具体实施方式
下面通过实施例，并结合附图，对本公开的技术方案作进一步具体的说明。在说明书中，相同或相似的附图标号指示相同或相似的部件。下述参照附图对本公开实施方式的说明旨在对本公开的总体发明构思进行解释，而不应当理解为对本公开的一种限制。
另外，在下面的详细描述中，为便于解释，阐述了许多具体的细节以提供对本披露实施例的全面理解。然而明显地，一个或多个实施例在没有这些具体细节的情况下也可以被实施。
应该理解的是，尽管在这里可使用术语第一、第二等来描述不同的元件，但是这些元件不应受这些术语的限制。这些术语仅是用来将一个元件与另一个元件区分开来。例如，在不脱离示例实施例的范围的情况下，第一元件可以被命名为第二元件，类似地，第二元件可以被命名为第一元件。如在这里使用的术语“和/或”包括一个或多个相关所列的项目的任意组合和所有组合。
本文使用的术语仅是为了描述特定实施例的目的，而不意图限制示例实施例。如这里所使用的，除非上下文另外明确指出，否则单数形式也意图包括复数形式。还将理解的是，当在此使用术语“包含”和/或“包括”时，说明存在所述特征、整体、步骤、操作、元件和/或组件，但不排除存在或附加一个或多个其它特征、整体、步骤、操作、元件、组件和/或它们的组合。
在本文中，除非另有特别说明，表述“车辆”包括可以移动的交通工具，包括但不限于，两轮机动车，三轮机动车，四轮机动车，火车等。
表述“光强”，也称为光照强度，指单位面积上所接受可见光的光通量，其单位为勒克斯(lux或lx)，用于指示光照的强弱和物体表面积被照明程度的量。
发明人经研究发现，随着汽车智能化、电动化和网联化的发展，智能座舱技术已经成为汽车的主要部分。智能座舱的一个重要组成部分是汽车玻璃，包括前后挡风玻璃、天窗、侧窗和遮阳板等。随着技术的发展和用户需求的不断提升， 车载玻璃需要具备越来越多的功能，例如，车载玻璃除常规的透光功能之外，还需要具备显示画面、与用户交互等功能。具有显示、交互等功能的车载玻璃需要综合采用薄膜晶体管阵列、显示控制、多色像素等技术，所以，该车载玻璃的成本比传统的车载玻璃的成本高。为了满足用户需求，同时兼顾成本，当前落地性较强的技术方向为调光玻璃。也就是说，将调光玻璃用于车辆中，在实现常规的透光功能之外，还实现显示画面、与用户交互等功能。
应用于调光玻璃中的技术可以包括PDLC(聚合物分散液晶)、EC(电致变色)和SPD(悬浮粒子)技术。
PDLC调光玻璃投入量产的时间较早，成本相对低廉，可实现透明和雾化两种效果。在通电状态下，聚合物分散液晶分子有序排列，光线直接穿过玻璃；在断电状态下，聚合物分散液晶分子无序排列，光线发生散射，从而形成雾化效果。PDLC调光玻璃通常颜色偏白，雾化后可呈现柔和的自然光。
SPD调光玻璃中的悬浮粒子可吸收99％以上的可见光。在断电状态下，玻璃呈雾化状态；在通电状态下，悬浮粒子发生取向(有序)排列，允许光线透过。SPD调光玻璃实现了光线连续可调。受限于悬浮粒子特性，SPD调光玻璃需要使用110V电压，需配套更完善的安全措施，这直接抬高了成本。SPD调光玻璃一般为蓝色，观感有别于PDLC玻璃。
EC调光玻璃中，利用材料和电场所产生的颜色变化，实现玻璃透光度的调整。EC调光玻璃由离子储存层、固态电解质和电致变色层三部分组成，具备低电压、低雾度、断电记忆的特点。在电场作用下，电致变色层的反射率、透过率和吸收率发生变化，进而改变通过玻璃的光线。颜色方面，EC调光玻璃主要有灰色和蓝色两种。
在本公开的实施例中，所述调光玻璃可以包括染料液晶调光玻璃。
图1是根据本公开的一些示例性实施例的调光玻璃的平面示意图，图2是根据本公开的一些示例性实施例的调光玻璃沿图1中的线AA’截取的截面图。
结合参照图1和图2，调光玻璃10可以包括相对设置的第一调光基板1和第二调光基板2、以及夹设在第一调光基板1与第二调光基板2之间的调光组件3。
第一调光基板1可以包括第一衬底基板11、第一电极12、第一绝缘层13和第一取向层14。第一电极12、第一绝缘层13和第一取向层14依次设置在第一 衬底基板11上。
第二调光基板2可以包括第二衬底基板21、第二电极22和第二取向层24。第二电极22和第二取向层24依次设置在第二衬底基板21上。
调光玻璃10还可以包括隔垫物32，以起到支撑作用。可选地，隔垫物32可以为球形隔垫物32、柱状隔垫物32或其他形状隔垫物32，隔垫物32可以由透明材料或非透明材料制成。
例如，第一衬底基板11和第二衬底基板21可以分别为透明玻璃基板。例如，该调光玻璃10可以应用于建筑、交通及室内装修设计等领域，以实现透明态与非透明态(例如暗态或雾态)之间的切换，玻璃的透明度的连续变化。
例如，第一电极12和第二电极22可以分别为透明电极，例如，它们可以由诸如氧化铟锡(ITO)等的透明导电材料构成。
在本公开的一些实施例中，调光组件3可以包括液晶层，例如，该液晶层可以包括染料液晶，具体地，该液晶层可以包括液晶分子以及与液晶分子混合的色性染料分子。例如，色性染料分子可以为二向色性染料分子。
第一调光基板1包括的第一电极12包括多个第一子电极121，多个第一子电极121间隔地布置在第一衬底基板11上。即，第一电极12在第一衬底基板11上的正投影形成为多个间隔分布的条形形状。应该理解，每一个第一子电极121均为透明第一子电极121，例如，每一个第一子电极121均由诸如ITO的透明导电材料构成。
参照图1和图2，调光玻璃10还可以包括设置在第一衬底基板11上的多条走线15。示例性地，多条走线可以分别与多个第一子电极121一一对应。例如，每一条走线可以是导电材料构成的导电走线。
参照图1和图2，调光玻璃10还可以包括例如IC的驱动电路16，驱动电路16用于提供电信号。具体地，多条走线可以分别将对应的第一子电极121电连接至例如IC的驱动电路16，这样，驱动电路16提供的控制信号可以分别供应至多个第一子电极121。
第二调光基板2包括的第二电极22可以为面状电极，即，第二电极22在第二衬底基板21上的正投影形成为一个连续分布的平面图形形状，例如，在图1的实施例中，第二电极22在第二衬底基板21上的正投影形成为一个完整的矩形。
示例性地，如图1所示，第一电极12在第一衬底基板11上的正投影落入第 二电极22在第一衬底基板11上的正投影内。
应该理解，第二电极22也可以通过导电结构(如走线)电连接至例如IC的驱动电路16，这样，驱动电路16提供的控制信号可以供应至第二电极22。
在本公开实施例提供的调光玻璃中，在不对第一电极12和第二电极22施加电压时，第一电极12和第二电极22之间不产生电场，调光组件3中的液晶分子和色性染料分子均垂直取向，不对光进行吸收，使得调光玻璃呈现透光状态(即完全透明态)。在对第一电极12和第二电极22施加预定电压时，第一电极12和第二电极22之间产生电场，液晶层3中的液晶分子和色性染料分子发生偏转，液晶分子在电场作用下水平排列，诱导色性染料分子水平排列，起到吸光作用，使得调光玻璃呈现不透光状态(即完全暗态)，或者，调光玻璃呈现完全暗态与完全透明态之间的透明度。
在该实施例中，以染料液晶为例对本公开实施例提供的调光玻璃进行了说明，应该理解的是，本公开实施例提供的调光玻璃不局限于染料液晶调光玻璃，还可以包括其他类型的调光玻璃，包括但不限于，PDLC调光玻璃，SPD调光玻璃，EC调光玻璃等。
发明人发现，汽车通常具有至少三种行驶模式：运动模式、普通模式和节能模式。运动模式(Sport)：更具激进性的驾驶风格，更好的动力，更快的速度。运动模式通过提高发动机转速或快速降挡使车辆瞬间爆发出更大的动力。普通模式(Normal)：又称为舒适模式或休闲模式，普通模式是为了保证动力不变，也为了获得更好的燃油经济性，而使用普通模式下的控制，汽车的油门响应最平衡，操控感更简单舒适，容易上手。节能模式(ECO)：又称为经济模式，更经济省油的驾驶方式，适合日常通勤，节能模式是以合理的挡位控制发动机转速，减少不必要的燃油消耗，追求经济的燃油消耗。
在本公开的实施例中，将调光玻璃技术应用于车辆中，具体地，车辆的前后挡风玻璃、天窗玻璃、侧窗玻璃和遮阳板玻璃中的至少一个玻璃可以为上述的调光玻璃。基于此，通过调节该调光玻璃的光线透过率，可以实现提供安全性、保护隐私的效果。例如，在车辆转弯、变道或高速行驶的场景中，可以提高调光玻璃的光线透过率，这样，驾驶员可以更清晰地观察到外界环境，从而可以提高驾驶安全性；在车内有人员休息或车辆附近有其他车辆的场景中，可以降低调光玻璃的光线透过率，这样，可以提高车内人员的隐私保护性。
一方面，提高安全性需要提高调光玻璃的光线透过率，另一方面，保护隐私需要降低调光玻璃的光线透过率，两者对调光玻璃的要求相反。如何智能地调节调光玻璃，使得用户兼顾提高安全性和保护隐私的需求，是应用于车载领域的调光玻璃需要解决的问题之一。
本公开的实施例提供了一种用于车辆的调光玻璃系统的控制方法和系统。所述控制方法包括：获取用户从预设的m个车辆行驶模式中选择的一个车辆行驶模式，其中，m为大于等于2的正整数；根据车辆行驶模式与调光模式之间的映射关系，确定与用户选择的车辆行驶模式对应的调光模式，其中，所述车辆行驶模式与调光模式之间的映射关系包括预设的m个车辆行驶模式与n个调光模式之间的映射关系；以及根据所述调光模式对所述车辆的调光玻璃系统进行控制。
在本公开的实施例中，根据不同的车辆行驶模式，对调光玻璃的调光模式进行不同的设置，能够兼顾提高安全性和保护隐私的需求，从而能够给用户提供更好的驾乘体验。
需要说明的是，在本文中，除非另有特别说明，“透过率调整信息”包括调整光线透过率的大小和变换速率中的至少一个。
需要说明的是，在本文中，除非另有特别说明，“对所述车辆的调光玻璃系统进行控制”包括：调光玻璃的光线透过率控制、待调光的玻璃的选择控制、调光玻璃的分区控制等。
下面，结合附图进一步详细描述本公开的实施例。
在本公开的一些实施例中，提供了一种用于车辆的调光玻璃系统。图3是根据本公开的示例性实施例的用于车辆的调光玻璃系统的结构示意图。结合参照图1～图3，该调光玻璃系统100包括调光玻璃10和控制器4。其中，调光玻璃可以基于如上图1～图2的一个或多个实施例实现，并安装于车辆上；以及控制器4与所述调光玻璃10的第一电极12和第二电极22电连接。例如，控制器4还可以与车辆的车机系统5连接。控制器4可以通过LIN或CAN总线与车辆的车机系统5连接。
例如，在图3所示的实施例中，示意性示出了与车机系统5连接的光强传感器61、车速传感器62、雷达传感器63和座椅控制器64，与座椅控制器64连接的座椅65。
在下文中，将结合具体的控制方法进一步描述控制器4的工作过程。
图4是根据本公开的一些示例性实施例的调光玻璃系统的控制方法的流程图。所述控制方法包括步骤S410～S460。
在步骤S410中，获取用户从预设的m个车辆行驶模式中选择的一个车辆行驶模式，其中，m为大于等于2的正整数。
在步骤S420中，根据车辆行驶模式与调光模式之间的映射关系，确定与用户选择的车辆行驶模式对应的调光模式，其中，所述车辆行驶模式与调光模式之间的映射关系包括预设的m个车辆行驶模式与n个调光模式之间的映射关系，其中，n为大于等于2的正整数。
在一些实施例中，m可以等于n，即，车辆行驶模式和调光模式的数量相同，m个车辆行驶模式和n个调光模式可以分别一一对应。在该实施例中，可以分别为每一个车辆行驶模式确定一个对应的调光模式，有利于实现为各个车辆行驶模式量身定制调光模式，实现各个车辆行驶模式下调光模式的个性化定制。
在一些实施例中，m可以大于n，即，车辆行驶模式的数量大于调光模式的数量。例如，车辆可以包括3个车辆行驶模式：运动模式、普通模式和节能模式，该车辆可以包括2个调光模式，例如，运动模式对应一个调光模式，普通模式和节能模式可以共用一个调光模式。在该实施例中，部分车辆行驶模式可以共用一个调光模式，可以减少调光模式的数量，有利于用户操作的便利化。
在一些实施例中，m可以小于n，即，车辆行驶模式的数量小于调光模式的数量。例如，车辆可以包括3个车辆行驶模式：运动模式、普通模式和节能模式，该车辆可以包括4个调光模式，例如，运动模式对应2个调光模式，普通模式和节能模式分别对应一个调光模式。在该实施例中，部分车辆行驶模式可以对应2个以上的调光模式，可以实现部分车辆行驶模式下调光模式的更精细的控制，有利于满足用户的多元化需求。
在步骤S430中，根据所述调光模式对所述车辆的调光玻璃系统进行控制。
在本公开的一些示例性实施例中，所述n个调光模式分别具有各自固定的光线透过率或光线透过率范围。也就是说，所述n个调光模式分别对应固定的光线透过率或光线透过率范围。当用户选择某一车辆行驶模式后，通过该车辆行驶模式映射某一调光模式，通过该某一调光模式确定出其对应的固定的光线透过率或光线透过率范围。
在该实施例中，步骤S430中，所述根据调光模式对所述车辆的调光玻璃系 统进行控制包括：根据所述调光模式具有的固定的光线透过率或光线透过率范围，对所述车辆的调光玻璃系统进行控制。
在一些示例性的实施例中，所述m个车辆行驶模式包括第一车辆行驶模式。例如，第一车辆行驶模式可以是运动模式。在该实施例中，所述n个调光模式包括第一调光模式，所述车辆行驶模式与调光模式之间的映射关系包括所述第一车辆行驶模式与所述第一调光模式之间的映射关系。
在一些示例性的实施例中，所述m个车辆行驶模式还包括第二行驶模式。例如，第二行驶模式可以是普通模式。在该实施例中，所述n个调光模式还包括第二调光模式，所述车辆行驶模式与调光模式之间的映射关系还包括所述第二车辆行驶模式与所述第二调光模式之间的映射关系。
在一些示例性的实施例中，所述第一调光模式中光线透过率或光线透过率范围高于所述第二调光模式中的光线透过率或光线透过率范围。通过这样的设计，可以使得运动模式的光线透过率高于普通模式的光线透过率，从而能够实现运动模式下的安全性和普通模式下的隐私保护兼顾。
在一些示例性的实施例中，所述m个车辆行驶模式还包括第三行驶模式。例如，第三行驶模式可以是节能模式。在该实施例中，所述n个调光模式还包括第三调光模式，所述车辆行驶模式与调光模式之间的映射关系还包括所述第三车辆行驶模式与所述第三调光模式之间的映射关系。
在一些示例性的实施例中，所述第三调光模式中的光线透过率或光线透过率范围介于所述第一调光模式中的光线透过率或光线透过率范围和所述第二调光模式中的光线透过率或光线透过率范围之间。
在步骤S440中，检测所述车辆的安全相关事件和隐私相关事件中的至少一个事件。
在步骤S450中，根据用户选择的调光模式和检测到的至少一个事件，确定所述车辆上的调光玻璃的透过率调整信息。
在步骤S460中，根据所述透过率调整信息对所述调光玻璃的光线透过率实施调整。
在本公开的实施例中，在所述n个调光模式中的至少两个调光模式中，安全相关事件和隐私相关事件的优先级不同。
在一些示例性的实施例中，所述m个车辆行驶模式包括第一车辆行驶模式。 例如，第一车辆行驶模式可以是运动模式。在该实施例中，所述n个调光模式包括第一调光模式，所述车辆行驶模式与调光模式之间的映射关系包括所述第一车辆行驶模式与所述第一调光模式之间的映射关系。在所述第一调光模式中，全部安全相关事件的优先级均高于隐私相关事件的优先级。
在一些示例性的实施例中，所述m个车辆行驶模式还包括第二行驶模式。例如，第二行驶模式可以是普通模式。在该实施例中，所述n个调光模式还包括第二调光模式，所述车辆行驶模式与调光模式之间的映射关系还包括所述第二车辆行驶模式与所述第二调光模式之间的映射关系。在所述第二调光模式中，至少一部分隐私相关事件的优先级高于至少一部分安全相关事件的优先级。
在一些示例性的实施例中，所述m个车辆行驶模式包括第三车辆行驶模式。例如，第三车辆行驶模式可以是节能模式。在该实施例中，所述n个调光模式包括第三调光模式，所述车辆行驶模式与调光模式之间的映射关系包括所述第三车辆行驶模式与所述第三调光模式之间的映射关系。在所述第三调光模式中，全部安全相关事件的优先级均高于隐私相关事件的优先级，或者，安全相关事件的优先级和隐私相关事件的优先级可以处于同一等级。
表1示例性示出了不同车辆行驶模式中的优先级和考虑因素。结合参照表1和图4，示例性地，第一车辆行驶模式可以是运动模式，第二车辆行驶模式可以是普通模式，第三车辆行驶模式可以是节能模式。所述安全相关事件包括以下事件中的至少一个：车辆转弯、车辆变道和车速超过车速阈值。所述隐私相关事件包括以下事件中的至少一个：车辆内乘客处于休息状态、所述车辆附近有其他车辆。例如，所述车辆附近有其他车辆可以包括以下情况中的至少一个：对于行驶中的车辆，在该车辆的相邻车道中存在并排行驶的其他车辆；对于停在车位的车辆，在该车辆的相邻车位中存在并排停放的其他车辆。
在第一车辆行驶模式(即运动模式)中，由于车辆驾驶风格相对激进，所以，将安全性的优先级提高，如表1所示，安全相关事件的优先级高于隐私相关事件的优先级。在第二车辆行驶模式(即普通模式)中，用户追求相对舒适的驾乘体验，所以，将部分隐私相关事件的优先级提高，如表1所示，部分安全相关事件的优先级低于隐私相关事件的优先级。
表1
在该实施例中，通过根据不同的车辆行驶模式制定不同的安全或隐私相关事件的优先级，可以兼顾提高安全性和保护隐私的用户需求，从而可以给用户提供更好的驾乘体验。
图5是根据本公开的一些示例性实施例的调光玻璃系统的控制方法的流程图。所述控制方法包括步骤S510～S540。
在步骤S510中，用户可以选择车辆行驶模式。
具体地，车辆的车机系统可以提供用户选择界面，用户可以为不同的车辆行驶模式设置不同的调光模式，车机系统建立车辆行驶模式和调光模式之间的映射关系。例如，在不同的调光模式中，调光玻璃的初始光线透过率可以设置为不同。具体地，可以通过滑动调光玻璃控制条或旋转调光玻璃旋钮来设置不同的调光模式中的调光玻璃的初始光线透过率。
在步骤S520中，当用户选择运动模式时，设置调光玻璃进行第一调光模式。例如，在第一调光模式下，调光玻璃的初始光线透过率较高，以便提供更好的视野。
在步骤S530中，当用户选择普通模式时，设置调光玻璃进行第二调光模式。例如，在第二调光模式下，调光玻璃的初始光线透过率较低，例如，低于第一调光模式下调光玻璃的初始光线透过率，以提供更好的隐私保护。
在步骤S540中，当用户选择节能模式时，设置调光玻璃进行第三调光模式。例如，在第三调光模式下，调光玻璃的初始光线透过率适中，例如，所述第三调光模式中的初始光线透过率介于所述第一调光模式中的初始光线透过率和所述第二调光模式中的初始光线透过率之间。
基于此，在本公开的一些示例性实施例中，所述控制方法还可以包括：根据确定出的调光模式，确定所述调光玻璃的初始光线透过率。例如，所述第一调光模式中的初始光线透过率高于所述第二调光模式中的初始光线透过率。所述第三调光模式中的初始光线透过率介于所述第一调光模式中的初始光线透过率和所述第二调光模式中的初始光线透过率之间。
图6是根据本公开的一些示例性实施例的调光玻璃系统的控制方法在运动模式下的流程图。在运动模式下，所述控制方法包括步骤S610～S650。
参照图6，在步骤S610中，获取用户选择的车辆行驶模式为第一车辆行驶模式，即运动模式。
在运动模式中，全部安全相关事件的优先级高于隐私相关事件的优先级。在该实施例中，首先对安全相关事件进行检测和判断。
在步骤S620中，根据确定出的第一调光模式，对全部安全相关事件进行判断。
在步骤S630中，响应于至少一个安全相关事件满足安全保护触发条件，提高至少一个调光玻璃的光线透过率。
然后，在对全部安全相关事件进行判断后，可以对隐私相关事件进行检测和判断。
在步骤S640中，响应于全部安全相关事件均未满足安全触发条件，对隐私相关事件进行判断。
在步骤S650中，响应于至少一个隐私相关事件满足隐私保护触发条件，降低至少一个调光玻璃的光线透过率。
图7是根据本公开的一些示例性实施例的调光玻璃系统的控制方法在运动模式下的示例性流程图。在运动模式下，所述控制方法包括步骤S710～S790。
参照图7，在步骤S710中，获取用户选择的车辆行驶模式为第一车辆行驶模式，即运动模式。
在运动模式中，全部安全相关事件的优先级高于隐私相关事件的优先级。在该实施例中，首先对安全相关事件进行检测和判断。
在步骤S730中，根据确定出的第一调光模式，对第一安全相关事件进行判断。例如，所述第一安全相关事件可以是车辆转弯，即，在该步骤中，可以判断车辆是否转弯。
在步骤S740中，响应于第一安全相关事件满足安全保护触发条件，提高至少一个调光玻璃的光线透过率。例如，响应于车辆在转弯，提高位于车辆前排侧窗的调光玻璃的光线透过率。这样，可以提高转弯时的驾驶安全性。
在步骤S760中，响应于第一安全相关事件未满足安全保护触发条件，对第二安全相关事件进行判断。例如，所述第二安全相关事件块可以是车速超过车速阈值。在该步骤中，响应于车辆未在转弯，判断车速是否超过预设的车速阈值。
在步骤S770中，响应于第二安全相关事件满足安全保护触发条件，提高至少一个调光玻璃的光线透过率。例如，响应于车速超过车速阈值，即车辆在高速行驶，提高位于车辆前排侧窗的调光玻璃的光线透过率，以及提高位于乘客附近的侧窗的调光玻璃的光线透过率。这样，可以提高高速行驶时的驾驶安全性。
在步骤S780中，响应于第二安全相关事件未满足安全保护触发条件，对至少一个隐私相关事件进行判断。例如，响应于车速未超过车速阈值，可以判断车辆附近是否存在其他车辆。
在步骤S790中，响应于至少一个隐私相关事件满足隐私保护触发条件，降低至少一个调光玻璃的光线透过率。例如，响应于车辆附近存在其他车辆，可以降低至少一个调光玻璃的光线透过率，例如，降低位于车辆前排侧窗的调光玻璃的光线透过率，以及降低位于乘客附近的侧窗的调光玻璃的光线透过率。这样，可以保护车内人员的隐私。
在本公开的实施例中，在运动模式中，由于驾驶风格相对激进，所以优先考虑安全相关事件，在保证驾驶安全性的情况下，兼顾保护隐私，从而实现了提高安全性和保护隐私的效果。
继续参照图7，可选地，在本公开的一些示例性实施例中，在步骤S720中，可以根据第一调光模式和所述车辆所处的环境，确定所述调光玻璃的初始光线透过率。例如，可以结合第一调光模式以及天气、光照强度、时间等环境因素，确定调光玻璃的初始光线透过率。
继续参照图7，可选地，在本公开的一些示例性实施例中，所述控制方法还可以包括步骤S7201和S7202。在步骤S7201中，可以持续检测所述车辆所处的环境是否发生变化，例如，可以持续检测天气、光照强度、时间等环境因素是否发生变化。在步骤S7202中，响应于所述车辆所处的环境发生了变化，调整所述调光玻璃的初始光线透过率。
继续参照图7，可选地，在本公开的一些示例性实施例中，在步骤S750中，所述方法还包括：获取所述车辆内人员的分布位置。
在步骤S770和步骤S790中，可以根据所述车辆内人员的分布位置，确定需要实施光线透过率调整的调光玻璃。
例如，所述响应于第一安全相关事件满足安全保护触发条件，提高至少一个调光玻璃的光线透过率，包括：响应于第一安全相关事件满足安全保护触发条件，提高位于所述车辆前排的侧窗的调光玻璃的光线透过率。
例如，所述响应于第二安全相关事件满足安全保护触发条件，提高至少一个调光玻璃的光线透过率，包括：响应于第二安全相关事件满足安全保护触发条件，提高位于所述车辆的驾驶员侧的侧窗和位于所述车辆内的乘客附近的侧窗的调光玻璃的光线透过率。
例如，所述降低至少一个调光玻璃的光线透过率包括：降低位于所述车辆的驾驶员侧的侧窗和位于所述车辆内的乘客附近的侧窗的调光玻璃的光线透过率。
在本公开的一些实施例中，可以根据所述车辆内人员的分布位置，对所述车辆内人员的位置附近的调光玻璃的光线透过率进行调整。例如，当车辆内后排左侧位置上有乘客时，可以确定后排左侧车窗的玻璃为需要实施光线透过率调整的玻璃；当车辆内后排右侧位置上有乘客时，可以确定后排右侧车窗的玻璃为需要实施光线透过率调整的玻璃；当车辆内后排中间位置上有乘客时，可以确定后排两侧车窗的玻璃为需要实施光线透过率调整的玻璃。
在本公开的一些实施例中，根据所述车辆内人员的分布位置调整光线透过率时，还需要结合天气、光照强度等环境因素。例如，在以遮阳为目的的模式下，“根据分布位置确定光线透过率”可以包括调整光线透过率，使车辆内人员附近的玻璃处于低透过率，从而减小外界光照对车辆内人员的照射。在部分保护安全驾驶的模式下，例如，为避免外界强光刺激驾驶员的眼睛，可以降低驾驶员侧车窗玻璃的光线透过率。在以方便车辆内人员观察外界环境为目的的模式下，例如，可以是方便司机从昏暗的地库开出时观察周围车辆、可以是后座乘客便于观光旅途风景，此时可以提高车辆内人员附近的玻璃的光线透过率。

参照图11，在步骤S1110中，获取用户选择的车辆行驶模式为第三车辆行驶模式，即节能模式。
在步骤S1120中，根据确定出的第三调光模式，对至少一个安全相关事件进行判断。例如，所述至少一个安全相关事件可以是车辆转弯，即，在该步骤中，可以判断车辆是否转弯。
在步骤S1130中，响应于至少一个安全相关事件满足安全保护触发条件，提高至少一个调光玻璃的光线透过率。例如，响应于车辆在转弯，提高位于车辆前排侧窗的调光玻璃的光线透过率。这样，可以提高转弯时的驾驶安全性。
表2示意性示出了在天窗不同的开合状态下车辆内部光照强度分布的实测数据。如表2所示，前排的光照强度基本不受天窗开合的影响，后排的光照强度受天窗开合的影响较大。车内光照强度分布不均，前后排光照强度相差可以到达7倍，驾驶员和乘客的体验差别很大。在前排，当车辆外界环境的光照强度为15000时，车内侧视方向为3000，车内、车外的对比度为1：5；在后排，当车辆 外界环境的光照强度为16000时，车内前视方向为700(关闭天窗)，车内、车外的对比度1∶25，隐私的保护性好。
表2车内光照强度分布
表3示意性示出了前后排的隐私保护程度的实测数据。如表3所示，侧视方向看，前排光照强度为3000，后排光照强度为650，即，在车外1-2米位置观察，能初步看到前排的情况，包括是否有人、性别、座椅的颜色等，无法看到后排的情况，隐私的保护性较好。
表3前后排光照强度不同，导致隐私的保护程度不同
通过实测数据，发明人经过研究，得出如下结论：(1)安全主要和前排侧窗相关，特别是转弯和变道等场景下需要观察侧窗；(2)隐私主要和后排侧窗、后挡风玻璃相关，也可以和前排侧窗相关；当需要对前排进行隐私保护时，前排侧窗需要选择超低透过率的玻璃，且透过率小于后排玻璃的透过率。
