本发明一实施例中,提供一种辅助驾驶***,包括光探测与测量模组、LiFi驱动模块和照明模组。光探测与测量模组用于探测光探测与测量模组周围的物体的位置参数。LiFi驱动模块与光探测与测量模组连接,LiFi驱动模块可接收位置参数并将位置参数调制生成LiFi信号。照明模组与LiFi驱动模块连接,用于提供照明及同时发射LiFi信号。
工作原理:光探测与测量模组可探测得出周围的物体的位置参数(如物体与光探测与测量模组之间的距离L0、物体相对于光探测与测量模组的方位等),LiFi驱动模块接收位置参数后,将位置参数信息调制生成LiFi信号,该LiFi信号可直接与照明光源的照明光同时向外发射。具体的,参考图1,当上述辅助驾驶***设置于本车10上,光探测与测量模组向前发射的载有位置参数信息的LiFi信号可被前方行驶中的其他车辆20接收。当前方的其他车辆20接收到LiFi信号后,可根据信号内容进行后续决策,如位置参数信息显示两车之间距离L0过近时可变道或加速拉大两车之间的距离,还可闪烁尾灯以警示后车;当处于前方的其他车辆20上安装有显示模块21时,还可以将距离L0在显示模块21上显示出来以供本车10查看,方便本车10驾驶员及时、准确得知与前车之间的距离信息。
除了位置参数信息的传输,LiFi信号还可以传输其他信息,如路况、天 气、路径规划、突发状况等信息,从而使车辆成为车辆网内的一个移动的信息共享基站。
本实施例中,光探测与测量模组可主动探测周围的物体(比如其他车辆20)的位置参数,位置参数经LiFi驱动模块调制后直接通过照明模组发射出,为位置参数提供了一条传输途径,其他车辆20了解情况后可以及时采取后续措施(如闪烁尾灯或显示距离以警示本车10)从而降低碰撞事故发生的概率;另外,其他数据信息也可以发送到照明模组所能够照射到的车辆,如危险求救信息、娱乐信息共享、路况信息等等,从而有利于实现两车之间私密信息的共享传输。采用LiFi的方式传递V2V或V2X信息,较之其他手段拥有更好的私密性,不易被窃取隐私信息。
本实施例使照明模组进一步整合了探测和传输数据的功能,增加了整体的功能性和价值,更有利于迎合消费者需求和市场推广。

本实施例中,本车10的LiFi驱动模块可调制信息生成LiFi信号并通过 本车10的照明光源发射LiFi信号,LiFi信号可被其他车辆20安装的LiFi接收模块520接收,LiFi接收模块520将信号中的位置参数(两车之间的距离L0、方向、相对车速等)通过设于前方车辆的车尾部的显示模块21(如显示屏、后挡风玻璃投影显示***、带有显示功能的车辆尾灯、车尾地面投影显示***等)可直接显示出来,方便本车10驾驶员准确得知与前车之间的距离信息。本实施例中,为本车10驾驶员得知与其他车辆20之间的距离信息提供了很好的途径,尤其是在本车10附近的车辆较多时,本车10驾驶员可实时了解与各个车辆之间的距离信息,当发生潜在追尾情况时,可以视情况及时采取必要的措施如减速变道或调节驾驶方向等以避免事故发生,进一步降低了事故发生的概率。
本车10照明光源所发射的LiFi信号还可以传输其他信息给其他车辆20,如路况、天气、路径规划、突发状况等信息,信息可通过前方车辆尾部的显示模块21显示出来方便本车驾驶员实时查看。
在一些实施例中,光探测与测量模组及照明模组设于本车10的车头部,LiFi接收模块520及显示模块21设于其他车辆20的车尾部。
本实施例中,光探测与测量模组及照明模组设于本车10的车头部,有利于扩大光探测与测量模组的探测角度和范围,以利于缩小探测盲区;LiFi接收模块520及显示模块21设于其他车辆20的车尾部,有利于接收LiFi信号,同时方便本车10查看显示模块21上显示的信息。
在一些实施例中,光探测与测量模组包括相连接的探测光源和探测组件,探测光源用于生成探测用光,探测组件可将探测用光向外发射从而探测得出物体的位置参数;
照明模组包括相连接的照明光源和照明组件,照明光源用于生成照明用 光,照明组件用于接收并向外发射照明用光。
本实施例中,探测组件通过发射探测用光探测得出物体的位置参数,具体的,探测组件向外发射的探测用光(如红外激光)遇到物体时可被物体表面反射,反射光传回被探测组件接收后,车辆控制台基于接收到的反射光的入射角度可判断出物体相对于本车10的方向,同时可根据接收反射光与发射探测信号的时间间隔计算得出物体与本车10之间的距离L0。以上描述的是利用光反射原理探测得到周围物体方位的方法,当然,在其他一些实施例中,还可通过检测探测用光反馈的其他参数探测得知周围物体的方位,皆在本发明的保护范围。
在一些实施例中,LiFi驱动模块集成于照明光源的驱动器中。该设置有利于节约安装空间和整体的小型化设计。当然,在其他一些实施例中,LiFi驱动模块可设于照明光源外部,且与照明光源相连接,此处不作限制。
实际安装时,探测组件可安装于车辆前部例如散热格栅或保险杠位置,也可以直接安装于车灯内部,但是均有一定的问题:安装在保险杠位置时,在发动机舱附近会额外增加较多线束,并且需要额外配置清洗***;直接安装在灯具内部时,会造成灯具体积的庞大,并且探测组件发热会为车灯带来额外的散热负担。因此,在一些实施例中,照明光源和探测光源组合形成光源总成100,光源总成100通过光传输部件200分别与照明组件、探测组件相连接。
光源总成100独立于照明组件及探测组件,并通过光传输部件200与照明组件及探测组件连接,可将产生的照明用光及探测用光通过光传输部件200直接传输至照明组件及探测组件,分别用于提供照明和探测位置。
本实施例中,光源总成100独立安装有如下优点:
(1)将光源总成100独立于照明组件和探测组件,可将占据体积以及发热量巨大的光源总成100与其他功能组件分开,将光源总成100灵活布置于散热通风条件较好的地方即可快速散热,例如车辆的发动机舱内部、驾驶舱内等位置,从而有利于延长设备整体的使用寿命。并且,由于光源总成100独立设置,在安装时可以将光源总成100设于人员容易触及的位置,不仅安装方便,同时也利于维修与更换,为后续的维护提供便利;
(2)由于体积较大的光源总成100被独立安装,而探测组件的体积较小、可以邻近照明组件布置,从而有利于模组整体的小型化设计,即使将探测组件与照明组件集成一体后不会占用多余的空间;
(3)由于体积较大的光源总成100被独立设置且散热问题得到了解决,因此探测组件可与照明组件集成布置于车灯安装位,有利于扩大探测角度和范围和缩小探测盲区;照明组件、探测组件与光源总成100的连接方式简单,不需要布置大量的连接线束,结构简洁、节约了安装空间,方便了后期维护和检修。
(4)探测组件与照明组件结合后可固定于车灯内部被保护起来,不影响车辆的整体外观,设在车灯内部也不容易沾染灰尘。
在一些实施例中,光源总成100上可以设置散热装置110,例如风冷散热器或水冷散热器,从而采用风冷或水冷的方式为光源总成100散热。
参考图3和图4,在一些实施例中,照明组件包括安装壳体310、荧光部件、聚光单元330和透镜单元340。安装壳体310形成前后贯通的空腔。荧光部件设于安装壳体310后端,且荧光部件位于光传输部件200输出的照明用光的光路上,用于在照明用光的激发下发射出可见光。聚光单元330设于荧光部件一侧,用于汇聚可见光形成照明光束并使照明光束在空腔内传输。 透镜单元340设于安装壳体310前端,用于调节照明光束从而使其以一定角度向外发射。
聚光单元330具体可以选择反射镜。本实施例中以照明用光作为激发光,例如照明用光可选用高能量的蓝色激光,具体的,经光传输部件200传输至照明组件的照明用光(如蓝色激光)可通过设于安装壳体310后端的激光头发出,荧光部件在照明用光的激发下可发生能级跃迁并发出可见的荧光,可见光经聚光单元330汇聚形成可见光束后从透镜单元340穿过向外发射提供照明。
本实施例中,聚光单元330和透镜单元340汇聚荧光形成可见光束并对可见光束进行调节,安装壳体310为可见光束提供了传输的空间;荧光部件发出的可见荧光照明亮度高,在需要同等照明强度的情况下,能耗比传统的照明方式少,节省了成本;且由于不同颜色的荧光部件被激发后会发射不同颜色的光,因此可根据实际发光颜色需求设置不同颜色的荧光部件,从而可以被激发出所需颜色的光,省去了对光源预先进行调制处理或更换不同种类的光源总成100的麻烦,对不同发光需求的适应性更强,也使整个照明组件的结构简单化,使用更方便。
参考图4和图5,在一些实施例中,荧光部件包括散热器321a和荧光片322a。散热器321a固定于安装壳体310后端。荧光片322a固定于散热器321a且位于照明用光的光路上,荧光片322a可接收并反射照明用光,荧光片322a的表面朝向聚光单元330。
具体的,光传输部件200所传输的照明用光401a(如蓝色激光)可通过设于安装壳体310后端的激光头400a发出,激光头400a内部包含有光学组件,用于将照明用光光型做初步整形;荧光片322a被照射到其表面的照明用 光401a激发出可见的荧光,荧光直接被聚光单元330汇聚形成可见光束,照射到荧光片322a表面的照明用光401a可同时被荧光片322a反射;散热器321a为荧光片322a提供了安装空间,同时可将荧光发射时产生的热量及时发散出去,避免热量过高损坏整个设备。在一个或多个实施例中,,荧光片322a通过散热胶323a贴附于散热器321a表面,可进一步提升散热效果;且荧光片322a贴附于散热器321a后可在荧光片322a周围设置固定钣金326a以防止荧光片322a脱落。
在一些实施例中,荧光片322a的表面与光传输部件200输出的照明用光401a的夹角为锐角,可方便将照明用光401a直接向外反射出去。
采用本实施例的设置形式可直接反射照明用光401a,荧光片322a的表面朝向聚光单元330,有利于汇聚荧光;荧光片322a直接与散热器321a贴合,方便热量及时发散出去,以保证荧光转换效率。
进一步的,还包括光检测板325a,设于被荧光片322a反射的照明用光401a的光路上,用于检测被荧光片322a反射的照明用光401a的能量。这是因为作为激发光的照明用光401a(比如蓝色激光)通常具有较高的能量,当被反射的照明用光401a能量较高时会对人眼造成损伤,特别是当荧光片322a失效后照明用光401a会被荧光片322a全部反射出去,一旦射入人眼会直接导致失明,而利用光检测板325a可检测被荧光片322a反射的照明用光401a的能量,当检测到的光的能量较大时可关闭光源总成100或降低发光功率以保护人眼安全,具体使用时,可将光检测板325a直接与车辆控制部件相连接,光检测板325a检测到的能量值可直接反馈至车辆控制部件,车辆控制部件判断检测到的能量值超过内部设置的能量阈值时自动关闭光源总成100或调低发光功率。
进一步的,荧光片322a表面覆盖蓝宝石片324a,蓝宝石片324a可以增加光线透过率,一方面有利于作为激发光的照明用光401a透过并与荧光片322a接触,另一方面有利于荧光片322a产生的荧光透过并射向聚光单元330。
参考图6,在一些实施例中,荧光部件包括荧光片322b,位于照明用光的光路上;荧光片322b可接收照明用光并使照明用光透过。
具体的,光传输部件200所传输的照明用光401b(如蓝色激光)可通过激光头400b发出,荧光片322b被射到其表面的照明用光401b激发后发射出荧光,且照明用光401b可直接穿过荧光片322b,从而采用本实施例的设置方式可直接透射照明用光401b,设置结构简单。在一个或多个实施例中,荧光片322b的表面与光传输部件200输出的照明用光401b成直角,荧光片322b的表面与光传输部件200输出的照明用光401b成直角,有利于尽可能多的接收作为激发光的照明用光401b,多余的照明用光401b可直接穿过荧光片322b向外发射。
荧光片322b两侧设有蓝宝石层324b,蓝宝石层324b用于散热且可增加荧光的透过率。具体的,蓝宝石层324b直接与荧光片322b贴合,可将荧光片322b发射荧光时产生的热量及时发散出去,避免热量过高损坏整个设备;同时,蓝宝石层324b可以增加光线透过率,一方面有利于作为激发光的照明用光401b透过并与荧光片322b接触,另一方面有利于荧光片322b产生的荧光透过并射向聚光单元330。
可以理解的是,在其他的一些实施例中,照明组件可以是设于光传输部件200输出的照明用光的光路上的反射聚光透镜,此时照明用光直接选用可见光,可见光从反射聚光透镜中穿过后直接向外发射提供照明,本发明对此不作限制。
参考图4,在一些实施例中,探测组件包括发射模块510和接收模块520,发射模块510与光传输部件200的另一端相连接,用于将光传输部件200传输的探测用光向外发射,接收模块520用于接收探测用光的反射光。
具体的,发射模块510向外发射的探测用光遇到物体时可被物体表面反射,反射光被接收模块520接收后,根据接收到的反射光的入射角度可判断出物体相对于探测组件的方位,根据接收反射光与发射探测用光之间的时间间隔可计算得出物体与探测组件之间的距离L0。
参考图4,在一些实施例中,发射模块510设于照明组件侧边,且透镜单元340上设有匀光区341用于使发射模块510发射的探测用光均匀匀化成光强分布均匀的光束并以特定的发射角发射出去。具体的,匀光区341可以是在透镜单元340表面单独加工的微结构,探测用光(如红外激光)进入透镜单元340时,该微结构可对探测用光进行光型整形,使从透镜单元340穿出的光线形成光强分布均匀并带有特定视场角的面阵激光面,从而达到对探测用光的光路进行调节的目的。发射模块510可设于照明组件一侧侧边或设于照明组件周围,由于发射模块510与照明组件采用同一个透镜单元340进行光线的调节,从而利用一个透镜单元340可兼容照明和探测功能,可节省元件制造成本,结构组合后更加紧凑。
在一些实施例中,匀光区341设于透镜单元340一侧边缘或环绕透镜单元340设置。采用该设置后,发射模块510也靠近透镜单元340侧边或环绕透镜单元340设置,有利于设备整体的小型化和集约化设计。
在一些实施例中,发射模块510固定于安装壳体310内壁,且发射模块510通过隔断与照明光束隔开。本实施例,设置的隔断隔开了发射模块510与照明光束,发射模块510发射的探测用光与照明光束相互不干涉,从而可 防止光信号的相互干扰降低使用效果。
继续参考图4,在一些实施例中,发射模块510包括一个或多个红外激光器511,红外激光器511通过固定座512固定于安装壳体310内壁,固定座512上设有用于隔开发射模块510与照明光束的隔板5121。如图7所示,多个红外激光器511分别固定于固定座512上,再将固定座512从安装壳体310后端置入安装壳体310内,红外激光器511的前端朝向透镜单元340上的匀光区341,红外激光器511发射的红外激光经匀光区341匀光调节后从透镜单元340穿过并均匀发射出;隔板5121隔开了红外激光器511与照明光束,从而降低了红外激光器511发射的红外激光与照明光束相互干涉的概率,有利于提升使用效果。
红外激光器511可与接收模块520例如红外接收器配合使用。在一个或多个实施例中,接收模块520设于安装壳体310一侧,采用该设置后,接收模块520与照明组件邻近,有利于设备整体的小型化和集约化设计。红外激光器511发射红外激光可以实现红外面阵探测,红外接收器通过接收红外面阵激光的反射光进行探测工作,即组成flash LiDAR(泛光面阵式激光雷达),发射的红外激光可以是光脉冲,也可以是连续波。发射光脉冲时,可对于脉冲的脉宽进行特殊的调制,可保证在多台红外激光器511同时运行的情况下设备之间不互相干扰。
红外激光器511发射的红外激光波长可有多种,优选905nm、940nm或1550nm,经试验,采用905nm和940nm,这个波长的红外激光位于太阳光各波长能量分布的薄弱部分,可以增加***的信噪比;采用1550nm的优势不仅在于其位于太阳光波长能量分布更弱的部分,更在于其对于人眼更加安全,可以进一步提升发射端的功率输出,达到更远的探测距离。
可以理解的是,在其他一些实施例中,探测组件还可采用其他雷达技术方案例如MEMS扫描激光雷达、机械振镜扫描激光雷达、OPA光学相控阵激光雷达等,此处不作限制。
参考图3,在一些实施例中,光传输部件200包括照明传导光纤210和探测传导光纤220;照明传导光纤210两端分别连接照明光源和照明组件,用于将照明用光传输至照明组件,探测传导光纤220两端分别连接探测光源和探测组件,用于将探测用光传输至探测组件。具体的,照明传导光纤210两端可分别与照明组件、光源总成100中的照明光源相耦合,用于传输照明用光;探测传导光纤220两端可分别与探测组件、光源总成100中的探测光源相耦合,用于传输探测用光。在其他一些实施例中,光传输部件200只包括一根光纤,利用光纤中并列设置的多根光导纤维可分别用于传输照明用光及探测用光,此处不作限制。
以上所述实施例的各技术特征可以进行任意的组合,为使描述简洁,未对上述实施例中的各个技术特征所有可能的组合都进行描述,然而,只要这些技术特征的组合不存在矛盾,都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式,其描述较为具体和详细,但并不能因此而理解为对发明专利范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本发明构思的前提下,还可以做出若干变形和改进,这些都属于本发明的保护范围。因此,本发明专利的保护范围应以所附权利要求为准。
