Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency response system and apparatus for performing necessary communication between a vehicle and a reception center when an emergency occurs.

[0002]

2. Description of the Related Art Conventionally, in the event of a traffic accident or an emergency in a vehicle, a dedicated reception center is automatically or simply operated manually through a wireless network such as a car telephone. A system for transmitting information is known.

[0003] In such a system, when there are a plurality of emergency reports, the response is made in the order in which the reports were received, or a plurality of reception center operators respond. However, there has been a problem that if a large number of reports are received with respect to the number of operators at the reception center, a sufficient response cannot be made.

In emergency situations, there are cases of minor injuries and serious injuries involving lives, and it is not sufficient to simply process in the order in which the reports were received. It is very important how you respond. For example, when a serious accident involving a human life is reported while dealing with a minor accident, simply processing the order in sequence may cause a problem that the response to a serious accident is delayed.

The present invention has been made to solve the above-mentioned problem, and has as its object to provide an emergency response system and apparatus capable of promptly and appropriately responding to an emergency.

[0006]

Means for Solving the Problems and Effects of the Invention (1) The invention according to claim 1 is characterized in that when an emergency such as an accident occurs, the emergency center (for example, the vehicle side) and the reception center side are connected. It relates to an emergency response system that performs communication,
In particular, it relates to the configuration on the emergency occurrence side.

In the present invention, for example, on the vehicle side, an output corresponding to the degree of an emergency is generated by a generating means (for example, a G sensor), and based on this output (for example, according to the magnitude of acceleration), an emergency is generated. The degree of the situation is determined, and a signal indicating the determination result is transmitted to the reception center side.

[0008] Therefore, the reception center can quickly grasp the degree of the emergency, so that, for example, it is possible to promptly arrange for an ambulance or the like. Also, even if multiple emergency calls are received at the reception center at once,
It is possible to know which emergency call should be taken in order according to the degree of emergency. Therefore, for example, even if a serious accident involving human life is reported while responding to a minor accident,
By responding according to the priority order, it is possible to prevent a problem that response of a serious accident is delayed.

(2) The invention of claim 2 exemplifies the generating means and the judging means. According to the present invention, the degree of an emergency can be determined according to the magnitude of the acceleration detected by the G sensor. (3) The invention according to claim 3 relates to an emergency response system for performing communication between an emergency occurrence side (for example, a vehicle side) and a reception center side when an emergency such as an accident occurs. It relates to the configuration on the emergency occurrence side.

According to the present invention, for example, an operation means (eg, an emergency switch) operated manually on the vehicle side
Accordingly, a signal corresponding to the degree of emergency is output, the degree of emergency is determined based on this signal, and a signal indicating the determination result is transmitted to the reception center side.

Therefore, as in the first aspect, the reception center can quickly grasp the degree of emergency, so that it is possible to promptly take measures such as arranging an ambulance. In addition, even if a plurality of emergency calls enter the reception center at one time, it is possible to know which emergency call should be taken in order according to the degree of the emergency, so that an appropriate response according to the priority order can be taken. .

(4) The invention of claim 4 exemplifies the operation means. According to the present invention, it is possible to quickly and reliably transmit the degree of an emergency by operating switches (heavy, medium, and light button switches) set according to the degree of the emergency. it can.

(5) The invention of claim 5 relates to an emergency response system for performing communication between the emergency occurrence side (vehicle side) and the reception center side when an emergency such as an accident occurs. In particular, it relates to the configuration of the reception center. In the present invention, for example, when a signal including information on the degree of emergency transmitted from the vehicle side is received, the degree of emergency is recognized from the received signal, and the response is performed based on the recognized degree of emergency. Determine the priority to be done.

That is, for example, the signal transmitted from the vehicle includes information indicating the degree of emergency,
Based on the information, the priority order from which emergency call should be handled can be determined. Therefore, even when a plurality of emergency calls are received, it is possible to respond promptly and reliably by responding according to the priority order.

Therefore, as described above, for example, even if a serious accident involving human life is reported while dealing with a minor accident, the response to the serious accident is delayed by responding according to the priority order. Can be prevented. (6) In the invention of claim 6, when the priority is determined, in addition to the information on the degree of the recognized emergency, the traffic congestion around the emergency occurrence site, the type of road, and the emergency occurrence site At least one type of information among the distance to the fire department and the reporting time is taken into account.

Thus, the priority order can be determined in consideration of the situation (road conditions, etc.) when performing an operation corresponding to an emergency, so that the priority order can be determined more accurately. For example, if there is an emergency call with a similar degree of emergency, the priority is determined in consideration of other situations, so even in the case of a later emergency call, the priority may increase, but With the limited resources (number of personnel and ambulances, etc.), the maximum effect can be achieved.

(7) The invention according to claim 7 relates to a traffic congestion situation around a site where an emergency has occurred. In this case, the priority of the traffic congestion is higher than that of the traffic congestion. As a result, those who can reach the site in a short time can quickly carry out rescue activities, so that rescue activities in other places can be carried out quickly thereafter, and the maximum effect among limited resources Can be raised.

Incidentally, in addition to the traffic congestion around the emergency occurrence site, for example, the traffic congestion on the road from the fire station to the site of occurrence may be considered. (8) The invention of claim 8 relates to the type of road. Here, the priority of expressways is higher than that of general roads.

[0019] Thereby, the rescue operation of the person who can reach the site in a short time can be promptly performed, so that the rescue operation in another place can be promptly performed thereafter. The maximum effect can be achieved.
General roads are classified into national roads, prefectural roads, and city roads, and are classified into two-lane roads, two-lane roads, and one-lane one-way roads. Increase priority. For example, the priority order is: national road> prefectural road> city road, and the priority is face-to-face traffic> one-way traffic.

(9) The ninth aspect of the present invention relates to the distance from the emergency occurrence site to the fire department. Here, when the distance is short, the priority is increased when the distance is short. As a result, those who can reach the site in a short time can quickly carry out rescue activities, so that rescue activities in other places can be carried out quickly thereafter, and the maximum effect among limited resources Can be raised.

(10) According to the tenth aspect of the present invention, regarding the reporting time, the priority of the reporting time earlier than the later reporting time is increased. As a result, the time from the reporting time to the arrival at the site can be shortened on average.

(11) According to the invention of claim 11, the determined priority is reported to an operator or a department (fire department or police department) required for the response. For example, when a plurality of emergency calls are made, the priority order is determined according to claims 6 to 10 described above.
Are determined according to the following conditions, and the determined priorities are displayed in a list on, for example, a display of the operator.

Thus, the operator can perform an appropriate process (for example, start a voice call with the vehicle or report to a fire station or police station) according to the priority order. Further, when the priorities are notified to the fire department and the police department, processing corresponding to the priorities (for example, preparation and arrangement of personnel and vehicles) can be performed in those departments.

(12) According to the twelfth aspect of the present invention, an operator or a department required for the response is notified in descending order of the determined priority. Therefore, the notified side can respond in the notified order. (13) According to the invention of claim 13, a communication line is connected to an operator or a department required for correspondence so that communication with the vehicle is possible in the order of the determined priority.

As a result, a call with the vehicle can be made promptly, so that the situation on the vehicle can be quickly and reliably grasped. (14) The invention of claim 14 exemplifies a vehicle as the emergency occurrence side.

5a, 25b and 25c are provided. "Severe": An accident that calls for an ambulance immediately "Medium": An accident with a degree of scratching "Mild": A minor accident with a car alone The classification of the degree of this emergency can be set arbitrarily. it can.

The G sensor 27 is used for determining conditions for operating an air bag (not shown). When the output of the G sensor 27 exceeds a predetermined operation determination value, The airbag operates. Therefore, when the output of the G sensor 27 exceeds this operation determination value,
It can be considered that an accident has occurred. In addition, apart from the operation determination value, a determination value (degree determination value H1, H2, H3) corresponding to the output of the G sensor 27 is provided, and as described below, the output of the G sensor 27 determines the respective degree determination value. It is set so that the degree of an accident can be determined when the number exceeds the threshold.

"H1": an accident that promptly requests an ambulance. "H2": An accident with a degree of scratching. "H3": A slight accident involving only a car. B) Next, the emergency response system according to the present embodiment Processing and the like will be described.

Processing in Apparatus on the Vehicle Side As shown in the flowchart of FIG.
At 0, the data of the current position of the vehicle acquired by the GPS receiver 5 is stored in the memory 17. Next step 11
At 0, it is determined whether or not an accident has occurred. If the determination is affirmative, the process proceeds to step 120, while if the determination is negative, the process returns to step 100.

The occurrence of an accident can be detected by various sensors. For example, a safety monitor (not shown) that detects the magnitude of the output of the G sensor 27 (when the value exceeds an airbag operation determination value) or an abnormality of other parts of the vehicle.
May be determined from the output of. Alternatively, a manual button (not shown) for notifying the occurrence of an accident may be provided, and when this button is pressed by a driver or the like, it may be determined that an accident has occurred.

In the following step 120, the degree of the accident is determined. For example, the magnitude of the acceleration (for example, longitudinal acceleration) detected by the G sensor 27 is checked, and the magnitude of the accident (severity, severity, etc.) is determined based on whether or not the magnitude of the acceleration exceeds the degree determination values H1, H2, H3. Medium, mild). In this case, it is determined that the greater the acceleration, the greater the degree of the accident.

In the following step 130, the result of the determination of the degree of the accident is set in the transmission data. Next step 14
At 0, the transmission data is transmitted to the reception center via the relay station. In that case, not only information on the degree of the accident,
The current position, personal information, vehicle information, etc. are also transmitted.

The personal information includes, for example, information that should be taken care of in the case of emergency treatment, such as the driver's age, blood type, and illness. In addition, as the vehicle information, the type of the vehicle (discrimination of a normal passenger car, a mini car, a truck, etc.)
And numbers. These pieces of information are stored in advance in a backup memory (not shown) of the ECU 3 or the like.

Alternatively, the pulse and blood pressure of the driver or the like may be monitored and the information (biological information) may be transmitted. In the following step 150, a call with the operator is enabled. Thereby, the driver or the like can inform the operator of the details of the accident in detail.

Processing in the Apparatus on the Reception Center Side As shown in FIG.
Receives emergency communication and data communication from the user and stores the data. In the following step 210, it is determined whether there is another notification within a predetermined period (for example, within N seconds). If a positive determination is made here, the process proceeds to step 220,
On the other hand, if a negative determination is made, the process proceeds to step 260.

In step 260, since there is no report from the other party, the state is switched to a state where a voice call can be made with the reporter, and the present process is ended once. On the other hand, in step 220, since there is communication from another, one or more emergency calls from the other are received.

In the following step 230, a priority order indicating which emergency call should be dealt with among a plurality of emergency calls is determined in consideration of various information such as the degree of an accident and the place of occurrence as shown in FIG. decide. The method of determining the priority will be described later in detail.

In the following step 240, the priority of the emergency call is notified to the operator, for example, by displaying it on the display in front of the operator. Next step 2
At 50, the emergency call with the higher priority is switched to voice communication with the operator, and the present process is ended once.

Thereafter, the operator confirms the situation of the user by talking with the vehicle side (user) in which the accident has occurred, and, if necessary, contacts a fire department, a police department, a tow dealer or the like. Next, an algorithm for determining the priority order will be described.

The determination of the priority order may be automatically performed by the computer at the reception center in accordance with the information transmitted from the vehicle and the information on the surrounding situation checked at the reception center. An operator or the like may manually or partially perform all or some of these conditions.

The conditions for determining the priority are as follows:
The following are mentioned. (1) Emergency level information transmitted In this order, (high ←) severe, medium, and mild (→ low) in this order, such that the higher the degree of an accident, the higher the priority Is set.

(2) Traffic Congestion Around the Emergency Site The priority of traffic congestion is set higher than that of traffic congestion. (3) Type of road The higher the traveling speed, the higher the priority is set. For example, the priority order is set as follows: expressway> general road, national road> prefectural road> city road, two-way traffic> one-way.

(4) Distance from Emergency Site to Fire Station The closer the distance from the emergency site to the fire station, the higher the priority is set. Note that this distance is obtained by calculating the distance between the current vehicle position and the fire department where the vehicle position is in the coverage area. The distance is preferably a distance that can be obtained as navigation information, but a straight-line distance may be used for simplicity.

(5) Reporting Time The earlier the reporting time, the higher the priority. However, if a certain time or more has elapsed, this condition is ignored. In the conditions (1) to (5), for example, the higher the priority, the higher the priority. However, the priority may be appropriately changed.

More specifically, the conditions are checked starting from the condition (1). If the conditions are the same (for example, severe conditions), the following condition (2) is determined. Then, the determination condition may be further subdivided as determined by the condition (3). Also, for example, by weighting each condition,
A value can be obtained from a predetermined calculation formula, and the priority can be determined based on the magnitude of the value.

C) As described above, in this embodiment, when a plurality of emergency situations occur in a short time, the priorities are determined and the priority is dealt with in descending order of priority. This has the effect that emergency response can be performed efficiently in the resources (such as the number of personnel and ambulances).

Therefore, even if a serious accident involving human life is reported while dealing with a minor accident, it is possible to prevent a situation in which the response to the serious accident is delayed. Further, in the present embodiment, the degree of the accident is automatically transmitted according to the output of the G sensor 27, so that even if the driver or the like cannot take appropriate measures, there is an advantage that the approximate situation of the accident can be grasped. is there. (Embodiment 2) Next, Embodiment 2 will be described, but description of the same parts as in Embodiment 1 will be omitted.

This embodiment is characterized in the processing in the device on the vehicle side. First, as shown in the flowchart of FIG.
In step 300, the data of the current position of the vehicle acquired by the GPS receiver 5 is stored in the memory 17. In the following step 310, it is determined whether or not an accident has occurred. If the determination is affirmative, the process proceeds to step 320, while if the determination is negative, the process returns to step 300.

The occurrence of an accident can be determined by operating the emergency switch 25. For example, buttons 25a-c
If any of the buttons is pressed, it can be considered that an accident has occurred. Further, the degree of the accident can be known from which of the buttons 25a to 25c of the emergency switch 25 is pressed.

In addition, when the output of the G sensor 27 exceeds the operation determination value, it may be considered that an accident has occurred, and other various safety monitors can be used. In step 320, the judgment result of the degree of the accident is set in the transmission data.

In the following step 330, the transmission data is
Send it to the reception center via the relay station. In that case,
It transmits not only the accident degree information but also the current position, personal information, vehicle information, and the like. In the following step 340, a call with the operator is enabled. Thereby, the driver or the like can inform the operator of the details of the accident in detail.

According to this embodiment, the same effects as those of the first embodiment can be obtained, and since the occurrence and the degree of the accident are transmitted by operating the emergency switch 25, the reliability of the information is high. It should be noted that the present invention is not limited to the above-described embodiment at all, and it goes without saying that the present invention can be implemented in various modes without departing from the present invention.

(1) For example, the determination result of the degree of emergency based on the G sensor and the information of the degree of emergency by the emergency switch may be transmitted together. Thereby, the reliability of the information is further improved. (2) In the first and second embodiments, the case where an accident occurs in a vehicle is described as an example. However, when an accident occurs in a place other than the vehicle (for example, in a house), an emergency occurs. You may make it report.

(3) Further, in the first and second embodiments, the case of a vehicle accident has been taken as an example. However, when a disease or the like occurs in a vehicle (or other than a vehicle), an emergency report may be made. Good. In this case, the emergency switch may be provided with the following heavy, medium, and light buttons, and an emergency call may be made by pressing any of the buttons.

“Severe”: A degree to request an ambulance immediately “Medium”: A degree requiring assistance “Mild”: A degree to feel sick
