Description
本創作涉及一種共用車輛燈具之光源模組和反射鏡的「具有毫米波雷達的車用燈具系統」。This creation involves a "vehicle lamp system with millimeter wave radar" that shares the light source module and reflector of the vehicle lamp.
隨著車聯網和自動駕駛科技的興起,越來越多車輛開始導入車載雷達設備,所述的車載雷達可以探測車輛外部物體位置、距離和速度,更高階者可以辨識物體類型或者根據雷達訊號進行成像,使駕駛人獲得更多行車訊息可供參考,目前車載雷達技術包含有紅外線雷達、超音波雷達、光達(LiDAR)、攝影機和毫米波雷達(mmwave radar),然而,毫米波雷達不受天氣環境影響、探測距離較遠,因此而成為車載雷達較佳選擇。With the rise of the Internet of Vehicles and autonomous driving technology, more and more vehicles have begun to introduce on-board radar equipment. The on-board radar can detect the position, distance and speed of external objects in the vehicle. Higher-level people can identify the type of objects or perform based on radar signals. Imaging allows drivers to obtain more driving information for reference. The current vehicle radar technology includes infrared radar, ultrasonic radar, LiDAR, camera and millimeter wave radar. However, millimeter wave radar is not The weather environment affects and the detection distance is relatively long, so it is a better choice for vehicle radar.
現有的車載雷達常用於輔助車輛測距之應用,其中,車載雷達常裝設於保險桿之位置,這種方式需要在保險桿另外開設安裝孔,這對於保險桿結構有較大的安全性疑慮,且如此一來,車載雷達由於空間上的限制,一般只能採用PCB微帶天線(microstrip antenna)直接發出與接收無線電波,而無法使用具備高指向性的拋物面天線提高增益,因此雷達的角度與解析度不易提高,同時天線孔徑的不足限制了雷達可以偵測的最遠距離,雖有發明人將毫米波雷達設置於車燈,請參照美國發明專利第US8803728B2號「Millimeter wave radar-equipped headlamp」,其係揭露一種配備有毫米波雷達的前照燈,其主要由一照明裝置單元、一架體及一毫米波雷達所組成,且照明裝置單元可包含一投射透鏡、一光源、一反射器和一遮光罩,所述的投射透鏡用以將光源產生的光線透射出車燈外部,所述的光源用以產生照明光源,所述的反射器用以反射光源所產生的光線,將光線反射至車燈外部,所述的遮光罩用以阻擋來自反射器的部分反射光,又,毫米波雷達可包含一天線模組、一毫米波導波管、一毫米波反射鏡和一控制模組,其中:所述的天線模組用以接收毫米波,所述的毫米波導波管用以發射毫米波,所述的毫米波反射鏡可將毫米波導波管產生的毫米波反射至投射透鏡外部,所述的控制模組用以控制天線模組;據此,此美國專利提出一種將毫米波雷達設置於車輛前照燈內的發明;另有其他參考文獻,如下: (1) 中國發明專利第CN107887686B號「車載陣列雷達天線和車燈」; (2) 中國發明專利第CN109375191A號「共照射源3D雷射雷達和2D探測器超空間解析度資訊獲取方法及裝置」; (3) 中國發明專利第CN110103810A號「三維探測照明系統及汽車」; (4) 美國發明專利第US10421390B2號「LAMP DEVICE」; (5) 美國發明專利第US8803728B2號「Millimeter wave radar-equipped headlamp」; (6) 美國發明專利第US2019275923A1號「SENSOR SYSTEM」 (7) 美國發明專利第US20180275269A1 號「RADAR ARRANGEMENT」。 Existing vehicle-mounted radars are often used to assist vehicle ranging applications. Among them, vehicle-mounted radars are often installed in the position of the bumper. This method requires additional installation holes in the bumper, which has greater safety concerns for the bumper structure And as a result, due to space constraints, vehicle-mounted radars generally can only use PCB microstrip antennas to directly emit and receive radio waves, instead of using parabolic antennas with high directivity to increase the gain, so the radar angle And the resolution is not easy to improve, and the lack of antenna aperture limits the maximum distance that the radar can detect. Although some inventors have installed millimeter wave radar in the car lights, please refer to the US Patent No. US8803728B2 "Millimeter wave radar-equipped headlamp" "It discloses a headlamp equipped with a millimeter-wave radar, which is mainly composed of a lighting device unit, a frame and a millimeter-wave radar, and the lighting device unit may include a projection lens, a light source, and a reflector. The projection lens is used to transmit the light generated by the light source out of the car lamp, the light source is used to generate an illumination light source, and the reflector is used to reflect the light generated by the light source and reflect the light To the outside of the car light, the light shield is used to block part of the reflected light from the reflector. In addition, the millimeter wave radar may include an antenna module, a millimeter waveguide tube, a millimeter wave reflector, and a control module. Wherein: the antenna module is used to receive millimeter waves, the millimeter waveguide tube is used to transmit millimeter waves, and the millimeter wave mirror can reflect the millimeter waves generated by the millimeter waveguide tube to the outside of the projection lens. The control module described is used to control the antenna module; accordingly, this US patent proposes an invention in which a millimeter wave radar is installed in the headlight of a vehicle; there are other references as follows: (1) China Invention Patent No. CN107887686B "Vehicle Array Radar Antenna and Car Light"; (2) Chinese Invention Patent No. CN109375191A "Method and device for acquiring hyperspace resolution information of common illumination source 3D laser radar and 2D detector"; (3) Chinese Invention Patent No. CN110103810A "Three-dimensional Detection Illumination System and Automobile"; (4) US Invention Patent No. US10421390B2 "LAMP DEVICE"; (5) US Invention Patent No. US8803728B2 "Millimeter wave radar-equipped headlamp"; (6) U.S. Invention Patent No. US2019275923A1 "SENSOR SYSTEM" (7) US Invention Patent No. US20180275269A1 "RADAR ARRANGEMENT".
然而,第US8803728B2號美國專利所提出的配備有毫米波雷達的前照燈,其毫米波雷達探測範圍極為窄小,若要增加毫米波雷達之探測範圍,則必須增加毫米波雷達之設置數量,若增加毫米波雷達數量,所增設的毫米波雷達面積勢必增加,這將遮擋到光源的照射路徑,提升毫米波雷達的探測範圍,卻也犧牲掉照明光線的照射範圍,對於車輛而言更加危險,據此,如何將毫米波雷達結合在車燈內部,並且不會干涉到照明光源,同時能保證雷達具備較高的遠場指向性增益與角解析度,此乃待需解決之問題。However, the headlamp equipped with millimeter-wave radar proposed in US Patent No. US8803728B2 has a very narrow detection range of millimeter-wave radar. To increase the detection range of millimeter-wave radar, the number of millimeter-wave radars must be increased. If the number of millimeter-wave radars is increased, the area of the millimeter-wave radars added will inevitably increase, which will block the illumination path of the light source, increase the detection range of the millimeter-wave radar, but also sacrifice the illumination range of the illumination light, which is more dangerous for vehicles According to this, how to integrate the millimeter wave radar inside the car lights without interfering with the illuminating light source while ensuring that the radar has high far-field directivity gain and angular resolution is a problem to be solved.
另,車載毫米波雷達一般採用相位控制陣列形式的收發方式,以多組天線形成基線,控制發射端的波束方向,但這樣的系統中,其單一天線的指向性增益通常較低,無法形成具備完整指向性的波束,因此可能存在車輛間不同發射源互相干擾的問題,而接收端則因為合成波束的指向性限制,即便以較複雜的演算法,亦只能在一定程度內減少干擾,故在有限的信噪比下,視角內探測多個目標的信號之間容易產生混淆,同時在有限的發射功率下,可探測的距離範圍因為波束分散而被限制。In addition, vehicle-mounted millimeter-wave radars generally use phase control arrays to form a base line to control the beam direction of the transmitting end. However, in such a system, the directivity gain of a single antenna is usually low, and it is impossible to form a complete antenna. Because of the directional beam, there may be a problem of mutual interference between different emission sources between vehicles, and the receiving end due to the directional limitation of the composite beam, even with a more complex algorithm, can only reduce the interference to a certain extent. With a limited signal-to-noise ratio, it is easy to cause confusion between the signals of multiple targets detected within the viewing angle. At the same time, with a limited transmit power, the detectable distance range is limited due to beam dispersion.
有鑑於上述的問題,本創作人係依據多年來從事相關行業的經驗,針對毫米波雷達和車輛照明燈具進行研究及改進;緣此,本創作之主要目的在於提供一種將毫米波雷達設置於車輛照明燈具,並且共用車輛照明燈具的光源模組和反射鏡的具有毫米波雷達的車用燈具系統。In view of the above-mentioned problems, the author is based on years of experience in related industries to research and improve millimeter wave radars and vehicle lighting fixtures; for this reason, the main purpose of this creation is to provide a way to install millimeter wave radars on vehicles.
