  The stop determination unit 42 determines whether or not the host vehicle has stopped based on the speed information of the host vehicle acquired from the vehicle control device 5. At this time, it is determined that the vehicle has stopped because the state where the speed is equal to or lower than the predetermined value has continued for a certain period of time. The stop determination may be performed based on the position information acquired by the position information acquisition unit 31. Moreover, this stop determination part 42 determines whether the position where the own vehicle stopped is on a road based on the positional information and map information of the own vehicle.

  In the traffic obstacle determination unit 43, the progress of the other vehicle is based on the position information of the own vehicle acquired by the position information acquisition unit 31, the position information of the other vehicle acquired from the in-vehicle terminal device 3 of the other vehicle, and the map information. It is determined whether or not the own vehicle is in front of the direction and the own vehicle (stopped vehicle) hinders the passage of other vehicles (running vehicles).

  Here, when a stopped vehicle obstructs the passage of a traveling vehicle, the width of the road is narrow and the traveling vehicle cannot pass beside the stopped vehicle, or the road is congested, This is the case when the lane that moves to the lane cannot be changed, when there is a parked vehicle in the left lane when turning left at the next intersection, or when there is a parked vehicle at the entrance of the parking lot.

  In addition, the message transmitted from the in-vehicle terminal device 3 of the other vehicle includes information on the size of the vehicle. Based on this information and information on the width of the road included in the map information, the stopped vehicle It is determined whether or not the traveling vehicle can pass by. In addition, it is possible to determine whether or not the lane can be changed by acquiring traffic information related to the traffic congestion situation on the road from the traffic information providing device. Note that the “running vehicle” may include a vehicle that is temporarily stopped due to a stoppage of a stopped vehicle or a vehicle that is temporarily stopped due to a red light.

  Next, an outline of processing performed in the wireless communication system will be described. FIG. 4 is a sequence diagram illustrating an outline of processing performed in the wireless communication system.

In addition, since the vehicle-mounted terminal device 3 has registered in advance the terminal ID of the driver's pedestrian terminal device 1, the driver's pedestrian terminal device 1 can be specified as the destination of the stop notification message.

  The in-vehicle terminal device 3 does not transmit a stop notification message addressed to the driver's pedestrian terminal device 1 but transmits vehicle information in normal inter-step communication to the surroundings, and receives the vehicle information. The pedestrian terminal device 1 of the person may make a predetermined determination. However, the case where the stop notification message is transmitted is preferable in terms of reducing the amount of signal communication.

  Next, when the driver's pedestrian terminal device 1 receives the stop notification message including the position information transmitted from the in-vehicle terminal device 3 of the stopped vehicle, the driver performs indoor determination as to whether the driver is indoors, When the driver is indoors and the driver's position information can be acquired, distance determination is performed regarding whether or not the stopped vehicle and the driver are separated from each other by a predetermined distance or more. If the driver is indoors, or the parked vehicle and the driver are separated from each other by a predetermined distance or more, a long-distance notification message indicating that the driver is not near the vehicle (the driver's location information is displayed).

  In the embodiment described above, the indoor determination and the distance determination are performed in the driver's pedestrian terminal device 1, but in the present embodiment, the indoor determination and the distance determination are performed in the in-vehicle terminal device 3 of the stopped vehicle. I have to. In this case, the driver's pedestrian terminal device 1 only performs satellite positioning determination regarding whether or not satellite positioning is possible, and transmits the determination result and the driver's position information to the in-vehicle terminal device 3 of the stopped vehicle.

  Next, a procedure of processing performed by the in-vehicle terminal device 3 will be described. FIG. 20 is a flowchart showing a procedure of processing performed in the in-vehicle terminal device 3.

  In the vehicle-mounted terminal device 3, as in the first embodiment (see FIG. 5), stop determination is made (ST101). If the host vehicle stops (Yes in ST101), the process proceeds to the stopped vehicle. . Here, first, in the same manner as in the first embodiment (see FIG. 5), the on-road stop determination is performed (ST102).

  Here, when the host vehicle is located on the road (Yes in ST102), the communication unit 32 transmits a positioning inquiry message to the driver's pedestrian terminal device 1 (ST141).

  And in the communication part 32, if the positioning result message (a driver's positional information is included) transmitted from a driver's pedestrian terminal device 1 is received (it is Yes at ST142), a driver will be indoors according to a positioning result. (ST143).

  Here, when the driver is not indoors (Yes in ST143), next, the position information of the host vehicle acquired by the position information acquisition unit 31 and the driver's acquired from the driver's pedestrian terminal device 1 are displayed. Based on the position information, it is determined whether the driver and the stopped vehicle are separated by a predetermined distance or more (ST144).

  Here, when the driver is indoors (No in ST143) and when the driver and the stopped vehicle are separated from each other by a predetermined distance or more (Yes in ST144), the communication unit 12 uses the surrounding in-vehicle terminal 3 The status notification messages are exchanged between the vehicle and the vehicle, and position information of other vehicles existing around the host vehicle is acquired (ST105).

  The subsequent steps are the same as in the first embodiment (see FIG. 5). Further, when the host vehicle is not stopped (No in ST101), the process proceeds to the traveling vehicle. The process at this time is the same as that of the first embodiment (see FIG. 5).

  Next, a procedure of processing performed by the pedestrian terminal device 1 will be described. FIG. 21 is a flowchart showing a procedure of processing performed by the pedestrian terminal device 1.

  In the pedestrian terminal device 1, first, when the communication unit 12 receives a message for inquiring the positioning transmitted from the in-vehicle terminal device 3 of the stopped vehicle (Yes in ST211), the satellite information can be measured by the position information acquisition unit 11. It is determined whether or not (ST202).

  If satellite positioning is impossible (No in ST202), a positioning result message indicating that satellite positioning is disabled is transmitted to the in-vehicle terminal device 3 of the stopped vehicle (ST212). On the other hand, if satellite positioning is possible (Yes in ST202), a positioning result message indicating that satellite positioning is possible is transmitted to the in-vehicle terminal device 3 of the stopped vehicle (ST213).

  The subsequent steps are the same as in the first embodiment (see FIG. 6).

  In the eighth embodiment, the distance determination is performed by the in-vehicle terminal device 3 of the stopped vehicle on the premise of the first embodiment. However, the distance determination of the stopped vehicle is performed on the assumption of the other embodiments. It is also possible to carry out with the in-vehicle terminal device 3. For example, in the second embodiment (see FIG. 7) and the third embodiment (see FIG. 9), the traffic obstacle determination is performed by the in-vehicle terminal device 3 of the traveling vehicle. Can be performed by the in-vehicle terminal device 3 of the stopped vehicle.

  As described above, the embodiments have been described as examples of the technology disclosed in the present application. However, the technology in the present disclosure is not limited to this, and can be applied to embodiments in which changes, replacements, additions, omissions, and the like have been performed. Moreover, it is also possible to combine each component demonstrated by said embodiment into a new embodiment.

  For example, in the above-described embodiment, as one of the conditions when notifying the driver of the movement request, the traffic obstacle determination regarding whether or not the stopped vehicle obstructs the passage of the traveling vehicle is performed. The driver may be notified of the movement request only by the presence of the traveling vehicle near the vehicle.

  Further, in the above-described embodiment, a road stop determination is made regarding whether or not the stopped vehicle is located on the road, or a parking stop prohibition determination is made regarding whether or not the stopped vehicle has stopped in a legal parking stop prohibited area. However, you may make it determine whether a stop vehicle is located in the area where the complaint of annoying parking frequently occurs. In this case, complaints regarding nuisance parking are collected by the server device from the pedestrian terminal device 1 or the in-vehicle terminal device 3, and the server device performs a necessary aggregation process to relate to an area where nuisance parking complaints frequently occur. Information may be provided to the in-vehicle terminal device 3.

  In the above-described embodiment, the case where the driver of the stopped vehicle is notified of the movement request and the driver moves the stopped vehicle has been described. Also good. That is, when the stopped vehicle is an autonomous driving vehicle, when the in-vehicle terminal device 3 of the stopped vehicle receives the movement request message, the vehicle departs and travels on an appropriate road to pass the traveling vehicle to the original stop position. The automatic operation is performed so that it returns. In this case, when the driver performs an operation of transmitting a movement request message to the driver's pedestrian terminal device 1 and approving the movement of the parked vehicle, the parked vehicle may perform a temporary retreat automatic driving.

  Moreover, although the said embodiment demonstrated the example of street parking, the place where a vehicle stops is not limited to a road, For example, a disabled person provided in the parking lot of various facilities, such as a supermarket It may be a private parking space. In this case, since a vehicle (unauthorized vehicle) on which the disabled person does not ride is parked in the parking space for the disabled person, if the vehicle (permitted vehicle) on which the disabled person gets cannot be parked, annoying parking is performed.

  Therefore, when a licensed vehicle tries to park in the parking space for disabled people, and the unauthorized vehicle is parked in the parking space for disabled people, whether the driver of the parked unauthorized vehicle leaves the vehicle. Alternatively, when indoors, a movement request message is transmitted from the in-vehicle terminal device 3 of the unauthorized vehicle or the in-vehicle terminal device 3 of the permitted vehicle to the pedestrian terminal device 1 of the driver of the unauthorized vehicle, and the driver's pedestrian terminal The device 1 notifies the driver of the stopped vehicle of the movement request.

  In addition, when a device (for example, a roadside device) installed in a parking lot exchanges a message between the in-vehicle terminal device 3 of the unauthorized vehicle and the in-vehicle terminal device 3 of the permitted vehicle, and satisfies the notification condition of the movement request Alternatively, a movement request message may be transmitted to the driver's pedestrian terminal device 1.

  In this case, by registering in advance in the in-vehicle terminal device 3 as attribute information that the disabled person is in a vehicle (permitted vehicle), a movement request is limited to a vehicle in which the disabled person does not get on (unauthorized vehicle). Can be sent. Moreover, it can be determined that the vehicle is parked in the parking space for the handicapped person by registering in advance the parking information related to the parking space for the handicapped person in the map information.

  In the above-described embodiment, in the pedestrian terminal device 1, when the driver is outdoors in the vicinity of the parked vehicle, the driver of the parked vehicle is not notified of the movement request. Being in the vicinity of the vehicle is regarded as an emergency, and a message including the emergency notification is transmitted to the in-vehicle terminal device 3 of the stopped vehicle, and further, the message including the emergency notification is stopped. You may make it transmit from the vehicle-mounted terminal device 3 of this to the vehicle-mounted terminal device 3 of a traveling vehicle. Not only the emergency notification but also information indicating the status of the corresponding vehicle such as parked due to a failure or parked for lifesaving may be notified at the same time.

  In this case, when the in-vehicle terminal device 3 of the traveling vehicle receives a message including an emergency notification from the in-vehicle terminal device 3 of the stopped vehicle, the occurrence of the emergency is determined based on the instruction from the in-vehicle terminal device 3. The car navigation device 4 is caused to perform an output operation (for example, screen display or audio output) to notify the person. Note that the in-vehicle terminal device 3 itself may perform an output operation for notifying the driver of the traveling vehicle that an emergency has occurred.

  Here, an emergency situation includes a case where an accident or failure occurs, or a case where an injured person or suddenly ill person on the road is rescued. By preventing the driver of the traveling vehicle from knowing that such an emergency has occurred, it is possible to prevent accidents where the traveling vehicle collides with an injured person, a suddenly ill person on the road, or a driver who provides relief. In addition, it is possible to prevent the traveling vehicle from being damaged by fragments of the vehicle damaged by an accident.

  Further, when the pedestrian terminal device 1 of the driver of the stopped vehicle receives the movement request message transmitted from the in-vehicle terminal device 3 of the stopped vehicle, an answer to the effect that the vehicle is moved immediately or the vehicle immediately in an emergency situation. The driver inputs an answer indicating that the mobile information terminal device 2 cannot be moved to the mobile information terminal device 2 through a screen operation or the like on the portable information terminal device 2, and sends a message including the answer content in response to the driver's input operation. You may make it notify to the driver of a traveling vehicle by transmitting to the apparatus 3 and the reply from the driver of a parked vehicle.

  Further, communication other than vehicle-to-vehicle communication can be used for communication from the vehicle to the vehicle. The notification that the vehicle that is obstructing traffic is parked / stopped should only be given to the following vehicle in the same lane as the parking / parking location. Notification is not required. For this reason, it is also effective to use visible light communication that can communicate only in a specific area. For example, a visible light communication device can be mounted on a brake lamp or a hazard lamp of a car to notify a subsequent vehicle. In addition, visible light communication equipment is mounted on road signs, reflectors at the time of accidents, traffic lights, etc., position information etc. are notified from roadside terminals of parked vehicles to road signs, etc., followed by road signs etc. by visible light communication It is also possible to notify the vehicle. Furthermore, not only information on parked vehicles but also information on pedestrians such as jumping out of children and forced road crossing of elderly people can be collected in a communication device mounted on traffic lights etc. and notified to subsequent vehicles It is.

  In addition, communication with the following vehicle is performed by visible light communication only when the vehicle is unavoidably parked for reasons such as an accident or lifesaving, otherwise communication with the subsequent vehicle is performed by inter-vehicle communication. Also good. By doing this, there is an effect that it is possible to promptly notify the following vehicle that the vehicle is unavoidably parked for reasons such as an accident or lifesaving.

  The present invention is effective not only on general roads but also on expressways. For example, if there is a parked vehicle at a place that is not parked or stopped other than an interchange or a service area, a message including an emergency notification is notified to the following vehicle. In this way, the presence of a vehicle parked on the shoulder due to a vehicle failure or the like is notified, and at the same time, the subsequent vehicle is notified that there is a pedestrian on the shoulder, reducing accidents on the highway. It becomes possible.

  Further, the present invention is effective not only for parking and stopping vehicles but also for application and monitoring of elderly people and children. When a child is more than a predetermined distance away from the parent, or when an elderly person is more than a predetermined distance away from the family or home, an alarm display is displayed on the parent or family's terminal so that the elderly or child can be watched over. Become. Further, even when a child or an elderly person is in a place that should not be originally intended or a dangerous place, an alarm can be displayed on a parent or family terminal.

  Furthermore, it is also effective to apply the present invention to roll calls in group trips and the like. For example, when a predetermined time arrives, if a traveler is located at a distance of a predetermined distance from a bus or the like, it is possible to notify the corresponding traveler that the departure time of the bus or the like is approaching.
