技术领域
本公开涉及网络管理技术领域，尤其涉及一种网络唤醒方法、装置、电子设备及车辆。
背景技术
随着车辆电气技术的发展，车辆中的控制器越来越多，控制器所需要的网络也越来越复杂，网络的持续运行会导致整车在通电后处于高功耗模式，进而在车辆静态放置时会导致车辆静态电流过大，而引起蓄电池亏电。
通常，车辆中的网络在满足休眠条件后进入休眠状态，从而使得车辆运行在低功耗模式。当车辆中出现唤醒信号时，唤醒处于休眠状态的网络，但是，由于唤醒信号中存在异常信号，这些信号会导致处于休眠状态网络的不必要唤醒，进而导致车辆的耗电量增加。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚明白，以下结合具体实施例，并参照附图，对本公开进一步详细说明。
如图1A所示，车辆的控制器可以采用分层架构的方式实现对车辆的控制，在分层架构中，控制器被自上而下分为ASW(Application Software Layer，应用层)、RTE(Runtime Environment，运行环境层)、BSW(Basic Software Layer，底层)和控制单元，其中，应用层位于运行环境层的上层，运行环境层位于底层的上层，底层位于控制单元的上层，控制器的软件包括应用层、运行环境层和底层，控制器的硬件包括控制单元。
为保证应用层、运行环境层、底层和控制单元的无关性，每一层只能使用下一层所提供的接口，并向上一层提供相应的接口。这样，通过控制器的分层架构实现了车辆控制器中软件和硬件的分离开发与验证。
为了实现控制器的低功耗运行，与控制器连接的网络满足预先设定的休眠条件时，控制器和网络会一起进入休眠状态；在控制器和网络处于休眠状态时，当控制器获取到唤醒信号，控制器和网络一起进入工作状态，其中，工作状态的耗电量大于休眠状态的耗电量。
具体的，相关技术中的网络唤醒方法是通过控制器中的底层和应用层一起从休眠状态进入唤醒工作状态实现的。当车辆中的网络处于休眠状态时，控制器可以通过与应用层和底层通信交互的唤醒组件监控车辆中的唤醒信号，当唤醒组件监控到车辆出现唤醒信号时，唤醒组件生成唤醒应用层和底层的唤醒指令，将应用层和底层从休眠状态中唤醒，然后应用层生成网络唤醒指令，并通过底层将网络唤醒指令发送到网络，使得网络从休眠状态进入到唤醒状态。
这样做带来的问题有：在控制器中的应用层和底层进入休眠状态的情况下，当控制器获取到唤醒信号，控制器和网络一起进入工作状态，但是，唤醒信号中存在控制器和网络不能处理的信号，对于这样的唤醒信号，控制器和网络一起从休眠状态进入工作状态，会导致控制器和网络的耗电量增加，以及减少控制器中电子器件的使用寿命。
因此，为了提高网络的唤醒效率并延长控制器电子器件的使用寿命，亟需一种能够对唤醒信号进行过滤的网络唤醒方式。
如图1B所示，本实施例的方法应用于控制器，控制器包括唤醒组件、底层和应用层，底层与网络通信连接，本实施例的方法包括：
步骤101，通过唤醒组件获取唤醒信号，并将唤醒信号发送到底层。
在该步骤中，唤醒信号指的是能够将底层从休眠状态唤醒的信号，本实施例优选的唤醒信号可以是一直处于工作状态的唤醒组件(该唤醒组件设置于底层)获取到的，能够将底层从休眠状态唤醒的信号。例如，控制器可以是车身域控制器，应用层可以是车身域控制器中的AUTOSAR(Automotive Open System Architecture，车辆开放系统架构)中的ASW，底层可以是车身域控制器中的AUTOSAR中的BSW，唤醒组件可以是设置于BSW的监测器(monitor)。唤醒信号可以是唤醒组件获取到的硬接线传输的Pin(引脚)信号生成的信号，也可以是唤醒组件获取到的通信网络传输的NM(Network Management，网络管理报文)报文生成的信号。
可以理解的是，当控制器处于休眠状态时，为了获取控制器的唤醒信号，有一部分控制单元会一直处于工作状态。
步骤102，通过底层将唤醒信号发送到应用层。
在该步骤中，底层与应用层之间通过满足通信协议的通信接口进行数据交互，该唤醒信号将底层唤醒之后，通过底层与应用层之间的通信接口，将唤醒信号发送给应用层，进而唤醒应用层。
底层指的是能够提供基础服务的软件，应用层指的是能够提供控制算法的软件，例如，应用层可以是车身域控制器中的AUTOSAR中的ASW，BSW可以通过BSW中接口模块将Pin信号和NM报文发送到ASW。这样，通过底层将唤醒信号发送到应用层，避免了利用底层完成唤醒信号的匹配，实现了唤醒信号的分步处理。
步骤103，利用应用层采用预先存储的唤醒规则对唤醒信号进行匹配，得到匹配结果。
在该步骤中，唤醒规则指的是能够对唤醒信号进行过滤的规则，匹配结果指的是根据唤醒规则对唤醒信号进行匹配得到的结果。例如，当唤醒信号为关于拉动门把手的NM报文时，该唤醒信号对应的唤醒规则可以是拉动门把手需要在存在车钥匙信号的情况下可以发送开门信号，则可以将拉动门把手的NM报文和是否存在车钥匙信号进行匹配。
步骤104，采用应用层根据匹配结果生成唤醒指令，并将唤醒指令发送到底层。
在该步骤中，唤醒指令指的是能够用于底层唤醒网络的指令，例如，唤醒 指令可以通过应用层中的唤醒函数进行生成。
步骤105，通过底层利用唤醒指令唤醒处于休眠状态的网络。
在该步骤中，网络指的是能够向底层提供通信功能的单元，例如，网络可以包括LIN(Local Interconnect Network，本地总线)网络和CAN(Controller Area Network,控制器局域网络)网络。
通过上述方案，通过底层将唤醒信号发送到应用层，避免了利用底层完成唤醒信号的匹配，实现了唤醒信号的分步处理；利用应用层根据唤醒规则对唤醒信号进行匹配，并根据匹配结果得到唤醒网络的唤醒指令，通过唤醒规则对唤醒信号进行过滤，阻止对不符合唤醒规则的唤醒信号进行唤醒指令的生成，减少了网络唤醒的次数，进而降低了整车的耗电量。
在一些实施例中，唤醒组件与状态单元连接；步骤101的步骤展开具体包括：
通过唤醒组件采用预先设置的周期向状态单元发送查询信号；
通过唤醒组件接收状态单元发送的根据查询信号得到的状态信号；
通过唤醒组件根据状态信号生成唤醒信号。
在上述方案中，状态单元指的是状态信号所在的单元，例如，状态信号可以是车辆中车身域控制器的MCU(Microcontroller Unit，微控制单元)集成电路中的Pin信号，也可以是CAN网络链路中的NM报文，状态单元可以是集成电路中的Pin脚，也可以是CAN网络链路。
具体的，当底层、应用层和网络处于休眠状态时，控制器中的唤醒组件一直处于工作状态，并且唤醒组件采用周期轮询的方式获取状态单元的状态信号，并根据状态信号确定唤醒信号。例如，SLP通过硬接线获取车身Pin信号，当Pin信号为高电平时，SLP生成唤醒信号并将该唤醒信号发送到底层。
通过上述方案，为后续生成唤醒信号提供数据基础。
在一些实施例中，状态信号至少包括下列之一：引脚电平和网络报文；
通过唤醒组件根据状态信号生成唤醒信号，包括：
响应于确定引脚电平不同于预先存储的电平信号或存在网络报文，通过唤醒组件根据预先存储的信号函数生成唤醒信号。
在上述方案中，引脚电平指的是通过硬接线获取的信号，网络报文指的是通过通信网络链路获取的信号，例如，当Pin信号为高电平时，与预先存储的低电平信号不同，则采用信号函数根据高电平信号生成对应的唤醒信号；当 CAN网络链路中存在NM报文时，则采用信号函数根据NM报文生成对应的唤醒信号。通过上述方案，为后续初始唤醒指令和唤醒指令的生成提供数据基础。
在一些实施例中，步骤102具体包括：
通过唤醒组件根据唤醒信号生成初始唤醒指令，其中，初始唤醒指令用于唤醒底层；
通过底层将唤醒信号发送到应用层。
在上述方案中，初始唤醒指令指的是能够唤醒底层的指令，例如，初始唤醒指令可以通过唤醒组件中的初始唤醒函数进行生成，在初始唤醒指令唤醒底层后，底层从休眠状态转为工作状态，工作状态下的底层可以通过底层和应用层的接口将唤醒信号发送到应用层。
通过上述方案，初始唤醒指令的生成实现了控制器中底层和应用层的分步唤醒，避免在获取到唤醒信号后底层和应用层由休眠状态进入工作状态。
在一些实施例中，如图1C所示步骤103具体包括：
步骤1031，利用应用层从唤醒规则中查找唤醒信号对应的匹配数据；
步骤1032，利用应用层获取唤醒信号对应的待匹配数据；
步骤1033，利用应用层对比待匹配数据和匹配数据，得到对比结果；
步骤1034，利用应用层根据对比结果生成匹配结果。
在上述方案中，匹配数据指的是唤醒规则中能够过滤唤醒信号的数据，例如，当唤醒信号为关于拉动门把手的NM报文时，该唤醒信号对应的唤醒规则可以是拉动门把手需要在存在车钥匙信号的情况下可以发送开门信号，匹配数据为需要存在车钥匙信号，待匹配数据为拉动门把手时存在车钥匙信号，当对比结果为拉动门把手时存在车钥匙信号时，匹配结果为拉动门把手的NM报文是匹配成功信号。
通过上述方案，通过唤醒规则对唤醒信号进行过滤，阻止对不符合唤醒规则的唤醒信号进行唤醒指令的生成，减少了网络唤醒的次数，进而降低了整车的耗电量。
在一些实施例中，步骤104具体包括：
响应于确定对比结果为待匹配数据与匹配数据相同，利用应用层将匹配结果中的唤醒信号设置为匹配成功信号；
响应于确定对比结果为待匹配数据与匹配数据不同，利用应用层将匹配结 果中的唤醒信号设置为匹配失败信号。
在上述方案中，匹配成功信号指的是符合唤醒规则的唤醒信号，匹配失败信号指的是不符合唤醒规则的唤醒信号，例如，当唤醒信号为关于拉动门把手的NM报文时，该唤醒信号对应的唤醒规则可以是拉动门把手需要在存在车钥匙信号的情况下可以发送开门信号，匹配数据为需要存在车钥匙信号，待匹配数据为拉动门把手时存在车钥匙信号，当对比结果为拉动门把手时存在车钥匙信号时，即待匹配数据与匹配数据相同，则匹配结果为拉动门把手的NM报文是匹配成功信号；当对比结果为拉动门把手时不存在车钥匙信号时，即待匹配数据与匹配数据不同，则匹配结果为拉动门把手的NM报文是匹配失败信号。
通过上述方案，根据唤醒规则对唤醒信号进行分类，得到匹配成功信号和匹配失败信号，为后续应用层对网络唤醒提供判断基础。
在一些实施例中，步骤105具体包括：
响应于确定匹配结果中的唤醒信号为匹配成功信号，利用应用层生成唤醒指令；
响应于确定匹配结果中的唤醒信号为匹配失败信号，利用应用层生成休眠指令并将休眠指令发送到底层，其中，休眠指令用于休眠底层。
在上述方案中，当唤醒信号为匹配成功信号时，表示该唤醒信号可以在与底层连接的网络中传输；当唤醒信号为匹配失败信号时，表示该唤醒信号不能在与底层连接的网络中传输。
具体的，当获取到唤醒信号时，应用层中的唤醒组件根据初始唤醒指令将底层唤醒，然后通过底层将唤醒信号传输到应用层，由应用层通过唤醒规则对唤醒信号进行判断，决定是否唤醒与底层连接的网络。由于应用层没有根据匹配失败信号生成网络的唤醒指令，避免了匹配失败信号对网络的唤醒，从而减少了网络的唤醒次数，进而降低了整车的耗电量。
通过上述方案，应用层根据匹配失败信号生成底层的休眠指令，避免了匹配失败信号对底层的持续唤醒，降低了底层的耗电量。
需要说明的是，本公开实施例的方法可以由单个设备执行，例如一台计算机或服务器等。本实施例的方法也可以应用于分布式场景下，由多台设备相互配合来完成。在这种分布式场景的情况下，这多台设备中的一台设备可以只执行本公开实施例的方法中的某一个或多个步骤，这多台设备相互之间会进行交互以完成的方法。

本公开的另一个具体实施例的网络唤醒方法，如图2所示，执行步骤包括：
步骤1，首先MCU(对应本公开实施例中的控制单元)会周期轮询硬线唤醒源PIN脚并监控CAN(Controller Area Network，控制器局域网)网络通道。
步骤2，如果PIN脚电平发生变化或者CAN网络通道有任何报文，首先域控制器唤醒底层，底层运行之后，底层唤醒应用层，底层把数据通过通信接口传递给应用层。
步骤3，应用层判断是否是合法唤醒源(对应本公开实施例中的匹配成功信号)，如果是合法唤醒源，则应用层给底层下发指令唤醒CAN和LIN(Local Interconnect Network，本地总线)网络；如果不是合法唤醒源，则给底层下发休眠指令，使底层继续睡眠。
