And a transmission unit 112 for notifying the center 200 of the situation of an emergency when the control unit 111 determines that there is an emergency.

The center 200 is equipped with the in-vehicle terminal 100.
The receiving unit 201 that receives information from the emergency notification
And a storage unit 202 that stores map information, route information, and the like.
When the receiving unit 201 receives the information indicating the emergency, the display unit 2 that displays the information indicating the emergency
03, a transmission unit 204 for notifying a mobile phone of another person near the vehicle where the emergency has occurred and the like, and a control unit 205 for controlling them.

Next, the operation of the emergency call device according to the embodiment of the present invention and the emergency call system using this emergency call device will be described in detail.

First, the emergency notification device according to the embodiment of the present invention is turned on to turn on the GPS receiving unit 1.
01, the azimuth sensor 102, and the speed sensor 103 operate, respectively, and the current position measuring unit 104 measures the current position of the vehicle. Positioning of the current position is continuously performed repeatedly at regular time intervals after the power is turned on, and the current position measured is controlled by the control unit 111 and the display unit 110 together with the map information stored in the storage unit 109. Is displayed in.

When a destination is input using the input unit 108 and a predetermined search command operation is performed, the control unit 106 uses the map information stored in the storage unit 109 to determine the route from the current position to the destination. The search is performed and the route is stored in the storage unit 105.
And the map information is displayed on the display unit 110. Therefore, in this state, if the vehicle travels toward the destination along the optimum route displayed on the display unit 110, when the vehicle arrives at a predetermined guide point (main building, intersection, etc.), The guide information of the guide point is displayed by voice or on the display unit 110, and the vehicle can be accurately guided to the destination based on this guide information.

By the way, according to the present embodiment, in addition to the destination, the waypoint can be entered. When the waypoint is entered, the destination is reached via the waypoint. The arrival route is also configured so that it can be set arbitrarily. Then, when searching for a route, by inputting the search condition of the route using the input unit 108, it is also possible to search for the optimum route of each of the shortest distance and the shortest time. .

Then, in this embodiment, the storage unit 109
If a predetermined route (arbitrary route where the user's own vehicle wants to travel) is stored, and a predetermined emergency call operation is performed in that state, the following operation is performed.

That is, if a predetermined emergency call operation is performed in a state where a predetermined route is stored in the storage unit 109, as shown in FIG.
Every time positioning is performed by 4 (step 2001), the control unit 111 determines whether or not the current position deviates from the predetermined route stored in the storage unit 109 (step 2002).

When determining whether the current position deviates from the predetermined route by the control unit 111, a predetermined distance (for example, 20 m or 50 m) from the predetermined route is previously determined.
For example, a predetermined allowable range may be set such that it is determined that the deviation does not occur even if the deviation is made, and when the deviation exceeds the allowable range, it may be determined that the deviation has occurred for the first time. In this way, since the predetermined allowable range exists, it is possible to prevent a road having a wide road width from being erroneously determined to deviate.

The allowable range can be set for each unit section of the road according to the road conditions of the preset route. It goes without saying that such a configuration is more precise and preferable. There is no such thing.

In this way, the control unit 111 judges whether or not the current position deviates from the predetermined route (step 2002). If the current position does not deviate, then the traveling speed of the vehicle is next within a prescribed range. It is determined whether it is within (step 2003). Whether or not the traveling speed of the vehicle is within a prescribed range is determined by whether or not the traveling speed of the vehicle is within a range of the average traveling speed registered in advance on a predetermined route.

That is, the section average traveling speed is set in advance for each unit section (for example, 100 m) on the predetermined route, and the average traveling speed of the vehicle measured by the vehicle speed sensor 103 is set to the section average previously set. It is judged whether it is within the specified range by whether it is slower than the traveling speed.

In this case, the upper limit section average traveling speed and the lower limit section average traveling speed which are allowed as the section average traveling speed are set respectively, and the vehicle average traveling speed is set to the upper limit section previously set. It may be configured to determine whether the vehicle traveling speed is within a prescribed range by determining whether the vehicle traveling speed is within the range between the average traveling speed and the lower-limit section average traveling speed.

According to this structure, it is possible to judge that the average traveling speed of the vehicle is higher or lower than the prescribed range, and it is judged that the average traveling speed is out of the prescribed range. Not only in the case of emergency, but also in the case of early, it will be judged that it is out of the prescribed range, and it will be possible to deal with it early in an emergency.

Here, the section average traveling speed preset for a predetermined route may be preset according to the daily traffic situation on the route, but in the present embodiment, the traffic situation which changes moment by moment. To deal with VIC
The traffic information acquisition unit 105 such as S obtains the traffic information of each predetermined route from moment to moment, and updates the section average traveling speed of each predetermined route based on the obtained traffic information. Therefore, in the present embodiment, the section average traveling speed is set accurately in real time every moment, and an abnormality such as an emergency can be detected more accurately.

It is to be noted that, here, the case where it is judged whether or not the traveling speed of the vehicle is within a prescribed range after judging whether the current position deviates from a predetermined route (step 2002) (step 2003) will be explained. However, the present invention is not limited to this step, and an emergency is determined based on whether the traveling speed of the vehicle is within a specified range without passing through the step of determining whether the current position deviates from a predetermined route. It may be configured to detect an abnormality such as a situation.

In this way, it is judged whether the traveling speed of the vehicle is outside the specified range (step 2003). If it is judged that the traveling speed is not outside the specified range, then it is determined whether the vehicle is meandering. It is judged (step 2004).
The determination as to whether the vehicle is meandering is made based on whether or not the direction of the vehicle has been changed a predetermined number of times or more within a predetermined period of time. If the vehicle is not meandering, the series of steps is ended.

When it is determined that the current position of the vehicle deviates from the predetermined route (Y in step 2002), it is determined that the traveling speed of the vehicle is outside the specified range (Y in step 2003). Alternatively, when it is determined that the vehicle is meandering (Y in step 2004), it is determined that an emergency has occurred, and the control unit 111 causes the display unit 110 or an alarm device (not shown). Is used to issue an alarm and display (step 2005). And
At the same time, the occurrence of an emergency is transmitted to the center 200 side using the transmission unit 112 (step 2006).

When the emergency situation is transmitted to the center 200 side, in addition to the information and the message that the emergency situation has occurred, the number of the vehicle registered in advance and the current position locating unit 10 are displayed.
The current position of the vehicle determined by 4 is also transmitted at the same time. Further, the control unit 111 further causes the microphone unit 106,
The camera unit 107 is put into an operating state, and the ambient sound and image obtained by the microphone unit 106 and the camera unit 107 are also stored in the storage unit 109, respectively. 200
Send to the side.

As described above, according to the emergency call device of the present embodiment, the vehicle deviates from the predetermined route set in advance, the traveling speed of the vehicle is out of the specified range,
When the vehicle meanders more than a prescribed amount, each is judged to be an emergency, and an alarm and display are given, and the emergency is notified to the center 200.

The center 200, which has received the notification, operates to quickly and accurately deal with the emergency, as will be described below. That is, in the present embodiment, when the in-vehicle terminal 100 transmits the information on the emergency described above to the center 200 side, all of this information is transmitted to the center 2.
The signal is received by the receiving unit 201 on the 00 side (step 200
7), and is supplied to the control unit 205 on the center side 200 side.

The control unit 205 on the side of the center 200 activates an alarm device (not shown) based on a message informing of an emergency and issues an alarm, and the message, vehicle number, current position, etc. are stored in the storage unit 202. It is stored and displayed on the display unit 203 (step 200
8). Then, the received audio signal is reproduced by a speaker (not shown), and the video signal is displayed on the display unit 203 (step 2008).

Therefore, it is possible to accurately recognize where and what kind of emergency situation has occurred by these alarms, displays, and reproduction outputs, and dispatch an emergency vehicle on the side of the center 200, police, or other cooperation. Can be installed immediately.

Further, according to the present embodiment, the transmission section 204 is further provided, and the transmission section 204 can transmit the message informing the emergency to the vehicle near the emergency occurrence point. (Step 20
09) Therefore, the person who receives this message has the advantage of being able to monitor the occurrence of an emergency situation to some extent, which is also very useful for the arrest of criminals.

In the present embodiment, the case where the emergency report destination is the center has been described, but the present invention is not limited to the center, and the report destinations of nearby vehicles and vehicle managers and owners are not limited to the center. You may make it transmit to a telephone etc. By doing so, the number of report destinations is expanded, and more effective response can be taken.

Although the vehicle terminal 100 is provided with the navigation function as it is in the embodiment, it may be provided with only the function of the emergency notification device. It goes without saying that the navigation function and the emergency call function may be separately configured and combined.

[0051]

As described above, according to the present invention, not only when the vehicle deviates from the preset route, but also when the traveling speed of the vehicle is not within the preset specified range,
It is determined that the situation is an emergency and the situation is automatically notified to the center, and when an emergency occurs, the vehicle often stops temporarily, remarkably slows down, or speeds up to escape. In view of the above, it is possible to provide an emergency notification device having an effect of being able to more accurately detect and report an emergency situation.
