Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle accident automatic notification device and an automatic accident notification system for promptly and automatically reporting the occurrence of an accident when a vehicle is traveling. .

[0002]

2. Description of the Related Art Conventionally, when an accident occurs while a vehicle is running, a person involved in the accident or a witness reports to a police station or a fire station by, for example, a public telephone, an emergency telephone (for example, installed on a highway), an automobile telephone or a mobile telephone. It is common to do. However, when making a call using a public telephone or an emergency telephone, it is necessary to move from inside the vehicle or from the place where the sighting is made to the place where the telephone is installed, and there is a problem that it takes some time before the call is made. On the other hand, an automobile phone or a mobile phone can make a call immediately from that location, so it does not take much time to travel, but it is not always possible to make a call when an accident occurs.

If there is no witness, the person involved in the accident must make a report, but the person involved in the accident is often injured although the degree is different. Therefore, it often takes longer to make a call than when there are witnesses. In particular, when the person involved in the accident is seriously injured, it may not even be possible to make a report, which makes the detection of the accident extremely slow. Therefore, problems related to accidents such as delay of rescue of injured people, delay of reporting to police, occurrence of secondary disasters such as rear-end collisions caused by other vehicles that are unaware of accidents (hereinafter referred to as "defects due to accidents""
That is) may occur.

Therefore, in order to report an accident as quickly as possible, an automatic accident notification system (hereinafter referred to as "the automatic safety notification system (ASV: Advanced Safety Vehicle) Promotion Study Group" composed of the Ministry of Transport and private companies etc. "ASV system") is under consideration. More specifically, the ASV system includes a collision sensor that detects whether or not a collision accident has occurred in the vehicle, a vehicle position sensor that detects the current position of the vehicle, a switch that allows the driver to input his / her injury state, and the like. In-vehicle accident notification device including an input device and a communication device, an operation center, and an emergency contact facility including a police station and a fire station.

In the above-mentioned ASV system, when a collision sensor detects that a collision accident has occurred, the occurrence of the collision accident, the current position of the vehicle detected by the vehicle position sensor, and whether the driver has pressed the switch by himself or not. Accident information including is transmitted wirelessly from the communication device to the operation center. Upon receipt of the accident information, the operation center contacts the emergency contact facility and requests the dispatch of police or ambulances. Further, at the operation center, the accident information is transmitted to the communication device provided in another vehicle.

[0006]

By the way, the above ASV
In order to realize the system, it is necessary to install an in-vehicle accident notification device in a vehicle from the manufacturing stage. This is because the collision sensor and the vehicle position sensor, in particular, need to be mounted and wired inside the outer frame of the vehicle, and therefore the retrofitting work to the completed vehicle is very complicated.

However, it is very difficult to obligate a vehicle manufacturer to install the on-vehicle accident automatic notification device in all vehicles. On the other hand, even if the driver is urged to install the in-vehicle accident automatic notification device as an option, the driver incurs an economical burden such as a purchase cost and an installation cost (because the installation is difficult). Therefore, it is expected that it will take time for the in-vehicle accident automatic notification device to spread. Therefore, a state where a vehicle equipped with the vehicle accident notification device (hereinafter referred to as “equipped vehicle”) and a vehicle not equipped with the vehicle-mounted accident notification device (hereinafter referred to as “non-equipped vehicle”) are mixed on the road continues.

In this state, if an unmounted vehicle causes an accident, the accident can only be reported by telephone as before. Therefore, there is a possibility that a malfunction may occur due to the accident. Therefore, the object of the present invention is to solve the above-mentioned technical problems and to be easily mounted on a vehicle.
It is an object of the present invention to provide an in-vehicle accident automatic notification device and an automatic accident notification system that can minimize the occurrence of defects due to an accident.

The transmitting means (14) is constructed as one unit.
Therefore, retrofitting to a completed vehicle is very easy. Also, the GPS receiver (2) for detecting the position of the vehicle is very easy to retrofit to the completed vehicle. Therefore, the in-vehicle accident automatic notification device can be lent.

For example, if the vehicle-mounted accident automatic notification device is rented out at the entrance of an expressway, the vehicle-mounted accident automatic notification device can be installed even in a vehicle to which a collision sensor or a vehicle position detection sensor is not previously attached. . Therefore, considering that there is a vehicle to which the automatic accident notification device is preliminarily installed, the automatic accident notification device can be mounted on all vehicles traveling on the highway. Therefore, even if any of the vehicles causes an accident, it is possible to report to the police station or the fire station almost at the same time as the occurrence of the accident, so that it is possible to minimize the occurrence of defects due to the accident.

At 4), radio waves containing accident information are transmitted to the external communication facility (4). In this way, accident information can be transmitted to external communication facilities.
Since the information is sent to (4) almost at the same time as the occurrence of the accident, the external communication facility (4) can report the accident information to the police station and the fire department almost at the same time as the occurrence of the accident.

Further, in the external communication facility (4), when the second receiving means (42) receives the radio wave including the accident information transmitted from the on-vehicle accident automatic notification device, it is included therein. Accident information is extracted, and necessary processing is performed on the extracted accident information. Then, the processed accident information is transmitted as a radio wave. On the other hand, in another vehicle that has not caused an accident, when the transmitted radio wave is received by the first receiving means (14), the accident information included in the received radio wave is notified by the notifying means (15). ) Will be notified.

The position detecting means (23) detects the position of the vehicle on the basis of the level difference, phase difference of the converted electric signals or the transmission time difference of the radio wave to both ends of the open type line.

For example, if the transmission distance of the radio wave from the open line (20) to the converters (21a), (21b) is different, the reception level, the phase difference or the transmission time is corresponding to the distance. different. That is, the reception level decreases as the distance increases. Also, the phase advances as the distance increases. Further, the transmission time becomes longer as the distance becomes longer. Therefore, based on the reception level difference, the phase difference, or the transmission time difference, it is possible to know from which position of the open line (20) the radio wave has started to be transmitted.

As described above, in the external communication facility (30), the position of the vehicle can be detected based on the radio wave transmitted from the in-vehicle accident automatic notification device (1) almost at the same time as the occurrence of the accident, so that the accident occurs. You can report this to the police station or fire station almost at the same time as the accident. In the external communication facility (30), the detected position of the vehicle is processed as necessary and then transmitted as a radio wave.

When received in (14), the position of the vehicle included in the received radio wave is reported.

As described above, according to the above configuration, it is possible to notify the police station and the fire station of the occurrence of the accident almost at the same time as the occurrence of the accident, and also to notify other vehicles that have not caused the accident of the accident. Therefore, it is possible to minimize the occurrence of defects due to an accident. Further, since the accident occurrence position is recognized by the external communication facility (30), it is not necessary to mount the GPS receiver (2) on the vehicle for detecting the current position of the vehicle.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. <First Embodiment> FIG. 1 is a schematic block diagram showing the structure of an automatic accident notification system according to the first embodiment. This automatic accident notification system is mounted on a vehicle and automatically transmits accident information, which will be described later, as a radio wave when an accident occurs, and receives a radio wave transmitted from an operation center, which will be described later, and the orbit of the earth. In-vehicle accident notification device 3 including a GPS receiver 2 that detects the current position of the vehicle based on the propagation delay time of radio waves transmitted from a GPS (Global Positioning System) satellite

Emergency contact facility 5 including the police station and fire station to be notified of the occurrence, and the operation center 4 installed on the road.
And an information board 6 to which accident information is transmitted.

More specifically, the communication device 1 includes
A three-dimensional acceleration detection unit (hereinafter, referred to as an acceleration detection unit that functions as an acceleration detection unit that detects acceleration in all directions of the vehicle
It is simply called "acceleration detection unit". ) 11, a clock 12 for measuring the time, a control unit 13 that functions as a determination unit that creates accident information based on the output of the acceleration detection unit 11, and the like. The accident information created by the control unit 13 is used as a radio wave in the operation center. 4 included in the radio wave received by the communication unit 14, and the communication unit 14 that functions as the first transmission unit, the first reception unit and the reception unit that receives the radio wave transmitted from the operation center 4. A voice output unit 15 that functions as a notification unit that outputs the accident information that is output as voice is included.

The communication device 1 includes the acceleration detecting section 1
1. The control unit 13, the communication unit 14, and the voice output unit 15 are configured as a single unit that is housed in an extremely robust housing. For example, the unit is firmly fixed to a vehicle instrument panel or seat with screws or clips. It A semiconductor type is used for the acceleration detector 11. This is because the semiconductor type is easily miniaturized and lightweight, and is the most suitable type for mounting the acceleration detection unit 11 in one unit.

The semiconductor type acceleration sensor is a sensor in which silicon is formed into a beam shape and an electric signal corresponding to strain or capacitance change of the beam shape silicon is output. The acceleration detection unit 11 is configured by combining three semiconductor type acceleration sensors so as to detect the x-direction component, the y-direction component, and the z-direction component of the acceleration of the vehicle.

It is more preferable that the x-direction component, the y-direction component and the z-direction component of the acceleration of the vehicle can be detected by using a single piece of silicon.
The control unit 13 is composed of, for example, a microcomputer including a CPU, a RAM, and a ROM, and determines whether or not the acceleration a of the vehicle given from the acceleration detection unit 11 is a predetermined threshold value a _th or more. It has a function to determine. The threshold value a _th is set to a value that is sufficiently larger than the acceleration a detected during normal traveling, and is, for example, a _th = 19.6 (m / sec ² ). Therefore, when the acceleration a of the vehicle becomes _{equal to} or greater than the threshold value a _th , it can be determined that an accident involving a large collision has occurred.

The GPS receiver 2 is connected to the control unit 13. The GPS receiver 2 is firmly fixed, for example, at a position near the tip of the instrument panel toward the sky with a screw or a clip. The current position data of the vehicle is given to the control unit 13 from the GPS receiver 2. When the control unit 13 determines that the acceleration a of the vehicle is _{equal to} or greater than the threshold value a _th, it is determined that an accident has occurred, and the current position of the vehicle given by the GPS receiver 2 at that time, Accident information including the acceleration a corresponding to the magnitude of the accident and the time when the accident occurred and the time measured by the clock 12 is created. The created accident information is given to the communication unit 14.

The communication unit 14 responds to the accident information by
For example, processing necessary for wireless communication such as modulation and amplification is performed. Then, the accident information is transmitted to the operation center 4 as a radio wave. The operation center 4 is provided with an antenna 41 that receives radio waves transmitted from a wide area and transmits a radio wave including processed accident information, which will be described later, and processes such as demodulation of the radio waves received by the antenna 41. The accident information restored by the communication processing unit 42 that functions as a second transmitting unit, a second receiving unit, and the like that restores the accident information and performs processing necessary for wireless communication on the processed accident information. In addition, a control unit 43 that performs necessary processing and processes accident information is included.

More specifically, in the operation center 4, when the antenna 41 receives the radio wave containing the accident information, the reception processing unit 42 restores the accident information contained therein, Further, the control unit 43 identifies the accident occurrence position from the accident information. afterwards,
The operator requests the emergency contact facility 5 including the police station and the fire station to be dispatched. At this time, the accident location,
The scale of the accident and the time when the accident occurred are also transmitted at the same time.

As described above, the accident information is transmitted to the operation center 4 almost at the same time as the occurrence of the accident, and further the accident information is notified to the emergency contact facility 5. In the operation center 4, the control unit 43 also processes the accident information restored by the communication processing unit 42 for display. Specifically, information including specific road names and intersection names corresponding to the accident occurrence position is created. Then, the created information is wirelessly or wired transmitted to the information board 6 via the communication processing unit 42. At this time, it is transmitted to the information board 6 installed especially on the road near the accident occurrence position. As a result, the information board 6 displays the accident occurrence position and the accident occurrence time.

In the operation center 4, the control unit 43 further processes the accident information restored by the communication processing unit 42 into accident information for voice output. Specifically, information such as specific road names and intersection names corresponding to the accident occurrence position is created. After that, the created accident information is transmitted to another vehicle as a radio wave via the communication processing unit 42. In another vehicle that has not caused an accident, when the communication unit 14 in the communication device 1 receives the radio wave, the processed accident information is output as a sound from the sound output unit 15.

As described above, according to the accident automatic notification system of the present embodiment, the communication device 1 having the accident detection function and the accident information transmission function is constituted by one unit, and is compact for vehicle position detection. Since the GPS receiver 2 that can be used is adopted, the in-vehicle accident automatic notification device 3 can be easily retrofitted to a completed vehicle, as compared with the conventional automatic accident notification device that includes a collision sensor as each component. .
Therefore, the in-vehicle accident automatic notification device 3 can be lent.

For example, if the vehicle-mounted accident automatic notification device 3 is rented at the entrance of a highway, the vehicle-mounted accident automatic notification device 3 can be attached to all vehicles running on the highway.
Therefore, even if any vehicle causes an accident, you can report to the police station or fire station at the same time as the accident occurrence, so move the accident vehicle to a safe place (shoulder, vacant land, etc.) that does not interfere with other traffic. In addition to being able to do so, it is possible to quickly rescue the injured person.

Further, by using the information board 7, the fact that an accident has occurred is notified to other vehicles, and the fact that an accident has occurred in another vehicle is directly notified by radio, so that a secondary disaster Occurrence can be minimized. Furthermore, when renting the vehicle-mounted accident automatic notification device 3 at the entrance of the highway, the vehicle-mounted accident automatic notification device 3 can be collected at the exit of the highway, so that maintenance can be easily performed. <Second Embodiment> FIG. 2 is a schematic block diagram showing the configuration of an automatic accident notification system according to the second embodiment. In FIG. 2, the same functional portions as those in FIG. 1 are designated by the same reference numerals. This automatic accident notification system is intended for the case where the vehicle does not have a vehicle position detection function, and the vehicle is equipped with only one unit of the communication device 1. Therefore, in the communication device 1, the acceleration detection unit 1 is included in the control unit 13.
If the acceleration a detected in 1 is greater than or equal to the threshold value a _th , the acceleration a and the clock 1
Accident information including the time measured in 2 is transmitted from the communication unit 14 as a radio wave.

The radio wave transmitted from the communication unit 14 is received by the external communication facility 30. The external communication facility 30 has a leaky coaxial cable (Leaky-Coaxia) that is an open line.
l-Cable) (hereinafter referred to as “LCX”) 20 is included. A plurality of LCXs 20 are laid along the road. In addition, in FIG. 2, one LCX 20 is shown as a representative. At both ends of the LCX 20, converters 21a, 2 for converting information transmitted through the LCX 20 into electric signals
1b is connected. Each converter 21a, 21b is connected to the position detection unit 23 via a line 22a, 22b.

Radio waves containing accident information transmitted from the communication device 1 are received by the LCX 20. The radio wave containing the accident information received by the LCX 20 is transmitted toward both ends of the LCX 20 and converted into electric signals by the converters 21a and 21b. This electrical signal is line 22
It is transmitted to the position detection unit 23 via a and 22b. The above-mentioned lines 22a and 22b are connected to the position detecting unit 23, and each electric signal transmitted via the lines 22a and 22b is received, and a level detecting unit for detecting the level of each electric signal. 24a and 24b are provided.

The level detectors 24a and 24b detect the levels of the electric signals. Each detected level is given to a level difference detection unit 25 for detecting a difference between the levels, the difference is obtained, and the obtained level difference is given to a control unit 26 functioning as a position detection means or the like. To be In the control unit 26, the reception position on the LCX 20 where the radio wave including the accident information is received is specified based on the level difference. Explaining the reason why the reception position can be specified based on the level difference, the level of the electric signal varies depending on the transmission distance of the radio wave to each end of the LCX 20. That is, the level decreases as the transmission distance increases. Therefore, the reception position can be specified based on the level difference.

The control unit 26 includes level detection units 24a and 2a.
An electric signal is directly applied from any one of 4b (level detection unit 24a in the figure). The control unit 26 restores the accident information contained therein based on the electric signal. The reception position and accident information obtained by the control unit 26 are transmitted to the operation center 4.

In the operation center 4, when the communication processing section 42 receives the reception position and the accident information, the control section 43 first identifies the accident occurrence position from the reception position. Then, the accident occurrence location is notified to the emergency contact facility 5 together with the accident information, and a request for dispatch is made. Further, the accident occurrence position and the like are displayed on the information board 6 via the communication processing unit 42. Further, the accident information processed for voice output is transmitted as a radio wave to the communication device 1 of the vehicle via the communication processing unit 42 and the antenna 41.

As described above, according to the automatic accident notification system of this embodiment, the accident occurrence position can be specified at the operation center 4, so that only the communication device 1 needs to be mounted on the vehicle. Therefore, the retrofitting work to the completed vehicle can be performed more easily. Further, since the position detecting unit 23 detects the accident occurrence position, it is not necessary to provide a GPS receiver which is essential for detecting the accident occurrence position in the first embodiment.

In the first and second embodiments described above, the communication device 1 has only a function of automatically transmitting accident information as radio waves, but when renting at the entrance of a highway, for example. The fee collection function may be added to the communication device 1. Specifically, for example, a sheet of paper with an ID code unique to each entrance of the expressway is attached to the communication device 1, and the charge to be collected is calculated at the exit of the expressway based on the ID code.

According to this structure, the communication device 1 can be surely mounted on all vehicles. <Other Embodiments> The embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments. For example, in the second embodiment, the accident occurrence position is detected based on the level difference between the electric signals, but based on the phase difference between the electric signals or the transmission time difference between the two ends of the leaky coaxial cable 20 of the radio wave. You may make it detect the accident occurrence position. The phase of the electric signal advances as the transmission distance becomes longer, and the transmission time becomes longer as the transmission distance becomes longer. Therefore, the reception position of the radio wave can be specified based on the phase difference or the transmission time difference.

Various other design changes can be made within the scope of the claims.

[0044]

As described above, according to the in-vehicle accident automatic notification device or accident automatic notification system of the present invention, the acceleration detecting means, the discriminating means and the first transmitting means are constituted as one unit. Retrofitting work can be done very easily. Further, since the GPS receiver is used to detect the accident occurrence position, the retrofitting work to the completed vehicle can be easily performed. Therefore, the in-vehicle accident automatic notification device can be lent. Therefore, for example, if you rent an in-vehicle accident notification device at the entrance of a highway, you can install the in-vehicle accident notification device in all vehicles traveling on the highway. You can report to a police station or a fire station almost at the same time as an accident. Therefore, it is possible to minimize the occurrence of malfunctions due to accidents such as delay in rescue of injured persons, delay in reporting to police, and occurrence of secondary disaster.

Particularly, according to the accident automatic notification system of claim 2, the radio wave including the accident information transmitted from the external communication facility is received, and the accident information included in the received radio wave. Is notified, it is possible to notify other vehicles of the occurrence of the accident. Therefore, the occurrence of secondary disaster can be suppressed to the minimum. Further, according to the automatic accident notification system of the third aspect, the position of the vehicle can be detected in the external communication facility, so that the accident occurrence position can be recognized. Therefore, it is not necessary to provide the vehicle with means for detecting the accident occurrence position.
