具体实施方式
参照图1，一种基于OLED的动态指示系统，包括：
无钥匙进入及启动系统，用于进行钥匙的合法性认证以及车辆上下电控制；
整车控制器，用于在车辆上电通过后使能整车高压上电，使车辆进入行车准备状态；
车身控制器，用于在钥匙的合法性认证成功后输出位置灯控制信号；
大屏显示系统，用于在整车高压上电后输出OLED动态效果信号；
OLED控制器，用于根据位置灯控制信号、行车准备状态信号和OLED动态效果信号输出多个OLED片驱动信号；
OLED屏体，用于根据所述多个OLED片驱动信号分别使能OLED屏体的OLED片进行第一动态指示模式的动态指示，其中，一个OLED片驱动信号独立控制OLED屏体中的一片OLED片；
所述无钥匙进入及启动系统的输出端分别与整车控制器的第一输入端和车身控制器的第一输入端和OLED控制器的第一输入端连接，所述整车控制器的第一输出端连接车身控制器的第二输入端，所述整车控制器的第二输出端连接OLED控制器的第二输入端，所述整车控制器的第三输出端连接大屏显示系统的输入端，所述车身控制器的输出端连接OLED控制器的第三输入端，所述大屏显示系统的输出端连接OLED控制器的第四输入端，所述OLED控制器的所有输出端均与OLED屏体的输入端连接。
目前的汽车尾部位置灯仍较多采用LED颗粒光源。为了满足法律法规对汽车尾灯发光的要求，汽车尾部位置灯会采用LED组列方式，通过一定规律的排布组列，可以实现位置灯造型的不同变化。但是LED颗粒光源的发光亮度有限，在没有布置铝制反射网等聚光零件且LED数量较少时，汽车尾部位置灯很难达到法律法规的发光要求，所以其在控制上采用简单控制方式，如图2所示。图2中，K为位置灯开关。如图2所示，该简单控制方式当车身控制器(BCM)输出位置灯控制信号后，尾灯LED驱动器将位置灯控制信号转化为可驱动LED组列中所有LED发光单元的信号。然而这种控制方式的逻辑较为简单，只能对LED组列进行整体控制，无法对LED组列中的每个LED发光单元进行独立控制，功能单一，不够智能化。
为此，可以使用OLED发光屏片来取代LED颗粒光源，通过采用OLED光源解决了LED光源发光不均匀问题，加上OLED不发热的特性，也不需要反射结构来保证灯光效果，节省了制作散热及导光结构的工艺成本，简化了车灯的结构设计及组装环节，提高了车灯的可塑性，同时大大丰富了车身的造型，使得车灯造型更加灵活。
如图1所示，该基于OLED的动态指示系统应用了OLED技术，包含有无钥匙进入及启动系统(即PEPS)、一键启动开关、整车控制器(即VCU)、车身控制器(即BCM)、大屏显示系统(即CDU)、OLED控制器和OLED屏体，PEPS通过CAN总线分别与BCM、VCU和OLED控制器连接，OLED屏体由若干个OLED发光屏片(简称OLED片)组成。其中，PEPS管控车辆上下电流程并进行钥匙的合法性认证。整车控制器管控整车高压上电过程，能唤醒BCM和CDU，使车辆进入行车准备状态。整车控制器的输入端还连接有一键启动开关(用于输入硬线启动信号)。图1的系统，当驾驶者携带有进行车辆认证的钥匙，进入车辆钥 匙天线可探测的区域时，如果按动钥匙上的任意按键，会启动车辆PEPS与合法钥匙的认证。钥匙的合法性认证通过后，按压钥匙解锁按钮，解锁车门；接着按压一键启动开关，硬线输入启动信号给整车控制器；整车控制器在车辆上电通过后使能整车高压上电，使车辆进入行车准备状态，同时使能大屏显示系统，唤醒大屏显示系统工作；然后BCM输出位置灯打开信号，激活OLED控制器，唤醒OLED控制器工作。当车辆处于上电模式，车辆尾部位置灯处于打开状态且车速小于120km/h时，若OLED控制器成功接收到大屏控制系统发出的OLED动态效果信号且其信号值为0×6时，OLED控制器使能第一动态指示模式(如自定义模式等)的动态效果。但需要说明的是，OLED控制器只有在进入第一动态指示模式后，才可执行CDU发给OLED控制器的OLED动态效果信号来对每个OLED片进行控制，如未进入第一动态指示模式，则不响应大屏显示系统对OLED片的控制。OLED控制器针对每一片OLED发光片有单独驱动，可控制每片OLED片单独点亮，同时也能实现亮度的调节。
由此可见，本实施例OLED控制器在被激活后还将结合OLED动态效果信号驱动OLED屏体的每一个OLED片按照第一动态指示模式的点亮逻辑进行点亮，以达到进行第一动态指示模式(包括自定义模式和系统默认模式等)的动态显示的目的，功能更丰富，且增强了人与汽车的交互体验感，智能化程度更高。
参照图1，进一步作为优选的实施方式，还包括一键启动开关，所述一键启动开关用于输出硬线启动信号，所述一键启动开关的输出端与整车控制器的第二输入端连接。
具体地，在钥匙的合法性认证通过后，一键启动开关通过硬线启动信号使能整车控制器高压上电。
进一步作为优选的实施方式，所述OLED屏体包括若干个OLED单元，每个OLED单元包括外圈OLED片和内圈OLED片，所述外圈OLED片的尺寸大于内圈OLED片的尺寸。
具体地，OLED屏体包括若干个OLED单元，每个OLED单元包括外圈OLED片和内圈OLED片，能丰富OLED屏体的OLED片组合方式，更加灵活和多样化。
进一步作为优选的实施方式，所述OLED屏体包括上层OLED片组和下层OLED片组，所述上层OLED片组和下层OLED片组各包括7个依次排列的OLED单元。
具体地，OLED屏体可包括上层OLED片组和下层OLED片组共两层，上层OLED片组和下层OLED片组各可由7个依次连接的OLED单元组成，每个OLED单元均包括外圈OLED片和内圈OLED片。如图3所示，以左尾灯为例，上层OLED片组中，按从左往右的顺序，SW1和SN1分别为第一个OLED单元的外圈OLED片和内圈OLED片，SW2和SN2分别为第二个OLED单元的外圈OLED片和内圈OLED片，SW3和SN3分别为第三个OLED单元的外圈OLED片和内圈OLED片，SW4和SN4分别为第四个OLED单元的外圈OLED片和 内圈OLED片，SW5和SN5分别为第五个OLED单元的外圈OLED片和内圈OLED片，SW6和SN6分别为第六个OLED单元的外圈OLED片和内圈OLED片，SW7和SN7分别为第七个OLED单元的外圈OLED片和内圈OLED片。同理，如图3所示，下层OLED片组中，按从左往右的顺序，XW1和XN1分别为第一个OLED单元的外圈OLED片和内圈OLED片，XW2和XN2分别为第二个OLED单元的外圈OLED片和内圈OLED片，XW3和XN3分别为第三个OLED单元的外圈OLED片和内圈OLED片，XW4和XN4分别为第四个OLED单元的外圈OLED片和内圈OLED片，XW5和XN5分别为第五个OLED单元的外圈OLED片和内圈OLED片，XW6和XN6分别为第六个OLED单元的外圈OLED片和内圈OLED片，XW7和XN7分别为第七个OLED单元的外圈OLED片和内圈OLED片。本发明的外圈OLED片和内圈OLED片可采用图3所示的结构或其他结构。
如图4所示，本发明实施例还提供了一种基于OLED的动态指示方法，包括以下步骤：
S200、分别使能车身控制器输出位置灯控制信号和使能大屏显示系统输出OLED动态效果信号；
S201、根据位置灯控制信号和OLED动态效果信号使能OLED控制器进入第一动态指示模式，从而驱动OLED屏体的OLED片进行第一动态指示模式的动态指示。
具体地，第一动态指示模式可以是用户自定义的动态显示模式(即自定义模式)或系统默认的动态显示模式(即系统默认模式)等，可预先设置或加载，更加灵活和方便。
在需要自定义模式等第一动态指示模式的动态显示效果时，本实施例可通过使能车身控制器输出位置灯控制信号给OLED控制器，激活OLED控制器；同时可通过整车控制器使能大屏显示系统，唤醒大屏显示系统。OLED控制器激活后，可结合大屏显示系统的OLED动态效果信号驱动OLED屏体的每一个OLED片按照第一动态指示模式的点亮逻辑进行点亮，以达到进行第一动态指示模式的动态显示的目的，功能更丰富，且增强了人与汽车的交互体验感，智能化程度更高。
进一步作为优选的实施方式，所述分别使能车身控制器输出位置灯控制信号和使能大屏显示系统输出OLED动态效果信号这一步骤S200，具体包括：
S2001、通过无钥匙进入及启动系统进行钥匙合法认证，并在钥匙合法认证后解锁车门；
S2002、通过一键启动开关输出硬线启动信号给整车控制器；
S2003、通过整车控制器在接收到硬线启动信号后使能整车高压上电，使车辆进入行车准备状态；
S2004、通过车身控制器在车门解锁后输出位置灯控制信号；
S2005、通过整车控制器使能大屏显示系统输出OLED动态效果信号。
具体地，以第一动态指示模式为自定义模式为例，基于图1的系统，本实施例进入自定义模式步骤如下：(1).通过无钥匙进入及启动系统进行钥匙合法认证后，按压钥匙解锁按钮，解锁车门；(2).按压一键启动开关，输入硬线启动信号给整车控制器；(3).整车控制器在车辆上电通过后使能整车高压上电，使电动车进入行车准备状态；整车控制器在车辆上电通过后同时使能车辆大屏显示系统模块唤醒；(4).车身控制器在钥匙解锁成功后输出位置灯控制信号；(5).大屏显示系统输出用于动态点亮OLED片的OLED动态效果信号；(6).OLED控制器根据位置灯控制信号和行车准备状态信号使能启动自定义模式。
进一步作为优选的实施方式，所述根据位置灯控制信号和OLED动态效果信号使能OLED控制器进入第一动态指示模式，从而驱动OLED屏体的OLED片进行第一动态指示模式的动态指示这一步骤S201，具体包括：
当满足第一动态指示模式的开启条件时，使能OLED控制器进入第一动态指示模式；
通过OLED控制器驱动OLED屏体的OLED片按第一动态指示模式的点亮逻辑进行点亮；
其中，第一动态指示模式的开启条件为车辆于处于上电模式，汽车尾部位置灯处于打开状态，车速小于120km/h且OLED控制器成功接收到大屏显示系统信号值为0×6的OLED动态效果信号。
具体地，将大屏显示系统信号值为0×6的OLED动态效果信号作为开启条件之一是为了保证该信号是有效的。这样做可使得OLED控制器只有在进入第一动态指示模式后，才能执行CDU发给OLED控制器的OLED动态效果信号来对每个OLED片进行控制，如未进入第一动态指示模式，则不响应大屏显示系统对OLED片的控制，避免了误操作，更加可靠。
进一步作为优选的实施方式，所述第一动态指示模式为音乐随动模式，所述通过OLED控制器驱动OLED屏体的OLED片按第一动态指示模式的点亮逻辑进行点亮这一步骤，具体包括：
通过OLED控制器接收大屏显示系统发送的音乐随动模式的报文数据；
根据音乐随动模式的报文数据通过OLED控制器控制OLED屏体相应的OLED片点亮，以进行音乐随动显示；
其中，音乐随动模式的报文数据中每个音符对应的OLED片点亮方式采用用户自定义的点亮方式或默认的OLED片点亮方式。
具体地，大屏显示系统上设有OLED片控制页面，用于对OLED屏体的各个OLED片进行控制。图3的OLED屏体对应的OLED片控制页面如图5所示。从图5可以看出，OLED屏体上每一个区域大屏(即每个OLED片对应的大屏部分)都可控，类似于音乐键盘，单击 其中一个音符，OLED屏体中对应的指定区域会点亮，这就实现了OLED片点亮的用户自定义功能。
以第一动态指示模式为自定义模式为例，基于图3和图5，本具体实施例自定义模式的具体实现过程如下：
起始阶段：OLED片控制页面的所有片区全暗(即所有OLED片都熄灭)。
自定义模式的动态指示过程：当满足自定义模式的开启条件(即满足自定义需求)时，动态效果被激活，OLED控制器根据大屏显示系统发送的点亮指令，依次点亮相应OLED片。例如自定义模式为音乐随动模式，大屏显示系统在预设一首歌时将每首歌的音符分解对应OLED片的亮暗变化，大屏显示系统根据音符的变化，通过0X387报文发送点亮指令给OLED控制器。在发送报文时，大屏显示系统可根据音符的时长分析发送的次数，例如某状态持续1s，大屏显示系统发送50次点亮指令。
具体地，假设1、2、3、4、5、6、7代表音阶中的7个基本音级，读音为do、re、mi、fa、sol、la、si，休止符以O表示。每一个音符的时长对应报文发送间隔周期以及报文发送数据(如次数)，分别如下表1和表2所示：
表1 每一个音符对应的报文发送数据

表2 每一个音符的时长对应报文发送间隔周期
Figure PCTCN2019093490-appb-000001
表2中，第一行的数字1、2、3、4、5、6和7代表音符，第一列OLED_SW1LampC md至OLED_XN7LampC md代表OLED片的名称(例如：OLED_SW1LampC md代表图3中的OLED片SW1、OLED_SN1LampC md代表图3中的OLED片SN1……)，第二列的数字1-28代表OLED片的编号，其余表格中的数字代表了OLED片区的亮灭，点亮为1，不亮为0。从表2可得到音符1的二进制编码为1000000100000010000001000000(即第3列表格的数 字)，其转换为16进制后即可得到表1中音符1对应的报文数据0x 02 81 40 00 00 00 00 00，同理表1中其它音符对应的报文数据可以根据表2得出。
OLED控制器接收到报文数据后按表2的方式控制OLED屏体中的相应OLED片点亮，以实现音乐随动的动态显示功能。除了表2的方式之外，自定义模式也可以根据用户喜好来自由控制OLED片的亮暗，实现人机交互的功能。
而退出自定义模式的条件包含以下2个条件中的任一个：1.汽车尾部位置灯关闭；2.车速为零或者车速大于120km/h。
与图4的方法相对应，本发明实施例还提供了一种基于OLED的动态指示系统，包括：
至少一个存储器，用于存储程序；
至少一个处理器，用于执行所述程序以实现所述的基于OLED的动态指示方法。
上述图4所示的方法实施例中的内容均适用于本系统实施例，本系统实施例所具体实现的功能与上述方法实施例相同，并且达到的有益效果与上述方法实施例所达到的有益效果也相同。
与图4的方法相对应，本发明实施例还提供了一种汽车，包括汽车尾部位置灯，所述汽车尾部位置灯包括所述的基于OLED的动态指示系统。
综上所述，本发明应用了基于OLED技术的OLED发光片作为汽车尾部位置灯，并结合汽车其他信号，融合第一动态指示模式的算法提出了一种新的汽车和OLED动态指示系统及方法，不仅能对OLED片组的每个OLED片进行独立控制，而且通过基于第一动态指示模式的算法的动态指示方式实现了自定义的动态指示效果，增加了人与汽车的交互体验感，更加智能化和人性化。
以上是对本发明的较佳实施进行了具体说明，但本发明并不限于所述实施例，熟悉本领域的技术人员在不违背本发明精神的前提下还可做作出种种的等同变形或替换，这些等同的变形或替换均包含在本申请权利要求所限定的范围内。
