Emergency notification system and method for notifying emergency
First Claim
1. An emergency notification system comprising:
- an in-vehicle emergency notification device mounted on a vehicle; and
a center device mounted in a service center,wherein the in-vehicle emergency notification device transmits a preliminary notification signal to the center device via a communication network when the in-vehicle emergency notification device determines that a possibility to collide on another vehicle or an obstacle is equal to or higher than a predetermined threshold value,wherein the in-vehicle emergency notification device transmits an emergency notification signal to the center device via the communication network when the in-vehicle emergency notification device determines that the vehicle collides on another vehicle or an obstacle,wherein the in-vehicle emergency notification device transmits a cancel signal to the center device via the communication network when the in-vehicle emergency notification device determines that the vehicle avoids collision after the in-vehicle emergency notification device determines that the possibility to collide on the another vehicle or the obstacle is equal to or higher than the predetermined threshold value,wherein the center device executes a preliminary notification process in such a manner that the center device waits for receiving the emergency notification signal or the cancel signal for a first predetermined time when the center device determines that the center device receives the preliminary notification signal from the in-vehicle emergencynotification device,wherein the center device executes an emergency notification process for notifying emergency when, the center device determines that the center device receives the emergency notification signal from the in-vehicle emergency notification device,wherein the center device terminates the preliminary notification process when the center device determines that the center device receives the cancel signal from the in-vehicle emergency notification device,wherein the center device determines whether it is necessary to execute the emergency notification process when the center device determines that the first predetermined time has elapsed without receiving the emergency notification signal and the cancel signal after the center device determines that the center device receives the preliminary notification signal from the in-vehicle emergency notification device,wherein the center device executes the emergency notification process when the center device determines that it is necessary to execute the emergency notification process, andwherein the center device terminates the preliminary notification process When the center device determines that it is not necessary to execute the emergency notification process.

Abstract
An emergency notification system includes: an in-vehicle emergency notification device; and a center device in a service center. The in-vehicle device transmits a preliminary notification signal to the center device when a possibility of collision exists, transmits an emergency notification signal when the vehicle collides, and transmits a cancel signal when the vehicle avoids collision. The center device executes a preliminary notification process for waiting the signals when receiving the preliminary notification signal, executes an emergency notification process when receiving the emergency notification signal, and terminates the preliminary notification process when receiving the cancel signal. The center device determines whether the emergency notification process is necessary when the predetermined time has elapsed without receiving the signals after receiving the preliminary notification signal, executes the emergency notification process when the emergency notification process is necessary, and terminates the preliminary notification process when the emergency notification process is not necessary.

8. A method for notifying emergency from an in-vehicle emergency notification device mounted on a vehicle to a center device mounted in a service center, the method comprising:
-
transmitting a preliminary notification signal from the in-vehicle emergency notification device to the center device via a communication network when the in-vehicle emergency notification device determines that a possibility to collide on another vehicle or an obstacle is equal to or higher than a predetermined threshold value; transmitting an emergency notification signal from the in-vehicle emergency notification device transmits to the center device via the communication network when the in-vehicle emergency notification device determines that the vehicle collides on another vehicle or an obstacle; transmitting a cancel signal from the in-vehicle emergency notification device to the center device via the communication network when the in-vehicle emergency notification device determines that the vehicle avoids collision after the in-vehicle emergency notification device determines that the possibility to collide on the another vehicle or the obstacle is equal to or higher than the predetermined threshold value; executing a preliminary notification process in the center device when the center device determines that the center device receives the preliminary notification signal from the in-vehicle emergency notification device, wherein the preliminary notification process includes waiting for receiving the emergency notification signal or the cancel signal by the center device for a first predetermined time; executing an emergency notification process in the center device for notifying emergency when the center device determines that the center device receives the emergency notification signal from the in-vehicle emergency notification device; terminating the preliminary notification process in the center device when the center device determines that the center device receives the cancel signal from the in-vehicle emergency notification device; determining by the center device whether it is necessary to execute the emergency notification process when the center device determines that the first predetermined time has elapsed without receiving the emergency notification signal and the cancel signal after the center device determines that the center device receives the preliminary notification signal from the in-vehicle emergency notification device; executing the emergency notification process in the center device when the center device determines that it is necessary to execute the emergency notification process, and terminating the preliminary notification process in the center device when the center device determines that it is not necessary to execute the emergency notification process. - View Dependent Claims (9, 10, 11, 12, 13, 14)
