具体实施方式
附图的详细说明意在作为本申请的当前一些实施例的说明，而非意在代表本申请能够得以实现的仅有形式。应理解的是，相同或等同的功能可以由意在包含于本申请范围之内的不同实施例完成。
参阅图1，本申请的一个实施例提供一种汽车上下电控制方法，包括以下步骤：
步骤S1、通过预设的SOA服务接口接收配电服务调用参数；其中，所述配电服务调用参数包括至少一个配电单元参数，所述配电单元参数包括诊断地址和配电端口状态，所述诊断地址与配电端口对应，所述配电端口状态包括闭合端口、断开端口。
具体而言，本实施例应用汽车端，汽车端基于SOA向服务消费者提供智能配电服务，服务消费方为外部应用终端，通过所述预设的SOA服务接口接收配电服务调用参数，图2为所述配电服务调用参数的生成流程，外部应用终端在调用本实施例提供的智能配电服务时，外部应用 终端向云端发送基于SOME/IP协议的配电指令，所述云端将所述配电指令下发至汽车端的T-Box，所述T-Box将基于SOME/IP协议的配电指令进行协议转换得到对应的配电服务调用参数；在此过程中，外部应用终端为客户端，云端为服务器，服务器能够服务于多个客户端和汽车端，将多个客户端的配电指令发送给对应的汽车端的T-Box，实现应用终端远程操作汽车端的ECU上下电控制。
其中，外部应用终端例如是OTA-VSM、远程控制、付费引擎等，OTA-VSM、远程控制、付费引擎为不同的应用终端的远程操作；OTA-VSM指的是汽车各控制器通过OTA进行软件升级；远程控制指的是类似远程解锁/启动、远程开启空调等等一些操作，付费引擎指的是通过手机APP等订阅一些个性化服务。
其中，所述配电服务调用参数可以包括一个或多个配电单元参数，一个配电单元参数对应一个配电端口，所述配电单元参数是一个数据结构体，如图3所示的例子，配电服务调用参数包括三个配电单元参数，每个配电单元参数都包括诊断地址和配电端口状态的参数；配电端口闭合为上电，配电端口断开为下电。
步骤S2、对所述配电单元参数进行仲裁确定是否对与所述诊断地址对应的配电端口进行配电，若确定对所述配电端口进行配电，则判断所述配电端口是否为常电端口；若是常电端口，则返回配电成功信号给服务消费方，若不是常电端口，则生成上电请求信号；其中，所述上电请求信号包括所述配电端口、所述配电端口状态。
具体而言，本实施例中分别对每一个配电单元参数进行仲裁，根据仲裁结果控制与配电单元参数对应的配电端口上电或下电。
其中，本实施例中预先为每一个配电端口设置一个与其匹配的诊断地址，并通过表格的形式保存配电端口和诊断地址之间的映射关系；本实施例定义了外部应用终端调用汽车的智能配电服务后控制各ECU上下电的逻辑，基于预设的仲裁逻辑对接收到的配电单元参数进行仲裁判定是否对与所述诊断地址对应的配电端口进行配电。
其中，本实施例还对配电端口的类型进行区分，配电端口的类型包括常电端口和非常电端口，常电端口指的是端口常闭的类型，非常电端口指的是端口常开的类型。因此，在进行配电时，对于常电端口，并不需要进行端口控制，只需要通过T-Box和云端反馈配电成功信号给服务消费方，所述服务消费方指的是上述的外部应用终端；对于非常电端口，则需要进行端口控制，因此，生成上电请求信号。
步骤S3、根据所述上电请求信号控制所述配电端口闭合。
需说明的是，当前OTA-VSM、远程控制、付费引擎等应用终端实现功能需求的过程中，是通过基于CAN信号的通信控制配电端口上下电，而本实施例基于SOA服务预设了统一的智能配电服务调用接口，允许服务消费者采用SOME/IP的方式通知/获取/更改智能配电系统配电端口状态，并定义了应用终端调用智能配电服务后的控制各ECU上下电的逻辑，降低软件的复杂性、减少软件开发周期及成本，同时，减少了整车的CAN信号交互，降低CAN总线的负载率，提升信号传输的稳定性。
进一步地，基于SOA服务设计原则，原子服务需要包括安全仲裁，组合服务需要包括场景 /车辆模式仲裁，需要设计服务的防火墙，用于管理暴露给不同服务消费方的接口调用权限，因此本实施例的智能配电服务调用接口具有半开放性，在满足整车功能安全的前提下，才可将服务接口调用权限暴露给服务消费方。
在一些实施例中，所述步骤S2，对所述配电单元参数进行仲裁确定是否对与所述诊断地址对应的配电端口进行配电，包括：
判断所述诊断地址是否合法；若不合法，则返回配电无效信号给服务消费方，若合法，则获取与所述诊断地址对应的配电端口，判断所述配电端口是否故障；若故障，则返回端口故障信号给所述服务消费方，若无故障，则确定对所述配电端口进行配电。
具体而言，本实施例的仲裁逻辑为：预先为每一个配电端口设置一个与其匹配的诊断地址，并通过表格的形式保存配电端口和诊断地址之间的映射关系，通过查询所述表格，判断接收到的诊断地址是否在所述表格中，若在所述表格中，则诊断地址为合法，若在所述表格中，则诊断地址为不合法。若诊断地址是合法的，则根据所述表格获取与诊断地址对应的配电端口，判断该配电端口是否故障，如果故障则无法进行配电，如果正常则可以进行配电。
其中，所述配电无效信号和端口故障信号都是通过T-Box和云端反馈配电成功信号给服务消费方，T-Box为是汽车端与云端进行数据传输的无线通信模块，与云端基于SOME/IP协议进行通信。
在一些实施例中，所述配电单元参数还包括配电时长，所述上电请求信号还包括所述配电时长。
具体而言，每个配电单元参数都包括配电时长，所述配电时长指的是服务消费方对汽车进行远程操作时对应的配电端口需要配电的最大时长，配电时长需满足远程操作的耗时需求，也即，如果配电时长太短，则无法完成远程操作。每个配电端口的配电时长是预先设定的，也即诊断地址、配电时长、配电端口是一一对应的。
所述方法还包括：
步骤S4、在控制所述配电端口闭合的同时开始计时。
步骤S5、当计时结果达到所述配电时长时，若没有接收到与所述诊断地址对应的新的配电单元参数，则控制所述配电端口断开，并返回配电停止信号给所述服务消费方。
具体而言，本实施例提出了配电计时关断的方案，在配电时间达到所述配电时长后，如果没有新的配电需求，则自动停止配电，减少不必要的耗电，能够防止远程操作异常，或长时间配电导致汽车的低压蓄电池馈电。所述配电停止信号通过T-Box和云端反馈配电成功信号给服务消费方。
在一些实施例中，所述方法还包括：
步骤S6、当计时结果未达到所述配电时长时，若接收到与所述诊断地址对应的新的配电单元参数，且新的配电单元参数的配电端口状态为闭合端口，则清零计时结果，并重新开始计时。
具体而言，所述新的配电单元参数包括诊断地址、配电端口状态、配电时长，每次接收到新的配电单元参数且新的配电单元参数的配电端口状态为闭合端口，则需要重新计时，以满足新的远程操作的耗时需求。
在一些实施例中，所述方法还包括：
步骤S7、当计时结果未达到所述配电时长时，若接收到与所述诊断地址对应的新的配电单元参数，且新的配电单元参数的配电端口状态为断开端口，则生成下电请求信号；其中，所述下电请求信号包括所述配电端口、新的配电单元参数的配电端口状态。
步骤S8、根据所述下电请求信号控制所述配电端口断开，并返回配电停止信号给所述服务消费方。
具体而言，新的配电单元参数同样包括诊断地址、配电端口状态、配电时长，其中，如果新的配电单元参数的配电端口状态为闭合端口，则配电时长可以是默认的无效值，例如是0；如果接收到与所述诊断地址对应的新的配电单元参数，且新的配电单元参数的配电端口状态为断开端口，则服务消费方请求断开配电端口，远程操作结束，此时生成下电请求信号。所述配电停止信号通过T-Box和云端反馈配电成功信号给服务消费方。
基于以上实施例的内容可知，本实施例的方法能够方便智能配电软件敏捷开发，节省开发成本，满足服务消费方、车辆控制系统的再次开发，功能扩展性更强；还能够满足不同应用场景下的上下电服务调用，实现一对一功能上下电，灵活性强。
与上述实施例的一种汽车上下电控制方法对应，本申请的另一个实施例还提供一种汽车上下电控制系统，参阅图4，本实施例的系统包括：
