2. Description of the Related Art In a traffic accident or the like, the time from the occurrence of an accident until the first treatment is closely related to the survival rate. Therefore, as shown in FIG. 1, when an accident such as a vehicle collision occurs, an emergency notification device mounted on the accident vehicle 1 automatically notifies the emergency center 2 of the vehicle emergency information, and the emergency vehicle 4
A vehicle emergency notification system has been proposed that aims to reduce the number of fatalities and severely disabled people by shortening the time it takes to arrive at the accident site so that injured people can be rescued and rescued more quickly. I have. In such a vehicle emergency notification system, a technology for acquiring and displaying information for grasping an accident situation such as a vehicle speed immediately before the accident and an accident cause in addition to a site position at the time of the accident is indispensable.

An emergency notification device mounted on a vehicle usually has the following functions. (1) Communication function: Has a communication function similar to that of a mobile phone, and enables automatic switching between data communication and voice communication. (2) Position detection function: Records vehicle position data such as GPS, vehicle speed sensor, and gyro as data for vehicle position detection. (3) Emergency detection function: It has a collision position detection sensor and a rollover sensor and detects what kind of accident has occurred. (4) Vehicle emergency call function: An emergency call is started by detecting a collision position detection sensor or a rollover sensor, and the recorded vehicle position data is automatically transmitted. Manual notification by pressing the vehicle emergency information notification button is also enabled.

FIG. 2 shows a schematic configuration of an emergency notification device having such a configuration. In FIG. 2, an emergency notification device 5 mounted on the accident vehicle (see FIG. 1) is connected to a GPS antenna 9 to receive data from a GPS satellite.
It includes an S receiving unit 8, a gyro 10, a vehicle speed pulse detecting unit (vehicle speed sensor) 11, a collision detecting unit (collision sensor) 12, and a public cellular phone (wireless device) 6, and further includes a control unit 7 for controlling these. It is configured.

[0005] In the emergency notification device 5, in addition to the calculation of the vehicle position by the GPS receiving unit 8 and the gyro 10, the vehicle speed information by the vehicle speed pulse detecting unit (vehicle speed sensor) 11 is transmitted every time the vehicle speed changes or every fixed time. The data is stored in a storage unit (not shown) by the control unit 7. When the collision detection unit (collision sensor) 12 operates when an accident occurs, the site location information and the vehicle speed information accumulated from the public cellular phone (wireless device) 6 are transmitted to the emergency center (see FIG. 1) by data communication. I do.

Has the configuration shown in FIG. When an accident occurs, the emergency notification device 5 transmits site position information and vehicle speed information to the emergency center by data communication. Then, the communication device 13
Receives, by data communication, site position (latitude and longitude) information and vehicle speed information when an accident occurs. In addition, the map matching device 14 performs map matching based on the received site position (latitude / longitude) information. The object search device 15
The object is searched from the site position (latitude / longitude) information from the map matching device 14 and the map database 17. The emergency information display device 16 receives the advanced latitude / longitude (site position) information and vehicle speed information obtained through the map matching device 14, the target information obtained from the target search device 15, and the map database 17. Emergency information is displayed based on the obtained map data. Then, the operator located on the emergency information display device 16 reads the displayed emergency information and requests the rescue organization 3 for rescue via the public network.

It has been proposed to provide a navigation device for displaying the running position of a vehicle with a position reporting function at the time of occurrence of an accident, similarly to the emergency notification device. For example, Japanese Patent Laying-Open No. 5-5626 discloses a navigation device of this type.

This device includes a location device for determining the position of the host vehicle of the vehicle, an acceleration sensor as an accident occurrence detecting means, a control device for storing the own vehicle position data obtained by the location device and outputting it when an accident occurs, A communication device as data transmission means, the location device includes a direction sensor for detecting a traveling direction of the vehicle, a distance sensor for detecting a traveling distance of the vehicle, and an absolute position determination sensor for receiving GPS data. , A CDROM in which map data and telephone numbers of contacts are stored, and a CPU for obtaining a vehicle position from information of each sensor and displaying it on a display device.

FIG. 4 shows a conventional emergency information display device.
Operation 16 will be described. When the vehicle encounters an accident, the vehicle position data recorded in the emergency notification device 5 of the accident vehicle is automatically transmitted to the emergency center.
The vehicle position data described above is received via 13 and map matching is performed by a map matching device 14 based on this data, and furthermore, on-site position display processing is performed based on the map data in the map database 17 to confirm the position of the accident vehicle. And request that an emergency vehicle be dispatched.

[0010]

In the emergency call system, information such as the position of the site and the running locus at the time of the accident can be displayed by data communication from the on-board unit.
There is a problem that information for grasping an accident situation such as a vehicle speed immediately before the accident and an accident cause cannot be displayed on the center device (operator).

According to the present invention, a vehicle-mounted device (emergency notification device) has means for transmitting vehicle speed information, and a center device having received the vehicle speed information displays a running locus mark which is color-coded in several stages according to the vehicle speed information. It is an object of the present invention to provide a method and apparatus for displaying emergency information that enables a center apparatus operator to grasp the vehicle speed immediately before an accident and to enable conversation with an appropriate party by displaying the information on a map.

(Emergency notification device), and in addition to calculating the vehicle position, accumulates vehicle speed information every time the vehicle speed changes or every fixed time, and transmits data on site and vehicle speed information when an accident occurs. Means for transmitting to the emergency center.

[0013] The emergency center is provided with means for displaying the received spot position and the traveling locus on a map so as to be superimposed on the map. When displaying the traveling locus, the traveling center is color-coded in several stages according to the vehicle speed information. A means for superimposing and displaying the locus mark on the map is provided.

[0014] With this configuration, the center device operator can expect that if the vehicle speed is high immediately before the accident, the influence on the accident vehicle and the persons concerned will be large. Accordingly, it is possible to perform an appropriate emergency rescue operation even when the conversation from the accident vehicle is silent.
