Abstract

本发明涉及一种用于机动车辆的装饰元件，所述装饰元件包括至少一块玻璃板，所述玻璃板在从750至1650nm的波长范围内具有包括在5m‑1与15m‑1之间的吸收系数、并且具有外面和内面。根据本发明，在从750至1650nm的波长范围内的基于红外的遥感装置被置于所述玻璃板的所述内面之后。

Description

用于自主汽车的玻璃
本发明涉及一种包括基于红外的遥感装置并且特别地是LiDAR传感器的玻璃。更特别地，本发明涉及一种待集成到自主汽车中的包括新一代LiDAR传感器的玻璃装饰元件。
用于汽车的玻璃装饰件是指可以添加到汽车内部或外部以增加其吸引力或掩饰汽车的一些不美观部分的物品。存在若干种类型的汽车装饰件。一些装饰件用于保护车辆内部或外部的一些部分免受可能由乘客造成的所不希望的损坏，而其他装饰件仅仅是为了美观。
最流行的装饰元件是铬或塑料装饰件。汽车装饰元件可以由乙烯树脂、人造革、木纹以及皮革制成，或者更一般地由塑料、聚碳酸酯元件制成。这种解决方案通常是美观的、但不允许将一些功能(如“触摸屏功能”…)直接添加到装饰件上。
然而，现今在汽车领域考虑到了越来越多的玻璃装饰元件。例如像，将玻璃装饰元件用作汽车行李箱盖，用于A柱、B柱、C柱、D柱(汽车窗户区域的竖直或近竖直支撑件，所述支撑件在轮廓图中从前向后移动分别被指定为A柱、B柱、C柱或(在较大汽车中)D柱)的盖或仪表板上的内部装饰元件、控制台装饰件、车门装饰件...。如玻璃装饰元件在专利申请EP15 177 303.3、EP 15 177 243.1和EP 16 160 906.0中描述，将其通过引用结合在本说明书中。
因此，在汽车领域中使用玻璃装饰元件提供了添加一些功能如触摸功能的机会，这些功能是塑料或其他经典地使用的材料所不允许的。
另外，现今的趋势是使用越来越多的未来将被完全使用的自主汽车。例如，未来的自主汽车(也被称为无人驾驶汽车(driver lower car)、自我驾驶汽车、机器人汽车)是能够感测其环境并且无需人工输入而导航的车辆。
自主车辆使用雷达、LiDAR(光探测与测距(Light Detection And Ranging)的首字母缩写)、GPS、里程计和计算机视觉来探测周围环境。先进的控制系统解释感知信息，以识别适当的导航路径、以及障碍物和相关标识。自主汽车具有能够分析感知数据以在道路上的不同汽车之间进行区分的控制系统，这对于规划到希望目的地的路径非常有用。
现今，自主汽车包括“蘑菇状”LiDAR传感器，这些传感器全部沿着金属车身冒出。那些“蘑菇”例如置于车顶上或汽车外部后视镜上。除了不美观之外，它们令人印象深刻并且占据了很多空间，这与准备具有非常光滑且弯曲的线条(与外部传感器不兼容)的未来汽车设计的汽车设计师的期望不一致。LiDAR传感器也可以嵌入保险杠或前灯系统中，这暗示着其他缺点如对损坏和外部气候条件的更高的暴露。
因此，对使用令人印象深刻且不美观的LiDAR传感器如用于自主汽车的“蘑菇”或保险杠上的LiDAR的替代物存在需求。
根据本发明，基于红外的遥感装置LiDAR传感器是新一代LIDAR，其基于扫描、旋转、泛光(flashing)或固态LiDAR并且使得能够对车辆周围的环境进行3D测绘。因此，基于IR的传感器允许对车辆的周围环境进行精确测绘，所述测绘用于正确地驱动所述自主汽车并且防止与障碍物的任何碰撞。
LiDAR(也写为Lidar、LIDAR或LADAR)是通过用激光照射目标来测量距离的技术。它们特别是扫描、旋转、泛光或固态LiDAR。扫描或旋转LiDAR是使用移动激光束，而泛光和固态LiDAR发射从物体反射的光脉冲。
因此，现今对基于红外(IR)的遥感装置/传感器存在需求，所述遥感装置/传感器能够对车辆周围的环境进行物体检测和3D测绘，如安装在自主汽车内并且特别是完全集成到汽车上LiDAR。
因此，来自现有技术的解决方案不能应对LiDAR新一代的要求，特别是因为具有集成的LiDAR的玻璃不被认为是可能的解决方案。
目前，不存在允许IR信号以足够强度通过车身或玻璃部件如汽车的挡风玻璃或后窗玻璃的解决方案。
因此，本发明提出了一种解决方案，其中LiDAR新一代传感器可以集成在自主汽车内，所述传感器结合了高探测范围、最小的设计变化以及更高的安全性。
通过以下方式此解决方案是可能的：在汽车玻璃装饰元件上集成LiDAR传感器，所述元件表现出足够的IR透射率来使传感器适当地运行。根据本发明，所述玻璃装饰元件不同于视觉玻璃如挡风玻璃、侧围玻璃…。因此，玻璃装饰元件的规格和需要不同于视觉嵌装玻璃的那些。
为简单起见，在以下说明书中的玻璃板的编号是指常规地用于嵌装玻璃的编号命名。因此，与车辆外的环境接触的嵌装玻璃的面被称为侧面1，并且与内部介质(也就是说客厢)接触的表面被称为面2。对于层压式嵌装玻璃，与车辆的外部环境接触的玻璃板被称为侧面1，并且与内部部分即客厢接触的表面被称为面4。
为了避免疑问，术语“外部”和“内部”是指在车辆中安装期间玻璃装饰元件的取向。
同样为了避免疑问，本发明适用于所有运输工具，如汽车、火车、飞机......，而且适用于其他交通工具，像无人机...。
因此，本发明涉及一种用于机动车辆的玻璃装饰元件，所述玻璃装饰元件包括至少一块玻璃板，所述玻璃板在从750至1650nm的波长范围内具有包括在5m-1与15m-1之间的吸收系数、并且具有外面和内面。
根据本发明，在从750至1650nm的波长范围内运行的基于红外的遥感装置被置于玻璃板的内面之后。
根据本发明的优选的实施例，玻璃装饰元件包括置于玻璃板的内面之后的在从750至1000nm的波长范围内的基于红外的遥感装置。
根据本发明，所述玻璃板在从750至1650nm的波长范围内具有包括在5m-1与15m-1之间的吸收系数。为了量化玻璃板在红外范围内的低吸收，在本说明书中，使用在从750至1650nm的波长范围内的吸收系数。所述吸收系数是由在给定环境中的吸收度与电磁辐射经过的光程长度之间的比率定义的。它以m-1表示。因此它独立于所述材料的厚度，但它是所吸收辐射的波长以及所述材料的化学性质的函数。
在玻璃的情况下，在选定波长λ的吸收系数(μ)可以从透射率(T)的测量值以及所述材料的折射率n计算(thick＝厚度)，n、ρ和T的值是选定波长λ的函数：
其中，ρ＝(n-1)2/(n+1)2。
与常规玻璃(如所述的“透明玻璃”，对于其，此系数约为30m-1数量级)相比，根据本发明的玻璃板优选在750-1650nm的波长范围(通常用于涉及本发明的光学技术中)内具有非常低的吸收系数。特别地，根据本发明的玻璃板在从750至1650nm的波长范围内具有包括在5m-1与15m-1之间的吸收系数。
优选地，所述玻璃板在从750至1650nm的波长范围内具有包括在5m-1与10m-1之间的吸收系数。
根据本发明的优选的实施例，玻璃板在750至1000nm的波长范围内具有吸收系数。
低吸收呈现出额外的优点，即最终的IR透射率受材料中光程的影响较小。其意指对于具有高张角的大视野(FOV)传感器，在各种角度下感知的强度(在不同区域中是图像)将更均匀，尤其是当传感器光学联接到嵌装玻璃时。
因此，当自主车辆遇到不适合自主操作的出乎意料的驾驶环境如道路建设或障碍时，通过根据本发明的嵌装玻璃车辆传感器可以捕获关于车辆和出乎意料的驾驶环境的数据。捕获的数据可被发送至远程操作员或中央智能单元。远程操作员或单元可以操作车辆或者向自主车辆发出命令以在各种车辆系统上执行。可以优化发送至远程操作员/单元的捕获数据以节约带宽，如通过发送捕获数据的有限子集。
根据本发明的一个优选的实施例，玻璃装饰元件是外部玻璃装饰元件。更特别地，所述外部玻璃装饰元件是用于车辆的A柱、B柱和C柱或行李箱盖的玻璃装饰元件。
根据本发明的另一个实施例，所述外部玻璃装饰元件可以是布置在侧面中并且更特别地布置在车辆的边缘或门上的玻璃装饰元件。
因此，LiDAR可以从车辆的每一侧捕获图像和数据。
更优选地，自主汽车提供有根据本发明的外部玻璃装饰件和嵌装玻璃(如也带有集成的LiDAR的挡风玻璃、侧围玻璃、后窗玻璃)以便覆盖汽车的所有侧面并且对汽车周围进行测绘。
根据本发明的一个实施例，根据本发明的玻璃装饰元件还可以用于覆盖集成到汽车保险杠中的LiDAR。因此，所述LiDAR受到保护而不降低LiDAR功能、性能。
根据本发明，所述玻璃板由可属于不同类别的玻璃制成，所述玻璃具有在从750至1650nm的波长范围内具有包括在5m-1与15m-1之间的吸收系数的特质。因此，所述玻璃可以是钠钙硅型玻璃、硅铝酸盐、硼硅酸盐...。
优选地，具有高水平近红外辐射透射率的玻璃板是超透明玻璃。
优选地，本发明的基础玻璃组成包含以玻璃的重量百分比表示的总含量的以下项：
