Abstract

【課題】不必要な車両接近の告知を低減する。
【解決手段】車両10に搭載した制御装置30は、CCDカメラ14とCCDカメラ24とで、歩行者Mの履物16の踵18における下部の後面に設けられたタグ20が認識できたか否かの判定を行うようになっている。この際、タグ20が認識できないと判定した場合には、履物16の踵18の後面が車両10の方向へ向いていないため、歩行者Mは車両10に対して後ろ向きでないと考えられる。この結果、歩行者Mが車両10に気付き易い方向を向いていると判定し、歩行者Mに車両10が接近していることを告知しない。一方、タグ20が認識できたと判定した場合には、歩行者Mが車両10に気付き難い方向を向いていると判定し、歩行者Mに車両10が接近していることを告知する。

An unnecessary vehicle approach notification is reduced.
A control device 30 mounted on a vehicle 10 uses a CCD camera 14 and a CCD camera 24 to determine whether or not a tag 20 provided on the lower rear surface of a heel 18 of a footwear 16 of a pedestrian M can be recognized. Judgment is made. At this time, if it is determined that the tag 20 cannot be recognized, the rear surface of the heel 18 of the footwear 16 does not face the direction of the vehicle 10, so the pedestrian M is considered not facing backward with respect to the vehicle 10. As a result, it is determined that the pedestrian M is facing the direction in which the vehicle 10 is easily noticed, and the pedestrian M is not notified that the vehicle 10 is approaching. On the other hand, when it is determined that the tag 20 can be recognized, it is determined that the pedestrian M is facing a direction in which it is difficult to notice the vehicle 10, and the pedestrian M is notified that the vehicle 10 is approaching.

本発明における車両接近告知装置の第1実施形態を図1〜図5に従って説明する。   1st Embodiment of the vehicle approach notification apparatus in this invention is described according to FIGS.

なお、図中矢印UPは車両上方方向を示し、図中矢印FRは車両前方方向を示している。   In the figure, the arrow UP indicates the upward direction of the vehicle, and the arrow FR in the figure indicates the forward direction of the vehicle.

図1には本発明の第1の実施形態に係る車両接近告知装置を適用した車両(ハイブリッドカー)10が車両斜め前方から見た斜視図によって示されている。   FIG. 1 is a perspective view of a vehicle (hybrid car) 10 to which a vehicle approach notification device according to a first embodiment of the present invention is applied, as viewed obliquely from the front of the vehicle.

図1に示される如く、車両10の前端部に長手方向を車幅方向に沿って配置されたラジエータグリル12の車幅方向中央部には、告知対象向き検出手段としてのCCDカメラ14が設けられている。このCCDカメラ14は、車両10の前方方向を認識するようになっており、車両前方の告知対象としての歩行者Mを認識できるようになっている。   As shown in FIG. 1, a CCD camera 14 is provided as a notification target direction detecting means at a central portion in the vehicle width direction of a radiator grille 12 whose longitudinal direction is arranged at the front end portion of the vehicle 10 along the vehicle width direction. ing. This CCD camera 14 recognizes the front direction of the vehicle 10 and can recognize the pedestrian M as a notification target in front of the vehicle.

図2には歩行者の足元が側面図で示されており、図3には歩行者の足元が後方から見た正面図で示されている。また、図4には歩行者の足元後部が上方から見た平面図で示されている。   FIG. 2 shows a pedestrian's feet in a side view, and FIG. 3 shows a pedestrian's feet in a front view as seen from the rear. FIG. 4 is a plan view of the rear part of the pedestrian's feet as seen from above.

図2に示される如く、歩行者Mの装着物としての左右の履物16の一方の踵18における下部の後面18Aには、被検知部材としてのタグ20が取付けられている。   As shown in FIG. 2, a tag 20 as a member to be detected is attached to the lower rear surface 18 </ b> A of one of the heels 18 of the left and right footwear 16 as a pedestrian M wearing object.

図3に示される如く、タグ20は踵18における下部の後面18Aの水平方向中央に接着等によって固定されている。タグ20は長手方向を水平方向とする長方形状となっており、例えば、CCDカメラ14で検知し易いオレンジ色の反射板で構成されている。   As shown in FIG. 3, the tag 20 is fixed to the horizontal center of the rear surface 18 </ b> A of the lower portion of the collar 18 by bonding or the like. The tag 20 has a rectangular shape whose horizontal direction is the longitudinal direction, and is formed of, for example, an orange reflector that is easily detected by the CCD camera 14.

なお、タグ20の形状は長方形状に限定されず他の形状でもよく、色もオレンジ色に限定されず他の色でもよい。   Note that the shape of the tag 20 is not limited to a rectangular shape, and may be other shapes, and the color is not limited to orange, and may be other colors.

図4に示される如く、履物16の踵18の後面18Aは、円弧状に湾曲しており、タグ20は後面18Aの湾曲面に沿って取付けられている。   As shown in FIG. 4, the rear surface 18A of the heel 18 of the footwear 16 is curved in an arc shape, and the tag 20 is attached along the curved surface of the rear surface 18A.

図1に示される如く、車両10のインナミラー22には、告知対象向き検出手段としてのCCDカメラ24が設けられている。このCCDカメラ24は、車両10の前方方向を認識するようになっており、車両前方の歩行者Mを認識できるようになっている。   As shown in FIG. 1, the inner mirror 22 of the vehicle 10 is provided with a CCD camera 24 as a notification target direction detecting means. The CCD camera 24 recognizes the front direction of the vehicle 10 and can recognize the pedestrian M in front of the vehicle.

CCDカメラ14とCCDカメラ24とは、車両10に搭載された制御手段としての制御装置30に電気的に接続されており、CCDカメラ14とCCDカメラ24からの検出信号が制御装置30に入力されるようになっている。また、制御装置30は車両10に設けられた告知手段としてのスピーカ、クラクション等の発音装置32と、告知手段としてのヘッドランプ等の発光装置34とに電気的に接続されている。なお、制御装置30は車速センサ38にも電気的に接続されており、車速センサ38から車速が制御装置30に入力されるようになっている。   The CCD camera 14 and the CCD camera 24 are electrically connected to a control device 30 as control means mounted on the vehicle 10, and detection signals from the CCD camera 14 and the CCD camera 24 are input to the control device 30. It has become so. The control device 30 is electrically connected to a sound generation device 32 such as a speaker or a horn provided as a notification means provided in the vehicle 10 and a light emitting device 34 such as a headlamp as a notification means. The control device 30 is also electrically connected to the vehicle speed sensor 38, and the vehicle speed is input from the vehicle speed sensor 38 to the control device 30.

従って、制御装置30は、CCDカメラ14とCCDカメラ24からの検出信号と車速センサ38からの検出信号とに基づいて、発音装置32と発光装置34とを制御できるようになっている。   Therefore, the control device 30 can control the sound producing device 32 and the light emitting device 34 based on the detection signals from the CCD camera 14 and the CCD camera 24 and the detection signal from the vehicle speed sensor 38.

次に、本実施形態の作用を図5のフローチャートに従って説明する。   Next, the operation of the present embodiment will be described with reference to the flowchart of FIG.

図5に示される如く、制御装置30ではステップ(以下、Sと記載する)100において、車速センサ38からの検出信号に基づいて、車両10が走行中であるか否か判定する。なお、シフトレバーの位置等から車両10が前進中であるか否かを判定するようになっている。   As shown in FIG. 5, the control device 30 determines whether or not the vehicle 10 is traveling based on a detection signal from the vehicle speed sensor 38 in step (hereinafter referred to as S) 100. Whether the vehicle 10 is moving forward is determined from the position of the shift lever or the like.

S100において、車両10が走行中(前進中)であると判定すると、制御装置30はS102において、CCDカメラ14とCCDカメラ24からの検出信号に基づいて、車両前方の歩行者Mが車両10に気付き難い方向に向いているか否かの判定を行う。   If it is determined in S100 that the vehicle 10 is traveling (advancing), the control device 30 causes the pedestrian M in front of the vehicle to move to the vehicle 10 based on detection signals from the CCD camera 14 and the CCD camera 24 in S102. It is determined whether or not it is in a direction that is difficult to notice.

即ち、制御装置30はCCDカメラ14とCCDカメラ24からの検出信号に、歩行者Mの履物16の踵18における下部の後面18Aに設けられたタグ20があるか否かの判定を行う。   That is, the control device 30 determines whether or not the detection signal from the CCD camera 14 and the CCD camera 24 includes the tag 20 provided on the lower rear surface 18A of the heel 18 of the footwear 16 of the pedestrian M.

この際、歩行者Mの履物16の踵18における下部の後面18Aに設けられたタグ20があると判定した場合には、履物16が車両10の進行方向へ向いているため、歩行者Mも車両10の進行方向へ向いている(車両10に対して後ろ向き)と考えられる。この結果、歩行者Mが車両10に気付き難い方向に向いており、車両10が歩行者Mが目視し難い位置(歩行者Mの後方)にあると判定する。   At this time, if it is determined that there is a tag 20 provided on the lower rear surface 18A of the heel 18 of the footwear 16 of the pedestrian M, since the footwear 16 is directed in the traveling direction of the vehicle 10, the pedestrian M also It is considered that the vehicle 10 faces in the traveling direction (facing backward with respect to the vehicle 10). As a result, it is determined that the pedestrian M is facing the direction in which the vehicle 10 is difficult to notice, and the vehicle 10 is in a position where the pedestrian M is difficult to see (behind the pedestrian M).

S102において、車両前方の歩行者Mが車両10に気付き難い方向にあると判定すると、制御装置30は、S104において、歩行者Mに車両10が接近していることを告知する。   In S102, when it is determined that the pedestrian M in front of the vehicle is in a direction in which it is difficult to notice the vehicle 10, the control device 30 notifies the pedestrian M that the vehicle 10 is approaching in S104.

具体的には、制御装置30から発音装置32又は発光装置34に制御信号を出力して、発音装置32から告知音を発生する、又は、発光装置34から告知光を発生することで、歩行者Mに車両10の接近を告知する。   Specifically, the control device 30 outputs a control signal to the sounding device 32 or the light emitting device 34 to generate a notification sound from the sounding device 32 or generate a notification light from the light emitting device 34, so that a pedestrian Inform M that the vehicle 10 is approaching.

一方、S102において、歩行者Mの履物16の踵18における下部の後面18Aに設けられたタグ20がないと判定した場合には、履物16が車両10の進行方向へ向いていないため、歩行者Mは車両10の方向、又は、車両10の進行方向に対して横方向へ向いていると考えられる。この結果、車両10は歩行者Mが目視し易い位置(歩行者Mの前方又は側方)にあり、歩行者Mが車両10に気付き易い方向に向いている判定する。   On the other hand, if it is determined in S102 that there is no tag 20 provided on the lower rear surface 18A of the heel 18 of the footwear 16 of the pedestrian M, since the footwear 16 is not directed in the traveling direction of the vehicle 10, the pedestrian M is considered to be directed in the lateral direction with respect to the direction of the vehicle 10 or the traveling direction of the vehicle 10. As a result, it is determined that the vehicle 10 is in a position (a front side or a side of the pedestrian M) that is easy for the pedestrian M to view, and is oriented in a direction in which the pedestrian M easily notices the vehicle 10.

S102において、車両前方の歩行者Mが車両10に気付き易い方向に向いていると判定すると、制御装置30は、S104の処理を行わない。即ち、歩行者Mに車両10が接近していることを告知しない。   If it is determined in S102 that the pedestrian M ahead of the vehicle is facing the direction in which the vehicle 10 is easily noticed, the control device 30 does not perform the process of S104. That is, the pedestrian M is not notified that the vehicle 10 is approaching.

従って、本実施形態では、歩行者Mに対して不必要な車両接近の告知を低減することができる。   Therefore, in the present embodiment, unnecessary notification of approaching the vehicle to the pedestrian M can be reduced.

また、本実施形態では、タグ20を歩行者Mの履物16の踵18に設けることで、CCDカメラ14とCCDカメラ24によって歩行者Mの履物16の踵18の位置を容易に検知できる。このため、構成が簡単なCCDカメラ14、CCDカメラ24によって車両接近の告知精度を向上できる。   In the present embodiment, the tag 20 is provided on the heel 18 of the footwear 16 of the pedestrian M so that the CCD camera 14 and the CCD camera 24 can easily detect the position of the heel 18 of the footwear 16 of the pedestrian M. For this reason, the accuracy of notification of approaching the vehicle can be improved by the CCD camera 14 and the CCD camera 24 having a simple configuration.

次に、本発明における車両接近告知装置の第2実施形態を図6〜図8に従って説明する。   Next, 2nd Embodiment of the vehicle approach notification apparatus in this invention is described according to FIGS.

なお、第1実施形態と同一部材に付いては、同一符号を付してその説明を省略する。   In addition, about the same member as 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

図6には歩行者の足元が後方から見た正面図で示されており、図7には歩行者の足元後部が上方から見た平面図で示されている。   FIG. 6 shows a pedestrian's feet as seen from the front, and FIG. 7 shows a pedestrian's feet as a plan as seen from above.

図6に示される如く、本実施形態では、歩行者Mの履物16の踵18における下部の後面18Aに、被検知部材としての2枚のタグ20が取付けられている。これらのタグ20は踵18における下部の後面18Aの左右方向両端部18Bに接着等によって固定されている。   As shown in FIG. 6, in the present embodiment, two tags 20 as detection members are attached to the lower rear surface 18 </ b> A of the heel 18 of the footwear 16 of the pedestrian M. These tags 20 are fixed to the left and right end portions 18B of the rear surface 18A of the lower portion of the collar 18 by bonding or the like.

図7に示される如く、履物16の踵18における下部の後面18Aは、円弧状に湾曲しており、2枚のタグ20は後面18Aの湾曲面に沿って取付けられている。   As shown in FIG. 7, the lower rear surface 18A of the foot 18 of the footwear 16 is curved in an arc shape, and the two tags 20 are attached along the curved surface of the rear surface 18A.

従って、履物16が車両10の進行方向に向いている場合には、CCDカメラ14又はCCDカメラ24で2枚のタグ20が認識され、履物16が車両の進行方向に対して斜め方向へ向いている場合には、CCDカメラ14又はCCDカメラ24で一方のタグ20のみが認識されるようになっている。   Accordingly, when the footwear 16 is oriented in the traveling direction of the vehicle 10, the two tags 20 are recognized by the CCD camera 14 or the CCD camera 24, and the footwear 16 is directed obliquely with respect to the traveling direction of the vehicle. In the case of being present, only one tag 20 is recognized by the CCD camera 14 or the CCD camera 24.

次に、本実施形態の作用を図8のフローチャートに従って説明する。   Next, the operation of the present embodiment will be described with reference to the flowchart of FIG.

図8に示される如く、S100、S102は第1実施形態と同様のため、説明を省略する。   As shown in FIG. 8, S100 and S102 are the same as those in the first embodiment, and a description thereof will be omitted.

S102において、歩行者Mの履物16の踵18における下部の後面18Aに設けられたタグ20があると判定した場合には、S200において、2枚のタグ20があるか否かの判定を行う。   If it is determined in S102 that there is a tag 20 provided on the lower rear surface 18A of the heel 18 of the footwear 16 of the pedestrian M, it is determined in S200 whether there are two tags 20 or not.

S200において、2枚のタグ20があると判定した場合には、履物16が車両10の進行方向に向いているため、歩行者Mは車両10に対して後ろ向きと考えられる。この結果、車両10は歩行者Mが目視し難い位置にあり、歩行者Mが車両10に気付き難い方向を向いていると判定する。   In S <b> 200, when it is determined that there are two tags 20, the pedestrian M is considered to face backward with respect to the vehicle 10 because the footwear 16 faces the traveling direction of the vehicle 10. As a result, it is determined that the vehicle 10 is in a position that is difficult for the pedestrian M to see and the pedestrian M is facing a direction in which the vehicle 10 is difficult to notice.

このため、制御装置30は、S202において、歩行者Mの車両10が接近していることを告知する。   For this reason, the control apparatus 30 notifies that the vehicle 10 of the pedestrian M is approaching in S202.

具体的には、制御装置30から発音装置32又は発光装置34に制御信号を出力して、発音装置32から告知音を発生する、又は、発光装置34から告知光を発生することで、歩行者Mに車両10の接近を告知する。   Specifically, the control device 30 outputs a control signal to the sounding device 32 or the light emitting device 34 to generate a notification sound from the sounding device 32 or generate a notification light from the light emitting device 34, so that a pedestrian Inform M that the vehicle 10 is approaching.

一方、S200において、2枚のタグ20がないと判定した場合、即ち、1枚のタグ20のみがあると判定した場合には、履物16が車両10の進行方向に対して斜め前方向へ向いているため、歩行者Mは車両10に対して斜め後ろ向きと考えられる。この結果、車両10は歩行者Mが、やや目視し難い位置にあり、歩行者Mが車両10にやや気付き難い方向を向いていると判定する。   On the other hand, when it is determined in S200 that there are no two tags 20, that is, when it is determined that there is only one tag 20, the footwear 16 faces obliquely forward with respect to the traveling direction of the vehicle 10. Therefore, the pedestrian M is considered to be obliquely rearward with respect to the vehicle 10. As a result, the vehicle 10 is determined to be in a position where the pedestrian M is slightly difficult to see, and the pedestrian M is facing the direction in which the vehicle 10 is slightly difficult to notice.

このため、制御装置30は、S204において、車両10の接近の告知をS202の処理に比べて軽減する。   For this reason, the control apparatus 30 reduces the notification of the approach of the vehicle 10 compared with the process of S202 in S204.

即ち、制御装置30から発音装置32又は発光装置34に告知を軽減する制御信号を出力して、発音装置32からS202で発生した告知音より小さな音を発生する、又は、発光装置34からS202で発生した告知光より弱い光を発生することで、歩行者Mに車両10の接近を告知する。   That is, a control signal for reducing the notification is output from the control device 30 to the sound generation device 32 or the light emitting device 34 to generate a sound smaller than the notification sound generated in S202 from the sound generation device 32 or from the light emission device 34 to S202. The pedestrian M is notified of the approach of the vehicle 10 by generating light that is weaker than the generated notification light.

従って、本実施形態では、歩行者Mの向きによって、告知音の大きさや告知光の強さ(明るさ)を変えるため、歩行者Mに対して不必要に大きすぎる音や強すぎる光で車両接近を告知することがない。この結果、不必要な車両接近の告知を更に低減することができる。   Therefore, in this embodiment, since the size of the notification sound and the intensity (brightness) of the notification light are changed depending on the direction of the pedestrian M, the vehicle is generated with excessively loud sound or too strong light for the pedestrian M. There is no notification of approach. As a result, unnecessary notification of vehicle approach can be further reduced.

なお、履物16の踵18に取付けるタグ20の数は2枚に限定されず、3枚以上とし、検知されるタグ20の枚数によって、歩行者Mが車両10に更に気付き難い方向を向いているか否かを判定してもよい。   It should be noted that the number of tags 20 attached to the heel 18 of the footwear 16 is not limited to two, but is set to three or more, and depending on the number of tags 20 detected, whether the pedestrian M faces a direction that is more difficult to notice the vehicle 10. It may be determined whether or not.

また、踵18における下部の後面18Aの水平方向両端部18Bに跨る長尺状の1枚のタグ20を使用して、検知されるタグ20の長さによって、歩行者Mが車両10に気付き難い方向を向いているか否かを判定してもよい。   Moreover, the pedestrian M is hard to notice the vehicle 10 by the length of the tag 20 detected using the long tag 20 straddling the horizontal direction both ends 18B of the lower rear surface 18A of the saddle 18. You may determine whether it is facing the direction.

次に、本発明における車両接近告知装置の第3実施形態を図9及び図10に従って説明する。   Next, a third embodiment of the vehicle approach notification device according to the present invention will be described with reference to FIGS.

なお、第1実施形態と同一部材に付いては、同一符号を付してその説明を省略する。   In addition, about the same member as 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

図9には歩行者の足元が後方から見た正面図で示されている。   FIG. 9 shows a pedestrian's feet as viewed from the front.

図9に示される如く、本実施形態では、歩行者Mの履物16の踵18における下部の後面18Aには、被検知部材としてのタグ40が取付けられている。タグ40は踵18における下部の後面18Aの水平方向中央に接着等によって固定されている。タグ40は円形状となっている。   As shown in FIG. 9, in this embodiment, a tag 40 as a detected member is attached to the lower rear surface 18A of the heel 18 of the footwear 16 of the pedestrian M. The tag 40 is fixed to the center in the horizontal direction of the lower rear surface 18A of the collar 18 by bonding or the like. The tag 40 has a circular shape.

また、円形のタグ40は、このタグ40が取付けられた履物16を履いている歩行者Mに聴覚の傷害があるという歩行者情報を示しており、第1実施形態に示す長方形状のタグ20が取付けられた履物16を履いている聴覚に傷害がない歩行者と区別している。   The circular tag 40 indicates pedestrian information indicating that the pedestrian M wearing the footwear 16 to which the tag 40 is attached has an auditory injury, and the rectangular tag 20 shown in the first embodiment. Is distinguished from a pedestrian who wears the footwear 16 to which is attached.

次に、本実施形態の作用を図10のフローチャートに従って説明する。   Next, the operation of the present embodiment will be described with reference to the flowchart of FIG.

図10に示される如く、S100、S102は第1実施形態と同様のため、説明を省略する。   As shown in FIG. 10, S100 and S102 are the same as those in the first embodiment, and a description thereof will be omitted.

S102において、歩行者Mの履物16の踵18における下部の後面18Aに設けられたタグ20又はタグ40があると判定した場合には、S300において、認識されているタグの形状が円形か否かの判定を行う。   If it is determined in S102 that there is a tag 20 or a tag 40 provided on the lower rear surface 18A of the heel 18 of the footwear 16 of the pedestrian M, whether or not the recognized tag shape is circular in S300. Judgment is made.

S300において、タグの形状が円形でない、即ち、長方形のタグ20と判定した場合には、履物16を履いている歩行者Mは聴覚に傷害がないと考えられる。このため、聴覚に傷害がない歩行者Mが、車両10を目視し難い方向に向いていると判定する。   In S300, if it is determined that the tag shape is not circular, that is, the rectangular tag 20, the pedestrian M wearing the footwear 16 is considered to have no hearing damage. For this reason, it is determined that the pedestrian M who has no hearing damage is facing the direction in which the vehicle 10 is difficult to see.

このため、制御装置30は、S302において、歩行者Mに車両10が接近していることを告知する。   Therefore, the control device 30 notifies the pedestrian M that the vehicle 10 is approaching in S302.

具体的には、制御装置30から発音装置32に制御信号を出力して、発音装置32から告知音を発生することで、歩行者Mに車両10の接近を告知する。   Specifically, the control device 30 outputs a control signal to the sound generation device 32 and generates a notification sound from the sound generation device 32 to notify the pedestrian M of the approach of the vehicle 10.

一方、S300において、円形のタグ40と判定された場合には、履物16を履いている歩行者Mは聴覚に傷害があると考えられる。この結果、聴覚に傷害がある歩行者Mが、車両10に気付き難い方向を向いていると判定する。   On the other hand, when it is determined in S300 that the tag is a circular tag 40, it is considered that the pedestrian M wearing the footwear 16 is injured in hearing. As a result, it is determined that the pedestrian M with hearing damage is facing a direction in which the vehicle 10 is difficult to notice.

このため、制御装置30は、S304において、発光装置34に制御信号を出力して、発光装置34から告知光を発生することで、歩行者Mに車両10の接近を告知する。   For this reason, in S304, the control device 30 outputs a control signal to the light emitting device 34 and generates notification light from the light emitting device 34, thereby notifying the pedestrian M of the approach of the vehicle 10.

従って、本実施形態では、聴覚に傷害のある歩行者Mには告知光によって車両10の接近を告知する。このため、歩行者Mに合った(歩行者Mが気付き易い)告知方法によって車両10の接近を告知することができる。この結果、歩行者Mが車両接近の告知に気付き易くなる。   Therefore, in this embodiment, the approach of the vehicle 10 is notified to the pedestrian M with hearing damage by the notification light. For this reason, the approach of the vehicle 10 can be notified by the notification method suitable for the pedestrian M (the pedestrian M is easy to notice). As a result, it becomes easier for the pedestrian M to notice the approach of the vehicle.

なお、タグ20、40の形状を変えることによって、聴覚傷害以外の歩行者情報(告知対象情報)、例えば、高齢者や子供等の他の歩行者情報を示し、これらの歩行者情報に基づいて告知音の大小、高低等を変えてもよい。   By changing the shape of the tags 20 and 40, pedestrian information other than hearing injury (notification target information), for example, other pedestrian information such as an elderly person or a child is shown, and based on these pedestrian information. You may change the size, height, etc. of the notification sound.

また、タグ20、40の形状に代えて、バーコード等によって歩行者情報を示し、これらの歩行者情報に基づいて、告知方法を変える構成としてもよい。   Moreover, it is good also as a structure which replaces with the shape of the tags 20 and 40, shows pedestrian information with a barcode etc., and changes a notification method based on these pedestrian information.

次に、本発明における車両接近告知装置の第4実施形態を図11に従って説明する。   Next, a fourth embodiment of the vehicle approach notification device according to the present invention will be described with reference to FIG.

なお、第1実施形態と同一部材に付いては、同一符号を付してその説明を省略する。   In addition, about the same member as 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

本実施形態では、顔認識手段としてのCCDカメラ14又はCCDカメラ24の少なくとも一方で認識した歩行者Mの顔と、タグ20の検知とを組み合わせることで、歩行者Mが車両10に気付き難い方向を向いているか否かの検知精度を向上できるようになっている。   In the present embodiment, a direction in which the pedestrian M hardly notices the vehicle 10 by combining the face of the pedestrian M recognized by at least one of the CCD camera 14 or the CCD camera 24 as the face recognition unit and the detection of the tag 20. It is possible to improve the detection accuracy of whether or not it is facing.

次に、本実施形態の作用を図11のフローチャートに従って説明する。   Next, the operation of the present embodiment will be described with reference to the flowchart of FIG.

図11に示される如く、S100、S102は第1実施形態と同様のため、説明を省略する。   As shown in FIG. 11, S100 and S102 are the same as those in the first embodiment, and a description thereof will be omitted.

S102において、歩行者Mの履物16の踵18における下部の後面18Aに設けられたタグ20があると判定した場合には、S400において、CCDカメラ14又はCCDカメラ24の検出信号から歩行者Mの顔を認識できたか否かの判定を行う。   In S102, when it is determined that there is the tag 20 provided on the lower rear surface 18A of the heel 18 of the footwear 16 of the pedestrian M, the detection signal of the pedestrian M is detected from the detection signal of the CCD camera 14 or the CCD camera 24 in S400. It is determined whether or not the face can be recognized.

S400において、歩行者Mの顔が認識できないと判定した場合、即ち、履物16を履いている歩行者Mが車両10の方向に向いていないため、CCDカメラ14又はCCDカメラ24の検出信号から歩行者Mの顔が認識できないと考えられる。この結果、歩行者Mが車両10に気付き難い方向を向いていると判定する。   In S400, when it is determined that the face of the pedestrian M cannot be recognized, that is, since the pedestrian M wearing the footwear 16 is not facing the direction of the vehicle 10, the walking from the detection signal of the CCD camera 14 or the CCD camera 24 is performed. It is considered that the face of the person M cannot be recognized. As a result, it is determined that the pedestrian M is facing a direction in which the vehicle 10 is difficult to notice.

このため、制御装置30は、S402において、歩行者Mに車両10が接近していることを告知する。   Therefore, the control device 30 notifies the pedestrian M that the vehicle 10 is approaching in S402.

具体的には、制御装置30から発音装置32又は発光装置34に制御信号を出力して、発音装置32から告知音を発生する、又は、発光装置34から告知光を発生することで、歩行者Mに車両10の接近を告知する。   Specifically, the control device 30 outputs a control signal to the sounding device 32 or the light emitting device 34 to generate a notification sound from the sounding device 32 or generate a notification light from the light emitting device 34, so that a pedestrian Inform M that the vehicle 10 is approaching.

一方、S400において、歩行者Mの顔を認識できると判定した場合、即ち、歩行者Mが車両10の方向に向いていると考えられる場合には、歩行者Mが車両10に気付き易い方向を向いていると判定する。   On the other hand, if it is determined in S400 that the face of the pedestrian M can be recognized, that is, if it is considered that the pedestrian M is facing the direction of the vehicle 10, the direction in which the pedestrian M is likely to notice the vehicle 10 is determined. It is determined that it is suitable.

このため、制御装置30は歩行者Mに車両10が接近していることを告知しない。   For this reason, the control device 30 does not notify the pedestrian M that the vehicle 10 is approaching.

従って、本実施形態では、CCDカメラ14又はCCDカメラ24の少なくとも一方で認識した歩行者Mの顔と、タグ20の検知とを組み合わせることで、歩行者Mが車両10を確認し難い方向に向いているか否かの判定精度を向上できる。   Therefore, in the present embodiment, by combining the face of the pedestrian M recognized by at least one of the CCD camera 14 or the CCD camera 24 and the detection of the tag 20, the pedestrian M faces in a direction in which it is difficult to confirm the vehicle 10. It is possible to improve the accuracy of determining whether or not the
