Description

[Technical Field]

[0001] The present invention relates to an accident information distribution system, and more particularly to a system for distributing information on collisions between vehicles and pedestrians to third parties. [Background technology]

[0002] In recent years, many automobiles have been equipped with drive recorders, making it possible to analyze the circumstances of an accident from the footage from the drive recorder in the event of a car collision, etc. Furthermore, when autonomous driving becomes a reality in the future, it is expected that EDRs (event data recorders) will be installed as standard in autonomous vehicles and vehicles equipped with ADAS (advanced driver assistance systems), which will record the driving behavior of the vehicle before and after the accident, making it possible to analyze the accident circumstances from the vehicle's perspective.

[0003] Therefore, in the case of a collision between two automobiles, data is recorded in each vehicle, allowing the accident to be analyzed from the perspective of both colliding vehicles. In contrast, in a collision between a car and a bicycle or pedestrian, the bicycle or pedestrian is unlikely to have a recording device or other device to analyze the accident situation, and the accident situation is analyzed unilaterally based on the data recorded by the car, which could result in the bicycle or pedestrian being held unfavorably responsible for the accident. Conversely, in an accident caused by a bicycle or pedestrian running out of control or jumping into traffic, where the automobile's responsibility is minimal, there is a problem in that there are limited means of proving this. Another problem is that the recorded data from the bicycle or pedestrian's side cannot be distributed, making it impossible to distribute the data necessary for rescue.

[0004] Patent Document 1 describes an invention of a system that communicates between a mobile device (vehicle terminal) mounted on a vehicle and a device (smartphone) carried by a pedestrian, determines the possibility of a collision, and issues an alert to at least one of the vehicle driver and the pedestrian. However, the invention of Patent Document 1 transmits data before a collision accident in an attempt to avoid an accident, and does not distribute data about the accident after the accident occurs.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-32312 Summary of the Invention [Problem to be solved by the invention]

[0006] In the case of a collision between a car and a bicycle or pedestrian, no technology has been developed to date that can record the behavior of the bicycle or pedestrian before and after the accident and distribute this data together with the data recorded by the vehicle, thereby helping to analyze the accident and prove responsibility, and also simultaneously distributing both data quickly to an emergency support center, etc., to help provide medical treatment to the injured.

[0007] In view of the above situation, the present invention aims to record the behavior of bicycles and pedestrians, and in the event of a collision with a vehicle, record the behavior of bicycles and pedestrians before and after the accident, and quickly distribute the data together with the recorded data from the vehicle. [Means for solving the problem]

[0008] In order to solve the above problems, the accident information distribution system of the present invention is an accident information distribution system that distributes information acquired by a mobile device held by a pedestrian and information acquired by a vehicle terminal installed in a vehicle to other third parties when a collision accident between a pedestrian and a vehicle occurs, wherein the mobile terminal is equipped with a pedestrian side accident information acquisition unit that acquires information about the collision accident, and a pedestrian side accident information transmission unit that transmits the pedestrian side accident information acquired by the pedestrian side accident information acquisition unit to the vehicle terminal, and the vehicle terminal is equipped with a vehicle side accident information acquisition unit that acquires information about the collision accident, a pedestrian side accident information receiving unit that receives the pedestrian side accident information transmitted from the pedestrian side accident information transmission unit of the mobile terminal, a pedestrian-vehicle information association processing unit that associates the vehicle side accident information acquired by the vehicle side accident information acquisition unit with the pedestrian side accident information, and a pedestrian-vehicle information transmission unit that transmits the pedestrian side accident information associated by the pedestrian-vehicle information association processing unit to other third parties.

[0009] With the above-described configuration of the present invention, in addition to the information recorded by the vehicle before and after the accident, the information recorded by the pedestrian before and after the accident is also distributed to a third party. This has the effect of making it possible to analyze the accident and prove responsibility for the accident from the perspectives of both the vehicle and the pedestrian, and also being useful in providing first aid to anyone injured in the accident.

[0010] In addition, the pedestrian-side accident information acquisition unit of the present invention includes a self-location detection unit that detects the self-location of the mobile device, and a collision detection unit that detects a collision with the pedestrian holding the mobile device. With this configuration, the location where the pedestrian encountered the accident can be distributed, allowing for prompt rescue of the pedestrian, and by detecting the collision from the pedestrian's side, a record of the accident from the pedestrian's perspective can be distributed.

[0011] In addition, in the present invention, the third party to which the information before and after the accident recorded by the vehicle and the information before and after the accident recorded by the pedestrian is distributed is an information distribution server, which is connected to an emergency support center. With this configuration, the accident information distribution system of the present invention can be used to quickly provide relief to injured vehicle and pedestrians.

[0012] In addition, in the present invention, the emergency support center sends a rescue request to the surrounding information terminals, and the pedestrian's mobile terminal receives information about a collision accident occurring near the pedestrian's location from the emergency support center. With this configuration, the accident information distribution system of the present invention can be used to provide rescue to injured vehicles and pedestrians even more quickly.

[0013] In addition, in the present invention, the vehicle-side accident information acquisition unit includes a self-location detection unit that detects the self-location of the vehicle terminal, a collision probability calculation unit that calculates the possibility of a collision occurring in the vehicle equipped with the vehicle terminal, and a collision detection unit that detects the occurrence of a collision in the vehicle equipped with the vehicle terminal. By providing the collision probability calculation unit in the vehicle-side terminal in addition to the self-location detection unit and the collision detection unit, it is possible to prevent future accidents by having the driver learn about situations in which the possibility of a collision has occurred.

[0014] Furthermore, in the present invention, when the probability of a collision calculated by the collision probability calculation unit exceeds a threshold, the vehicle terminal transmits near-miss occurrence information to the information distribution server, and the pedestrian's mobile terminal receives the near-miss occurrence information about itself from the information distribution server. This configuration allows pedestrians to learn about situations in which the possibility of a collision with a vehicle has arisen, which can lead to the prevention of future accidents. [Effects of the Invention]

[0015] As described above, according to the present invention, in the event of a collision between a car and a bicycle or pedestrian, the behavior of the bicycle or pedestrian before and after the accident can be recorded and distributed together with the data recorded by the vehicle, which can be useful in analyzing the accident and proving responsibility, and both can be distributed simultaneously and quickly to an emergency support center or the like, which can be useful in providing medical care to injured people.

[0017] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0018] 1 is a block diagram showing an accident information distribution system of the present invention. The accident information distribution system 1 of the present invention comprises a pedestrian mobile terminal 100, a vehicle terminal 200, and an information distribution server 300, and the three parties communicate with each other.

[0019] The pedestrian mobile terminal 100 includes a pedestrian-side accident information acquisition unit 110 and a communication unit 120. The pedestrian-side accident information acquisition unit 110 includes a self-position detection unit 111 and a collision detection unit 112, and the communication unit 120 includes a transmission unit 121, which also functions as a pedestrian-side accident information transmission unit, and a reception unit 122. Information on the pedestrian's own position detected by the self-position detection unit 111 and information on the pedestrian's side collision detected by the collision detection unit 112 can be sent to the vehicle terminal 200 from the transmission unit 121, which is a pedestrian-side accident information transmission unit of the communication unit 120, as information linked to the pedestrian mobile terminal 100.

[0020] The vehicle terminal 200 includes a vehicle-side accident information acquisition unit 210, a communication unit 220, and a pedestrian-vehicle information association processing unit 230. The vehicle-side accident information acquisition unit 210 includes a self-position detection unit 211, a collision detection unit 212, and a collision probability calculation unit 213, and the communication unit 220 includes a transmission unit 221 that also functions as a pedestrian-vehicle report transmission unit, and a reception unit 222 that also functions as a pedestrian-side accident information reception unit. The vehicle-side self-position information detected by the self-position detection unit 211 and the vehicle-side collision information detected by the collision detection unit 212 are sent to the pedestrian-vehicle information association processing unit 230, together with the pedestrian-side self-position information and pedestrian-side collision information received by the reception unit 222 that also functions as a pedestrian-side accident information reception unit, and the pedestrian-vehicle information association processing unit 230 performs an association process to form pedestrian-vehicle information. The pedestrian / vehicle information processed and formed in the pedestrian / vehicle information association processing unit 230 can be transmitted to an external information distribution server from the transmission unit 221, which also functions as a pedestrian / vehicle information transmission unit.

[0021] Accident information from the vehicle side and accident information from the pedestrian side are linked and sent to an external information distribution server, which allows accident analysis from the perspectives of both the vehicle side and the pedestrian side and also proves responsibility for the accident. In addition, by connecting the external information distribution server to an emergency support center, it becomes useful for rescue efforts for injured people on both the vehicle side and the pedestrian side.

[0022] The vehicle-side accident information acquisition unit 210 of the vehicle terminal 200 also includes a collision likelihood calculation unit 213, which calculates the likelihood of a collision when another vehicle or pedestrian approaches the vehicle, even if a collision does not occur. When the collision likelihood calculation unit 213 determines that the likelihood of a collision exceeds a threshold and there is a possibility of a collision, it generates near-miss occurrence information, and the generated near-miss occurrence information is transmitted from the transmission unit 221 to the information distribution server 300. The near-miss occurrence information transmitted from the transmission unit 221 of the vehicle terminal 200 and received by the information distribution server 300 can be transmitted to the pedestrian mobile terminal 100, and the pedestrian mobile terminal 100 can receive the transmitted near-miss occurrence information via the reception unit 122. By receiving the near-miss occurrence information on both the vehicle side and the pedestrian side, both the vehicle side and the pedestrian side can learn about situations in which an accident may occur, thereby making it possible to prevent future accidents from occurring.

[0023] Next, regarding a method of utilizing the accident information distribution system of the present invention, the flow of using the system on the four-wheel (vehicle) side is shown in Fig. 2, the flow of using the system on the pedestrian side is shown in Fig. 3, and the flow of using the system of the information distribution server is shown in Fig. 4. In the flows of Figs. 2 to 4, in a branched decision (question) type step, if the answer is YES, the process proceeds to the next step immediately below, and if the answer is NO, the process proceeds in the direction of the line with the left and right arrows.

[0024] FIG. 2 is a diagram showing the flow of using the system on the four-wheeled vehicle side. This flow is primarily for safety confirmation and rescue measures for the occupants of the four-wheeled vehicle (vehicle). The flow of using the system on the four-wheeled vehicle side begins with determining whether there is a possibility of the four-wheeled vehicle colliding with a pedestrian or a bicycle (step S201). If the answer is YES, that is, if it is determined that there is a possibility of the vehicle colliding with a pedestrian or a bicycle, near-miss occurrence information is sent to the information distribution server (step S202). If the answer is NO, that is, if it is determined that there is no possibility of the vehicle colliding with a pedestrian or a bicycle, the system returns to the original state and waits until it is determined that there is a possibility of the vehicle colliding with a pedestrian or a bicycle.

[0025] Next, if it is determined that there is a possibility of a collision between the vehicle and a pedestrian or a bicycle, near-miss occurrence information is transmitted to the information distribution server (step S202), and then it is determined whether a collision has occurred (step S203). If the answer is NO, i.e., if a collision has not occurred, the process returns to step S201, and the loop of steps S201, S202, S203, S201, etc. is repeated until the answer is YES in step S203, i.e., until it is determined that a collision has occurred. If the answer is YES in step S203, i.e., if it is determined that a collision has occurred, the process proceeds to the next step, where accident occurrence information is transmitted to the information distribution server (step S204), and the information distribution server is connected to the emergency support center (step S205).

[0026] Next, the four-wheel (vehicle) terminal determines whether it has received information from a nearby smartphone, i.e., a mobile terminal owned by a nearby bicycle rider or pedestrian (step S206). If the answer is YES, that is, if information has been received from a nearby smartphone, the data that needs to be saved is saved in a storage device such as an EDR (event data recorder) of the vehicle (step S207), and the data obtained on the vehicle side and the saved information (data) from the nearby smartphone are also correlated and sent to the information distribution server (step S208).

[0027] If the answer is NO in step S206, that is, if no information has been received from the surrounding smartphones, only the data obtained on the four-wheeled vehicle side is sent to the information distribution server (step S209). The data sent in step S208 or step S209, that is, the data obtained on the vehicle side and the stored information (data) from the surrounding smartphones are associated with each other, or the data obtained on the four-wheeled vehicle side only, is sent to the emergency support center via the information distribution server, and the safety of the four-wheeled vehicle occupants is confirmed by an operator at the emergency support center (step S210).

[0028] Next, in step S210, the operator checks for safety to see if the occupants of the fourth wheel (vehicle) are responding (step S211). If the answer is YES, that is, if the occupants of the fourth wheel (vehicle) are responding, it is then checked whether the occupants of the fourth wheel (vehicle) are injured (step S212). If the answer is YES here as well, that is, if the occupants of the fourth wheel (vehicle) are not injured, audio guidance and images on how to provide first aid to the injured person are displayed to the occupants based on the operator's instructions (step S213), and this flow ends.

[0029] Returning to step S211, if the answer is NO in the confirmation of whether or not the occupants of the four-wheeled vehicle (vehicle) are responding (step S211), that is, if the occupants of the four-wheeled vehicle (vehicle) are not responding, an operator at the emergency support center will request rescue for the occupants of the four-wheeled vehicle and pedestrians to the smartphones around the four-wheeled vehicle (host vehicle) where the accident occurred (step S214). Then, this flow, which is mainly targeted at the occupants of the four-wheeled vehicle (vehicle), ends here.

[0030] Returning to step S211, if the answer is YES in the confirmation of whether or not the occupant of the four-wheel (vehicle) is responding (step S211), i.e., if the occupant of the four-wheel (vehicle) is responding, the process proceeds to the next step S212, and if the answer is NO in the confirmation of whether or not the occupant of the four-wheel (vehicle) is injured (step S212), i.e., if the occupant of the four-wheel (vehicle) is responding and is injured, the operator gives instructions on how to rescue the occupant of the four-wheel (vehicle) (step S215), and also makes a rescue request for the pedestrian to the smartphones around the four-wheel vehicle (host vehicle) (step S216). Then, this flow, which is mainly targeted at the occupant of the four-wheel (vehicle), ends here.

[0031] Figure 3 shows the flow of using the system on the pedestrian side. The flow on the pedestrian side includes cases where a pedestrian carrying a mobile terminal (smartphone) is involved in a collision accident, as well as cases where the pedestrian becomes a first responder when a collision accident occurs near the pedestrian. The flow of using the system on the pedestrian side begins with preparation for saving time-series EDR data (step S301). This is done to take into account communication delays via the information distribution server, and record time-series information from various sensors in advance.

[0032] Next, it is confirmed whether near-miss occurrence information has been received from the information distribution server (step S302). The near-miss occurrence information received here also includes the identification number of the vehicle terminal that transmitted the information. If the answer in step S302 is YES, that is, if near-miss occurrence information has been received, it is then determined whether the occurrence point is near the received collision prediction point (step S303). If the answer here is also YES, that is, if near-miss occurrence information has been received and the occurrence point is near the received collision prediction point, a near-miss alarm is transmitted (displayed) (step S304), notifying the pedestrian who is carrying the mobile terminal, and preparations are made for collision judgment for the pedestrian who is carrying the mobile terminal (step S305).

[0033] Then, in the next step, the result of the collision judgment is whether or not the pedestrian who is the owner of the mobile terminal has been hit (step S306). If the answer is YES, that is, if the pedestrian who is the owner of the mobile terminal has been hit, information is sent to the vehicle terminal with the identification number attached to the near-miss occurrence information received in step S302, that is, the vehicle terminal that transmitted the information, identifying the terminal as the accident terminal, which is the terminal that encountered the accident (step S307). This ends this flow.

[0034] Returning to step S302, if the answer is NO, i.e., if near-miss occurrence information has not been received, it is next determined whether the pedestrian carrying the mobile terminal (smartphone) can be a rescuer in the event of an accident occurring nearby, i.e., whether the mobile terminal (smartphone) can be a candidate for a rescue terminal (step S308). Details of the determination of a candidate rescue terminal here will be described later.

[0035] As a result of the determination of the rescuing terminal candidate (step S308), it is determined whether or not the device is a rescuing terminal candidate (step S309). If the answer is YES, i.e., if it is determined that the device is a rescuing terminal candidate, rescuing terminal processing is performed (step S310), and this flow ends. Details of the rescuing terminal processing will be described later. On the other hand, if the answer is NO in step S309, i.e., if it is not determined that the device is a rescuing terminal candidate as a result of the determination of the rescuing terminal candidate (step S308), the process returns to step S302, and thereafter, the loop of steps S302, S308, S309, S302, etc. is repeated until the answer is YES in step S302 or step S309, i.e., until near-miss occurrence information is received or until it is determined that the device is a rescuing terminal candidate.

[0036] Next, if the answer in step S302 is YES and the process proceeds to step S303 where the answer is NO, that is, if near-miss occurrence information is received but the source of the near-miss occurrence information is not near the predicted collision point where it was received, the process returns to step S302 and waits for a case where near-miss occurrence information is received and the source of the near-miss occurrence information is near the predicted collision point where it was received.

[0037] Next, the process proceeds to step S306, and if the answer is NO, i.e., if it is determined that no collision has occurred as a result of the collision determination, the subsequent processing is the same as if the determination in step S302 is NO, i.e., if no near-miss occurrence information has been received. To reiterate, first, a determination is made as to whether a pedestrian carrying the mobile terminal (smartphone) can be a rescuer in the event of an accident occurring nearby, i.e., whether the mobile terminal (smartphone) can be a candidate for a rescue terminal (step S311). The details of the rescue terminal candidate determination here will be described later.

[0038] As a result of the rescuing terminal candidate determination (step S311), it is determined whether or not the device is a rescuing terminal candidate (step S312). If the answer is YES, i.e., if it is determined that the device is a rescuing terminal candidate, rescuing terminal processing is performed (step S313), and this flow ends. On the other hand, if the answer is NO in step S312, i.e., if it is not determined that the device is a rescuing terminal candidate as a result of the rescuing terminal candidate determination (step S311), the flow returns to step S306, and thereafter, the loop of steps S306, S311, S312, S306, etc. is repeated until the answer is YES in step S306 or step S312, i.e., until it is determined that a collision has occurred or it is determined that the device is a rescuing terminal candidate.

[0039] Next, the above-mentioned rescue terminal candidate determination (subroutine S350) will be described. The rescue terminal candidate determination (subroutine S350) first determines whether accident occurrence information has been received from the information distribution server (step S351). The accident occurrence information determined to have been received here is sudden accident occurrence information that has not been passed through near-miss occurrence information, and therefore is presumed to be information about an accident involving another pedestrian, rather than information about a collision accident involving the pedestrian carrying the mobile terminal (smartphone). If the answer to step S351 is YES, that is, if it is determined that accident occurrence information has been received from the information distribution server, then it is determined whether the location from which the accident occurrence information was transmitted is close to the location from which the accident occurrence information was received (step S352).

[0040] If the answer to step S352 is YES, i.e., if it is determined that accident information has been received from the information distribution server and the location from which the accident information was transmitted is close to the location from which the accident information was received, the terminal is determined to be a first-aid terminal candidate, and the flow of this subroutine S350 ends and returns to the original state. Also, if the answer to step S351 or step S352 is NO, i.e., if it is determined that accident information has not been received from the information distribution server or the location from which the accident information was transmitted is not close to the location from which the accident information was received, the terminal is not determined to be a first-aid terminal candidate, and the flow of this subroutine S350 ends and returns to the original state.

[0041] Next, the above-mentioned rescue terminal processing (subroutine S370) will be described. The rescue terminal processing (subroutine S370) begins by displaying a rescue request candidate request on the mobile terminal (step S371). This display prompts the user who owns the mobile terminal to request rescue and, if possible, to respond that rescue is available. Next, it is confirmed whether the user who owns the mobile terminal responds that rescue is available, i.e., whether the user has input that rescue is available into the mobile terminal (step S372). If the answer to step S372 is YES, i.e., if it is confirmed that the user has responded that rescue is available, information indicating the rescue terminal candidate is transmitted to the vehicle terminal with the identification number assigned to the accident occurrence information received in step S351 of subroutine S350, i.e., the vehicle terminal that transmitted the information (step S373), and the subroutine S370 flow ends and returns to the original state. On the other hand, if the answer to step S372 is NO, that is, if it is not confirmed that the user has responded that rescue is possible, the flow of this subroutine S370 ends without any processing and returns to the original state.

[0042] 4 is a diagram showing the flow of use of the emergency support center system. The emergency support center first waits for receipt of emergency call data indicating that a vehicle collision accident has occurred (step S401), and monitors whether the emergency call data has been received (step S402). If the answer is NO, i.e., if the emergency call data has not been received, the process returns to step S401 and continues to monitor for receipt of emergency call data until it is received. If the answer in step S402 is YES, i.e., if the emergency call data has been received, the probability of death or serious injury of the vehicle occupants is estimated based on the information in the received emergency call data (step S403).

[0043] Next, it is confirmed whether or not there is information about the object that collided with the vehicle (step S404). The information about the object here also includes information about the probability of fatality and serious injury of the object. If the answer is YES, that is, if there is information about the object, the probability of fatality and serious injury of the occupants calculated in step S403 is transmitted to the fire department headquarters and / or the base hospital at the receiving point (step S405). Furthermore, assuming that information about the object is already available, instructions are given to the operator on how to deal with the occupants and the object based on the calculated probability of fatality and serious injury (step S406), and it is confirmed whether or not there is information about rescue collaborators (step S407).

[0044] Returning to step S404, if the answer is NO, i.e., if there is no information about the collision object, the collision object is estimated based on the information in the received emergency call data (step S408), and the collision part is estimated based on the information in the received emergency call data (step S409). Then, based on the data of the estimation results about the collision object and the collision part and other information in the received emergency call data, the probability of death or serious injury between the occupant and the collision object is calculated (step S410), and the calculated probability of death or serious injury between the occupant and the collision object is distributed to the fire department headquarters and / or the base hospital at the receiving point (step S411). Furthermore, based on the calculated probability of death or serious injury, the operator is instructed on how to deal with the occupant and the collision object (step S412), and it is confirmed whether there is information about rescue assistance (step S407).

[0045] If the answer to step S407 regarding confirmation of information on rescue cooperators is YES, i.e., if information on rescue cooperators is available, this flow at the emergency support center ends. On the other hand, if the answer to step S407 regarding confirmation of information on rescue cooperators is NO, i.e., if information on rescue cooperators is not available, the emergency support center instructs the operator on how to contact rescue cooperators based on information on nearby rescuers known to the emergency support center (step S413), and this flow at the emergency support center ends.

[0046] The above describes the manner in which the present invention can be implemented using examples, but the present invention is not limited to these examples and can, of course, be implemented in various ways within the scope of the spirit of the present invention. [Explanation of symbols]
