  The present invention relates to a mobile communication device, a mobile communication terminal, and a boarding / alighting determination method for determining whether a pedestrian is on a vehicle.

  Intelligent transportation systems (Intelligent Transport Systems, hereinafter referred to as “ITS”) for the purpose of solving road traffic problems such as traffic accidents and traffic jams by networking people, roads and vehicles with information using information communication technology. ) Has been researched and developed. The form of wireless communication for automobiles in the field dealing with the safe driving support system in ITS can be broadly divided into road-to-vehicle communication and vehicle-to-vehicle (walking) communication. In the road-to-vehicle communication, the roadside machine and the vehicle communicate information, whereas in the vehicle-to-vehicle (walk) communication, the vehicle and the vehicle (or pedestrian) directly communicate information.

  Information transmitted from the roadside machine to the vehicle by road-to-vehicle communication includes intersection information and traffic signal information. The intersection information includes identification information for identifying the intersection, and the traffic signal information includes information such as identification information for identifying the traffic signal.

The moving body information includes information indicating a pedestrian's current position, moving speed, traveling direction, and the like (the same applies to inter-vehicle communication and inter-walk communication).

  Then, it is considered to prevent accidents by performing collision determination based on such vehicle moving body information and pedestrian moving body information and performing various controls when there is a possibility of collision (accident). It has been. On the other hand, when a mobile communication terminal such as a mobile phone possessed by a pedestrian transmits mobile body information as a pedestrian when the pedestrian is in the vehicle, an in-vehicle communication device mounted on a surrounding vehicle Makes a collision determination for a non-existent pedestrian.

  Therefore, in the driving support system disclosed in Patent Document 1, the portable terminal device determines whether or not the portable terminal device (the user (pedestrian) who owns the portable terminal device) is present in the vehicle. It is provided with a determination means, and when the current position of the vehicle and the current position of the pedestrian are the same, it is determined that the portable terminal is present in the vehicle, and transmission of the pedestrian's moving body information is stopped. Is disclosed.

  As a result, when the pedestrian is in the vehicle, the moving body information of the pedestrian is not transmitted, so that it is possible to prevent a safe driving control from being performed by determining a collision with a pedestrian having no surrounding vehicle. It is said.

[First embodiment]
A first embodiment of the mobile communication device of the present invention will be described with reference to FIG. FIG. 2 is a flowchart showing a flow of processing executed by the control unit 1 of the navigation device 20 of the present invention. In addition, the control part 1 of the navigation apparatus 20 shall perform the process shown below for every pedestrian (for every terminal ID of a mobile communication terminal).

  In step S <b> 101, the control unit 1 acquires the pedestrian moving body information received by the communication unit 8. The pedestrian moving body information includes information indicating the pedestrian ID (terminal ID of the mobile communication terminal), information indicating the current position (latitude, longitude) of the pedestrian, information indicating the traveling direction of the pedestrian, pedestrian The information indicating the moving speed of is included.

  In step S101, the control unit 1 acquires pedestrian moving body information. To be precise, the control unit 1 moves other moving bodies (such as other vehicles and pedestrians) received by the communication unit 8. Get body information.

  And when the moving body information of other acquired mobile bodies (another vehicle, a pedestrian, etc.) is a pedestrian's mobile body information, the control part 1 will progress to step S102 noting that it acquired the pedestrian's mobile body information. .

  The determination as to whether or not the acquired moving body information of other moving bodies (such as other vehicles and pedestrians) is the pedestrian moving body information indicates the movement type in the moving body information of the other moving bodies. In the case where information is included, it is possible to determine whether or not it is pedestrian moving body information based on the movement type (vehicle, pedestrian) (in the moving body information where the movement type is pedestrian). If there is a pedestrian's moving body information), the moving speed included in the moving body information (may be a moving speed based on the distance between the current position and the previous current position (transmitted from the same ID)) It is also possible to determine whether or not the pedestrian's moving body information is based on whether or not the speed is equal to or higher than a predetermined speed.

  Furthermore, it is also possible to determine whether or not the information is pedestrian moving body information from the current position. For example, based on the map information and the current position included in the moving body information of another moving body, if the current position is on the roadway, the moving body information of the vehicle is used, and if the current position is on the sidewalk, the moving body of the pedestrian It may be determined as information.

  Next, in step S102, the control unit 1 acquires the moving body information of the own vehicle. The moving body information of the own vehicle includes information indicating the current position of the own vehicle detected by the current position detection unit 4, and the current position detection unit 4 (when the navigation device 20 includes a movement direction detection unit, the movement direction detection unit Information indicating the traveling direction of the own vehicle detected by (good), information indicating the moving speed of the own vehicle detected by the speed detecting unit 5 and the like.

In this embodiment, the control unit 1 acquires pedestrian moving body information in step S101 and acquires the moving body information of the own vehicle in step S102. However, the control unit 1 acquires these information. The order may not be the order shown in the flowchart. For example, the order may be acquired at the same time first, or the moving body information of the own vehicle may be acquired first.
The timing at which the control unit 1 acquires the pedestrian's moving body information and the vehicle's moving body information is not limited to the timing. It may be acquired periodically or irregularly (for example, based on the transmission timing of another communication device (when the communication unit 8 receives it)). When acquiring information multiple times regularly or irregularly The newest information among the acquired information may be used.

  In step S103, the control unit 1 determines whether or not a pedestrian is in the vehicle. Whether or not the pedestrian is in the vehicle is determined based on the current position of the pedestrian, the current position of the vehicle, and the first predetermined range. FIG. 3 is a diagram illustrating an example of boarding determination based on the first predetermined range. As shown in FIG. 3, when the current position of the pedestrian is within a first predetermined range centered on the current position of the own vehicle, it is determined that the pedestrian is in the own vehicle.

  When the pedestrian is in the vehicle (Y in step S103), the process proceeds to step S104. When the pedestrian is not in the vehicle (N in step S103), the process returns to step S101.

  In step S104, the control unit 1 registers the terminal ID of a mobile communication terminal such as a mobile phone held by a pedestrian in the own vehicle in a storage area indicating that the mobile communication terminal is in the own vehicle ( Remember.

  That is, when the current position (the pedestrian's current position) included in the pedestrian's moving body information is within a first predetermined range centered on the current position of the car, the control unit 1 determines that the pedestrian's current position. In order to register (store) the terminal ID of the mobile communication terminal included in the mobile body information that includes the mobile communication terminal (the pedestrian holding the mobile communication terminal) having the registered (stored) terminal ID Is on board.

  The terminal ID may be registered (stored) in the RAM of the control unit 1, or a storage medium for registering (storing) the terminal ID may be provided separately.

  In step S105, the control unit 1 instructs the mobile communication terminal registered in step S104 to change the control of transmission of pedestrian moving body information.

  That is, the control unit 1 transmits information obtained by adding a terminal ID (registered (stored) terminal ID) as a destination to information instructing to change control of transmission of pedestrian moving body information via the communication unit 8. To send.

  The other communication device (mobile communication terminal) that has received the information transmitted via the communication unit 8 compares the destination terminal ID with its own terminal ID (the ID of the other communication device received), and the destination terminal. If the ID and the own terminal ID are the same, the control of the transmission of the pedestrian's mobile body information is changed based on the information for instructing to change the control of the transmission of the pedestrian's mobile body information.

  The change of transmission control in this step is to instruct the mobile communication terminal to transmit pedestrian mobile body information in a control state (special control state) different from the normal control state. The control unit 1 may specify a specific content of the special control state and instruct the change, or if the content of the special control state is set in advance in the mobile communication terminal, the control unit 1 is simply performed in the special control state. It may be an instruction.

  Here, the transmission of the pedestrian's mobile body information in the normal control state performed by the mobile communication terminal is information regarding a pedestrian that is predetermined to be transmitted from the mobile communication terminal to another communication device in the ITS communication. It is to transmit as pedestrian moving body information. Information on the pedestrian includes information indicating the pedestrian ID (terminal ID of the mobile communication terminal), information indicating the current position of the pedestrian, information indicating the direction of travel of the pedestrian, information indicating the moving speed of the pedestrian, etc. Is mentioned.

  On the other hand, transmission of pedestrian moving body information in the special control state is control different from the normal control state, for example, control for changing information on pedestrians transmitted as pedestrian moving body information, pedestrians Control for changing the transmission range of the mobile body information, control for stopping transmission of the mobile body information of the pedestrian, control combining these, and the like are conceivable.

  In this embodiment, when changing the information about the pedestrian transmitted as the moving body information of the pedestrian, for example, in the normal control state, the information about the pedestrian described above (terminal ID, current position, traveling direction, moving speed) ) Is transmitted as pedestrian moving body information, but only information indicating the terminal ID is transmitted as pedestrian moving body information in the special control state. That is, in the special control state, there is less information regarding the pedestrian transmitted as the pedestrian moving body information than in the normal control state. In addition, when the information indicating the movement type (pedestrian) is included in the pedestrian's moving body information, the movement type is changed to a vehicle or a pedestrian on board without reducing information on the pedestrian. It is good also as transmitting.

  In addition, when changing the transmission range of pedestrian moving body information, for example, the range for transmitting pedestrian moving body information is not limited in the normal control state, and is mounted on the vehicle in which the pedestrian is traveling in the special control state. The pedestrian's moving body information is transmitted to a narrow range that can be received by the in-vehicle communication device that is received (in the special control state, the transmission power is reduced compared to the normal control state). In addition, when stopping the transmission of pedestrian moving body information, the pedestrian moving body information is transmitted in the normal control state, and the pedestrian moving body information is not transmitted in the special control state. . Furthermore, it is possible to combine them into a special control state.

  In step S <b> 106, the control unit 1 changes the boarding determination threshold (first predetermined range) to the second predetermined range for the mobile communication terminal being boarded. Although both the first predetermined range and the second predetermined range are not limited, the second predetermined range is set to be wider than the first predetermined range.

  In step S107, the control unit 1 acquires pedestrian moving body information, and in step S108, the control unit 1 acquires moving body information of the host vehicle. In steps S107 to S108, it is clarified that the current position of the pedestrian and the current position of the own vehicle, which are the criteria for determination in step S109, are not acquired in steps S101 to S102 (that they are the latest). However, as described above, if the pedestrian's moving body information and the vehicle's moving body information are acquired regularly or irregularly, steps S107 to S108 may be omitted. it can.

  In step S105, the control unit 1 instructs the mobile communication terminal registered in step S104 to change the control of transmission of pedestrian mobile body information. Therefore, it is conceivable that the mobile communication terminal that has received the instruction transmits pedestrian mobile body information that does not include information indicating the current position of the pedestrian or does not transmit pedestrian mobile body information. In such a case, by directly requesting the pedestrian's mobile body information including the information indicating the current position of the pedestrian from the registered mobile communication terminal, the mobile communication terminal can request the pedestrian's current position. Pedestrian moving body information including information indicating the position can be received (acquired).

  To request the pedestrian's mobile body information including information indicating the current position of the pedestrian directly from the registered mobile communication terminal, the terminal device ID of the registered mobile communication terminal is added to the navigation device. 20 may be transmitted via the communication unit 8 to instruct to transmit pedestrian moving body information including information indicating the current position (adding the ID of the navigation device 20). Further, for example, information that instructs to transmit the pedestrian moving body information including information indicating the current position may be transmitted to the navigation device 20 using wireless communication different from ITS communication.

  In step S109, the control unit 1 determines whether or not a pedestrian is in the vehicle. The pedestrian in this step is a pedestrian who has been determined to have boarded the vehicle in step S103, and whether or not the pedestrian has boarded in this step (whether or not he / she got off) Is determined based on the current position of the pedestrian, the current position of the host vehicle, and the second predetermined range. FIG. 4 is a diagram showing an example of getting-off determination based on the second predetermined range.

  As described above, the second predetermined range is set to be wider than the first predetermined range. Therefore, although the pedestrian is in the vehicle, the detection accuracy of the current position of the pedestrian and the current position of the host vehicle is reduced, so that the current position of the pedestrian is not within the first predetermined range. However, if it is within the second predetermined range, it is not determined that the vehicle is not boarded (get off) (it is determined that the vehicle is being boarded).

  When the pedestrian is in the vehicle (Y in step S109), the process returns to step S107, and when the pedestrian is not in the vehicle (N in step S109), the process proceeds to step S110.

  In step S110, the control unit 1 cancels the registration of the terminal ID of the mobile communication terminal such as a mobile phone held by the pedestrian who has got off the vehicle from the storage area indicating that the mobile communication terminal is in the vehicle. Delete the terminal ID of the mobile communication terminal being used).

  In step S111, the control unit 1 instructs the mobile communication terminal whose registration has been canceled in step S110 to change the control of transmission of pedestrian mobile body information. The change of transmission control in this step is to instruct the mobile communication terminal to perform transmission of pedestrian mobile body information in the normal control state.

  In step S112, the control unit 1 changes the threshold value (second predetermined range) for boarding / exiting determination to the first predetermined range for the mobile communication terminal that gets off.

  In the flowchart of FIG. 2, processing is performed in this order for step S105 and step S106. However, this processing may be out of order, or simultaneous processing may be performed. The same applies to step S111 and step S112.

  In summary, in the present embodiment, the control unit 1 of the navigation device 20 uses the first predetermined range as a reference for boarding / exiting (boarding) of a mobile communication terminal that is not registered as being in the own vehicle (boarding) ) Is determined, but the determination of getting on / off (getting off) of the mobile communication terminal registered as being in the own vehicle is made on the basis of the second predetermined range. Further, only the mobile communication terminal registered as being in the own vehicle is instructed to perform transmission of the pedestrian's mobile body information in the special control state.

According to the present embodiment, when determining whether or not a pedestrian who has not boarded the vehicle (not registered as being in the vehicle) has boarded the vehicle, the first criterion is used as a criterion for determination. When determining whether a pedestrian who is in the vehicle (registered as being in the vehicle) is riding in the vehicle (whether the vehicle is getting off the vehicle) than the predetermined range Is set so that the second predetermined range, which is a criterion for determination, becomes wider, so that when the detection accuracy of the current position of the pedestrian and / or the current position of the own vehicle is lowered, the pedestrian is moved from the own vehicle. Although it is not getting off, it is not judged that it got off (it has not got on). Thereby, the other communication apparatus which received the mobile body information of the said pedestrian by frequently switching the case of transmitting in the normal control state and the case of transmitting in the special control state about the transmission of the mobile body information of the pedestrian Will not interfere with safe driving assistance.
[Second Embodiment]
A second embodiment of the mobile communication device of the present invention will be described with reference to FIG. FIG. 6 is a flowchart showing the flow of processing executed by the control unit 31 of the mobile phone 50 of the present invention. In the following description, the same parts as in the first embodiment (for example, explanation of terms, variability of timing for acquiring various types of information, unordered processing order, etc.) will be omitted as appropriate.

  In step S201, the control unit 31 acquires vehicle moving body information. The vehicle moving body information includes information indicating the vehicle ID (device ID of the in-vehicle communication device), information indicating the current position (latitude, longitude) of the vehicle, information indicating the traveling direction of the vehicle, and the moving speed of the vehicle. Information etc. are included.

  In step S201, the control unit 31 acquires vehicle moving body information. To be precise, the control unit 31 is a moving body of another moving body (such as another vehicle or a pedestrian) received by the communication unit 38. Get information.

  If the acquired moving body information of another moving body (another vehicle, pedestrian, etc.) is the moving body information of the vehicle, the control unit 31 proceeds to step S202 on the assumption that the moving body information of the vehicle has been acquired.

  The determination as to whether the acquired moving body information of another moving body (such as another vehicle or a pedestrian) is the moving body information of the vehicle can be made in the same manner as in step S101 described above.

  Next, in step S202, the control unit 31 has a pedestrian who owns his / her own terminal (mobile phone 50) (in this embodiment, “pedestrian who owns his / her own terminal (mobile phone 50)” is simply referred to as “pedestrian”). Get the moving body information. The pedestrian's moving body information includes information indicating the current position of the pedestrian detected by the current position detection unit 34, and the current position detection unit 34 (if the mobile phone 50 includes a traveling direction detection unit, the traveling direction detection unit Information indicating the traveling direction of the pedestrian detected by (good), information indicating the moving speed of the pedestrian detected by the speed detection unit 35, and the like.

  In step S203, the control unit 31 determines whether or not a pedestrian is on the vehicle. Whether the pedestrian is in the vehicle is determined based on the current position of the pedestrian, the current position of the vehicle, and the first predetermined range, as in the first embodiment.

When the pedestrian is in the vehicle (Y in step S203), the process proceeds to step S204. When the pedestrian is not in the vehicle (N in step S203), the process returns to step S201. The device ID of an in-vehicle communication device such as a navigation device mounted on a vehicle on which the pedestrian is riding is registered (stored) in a storage area indicating that the pedestrian is on the vehicle. In this embodiment, after this step, the boarding / departure determination is performed only for the current position of the registered vehicle, and the boarding / departure determination is not performed for the current positions of other vehicles (boarding / departure determination in step S209 described later). Only do). This is because a pedestrian does not get on two vehicles at the same time.

  In step S205, the control unit 31 performs transmission of pedestrian moving body information performed via the communication unit 38 in a special control state.

  In step S206, the control unit 31 changes the threshold value (first predetermined range) for getting on / off determination to the second predetermined range.

  In step S207, the control unit 31 acquires vehicle moving body information, and in step S208, the control unit 31 acquires pedestrian moving body information.

  In step S209, the control unit 31 determines whether or not a pedestrian is on the registered vehicle. In this step, whether or not the pedestrian is on board (whether or not the vehicle has got off) is determined (get-off determination) in the same manner as in the first embodiment. It is determined based on.

  When the pedestrian is in the registered vehicle (Y in step S209), the process returns to step S207. When the pedestrian is not in the registered vehicle (N in step S209), the process goes to step S210. move on.

  In step S210, the control unit 31 cancels the registration of the device ID of the in-vehicle communication device such as a navigation device mounted on the vehicle on which the pedestrian is riding from the storage area indicating that the pedestrian is on the vehicle. To do.

  In step S <b> 211, the control unit 31 performs transmission of pedestrian moving body information performed via the communication unit 38 in a normal control state.

  In step S212, the control unit 31 changes the threshold value (second predetermined range) for getting on and off to the first predetermined range.

  In summary, in the present embodiment, the control unit 31 of the mobile phone 50 uses the first predetermined range as a reference for pedestrian boarding / exiting determination (boarding determination) when the pedestrian is not registered as being in the vehicle. Entry / exit determination (boarding determination) is performed, but pedestrian boarding / departure determination (departure determination) when the pedestrian is registered to be in the vehicle is determined based on the second predetermined range (departure determination) )I do. When it is registered that the pedestrian is in the vehicle, transmission of the pedestrian's moving body information is performed in a special control state.

According to the present embodiment, the vehicle is more than the first predetermined range which is a criterion for determination when determining whether or not a pedestrian who has not boarded the vehicle (the vehicle is not registered) has boarded the vehicle. The second predetermined range, which is a criterion for determination when determining whether a pedestrian who has boarded (a vehicle is registered) has boarded the vehicle (whether the vehicle has got off the vehicle) Since it is set to be wide, when the detection accuracy of the current position of the pedestrian and / or the current position of the vehicle is lowered, the pedestrian has not got off the vehicle (not getting on) ) Is not determined. Thereby, the other communication apparatus which received the mobile body information of the said pedestrian by frequently switching the case of transmitting in the normal control state and the case of transmitting in the special control state about the transmission of the mobile body information of the pedestrian Will not interfere with safe driving assistance.
[Other embodiments]
In step S103 of the first embodiment and step S203 of the second embodiment, the control unit 1 determines the current position of the pedestrian based on the current position of the pedestrian, the current position of the vehicle (vehicle), and the first predetermined range. When the position is in the first predetermined range centered on the current position of the own vehicle (vehicle), it is determined that the pedestrian is on the own vehicle (vehicle). It is determined that the pedestrian is in the own vehicle (vehicle) when the position exists in the first predetermined range centered on the current position of the own vehicle (vehicle) for a predetermined time (multiple times). It is good to do.

  Thereby, it can be prevented that it is determined that the vehicle has just got on the vehicle (vehicle) when the pedestrian passes the vehicle (vehicle) side.

  Moreover, in the said embodiment, when a pedestrian gets in a vehicle, the control part 1 of a vehicle-mounted communication apparatus instruct | indicates to perform transmission of the pedestrian's mobile body information by a mobile communication terminal in a special control state, or mobile communication. Although transmission of the pedestrian's mobile body information performed by the control unit 31 of the terminal via the communication unit 38 is performed in the special control state, transmission of the vehicle's mobile body information by the in-vehicle communication device is performed in the special control state. It may be a thing.

  That is, when a pedestrian gets into the vehicle, the control unit 31 of the mobile communication terminal instructs the transmission of vehicle information on the vehicle by the in-vehicle communication device in a special control state, or the control unit 1 of the in-vehicle communication device. The transmission of vehicle moving body information performed through the communication unit 8 may be performed in a special control state.

  The same applies to when a pedestrian gets off the vehicle. When the pedestrian gets on the vehicle, the pedestrian gets off the vehicle when the vehicle information is transmitted in a special control state. In some cases, transmission of vehicle moving body information is performed in a normal control state (returned to a normal control state).

  When the pedestrian is in the vehicle, when the vehicle moving body information is transmitted in the special control state and the pedestrian moving body information transmission is in the normal control state, the pedestrian moving body When the information indicating the movement type is included in the information, the movement type may be changed to a vehicle or a pedestrian on board.

For example, the third communication The device may receive pedestrian moving body information from another communication device, and the communication unit 8 may receive pedestrian moving body information from the third communication device via wireless or wired communication. Similarly for transmission, the vehicle information of the own vehicle is transmitted from the communication unit 8 to the third communication device via wireless or wired communication, and the vehicle information of the own vehicle is transmitted from the third communication device to another communication device. May be sent.

  Moreover, in the said embodiment, the circular range (refer FIG. 3) centering on the present position of the own vehicle (pedestrian) is illustrated as a 1st predetermined range, and a 1st predetermined range is used as a 2nd predetermined range. A circle range (see FIG. 4) centered on the current position of the vehicle (pedestrian) whose radius is larger than (circle) is illustrated, but the first and second predetermined ranges are not limited to this, but other than a circle It may not be centered on the current position of the own vehicle (pedestrian) (for example, a position separated from the current position of the own vehicle by a predetermined distance backward in the traveling direction of the own vehicle). May be the center).

  Furthermore, in the mobile communication terminal that is determined to be on board in Embodiment 1 and performs transmission of pedestrian mobile body information in a special control state, even if a predetermined time or more has elapsed after performing in the special control state, If there is no instruction from the navigation device 20 to transmit the pedestrian's moving body information in the normal control state, the transmission of the pedestrian's moving body information may be performed in the normal control state.

  Further, after step S102 or step S202, it is determined whether or not an ID (terminal ID or device ID) included in the acquired moving body information of another moving body (pedestrian or vehicle) is registered (stored). If it is not registered (stored) (that is, if it is not on board), the processing of step S103 to step S106 (step S203 to step S206) is performed, and if it is registered (stored) (that is, it is on board) If it exists, it is good also as performing the process of step S109-S112 (step S209-S212).

  In the above embodiment, a navigation device (in-vehicle communication device) mounted on an automobile is illustrated as an example of the mobile communication device, but the mobile communication device is not limited to the navigation device as long as the mobile communication device is provided in the vehicle.

  The “mobile communication device provided in the vehicle” is not limited to a device fixed to the vehicle, and may be a device that can be removed from the vehicle (for example, a portable navigation device). In this case, for example, when a power supply (12 V) is received from a vehicle battery or the like, it can be determined that the vehicle is equipped. Various known methods can be used to determine whether the vehicle is equipped.
