Description

車両用センサ／ランプ一体ユニット及び車両用センサ／ランプ制御システムVehicle sensor / lamp integrated unit and vehicle sensor / lamp control system
　本発明は、車両に搭載される車両用センサ／ランプ一体ユニット及び車両用センサ／ランプ制御システムに関する。 The present invention relates to a vehicle sensor / lamp integrated unit and a vehicle sensor / lamp control system mounted on a vehicle.
　従来、車両ドア側面に配置されたサイドミラーにウェルカムランプなどの路面描画用の光源ユニットやカメラなどのセンサを内蔵させた車両が知られている（例えば、特許文献１）。また、車両周囲の状況を検出するため、ミリ波レーダや赤外線センサ（例えばＬｉＤＡＲ）などのセンサ類を車両の前端部や車体側面等の外端部に配置することが提案されている。 Conventionally, there is known a vehicle in which a light source unit for drawing a road surface such as a welcome lamp and a sensor such as a camera are built in a side mirror arranged on the side of a vehicle door (for example, Patent Document 1). Further, in order to detect the situation around the vehicle, it has been proposed to arrange sensors such as a millimeter wave radar and an infrared sensor (for example, LiDAR) at the front end portion of the vehicle and the outer end portion such as the side surface of the vehicle body.

　しかしながら、上記のセンサ類やランプ，表示装置などをサイドミラーの筐体内に格納するとなると、搭載スペース上の制約が生じる。更に、今後、サイドミラーは電子化により小型化することが予想されるため、その制約がより一層に進行するおそれがある。一方、上記のセンサ類やランプ，表示装置が互いに離れた箇所に設置されると、過大な設置スペースを用意することが必要となり、見栄えが悪く、搭載性が悪化してしまう。 However, if the above sensors, lamps, display devices, etc. are stored in the side mirror housing, there will be restrictions on the mounting space. Furthermore, since it is expected that the side mirrors will be miniaturized due to digitization in the future, there is a possibility that the restrictions will be further advanced. On the other hand, if the above-mentioned sensors, lamps, and display devices are installed at locations separated from each other, it is necessary to prepare an excessive installation space, which makes the appearance unattractive and deteriorates the mountability.
　本発明は、このような点に鑑みてなされたものであり、搭載スペース上の制約を受けることなくセンサ及びランプの省設置スペース化を実現することが可能な車両用センサ／ランプ一体ユニット及び車両用センサ／ランプ制御システムを提供することを目的とする。 The present invention has been made in view of these points, and is a sensor / lamp integrated unit for vehicles and a vehicle capable of realizing a space-saving installation of sensors and lamps without being restricted by mounting space. It is an object of the present invention to provide a sensor / lamp control system for a vehicle.

A vehicle sensor / lamp integrated unit including a lamp that emits light, a surface plate portion that covers the sensor and is capable of transmitting the electromagnetic wave, and a holding portion that holds the sensor and the lamp.

The manufacturing effort can be saved and the simplification can be achieved. Further, since the sensor 10 and the lamp 20 are integrally installed at a location close to each other, the installation space can be reduced and the appearance can be maintained well, thereby saving without being restricted by the mounting space. It is possible to realize an installation space.
　更には、カメラ３０もセンサ１０及びランプ２０と一体ユニット１で一体化された状態で一括して車両２に組み込まれるので、カメラ３０を個別に車両２に組み込む構成とは異なり、製造上の手間を更に省いてその簡素化を図ることができる。また、センサ１０、ランプ２０、及びカメラ３０が互いに近い箇所に一体となって設置されるので、設置スペースを小さくして見栄えを良好に維持することができ、これにより、搭載スペース上の制約を受けることなく省設置スペース化を実現することができる。 Further, since the camera 30 is also integrated into the vehicle 2 in a state of being integrated with the sensor 10 and the lamp 20 by the integrated unit 1, unlike the configuration in which the camera 30 is individually incorporated into the vehicle 2, it takes time and effort in manufacturing. Can be further omitted to simplify it. Further, since the sensor 10, the lamp 20, and the camera 30 are integrally installed at a location close to each other, the installation space can be reduced and the appearance can be maintained well, thereby limiting the mounting space. It is possible to save installation space without receiving it.
　また、一体ユニット１は、車両２における車両斜め後方に向く傾斜面３ａを有するフェンダ部３に設置される。この一体ユニット１の設置によれば、センサ１０、ランプ２０、及びカメラ３０を傾斜面３ａを用いて適切に配置することで、センサ１０の電磁波照射方向、ランプ２０の光照射方向、及びカメラ３０カメラ指向方向などを車両後方Ｙに向け易くすることができる。このため、センサ１０、ランプ２０、及びカメラ３０の機能がその配置に起因して損なわれるのを防止することができる。 Further, the integrated unit 1 is installed on the fender portion 3 having the inclined surface 3a facing diagonally rearward of the vehicle in the vehicle 2.

It is possible to reduce the design restrictions (near the boundary with the glass). Therefore, according to the integrated unit 1 of the present embodiment, the functions of the sensor 10, the lamp 20, and the camera 30 can be ensured while improving the design of the vehicle.
　また、上記の如く一体ユニット１がフェンダ部３に設置されれば、周知の車両ドアと窓ガラスとの境界付近に設置される一般的なサイドミラーの筐体内にセンサ１０、ランプ２０、及びカメラ３０を格納する構造と異なり、搭載スペース上の制約が生じるのを回避することができ、搭載スペースの自由度を上げることができる。 Further, if the integrated unit 1 is installed in the fender portion 3 as described above, the sensor 10, the lamp 20, and the camera are housed in a general side mirror housing installed near the boundary between the well-known vehicle door and the window glass. Unlike the structure for storing the 30, it is possible to avoid restrictions on the mounting space and increase the degree of freedom in the mounting space.
　従って、一体ユニット１によれば、搭載スペース上の制約を受けることなくセンサ１０、ランプ２０、及びカメラ３０の省設置スペース化を実現することができる。 Therefore, according to the integrated unit 1, it is possible to save the installation space of the sensor 10, the lamp 20, and the camera 30 without being restricted by the mounting space.
　また、上記した一体ユニット１の設置によれば、車両ドアと窓ガラスとの境界付近で車幅方向外側に出っ張る部材を無くすことができるので、車両２の空力特性を改善することができ、これにより、車両２の燃費低減を図ることができ、風切り音の低減を図ることができる。また、一体ユニット１が、車両乗員の耳元に近い車両ドアと窓ガラスとの境界付近から物理的に遠いフェンダ部３に設置されるので、車両２の騒音低減を図ることができる。 Further, by installing the integrated unit 1 described above, it is possible to eliminate the member protruding outward in the vehicle width direction near the boundary between the vehicle door and the window glass, so that the aerodynamic characteristics of the vehicle 2 can be improved. As a result, the fuel consumption of the vehicle 2 can be reduced, and the wind noise can be reduced. Further, since the integrated unit 1 is installed in the fender portion 3 physically far from the vicinity of the boundary between the vehicle door and the window glass near the ear of the vehicle occupant, the noise of the vehicle 2 can be reduced.
　更に、フェンダ部３にセンサ１０、ランプ２０、及びカメラ３０が配置されれば、車両ドアと窓ガラスとの境界付近にセンサ１０、ランプ２０、及びカメラ３０が配置される構成と比較して、センサ１０、ランプ２０、及びカメラ３０をその機能を確保した状態で配置できる領域を広範囲なものとすることができるので、そのセンサ１０、ランプ２０、及びカメラ３０の配置自由度を高めることができる。 Further, if the sensor 10, the lamp 20, and the camera 30 are arranged on the fender portion 3, the sensor 10, the lamp 20, and the camera 30 are arranged near the boundary between the vehicle door and the window glass. Since the area in which the sensor 10, the lamp 20, and the camera 30 can be arranged while ensuring their functions can be widened, the degree of freedom in arranging the sensor 10, the lamp 20, and the camera 30 can be increased. ..
　そして、センサ１０、ランプ２０、及びカメラ３０は、上記の如く、フェンダ部３の最外の車幅方向位置よりも車幅方向外側に出っ張らないようにすなわち車幅方向内側に収まるように配置されている。この構造では、センサ１０、ランプ２０、及びカメラ３０がフェンダ部３の最外の車幅方向位置よりも車幅方向外側に出っ張らないので、車両２の空力特性が損なわれるのを回避することができる。 Then, as described above, the sensor 10, the lamp 20, and the camera 30 are arranged so as not to protrude outward in the vehicle width direction from the outermost position in the vehicle width direction of the fender portion 3, that is, to fit inside in the vehicle width direction. ing. In this structure, since the sensor 10, the lamp 20, and the camera 30 do not protrude outward in the vehicle width direction from the outermost position in the vehicle width direction of the fender portion 3, it is possible to avoid impairing the aerodynamic characteristics of the vehicle 2. can.

The control unit 70 may be held by the jig 60 of the integrated unit 1 and connected to the sensor 10, the lamp 20, and the camera 30 as a part of the integrated unit 1, or may be separated from the jig 60. It may be attached to the vehicle body side and connected to the sensor 10, the lamp 20, and the camera 30 via a harness.
　制御部７０には、センサ１０（具体的には、ミリ波レーダ１１及びＬｉＤＡＲ１２）及びカメラ３０（具体的には、電子サイドミラーカメラ３１及びサイドビューカメラ３２）が出力する車両周囲の状況に応じた検出信号が入力される。制御部７０は、センサ１０及びカメラ３０からの検出信号に基づいて、ランプ２０（具体的には、ターンランプ２１及び路面描画用ランプ２２）の発光を制御することが可能である。 The control unit 70 responds to the situation around the vehicle output by the sensor 10 (specifically, the millimeter-wave radar 11 and the LiDAR 12) and the camera 30 (specifically, the electronic side mirror camera 31 and the side view camera 32). The detection signal is input. The control unit 70 can control the light emission of the lamp 20 (specifically, the turn lamp 21 and the road surface drawing lamp 22) based on the detection signals from the sensor 10 and the camera 30.
　具体的には、制御部７０は、センサ１０の検知範囲やカメラ３０の撮像範囲に対象物が進入したか否かを判別する（図５に示すステップＳ１００）。例えば、この判別は、ミリ波レーダ１１の電磁波照射範囲に対象物が進入したか否か、電子サイドミラーカメラ３１の撮像範囲に映し出された対象物が自車両に近づくか否かなどに基づいて行われる。 Specifically, the control unit 70 determines whether or not an object has entered the detection range of the sensor 10 or the image pickup range of the camera 30 (step S100 shown in FIG. 5). For example, this determination is based on whether or not an object has entered the electromagnetic wave irradiation range of the millimeter-wave radar 11, and whether or not the object projected in the imaging range of the electronic side mirror camera 31 approaches the own vehicle. Will be done.
　制御部７０は、センサ１０の検知範囲やカメラ３０の撮像範囲に対象物が進入したと判別した場合は、次に、例えば両者の相対速度が大きく或いは対象物の予想軌跡が自車両に向かっていることで所定時間内に自車両とその対象物との間で接触が生じる危険が予測されるか否かを判別する（ステップＳ１１０）。尚、この判別は、センサ１０やカメラ３０による検出結果の時間変化に基づいて行われるものであってよいし、更には、そのセンサ１０やカメラ３０による検出結果と車両挙動（例えばドア開など）とに基づいて行われるものであってよい。 When the control unit 70 determines that the object has entered the detection range of the sensor 10 or the image pickup range of the camera 30, then, for example, the relative speed between the two is large or the predicted trajectory of the object is toward the own vehicle. It is determined whether or not a risk of contact between the own vehicle and the object thereof is predicted within a predetermined time (step S110). It should be noted that this determination may be performed based on the time change of the detection result by the sensor 10 or the camera 30, and further, the detection result by the sensor 10 or the camera 30 and the vehicle behavior (for example, door opening). It may be performed based on.
　そして、制御部７０は、自車両と対象物との間でその危険が予測されると判別した場合は、その危険をその対象物を含む車両周囲に知らせ或いは相手に危険回避行動を促すために車両周囲に向けた或いはその対象物に向けた発光をランプ２０に対して指令する（ステップＳ１２０）。かかる指令が行われると、ランプ２０が発光する。例えば、ターンランプ２１が高速で点滅し、或いは、路面描画用ランプ２２が路面に向けて危険を知らせ或いは相手に危険回避行動を促すための描画を行う。 Then, when the control unit 70 determines that the danger is predicted between the own vehicle and the object, the control unit 70 informs the surroundings of the vehicle including the object of the danger or urges the other party to take a danger avoidance action. The lamp 20 is instructed to emit light toward the surroundings of the vehicle or toward the object thereof (step S120). When such a command is given, the lamp 20 emits light. For example, the turn lamp 21 blinks at high speed, or the road surface drawing lamp 22 draws toward the road surface to notify the danger or encourage the other party to take a danger avoidance action.
　この構成においては、車両周囲の状況を検出するセンサ１０と、車両周囲の状況を撮像するカメラ３０と、それらのセンサ１０やカメラ３０による検出結果に基づいて発光されるランプ２０と、が一つの一体ユニット１で一体化されて互いに連動して機能する。具体的には、センサ１０やカメラ３０により検出される車両周囲の状況から車両の危険性が判断され、危険が生じる可能性があるときに必要なメッセージが提示されるようにランプ２０が発光される。 In this configuration, a sensor 10 that detects the situation around the vehicle, a camera 30 that captures the situation around the vehicle, and a lamp 20 that emits light based on the detection results of the sensors 10 and the camera 30 are one. It is integrated by the integrated unit 1 and functions in conjunction with each other. Specifically, the lamp 20 emits light so that the danger of the vehicle is determined from the situation around the vehicle detected by the sensor 10 and the camera 30, and a necessary message is presented when the danger may occur. To.
