This is characterized in that the person is notified that the person is in an abnormal state.

  First, the configuration of the driver abnormality notification device according to the first embodiment will be described.

  FIG. 1 is a diagram illustrating an example of a configuration of a driver abnormality notification device 1 according to the first embodiment. As shown in FIG. 1, the driver abnormality notification device 1 according to the first embodiment detects a driver's abnormal state, and a control unit 2 that controls each unit provided in the driver abnormality notification device 1. The abnormal state detection unit 3, the communication control unit 4 that communicates with the communication terminals 10 to 13, the Bluetooth communication unit 5 that communicates with the communication terminals 11 to 13 by Bluetooth communication, and the notification destination of the abnormal state of the driver A storage unit 6 for storing addresses of the communication terminals 11 to 13, a door opening / closing detection unit 7 for detecting opening / closing of a vehicle door, a GUI unit 8 electrically connected to the touch panel 14 and the liquid crystal monitor 15, and an H An / F (Hands Free) microphone 16 and an H / F control unit 9 electrically connected to the H / F speaker 17 are provided. In the first embodiment, the communication terminal 10 represents a communication terminal possessed by the driver, and the communication terminals 11 to 13 represent communication terminals possessed by passengers in the vehicle.

  The control unit 2 includes an abnormal state detection unit for the communication terminal detection unit 21 that detects the communication terminals 11 to 13 carried by a passenger of the vehicle and the communication terminals 11 to 13 that are detected by the communication terminal detection unit 21. And a notification unit 22 for notifying the abnormal state detected in 3.

  The communication control unit 4 is logically connected to a communication terminal 10 possessed by the driver (carried in the vehicle). Here, the logical connection means that they are connected by some communication method. For example, in the first embodiment, the communication control unit 4 and the communication terminal 10 are connected via a mobile phone network.

  The Bluetooth communication unit 5 is physically connected to the communication terminals 11 to 13. Here, the physical connection refers to a connection using a specific communication method. For example, in the first embodiment, the Bluetooth communication unit 5 and the communication terminals 11 to 13 are connected by Bluetooth communication. That is, the communication terminals 11 to 13 possessed by the passenger have a Bluetooth function.

  The abnormal state detection unit 3 detects an abnormal state such as a driver's drowsiness or sudden physical abnormality (including psychosomatic abnormality). As a detection method, for example, a driver's face image is captured by image processing, and an abnormal state is detected based on a blink pattern of the captured face image. A physiological sensor is attached to the driver. There is a contact type direct method for detecting the abnormal state of the driver by performing the above, or an indirect method for detecting the abnormal state of the driver from the running state of the vehicle (for example, meandering). Any method may be used as long as it detects a person's abnormal state.

  FIG. 2 is a diagram illustrating an example in which the driver abnormality notification device 1 is arranged in a vehicle.

  As shown in FIG. 2, the driver brings the communication terminal 10 and the passenger brings the communication terminals 11 to 13 into the vehicle. Further, the driver abnormality notification device 1 is arranged on the front side in the vehicle.

  FIG. 3 is a diagram illustrating an example of a table indicating addresses of communication terminals that are notification destinations of the driver's abnormal state. FIG. 3 shows a case where a communication terminal possessed by a plurality of passengers is a notification destination.

  As shown in FIG. 3, a BD (Bluetooth Device) address that is a unique ID assigned to a communication terminal, a telephone number of the communication terminal, and a communication as an address of a communication terminal that is a notification destination of an abnormal state of the driver The mail address of the terminal is associated. And it is memorize | stored in the memory | storage part 6 in an order from a communication terminal with a high priority as a notification destination (priority 1 is the highest, and the priority N is the lowest). Thus, the address of each communication terminal is stored (registered) in advance in the storage unit 6 as a table. For example, in the first embodiment, the addresses of the communication terminals 11 to 13 are registered in the table of the storage unit 6.

  Next, the operation of the driver abnormality notification device according to the first embodiment will be described.

  FIG. 4 is a flowchart illustrating an example of an operation for notifying the driver of an abnormal state according to the first embodiment.

  In step S401, the control unit 2 determines whether or not the abnormal state detection unit 3 has detected that the driver is in an abnormal state. When it is detected that the driver is in an abnormal state, the process proceeds to step S402, and when it is not detected that the driver is in an abnormal state, the process is terminated.

  In step S402, the notification unit 22 notifies the notification destination communication terminal that the driver is in an abnormal state. At this time, the communication terminal as the notification destination is a communication terminal stored in advance in the storage unit 6, and the communication terminal is detected by the communication terminal detection unit 21. Further, the notification to the communication terminal of the notification destination is performed by Bluetooth communication by the Bluetooth communication unit 5 or by voice call or mail using the mobile phone network by the communication control unit 4 (abnormal using a predetermined communication method inside the vehicle). Notify the status.) That is, notification is performed using any of the addresses (BD address, telephone number, mail address) shown in FIG. After notification, the process is terminated.

  FIG. 5 is a flowchart showing an example of an operation of selecting a notification destination communication terminal according to the first embodiment, and selects a notification destination communication terminal present in the vehicle. The operation shown in FIG. 5 is performed by the control unit 2 controlling the communication control unit 4 and the Bluetooth communication unit 5. The determination process is performed by the control unit 2.

  In step S501, the control unit 2 determines whether the door opening / closing detection unit 7 detects the opening / closing of the vehicle door. If the opening / closing of the door is detected, the process proceeds to step S502. If the opening / closing of the door is not detected, the process ends.

  In step S502, the selection of the communication terminal selected as the notification destination is canceled. That is, when the door of the vehicle is opened or closed, no communication terminal is once set as the notification destination. This is because when the door of the vehicle is opened and closed, passengers get on and off, and the communication terminal selected as the notification destination may have moved out of the vehicle.

  In step S503, the communication terminal detection unit 21 searches for the communication terminals 11 to 13 existing in the vehicle by using the inquiry function of the Bluetooth communication unit 5 (a function for searching whether or not a Bluetooth device exists in the area). Search).

  In step S504, it is determined whether there is a communication terminal detected by the search in step S503. If there is a detected communication terminal, the process proceeds to step S505. If there is no detected communication terminal, the process ends.

  In step S505, the BD address of the communication terminal detected by the communication terminal detection unit 21 is collated with the BD address of the communication terminal registered in advance in the table (see FIG. 3) stored in the storage unit 6.

  In step S506, it is determined whether or not the BD addresses match as a result of the collation in step S505. If the BD addresses match, the process proceeds to step S508. If the BD addresses do not match, the process proceeds to step S507.

  In step S507, it is determined whether or not collation for all communication terminals detected by the communication terminal detection unit 21 has been completed. If the verification for all communication terminals is completed, the process is terminated. If the verification for all communication terminals is not completed, the process proceeds to step S505.

  In step S508, it is determined whether or not a communication terminal as a notification destination has already been selected. If it has been selected, the process proceeds to step S509, and if it has not been selected, the process proceeds to step S510.

  In step S509, it is determined whether or not the communication terminal having the same BD address in step S506 has a higher priority than the selected communication terminal. If the priority is high, the process proceeds to step S510. If the priority is not high (the priority is low), the process proceeds to step S507.

  In step S510, the communication terminal having the same BD address in step S506 is selected as a notification destination. Thereafter, the process proceeds to step S507.

  By performing the above processing, a communication terminal as a notification destination can be selected (detected) based on the inquiry function of Bluetooth communication. If a plurality of communication terminals are detected in step S504, the communication terminal with the highest priority can be selected as the notification destination. According to the inquiry function of the Bluetooth communication, a plurality of communication terminals having a Bluetooth function existing in the vehicle are simultaneously detected. Therefore, in the first embodiment, among the communication terminals detected by the processing of the inquiry function, a communication terminal registered in advance in the storage unit 6 and having a high priority is selected as the notification destination. That is, the notification unit 22 gives priority to a communication terminal having a high priority (priority order) among communication terminals stored in the storage unit 6 and notifies the notification.

  From the above, according to the first embodiment, when the driver is in an abnormal state, the communication terminal possessed by the passenger present in the vehicle is detected by Bluetooth communication, and the detected communication terminal is detected. The driver is in an abnormal state. Therefore, a passenger in the vehicle can promptly and safely wake up the driver. Further, by detecting the communication terminal when the door is opened and closed, the power required for detecting the communication terminal can be saved.

  In the first embodiment, when there are a plurality of communication terminals in the vehicle, the abnormal state of the driver is notified to the communication terminal having a high priority. However, the present invention is not limited to this and exists in the vehicle. You may make it notify abnormal state with respect to all the communication terminals.

It is characterized by doing. Other configurations are the same as those in the first embodiment, and thus description thereof is omitted here.

  FIG. 6 is a flowchart illustrating an example of an operation of selecting a notification destination communication terminal according to the second embodiment.

  In step S <b> 601, the control unit 2 determines whether the door opening / closing detection unit 7 has detected opening / closing of a vehicle door. If door opening / closing is detected, the process proceeds to step S602. If door opening / closing is not detected, the process ends. Note that the processing in step S601 is the same as the processing in step S501 in FIG.

  In step S602, the selection of the communication terminal selected as the notification destination is canceled. Note that the process of step S602 is the same as the process of step S502 of FIG.

  In step S <b> 603, the communication terminal detection unit 21 uses the Bluetooth communication unit 5 to link the communication terminals registered in the table of the storage unit 6 in order of priority (processing related to page (calling)). To implement. That is, a connection request is made to a specific communication terminal.

  In step S604, it is determined whether or not the link connection with the communication terminal that has requested connection is successful. If the link connection is successful, the process proceeds to step S606. If the link connection is not successful, the process proceeds to step S605.

  In step S605, it is determined whether or not link connection has been established for all registered communication terminals. If the link connection to all communication terminals is completed, the process is terminated. If the link connection to all communication terminals is not completed, the process proceeds to step S603.

  In step S606, the communication terminal that has succeeded in the Link connection is selected as a notification destination communication terminal. Thereafter, the process ends.

  From the above, according to the second embodiment, a communication terminal possessed by a passenger present in the vehicle is detected by link connection of Bluetooth communication, and the driver is in an abnormal state with respect to the detected communication terminal. Notify that there is. Therefore, a passenger in the vehicle can promptly and safely wake up the driver. In addition, when a plurality of communication terminals are registered, link connection is performed in order from the communication terminal with the highest priority, and communication terminals that have succeeded in link connection are used as notification destinations. Therefore, the processing is simpler than that of the first embodiment. Can detect the communication terminal.

  When a link connection is made to a communication terminal having a Bluetooth function that does not exist in the area (in the present embodiment, in the vehicle), it takes time to detect the failure, and the communication terminal to be notified Since it is necessary to perform link connection one by one, it may take longer to detect a communication terminal than in the first embodiment. Therefore, in the second embodiment, by performing link connection in descending order of priority, if the link connection is successful, the successful communication terminal is used as the notification destination, so the number of times of link connection is reduced.

<Modification>
In the first to fourth embodiments, the abnormal state detection unit 3 detects a snooze or a sudden physical abnormality as an abnormal state of the driver. However, the present invention is not limited to this. May be detected and notified to the passenger.

  In Embodiments 1 to 4, the communication terminal possessed by the passenger is not limited to a mobile phone or a smartphone, but may be a dedicated mobile terminal that performs short-range communication with the driver abnormality notification device 1.

  In the first to fourth embodiments, when there is no communication terminal in the vehicle (the communication terminal detection unit 21 cannot detect the communication terminal), the driver's abnormal state is outside the vehicle (outside the vehicle). May be notified (notified) to a communication terminal or a help call center. Here, the help call center means a public institution such as a police station, a police box, a fire station, or a hospital. In addition, when notifying the driver's abnormal state outside the vehicle, notification is made using a predetermined communication network such as a telephone line network outside the vehicle.

  In Embodiments 1 to 4, the notification unit 22 notifies the driver of an abnormal state to the communication terminal possessed by the passenger via the emergency call system that exists outside the vehicle. Good. Here, the emergency call system means a public institution such as a police station, police box, fire station, hospital, etc., similar to the above-mentioned help call center.

  In the first and second embodiments, the communication terminal is detected when the door is opened and closed. However, when the abnormal state detection unit 3 detects the abnormal state of the driver, the communication terminal is detected. May be.

  In the first to fourth embodiments, when the communication terminal detection unit 21 detects a communication terminal, the storage unit distinguishes whether the communication terminal is owned by the driver or the communication terminal owned by the passenger. Although it detected using the passenger's address previously registered in the table memorize | stored in 6, the following 6 are mentioned as another method, for example. Note that the present invention is not limited to the following, and the communication terminal may be detected by any method as long as the communication terminal possessed by the driver can be distinguished from the communication terminal possessed by the passenger.

  (1) The address of the communication terminal possessed by the driver is stored in advance and used for collation with the communication terminal detected by the communication terminal detection unit 21. That is, when the detected address of the communication terminal matches the address of the communication terminal possessed by the driver, the detected communication terminal is not selected as the notification destination communication terminal.

  (2) When a communication terminal is detected, a message indicating whether or not the driver is a driver is sent to the detected communication terminal, and a response is received by the operation of the user who owns the detected communication terminal. If there is no response, you may consider yourself a passenger. Alternatively, if there is no response, the driver may be considered.

  (3) A communication terminal installed in a cradle for installing a communication terminal for a driver is regarded as a communication terminal possessed by the driver.

  (4) The communication terminal is distinguished and detected based on the radio wave intensity. For example, in the case of the first embodiment, when the antenna of the Bluetooth communication unit 5 of the driver abnormality notification device 1 is installed near the driver using the inquiry function of the Bluetooth communication, the radio wave intensity is strongest. It can be assumed that the driver has the communication terminal.

  (5) By touching (contacting) the communication terminal with a FeliCa input terminal or the like installed in the vicinity of the passenger seat, the user is made to recognize that the communication terminal is possessed by the passenger.

  (6) Sound or light is output from the detected communication terminal, the sound or light is input to a microphone or camera installed in the vehicle, and the position of the communication terminal is specified by acoustic processing or image processing. When there are a plurality of communication terminals, the position of each communication terminal can be specified by sequentially outputting the communication terminals.

  In addition, the notification of the abnormal state by the notification unit 22 is not limited to voice and mail, but may be any function as long as the communication terminal has a function such as vibration or image. At this time, notification may be performed using one function of the communication terminal, or notification may be performed by combining a plurality of functions.

  Moreover, in Embodiment 1-4, the notification part 22 is the 1st method with respect to the communication terminal which a passenger carries as a method of notifying a driver | operator's abnormal state with respect to the communication terminal which a passenger has. After notification (for example, ringing tone (pseudo sound)), if there is no passenger reaction to the notification, notification (for example, ringing tone + vibration (vibration)) may be made by the second method. Good.

  In the first to fourth embodiments, the communication unit 22 may change the notification method and message content for the communication terminal according to the type of the abnormal state of the driver detected by the abnormal state detection unit 3. .

  Moreover, the communication terminal detection part 21 may detect the communication terminal in a vehicle using a some communication system.
