Vehicle and terminal device location determining system, and method

A non-transitory computer readable storage medium storing computer executable instructions that causes a server, which is configured to communicate with a vehicle and a terminal device, to perform processes comprising:

• repeatedly receiving, from the vehicle, positional information on the vehicle at predetermined timings;
• repeatedly receiving, from the terminal device, user identification information that identifies a user of the terminal device and positional information on the terminal device at predetermined timings, and the predetermined timings of transmitting the positional information of the terminal device is set to be when the terminal device is detected to accelerate or decelerate;
• and
• determining whether the terminal device entered into a reference region, which is set to be within a predetermined threshold distance from the vehicle, the predetermined threshold distance being a threshold set to determine whether the user was located in the vehicle, and the predetermined threshold distance is based on the positional information on the terminal device and the positional information on the vehicle.

An information processing method that is carried out by an information processing system including a vehicle, a terminal device, and a server configured to communicate with the vehicle and the terminal device, the method comprising:

• repeatedly transmitting, by the vehicle, positional information on the vehicle to the server at predetermined timings;
• repeatedly transmitting, by the terminal device, user identification information that identifies a user of the terminal device and positional information on the terminal device to the server at predetermined timings, and the predetermined timings of transmitting the positional information of the terminal device is set to be when the terminal device is detected to accelerate or decelerate;
• and
• determining, by the server, whether the terminal device enters into a reference region, which is set to be within a predetermined threshold distance from the vehicle, the predetermined threshold distance being a threshold set to determine whether the user is located in the vehicle, the predetermined threshold distance being based on the positional information on the terminal device and the positional information on the vehicle.
