Description

The present invention relates to a vehicle proximity alarm sound output device management system .

  For quiet vehicles such as electric vehicles such as electric cars and hybrid cars, a proximity warning sound is generally emitted from an external speaker to inform pedestrians around the vehicle that the vehicle is approaching. A vehicle proximity alarm sound output device for output is mounted (see Patent Document 1). Since such a vehicle proximity alarm sound output device continues to sound a proximity alarm sound from an external speaker at all times from ON to OFF of the vehicle operation switch and ignition switch, if the volume is too high, it will become noise to the surroundings. For this reason, the sound volume is kept relatively small.

And a management device 5 capable of communicating via a predetermined communication means 4. The vehicle 2 according to the present embodiment is a vehicle such as an electric vehicle such as an electric vehicle or a hybrid car, and is a relatively quiet vehicle even during traveling because the vehicle 2 is driven by an electric drive source such as an electric motor.

  The vehicle proximity alarm sound output device management system 1 includes a proximity alarm device 20 that continuously outputs a predetermined proximity alarm sound for notifying the proximity of the vehicle from the external speaker 21 to the vehicle periphery while the host vehicle 2 is traveling. The car navigation device 10 capable of detecting entry into a plurality of predetermined traveling areas stored in the storage device 15 (may include an approach within a predetermined contact distance or only the approach); A drive recorder device 30 that acquires warning target information for detecting a predetermined warning target around the vehicle during traveling of the vehicle 2 is connected via an in-vehicle communication means (in-vehicle LAN) 3. The

  The proximity alarm device 20 is a proximity alarm sound output means for outputting a proximity alarm sound from the external speaker 21 to inform the pedestrians around the vehicle that the vehicle is approaching. This is a well-known device that always sounds a proximity alarm sound from an external speaker from ON to OFF of a switch. Here, a proximity alarm sound is output when the ignition switch 6 is ON.

  The car navigation device 10 has a position detection unit 12 that detects the position of the host vehicle 2 with respect to a navigation control unit 11 having a CPU, a ROM, and a RAM, a known screen display unit such as a liquid crystal display, and a known speaker. An output unit 13 having an audio output unit, a known operation input unit 14 such as a mechanical switch, a touch panel, a remote controller, and an audio input unit, and a storage device (vehicle storage unit) 15 such as a hard disk drive are connected. Configured. The control unit 11 can perform control based on the navigation program and data stored in the storage device 15. More specifically, the navigation function can be executed by the control unit 11 executing the map data or the navigation program 29d stored in the storage device 15, for example, from the operation input unit 14 to the destination set by the user. The route guidance can be performed by display on the display unit constituting the output unit 13 or voice output from the voice output unit. The position detection unit 12 is a position information acquisition unit that acquires its own position based on radio waves from a satellite, and is a known unit having a GPS (Global Positioning System) receiver and the like.

  The drive recorder device 30 is a device in which a camera 31, which is a vehicle forward photographing device, divides a photographed image that is always photographed from ON to OFF of a vehicle operation switch or an ignition switch at predetermined intervals and stores it in a storage unit 35 for a certain period. It is. Here, as shown in FIG. 2, while the photographing and the storage of the photographed video in the storage unit 35 are started when the ignition switch 6 is turned on (S 301), the photographing content (warning target information and reaction behavior) Information) is distributed to the management device 5 in real time (S302: alert target information transmitting means and reaction behavior information transmitting means). In this case, the shooting and storage are terminated when the ignition switch 6 is turned off. The video taken by the camera 31 is a moving image, and for distribution (S2), the moving image is distributed in real time in a streaming format, or a still image captured from the moving image is acquired every predetermined time, and the still image is captured. There are methods such as sequentially delivering images in real time. Note that while the captured moving image is stored and accumulated in the storage unit 35, the moving image is deleted in order from a predetermined period.

  The management device 5 is configured as a device in which a storage device (management-side storage unit) 55 such as a hard disk drive is connected to a control unit 50 having a CPU, ROM, and RAM. As shown in FIG. 3, the storage device 55 stores area volume information in which the volume of the proximity alarm sound output from the vehicle 2 is associated with each of a plurality of predetermined traveling areas partitioned on the map. . This area volume information is also stored in the storage device 15 of each vehicle 2, and the latest area volume information stored in the management device 5 is distributed to each vehicle 2 as update information, whereby the area volume of each vehicle 2 is stored. Information is updated.

  Note that the travel area of the present embodiment is partitioned and set so as to have one each of nodes such as intersections and branches in the road network on the map and links linking them. For a link with a long distance, a travel area is set by dividing the link in the length direction. In this example, it is assumed that the driving area is set continuously without interruption for all roads, but there is a road section where the driving area is set locally and the driving area is not set. It may be.

  By the way, in the vehicle proximity alarm sound output device management system 1 according to the present embodiment, as the vehicle 2 starts traveling, the output of a predetermined proximity alarm sound for notifying the vicinity of the vehicle 2 about the proximity thereof. When an entry into a predetermined travel area is detected, the output volume of the proximity alarm sound is changed to a volume corresponding to the detected travel area, and the alert target in the close friend travel area A process of adjusting the volume according to the presence of is performed. Specifically, the process shown in FIG. 4 is performed in such a manner that the control unit 11 on the vehicle 2 side and the control unit 50 on the management device 5 side execute in cooperation.

  First, when the ignition switch 6 is turned on, output of a predetermined proximity alarm sound is started from the speaker 21 of the proximity alarm device 20 around the outside of the vehicle (S11: proximity alarm sound output means). Note that the volume at the start is the default volume.

  Subsequently, the control unit 11 detects the entry of the host vehicle 2 into a new travel area. (S12: Area detection means). Note that since the travel area is not recognized immediately after the start, this determination process is always executed immediately after the start. Here, detection of entry into the travel area includes area position information indicating the position of each travel area stored in the storage device 4, and own vehicle position information indicating the current position of the host vehicle 2 detected by the position detection unit 12. Based on the above, it is made in the form of determining the presence or absence to the travel area.

  When it is determined that the host vehicle 2 has entered a new travel area (S12: Yes), the control unit 11 uses the volume of the proximity alarm sound corresponding to the travel area that has entered into the area volume information stored in the storage device 15. Based on this, the specified volume is newly set (S13: volume changing means). Then, area entry information in which the area position information indicating the entered travel area is associated with the volume information indicating the newly set volume is transmitted to the management device 5 (S14: area entry information transmitting unit). .

  On the other hand, as shown in FIG. 2, the control unit 50 of the management device 5 captures a video image of the camera 31 (warning target information and reaction behavior information) transmitted in real time from the drive recorder device 30 of the vehicle 2. It is continuously received successively and stored in the storage device 55 (S22: alert target information receiving means and reaction behavior information receiving means). When the area entry information transmitted from the vehicle 2 is received as described above (S22: area entry information receiving means), the presence area of the transmission source vehicle 2 is determined in advance based on the area entry information. The travel area is identified (S23: area identifying means).

  Further, when receiving the area entry information, the control unit 50 of the management device 5 detects a predetermined alert target existing around the vehicle of the transmission source vehicle 2 (alarm target detection means). Specifically, the control unit 50 is determined in advance based on the latest captured video (warning target information) of the camera 31 received at a timing after reception of the area entry information. The presence or absence of a warning target is specified (S24: warning target specifying means). That is, here, the control unit 50 specifies a predetermined alert target such as a pedestrian or a traveling vehicle by image analysis such as pattern matching with respect to an image captured by the camera 31 that images the front of the vehicle. The captured image to be analyzed is when the area entry information transmitted when the vehicle 2 enters a certain traveling area is received, and when the subsequent captured image, that is, when the vehicle 2 exists in the traveling area. Therefore, the presence / absence of a warning target in the travel area is specified.

  In addition, the alert target detection means in this embodiment includes an alert target information acquisition means (S301), an alert target information transmission means (S302), an alert target information reception means (S21), and an alert target identification means (S24). , And is configured. The identification result by the alert target identifying means becomes the detection result of the alert target detecting means.

  When it is specified that there is the above-mentioned alert target (S25: Yes), the control unit 50, based on the specification result, the control unit 50 determines the travel area (most recent) in which the transmission source vehicle 2 of the received area entry information exists. The area sound volume information stored in the storage device 55 is updated so that the set sound volume of the proximity warning sound in the travel area specified in S23) is changed (management-side update means).

  Here, first, the control unit 50 detects a predetermined reaction behavior with respect to the proximity warning sound output from the transmission source vehicle 2 of the received area entry information, based on the specified warning target. (Reaction behavior detection means). Specifically, the control unit 50 determines whether or not the identified alert target has a predetermined reaction behavior based on the captured video (alarm target information) of the camera 31 received at a timing after reception of the area entry information. Is identified (S26: reaction behavior identifying means). That is, here, since the control unit 50 has already specified a warning target such as a pedestrian or a traveling vehicle by image analysis such as pattern matching with respect to a captured image of the camera 31 that has captured the front of the vehicle, the identification of the warning target is specified. The vehicle is continuously tracked for images taken by the camera 31 thereafter, and the target of the warning is tracked. Based on the result of the tracking, the target of the warning is determined in advance such as looking back here. If there is an action, a predetermined vehicle avoidance action such as moving to the side of the road, or an excessive reaction action such as momentarily trembling or standing, etc. If is not specified, it is specified that there is no reaction behavior. In addition, all the reaction behaviors here can be paraphrased as behaviors (warning target recognition behaviors) that are performed when the alert target recognizes the proximity warning sound. Here, a plurality of response actions are set in advance and the type is set as described above. Has been made.

  The reaction behavior detection means in this embodiment includes reaction behavior information acquisition means (S301), reaction behavior information transmission means (S302), reaction behavior information reception means (S22), and reaction behavior identification means (S26). , And is configured. The identification result by the reaction behavior identification means becomes the detection result of the reaction behavior detection means.

  When it is identified that the reaction behavior has occurred (S27: Yes), the control unit 50 identifies whether or not the identified reaction behavior is the excessive reaction behavior (S28: excessive reaction behavior identification means). When it is identified as an action (S28: Yes), the control unit 50 generates a proximity alarm sound in the travel area (the travel area identified in the latest S23) in which the transmission source vehicle 2 of the received area entry information is present. The area volume information stored in the storage device 55 is updated so as to reduce the set volume (here, 1 level) (S29: management-side update means). Then, as the update information, at least the update information in which the area position information indicating the travel area where the transmission source vehicle 2 of the received area entry information exists and the volume information indicating the volume to be newly set is associated is transmitted. It transmits to the former vehicle 2 (S30: update information transmission means).

  When it is specified that there is no reaction behavior (S27: No), the control unit 50 determines that there is no reaction behavior in the traveling area where the transmission source vehicle 2 of the received area entry information exists. Based on the past cases, it is determined whether or not a predetermined high-frequency occurrence condition is satisfied (S31). If the condition is satisfied (S31: Yes), the set sound volume of the proximity alarm sound in the travel area is determined. The area volume information stored in the storage device 55 is updated so as to increase (in this case, increase by one level) (S32: management-side update means). Then, as the update information, at least the update information in which the area position information indicating the travel area where the transmission source vehicle 2 of the received area entry information exists and the volume information indicating the volume to be newly set is associated is transmitted. It transmits to the former vehicle 2 (S33: Update information transmission means).

  Here, it is determined that the high-frequency occurrence condition is satisfied when it is determined that the reaction action has not been performed continuously for a predetermined number of times (for example, three times) according to the current case. However, the number of times that the reaction action is not performed can be added only by 1 after the vehicle 2 enters the travel area. Further, 1 is added when the vehicle 2 newly entering the travel area does not have the reaction behavior.

  Further, the update information (S30, S33) transmitted here may be all area volume information stored in the storage device 55.

  When the transmission of the update information to the transmission source (S30, S33) ends, the presence / absence of reception of the area entry information is determined again (S22), and the subsequent processing is repeated.

  At this time, if the area entry information is newly received (S22: Yes), the existence area of the transmission source vehicle 2 is specified as a new travel area (S23), and the subsequent processing is new. It is executed as relating to the travel area specified in (1). On the other hand, if the area entry information is not newly received (S22: No), the subsequent processing is executed again as related to the travel area specified most recently.

  Here, the processing returns to the control unit 11. After the new volume of the proximity alarm sound is set (S13, S17), when the control unit 11 receives the update information transmitted from the management apparatus 5 (S15: update information receiving means), the control unit 11 adds the received update information. Based on this, the area volume information stored in the storage device 15 is updated (S16: vehicle-side update means). That is, the control unit 11 sets the volume corresponding to the travel area indicated by the area position information included in the update information, out of the area volume information stored in the storage device 15, and the volume (volume information indicated by the volume information included in the update information). Change to the volume indicated by. And the control part 11 sets the volume of the proximity alarm sound corresponding to the driving | running | working area where the vehicle 2 exists now based on the updated area volume information, and changes an output volume (S17).

  After changing the volume of the contact alarm sound, the control unit 11 ends this process when the ignition switch 6 is turned off (S18: Yes). When the ignition switch 6 is kept ON (S18: Yes), the process returns to the detection (S12) of the presence or absence of entry into a new travel area. Therefore, if there is no entry into a new travel area, the reception of update information is awaited (S15), and volume adjustment in the current travel area is repeated.

  Even in a situation where the communication between the vehicle 2 and the management device 5 is interrupted, the vehicle 2 is approaching at a volume corresponding to the travel area that has entered based on the area volume information stored in its own storage device 15. It is configured to output an alarm sound.

  Thus, in the present embodiment, when the vehicle 2 enters a certain travel area, the volume of the proximity alarm sound is changed to the volume corresponding to the entered travel area, and the volume is a warning target in the travel area. Is detected (adjusted) according to the reaction behavior.

  In the present embodiment, the area volume information stored in the vehicle 2 based on the area volume information stored in the management device 5 (area volume information referred to for setting the volume of the proximity alarm sound when entering the area). Is updated. Furthermore, the area sound volume information stored in the management device 5 is also updated to the optimum one according to the detection of the warning target in each traveling area and the reaction behavior of the warning target.

  As mentioned above, although one Embodiment of this invention was described, this is only an illustration to the last, and this invention is not limited to this. For example, various modifications based on the knowledge of those skilled in the art are possible, such as omitting some of the configuration requirements in the above-described embodiment and further adding other configuration requirements. The same applies to the embodiments described below.

When the alert target is detected, it is also used as reaction behavior information for detecting the predetermined reaction behavior of the alert target for the output proximity alarm sound. It may be. For example, as illustrated in FIG. 7, another detection unit 16 that acquires reaction behavior information may be provided, and the reaction behavior may be detected from the detection result.

  In the above embodiment, the volume of the proximity warning sound is determined for each travel area, but the control unit 11 identifies a predetermined travel situation and determines the predetermined travel situation with respect to the travel area. You may make it correct | amend the sound volume determined by this. In the vehicle proximity alarm sound output device management system 1 shown in FIG. 5, a traveling state acquisition unit 16 that acquires traveling state information for detecting a predetermined traveling state is connected to the control unit 11. 11 specifies the current driving situation from the acquired driving situation information, and sets the volume of the proximity alarm sound set based on the area volume information stored in the storage device 15 according to the specified driving situation. To correct and set. Here, in accordance with the correction information shown in FIG. 6, the volume change amount corresponding to the specified driving situation is added to the volume of the proximity alarm sound set based on the area volume information stored in the storage device 15. It is corrected in the form.

  In the above embodiment, the alert target detection means and the reaction behavior detection means are configured to cooperate on the vehicle 2 side and the management device 5 side, but may be configured to be completed only on the vehicle side. . For example, as shown in FIG. 7, the drive recorder 30 is caused to function as a warning target detection means and / or a reaction behavior detection means by directly analyzing an image captured by the camera 31, and the control unit 11 acquires the result. You may make it perform volume setting. The control unit 11 may acquire a captured image of the camera 31 from the drive recorder 30, and the control unit 11 may cause the image to be analyzed to function as a warning target detection unit and / or a reaction behavior detection unit.

  In the above embodiment, the car navigation device 10 having the function of the drive recorder device 30 may be provided.

  In the above embodiment, when it is specified that there is a warning target (S25: Yes), the control unit 50 detects a reaction behavior from the specified warning target, and based on the detection result, the control unit 50 The area volume information stored in the storage device 55 is updated so that the set volume of the proximity alarm sound is changed in the travel area where the transmission source vehicle 2 of the received area entry information exists (the travel area specified in the latest S23). (Management update means) The control unit 50 may update the area volume information stored in the storage device 55 by another method based on the specified result of the specified alert target (management-side update unit). For example, the storage device 55 stores the detection frequency of the warning target (the number of detections per predetermined period) in each travel area, and when the control unit 50 is identified as having a warning target (S25: Yes), Based on the specified result, the detection frequency of the travel area is updated, and a proximity alarm set in association with the travel area each time the updated frequency exceeds a plurality of predetermined reference frequencies stepwise. The volume of the sound can be increased by a predetermined level. Conversely, every time the frequency falls below the reference frequency, the volume of the proximity alarm sound set in association with the travel area may be reduced by a predetermined level. However, when the volume setting is increased or decreased, the level is set so as not to exceed the predetermined upper limit value and lower limit value. Thereby, in an area with a high warning level where many warning targets are detected, it is possible to give a sense of vigilance to the surroundings by increasing the volume of the proximity warning sound.
