The lamp control unit 5 is an example of a control unit. A low beam lamp unit 2, a high beam lamp unit 3, and a road surface drawing lamp 4 are connected to the lamp control unit 5. Further, the bank angle sensor 6, the external sensor 7, the speed sensor 8, and the like are electrically connected to the lamp control unit 5. The bank angle sensor 6 detects the tilted state of the motorcycle 100. The external sensor 7 detects environmental information outside the vehicle such as an object. The speed sensor 8 detects the speed of the motorcycle 100. Note that FIG. 2 is a block diagram when the headlamp 1 integrally includes the road surface drawing lamp 4, but the lamp control unit 5 controls the road surface drawing lamp 4 even when the road surface drawing lamp 4 is a separate member. You may. Each of the sensors 6 to 8 may also be provided as a separate member different from the headlamp 1.

　バンク角センサ６、外部センサ７および速度センサ８によって検出された各情報は、ランプ制御部５へ送信される。ランプ制御部５は、各センサ６～８から送信されてきた情報に基づいて、ロービーム灯具ユニット２、ハイビーム灯具ユニット３および路面描画ランプ４を制御する。例えば、ランプ制御部５は、各センサ６～８の検出結果に基づいてヘッドランプ１（ロービーム灯具ユニット２、ハイビーム灯具ユニット３および路面描画ランプ４）を制御し、車両前方に形成される配光パターン（ロービーム配光パターン、ハイビーム配光パターンおよび路面描画配光パターン）を調整することが可能である。 Each information detected by the bank angle sensor 6, the external sensor 7, and the speed sensor 8 is transmitted to the lamp control unit 5. The lamp control unit 5 controls the low beam lamp unit 2, the high beam lamp unit 3, and the road surface drawing lamp 4 based on the information transmitted from the sensors 6 to 8. For example, the lamp control unit 5 controls the headlamp 1 (low beam lamp unit 2, high beam lamp unit 3 and road surface drawing lamp 4) based on the detection results of the sensors 6 to 8, and the light distribution formed in front of the vehicle. It is possible to adjust the patterns (low beam light distribution pattern, high beam light distribution pattern and road surface drawing light distribution pattern).
　図３は、ヘッドランプ１が備えるハイビーム灯具ユニット３の概略構成を示す垂直断面図である。図３に示すように、ヘッドランプ１は、車両前方側に開口部を有するランプボディ１１と、ランプボディ１１の開口部を覆うように取り付けられた透明の前面カバー１２とを備えている。ランプボディ１１と前面カバー１２とによって灯室１３が形成される。灯室１３の内部に、ハイビーム灯具ユニット３が配置され、灯室１３の外部にランプ制御部５、バンク角センサ６、および外部センサ（例えばＬｉＤＡＲ）７等が配置されている。図３の断面図では図示されていないが、ロービーム灯具ユニット２はハイビーム灯具ユニット３と同様にヘッドランプ１の灯室１３の内部に収容されている。路面描画ランプ４は灯室１３の外部に配置されている。 FIG. 3 is a vertical cross-sectional view showing a schematic configuration of the high beam lamp unit 3 included in the headlamp 1.

　ハイビーム灯具ユニット３は、いわゆるプロジェクタ型の灯具である。ハイビーム灯具ユニット３は、投影レンズ３１と、光源ユニット３２と、ホルダ３４とを備えている。光源ユニット３２は、ハイビームの光源３３を有する。ホルダ３４は、投影レンズ３１および光源ユニット３２を保持する。投影レンズ３１は、前方側表面が凸面で後方側表面が平面の平凸非球面レンズであり、車両前後方向に延びる光軸Ａｘ上に配置されている。投影レンズ３１は、その周縁部がホルダ３４の前端側に保持されている。投影レンズ３１は、光源３３からの光を灯具前方へ照射して所定のハイビーム配光パターンを形成する。 The high beam lamp unit 3 is a so-called projector type lamp.

　次に本開示のヘッドランプ１及び車両運転支援システムを、図５から図７を参照して説明する。
　（第一実施例） Next, the headlamp 1 and the vehicle driving support system of the present disclosure will be described with reference to FIGS. 5 to 7.
(First Example)
　図５は、自動二輪車１００が交差点を直進する場合であって、自動二輪車１００に対向する対象物が当該交差点で右折する状況を示す概要図を示す。図５は、対象物の一例である右折する対向車ＣＶを示している。対向車ＣＶは例えば四輪車である。対象物は、右折する四輪車に限られず、左折する対向車、前走車でもよいし、二輪車でもよい。 FIG. 5 shows a schematic diagram showing a situation in which the motorcycle 100 goes straight through an intersection and an object facing the motorcycle 100 turns right at the intersection. FIG. 5 shows an oncoming vehicle CV turning right, which is an example of an object. The oncoming vehicle CV is, for example, a four-wheeled vehicle. The object is not limited to a four-wheeled vehicle that turns right, but may be an oncoming vehicle that turns left, a vehicle in front, or a two-wheeled vehicle.
　図５のように対向車ＣＶの運転者は交差点で右折する場合に、自動二輪車１００を認知して、対向車ＣＶと自動二輪車１００との接触事故を防ぐように注意して運転することが好ましい。しかしながら、一般的に自動二輪車１００の車体は四輪車に比べて小さいため、対向車ＣＶの運転者は、車体の小さい自動二輪車１００を認知せず、見落としてしまうことがある。特に様々な大きさの車両が複数行き交っている交差点においては、対向車ＣＶの運転者から車体の小さい自動二輪車１００は認知されにくい。 As shown in FIG. 5, when turning right at an intersection, it is preferable that the driver of the oncoming vehicle CV recognizes the motorcycle 100 and drives carefully so as to prevent a contact accident between the oncoming vehicle CV and the motorcycle 100. .. However, since the body of the motorcycle 100 is generally smaller than that of the four-wheeled vehicle, the driver of the oncoming vehicle CV may not recognize the motorcycle 100 having a small body and may overlook it. Especially at an intersection where a plurality of vehicles of various sizes come and go, it is difficult for the driver of the oncoming vehicle CV to recognize the motorcycle 100 having a small body.
　そこで本開示のランプ制御部５は、ハイビーム灯具ユニット３を駆動するとともに、外部センサ７によって検出された検出結果に基づいて、自動二輪車１００の車体と対象物である対向車ＣＶとが互いに接触する接触予測値を算出し、算出した当該接触予測値の大小を判断するように構成されている。外部センサ７が対向車ＣＶを検出した場合であって、接触予測値が所定の閾値を超えたとランプ制御部５が判断した場合には、ランプ制御部５は光の照射態様（モード）を変更するようにハイビーム灯具ユニット３を駆動するように構成されている。 Therefore, the lamp control unit 5 of the present disclosure drives the high beam lamp unit 3, and based on the detection result detected by the external sensor 7, the vehicle body of the motorcycle 100 and the oncoming vehicle CV, which is an object, come into contact with each other. It is configured to calculate the contact prediction value and determine the magnitude of the calculated contact prediction value. When the external sensor 7 detects the oncoming vehicle CV and the lamp control unit 5 determines that the contact prediction value exceeds a predetermined threshold value, the lamp control unit 5 changes the light irradiation mode. It is configured to drive the high beam lamp unit 3 so as to do so.
　接触予測値は、自動二輪車１００の車体と対象物（対向車ＣＶ）とが互いに接触する可能性を数値化した値である。本開示において、外部センサ７は、自動二輪車１００から対向車ＣＶまでの距離や角度、灯具前方からの所定位置、例えば灯具前方２５ｍの位置に配置された仮想鉛直スクリーン上における対向車ＣＶの角度座標などを検出する。例えば自動二輪車１００の車体と対向車ＣＶとの間の距離が所定距離よりも短くなった場合に、ランプ制御部５は高い接触予測値を算出してもよい。また自動二輪車１００の車体と自動二輪車１００の側方から来る車両ＣＶ２とが、各々一定速度で互いに近づく場合、自動二輪車１００の車体と側方から来る車両ＣＶ２との互いの相対角度が一定である状態が所定時間継続される。図６は、自動二輪車１００が交差点を直進する場合であって、自動二輪車１００の左側から車両ＣＶ２が当該交差点を直進する状況を示す概要図を示す。このような場合も、ランプ制御部５は高い接触予測値を算出してもよい。 The contact prediction value is a numerical value of the possibility that the vehicle body of the motorcycle 100 and the object (oncoming vehicle CV) come into contact with each other. In the present disclosure, the external sensor 7 refers to the distance and angle from the motorcycle 100 to the oncoming vehicle CV, and the angular coordinates of the oncoming vehicle CV on a virtual vertical screen arranged at a predetermined position from the front of the lighting equipment, for example, 25 m in front of the lighting equipment. Etc. are detected. For example, when the distance between the vehicle body of the motorcycle 100 and the oncoming vehicle CV becomes shorter than a predetermined distance, the lamp control unit 5 may calculate a high contact prediction value. Further, when the body of the motorcycle 100 and the vehicle CV2 coming from the side of the motorcycle 100 approach each other at a constant speed, the relative angle between the body of the motorcycle 100 and the vehicle CV2 coming from the side is constant. The state continues for a predetermined time. FIG. 6 shows a schematic diagram showing a situation in which the motorcycle 100 goes straight through an intersection and the vehicle CV2 goes straight through the intersection from the left side of the motorcycle 100. Even in such a case, the lamp control unit 5 may calculate a high contact prediction value.
　ランプ制御部５は接触予測値の大小を判断することで、自動二輪車１００の車体と対向車ＣＶとが互いに接触する可能性を判断する。特に接触予測値が所定の閾値を超えたとランプ制御部５が判断した場合には、接触事故を防ぐように、対向車ＣＶの運転者に対して注意を喚起する必要がある。本開示では、接触予測値が所定の閾値を超えた場合にハイビーム灯具ユニット３の光の照射態様が変更されるため、対向車ＣＶの運転者は光の照射態様の変更を通じて、接触事故の可能性を認知することができる。 The lamp control unit 5 determines the possibility that the vehicle body of the motorcycle 100 and the oncoming vehicle CV come into contact with each other by determining the magnitude of the predicted contact value. In particular, when the lamp control unit 5 determines that the contact prediction value exceeds a predetermined threshold value, it is necessary to call attention to the driver of the oncoming vehicle CV so as to prevent a contact accident. In the present disclosure, since the light irradiation mode of the high beam lamp unit 3 is changed when the contact prediction value exceeds a predetermined threshold value, the driver of the oncoming vehicle CV can have a contact accident by changing the light irradiation mode. Can recognize sex.
　接触事故を防止するためには、短時間ですぐに対向車ＣＶの運転者に注意喚起することが好ましい。注意喚起の一つの方法として、ハイビーム灯具ユニット３を点灯することで自動二輪車１００の車体の存在を対向車ＣＶの運転者に対して示す方法がある。しかしながら、ハイビーム灯具ユニット３の点灯を継続するだけで、照射態様の変化がない場合では、当該点灯は自動二輪車１００の車体の存在を示すだけであり、対向車ＣＶの運転者は接触事故の可能性に気づかない可能性がある。これに対し本開示によれば、光の照射態様を変更することで、対向車ＣＶの運転者は、短い時間内であっても照射態様の変化を通じて接触事故の可能性を認知することができる。そのため本開示は対向車ＣＶの運転者に対して安全運転を促して、接触事故を抑制することができる。 In order to prevent a contact accident, it is preferable to immediately alert the driver of the oncoming vehicle CV in a short time. As one method of calling attention, there is a method of indicating the existence of the vehicle body of the motorcycle 100 to the driver of the oncoming vehicle CV by turning on the high beam lamp unit 3. However, if the high beam lamp unit 3 is only continuously lit and there is no change in the irradiation mode, the lighting only indicates the presence of the vehicle body of the motorcycle 100, and the driver of the oncoming vehicle CV may have a contact accident. You may not notice the sex. On the other hand, according to the present disclosure, by changing the light irradiation mode, the driver of the oncoming vehicle CV can recognize the possibility of a contact accident through the change in the irradiation mode even within a short time. .. Therefore, the present disclosure can encourage the driver of the oncoming vehicle CV to drive safely and suppress a contact accident.
　接触予測値の閾値は、複数設けられても良い。本開示では、自動二輪車１００と対向車ＣＶとが互いに接触する可能性が高くはないものの対向車ＣＶに対して注意喚起が必要な場合として第一の閾値と、自動二輪車１００と対向車ＣＶとが互いに接触する可能性が高い場合として、第一の閾値より大きい第二の閾値とを設ける。接触予測値が第一の閾値を超えたとランプ制御部５が判断した場合、ランプ制御部５は第一の照射態様でハイビーム灯具ユニット３を駆動する。接触予測値が第二の閾値を超えたとランプ制御部５が判断した場合、ランプ制御部５は第一の照射態様とは異なる第二の照射態様でハイビーム灯具ユニット３を駆動する。 A plurality of thresholds for the contact prediction value may be provided. In the present disclosure, the first threshold value and the motorcycle 100 and the oncoming vehicle CV are defined as a case where the motorcycle 100 and the oncoming vehicle CV are not likely to come into contact with each other, but it is necessary to call attention to the oncoming vehicle CV. A second threshold value larger than the first threshold value is provided as a case where the two are likely to come into contact with each other. When the lamp control unit 5 determines that the contact predicted value exceeds the first threshold value, the lamp control unit 5 drives the high beam lamp unit 3 in the first irradiation mode. When the lamp control unit 5 determines that the contact predicted value exceeds the second threshold value, the lamp control unit 5 drives the high beam lamp unit 3 in a second irradiation mode different from the first irradiation mode.
　本開示によれば、第一の閾値及び第二の閾値を用いることで、ランプ制御部５は接触予測値の高低（レベル）を複数の段階に分けて判断することができる。接触予測値の高低（レベル）を複数の照射態様によって使い分けることで、対向車ＣＶの運転者に対して、より高い精度で接触事故の可能性の有無または程度を示すことができる。その結果、運転者に対して安全運転を促し、接触事故を抑制することができる。 According to the present disclosure, by using the first threshold value and the second threshold value, the lamp control unit 5 can determine the level of the contact prediction value by dividing it into a plurality of stages. By properly using the high and low (level) of the contact prediction value according to a plurality of irradiation modes, it is possible to indicate to the driver of the oncoming vehicle CV whether or not there is a possibility of a contact accident or the degree of the contact accident with higher accuracy. As a result, it is possible to encourage the driver to drive safely and suppress contact accidents.
　光の照射態様の変更、あるいは第一の照射態様から第二の照射態様への変更は、照射方向の変更を含む。 The change in the light irradiation mode, or the change from the first irradiation mode to the second irradiation mode, includes a change in the irradiation direction.
　具体的には、第一の照射態様における光の照射方向は、第二の照射態様における光の照射方向と異なる。本開示では、自動二輪車１００の車体から路面に向かって照射される光の照射方向を第一の方向、車体から対向車ＣＶに向かって照射される光の照射方向を第二の方向とする。接触予測値の高低（レベル）を、複数の照射方向によって使い分けることで、対向車ＣＶの運転者に対して、高い精度で接触事故の可能性の有無または程度を示すことができる。 Specifically, the light irradiation direction in the first irradiation mode is different from the light irradiation direction in the second irradiation mode. In the present disclosure, the irradiation direction of the light emitted from the vehicle body of the motorcycle 100 toward the road surface is the first direction, and the irradiation direction of the light emitted from the vehicle body toward the oncoming vehicle CV is the second direction. By properly using the high and low (level) of the contact prediction value according to a plurality of irradiation directions, it is possible to indicate to the driver of the oncoming vehicle CV whether or not there is a possibility of a contact accident or the degree of the contact accident with high accuracy.
　接触予測値が第二の閾値を超えた場合、すなわち、自動二輪車１００と対向車ＣＶが接触する可能性が高い場合には、対向車ＣＶの運転者に対して、短時間で直接的に接触事故の可能性を示す必要がある。この場合、本開示のハイビーム灯具ユニット３は、対向車ＣＶに向かって第二の方向に光を照射するように駆動することが好ましい。 When the predicted contact value exceeds the second threshold value, that is, when there is a high possibility that the motorcycle 100 and the oncoming vehicle CV come into contact with each other, the driver of the oncoming vehicle CV is directly contacted in a short time. It is necessary to show the possibility of an accident. In this case, it is preferable that the high beam lamp unit 3 of the present disclosure is driven so as to irradiate light in the second direction toward the oncoming vehicle CV.
　接触予測値が第一の閾値を超えた場合であって第二の閾値を超えない場合、すなわち、自動二輪車１００と対向車ＣＶが接触する可能性は高くはないものの対向車ＣＶに対して注意喚起が必要な場合、ハイビーム灯具ユニット３は路面に向かって第一の方向に光を照射するように駆動してもよい。すなわち接触予測値が高くない場合には、対向車ＣＶの運転者に対するグレアを避けつつ、運転者に対して路面に照射された光を通じて接触事故の可能性を示すことができる。 If the predicted contact value exceeds the first threshold value and does not exceed the second threshold value, that is, the possibility that the motorcycle 100 and the oncoming vehicle CV come into contact is not high, but be careful of the oncoming vehicle CV. When arousal is required, the high beam lamp unit 3 may be driven to irradiate light in the first direction toward the road surface. That is, when the contact prediction value is not high, the possibility of a contact accident can be shown to the driver through the light radiated to the road surface while avoiding glare to the driver of the oncoming vehicle CV.
　接触予測値が第一の閾値から第二の閾値を超えた場合、ハイビーム灯具ユニット３は、第一の方向から第二の方向へ、光の照射方向を変更する。車体から路面に向かって照射されていた光の照射方向が、車体から対向車ＣＶに向かう光の照射方向へ変更するため、対向車ＣＶの運転者は接触予測値が高いことを短時間で認知することができる。これにより、本開示は対向車ＣＶの運転者に対して安全運転を促し、接触事故を抑制することができる。 When the contact prediction value exceeds the first threshold value to the second threshold value, the high beam lamp unit 3 changes the light irradiation direction from the first direction to the second direction. Since the irradiation direction of the light emitted from the vehicle body toward the road surface changes to the irradiation direction of the light emitted from the vehicle body toward the oncoming vehicle CV, the driver of the oncoming vehicle CV recognizes that the contact prediction value is high in a short time. can do. Thereby, the present disclosure can encourage the driver of the oncoming vehicle CV to drive safely and suppress a contact accident.
　光の照射方向の変更として、後述するＡＤＢモードにおいてランプ制御部５が、照射領域と非照射領域を切り替えるよう、各個別光源３０を制御してもよい。 As a change in the light irradiation direction, each individual light source 30 may be controlled so that the lamp control unit 5 switches between an irradiation region and a non-irradiation region in the ADB mode described later.
　ランプ制御部５により実行されるＡＤＢモードについて説明する。ランプ制御部５は、例えば外部センサ７が取得する環境情報に基づいて、対向車ＣＶの存否および対向車ＣＶの存在位置（自動二輪車１００から対向車ＣＶまでの距離、灯具前方の所定位置、例えば灯具前方２５ｍの位置に配置された仮想鉛直スクリーン上における対向車ＣＶの角度座標など）を含む対向車ＣＶの状況を検出する。また、ランプ制御部５は、例えばバンク角センサ６が取得する車体の傾斜角情報に基づいて、車体の傾きを検出する。ランプ制御部５は、例えば速度センサ８が取得する速度情報に基づいて、自動二輪車１００の走行と停止とを含む、自動二輪車１００の状況を検出する。ランプ制御部５は、外部センサ７、バンク角センサ６、および速度センサ８が取得する情報に基づいて、配光パターン（ロービーム配光パターン、ハイビーム配光パターンおよび路面描画配光パターン）を制御する。 The ADB mode executed by the lamp control unit 5 will be described. The lamp control unit 5 determines the presence / absence of the oncoming vehicle CV and the existence position of the oncoming vehicle CV (distance from the motorcycle 100 to the oncoming vehicle CV, a predetermined position in front of the lamp, for example, based on the environmental information acquired by the external sensor 7. The status of the oncoming vehicle CV including the angular coordinates of the oncoming vehicle CV on the virtual vertical screen arranged at a position 25 m in front of the lamp is detected. Further, the lamp control unit 5 detects the inclination of the vehicle body based on, for example, the inclination angle information of the vehicle body acquired by the bank angle sensor 6. The lamp control unit 5 detects the situation of the motorcycle 100, including the running and stopping of the motorcycle 100, based on the speed information acquired by the speed sensor 8, for example. The lamp control unit 5 controls the light distribution pattern (low beam light distribution pattern, high beam light distribution pattern, road surface drawing light distribution pattern) based on the information acquired by the external sensor 7, the bank angle sensor 6, and the speed sensor 8. ..
　ランプ制御部５は、外部センサ７から環境情報を取得すると、当該検出結果に基づいてハイビーム灯具ユニット３の複数の個別光源３０の点消灯を個別に制御する。具体的にランプ制御部５は、複数の個別光源３０のうちハイビーム配光パターンＰＨの光照射に使用される部分パターンの個別光源３０を点灯状態とし、ハイビーム配光パターンＰＨの光照射に使用されない部分パターンの個別光源３０を消灯状態とするよう、ハイビーム灯具ユニット３の複数の個別光源３０をそれぞれ制御する。 When the lamp control unit 5 acquires environmental information from the external sensor 7, the lamp control unit 5 individually controls turning on and off of a plurality of individual light sources 30 of the high beam lamp unit 3 based on the detection result. Specifically, the lamp control unit 5 turns on the individual light source 30 of the partial pattern used for the light irradiation of the high beam light distribution pattern PH among the plurality of individual light sources 30, and is not used for the light irradiation of the high beam light distribution pattern PH. Each of the plurality of individual light sources 30 of the high beam lamp unit 3 is controlled so that the individual light sources 30 of the partial pattern are turned off.
　通常ハイビーム灯具ユニット３は、対向車ＣＶの運転者に対してグレアを与えないように、ハイビーム配光パターンＰＨを照射する。具体的には、ハイビーム配光パターンにおいて、対向車ＣＶの運転者に対応する部分パターンの個別光源３０を消灯し、その他の部分パターンの個別光源を点灯する。しかしながら接触予測値が第二の閾値を超えた場合、対向車ＣＶの運転者に対して、短時間で直接的に接触事故の可能性を示すため、対向車ＣＶの運転者に対応する部分パターンの個別光源３０を、消灯状態から点灯状態に変更することが好ましい。個別光源３０が消灯状態から点灯状態に変更することで、対向車ＣＶの運転者は接触事故の可能性を認知することができる。 Normally, the high beam lamp unit 3 irradiates the high beam light distribution pattern PH so as not to give glare to the driver of the oncoming vehicle CV. Specifically, in the high beam light distribution pattern, the individual light sources 30 of the partial patterns corresponding to the driver of the oncoming vehicle CV are turned off, and the individual light sources of the other partial patterns are turned on. However, when the contact prediction value exceeds the second threshold value, the possibility of a contact accident is directly shown to the driver of the oncoming vehicle CV in a short time, so that the partial pattern corresponding to the driver of the oncoming vehicle CV is shown. It is preferable to change the individual light source 30 of the above from the off state to the on state. By changing the individual light source 30 from the off state to the on state, the driver of the oncoming vehicle CV can recognize the possibility of a contact accident.
　光の照射態様の変更は、照射方法の変更を含んでもよい。 The change in the light irradiation mode may include a change in the irradiation method.
　例えば、接触予測値が第二の閾値を超えた場合、対向車ＣＶの運転者に向けて、ハイビーム灯具ユニット３を点滅、すなわちパッシングさせてもよい。ハイビーム灯具ユニット３がパッシングすると、ハイビーム灯具ユニット３の照射態様が短時間の間に激しく変化することになる。接触予測値が第二の閾値を超えた場合には、照射態様の激しい光を対向車ＣＶの運転者に向けて照射することで、運転者は短時間で接触事故の可能性を認知しやすくなり、安全運転が促される。ハイビーム灯具ユニット３のパッシングの周波数は限定されないが、２Ｈｚ以上６Ｈｚ未満が好ましい。周波数が６Ｈｚ以上の場合、点灯と消灯の切り替えが早すぎるため、運転者は点滅を識別しにくい。逆に周波数が２Ｈｚ未満の場合には、点灯と消灯の切り替えが遅すぎるため、運転者が接触事故の可能性を認知しにくい。したがって周波数は２Ｈｚ以上６Ｈｚ未満が好ましい。 For example, when the contact prediction value exceeds the second threshold value, the high beam lamp unit 3 may be blinked, that is, passed toward the driver of the oncoming vehicle CV. When the high beam lamp unit 3 passes, the irradiation mode of the high beam lamp unit 3 changes drastically in a short period of time. When the contact prediction value exceeds the second threshold value, the driver can easily recognize the possibility of a contact accident in a short time by irradiating the driver of the oncoming vehicle CV with intense light in the irradiation mode. Therefore, safe driving is promoted. The passing frequency of the high beam lamp unit 3 is not limited, but is preferably 2 Hz or more and less than 6 Hz. When the frequency is 6 Hz or higher, it is difficult for the driver to identify the blinking because the switching between turning on and off is too early. On the contrary, when the frequency is less than 2 Hz, it is difficult for the driver to recognize the possibility of a contact accident because the switching between turning on and off is too slow. Therefore, the frequency is preferably 2 Hz or more and less than 6 Hz.
　上記形態では、単一のハイビーム灯具ユニット３の照射態様を変更することを説明したが、これに限らず、複数のランプを備えても良い。たとえば、ヘッドランプ１は、第二の方向に向けて光を照射するハイビーム灯具ユニット３（第二のランプの一例）と、第一の方向に向けて光を照射する路面描画ランプ４（第一のランプの一例）を用いてもよい。ハイビーム灯具ユニット３は、ＡＤＢモードなどを利用することにより、車体前方であって路面よりも高い位置における、光の調整に適している。路面描画ランプ４は、ハイビーム灯具ユニット３では照射しにくい領域、たとえば路面に向かう方向や車体側方などに向けて光を照射する。複数のランプを用いることで、一つのランプでは照射できない領域へも照射可能となり、照射態様の変化の種類を増やすことができる。すなわち、接触予測値の高低を複数のランプによって使い分けることで、対向車ＣＶの運転者に対してより高い精度で接触事故の可能性の有無または程度を示すことができる。 In the above embodiment, it has been explained that the irradiation mode of a single high beam lamp unit 3 is changed, but the present invention is not limited to this, and a plurality of lamps may be provided. For example, the headlamp 1 includes a high beam lamp unit 3 (an example of a second lamp) that irradiates light in a second direction and a road surface drawing lamp 4 (first) that irradiates light in a first direction. An example of a lamp) may be used. The high beam lamp unit 3 is suitable for adjusting light at a position in front of the vehicle body and higher than the road surface by using the ADB mode or the like. The road surface drawing lamp 4 irradiates light toward an area that is difficult to irradiate with the high beam lamp unit 3, for example, a direction toward the road surface or a side surface of the vehicle body. By using a plurality of lamps, it is possible to irradiate an area that cannot be irradiated by one lamp, and it is possible to increase the types of changes in the irradiation mode. That is, by properly using the high and low contact predicted values by a plurality of lamps, it is possible to indicate to the driver of the oncoming vehicle CV whether or not there is a possibility of a contact accident or the degree of contact accident with higher accuracy.
　接触予測値が第一の閾値を超えた場合であって第二の閾値を超えない場合、路面描画ランプ４は、路面に向かって第一の方向に、光を照射するように駆動してもよい。接触予測値が高くない場合には、対向車ＣＶの運転者に対するグレアを避けつつ、運転者に対して路面に照射された光を通じて接触事故の可能性を認知させることができる。
（第二実施例） When the contact prediction value exceeds the first threshold value and does not exceed the second threshold value, the road surface drawing lamp 4 may be driven to irradiate light in the first direction toward the road surface. good. When the contact prediction value is not high, it is possible to make the driver aware of the possibility of a contact accident through the light radiated to the road surface while avoiding glare to the driver of the oncoming vehicle CV.
(Second Example)
　図７は、自動二輪車１００が交差点を直進する場合であって、自動二輪車１００の左側から対象物が直進する状況を示す概要図を示す。図５または図６では対向車ＣＶまたは側方から来る車両ＣＶ２を外部センサ７が検出することで、ランプ制御部５は接触予測値を算出した。一方図７のように、外部センサ７が対象物を検出できない場合、交差点での衝突事故が起こる可能性がある。そこで第二実施例においては、外部センサ７に代えて、自動二輪車１００は外部装置から対象物に関する情報を受信する受信部７１を備え、ランプ制御部５は受信部７１によって受信した情報に基づいて接触予測値を算出する。第一実施例と同じ構成については説明を省略する。 FIG. 7 shows a schematic diagram showing a situation in which the motorcycle 100 goes straight through an intersection and the object goes straight from the left side of the motorcycle 100. In FIG. 5 or FIG. 6, the lamp control unit 5 calculates the contact prediction value by detecting the oncoming vehicle CV or the vehicle CV2 coming from the side by the external sensor 7. On the other hand, as shown in FIG. 7, if the external sensor 7 cannot detect the object, a collision accident at an intersection may occur. Therefore, in the second embodiment, instead of the external sensor 7, the motorcycle 100 includes a receiving unit 71 that receives information about the object from the external device, and the lamp control unit 5 is based on the information received by the receiving unit 71. Calculate the contact prediction value. The description of the same configuration as that of the first embodiment will be omitted.
　図７において、対象物である直進車ＣＶ３は、外部装置として、直進車ＣＶ３に関する情報を発信する第二の発信部７３を備える。すなわち図７の破線に示すように、自動二輪車１００の受信部７１は、直進車ＣＶ３の第二の発信部７３から、直進車ＣＶ３の位置や速度などの情報を受信する。直進車ＣＶ３の情報は、外部センサ７で検出するよりも、直進車ＣＶ３から受信した方がより正確な場合がある。自動二輪車１００と直進車ＣＶ３との車車間通信により、より正確な接触予測値をランプ制御部５は算出することができる。 In FIG. 7, the straight-ahead vehicle CV3, which is an object, includes a second transmission unit 73 that transmits information about the straight-ahead vehicle CV3 as an external device. That is, as shown by the broken line in FIG. 7, the receiving unit 71 of the motorcycle 100 receives information such as the position and speed of the straight-ahead vehicle CV3 from the second transmitting unit 73 of the straight-ahead vehicle CV3. The information of the straight-ahead vehicle CV3 may be more accurate when it is received from the straight-ahead vehicle CV3 than when it is detected by the external sensor 7. The lamp control unit 5 can calculate a more accurate contact prediction value by vehicle-to-vehicle communication between the motorcycle 100 and the straight-ahead vehicle CV3.
　第二実施例によれば、外部センサ７で対象物を検出できない場合でも、ランプ制御部５は受信部７１によって受信した情報に基づいて接触予測値を算出することができるので、光の照射態様の変化を通じて対象物に対して接触事故に関する注意を喚起することができる。 According to the second embodiment, even if the external sensor 7 cannot detect the object, the lamp control unit 5 can calculate the contact prediction value based on the information received by the reception unit 71, and thus the light irradiation mode. It is possible to call attention to contact accidents to the object through the change of.
　自動二輪車１００は、車体に関する情報を外部装置へ発信する第一の発信部７２を備えてもよい。接触予測値が所定の閾値を超えたとランプ制御部５が判断した場合、第一の発信部７２は、算出された当該接触予測値を対象物である直進車ＣＶ３へ送信してもよい。この場合、直進車ＣＶ３の運転者に対して、ヘッドランプ１の光の照射態様の変更に加えて、通信による注意喚起も送ることができる。 The motorcycle 100 may include a first transmission unit 72 that transmits information about the vehicle body to an external device. When the lamp control unit 5 determines that the contact prediction value exceeds a predetermined threshold value, the first transmission unit 72 may transmit the calculated contact prediction value to the straight-ahead vehicle CV3 which is an object. In this case, in addition to changing the light irradiation mode of the headlamp 1, the driver of the straight-ahead vehicle CV3 can be alerted by communication.
　外部装置は、直進車ＣＶ３の第二の発信部７３に限られず、信号機や道路標識に設けられても良い。例えば図７のように、信号機ＴＬまたは道路標識ＲＳが第二の発信部７３を備える場合、車車間通信は必要ない。自動二輪車１００と直進車ＣＶ３とが互いに通信できない状況においても、図７の一点鎖線のように、交差点に固定されている信号機ＴＬまたは道路標識ＲＳが情報を中継することができる。直進車ＣＶ３は交差点で刻一刻とその位置や速度を変えるため、必ずしも安定的に直進車ＣＶ３の位置情報や速度情報などを自動二輪車１００へ送信できるとは限らない。これに対して、信号機ＴＬまたは道路標識ＲＳに第二の発信部７３が設けられる場合には、定期的に、安定的に位置情報や速度情報などを自動二輪車１００の受信部７１に発信できるため、ランプ制御部５は車車間通信を用いずに路車間通信を用いて接触予測値を算出することができる。 The external device is not limited to the second transmitting unit 73 of the straight-ahead vehicle CV3, and may be provided on a traffic light or a road sign. For example, as shown in FIG. 7, when the traffic light TL or the road sign RS includes the second transmitting unit 73, vehicle-to-vehicle communication is not required. Even in a situation where the motorcycle 100 and the straight-ahead vehicle CV3 cannot communicate with each other, the traffic light TL or the road sign RS fixed at the intersection can relay the information as shown by the alternate long and short dash line in FIG. Since the straight-ahead vehicle CV3 changes its position and speed every moment at an intersection, it is not always possible to stably transmit the position information and speed information of the straight-ahead vehicle CV3 to the motorcycle 100. On the other hand, when the second transmitting unit 73 is provided on the traffic light TL or the road sign RS, the position information, the speed information, and the like can be periodically and stably transmitted to the receiving unit 71 of the motorcycle 100. , The lamp control unit 5 can calculate the contact prediction value by using the road-to-vehicle communication without using the vehicle-to-vehicle communication.
　第二実施例においても、第一実施例における光の照射態様を変更することができる。すなわち、第一の閾値及び第二の閾値を用いて、ランプ制御部５は接触予測値の高低（レベル）を複数の段階に分けて判断することができる。照射方向の変更やパッシングについても第二実施例において実施できる。 Also in the second embodiment, the light irradiation mode in the first embodiment can be changed. That is, using the first threshold value and the second threshold value, the lamp control unit 5 can determine the level of the contact prediction value by dividing it into a plurality of stages. The change of irradiation direction and passing can also be carried out in the second embodiment.
　以上、本開示の実施形態について説明をしたが、本開示の技術的範囲が本実施形態の説明によって限定的に解釈されるべきではないのは言うまでもない。本実施形態は単なる一例であって、請求の範囲に記載された発明の範囲内において、様々な実施形態の変更が可能であることが当業者によって理解されるところである。本開示の技術的範囲は請求の範囲に記載された発明の範囲およびその均等の範囲に基づいて定められるべきである。 Although the embodiments of the present disclosure have been described above, it goes without saying that the technical scope of the present disclosure should not be construed in a limited manner by the description of the present embodiments. It will be appreciated by those skilled in the art that this embodiment is merely an example and that various embodiments can be modified within the scope of the invention described in the claims.
