<p><P>PROBLEM TO BE SOLVED: To provide an emergency reporting device reduced in the load on the communication line of a base station at the time of transmitting an emergency signal. <P>SOLUTION: This emergency reporting device 1 counts the time after leaving the communication area of a base station until detecting a peripheral vehicle and stores it in a traveling time storing part 22, and the peripheral vehicle also counts the time in the same way. When its own vehicle encounters with the peripheral vehicle after receiving an emergency signal from an emergency vehicle, the transfer of the traveling time information is carried out between those two vehicles. The emergency reporting device 1 decides whether or not to transmit the emergency signal owned by its own vehicle to the peripheral vehicle based on the traveling time information transferred at the time of encountering with the peripheral vehicle. <P>COPYRIGHT: (C)2004,JPO</p> |
