Safety information transmission method and safety information transmission system

A safety information transmission method in a safety information transmission system constituted by a portable terminal and a plurality of vehicle-mounted terminals, comprising:

• receiving a disaster occurrence notification at a first vehicle-mounted terminal;
• distributing a disaster application program from the first vehicle-mounted terminal to a first portable terminal in response to reception of the disaster occurrence notification;
• installing the disaster application program in the first portable terminal;
• transmitting a terminal ID from the first portable terminal to the first vehicle-mounted terminal using the disaster application program;
• storing as safety information in the first vehicle-mounted terminal, the terminal ID received from the first portable terminal in association with position information and time information acquired by the first vehicle-mounted terminal;
• transmitting the safety information from the first vehicle-mounted terminal to a second vehicle-mounted terminal by a vehicle-to-vehicle communication;
• storing, in the first vehicle-mounted terminal, safety information received from the second vehicle-mounted terminal by the vehicle-to-vehicle communication;
• and
• transmitting, from the first or second vehicle-mounted terminal, safety information stored therein to an information server via an access point in a case where the first or second vehicle-mounted terminal has reached a communication possible area of the access point, or transmitting the safety information stored therein to a second portable terminal in a case where the first or second vehicle-mounted terminal has become capable of communicating with the second portable terminal.

A safety information transmission system, comprising:

• a first portable terminal having:
• a portable storage that stores safety information;
• a portable communicator;
• and
• a portable processor configured to:
• receive a disaster application program via the portable communicator;
• install the disaster application program in the portable storage;
• and
• transmit the safety information via the portable communicator using the disaster application program;
• and
• a first vehicle-mounted terminal having:
• a vehicle-mounted communicator;
• a vehicle-mounted storage;
• and
• a vehicle-mounted processor configured to:
• receive a disaster occurrence notification;
• distribute the disaster application program to the first portable terminal via the vehicle-mounted communicator in response to reception of the disaster occurrence notification;
• receive the safety information from the first portable terminal via the vehicle-mounted communicator;
• store the received safety information in the vehicle-mounted storage;
• transmit the stored safety information to a second vehicle-mounted terminal via the vehicle-mounted communicator by a vehicle-to-vehicle transmission;
• and
• transmit the stored safety information to an information server via the vehicle-mounted communicator and an access point in a case where the first vehicle-mounted terminal has reached a communication possible area of the access point, or transmit the stored safety information to a second portable terminal via the vehicle-mounted communicator in a case where the first vehicle-mounted terminal has become capable of communicating with the second portable terminal.

• a vehicle-mounted communicator;
• a vehicle-mounted storage;
• and
• a vehicle-mounted processor configured to:
• receive a disaster occurrence notification;
• distribute the disaster application program to the first portable terminal via the vehicle-mounted communicator in response to reception of the disaster occurrence notification;
• receive the terminal ID transmitted by the first portable terminal via the vehicle-mounted communicator;
• acquire position information;
• acquire time information;
• store as safety information the received terminal ID in association with the acquired position information and the acquired time information;
• transmit the stored safety information to a second vehicle-mounted terminal via the vehicle-mounted communicator by a vehicle-to-vehicle transmission;
• and
• transmit the stored safety information to an information server via the vehicle-mounted communicator and an access point in a case where the first vehicle-mounted terminal has reached a communication possible area of the access point, or transmit the stored safety information to a second portable terminal via the vehicle-mounted communicator in a case where the first vehicle-mounted terminal has become capable of communicating with the second portable terminal.
