Emergency reporting device
First Claim
1. An emergency reporting device to be installed in a vehicle, comprising:
- a base station communication section configured and arranged to communicate with one of a plurality of base stations and send an emergency signal to the one of the base stations after entering a communication area of the one of the base stations with the emergency signal;
a vehicle communication section configured and arranged to communicate with a peripheral vehicle to receive travel information of the peripheral vehicle; and
an emergency signal control unit including a travel information acquisition section configured to acquire travel information of the vehicle, a peripheral vehicle detection section configured to detect the peripheral vehicle equipped with the emergency reporting device in a peripheral area of the vehicle, and a transmission determination section configured to determine whether or not to send the emergency signal to the peripheral vehicle based on a comparison of the travel information of the vehicle and the travel information of the peripheral vehicle, the vehicle communication section being further configured and arranged to send the emergency signal to the peripheral vehicle based on a determination result of the transmission determination section.

Abstract
An emergency reporting device is configured to reduce the load of communication circuits of base stations when sending emergency signals. The emergency reporting device is configured to track the time in the travel time recording section from when a vehicle last exited a communication area of a base station until it detects a peripheral vehicle or track the time in the same manner for a peripheral vehicle as well. When the vehicle encounters a peripheral vehicle after receiving an emergency signal from an emergency vehicle, an exchange of travel information occurs between the two vehicles. The emergency reporting device determines whether or not to send the emergency signal held by the vehicle to the peripheral vehicle based on the travel information that was exchanged when the vehicles encountered each other.

16. An emergency reporting device installed in a vehicle for sending an emergency signal to one of a plurality of base stations comprising:
-
a roadmap storage section configured to store roadmap information, a communication area information storage section configured to store information on a plurality of communication areas of the base stations;
a vehicle position detection section configured and arranged to detect a position of the vehicle; and
a guide route setting section configured to set a guide route from the position of the vehicle to a destination of the vehicle based on the roadmap information stored in the roadmap storage section, the guide route setting section being further configured to reset the guide route such that the vehicle passes within one of the communication areas of the base stations when the vehicle receives the emergency signal based on the information on the communication areas stored in the communication area information storage section.

17. A method of selectively sending an emergency signal from a vehicle, comprising:
-
selectively sending an emergency signal to one of a plurality of base stations after entering a communication area of the one of the base stations with the emergency signal;
detecting a peripheral vehicle equipped with an emergency reporting device in a peripheral area of the vehicle;
acquiring travel information of the vehicle and the peripheral vehicle;
determining whether or not to send the emergency signal to the peripheral vehicle based on a comparison of the travel information of the vehicle and the travel information of the peripheral vehicle; and
selectively sending the emergency signal to the peripheral vehicle based on a determination result based on the comparison of the travel information of the vehicle and the travel information of the peripheral vehicle.

18. An emergency reporting device to be installed in a vehicle comprising:
-
base station communicating means for communicating with one of a plurality of base stations and sending an emergency signal to the one of the base stations after entering a communication area of the one of the base stations with the emergency signal;
peripheral vehicle detecting means for detecting a peripheral vehicle equipped with the emergency reporting device in a peripheral area of the vehicle;
travel information acquiring means for acquiring travel information of the vehicle and the peripheral vehicle;
transmission determination means for determining whether or not to send the emergency signal to the peripheral vehicle based on a comparison of the travel information of the vehicle and the travel information of the peripheral vehicle; and
vehicle communication means for sending the emergency signal to the peripheral vehicle based on a determination result of the transmission determination means.
