在此，还需要说明的一点是，为了避免因不必要的细节而模糊了本公开，在附图中仅仅示出了与根据本公开的方案密切相关的设备结构和/或处理步骤，而省略了与本公开关系不大的其他细节。
<第一实施例>
图1示出了根据本申请的一个实施例的电子设备100的功能模块框图，该电子设备100包括：生成单元101，被配置为基于通过移动智能应用子***和/或车用辅助采集器采集的与车辆有关的信息生成车辆状态消息；以及通信单元102，被配置为通过4G移动通信网络或5G移动通信网络将所述车辆状态消息发送至中心子***和/或路侧单元(Road Side Unit，RSU)。
其中，生成单元101和通信单元102可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片、处理器。并且，应该理解，图1中所示的电子设备中的各个功能单元仅是根据其所实现的具体功能而划分的逻辑模块，而不是用于限制具体的实现方式。
电子设备100例如可以设置在UE侧或者可通信地连接到UE。这里，还应指出，电子设备100可以以芯片级来实现，或者也可以以设备级来实现。例如，电子设备100可以工作为UE本身，并且还可以包括诸如存储器、收发器(图中未示出)等外部设备。存储器可以用于存储用户设备实现各种功能需要执行的程序和相关数据信息。收发器可以包括一个或多个通信接口以支持与不同设备(例如，基站、其他用户设备等等)间的通信，这里不具体限制收发器的实现形式。
例如，电子设备100可以被实现为各种UE。UE可以被实现为移动终端(诸如智能电话、平板个人计算机(PC)、笔记本式PC、便携式游戏终端、便携式/加密狗型移动路由器和数字摄像装置)或者车载终端(诸如汽车导航设备)。UE还可以被实现为执行机器对机器(M2M)通信的终端(也称为机器类型通信(MTC)终端)。此外，UE可以为安装在上述终端中的每个终端上的无线通信模块(诸如包括单个晶片的集成电路模块)。
此外，本文中的电子设备100或包括电子设备100的UE可以被实现为移动智能终端。电子设备100或包括电子设备100的UE可以安装或放置在车辆上，一方面可以采集与车辆有关的信息，另一方面可以通过通用4G或5G接口来向中心子***或RSU提供车辆状态消息。
这样，原来不具备通信能力的非智能网联车辆变得具备4G、5G通用Uu接入能力，增强了用户对车路协同的感知，进而促进V2X终端的渗透率。此外，5G、边缘计算技术的发展也为移动互联网、云计算的发 展提供了坚实的底层技术支撑，实现低延时、广覆盖、高速率、也为在移动智能终端上开展V2X移动互联网应用提供了保障。
图2示出了根据本实施例的面向移动智能终端的车路******架构的示意图。其中，移动智能应用子***作为逻辑单元被引入，其可以通过安装在其上的V2X移动应用程序(APP)或基于APP的其他应用形态来为用户提供V2X服务。例如，在实体层面上，移动智能应用子***可以包括如下之一：智能手机、智能后视镜、智能行车记录仪等，例如，移动智能应用子***可以包括或实现为本实施例的电子设备100。或者，移动智能应用子***也可以通过在车辆的车载信息交互***上安装V2X应用的方式来为用户提供V2X服务。
如图2所示，移动智能应用子***分别通过接口A13、A14与中心子***和多接入边缘计算平台(MEC)通信。此外，移动智能应用子***还通过接口A15与RSU进行通信。在本实施例中，接口A13、A14和A15均基于4G或5G移动通信网络实现。
移动智能应用子***本身可以具有感知功能，来采集与车辆有关的信息，例如车辆特殊事件状态、车辆历史轨迹、路线预测、车身灯光状态、车门后备箱状态等。这些信息例如可以通过移动智能应用子***的移动导航功能、关联车机的APP来提供。此外，与车辆有关的信息还可以包括相对固定的车辆属性类信息，例如车牌信息、车辆类型等，这些信息可以由用户手动输入。
此外，作为补充或替代，还可以通过车用辅助采集器来采集与车辆有关的信息，例如车辆行驶状态信息，包括但不限于车辆速度、行驶方向、车头朝向、发动机转速、油门位置、瞬时油耗、平均油耗、充电状态等等。
生成单元101基于通过移动智能应用子***和/或车用辅助采集器采集的上述各种信息生成车辆状态消息。通信单元102将生成的车辆状态消息发送给中心子***和/或RSU，以告知自身的实时状态，从而支持一系列协同安全应用。
示例性地，车辆状态消息包括车辆基本安全消息和车辆扩展安全消息。其中，车辆基本安全消息用于传递车辆的基本安全状态数据，例如，车辆基本安全消息包括如下中的一个或多个：车辆的速度，车辆的地理 位置，车辆的三轴加速度信息，车辆位置的置信度，车牌信息，车辆类型，车头朝向，时间戳等等。其中，所述车辆自身的行驶数据可以包括以下中的一个或多个：发动机转速，发动机负荷，油门位置，瞬时油耗，平均油耗，充电状态，电池寿命，进气温度。
车辆扩展安全消息例如包括如下中的一个或多个：车辆特殊事件状态，车辆历史轨迹，路线预测，车身灯光状态，车门后备箱状态，车辆自身的行驶数据。车辆扩展安全消息用作车辆基本安全消息的补充，其中，各个信息项都是可选的。
应该理解，以上给出的信息项均是示例，车辆状态消息还可以适当地包括其他与车辆的状态有关的信息项。以下给出车辆状态消息的相应的ASN.1代码的非限制性示例。
[ASN.1代码]
VehicleStatusMessage::＝SEQUENCE{
msgCnt MsgCount,--消息计数器
plateNo OCTET STRING(SIZE(4…16))OPTIONAL,--车牌信息

speed Speed,--车速
heading Heading,--车头朝向
accelSet AccelerationSet4Way,--加速度
vehicleClass VehicleClassification,--车辆类型

…
}
车辆扩展安全消息的ASN.1代码的非限制性示例如下：
[ASN.1代码]
VehicleSafetyExtentions::＝SEQUENCE{

pathHistory PathHistory OPTIONAL,--车辆历史轨迹

engineload Engineload,OPTIONAL,--发动机负荷

…
}
应该注意，以上车辆状态消息中的各个字段均是通过移动智能应用子***和/或车用辅助采集器获取的，并不是传统意义上通过车辆CAN总线获取的车联网信息。
例如，通信单元102还被配置为经由如下中的一种或多种方式从车用辅助采集器获取所采集的与车辆有关的信息：PC5接口，车内WiFi，蓝牙连接。这里所述的车用辅助采集器用于辅助采集车辆相关信息，例如为车载诊断***(On Board Diagnostics，OBD)、行车记录仪、车辆信息采集APP、各种车用传感器等等。这些车用辅助采集器并不具备4G、5G通用Uu接口的联网功能，因此可以通过PC5接口、车内WiFi或者蓝牙连接等与移动智能应用子***连接，以传递所采集到的车辆相关信息比如车辆自身行驶数据、部分环境数据等。
图3示出了移动智能应用子***和车用辅助采集器的硬件连接***架构的示意图。其中，示出了Ⅱ型车载诊断***(OBD II)作为车用辅 助采集器的示例。移动智能应用子***例如通过本实施例的通信单元102将车辆状态消息上传到企业/个人云平台，进而传递到公共云平台。
在一个示例中，移动智能应用子***和车用辅助采集器独立执行与车辆有关的信息的采集。在另一个示例中，车用辅助采集器可以在移动智能应用子***的控制下执行与车辆有关的信息的采集，例如，由移动智能应用子***向车用辅助采集器发送执行数据采集的指令或者指定数据采集的周期和定时等。
然而，可能存在移动智能应用子***的信息采集频率和车用辅助采集器的信息采集频率不一致的情形。在这种情况下，通信单元102可以被配置为分开发送通过移动智能应用子***采集的与车辆有关的信息和通过车用辅助采集器采集的与车辆有关的信息。例如，可以在图3中所示的企业/个人云平台或公共云平台处对两类信息进行融合，以获得对于车辆状态的全面认知。
此外，可以在移动智能应用子***处对上述两类信息进行融合，从而以统一的发送周期进行发送。具体地，生成单元101被配置为通过对通过移动智能应用子***采集的数据与通过车用辅助采集器采集的数据进行融合来生成车辆状态消息。
例如，在不同的数据项的采集频率不同的情况下，生成单元101和通信单元102被配置为以其中较高的频率生成和发送车辆状态消息。示例性地，车辆历史轨迹和路线预测字段相关的数据的更新频率(采集频率)高，而车门后备箱状态以及充电状态字段相关的数据的更新频率低，则生成单元101按照车辆历史轨迹和路线预测字段相关的数据的更新频率来生成车辆状态消息，相应地，通信单元102以同样的频率发送车辆状态消息。
其中，在采集频率低的数据项没有更新的发送周期中，生成单元101被配置为将在该发送周期中发送的车辆状态消息中与采集频率低的数据项对应的字段设置为空或者将该字段设置为无效字段。例如，在上述示例中，车门后备箱状态以及充电状态字段可以定期地缺失。
在上述情况下，移动智能应用子***可以具有三个功能单元：感知单元、计算单元和通信单元，如图4所示。其中，感知单元执行与车辆有关的信息的采集的功能，计算单元执行两类信息的融合以及车辆状态 消息的生成功能，通信单元执行与其他子***或设备的通信，这里所述的通信单元例如由本实施例的通信单元102实现。
如前所述，通信单元102将所生成的车辆状态消息发送至中央子***，例如图3中所示的云平台，以使得中央子***根据所收到的车辆状态消息进行车辆通知、调度等车路协同操作。
此外，在发生紧急事件的情况下，通信单元102还可以将车辆状态消息通过局部广播发送至RSU。RSU还可以将采集到的环境和道路异常信息发送给通信单元102。例如，可以通过图2中所示的接口A15来实现通信单元102与RSU之间的信息交互。这样，可以省去上云再下发的过程，降低时延，能够尽快地实现紧急状态预警。另外，在这种情况下，车辆状态消息还可以由RSU上传至中心子***。例如，中心子***可以相应地更新已有数据。
为了便于理解，下面参照图5给出电子设备100的一个应用场景的示例。图5示出了主车(Host Vehicle，HV)超车主动预警的示意图。在图5的场景中，例如，HV上安装有或放置有根据本实施例的电子设备100，电子设备100基于移动智能应用子***和车用辅助采集器采集的与车辆有关的信息生成车辆状态消息，其中包括例如车辆速度和车头朝向的信息。在HV例如在十字路口或道路较窄的通道上时，可以进入弱势交通参与者碰撞预警模式，即，电子设备100通过V2N2P的方式将车辆状态消息提供给弱势交通参与者比如行人、自行车、电动自行车等，以提醒其小心后方或左转车辆接近。其中，V2N2P的方式指的是电子设备100将车辆状态消息发送至中心子***，然后由中心子***下发至个人。
例如，在HV是特殊车辆比如救护车时，可以进入紧急车辆让行预警模式，即，电子设备100将HV的车辆状态消息比如包括车辆属性和路线预测广播至RSU，以实现最大程度的提前避让。
应该理解，以上仅给出了电子设备100的应用场景示例，并不是限制性的。
综上所述，根据本实施例的电子设备100通过利用4G或5G通用网络接口来发送由车载移动智能子***和/或车用辅助采集器采集的车辆状态信息，方便地实现了车路协同应用。
<第二实施例>
在上文的实施方式中描述用于无线通信的电子设备的过程中，显然还公开了一些处理或方法。下文中，在不重复上文中已经讨论的一些细节的情况下给出这些方法的概要，但是应当注意，虽然这些方法在描述用于无线通信的电子设备的过程中公开，但是这些方法不一定采用所描述的那些部件或不一定由那些部件执行。例如，用于无线通信的电子设备的实施方式可以部分地或完全地使用硬件和/或固件来实现，而下面讨论的用于无线通信的方法可以完全由计算机可执行的程序来实现，尽管这些方法也可以采用用于无线通信的电子设备的硬件和/或固件。
图6示出了根据本申请的一个实施例的用于无线通信的方法的流程图，该方法包括：基于通过移动智能应用子***和/或车用辅助采集器采集的与车辆有关的信息生成车辆状态消息(S11)；以及通过4G移动通信网络或5G移动通信网络将车辆状态消息发送至中心子***和/或路侧单元(S12)。该方法例如可以在UE侧执行。
例如，车辆状态消息可以包括车辆基本安全消息和车辆扩展安全消息。车辆基本安全消息例如包括如下中的一个或多个：车辆的速度，车辆的地理位置，车辆的三轴加速度信息，车辆位置的置信度，车牌信息，车辆类型，车头朝向，时间戳。车辆扩展安全消息例如包括如下中的一个或多个：车辆特殊事件状态，车辆历史轨迹，路线预测，车身灯光状态，车门后备箱状态，车辆自身的行驶数据。
例如，步骤S11包括：对通过移动智能应用子***采集的数据与通过车用辅助采集器采集的数据进行融合来生成车辆状态消息。在不同的数据项的采集频率不同的情况下，可以以较高的频率生成和发送车辆状态消息。
例如，在采集频率低的数据项没有更新的发送周期中，将在该发送周期中发送的车辆状态消息中与采集频率低的数据项对应的字段设置为空或者将该字段设置为无效字段。
移动智能应用子***可以包括如下之一：智能手机、智能后视镜、智能行车记录仪。可以经由如下中的一种或多种方式从车用辅助采集器获取所采集的与车辆有关的信息：PC5接口，车内WiFi，蓝牙连接。
此外，在发生紧急事件的情况下，可以将车辆状态消息通过局部广 播发送至RSU。该车辆状态消息可以由RSU上传至中心子***。
注意，上述方法的细节在第一实施例中已经进行了详细描述，在此不再重复。
本公开内容的技术能够应用于各种产品。如前所述，电子设备100可以被实现为各种用户设备。
