Simultaneously with the screen display of the intention to cross and thank you, a voice output indicating the intention to cross and thank you may be performed by a car audio speaker (not shown) provided in the passenger compartment. Moreover, although this embodiment demonstrated the case where the vehicle interior notification means 14 was provided in the navigation apparatus 10, you may make it provide the vehicle interior notification means 14 separately from the navigation apparatus 10. FIG.

  The vehicle control device 15 performs the transmission control of the vehicle-side transmission unit 12 and the reception control of the vehicle-side reception unit 13 described above, and performs the notification control of the in-vehicle notification unit 14 when notification to the occupant is necessary. More specifically, when the crossing intention information is input from the vehicle-side receiving unit 13, the vehicle control device 15 performs notification control of the in-vehicle notification unit 14 so as to notify the occupant of information including at least the crossing intention information. Further, when an operation input is made to the vehicle operating means after the notification of the crossing intention information is made, a response signal including the identification information and the stop intention information received together with the above-described crossing intention information is transmitted from the vehicle side transmission means 12. Further, when a signal including thank-you intention information is input to the vehicle-side receiving unit 13 after transmitting the response signal, the vehicle control device 15 causes the in-vehicle notification unit 14 to notify the thank-you intention information.

The vehicle control device 15 includes a portable device recognition unit 16, a reception intensity determination unit 17, a traffic signal distance determination unit 18, and a position overlap determination unit 19.
The portable device recognition unit 16 recognizes the portable device 2 that has transmitted the signal based on the identification information of the portable device 2 input from the vehicle-side reception unit 13. For example, when a signal from a single portable device 2 is received by the vehicle-side receiving means 13, while recognizing the single portable device 2 based on the identification information, the signals from a plurality of portable devices 2a to 2n are recognized. When the signal is received by the vehicle-side receiving means 13, the portable devices 2a to 2n are recognized as different portable devices 2 based on the identification information.

  The reception strength determination unit 17 determines the reception strength of each signal received by the vehicle-side reception unit 13 when signals from the plurality of portable devices 2a to 2n are received. Here, the vehicle control device 15 obtains the signal with the highest reception intensity based on the determination result of the reception intensity determination means 17, specifies the portable device 2 that has transmitted the signal with the highest reception intensity from the identification information, and The portable device 2 is a notification target. Then, the in-vehicle notification means 14 notifies the crossing intention information and the current position information transmitted from the portable device 2 that is the notification target.

  When the portable device 2 is recognized by the portable device recognition unit 16, the traffic signal distance determination unit 18 navigates the current position information of the vehicle 3 and the position information of the traffic signal near the vehicle 3 based on the position information of the navigation device 10. It is acquired from the device 10 and it is determined whether or not the vehicle 3 is present at a position separated from the nearest traffic signal by a predetermined distance or more. And when it determines with the vehicle 3 existing in the position away from the nearest traffic signal more than predetermined distance, while the vehicle control apparatus 15 performs notification control of the in-vehicle notification means 14, the vehicle 3 is more than predetermined distance from the nearest traffic signal. When it is determined that the vehicle does not exist at a distant position, that is, when the vehicle 3 is present near the traffic signal, there is a possibility that excessive notification of the intention to cross will be made. Control is not performed. The traffic light distance determining means 18 merely determines the distance between the traffic light and the vehicle 3. However, for example, the target traffic light may be limited to traffic lights in the traveling direction of the vehicle 3.

  When the portable device 2 is recognized by the portable device recognition unit 16, the position overlap determination unit 19 acquires the position information of the building from the navigation device 10, and the position information of the recognized portable device 2 and the position information of the building are acquired. Based on the above, it is determined whether or not the position of the portable device 2 and the position of the building overlap. When it is determined that the position of the portable device 2 and the position of the building overlap, the user of the portable device 2 is in the building, does not intend to cross the road, and is an erroneous operation of the portable device operating means 4. Since it can be estimated, the notification control of the in-vehicle notification means 14 by the in-vehicle device 3a is not performed.

The traffic support system 1 in this embodiment has the above-described configuration. Next, an example of the operation of the traffic support system 1 will be described with reference to FIG.
First, in step S01, when the push button 23 of the portable device operating means 4 of the portable device 2 is pressed by a pedestrian or an occupant of a light vehicle similar to a pedestrian, the crossing intention information, the current position of the own device (portable device 2) Information and identification information of the own device (portable device 2) are transmitted from the portable device 2 to the in-vehicle device 3a of the nearby vehicle 3. At this time, the liquid crystal display 22 of the portable device 2 displays an upright humanoid illustration that means “stop” similar to the red light of the pedestrian traffic light in a red background, and further from the speaker “street” Outputs a voice indicating the intention to cross. By these audio output and illustration display, the user can recognize that the transmission of the intention to cross is accepted, and can further recognize that it is not in a state where it can still cross.

  On the other hand, when the crossing intention information, the position information, and the identification information transmitted from the portable device 2 by the in-vehicle device 3a of the vehicle 3 are received, the portable device 2 is recognized by the identification information, and the reception strength determination described above When the distance to the traffic signal is determined and the position of the recognized portable device 2 is overlapped with the position of the building, and the recognized portable device 2 is a notification target, the intention to cross is input For example, an illustration showing a pedestrian raising his hand and crossing is displayed on the monitor 14a of the in-vehicle notification means 14. Simultaneously with this monitor display, the position information of the portable device 2 is shown on the map, and the intention to cross is notified to the occupant of the vehicle 3 by voice output (not shown).

  Next, when the operation switch 34 of the steering wheel 35 is operated as a response to the crossing intention by the occupant of the vehicle 3 who has confirmed the crossing intention via the in-vehicle notification means 14 in step S02, the crossing intention information together with the stop intention information Is transmitted from the in-vehicle device 3 a to the portable device 2. On the other hand, when the stop intention information and the identification information are received by the portable device 2, when it is determined that the identification information and the identification information of the own device (portable device 2) collide with each other, that is, to the portable device 2. In the case of a response, the mobile device notification means 8 notifies the stop intention. Specifically, the vibrator vibrates the casing of the portable device 2, and the liquid crystal display 22 has a walking human shape that means “can cross” as well as the green light of the pedestrian traffic light. Is displayed on a blue background. By notifying the stop intention in this way, a pedestrian or a passenger of a light vehicle similar to a pedestrian can recognize that crossing has been permitted.

  In step S03, the push button 23 of the portable device operating means 4 is pressed (or long-pressed) by a pedestrian or an occupant of a light vehicle similar to a pedestrian after the stop intention is notified or while the stop intention is notified. ), The thank-you intention information is transmitted to the in-vehicle device 3a of the vehicle 3 together with the identification information. At this time, a voice indicating thank you “thank you” is output via the speaker of the portable device notifying means 8, and thus the user can recognize that the transmission of thank you information has been accepted.

  On the other hand, when the thank-you intention information is received by the in-vehicle device 3a of the vehicle 3, an image representing the thank-you intention including the characters “Thank You!” Is displayed on the monitor 14a of the in-vehicle notification means 14. Note that when the in-car informing means 14 informs the thank-you intention, the thank-you intention may be informed by audio output in addition to the image display, or the intent to express thanks may be informed only by sound output.

  Therefore, according to the traffic support system of the first embodiment described above, a pedestrian or an occupant of a light vehicle similar to a pedestrian operates the portable device operating means 4 of the portable device 2 and transmits a signal including crossing intention information. Then, the signal is received by the vehicle side receiving means 13 of the vehicle 3 to notify the occupant of the vehicle 3 of predetermined information including the intention to cross the mobile device 2 and the position information. Thereafter, the occupant of the vehicle 3 When the vehicle operation unit 11 is operated, a response signal including stop intention information is transmitted to the portable device 2 via the vehicle side transmission unit 12. And since the notification according to the reply signal received by the portable device side receiving means 7 of the portable device 2 is performed by the portable device notifying means 8, the intention to cross the pedestrian and the passenger of the light vehicle similar to the pedestrian and the occupant of the vehicle Stop intention, which is the intention of crossing permission from the pedestrian, can be clearly communicated with each other, and communication between the pedestrian and the occupant of the light vehicle similar to the pedestrian and the occupant of the vehicle can be achieved. Smooth traffic is possible.

  In addition, since the in-vehicle notification means 14 provides notification to the passenger of the vehicle 3 and the portable device notification means 8 provides notification to the pedestrian and pedestrian of the light vehicle occupant, particularly in bad weather, etc. Even if it is bad, it becomes possible to notify to a pedestrian, the passenger | crew of a light vehicle, and the passenger | crew of the vehicle 3 reliably, As a result, the safety on road traffic can be improved.

  Further, a signal including crossing intention information is received by the vehicle-side receiving means 13, and the position of the own vehicle is determined from the position of the traffic signal based on the position of the own vehicle on the road and the position of the traffic signal acquired by the navigation device 10. When it is determined that the distance is greater than or equal to the distance, notification control is performed by the vehicle control device 15 and predetermined information including the position information of the portable device 2 is notified to the passenger of the vehicle 3 by the in-vehicle notification means 14, Since notification by the in-vehicle notification means 14 can be performed only in places other than the place where attention should be paid, such as in the vicinity of a traffic light, it is possible to reduce troublesomeness due to excessive notification and effectively notify in a situation that requires attention. Can do.

  In addition, when the portable device 2 is recognized based on the identification information unique to the portable device included in the signal transmitted from the portable device 2 by the portable device recognition means 16, and a plurality of portable devices 2a to 2n are recognized, Among the received strengths of the signals transmitted from the portable devices 2a to 2n determined by the received strength determining means 17, the signal having the highest received strength, that is, the signal transmitted from the portable device 2 that is located closest to the vehicle 3 is received. Since the mobile device 2 is specified from the identification signal and only the information including the position information of the mobile device 2 is preferentially notified by the in-vehicle notification means 14, the most attention is given from the plurality of mobile devices 2a to 2n. It is possible to efficiently notify the occupant of the vehicle 3 of the intention of crossing by the pedestrian carrying the portable device 2 that seems to be necessary and the occupant of the light vehicle similar to the pedestrian.

  Further, when the position of the portable device 2 overlaps with the position of the building, notification control according to a response signal including a crossing intention transmitted from the portable device 2 is not performed. The excessive notification resulting from it can be prevented.

  Next, a traffic support system 101 according to a second embodiment of the present invention will be described with reference to the drawings. The traffic support system 101 according to the second embodiment has the configuration of the portable device 2 that includes the vehicle operation means 11, the vehicle side transmission means 12, and the vehicle side reception means 13 of the in-vehicle device 3a according to the first embodiment described above.
