  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the drawings. FIG. 1 is a configuration diagram illustrating a driver abnormal state detection system including a driver abnormal state detection device according to the present embodiment. As shown in FIG. 1, the driver abnormal state detection system 1 contacts a predetermined contact when a physical condition change (abnormal state) of a driver such as an elderly person is detected (notification to a family, arrangement of an ambulance, etc.) ), And includes a mobile device 10, a driver abnormal state detection device 20, and a center 30.

The portable device 10 is an external device carried by a driver, and corresponds to a mobile phone, a portable music player, or the like. The portable device 10 has a function of wirelessly connecting to the driver abnormal state detection device 20 by Bluetooth (registered trademark), WiFi (registered trademark), or the like.

  The driver abnormal state detection device 20 is an in-vehicle device mounted on the vehicle, and detects whether the driver is in an abnormal state. The driver abnormal state detection device 20 includes a vehicle state detection unit (vehicle state detection unit) 21, an operation detection unit (operation detection unit) 22, a wireless communication connection unit 23, and a portable device management unit (communication state detection unit). ) 24, an abnormal state detection unit (abnormal state detection unit) 25, and a communication unit (notification unit) 26.

  The vehicle state detection unit 21 detects the state of the vehicle on which the driver gets on, and in this embodiment, the engine is operating or stopped, or the vehicle is running or stopped. It detects whether the door is open or closed, and how long it has been open if the door is open. The vehicle state detection unit 21 is connected to an engine speed sensor, a vehicle speed sensor, and a door opening / closing sensor, and is configured to detect the vehicle state based on signals from these sensors.

  The operation detection unit 22 detects an operation on an in-vehicle device mounted in the vehicle, and detects an operation on the driver abnormal state detection device 20 in the present embodiment. In addition, the operation detection part 22 may detect operation with respect to other in-vehicle devices, such as not only the driver abnormal condition detection device 20 but a navigation device and an audio device mounted in the vehicle. When detecting an operation on a navigation device, an audio device, or the like, the driver abnormal state detection device 20 and these in-vehicle devices are connected by, for example, a signal line, and information operated by the in-vehicle device is transmitted to the operation detection unit 22. Will be.

The wireless communication connection unit 23 is for wireless communication connection with the mobile device 10. The wireless communication connection unit 23 is connected to the mobile device 1 by Bluetooth (registered trademark) or WiFi (registered trademark).
Wireless communication connection with 0.

The portable device management unit 24 detects a communication state between the portable device 10 that can be brought into the vehicle and the in-vehicle device. In this embodiment, the communication state between the portable device 10 and the driver abnormal state detection device 20 is detected. It is to detect. The mobile device management unit 24 stores information on the mobile device 10 to be connected by wireless communication. When the mobile device 10 storing the information approaches the vicinity of the vehicle, the mobile device management unit 24 makes a wireless communication connection to the wireless communication connection unit 23. This causes the wireless communication connection unit 23 to establish a wireless communication connection with the portable device 10. Note that the portable device management unit 24 is not limited to the case where the wireless communication connection is made via the wireless communication connection unit 23, but an instruction to establish a wireless communication connection with other in-vehicle devices such as a navigation device and an audio device mounted in the vehicle. Then, the communication state with these in-vehicle devices may be detected. When wireless communication connection is made with a navigation device, an audio device, or the like, the driver abnormal state detection device 20 and these in-vehicle devices are connected by, for example, a signal line, and information on the communication state with the in-vehicle device is stored in the portable device management unit 24. Will be sent to. Furthermore, the portable device management unit 24 can detect a communication state with not only the driver but also the portable device 10 that the driver's family brings into the vehicle.

  The abnormal state detection unit 25 detects whether or not the driver is in an abnormal state based on detection results by the vehicle state detection unit 21, the operation detection unit 22, and the portable device management unit 24. In addition, when detecting that the driver is in an abnormal state, the abnormal state detection unit 25 transmits a signal to that effect to the communication unit 26, and the communication unit 26 notifies the driver that the driver is in an abnormal state. Transmit to the center 30.

  In addition, each part 21-26 of the said driver | operator abnormal state detection apparatus 20 can be comprised as each function of various communication antennas or CPU (Central Processing Unit).

  The center 30 is configured to be communicable with the driver abnormal state detection device 20, receives a notification that the driver is in an abnormal state from the driver abnormal state detection device 20, and re-checks whether the driver is in an abnormal state. It is for confirmation. The center 30 includes a communication unit (contact unit) 31, an abnormal state determination unit (abnormal state determination unit) 32, a map DB (database) 33, and an action history DB 34.

  The communication unit 31 communicates with the driver abnormal state detection device 20 and receives a notification that the driver is in an abnormal state. Further, the communication unit 31 has a function of making a notification to notify a predetermined contact address of an abnormal state. Here, the predetermined contact is a family mobile phone, a police station, or a fire department. If the communication unit 31 determines that the driver is in an abnormal state, the communication section 31 informs the family to that effect, Or arrange for an ambulance.

  The abnormal state determination unit 32 determines whether or not the driver is in an abnormal state again when the driver abnormal state detection device 20 notifies the driver of the abnormal state. The abnormal state determination unit 32 is configured to determine whether or not the driver is in an abnormal state based on the presence or absence of a passenger, vehicle position, past action history, confirmation to the driver, and the like.

  The map DB 33 stores map information including node information, link information, facility information, and place name information. Here, from the driver abnormal state detection device 20, vehicle position information is transmitted. For this reason, the abnormal state determination unit 32 can specify the position of the vehicle from the transmitted position information and the map information stored in the map DB 33, and when the vehicle is stopped, the vehicle is located at which facility. It is possible to identify whether it is located.

  The action history DB 34 stores the past actions of the driver, and in this embodiment, stores the date and day of the week when the abnormal state is notified from the driver abnormal state detection device 20.

  In addition, each part 31-34 of the center 30 can also be comprised as each function of various communication antennas or CPU (Central Processing Unit).

  Next, an outline of the operation of the driver abnormal state detection system 1 according to the present embodiment will be described. FIG. 2 is a flowchart showing an outline of the operation of the driver abnormal state detection system 1 according to the present embodiment.

  In using this system 1, first, as shown in FIG. 2, the mobile device 10 of the driver and family and the contact information of the family are registered in the center 30 (S1). Next, the portable device 10 wirelessly connected to the driver abnormal state detection device 20 is registered in the driver abnormal state detection device 20 (S2). Thereafter, the system 1 operates as follows.

  First, the driver abnormal state detection device 20 detects a vehicle state, an operation, and a communication state by the vehicle state detection unit 21, the operation detection unit 22, and the portable device management unit 24 (S3). And the abnormal condition detection part 25 detects whether a driver | operator is in an abnormal condition from the information detected in step S3 (S4).

  FIG. 3 is a diagram showing an abnormal state detection process in step S4. As shown in FIG. 3, when the engine is operating and the vehicle is running, the abnormal state detection unit 25 detects that the driver is not in an abnormal state regardless of other detection results.

  The abnormal state detection unit 25 is based on the assumption that the driver's portable device 10 is connected to the driver abnormal state detection device 20, and is predetermined when the engine is operating and the vehicle is stopped. When the door is open continuously for a period of time, it is detected that the driver is in an abnormal state. At this time, since the door is kept open for a predetermined time, there is a possibility that the driver is unable to move due to poor physical condition when the vehicle gets on and off.

  Further, the abnormal state detection unit 25 detects that the driver is in an abnormal state on the premise of the above, and in the above case, when an operation is not detected continuously for a specified time. At this time, since no operation is performed on the in-vehicle device, there is a possibility that poor physical condition occurs and the driver cannot move.

  Further, the abnormal state detection unit 25 assumes that the driver's portable device 10 is connected to the driver abnormal state detection device 20, and when the engine is stopped, the door is continuously opened for a predetermined time. The driver detects that the driver is in an abnormal state. At this time as well, as described above, since the door is kept open for a predetermined time, there is a possibility that the driver is unable to move due to poor physical condition when the vehicle gets on and off.

  In addition, the abnormal state detection unit 25 assumes that the driver's portable device 10 is connected to the driver abnormal state detection device 20, and the driver is in an abnormal state when the engine is stopped. Is detected. In this case, since no motion is detected even though the driver is near the vehicle, there is a possibility that the driver near the vehicle is in poor physical condition and cannot move.

  Reference is again made to FIG. In step S4, the abnormal state detection unit 25 detects the abnormal state of the driver as shown in FIG. Then, when the abnormal state detection unit 25 detects the driver's abnormal state, the communication unit 26 notifies the center 30 that the driver is in an abnormal state (S5). At this time, in the four cases where the abnormal state is detected, the communication unit 26 may transmit a different notification signal to notify where the driver is unable to move, and each may transmit the same notification signal. It may be transmitted to notify only that it is in an abnormal state.

  Thereafter, the abnormal state determination unit 32 of the center 30 determines whether the driver is in an abnormal state (S6). At this time, the abnormal state determination unit 32 determines whether the driver is in an abnormal state as follows.

First, the abnormal state determination unit 32 determines that the driver is not in an abnormal state when determining that there is a passenger in the vehicle that has been notified of the abnormal state. For example, when there is a passenger, even if an abnormal state occurs in the driver, it is expected that the passenger will be able to take care of the passenger. It is also possible to detect an abnormal state.

  In addition, the abnormal state determination unit 32 determines that the driver is not in an abnormal state when the vehicle that has been notified of the abnormal state is located at a predetermined location. This is because, for example, when the predetermined location is a car wash place, the possibility that the driver only performs the car wash near the vehicle is considered.

  In addition, when there is a notification of an abnormal state, the abnormal state determination unit 32 refers to a past determination result stored in the behavior history DB 34 and determines whether or not the driver is in an abnormal state. For example, it is possible to identify the day, time, and day of the week when the driver is likely to be in an abnormal state from past determination results, and to determine that there is a high possibility of an abnormal state in the vicinity.

  Furthermore, in the present embodiment, the center 30 transmits a confirmation command for confirming whether there is an abnormality to the driver abnormal state detection device 20 when there is a notification of the abnormal state. When the driver abnormal state detection device 20 receives the confirmation command, the driver presents information that prompts the vehicle occupant to confirm the abnormality and prompts the occupant to confirm that there is no abnormality. In this case, the center 30 is notified that there is no abnormality. Therefore, if there is a notification that there is no abnormality, it can be determined that there is no abnormal state. On the other hand, if there is no notification that there is no abnormality for a predetermined time, it is determined that the driver is in an abnormal state.

  As described above, the abnormal state detection unit 25 determines whether the driver is in an abnormal state. And when it judges that a driver | operator is in an abnormal state, the communication part 31 contacts a predetermined contact (S7). Thereby, it is possible to contact the family and arrange an ambulance.

  Next, the abnormal state detection method according to the present embodiment will be described. FIG. 4 is a flowchart showing the abnormal state detection method according to the present embodiment, and shows processing in the abnormal state detection apparatus 20.

  As shown in FIG. 4, first, the abnormal state detection unit 25 determines whether or not the vehicle state detection unit 21 detects that the engine is operating (S11). When it is detected that the engine is operating (S11: YES), the abnormal state detection unit 25 determines whether or not the vehicle state detection unit 21 detects that the vehicle is stopped (S12).

  When it is detected that the vehicle is not stopped (S12: NO), that is, when the vehicle is running, the processing shown in FIG. 4 ends. When the vehicle is running, for example, the technique disclosed in Patent Document 1 may be used to determine whether or not the driver is in an abnormal state, or the abnormal state may be detected using another technique. Also good.

  On the other hand, when it is detected that the vehicle is stopped (S12: YES), the abnormal state detection unit 25 determines whether or not the mobile device management unit 24 detects that the mobile device 10 is being connected ( S13).

  If it is detected that the mobile device 10 is not connected (S13: NO), it can be assumed that the driver is not nearby in the first place, and thus the process shown in FIG. 4 ends. When it is detected that the mobile device 10 is connected (S13: YES), the abnormal state detection unit 25 determines whether or not the vehicle state detection unit 21 detects that the door is continuously opened for a predetermined time. Judgment is made (S14).

  If it is detected that the door is opened continuously for a predetermined time (S14: YES), it is predicted that the portable device 10 is connected and the driver is nearby, and the engine is operating and the vehicle Since the door is opened continuously for a predetermined period of time despite the fact that the vehicle is stopped, the driver may be unable to move due to poor physical condition when getting on and off the vehicle. Therefore, the abnormal state detection unit 25 detects that the driver is in an abnormal state, and transmits a first notification signal to the center 30 through the communication unit 26 (S15). Thereafter, the process shown in FIG. 4 ends.

  On the other hand, if it is detected that the door has not been opened for a predetermined time (S14: NO), the abnormal state detection unit 25 has detected that the operation detection unit 22 has detected no operation for a specified time. Is determined (S16). If it is detected that there is no operation for a specified time (S16: YES), it is predicted that the portable device 10 is connected and the driver is nearby, and the engine is operating and the vehicle stops. However, since there is no operation for a specified time continuously, the driver may be unable to move due to poor physical condition in the vehicle. Therefore, the abnormal state detection unit 25 detects that the driver is in an abnormal state, and transmits a second notification signal to the center 30 through the communication unit 26 (S17). Thereafter, the process shown in FIG. 4 ends.

  In addition, when it is detected that an operation has been performed during the specified time (S16: NO), the driver's operation can be determined to be normal, so the abnormal state detection unit 25 does not determine that the driver is in an abnormal state. The process shown in 4 ends.

  By the way, when it is detected that the engine is not operating (S11: YES), that is, when the engine is stopped, the abnormal state detection unit 25 detects that the mobile device 10 is connected by the mobile device management unit 24. It is determined whether it has been done (S18).

  If it is detected that the mobile device 10 is not connected (S18: NO), it can be assumed that the driver is not nearby in the first place, and thus the process shown in FIG. 4 ends. When it is detected that the mobile device 10 is connected (S18: YES), the abnormal state detection unit 25 determines whether or not the vehicle state detection unit 21 detects that the door is continuously opened for a predetermined time. Judgment is made (S19).

  When it is detected that the door is opened continuously for a predetermined time (S19: YES), it is predicted that the mobile device 10 is connected and the driver is nearby, and the door is opened continuously for a predetermined time. Therefore, the driver may be unable to move due to poor physical condition when getting on and off the vehicle. Therefore, the abnormal state detection unit 25 detects that the driver is in an abnormal state, and transmits a third notification signal to the center 30 through the communication unit 26 (S20). Thereafter, the process shown in FIG. 4 ends.

  On the other hand, when it is detected that the door is not opened continuously for a predetermined time (S19: NO), it is predicted that the portable device 10 is connected and the driver is close, and this state continues for a long time. In this case, there is a possibility that the driver near the vehicle is in poor physical condition and the driver cannot move. Therefore, the abnormal state detection unit 25 detects that the driver is in an abnormal state, and transmits a fourth notification signal to the center 30 through the communication unit 26 (S21). Thereafter, the process shown in FIG. 4 ends.

  In the case of performing notification in the process of step S21, it is desirable to perform a determination process for confirming that the connection time of the mobile device 10 is a predetermined time or more. This is because it is possible to prevent the driver from being detected as being in an abnormal state simply by approaching the vehicle.

FIG. 5 is a flowchart showing the abnormal state detection method according to this embodiment.
The process in is shown.

  As shown in FIG. 5, first, the abnormal state determination unit 32 determines whether or not a notification indicating an abnormal state is received from the driver abnormal state detection device 20 (S31). If it is determined that there is no notification (S31: NO), the process shown in FIG. 5 ends.

  On the other hand, when it is determined that there is a notification (S31: YES), the abnormal state detection unit 32 determines whether there is a passenger (S32). Here, if the driver abnormal state detection device 20 determines that the plurality of portable devices 10 are connected by the portable device management unit 24, the type of the plurality of portable devices 10 (and Number) information. Therefore, the abnormal state detection unit 32 determines whether or not the family mobile device 10 is registered in advance based on this information, and determines whether or not there is a passenger.

  When it is determined that there is no passenger (S32: NO), the abnormal state detection unit 32 determines whether or not the vehicle is present at an abnormality detection exclusion point (a predetermined location such as a car wash place) ( S33). When it is determined that the vehicle is present at the abnormality detection exclusion point (S33: YES), for example, the possibility that the driver is just washing the vehicle near the vehicle is considered. Therefore, the abnormal state determination unit 32 determines that the driver is not in an abnormal state, and the process illustrated in FIG. 5 ends.

  On the other hand, when it is determined that the vehicle does not exist at the abnormality detection exclusion point (S33: NO), the abnormal state determination unit 32 determines whether or not the current notification should be excluded from the history of determination results regarding past abnormal states. (S34). For example, it is possible to specify a time when the driver is likely to be in an abnormal state from past determination results, and to determine that there is a high possibility of an abnormal state near that time. On the contrary, if it is out of the vicinity of the time, the possibility of not being in an abnormal state increases. Therefore, the abnormal state determination unit 32 determines that it should be excluded, for example, when it is out of the vicinity of the time (S34: YES), and the process illustrated in FIG. 5 ends.

  On the other hand, if it is determined that this notification should not be excluded (S34: NO), the abnormal state determination unit 32 determines that the driver is in an abnormal state, and the communication unit 31 contacts a predetermined contact ( S35). Then, the process shown in FIG.

  When it is determined that there is a passenger (S32: YES), the communication unit 31 contacts the passenger (S36). At this time, for example, the communication unit 31 communicates that the driver returns if the driver is not in an abnormal state. Thereafter, the abnormal state determination unit 32 determines whether or not there is a reply from the passenger (S37).

  When it is determined that there is a reply from the passenger (S37: YES), the abnormal state determination unit 32 determines that the driver is not in an abnormal state, and the process illustrated in FIG. 5 ends. On the other hand, when it is determined that there is no reply from the passenger (S37: NO), the abnormal state determination unit 32 determines that the driver is in an abnormal state, and the communication unit 31 contacts a predetermined contact (S35). ). Then, the process shown in FIG.

  In the process shown in FIG. 5, when it is determined “YES” in the process of step S <b> 32, the passenger is contacted (S <b> 36). However, the present invention is not limited to this. It may be determined that there is no abnormal state without contacting the person. When there is a passenger, even if an abnormal condition occurs in the driver, the passenger can be expected to be involved, and the abnormal condition detection unit 25 is erroneously abnormal due to a conversation with the passenger in the first place. This is because it is possible to detect the state.

Further, in the present embodiment, the center 30 may perform the following processing. For example, the communication unit 31 of the center 30 transmits a confirmation command for confirming whether or not there is an abnormality to the driver abnormal state detection device 20 when there is a notification of the abnormal state. When the driver abnormal state detection device 20 receives the confirmation command, the driver abnormal state detection device 20 presents information that prompts the vehicle occupant to confirm the abnormality and prompts the occupant to perform an operation indicating that there is no abnormality. If there is an operation to that effect, a notification that there is no abnormality is sent to the center 30, and if there is no operation, a notification that there is an abnormality to the center 30 is sent. In this case, not only when there is a passenger, but also when there is no passenger, the driver can be inquired whether it is in an abnormal state, and the detection accuracy of the abnormal state can be further improved. is there.

  In addition, when the confirmation command is transmitted, it is not possible to finally determine whether the driver is in an abnormal state (for example, if it is delicate whether or not to exclude from the past history), or abnormal state detection notification continues. It is desirable to perform when it is difficult to determine whether or not an abnormal state occurs. This is because the processing load can be reduced without sending a confirmation command when the state is clearly abnormal or when it is not clearly abnormal.

  In addition, in the process of FIG. 5, it is needless to say that the abnormal state determination unit 32 stores the information together with the date and time in the history DB 34 after determining whether or not there is an abnormal state. This is because it is possible to improve the determination accuracy based on the history after the next time.

  Thus, according to the driver abnormal state detection device 20 and the method according to the present embodiment, the driver is determined based on the detection result of the vehicle state, the operation on the in-vehicle device, and the communication state between the portable device 10 and the in-vehicle device. In order to detect whether or not the vehicle is in an abnormal state, for example, the driver's abnormal state can be detected from an operation on in-vehicle devices while the vehicle is stopped or a communication state of the mobile device 10. Therefore, it is possible to detect the abnormal state of the driver even when not driving.

  In addition, when it is detected that the engine is operating, the vehicle is stopped, the door is open continuously for a predetermined time, and the portable device 10 is detected as communicating with the in-vehicle device, The person is in an abnormal state. Here, since the mobile device 10 is communicating with the in-vehicle device, it is predicted that the driver is near, and the door is continuously opened for a predetermined time even though the engine is operating and the vehicle is stopped. When the vehicle is open, there is a possibility that the driver is unable to move due to poor physical condition when the vehicle gets on and off. Therefore, it is possible to detect the occurrence of an abnormal state when getting on and off while the vehicle is stopped.

  Further, it is detected that the engine is operating and the vehicle is stopped, the in-vehicle device is detected not to be operated continuously for a specified time, and the portable device 10 is detected to be in communication with the in-vehicle device. If it is, the driver is detected to be in an abnormal state. Here, since the mobile device 10 is communicating with the in-vehicle device, it is predicted that the driver is close, and the vehicle is continuously in the vehicle for a specified time despite the engine being operated and the vehicle being stopped. When the device is not operated, there is a possibility that poor physical condition occurs in the vehicle and the driver cannot move. Therefore, it is possible to detect the occurrence of an abnormal state in the vehicle while the vehicle is stopped.

  Further, when it is detected that the engine is stopped and the door is continuously open for a predetermined time, and it is detected that the mobile device 10 is communicating with the in-vehicle device, the driver is in an abnormal state. To detect. Here, since the mobile device 10 is communicating with the in-vehicle device, it is predicted that the driver is near, the engine is stopped, and the door is open continuously for a predetermined time. There is a possibility that the driver is unable to move due to poor physical condition when getting on and off the vehicle. Therefore, it is possible to detect the occurrence of an abnormal state when getting on and off while the engine is stopped.

Further, when it is detected that the engine is stopped and the portable device 10 is detected as communicating with the in-vehicle device, it is determined that the driver is in an abnormal state. Here, since the mobile device 10 is communicating with the in-vehicle device, it is predicted that the driver is close, and if this state continues for a long period of time, the driver near the vehicle has a poor physical condition. The driver may be stuck. Therefore, it is possible to determine the occurrence of an abnormal state before getting on or after getting off.

  Further, according to the driver abnormal state detection system 1 according to the present embodiment, when the center 30 is notified of the driver's abnormal state, the center 30 determines again whether the driver is in an abnormal state. If the driver's abnormal state is notified, the detection accuracy by this determination can be improved, and if the driver is determined to be in an abnormal state, the abnormal state is indicated to a predetermined contact. You can contact your family or arrange an ambulance to inform you.

  In addition, when it is determined that there is a passenger in the vehicle that has been notified of the abnormal state, the driver determines that the passenger is not in an abnormal state. It can be expected that an abnormal state is erroneously detected due to reasons such as being able to expect an intermediary by a person and having a conversation with a passenger in the first place. Therefore, by determining that the driver is not in an abnormal state when there is a passenger, it is possible to prevent unnecessary contact with a predetermined contact.

  In addition, when the vehicle that has been notified of the abnormal state is located at a predetermined location, the driver determines that the vehicle is not in an abnormal state. For example, when the predetermined location is a car wash, Consider the possibility of just washing the car near the vehicle. Therefore, by determining that the driver is not in an abnormal state in such a case, the detection accuracy of the abnormal state can be improved.

  In addition, when there is a notification of an abnormal state, the past determination result is referred to determine whether or not the driver is in an abnormal state. For example, the time when the driver is likely to be in an abnormal state based on the past determination result, etc. If it is near that time, it can be determined that there is a high possibility of an abnormal state. Therefore, the detection accuracy of the abnormal state can be improved.

  In addition, when there is a notification of an abnormal state, a confirmation command for confirming whether there is an abnormality is transmitted to the driver abnormal state detection device 20, and the driver abnormal state detection device 20 receives the confirmation command. Then, information presentation for prompting the vehicle occupant to confirm the abnormality is performed to prompt the occupant to perform an operation indicating no abnormality. For this reason, when there is no abnormality in the driver, an operation indicating that there is no abnormality is performed according to the information presentation. Since the center 30 is notified that there is no abnormality, the center 30 can determine that there is no abnormality when the center 30 is notified that there is no abnormality. The detection accuracy of the abnormal state can be improved.

  As described above, the present invention has been described based on the embodiments, but the present invention is not limited to the above-described embodiments, and modifications may be made without departing from the spirit of the present invention.
