Description

[Technical Field]

[0001] The present invention relates to an emergency rescue request system for a vehicle. [Background technology]

[0002] In recent years, cases of young children being left behind in vehicles in the hot sun have become a social problem. In this way, an in-vehicle abnormality notification system has been disclosed that, when an abnormality occurs inside a parked automobile, such as when a child is left behind inside the vehicle, automatically acquires notification destination information for communicating with a host machine at a facility or store that manages the parking lot, and automatically reports the occurrence of the abnormality to the host machine at the facility or store specified by the notification destination information (see, for example, Patent Document 1).

[0003] Furthermore, if an abnormality is discovered inside the vehicle and an external institution such as a medical institution or the police is notified in all cases, this could result in excessive reporting (control). Therefore, an occupant rescue system has also been disclosed that can suppress excessive control while increasing the protection function for people left inside the vehicle (see, for example, Patent Document 2). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2011-141581 [Patent Document 2] Patent Publication No. 2019-144640 Summary of the Invention [Problem to be solved by the invention]

[0005] However, with the above technology, even if a notification is issued by the system, it is possible that the vehicle owner or the like may not be aware of this. In addition, depending on the location of the emergency, it is possible that the owner of the vehicle receiving the rescue request may not be present near the vehicle, which could result in a considerable amount of time being required for rescuers to arrive, delaying the rescue of young children and others left behind in the vehicle.

[0006] Digital key systems are also known that use mobile devices such as smartphones as vehicle keys, and it is possible to assign a digital key to a mobile device owned by a third party, for example via the Internet, but there are also security concerns.

[0007] Therefore, the present invention has been made in consideration of the above-mentioned problems, and aims to provide an emergency rescue request system for a vehicle that requests rescue from third parties around the vehicle being rescued, thereby ensuring security and enabling quick rescue. [Means for solving the problem]

[0008] Form 1: One or more embodiments of the present invention propose an emergency rescue request system for a vehicle, which includes a rescue request processing device and an on-board device, and which requests rescue outside the vehicle when an occupant is in danger, wherein the rescue request processing device includes a peripheral terminal search unit that searches for terminals present in the vicinity of the vehicle, a rescue request transmission unit that transmits a rescue request to the terminal, a first requested person information acquisition unit that acquires information identifying a requested person who has accepted the rescue request from the terminal of the requested person, and a digital key assignment unit that grants the requestee's terminal authority to unlock the door lock after the first requested person information acquisition unit has completed information acquisition, and the on-board device includes one or more processors and one or more memories that are communicatively connected to the one or more processors, and the one or more processors acquire biometric information of the requested person when the requestee uses the unlocking authority to unlock the vehicle doors.

[Figure 5] FIG. 10 is a diagram showing a flow chart illustrating how personal information is handled after rescue according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0014] <Embodiment> An emergency rescue request system 10 for a vehicle according to this embodiment will be described with reference to FIGS.

[0015] <Configuration of Vehicle Emergency Rescue Request System 10> As shown in FIG. 1, an emergency rescue request system 10 for a vehicle according to this embodiment includes a rescue request processing device 20 and an in-vehicle device 30.

[0016] When the vehicle occupants are in danger, the rescue request processing device 20 searches for terminals around the vehicle and issues a rescue request. The rescue request processing device 20 also acquires personal information of the requestee who has accepted the rescue request, and transmits the vehicle location information. Furthermore, when the requestee approaches within a predetermined distance from the vehicle location, the rescue request processing device 20 grants the requestee's terminal authority to unlock the door lock, and determines whether the rescue is complete. The rescue request processing device 20 will be described in detail later.

[0017] The in-vehicle device 30 is a device mounted in a vehicle, and collects information on whether or not a person has been left behind in the vehicle. Specifically, the in-vehicle device 30 acquires biometric information of the requestee. Furthermore, the in-vehicle device 30 records video information during rescue operations, and locks the vehicle doors when it determines that rescue is complete based on the recorded video information. The in-vehicle device 30 will be described in detail later.

[0018] <Configuration of rescue request processing device 20> As shown in Figure 2, the rescue request processing device 20 is configured to include a peripheral terminal search unit 21, a rescue request transmission unit 22, a first requestee information acquisition unit 23, a location information transmission unit 24, a terminal approach determination unit 25, a digital key assignment unit 26, a rescue completion determination unit 27, a memory device 28, and a terminal information database 29.

[0019] The peripheral terminal search unit 21 searches for terminals (peripheral terminals 40) present in the vicinity of the vehicle. Specifically, the peripheral terminal search unit 21 searches for multiple third-party mobile terminals in order of closest distance from the vehicle being rescued, using location information such as GPS or BLE / UWB communication, based on, for example, information on specific subscribers who are subscribed to the same insurance company or information on users who use the same mobile phone company.

[0020] The rescue request transmitting unit 22 transmits a rescue request to the searched peripheral terminal 40 by using, for example, a short message service of the mobile terminal or a special application. The rescue request transmission unit 22 transmits the rescue request to a plurality of peripheral terminals 40 in order of proximity to the vehicle, for example.

[0021] The first requestee information acquisition unit 23 acquires information identifying the requestee from the peripheral terminal 40 of the requestee who has accepted the rescue request. Here, examples of information that identifies the requestee include, for example, the mobile phone number, ID information, name, date of birth, or address registered on the peripheral terminal 40 owned by the requestee.

[0022] The location information transmission unit 24 acquires the location information of the vehicle receiving rescue based on, for example, GPS location information from the location information acquisition unit 60 described later, and sends the short message of the mobile terminal to the surrounding terminal 40 by adding a URL of the map information. In addition to the short message, the application may automatically display the URL of map information along with the message.

[0023] The terminal approach determination unit 25 determines whether the requestee has approached the vehicle within a predetermined distance. Specifically, the terminal approach determination unit 25 determines, for example, using GPS location information of the peripheral terminal 40 owned by the requested person, whether the peripheral terminal 40 owned by the requested person has come within a predetermined distance of the vehicle being rescued. Here, the predetermined distance refers to, for example, a distance at which the terminal of the requestee (requestee) can immediately carry out rescue. In addition, the terminal approach determination unit 25 may, for example, transmit temporary key information to a peripheral terminal 40 owned by the requested person when transmitting location information of the vehicle being rescued, and the vehicle being rescued may detect the temporary key information from the peripheral terminal 40 owned by the requested person, thereby determining that the peripheral terminal 40 owned by the requested person has approached the vehicle being rescued to a predetermined distance.

[0024] After the first requested person information acquisition unit 23 has completed information acquisition, the digital key granting unit 26 grants the peripheral terminal 40 owned by the requested person the authority to unlock the door lock when the peripheral terminal 40 owned by the requested person approaches within a predetermined distance to the location of the vehicle being rescued. Specifically, for example, a digital key as digital information is given to the peripheral terminal 40 owned by the requestee.

[0025] The rescue completion determination unit 27 determines the completion of rescue based on video information during rescue operations. Then, when the rescue completion determination unit 27 determines that the rescue is completed, for example, it transmits a signal to the ECU of the vehicle to lock the vehicle doors, and the vehicle doors are locked. In addition, the rescue completion determination unit 27 may determine that the rescue is complete, for example, when the person being rescued and the person being rescued who was left behind in the vehicle are no longer visible in the video footage of the rescue operation taken by a vehicle camera or the like mounted on the vehicle. The requestee may also determine that the rescue is complete based on the completion report.

[0026] The storage device 28 stores video information during rescue operations, biometric information such as fingerprint information of the requestee, and the like. Specifically, the storage device 28 can be exemplified by, for example, a hard disk drive (HDD) or a solid state drive (SSD) provided on a server.

[0027] The terminal information database 29 is a database that stores terminal information of third parties that are search targets when the peripheral terminal search unit 21 searches for portable terminals owned by third parties as candidates for recipients of a rescue request. Specifically, examples of terminal information database 29 include a database that stores information on specific subscribers who are insured with the same insurance company, or information on users who use the same mobile phone company. Furthermore, the terminal information database 29 may be, for example, a database that stores terminal information of members of a community group registered on the premise that they will rescue each other if the occupants of a vehicle being rescued get into a dangerous situation, a database that stores terminal information of people who register when purchasing a car, or a database that stores public personal information. The owner of the vehicle to be rescued may specify in advance the terminal information database to be searched.

[0028] On the other hand, since the terminal information database 29 is a database that stores terminal information for making highly urgent rescue requests when occupants in a vehicle being rescued are in a dangerous situation, it is not limited to a database of a single piece of terminal information, but may be a database of multiple pieces of terminal information in order to cover more information.

[0029] <Configuration of the in-vehicle device 30> As shown in FIG. 2, the in-vehicle device 30 is configured to include one or more processors 70, one or more memories 90 communicatively connected to the one or more processors 70, a location information acquisition unit 60, and a shooting information recording unit 80.

[0030] The processor 70 controls the entire in-vehicle device 30 in accordance with a control program stored in a memory 90, which will be described later. In this embodiment, the processor 70 particularly executes the functions of a detection unit 71, a second requested person information acquisition unit 72, an image capture information transmission unit 74, a door lock signal transmission unit 75, and the like, which will be described later.

[0031] The memory 90 includes a ROM (Read Only Memory), a RAM (Random Access Memory), etc. The ROM stores the above-mentioned control programs, etc., and the RAM stores various data, etc.

[0032] The position information acquisition unit 60 detects the position information of the vehicle itself from, for example, a GPS receiver, and transmits the position information of the vehicle itself to the position information transmission unit 24 of the rescue request processing device 20 .

[0033] The photographed information recording unit 80 records, in one or more memories 90, video information during rescue operations from the start to the end of the rescue operation, which is captured by an in-vehicle camera or the like, for example. Specifically, video images of the rescue operation from the start to the end are recorded in, for example, a ROM (Read Only Memory) or a RAM (Random Access Memory).

[0034] <Processor 70 Configuration> As shown in FIG. 2, the processor 70 includes a detection unit 71, a second requestee information acquisition unit 72, an image capture information transmission unit 74, and a door lock signal transmission unit 75.

[0035] The detection unit 71 detects whether or not there is a person left in the vehicle. Specifically, for example, when the detection unit 71 detects that a small child has been left behind in a vehicle based on video information captured by a vehicle camera or the like mounted on the vehicle, even though the engine is stopped, the detection unit 71 detects that a small child has been left behind in the vehicle.

[0036] The second requestee information acquisition unit 72 acquires the biometric information of the requestee. Specifically, for example, when the requestee touches the door handle to open the door, fingerprint information as the requestee's biometric information is obtained from a fingerprint reader or the like attached to the door handle.

[0037] The photographic information transmission unit 74 transmits the video information during the rescue operation stored in one or more memories 90 via a network to a storage device 28, such as an HDD (Hard Disc Drive) or SSD (Solid State Drive) on a server.

[0038] When it is determined that the rescue is complete, the door lock signal transmitting unit 75 transmits, for example, a signal to lock the vehicle doors to an ECU (Electronic Control Unit) of the vehicle.

[0039] <Processing of Vehicle Emergency Rescue Request System 10> The processing of the vehicle emergency rescue request system 10 according to this embodiment will be described with reference to FIGS.

[0040] <Processing up to rescue> As shown in FIG. 3, when the owner of the vehicle being rescued leaves the vehicle (step S200), the detection unit 71 detects whether or not a person has been left behind in the vehicle, for example, from video information from a vehicle camera mounted on the vehicle being rescued (step S201). Then, when the detection unit 71 detects that a person has been left in the vehicle ("YES" in step S201), it contacts the rescue request processing device 20 (step S202).

[0041] On the other hand, if the detection unit 71 does not detect a person left behind in the vehicle ("NO" in step S201), it determines that the rescue of the person left behind has been completed, and returns to step S201 and enters a standby state.

[0042] The peripheral terminal search unit 21 of the rescue request processing device 20 that has received the contact identifies the location information of the peripheral terminal 40 owned by the third party, for example, using a GPS location information system, based on the third party's terminal information stored in the terminal information database 29, and performs a search (step S203).

[0043] The rescue request transmitting unit 22 of the rescue request processing device 20 makes a rescue request for the person left behind in the vehicle to the peripheral terminals 40 owned by the third parties found in step S203 (step S204).

[0044] If the third party (requestee) who receives the rescue request accepts the rescue request ("YES" in step S205), personal information such as address registered on the peripheral terminal 40 owned by the requestee is sent to the first requestee information acquisition unit 23 of the rescue request processing device 20 along with a notification of acceptance (step S206). When the rescue request processing device 20 makes a rescue request in step S204, the requestee is asked to agree to the transmission of personal information of the requestee to the rescue request processing device 20, along with the consent to the rescue request. If the third party (requestee) who receives the rescue request does not accept the rescue request ("NO" in step S205), the peripheral terminal search unit 21 of the rescue request processing device 20 will once again search for peripheral terminals 40 owned by the third party around the vehicle (step S203).

[0045] The location information transmission unit 24 of the rescue request processing device 20 receives the location information of the vehicle for which rescue is being requested from the location information acquisition unit 60 of the in-vehicle device 30, and transmits the location information of the vehicle for which rescue is being requested to the peripheral terminal 40 owned by the requestee who has accepted the rescue request (step S207). Then, when the requestee approaches the vehicle based on the location information of the vehicle for which rescue is being requested, the terminal approach determination unit 25 of the rescue request processing device 20 determines, for example, using GPS location information, whether the peripheral terminal 40 owned by the requestee has approached within a predetermined distance to the location of the vehicle for which rescue is being requested (step S208).

[0046] If the terminal approach determination unit 25 of the rescue request processing device 20 determines that the peripheral terminal 40 owned by the requestee has come within a predetermined distance to the location of the vehicle for which rescue is being requested ("YES" in step S208), the digital key granting unit 26 of the rescue request processing device 20 grants the digital key of the vehicle for which rescue is being requested to the peripheral terminal 40 owned by the requestee (step S209).On the other hand, if the terminal approach determination unit 25 of the rescue request processing device 20 determines that the peripheral terminal 40 owned by the requestee has not come within a predetermined distance to the location of the vehicle for which rescue is being requested ("NO" in step S208), the process returns to its original state and the device waits.

[0047] Also, as shown in FIG. 4, when the requestee unlocks the vehicle door lock using the digital key provided to him / her (step S301), and the requestee touches the door handle to open the door, the second requestee information acquisition unit 72 of the in-vehicle device 30 acquires biometric information such as the requestee's fingerprint information from, for example, a fingerprint reader attached to the door handle (step S302). Then, the second requestee information acquisition unit 72 of the in-vehicle device 30 transmits the acquired biometric information to the storage device 28 (step S303).

[0048] When the requestee opens the door and starts rescue operations, the photographing information recording unit 80 photographs the rescue operations, for example, using a camera mounted on the vehicle (step S304), and records the photographed video information in memory 90. Furthermore, the photographing information transmitting unit 74 transmits the photographed video information to the storage device 28 as needed (step S305).

[0049] The rescue completion determination unit 27 of the rescue request processing device 20 determines, based on the video information during the rescue operation, whether the requestee has completed rescuing the person left behind in the vehicle (step S306). If the rescue completion determination unit 27 determines that the rescue is complete ("YES" in step S306), the door lock signal transmission unit 75 transmits, for example, a signal to lock the vehicle doors to the ECU of the vehicle requesting rescue, and locks the vehicle doors (step S307). At that time, if a rescue request has been made to another third party, the rescue request processing device 20 notifies the peripheral terminal 40 owned by the other third party that the rescue is complete (step S308).

[0050] On the other hand, if the rescue completion determination unit 27 of the rescue request processing device 20 determines that the rescue is not complete ("NO" in step S306), the rescue operation for the requestee is continued to be photographed (step S304).

[0051] <Processing after rescue is completed> Next, the flow after the rescue is completed will be explained using FIG. The owner of the vehicle requesting rescue checks whether any items have been stolen from the vehicle when the rescue operation is carried out (step S401). If the owner of the vehicle requesting rescue is found to have stolen property ("YES" in step S402), the personal information of the requested person that was sent to the memory device 28 of the rescue request processing device 20 during the rescue operation is stored (step S403). Then, for example, the police access the personal information stored in the storage device 28 (step S404) and use the personal information in an investigation into the theft of the personal information. Alternatively, for example, the personal information stored in the storage device 28 may be sent to an external organization 50, such as an insurance company, at a different location for storage, and may be used to locate stolen items.

[0052] On the other hand, if the confirmation of the owner of the vehicle requesting rescue reveals that no items have been stolen ("NO" in step S402), or, for example, when the investigation is completed, the rescue request processing device 20 deletes the personal information of the requestee that was sent to the storage device 28 (step S405).

[0053] <Actions and Effects> As described above, the vehicle emergency rescue request system 10 according to this embodiment includes a rescue request processing device 20 and an in-vehicle device 30. The rescue request processing device 20 includes a peripheral terminal search unit 21 that searches for terminals present in the vicinity of the vehicle, a rescue request transmission unit 22 that transmits a rescue request to the terminal, a first requested party information acquisition unit 23 that acquires information identifying a requestee who has accepted the rescue request from the terminal of the requestee, and a digital key granting unit 26 that grants door unlock authority to the terminal of the requestee after the first requested party information acquisition unit 23 has completed information acquisition. The in-vehicle device 30 includes one or more processors 70 and one or more memories 90 communicably connected to the one or more processors 70. The one or more processors 70 acquire biometric information of the requestee when the requestee unlocks the vehicle doors using the unlocking authority. Also, video information during rescue activities from the start to the end of the rescue is recorded in one or more memories 90, and when it is determined that the rescue is completed based on the video information, the vehicle doors are locked. Therefore, even if there are no people around the vehicle requiring rescue and the alarm from the vehicle requiring rescue goes unnoticed, or even if the owner of the vehicle requiring rescue or the store where the vehicle requiring rescue is parked does not notice the emergency call from the vehicle requiring rescue, quick rescue can be achieved while ensuring security. Furthermore, when requesting rescue in an emergency, it may be difficult to find the peripheral terminal 40 of a third party, or it may be difficult to find a requestee who will accept the rescue request. In this case, by appropriately selecting a database that stores information on the terminal to which the rescue request is to be sent depending on the situation, it is possible to expand the search target for peripheral terminals 40 of third parties to whom an emergency rescue request is to be made. This makes it easier to get approval for a rescue request.

[0054] Furthermore, on the condition that the peripheral terminal 40 owned by the requested person approaches the location of the vehicle requesting rescue within a predetermined distance, the digital key granting unit 26 grants the peripheral terminal 40 owned by the requested person the authority to unlock the door lock. This ensures stronger security.

[0055] The one or more processors also capture a biometric fingerprint of the requestee when the requestee opens the door of the vehicle from which the requestee is requesting assistance. This makes it easier to identify the culprit from the acquired biometric information of a third party even if the victim is a victim of theft or other crime.

[0056] <Modification> As a variation different from the above embodiment, before executing the processing of this embodiment, if the vehicle emergency rescue request system 10 detects that a person has been left behind in a vehicle, it may first emit an alarm sound from an alarm device or the like installed in the vehicle requesting rescue, and request rescue from those in the vicinity, before sending a rescue request to a peripheral terminal 40 owned by a third party for the person left behind in the vehicle. Furthermore, if an alarm is sounded but no rescue is performed, the system may detect whether the temperature inside the vehicle has risen to a level that puts the person left behind in danger, and if a rise in temperature inside the vehicle is detected, an emergency call may be made to, for example, the mobile terminal of the owner of the vehicle requesting rescue, or to a store or other location where the owner of the vehicle requesting rescue has parked their vehicle, informing them that a person has been left behind in the vehicle. In this way, by making rescue requests in stages according to the degree of urgency, excessive emergency requests can be reduced, leading to faster rescues and an increased chance of successfully saving lives. Furthermore, by having the rescue request processing device 20 make an emergency call to request rescue from external organizations such as insurance companies that have been registered in advance, in addition to making a rescue request to a peripheral terminal 40 owned by a third party, it is expected that lives can be saved more reliably from multiple angles.

[0057] Furthermore, instead of sending a rescue request directly from the rescue request transmitting unit 22 of the rescue request processing device 20 to multiple peripheral terminals 40, a rescue request may be propagated from a peripheral terminal 40 to another nearby peripheral terminal 40 in a bucket relay fashion using multi-hop communication between people whose identities are known and who are, for example, subscribers of the same mobile phone company. According to this method, a peripheral terminal 40 can detect other peripheral terminals 40 while also making a rescue request, thereby enabling an efficient rescue request.

[0058] The embodiments of the present invention have been described above in detail with reference to the drawings, but the specific configuration is not limited to these embodiments, and includes designs within the scope of the present invention that do not deviate from the gist of the present invention. For example, in this embodiment, the vehicle-mounted device 30 is described as being equipped with a memory 90, a photographing information recording unit 80, and a door lock signal transmitting unit 75, but the memory 90, the photographing information recording unit 80, and the door lock signal transmitting unit 75 may also be equipped in the rescue request processing device 20.
