Hereinafter, with reference to the attached drawings, embodiments of a transport support system 1, a transport support apparatus 10, a transport support method, and a program according to the present invention will be described in detail. In addition, this invention is not limited by the following embodiment.

[First embodiment]
FIG. 1 is a schematic diagram illustrating an outline of a conveyance support system according to the first embodiment. FIG. 2 is a block diagram illustrating a configuration example of the transport support system according to the first embodiment. When the occupant's body is in an abnormal state, the transport support system 1 selects a route to the meeting point between the emergency moving body and the vehicle and causes the vehicle to travel to the meeting point with the emergency moving body. In the conveyance support system 1, the conveyance support device 10, the junction point selection device 20, and the detection unit 100 are connected so as to be able to transmit and receive data. In the present embodiment, the vehicle can be driven automatically. In the present embodiment, a description will be given assuming that an abnormality has occurred in the driver among the occupants of the vehicle.

The ambulance includes ambulances and emergency life-saving helicopters. In the present embodiment, the ambulance moving body will be described as an ambulance.

The detection unit 100 detects the state of a vehicle occupant. For example, the detection unit 100 is a camera that captures an occupant. For example, the detection unit 100 is a sensor that detects occupant biological information. For example, the sensor may be installed in a vehicle including a steering wheel or a dashboard, or may be a wearable terminal worn by a passenger on the body.

The detection unit 100 includes, as occupant biological information, at least of pupil information, line-of-sight information, blink information, pulse information, body temperature information, respiratory information including presence / absence of breathing, and consciousness information including presence / absence of consciousness. Get one. More specifically, for example, the pupil information is acquired by performing image processing on video data of an occupant's eye imaged by a camera arranged in the vehicle. For example, the line-of-sight information is acquired from the detection result of the line-of-sight detection device that detects the line of sight of the passenger. For example, the blink information is acquired by performing image processing on video data of an occupant's eye imaged by a camera disposed in the vehicle. For example, the pulse information is acquired from detection data detected by a sensor disposed on the steering wheel. For example, body temperature information is acquired from infrared video data of the occupant's face taken with an infrared camera placed in the vehicle. For example, the breathing information is acquired by performing image processing on video data of an occupant's face imaged by a camera disposed in the vehicle. For example, the consciousness information is obtained by performing image processing on video data of the occupant's face taken by a camera disposed in the vehicle. The detection unit 100 outputs the biological information detected in this way to the conveyance support apparatus 10 as detection data.

Furthermore, the detection unit 100 may acquire, as occupant biometric information, convulsion information indicating that the body is convulsed and massive bleeding information indicating that a large amount of blood is bleeding. The detection unit 100 may include the convulsion information and the massive bleeding information in the detection data and output them to the conveyance support apparatus 10. For example, the convulsion information and the massive bleeding information are acquired by performing image processing on video data of a passenger photographed with a camera arranged in the vehicle.

The conveyance support device 10 is mounted on a vehicle. The conveyance support apparatus 10 may be mounted as one of the functions of the vehicle navigation system. In this embodiment, the conveyance support apparatus 10 is mounted as a function of a navigation system mounted on the vehicle. The conveyance support apparatus 10 is an arithmetic processing apparatus configured by, for example, a CPU (Central Processing Unit). The conveyance support apparatus 10 executes instructions included in a program stored in a storage unit (not shown). The conveyance support apparatus 10 will transmit abnormality information and the present position information of a vehicle with respect to the joining point selection apparatus 20, if a passenger | crew's abnormality is detected. When the conveyance support device 10 acquires the merge point information from the merge point selection device 20, the conveyance support device 10 searches for a route to the merge point. Furthermore, the conveyance assistance apparatus 10 controls the vehicle to automatically travel to the junction. The conveyance support apparatus 10 includes a detection data acquisition unit 11, a vehicle position information acquisition unit 12, a determination unit 13, a communication unit 14, a route search unit 17, an automatic driving control unit 18, and a storage unit 19. .

The detection data acquisition unit 11 acquires detection data that is biological information of a vehicle occupant from the detection unit 100. The detection data acquisition unit 11 outputs the acquired detection data to the determination unit 13.

The vehicle position information acquisition unit 12 acquires current position information of the current position of the vehicle. In the present embodiment, the vehicle position information acquisition unit 12 acquires the current position information of the vehicle acquired by a GPS (Global Positioning System) receiver mounted on the vehicle. The vehicle position information acquisition unit 12 outputs the acquired current position information to the determination unit 13, the route search unit 17, and the automatic driving control unit 18.

The determination unit 13 determines whether the occupant's body is estimated to be in an abnormal state based on the detection data acquired by the detection data acquisition unit 11. An abnormal state is a state in which an occupant needs emergency transport. The condition that requires emergency transport is, for example, when there is no consciousness, when breathing stops, when there is no pulse, when the body is spasm, when there is a large amount of bleeding, the body temperature decreases When you are.

The determination unit 13 determines the presence or absence of consciousness from the consciousness information, pupil information, line-of-sight information, and blink information included in the detection data. The determination unit 13 determines that respiration is stopped from the respiration information included in the detection data. The determination unit 13 determines that there is no pulse from the pulse information included in the detection data. The determination unit 13 determines that the body is convulsive from the convulsion information included in the detection data. The determination unit 13 determines that there is a large amount of bleeding from the large amount of bleeding information included in the detection data. The determination unit 13 determines that the body temperature is decreasing from the body temperature information included in the detection data.

When it is determined that there is no consciousness, when it is determined that breathing is stopped, when it is determined that there is no pulse, when the determination unit 13 determines that the body is convulsed, a large amount of bleeding When it is determined that the vehicle body is being operated or when it is determined that the body temperature is decreasing, it is determined that the passenger's body is estimated to be in an abnormal state. The determination unit 13 outputs the determination result to the communication unit 14 together with abnormality information that is detection data. The determination unit 13 outputs the determination result to the automatic operation control unit 18.

Anomaly information is generated based on detection data. Abnormal information is occupant's biological information useful for diagnosis by a doctor. For example, the abnormality information is video sensed by the occupant, data detected by a sensor, or the like.

The communication unit 14 includes a transmission unit (first transmission unit) 15 and a reception unit (first reception unit) 16.

When the determination unit 13 determines that the occupant's body is estimated to be in an abnormal state, the transmission unit 15 transmits the current position information acquired by the vehicle position information acquisition unit 12 and the abnormality information to the joining point selection device 20. To do.

The destination joining point selection device 20 is placed in the primary hospital when the occupant's primary hospital is stored in the storage unit 19 in advance or can be acquired from a portable electronic device carried by the occupant. The junction point selecting device 20 may be used. Or the confluence | merging point selection apparatus 20 of a transmission destination is good also as the confluence | merging point selection apparatus 20 installed in the nearest emergency hospital from the present position information of a vehicle.

The receiving unit 16 receives the merge point information of the merge point between the vehicle and the ambulance from the merge point selection device 20. The receiving unit 16 outputs the received joining point information to the route search unit 17.

The route search unit 17 searches for a route to the joining point based on the joining point information and the current position information received from the joining point selection device 20. A method for searching for a route can use a known route search method, and is not limited.

If the determination result of the determination unit 13 is that the occupant's body is estimated to be in an abnormal state, the automatic driving control unit 18 stops the vehicle at a safe place if the vehicle is running. Thus, a control signal is output to an operation control unit (not shown) of the vehicle.

The automatic driving control unit 18 outputs a control signal to the driving control unit so that the vehicle travels to the junction based on the route information searched by the route searching unit 17.

The storage unit 19 stores data and various processing results required for various processes in the transport support apparatus 10. The storage unit 19 is, for example, a semiconductor memory device such as a RAM (Random Access Memory), a ROM (Read Only Memory), a flash memory, or a storage device such as a hard disk, an optical disk, or an external storage device via a network. Alternatively, an external storage device that is wirelessly connected via a communication device (not shown) may be used.

The junction point selection device 20 is installed in, for example, a hospital, a fire department, or an emergency transport support facility including an authority having an authority to select an emergency transport destination or issue a dispatch command for an ambulance. In the present embodiment, the joining point selection device 20 will be described as being installed in a hospital (emergency transport support facility). The junction point selection device 20 is an arithmetic processing device configured with, for example, a CPU. The junction point selection device 20 executes instructions included in a program stored in a storage unit (not shown). The junction point selection device 20 selects a junction point between the vehicle and the ambulance according to the abnormality information received from the conveyance support device 10, and transmits the junction point information to the conveyance support device 10. The junction point selection device 20 includes a reception unit (second reception unit) 21, a junction point selection unit 22, and a transmission unit (second transmission unit) 23.

The receiving unit 21 receives the abnormality information and the current position information of the vehicle from the conveyance support device 10. The receiving unit 21 notifies the doctor of the received abnormality information. The receiving unit 21 outputs the received current position information of the vehicle to the joining point selecting unit 22.

The doctor can check the notified abnormality information and diagnose the occupant's symptoms. The doctor diagnoses the occupant's symptoms including whether it is better to dispatch an ambulance, in other words, whether the emergency level is high. Diagnosis result information, which is a result of diagnosis by the doctor, may be transmitted to the conveyance support apparatus 10 from a diagnosis device or the like used by the doctor for diagnosis, or the doctor makes a diagnosis via the input device of the junction point selection unit 22. You may input result information directly.

The confluence point selection unit 22 selects a confluence point between the ambulance and the vehicle transported to the hospital based on the current position information and abnormality information of the vehicle received by the reception unit 21. When the diagnosis result information of the occupant by the doctor is “high urgency”, the merging point selection unit 22 selects a merging point when the occupant is transported to the hospital.

A junction is an intermediate point between the location of a hospital and the current position of a vehicle, for example, a parking lot such as a public facility, a park, a shoulder on a road where parking can be stopped, and a passenger can be safely moved to an ambulance It is preferable to select an appropriate point. The joining point is preferably a point where the occupant can join the ambulance the earliest. In other words, the merge point is preferably a point where the time required for the vehicle to arrive at the merge point and the time required for the ambulance to arrive at the merge point are equal and shortest. The junction point is preferably the point where the total time of the time required for the passenger to join the ambulance and the time required from the junction point to the hospital is the shortest. However, when the vehicle is not in a state where it can move from the current position, the joining point may be selected as the current position of the vehicle.

Or, even if the diagnosis result information of the occupant by the doctor is “high urgency”, if the current position information of the vehicle is close to the hospital, the junction point selection unit 22 does not select the junction point, It is good also as having you move by a vehicle.

Furthermore, when the vehicle or ambulance arrives at the merge point first, the merge point selection unit 22 may select a new merge point between the vehicle and the ambulance again. The case of arriving first includes the case where the vehicle or ambulance arrives first at the meeting point and the case where the vehicle or ambulance is predicted to arrive first at the meeting point. In the present embodiment, a case where a vehicle or an ambulance arrives first at a meeting point will be described. For example, when the ambulance arrives at the merge point first, the merge point selection unit 22 may select an intermediate point on the route from the current position of the vehicle to the merge point as a new merge point. Alternatively, for example, when the ambulance arrives at the merge point first, the merge point selection unit 22 may select an intermediate point on the route directly from the current position of the vehicle to the hospital as a new merge point. The new joining point is preferably the point where the total time of the time required for the passenger to join the ambulance and the time taken from the new joining point to the hospital is the shortest.

The transmission unit 23 transmits information on the junction point selected by the junction point selection unit 22 to the transport support device 10 and the ambulance.

Next, information processing in the transport support system 1 will be described with reference to FIG. FIG. 3 is a sequence diagram showing the flow of processing in the transport support system according to the first embodiment. Here, the hospital is the emergency hospital nearest to the current location of the vehicle. A conveyance support device 10 is mounted on the vehicle, and a meeting point selection device 20 is disposed in the hospital.

In the conveyance support apparatus 10, the vehicle position information acquisition unit 12 always acquires the current position information of the vehicle from the GPS receiver while the vehicle is operating (step S11).

In the transport support apparatus 10, the detection data acquisition unit 11 constantly acquires detection data that is biometric information of a vehicle occupant from the detection unit 100 during a period in which the vehicle is operating (step S12).

In the conveyance support apparatus 10, the determination unit 13 determines whether the occupant's body is estimated to be in an abnormal state based on the detection data acquired by the detection data acquisition unit 11 at regular intervals or every predetermined time (step S13). .

The step S13 will be described in detail with reference to FIG. FIG. 4 is a flowchart showing the flow of processing in the transport support apparatus according to the first embodiment.

The conveyance support apparatus 10 determines whether the occupant's body is estimated to be in an abnormal state based on the detection data acquired by the detection data acquisition unit 11 by the determination unit 13 (step S131). Then, when the conveyance support apparatus 10 determines that the occupant's body is estimated to be in an abnormal state by the determination unit 13 (Yes in step S131), the conveyance support device 10 proceeds to step S132. If the determination unit 13 determines that the occupant's body is not estimated to be abnormal (No in step S131), the conveyance support apparatus 10 ends the process. When the occupant's body is in an abnormal state (Yes in step S131), the conveyance support apparatus 10 stops the vehicle at a safe place by the automatic operation control unit 18 (step S132). The conveyance support apparatus 10 outputs the determination result to the confluence point selection apparatus 20 of the nearest emergency hospital together with the abnormality information that is the detection data by the transmission unit 15 (step S133).

Returning to FIG. 3, in the conveyance support apparatus 10, the transmission unit 15 transmits the current position information and the abnormality information to the meeting point selection apparatus 20.

In the junction point selection device 20, the reception unit 21 receives abnormality information from the conveyance support device 10. The receiving unit 21 notifies the doctor of the received abnormality information.

The doctor confirms the notified abnormality information and diagnoses the occupant's symptoms. When a doctor diagnoses that an occupant's symptom has a high degree of urgency, the person in charge of the hospital determines whether or not the occupant can accept the emergency.

If it is determined that the hospital cannot accept the information, the joining point selecting device 20 notifies the vehicle that the data cannot be received by the transmitter 23. When the vehicle receives a result indicating that the vehicle cannot be received from the merge point selection device 20 of the hospital, the vehicle is similar to the merge point selection device 20 of other emergency hospitals until a hospital that can obtain a result indicating that the vehicle is acceptable is found. Execute the process.

When it is determined that the person in charge of the hospital can accept the meeting, the joining point selecting device 20 selects the joining point (step S21).

The step S21 will be described in detail with reference to FIG. FIG. 5 is a flowchart showing a flow of processing in the joining point selection device according to the first embodiment.

The joining point selecting device 20 acquires the current position information of the vehicle by the joining point selecting unit 22 (step S211). And the junction point selection apparatus 20 judges whether the emergency degree is considered high by the doctor by the junction point selection part 22 (step S212). If the doctor determines that the urgency level is high by the doctor (Yes in step S212), the joining point selecting device 20 proceeds to step S213. If the merging point selection unit 22 does not determine that the urgency level is high by the doctor (No in step S212), the merging point selection device 20 proceeds to step S214. When the degree of urgency is high (Yes in Step S212), the joining point selecting device 20 determines whether the vehicle is close to the location of the hospital from the current position information of the vehicle by the joining point selecting unit 22 (Step S213). . For example, suppose that it is close to the location of the hospital within 30 minutes. When the joining point selecting unit 20 determines that the vehicle is close to the location of the hospital by the joining point selecting unit 22 (Yes in Step S213), the joining point selecting unit 20 proceeds to Step S214. When the joining point selection unit 22 determines that the vehicle is not near the location of the hospital (No in step S213), the joining point selection device 20 proceeds to step S215. When the degree of urgency is low (No in step S212), or when the vehicle is close to the location of the hospital (Yes in step S213), the joining point selecting device 20 causes the joining point selecting unit 22 to drive the vehicle to the hospital. Thus, the self-propelled information with the hospital as the destination is transmitted to the conveyance support apparatus 10 (step S214). When the vehicle is not close to the location of the hospital (No in step S213), the merging point selecting device 20 selects a merging point by the merging point selecting unit 22 (step S215). And the junction point selection apparatus 20 transmits the junction point information of the selected junction point by the junction point selection part 22 to the conveyance assistance apparatus 10 (step S216).

Returning to FIG. 3, in the conveyance support apparatus 10, the receiving unit 16 receives the merge point information from the merge point selection apparatus 20.

In the transport support apparatus 10, the route search unit 17 searches for a route to the junction and starts automatic travel (step S14).

The step S14 will be described in detail with reference to FIG. FIG. 6 is a flowchart showing the flow of processing in the transport support apparatus according to the first embodiment.

The transport support apparatus 10 acquires the junction point information by the route search unit 17 (step S141). And the conveyance assistance apparatus 10 searches the route to a junction with the route search part 17 (step S142). And the conveyance assistance apparatus 10 outputs the control signal which makes a vehicle drive automatically to the destination by the automatic driving control part 18 according to the searched route information to a travel control part (step S143). The conveyance support device 10 transmits the current position information to the joining point selection device 20.

Returning to FIG. 3, when the vehicle starts automatic driving up to the joining point, the conveyance support device 10 transmits the current position information of the vehicle to the joining point selection device 20 at all times or every predetermined time. In addition, the current position information of the ambulance is transmitted from the junction point selection device 20 to the conveyance support device 10 at all times or every predetermined time.

In the merge point selection device 20, the merge point selection unit 22 reselects the merge point according to the situation (step S22).

The step S22 will be described in detail with reference to FIG. FIG. 7 is a flowchart showing the flow of processing in the joining point selection device according to the first embodiment.

The joining point selecting device 20 acquires the current position information of the vehicle by the joining point selecting unit 22 (step S221). The joining point selecting device 20 acquires the current position information of the ambulance by the joining point selecting unit 22 (step S222). And the junction point selection apparatus 20 judges whether the vehicle or the ambulance arrived at the junction point first by the junction point selection part 22 (step S223). When the joining point selecting unit 22 determines that the vehicle or the ambulance has arrived at the joining point first (Yes in Step S223), the joining point selecting device 20 proceeds to Step S224. If the joining point selecting unit 22 determines that the vehicle or the ambulance has not arrived at the joining point first (No in step S223), the joining point selecting device 20 ends the process. When the vehicle or the ambulance arrives at the merge point first (Yes in step S223), the merge point selection device 20 uses the merge point selection unit 22 to obtain information from the current position information of the delayed ambulance or vehicle to the merge point. It is determined whether the estimated arrival time is a time that is a threshold value or more after the current time (step S224). For example, the threshold is about 10 minutes. When the joining point selecting unit 22 determines that the scheduled arrival time at the joining point is a time that is more than the threshold from the current time (Yes in step S224), the joining point selecting unit 22 proceeds to step S225. The joining point selecting device 20 ends the process when the joining point selecting unit 22 determines that the estimated arrival time at the joining point is not a time beyond the threshold from the current time (No in step S224). In this case, the ambulance or vehicle that arrives first at the current junction waits for the arrival of the delayed vehicle or ambulance. When the estimated arrival time at the later merge point is a time that is a threshold value or more (Yes in step S224), the merge point selection device 20 reselects the merge point by the merge point selection unit 22 (step S224). S225). And the junction point selection apparatus 20 transmits the junction point information of the junction point reset by the junction point selection part 22 to the conveyance assistance apparatus 10 (step S226).

Referring back to FIG. 3, in the conveyance support device 10, the receiving unit 16 receives the merge point information reset from the merge point selection device 20.

In the transport support apparatus 10, the route search unit 17 searches for a route to the re-established junction and starts automatic travel (step S15).

In this way, when the occupant's body is in an abnormal state, the transport support system 1 selects a route to the junction between the ambulance and the vehicle, and causes the vehicle to travel to the junction with the ambulance.

As described above, according to the present embodiment, when the occupant's body becomes abnormal, the route to the junction is selected and the vehicle is automatically driven to the junction with the ambulance. Thereby, this embodiment can reduce a time loss compared with the case where it waits for the arrival of an ambulance in the present position of a vehicle. Thus, according to the present embodiment, emergency response can be improved.

In this embodiment, when a vehicle or an ambulance arrives at the merge point first, the merge point is reset. Although an ambulance can travel urgently, the vehicle cannot travel urgently, so there is a high possibility that the ambulance will arrive at the junction. Even in such a case, this embodiment can further reduce a time loss. In addition, this embodiment can further improve emergency response.

[Second Embodiment]

In the following description, the same components as those in the conveyance support system 1 are denoted by the same reference numerals or corresponding reference numerals, and detailed description thereof is omitted. The conveyance support system 1 according to the present embodiment is different from the conveyance support system 1 according to the first embodiment in that the joining point selection device 20 is arranged in a fire department (emergency conveyance support facility).

Next, information processing in the transport support system 1 will be described with reference to FIG. The processing in the conveyance support apparatus 10 is the same as that in the first embodiment.

In the meeting point selection device 20 arranged in the fire department, the receiving unit 21 receives abnormality information from the transport support device 10. The receiving unit 21 notifies the doctor of the hospital of the received abnormality information.

In the fire department, the person in charge or paramedic determines the urgency level, in other words, the necessity of emergency transport, based on the received abnormality information.

The doctor confirms the abnormality information notified from the meeting point selection device 20 and diagnoses the occupant's symptoms. When a doctor diagnoses that an occupant's symptom has a high degree of urgency, the person in charge of the hospital determines whether or not the occupant can accept the emergency. The hospital answers (contacts) the acceptance to the fire department.

If the hospital is acceptable, in the merging point selection device 20 of the fire department, the merging point selecting unit 22 selects a merging point (step S31). The meeting point selection device 20 of the fire department transmits the meeting point information to the conveyance support device 10.

As described above, the junction point selecting device 20 can be arranged at a fire station or the like having authority to select an emergency transport destination or issue a dispatch command for an ambulance. Thereby, since a fire department can select a crew member's transportation destination, this embodiment can improve emergency response more.

The components of the illustrated conveyance support system 1 are functionally conceptual and may not necessarily be physically configured as illustrated. That is, the specific form of each device is not limited to the one shown in the figure, and all or a part of them is functionally or physically distributed or integrated in arbitrary units according to the processing load or usage status of each device. May be.

The configuration of the transport support system 1 is realized by, for example, a program loaded in a memory as software. The above embodiment has been described as a functional block realized by cooperation of these hardware or software. That is, these functional blocks can be realized in various forms by hardware only, software only, or a combination thereof.

The constituent elements described above include those that can be easily assumed by those skilled in the art and those that are substantially the same. Furthermore, the structures described above can be appropriately combined. In addition, various omissions, substitutions, or changes in the configuration can be made without departing from the scope of the present invention.

In the above description, the case where the ambulance is an ambulance has been described. However, the present invention can also be applied to an emergency life-saving helicopter. In the case of a helicopter for emergency lifesaving, the merging point selection unit 22 selects the nearest heliport as a merging point. In addition, when the nearest heliport is in a remote location, the vehicle may first be transported to the heliport by an ambulance after joining the ambulance. In this case, the meeting point is an intermediate point between the location of the heliport and the current position of the vehicle, for example, a parking lot such as a public facility, a park, a shoulder of a road where parking can be stopped, and an ambulance safely. It is preferable to select a movable point. The junction point is preferably the point where the total time of the time required for the occupant to join the ambulance and the time required to arrive at the heliport from the junction point is the shortest.

In the above description, the determination unit 13 sets the state in which emergency transport is required as an abnormal state, but is not limited thereto. For example, when an occupant has a chronic illness, an abnormal value of detection data that requires emergency transport according to the chronic illness is stored. The determination unit 13 may determine that the detection data is in an abnormal state when the detected data exceeds a stored threshold value. Thereby, it is possible to more appropriately take an emergency response when an abnormal state due to the illness of the occupant occurs.

In the above description, the vehicle is described as being a vehicle capable of automatic driving, but is not limited thereto. For example, when an occupant other than the driver enters an abnormal state, or when an occupant other than the driver can drive even when the driver enters an abnormal state, the occupant follows the route searched by the route search unit 17. You may drive a vehicle and move to a junction.
