  According to the mobile communication device configured as described above, a mobile communication device mounted on a mobile body receives a radio signal including evacuation recommendation information that urges the mobile body to evacuate from another mobile communication device. Then, a notification for urging a predetermined evacuation action for the moving body to the passenger of the moving body is made. Thereby, the passenger of a mobile body can grasp | ascertain easily that the said mobile body is in the condition which should take retreat action.

  (2) In the mobile communication device, the radio signal further includes azimuth information and position information of the other mobile body, and an acquisition unit that acquires the azimuth information and position information of the mobile body; A first determination for determining whether the azimuth of the moving body is included in a predetermined azimuth range including the azimuth of the other moving body using the moving body and the azimuth information of the moving body; and the other moving body and the A determination unit configured to perform a second determination to determine whether or not the moving body is traveling ahead of the other moving body using position information of the moving body, and the notification control unit includes the determination It is preferable to output the notification command when both of the determination results of the first determination and the second determination by the unit are affirmative.

In this case, when the mobile body travels in the same direction as the other mobile body and travels ahead of the other mobile body, a notification that prompts the passenger of the mobile body to perform a predetermined retreat action is made. The
Therefore, the moving body traveling in front of the other moving body takes a retreating action, so that the other moving body can smoothly travel without being obstructed by the moving body.
In addition, when the moving body is traveling in the opposite direction with respect to the other moving body, or when traveling behind the other moving body, a notification that prompts the occupant of the moving body to evacuate is issued. It is never done. Therefore, when the moving body does not need to take the evacuation action, it is possible to suppress notification that prompts the occupant of the moving body to perform the evacuation action.

(3) In the mobile communication device, the notification control unit calculates a distance between the other moving body and the moving body using the other moving body and position information of the moving body, and responds to the distance. It is preferable to change the command content of the notification command.
In this case, according to the distance between the other moving body and the moving body, it is possible to change the command content of the notification command for informing the occupant of the moving body to urge the evacuation action. For this reason, for example, when the notification to the passenger is performed by voice, the volume of the voice can be reduced when the distance is long, and the volume of the voice can be increased when the distance is short. Thereby, the passenger of a mobile body can grasp | ascertain easily the urgency of evacuation action.

(4) In the mobile communication device, the determination unit further uses the other moving body and the position information of the moving body, and the traveling lane in which the moving body is traveling is traveling in the other moving body. The third determination is made to determine whether or not the lane is the same as the traveling lane, and the notification control unit determines that all the determination results of the first to third determinations by the determination unit are affirmative.

In this case, for example, when a time zone in which the travel of the moving body is restricted in a predetermined travel lane and only another mobile body can travel is set in advance, the mobile body is connected to the predetermined travel lane in the time zone. If the vehicle is traveling in another lane in the same direction and the receiving unit does not receive a radio signal including evacuation recommendation information, that is, if no other moving object is traveling near the moving object, the passenger of the moving object Can be informed that the moving body can travel in the predetermined traveling lane. Thereby, the passenger of a mobile body can grasp | ascertain easily that the said mobile body can drive | work the said predetermined travel lane.

(10) In the mobile communication device, it is preferable that a frequency band of the radio signal is a 700 MHz band.
In this case, wireless communication according to the standard of the 700 MHz band intelligent transportation system is possible.

  (11) The computer program of the present embodiment is a computer program for causing a computer to function as the mobile communication device of (1). Therefore, the computer program of this embodiment has the same operational effects as the mobile communication device of (1) above.

A transmission unit capable of transmitting a radio signal addressed to the aircraft, and a transmission control unit configured to cause the transmission unit to transmit evacuation recommendation information for encouraging evacuation behavior of the other moving body.

  According to the mobile communication device configured as described above, the mobile communication device mounted on the mobile body evacuates the other mobile communication device mounted on the other mobile body to urge the other mobile body to retreat. A radio signal including recommendation information is transmitted. Therefore, for example, when another mobile communication device receives a wireless signal including evacuation recommendation information, if the passenger of the other mobile body is notified that the wireless signal has been received, Can easily grasp that there is a situation to take evacuation action.

(13) The mobile communication device may further include an acquisition unit that acquires azimuth information and position information of the mobile body, and the transmission control unit may receive the position information and the azimuth information acquired by the acquisition unit as the radio signal. It is preferable that it is further included in and transmitted to the transmitter.
In this case, when the other mobile communication device receives the wireless signal, the traveling direction and position of the moving body can be specified using the position information and the azimuth information of the moving body included in the wireless signal. Thereby, the passenger of the other moving body can grasp whether or not the other moving body should take a retreat action based on the traveling direction and position of the moving body.

(14) In the mobile communication device, it is preferable that the transmission control unit causes the transmission unit to transmit a radio signal including the evacuation recommendation information when the current time is included in a predetermined time zone.
In this case, for example, when a time zone for restricting the travel of another moving body in a predetermined travel lane is set in advance, the other travel is performed only when the other mobile body travels in the travel lane during the time zone. It is possible to notify the passenger of the body so as to prompt the evacuation behavior of the other moving body. As a result, when the other moving body is traveling in the travel lane other than the time zone, a notification for prompting the evacuation action to the passenger of the other moving body is not made. Therefore, when it is not necessary for the other moving body to take a retreating action, it is possible to suppress notification that prompts the passenger of the other moving body to perform the retreating action.

  (15) The computer program of the present embodiment is a computer program for causing a computer to function as the mobile communication device of (12). Therefore, the computer program of this embodiment has the same operational effects as the above mobile communication device (12).

In step S14, the control unit 32 (determination unit 322) of the in-vehicle communication device 2B mounted on the general vehicles 6A and 6B has the same traveling lane in which the host vehicle is traveling as the traveling lane in which the route bus 5 is traveling. A third determination is made to determine whether or not. This third determination can be made by comparing the position information of the route bus 5 included in the radio signal with the position information acquired from the host vehicle.
If the determination result of step S14 is negative, the control unit 32 ends the process.
When the determination result of step S14 is affirmative, the control unit 32 proceeds to next step S15.

In the example of FIG. 1, the general vehicle 6B is traveling on a traveling lane different from the route bus 5, so the determination result of step S14 is negative, and the control unit 32 of the vehicle ends the process.
On the other hand, since the general vehicle 6A is traveling on the same lane L1 as the route bus 5, the determination result in step S14 is affirmative, and the control unit 32 of the vehicle proceeds to the next step S15.
Since only the ordinary vehicle 6A proceeds to the next step S15 and subsequent steps, the following description will be given as processing executed by the in-vehicle communication device 2B of the ordinary vehicle 6A.

In step S <b> 15, the control unit 32 (determination unit 322) determines whether or not the position of the host vehicle in the height direction is included in a predetermined height range including the position of the route bus 5 in the height direction. Make a decision. This fourth determination can be made by comparing the position information of the route bus 5 included in the radio signal with the position information acquired from the host vehicle.
Note that the predetermined height range is the height of the general vehicle 6 even when the general vehicle 6 is traveling on the same route as the route bus 5 on a road with a height difference such as a slope. This is to include such a case because the position in the direction may be slightly different from the position in the height direction of the route bus 5.

When the determination result of step S15 is negative, the control unit 32 ends the process.
When the determination result of step S15 is affirmative, the control unit 32 proceeds to next step S16.
In the example of FIG. 1, since the position in the height direction of the general vehicle 6A is the same as the position in the height direction of the route bus 5, the determination result in step S15 is affirmative. Control goes to step S16.

  As an example in which the determination result in step S15 is negative, the following cases can be considered. That is, when the ordinary vehicle 6 travels on the elevated expressway and the route bus 5 is traveling on the ordinary road provided directly below the expressway, the ordinary vehicle 6 is in the same direction in front of the route bus 5. The traveling lanes in which the two vehicles 5 and 6 are traveling in a plan view overlap each other at the same position. In this case, since the position in the height direction of the general vehicle 6A is higher than the position in the height direction of the route bus 5, the determination result in step S15 is negative.

Next, in step S16, the control unit 32 determines whether or not the vehicle type of the own vehicle corresponds to a predetermined vehicle type, that is, whether or not the vehicle type of the own vehicle corresponds to a vehicle type permitted to travel on the bus-dedicated lane L1. Judgment is made.

If the determination result of step S17 is negative, the control unit 32 ends the process.
When the determination result of step S17 is affirmative, the control unit 32 calculates the distance between the host vehicle and the route bus 5 (step S18). The distance can be calculated by using position information of the route bus 5 included in the radio signal and position information acquired from the host vehicle.
And the control part 32 changes the instruction | command content of the alerting | reporting instruction | command notified to the passenger of the own vehicle so that predetermined | prescribed evacuation action is encouraged according to the calculated distance (step S19).

Specifically, the notification command output to the display 64 is, for example, a command content for reporting in small characters or inconspicuous character colors when the distance is long, and in large characters or conspicuous character colors when the distance is short. The content of the command to be notified.
The notification command output to the display 64 is, for example, a command content for notification with a small volume if the distance is long, and a command content for notification with a small volume if the distance is short.

Next, the control part 32 outputs the alerting | reporting instruction | indication which alert | reports so that the passenger of the own vehicle may carry out predetermined evacuation action to the display 64 and the speaker 65 of the own vehicle (step S20).
In the example of FIG. 1, since the passenger of the general vehicle 6A is notified, the predetermined evacuation action is a lane change from the bus-dedicated lane L1 to the travel lane L2.
In accordance with the notification command, the display 64 and the speaker 65, for example, output text information and guidance voices such as “Please change the lane to the next driving lane because the route bus is traveling on the bus lane”. To inform.

On the other hand, when the determination result of step S11 is negative, that is, when the route bus 5 is not approaching from behind the general vehicle 6, in step S21, the control of the in-vehicle communication device 2B mounted on the general vehicles 6A to 6D is performed. The unit 32 (determination unit 322) determines whether or not the host vehicle is traveling in another traveling lane L2 in the same direction as the bus-dedicated lane L1. This determination can be made based on the azimuth information and position information acquired from the own vehicle and the position information of the bus-dedicated lane L1.
Note that the location information of the bus-dedicated lane L1 may be stored in advance in the storage unit 33 of the own device, or stored in advance in the storage unit 13 of the roadside communication device 1, and the route information from the roadside communication device 1 is stored. You may make it acquire by communication between vehicles.

If the determination result of step S21 is negative, the control unit 32 ends the process.
If the determination result of step S21 is affirmative, the control unit 32 proceeds to the next step S22.
In the example of FIG. 1, the general vehicles 6A, 6C, 6D are traveling in a travel lane other than the travel lane L2, and therefore the determination result in step S21 is negative, and the processing by the control unit 32 of the vehicle ends. .
On the other hand, since the general vehicle 6B is traveling on the traveling lane L2, the determination result in step S21 is affirmative, and the control unit 32 of the vehicle proceeds to the next step S22.

In step S <b> 22, the control unit 32 of the general vehicle 6 </ b> B determines whether or not the current time is included in a restricted time zone in which the travel of the general vehicle 6 on the bus-dedicated lane L <b> 1 is prohibited.

<About effects>
As described above, according to the present embodiment, the in-vehicle communication device 2B mounted on the general vehicle 6 receives the radio signal including the evacuation recommendation information that prompts the lane change of the general vehicle 6 from the in-vehicle communication device 2A of the route bus 5. Then, a notification that prompts the passenger of the general vehicle 6 to change the lane of the general vehicle 6 is made. Thereby, the passenger of the general vehicle 6 can easily grasp that the host vehicle is in a situation to change lanes.

  Moreover, according to the distance between the route bus 5 and the general vehicle 6, the command content of the notification command for prompting the lane change is changed. For this reason, for example, when the notification is made by voice, the passenger of the general vehicle 6 changes the lane by decreasing the volume of the voice when the distance is long and increasing the volume of the voice when the distance is short. Can easily grasp the urgency of

Further, it is determined by the first determination that the direction of the general vehicle 6 is included in a predetermined azimuth range including the direction of the route bus 5, and the general vehicle 6 is traveling in front of the route bus 5 by the second determination. When it is determined that the lane change is made, a notification is made to prompt the passenger of the general vehicle 6 to change the lane.
Therefore, when the general vehicle 6 traveling in front of the route bus 5 changes lanes, the route bus 5 can smoothly travel on the bus-dedicated lane L1 without being obstructed by the general vehicle 6.
Further, when the general vehicle 6 is traveling in the opposite direction with respect to the route bus 5 or traveling behind the route bus 5, the passenger of the general vehicle 6 is prompted to change the lane. There is no notification. Therefore, when it is not necessary for the general vehicle 6 to change lanes, it is possible to suppress the notification that prompts the passenger of the general vehicle 6 to change lanes.

  The notification for prompting the lane change is further limited when it is determined by the third determination that the general vehicle 6 is traveling in the same lane as the route bus 5. For this reason, even when the general vehicle 6 is traveling in the same direction as the route bus 5, when the vehicle 6 is traveling in a travel lane different from the route bus 5, a notification that prompts the lane change is made. There is no. Therefore, when it is not necessary for the general vehicle 6 to change lanes, it is possible to suppress the notification that prompts the passenger of the general vehicle 6 to change lanes.

  Further, the notification that prompts the user to change the lane is further limited to the case where the position in the height direction of the general vehicle 6 is included in a predetermined height range including the position in the height direction of the route bus 5 according to the fourth determination. For this reason, for example, when the general vehicle 6 travels on an elevated highway and the route bus 5 travels on a general road provided directly below the highway, the height of the general vehicle 6 is increased. Since the position is out of the predetermined height range, there is no notification that prompts the lane change. Therefore, when it is not necessary for the general vehicle 6 to change lanes, it is possible to suppress the notification that prompts the passenger of the general vehicle 6 to change lanes.

  In addition, the notification that prompts the user to change the lane is further limited to a case where the vehicle type of the host vehicle does not correspond to a vehicle type that permits traveling on the bus-dedicated lane L1. For this reason, when the vehicle type of the host vehicle corresponds to the vehicle type that permits the travel, the notification that prompts the lane change is not made. Therefore, when the host vehicle does not need to change lanes, it is possible to suppress notification that prompts the passenger of the host vehicle to change lanes.

  In addition, the notification that prompts the user to change the lane is further limited to a case where the current time is included in a restricted time zone in which traveling of the general vehicle 6 on the bus-only lane L1 is prohibited. For this reason, when the general vehicle 6 is traveling on the bus-dedicated lane L1 other than the restricted time zone, there is no notification that prompts the lane change. Therefore, when it is not necessary for the general vehicle 6 to change lanes, it is possible to suppress the notification that prompts the passenger of the general vehicle 6 to change lanes.

Further, if the general vehicle 6 travels in another travel lane L2 in the same direction as the bus-dedicated lane L1 in the restricted time zone and the communication unit 31 has not received a radio signal including evacuation recommendation information, that is, a route bus If the vehicle 5 is not approaching from the rear of the general vehicle 6, a command for notifying the passenger of the general vehicle 6 of information indicating that the host vehicle can travel on the bus lane L1 is output. The passenger can easily grasp that the host vehicle can travel on the travel lane L1.
Moreover, since the frequency band of the radio signal transmitted from the route bus 5 to the general vehicle 6 is the 700 MHz band, wireless communication according to the standard of the 700 MHz band highway traffic system is possible.
