2. Description of the Related Art A vehicle emergency information system is a system for automatically reporting vehicle emergency information to an emergency service center via a wireless line from a vehicle emergency information reporting device mounted on a vehicle when an accident such as a vehicle collision occurs. is there. The automatic notification in the event of an accident is to automatically notify the emergency service center in the event of a vehicle collision or accident, and then to the public assistance organization.

With this system, the time required for an emergency vehicle such as an ambulance or police car to arrive at the site can be shortened, and the injured person can be rescued and rescued more quickly. Also,
Even in the event of an emergency such as the occurrence of a sudden illness, by pressing the emergency button on the vehicle emergency information reporting device, the vehicle emergency information is reported to the emergency service center via a wireless line, and a conversation with the service personnel at the emergency service center can be made. It can be carried out.

A conventional vehicle emergency information system is disclosed, for example, in Japanese Patent Application Laid-Open No. 6-251292. The system disclosed in this publication, as shown in FIG. 2, uses a vehicle-mounted telephone to automatically report information at the time of a vehicle collision to an emergency service center. The signal processing unit monitors signals from the airbag deployment device and the like, and when an accident such as a collision is detected, automatically transmits the accident situation data of the vehicle to the center by a wireless device via a modem. When the data transmission is completed, the changeover switch is switched to the receiver so that a voice call can be made between the vehicle occupant and the center personnel.

[0005]

In the conventional system, when an emergency button is pressed to make an emergency call, the probability of establishing communication even when the emergency button is pressed in a place where the electric field of the cellular phone network is weak is low. Few.

[0006] When handling an accident, it is necessary to grasp the number of passengers and take appropriate measures.

Further, when a nonlife insurance company handles an accident, it is required to quickly and accurately grasp the accident situation and determine the contents of compensation.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide an in-vehicle apparatus for an emergency call system in which the probability of establishing communication is improved.

Another object of the present invention is to provide an in-vehicle device of an emergency notification system capable of ascertaining the number of passengers in an accident vehicle at a center.

A further object of the present invention is to provide an emergency notification system that enables a nonlife insurance company to quickly and accurately grasp the status of an accident.

[0011]

An on-vehicle apparatus of an emergency notification system according to the present invention includes means for detecting electric field strength, and display means for visually displaying the detected electric field strength. With this configuration, the electric field intensity can be detected and a visual display can be performed.

[0012] The on-vehicle device of the emergency notification system according to the present invention comprises an occupant number detecting means for detecting the number of occupants of a vehicle equipped with the on-vehicle device, and a transmitting means for transmitting the occupant number to a center when an emergency occurs. And with. With this configuration,
When an emergency occurs, the number of occupants of the vehicle can be transmitted from the vehicle-mounted device to the center.

Further, the emergency notification system according to the present invention is characterized in that a storage means in which identification information of a non-life insurance company with which the owner of the vehicle equipped with the on-vehicle device is contracted is stored in advance; An in-vehicle device including a transmitting unit that transmits information to a center, a storage unit in which identification information of a non-life insurance company under contract with an owner of a vehicle equipped with the in-vehicle device is stored in advance, and And a transmitting unit for notifying the property / casualty insurance company identified by the identification information of the information on the accident situation when receiving the information on the accident situation together with the identification information. With this configuration, when an emergency occurs, the accident situation and the identification number of the non-life insurance company are transmitted from the vehicle-mounted device to the center, and the center can notify the non-life insurance company specified by the identification number of the accident situation.
