Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency call system for a vehicle, and particularly to an occupant of a vehicle approaching the accident occurrence point, which can inform the occupant of the accident in the traveling direction of the vehicle. Related to the emergency call system of the vehicle.

[0002]

2. Description of the Related Art Conventionally, in a vehicle such as an automobile, when an accident occurs in the vehicle, as an emergency notification system for notifying the occurrence of the accident to the outside of the vehicle, for example, an acceleration sensor or an airbag device provided in a vehicle body is used. It is generally well known that, when it is detected that an accident has occurred in the vehicle due to operation, etc., the fact that the accident has occurred is automatically notified to the outside of the vehicle via an in-vehicle communication means. (See, for example, JP-A-51-37427). Further, as such an emergency call system, for example, as disclosed in Japanese Patent Application Laid-Open No. 4-57198, when an accident occurs in the own vehicle, for example, a vehicle-mounted navigation device recognizes the present position of the own vehicle It is known that the current position of the own vehicle recognized by the means can be automatically notified to a pre-registered contact such as a hospital, police or home. By providing such an emergency call system, even if an occupant cannot report the accident by himself / herself in the event of an accident, he / she will automatically and promptly notify the above contact information of the accident information and seek rescue as soon as possible. be able to.

On the other hand, a so-called beacon as a communication means for receiving a passing signal from a vehicle passing a road and an emergency call signal from a surrounding vehicle and transmitting and transmitting the received information within a predetermined communication range. There is known a road information transmission system in which a vehicle is installed at a road edge (road side), and useful road information can be transmitted to a running vehicle through this beacon (for example, JP-A-62-55799). (See Japanese Patent Publication). Such beacons are arranged at predetermined intervals along the road, and various road information received by one of these beacons is transmitted to surrounding vehicles or other beacons located within the communication range of the beacon. By doing so, communication from the roadside beacon to the vehicle (so-called roadside-vehicle communication), or communication from the vehicle to the roadside beacon, and further communication from this beacon to other vehicles (so-called roadside-vehicle communication), etc. You can

[0004]

By the way, when an accident such as a traffic accident occurs on the road, this accident is caused by the surrounding vehicles running near the accident site, especially the vehicle approaching the accident vehicle. It is necessary to obtain information at the earliest possible timing and to ensure access to the accident site. However, in the above-mentioned conventional emergency call system, the accident information is first notified to the contact information, and after passing through this contact information, it is adapted to be sent to the vehicle traveling on the peripheral road near the accident site. Notifications to surrounding vehicles near the accident site will be delayed accordingly.

Further, in particular, when an accident occurs on a road with few branch roads such as an expressway, in order to avoid the approach of a succeeding vehicle traveling in the same lane, it is faster, that is, the accident. It is useful to inform the accident information as far as possible from the scene.

[0006] Therefore, the present invention enables an occupant of a vehicle approaching the scene of an accident to be surely notified at the earliest possible timing that an accident has occurred in the traveling direction of the vehicle. The purpose of the invention is to provide an emergency call system for vehicles.

[0007]

Therefore, the vehicle emergency call system according to the first invention of the present application can receive an emergency call indicating the occurrence of an accident from another vehicle or a communication means installed on the roadside. In a vehicle provided with means and a vehicle position recognition means for recognizing the current position and traveling direction of the vehicle,
When the receiving means receives an emergency call indicating that an accident has occurred, the approach state of the own vehicle to the accident occurrence point is determined based on the emergency call and the recognition data by the own vehicle position recognizing means, When the vehicle is in the state, an alarm is given to the occupant of the own vehicle.

Further, the vehicle emergency call system according to the second aspect of the present invention includes a receiving means capable of receiving an emergency call indicating the occurrence of an accident from an accident vehicle or a surrounding vehicle, and an emergency call received by the receiving means. A communication means provided with a transmission means capable of transmitting within a predetermined communication range is installed on the roadside, and an emergency notification indicating that an accident has occurred is transmitted from the communication means to a vehicle that is in a state of approaching the accident occurrence point. It was done so.

[0009]

According to the first invention of the present application, the above-mentioned vehicle
(Own vehicle) is another vehicle (that is, an accident vehicle or its surrounding vehicles) or a communication means (so-called beacon) installed on the roadside,
Since it is possible to receive an emergency notification that an accident has occurred, it is possible to obtain accident information at an earlier timing than in conventional systems. In addition, the approach status of the own vehicle to the accident occurrence point (accident scene) is determined, and if the approach status is present, the occupant is alerted by issuing a warning, so that the occupant can be aware of the accident. You can certainly recognize that you are approaching the scene. That is, it is possible to avoid approaching the accident site at the earliest possible timing and prevent traffic jams. In this case, since the above-mentioned warning to the occupants is issued only when the own vehicle is approaching the accident scene, the occupants of vehicles not particularly in the approaching state are required to pay excessive attention to the accident. There is no.

Further, according to the second invention of the present application, since the emergency notification of the occurrence of the accident is transmitted via the beacon installed on the roadside, the approaching vehicle is located at a point beyond the transmission range of the accident vehicle. The above emergency call can be transmitted to the vehicle. That is, even when a vehicle approaching the accident site is some distance away from the accident site, the accident information can be transmitted at an earlier timing, and in particular, an accident can occur on a road with few branch roads such as a highway. In the event of an occurrence, a following vehicle traveling on the same lane may avoid approaching the accident site by detouring off the expressway from the nearest branch road when receiving the emergency call. It will be possible.

[0011]

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. FIG. 1 is a block diagram schematically showing the overall configuration of a vehicle emergency call system according to a first embodiment of the present invention. As shown in this figure, the vehicle according to the present embodiment is Of the so-called navigation unit 10 which can recognize the current position of the vehicle and display it on the screen together with the map information, and when receiving an emergency notification that an accident has occurred,
An emergency call determination unit 1 for determining the approach state of the own vehicle to the accident occurrence point is provided.

The navigation unit 10 is the same as that well known in the prior art, and includes a vehicle position recognizing device 12 for recognizing the current position of the vehicle, and a map information storage device 13 for storing map information. , At least the display device 14 capable of displaying the current position of the vehicle recognized by the vehicle position recognition device 12 on the screen together with the map information, and the setting of the display screen of the display device 4 by the manual operation of the occupant. And a setting input switch 15 for Then, the own vehicle position recognition device 12 and the map information storage device 1
3, the display 14 and the setting input switch 15 are all electrically connected to the controller 11.

The vehicle position recognizing device 12 is well known as a so-called on-vehicle navigation device, and is detected by a vehicle speed sensor 17 and an azimuth determined by the geomagnetism detected by the geomagnetic sensor 16. The current position of the own vehicle can be recognized from the traveling speed of the own vehicle. Instead of or together with this, for example, radio waves from a communication satellite may be received to recognize the current position and traveling direction of the vehicle. The map information storage device 13 is composed of, for example, a CD-ROM, a magnetic tape, or the like, and stores a map or the like showing the contents necessary for driving guidance of vehicles such as roads and buildings in various places. Furthermore,
The display 14 is composed of, for example, a CRT display device or a liquid crystal display device. The setting input switch 15 may be configured to be displayed on the screen of the display unit 14. Further, the controller 11 is mainly composed of, for example, a microcomputer, and based on the current position data of the vehicle input from the vehicle position recognition device 12, maps the map information corresponding to this position. The present position of the vehicle can be read out from the information storage device 13 and displayed on the screen of the display 4 together with the map information.

The emergency call judging unit 1 is mainly composed of, for example, a microcomputer, and has a receiver 2
When the vehicle receives an emergency call indicating the occurrence of an accident via the antenna device 3, the vehicle is determined as to the location of the accident based on the emergency report data and the current position data of the vehicle from the navigation unit 10. To determine whether or not they are in an approaching state. Then, when the own vehicle is approaching the own vehicle occurrence point, a voice signal for notifying this is output, and a voice warning is issued to the driver via the power amplifier 4 and the speaker 5.

The operation of the emergency call determination unit 1 will be described below with reference to the flowchart of FIG. When the system is up and running, first step #
In step 1, the receiver 2 continuously determines whether or not an emergency call indicating that an accident has occurred is received.
If it is, determine the location of the accident (Step #
2), and the current position and traveling direction of the vehicle are determined (step # 3). These determinations are performed based on the emergency call data input from the receiver 2 and the current position data of the vehicle input from the navigation unit 10. In addition, the emergency call to the effect of the above accident,
By the receiver 2, directly from the accident vehicle, from a peripheral vehicle located around the accident vehicle, or from a so-called beacon located around the accident vehicle, and further via this beacon from another vehicle or another beacon, It can be received by various routes.

Next, the above step # 2 and step # 3
In step # 4, whether the accident location (accident scene) is in the same lane as the vehicle and in the direction of travel of the vehicle, that is, the location of the accident Is determined. If the determination result is YES, a voice signal indicating that an accident has occurred in the traveling direction of the vehicle is output, and this voice signal is output to the vehicle interior via the power amplifier 4 and the speaker 5. Is output as voice. On the other hand, if the determination result in step # 4 is NO, that is, if the accident site is not located in the traveling direction of the vehicle, or if the traveling lane is different even in the traveling direction of the vehicle, then the above No such warning is given.

If the accident site is located in the traveling direction of the vehicle, although the lanes are different, a relatively weak warning is issued to the driver, for example, by lowering the voice level to warn that. You may also let us know. Further, the above-mentioned warning is not limited to voice warnings, and may be given by other means such as blinking an alarm lamp.

As described above, according to the present embodiment, the vehicle (own vehicle) is transmitted from another vehicle (that is, an accident vehicle or a vehicle around it) or a communication means (so-called beacon) installed on the roadside. It is possible to receive an emergency notification that an accident has occurred, so it is faster than the conventional system in which accident information is first notified to a specific contact and is passed around the accident site via this contact. Accident information can be obtained at timing. In addition, the accident location (accident site)
The approach state of the host vehicle to the vehicle is determined, and if the host vehicle is in the approaching state, an alarm is issued to the occupant to call attention, so the occupant can ensure that the host vehicle is approaching the accident scene. Can be recognized. In other words, it becomes possible to avoid approaching the accident site at the earliest possible timing and prevent traffic jams. In this case, since the above-mentioned warning to the occupants is issued only when the own vehicle is approaching the accident scene, the occupants of vehicles not particularly in the approaching state are required to pay excessive attention to the accident. There is no.

Next, the second aspect of the present invention using a roadside beacon
An emergency call system according to the embodiment will be described. Figure 3

A large number of B3s are installed, and vehicles M1, M2,
It is possible to convey useful road information to M3. Such beacons B1, B2, B3 are respectively arranged at predetermined locations along the road, and various road information received by one of these beacons B1, B2, B3 is located within the communication range of the beacon. Communication from the roadside beacon to the vehicle (so-called road-to-vehicle communication), or communication from the vehicle to the roadside beacon, and communication from this beacon to other vehicles (So-called vehicle-to-vehicle communication) can be performed.

In the present embodiment, when an accident such as a traffic accident occurs on the road, the beacons B1, B2, B2, The communication function of B3 is used to notify the following vehicle of this accident information as soon as possible, that is, when the following vehicle is as far away from the accident scene as possible. That is, for example,
When a vehicle M1 and a vehicle M2 running on the road have a traffic accident at a point Y, an emergency notification of the occurrence of the accident is transmitted from at least one of the two vehicles M1 and M2. This emergency call is made with beacon B1 and beacon B2.
Beacon B2, which can be received by the vehicle, but is located in the direction in which the accident occurs (that is, located behind the accident in the lane in which the accident occurred).
Displays the received emergency call data further behind in beacon B3.
And transmits an emergency notification to the effect that the accident has occurred to the vehicles passing through the beacon B3 and the surrounding vehicles M3 on the same lane.

The beacon B3 transmits the received emergency call data to a beacon (not shown) further behind and transmits the received emergency call data to a vehicle passing through the beacon B3 or a peripheral vehicle M3 on the same lane. It is possible to transmit an emergency call to the effect that an accident has occurred. In this way, by transmitting the emergency notification via the beacons B2 and B3, it is possible to notify the distant vehicle that is beyond the communication range of the accident vehicles M1 and M2 that the accident has occurred.

The operation of the emergency call system will be described below with reference to the flowchart of FIG. When the operation of the system is started, first, step # 11
Then, it is continuously judged whether or not an accident has occurred on the road, that is, whether or not an emergency notification indicating that the accident has occurred is sent.If this is YES, the accident occurrence point and its The driving lane is determined (step # 1)
2). Next, in step # 13, it is determined whether or not the beacon is located in the traveling direction with respect to the accident occurrence point (that is, behind the accident occurrence point in the lane in which the accident occurred). It Then, if the determination result is YES, an emergency call is transmitted from the beacon (step # 14), and the transmitted radio wave is received by the beacon further behind and the passing vehicle or the surrounding vehicles on the same lane. .

As described above, according to this embodiment, since the emergency notification of the occurrence of the accident is transmitted via the beacons B1, B2, B3 installed on the roadside, the accident vehicle M
The emergency notification can be transmitted to the following vehicle M3 located at a point beyond the transmission range of 1 and M2. That is, even when the vehicle M3 approaching the accident site is far away from the accident site to some extent, the accident information can be transmitted at an earlier timing. In the event of occurrence, the following vehicle M3 traveling in the same lane avoids approaching the accident site by detouring off the expressway from the nearest branch road at the time of receiving the emergency notification. You will be able to do it.
