实施例二：
本实施例二公开了一种行车记录仪远程静默控制方法，所述控制方法基于上述实施例一所述的行车记录仪远程静默控制系统，所述行车记录仪远程静默控制方法是在出行公司云的请求下，主机厂云通过车载智能终端T-BOX唤醒包括车载多媒体主机HU和行车记录仪DVR在内的整车网络后，即进入睡眠状态，此后，行车记录仪DVR与车载多媒体主机HU之间通过wifi传输信号，车载多媒体主机HU与车载智能终端T-BOX之间通过USB传输信号，以实现执行本地任务，待本地任务执行完毕的情况下，车载多媒体主机HU通过USB通知车载智能终端T-BOX，并通过wifi通知行车记录仪DVR，进行协同的本地睡眠。
所述行车记录仪远程静默控制包括：远程调取行车记录仪存储数据、远程开启或关闭行车记录仪、远程设置行车记录仪参数、远程格式化行车记录仪存储数据以及远程备份行车记录仪存储数据。
以远程调取行车记录仪存储数据为例，所述行车记录仪远程静默控制过程具体如下：
S1：出行公司云向主机厂云发送唤醒请求；
S2：主机厂云通过TSP振铃方式远程唤醒车载智能终端T-BOX，并通过车载智能终端T-BOX唤醒包括车载多媒体主机HU以及行车记录仪DVR在内的整车CAN网络；
S3：车载多媒体主机HU被CAN网络唤醒后，开机初始化，并通过车载智能终端T-BOX与出行公司云建立连接，与此同时，行车记录仪DVR被CAN网络唤醒后，开机初始化，并与车载多媒体主机HU建立wifi连接；
S4：车载多媒体主机HU将其与行车记录仪DVR的连接状态发送至出行公司云，出行公司云在接收到行车记录仪DVR与车载多媒体主机HU连接建立成功的信号后，激活并下发远程调取指令给车载多媒体主机HU；
S5：车载多媒体主机HU向行车记录仪DVR发送“车载多媒体主机HU存储数据调取命令＝开始”；
S6：行车记录仪DVR向车载多媒体主机HU反馈“向行车记录仪DVR存储数据调取命令反馈信号＝开始”，此时，整车CAN网络进入睡眠状态，车载智能终端T-BOX、车载多媒体主机HU以及行车记录仪DVR保持本地唤醒状态。
S7：出行公司云下发调取参数至车载智能终端T-BOX，车载智能终端T-BOX通过USB将调取参数发送给车载多媒体主机HU，车载多媒体主机HU再通过wifi将调取参数发送给行车记录仪DVR；
S8：行车记录仪DVR通过wifi向车载多媒体主机HU传输存储数据文件，车载多媒体主机HU通过USB将存储数据文件传输至车载智能终端 T-BOX，并通过车载智能终端T-BOX将存储数据文件上传至出行公司云，直至存储数据文件传输完毕；
本步骤S8中，在行车记录仪DVR向外传输存储数据文件的过程中，还包括停止存储数据文件传输过程，所述停止存储数据文件传输过程包括主动停止传输过程和预设停止传输过程，其中：
所述主动停止传输过程如下：
A1：出行公司云向主机厂云发送唤醒请求；
A2：主机厂云通过TSP振铃方式远程唤醒车载智能终端T-BOX，并通过车载智能终端T-BOX唤醒整车CAN网络；
A3：车载多媒体主机HU向行车记录仪DVR发送“车载多媒体主机HU存储数据调取命令＝结束”；
A4：行车记录仪DVR向车载多媒体主机HU反馈“向行车记录仪DVR存储数据调取命令反馈信号＝结束”。
所述预设停止传输过程如下：
从车载多媒体主机HU开始调取行车记录仪DVR存储数据开始，当预设时间内，车载多媒体主机HU为接收到来自出行公司云的停止存储数据调取的命令式，车载多媒体主机HU主动控制行车记录仪DVR停止传输存储数据。
S9：存储数据文件传输完毕后，行车记录仪DVR通过wifi通知车载多媒体主机HU存储数据文件调取成功，任务结束；
S10：任务结束后，不再唤醒整车CAN网络，车载多媒体主机HU通过USB通知T-BOX，车载多媒体主机HU通过wifi通知行车记录仪DVR，车载智能终端T-BOX、车载多媒体主机HU以及行车记录仪DVR进行协同的本地睡眠。
需要注意的是：
1、所述车载智能终端T-BOX、车载多媒体主机HU以及行车记录仪DVR的睡眠/唤醒状态分别包括：整车CAN网络睡眠/唤醒和本地睡眠/唤醒两种；当整车CAN网络唤醒时本地一定唤醒，当本地睡眠时网络一定睡眠；但是，当整车CAN网络睡眠时本地不一定睡眠，当整车CAN网络可以先睡眠以便不影响整车睡眠，而本地可以保持唤醒状态继续执行未完成的本地任务。
2、当行车记录仪DVR开始执行控制指令任务后，车载智能终端T-BOX、车载多媒体主机HU以及行车记录仪DVR即可允许整车CAN网络进入睡眠状态，以便降低整车电流消耗。而在整车CAN网络处于睡眠的情况下，也不影响行车记录仪DVR通过wifi向车载多媒体主机HU传输数据，也不影响多媒体主机HU通过USB经车载智能终端T-BOX向出行公司云上传视频。
尽管上面已经示出和描述了本发明的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本发明的限制，本领域的普通技术人员在本发明的范围内可以对上述实施例进行变化、修改、替换和变型。
以上所述本发明的具体实施方式，并不构成对本发明保护范围的限定。任何根据本发明的技术构思所作出的各种其他相应的改变与变形，均应包含在本发明权利要求的保护范围内。
