computer readable medium configured to cause the computer to transmit, based on the arrival information, based on the at least one in-vehicle camera detecting that the portable terminal has been left behind in the vehicle, an article-left-behind notification notifying the user that the portable terminal has been left behind in the vehicle after arrival of the vehicle at the destination of the user to a predetermined terminal that is different from the portable terminal.
