下面结合附图，对本申请实施例作进一步阐述。
如图1所示，图1是本申请一个实施例提供的用于执行车辆热失控处理方法的系统架构平台的示意图。
在图1的示例中，该系统架构平台包括车辆热失控处理装置100、BMS200、检测装置300、IHU(Infotainment Head Unit，信息娱乐主机)400、BCM(Body Control Module，车身控制器)500、第一终端600、第二终端700和云服务器800，其中，上述的车辆热失控处理装置100、BMS200、检测装置300、IHU400和BCM500之间可以通过CAN(Controller Area Network，控制器局域网络)总线进行连接，其次，车辆热失控处理装置100可以通过无线通信方式连接至第一终端600、第二终端700和云服务器800。另外，车辆热失控处理装置100设置有处理器110和存储器120，其中，处理器110和存储器120可以通过总线或者其他方式连接，图1中以通过总线连接为例。
需要说明的是，关于上述图1中的车辆热失控处理装置100，具体结构参照图2所示，车辆热失控处理装置100包括但不限于有MCU(Micro Control Unit，微控制单元)130、V2X(Vehicle to X，车联万物)通信模块140、定位模块150和Modem(调制解调器)160。其中，MCU130可以包括有上述图1中的处理器110和存储器120，此外，MCU130还可以包括有CAN收发器131，CAN收发器131可以从CAN总线上获取BMS200发出的热失控报警信息；V2X通信模块140被设置成与其他人、车进行短程无障碍通信；定位模块150被设置成获取车辆当前所处位置的精确信息；Modem160被设置成与云服务器800进行通信。
其次，对于图1中各种模块设备，BMS200主要作用是为了智能化管理及维护各个电池单元,监控电池的状态，实时有效地检测出电池的热失控事件，并及时有效地发出携带有风险等级的热失控报警信息；检测装置300可以为安装在车辆上的各种传感器或者摄像头；IHU400主要用于向车内人员推送文字消息或者发出声音；BCM500主要用于对车辆上的用电设备进行控制；第一终端600为车主所携带的终端设备；第二终端700为车辆周围一定范围内的终端设备。

基于上述系统架构平台，下面提出本申请的车辆热失控处理方法的各个实施例。
如图4所示，图4是本申请一个实施例提供的车辆热失控处理方法的流程图，该方法包括但不限于有步骤S100、步骤S200和步骤S300。
步骤S100，获取来自BMS的热失控报警信息；
步骤S200，根据热失控报警信息确定电池的风险等级，其中，风险等级表征电池温度对电池的影响程度；
步骤S300，根据风险等级执行与风险等级对应的预设处理。
在一实施例中，车辆上的BMS会实时监控电池的工作状态，当电池即将发生热失控事件或者已经发生热失控事件时，BMS会生成热失控报警信息，并将热失控报警信息通过CAN总线发送至车辆热失控处理装置，因此，车辆热失控处理装置接收到热失控报警信息之后能够根据热失控报警信息确定电池当前的风险等级，并根据电池当前的风险等级执行对应的预设处理，以提高车辆的安全性能。
可以理解的是，关于上述的车辆热失控处理装置，可以为TBOX(Telematics BOX，车载远程信息处理器)。
需要说明的是，关于上述的预设处理，可以是推送文字消息、发出报警声音、调节电池的工作状态、调节车速或者开启车门锁等等处理。
值得注意的是，关于上述的风险等级，主要用于表征电池温度对电池的影响程度，可以包括有多个等级，示例性地，本申请实施例将风险等级按照严重程度划分为三个等级，分别为第一风险等级、第二风险等级和第三风险等级。其中，第一风险等级表征电池当前的温度接近设定门限,设定门限为电池温度继续升高会造成电池损害的临界；第二风险等级表征电池当前可以通过加大散热效率或者降低输出功率等而使得电池温度降低；第三风险等级表征电池当前处于即使加大散热效率和降低输出功率也仍然无法使得电池温度得以控制的状态。其中，第一风险等级、第二风险等级和第三风险等级所表征的影响程度依次增大。
具体地，基于上述的三个风险等级，下面提出本申请关于不同风险等级的车辆热失控处理方法的各个实施例。
如图5所示，图5是本申请一个实施例提供的在第一风险等级下的车辆热失控处理方法的流程图。在一实施例中，关于上述的步骤S300中的根据风险等级执行与风险等级对应的预设处理，包括但不限于有步骤S400。
步骤S400，当风险等级为第一风险等级，根据热失控报警信息生成第二警报信息，并发送第二警报信息至第一终端，以使第一终端向车主推送第二警报信息。
在一实施例中，当车辆上的BMS监测到电池的热失控状态处于第一风险等级时，BMS会生成带有第一风险等级的热失控报警信息，并将热失控报警信息通过CAN总线发送至车辆热失控处理装置，车辆热失控处理装置接收到热失控报警信息之后能够根据热失控报警信息确定电池当前的风险等级处于第一风险等级，同时车辆热失控处理装置会通过检测装置获取车内的人员乘载情况，当检测到车内无人时，车辆热失控处理装置会发送第二警报信息至第一终端，其中，上述的第一终端为车主所携带的终端设备。因此，本申请实施例能够在电池的风险等级为第一风险等级的情况下将电池状态告知车主，便于提醒车主及时降低电池的输出功率并检修发热原因，从而能够提高车辆的安全性能。
需要说明的是，当BMS将热失控报警信息通过CAN总线发送至车辆热失控处理装置的时候，若CAN网络已休眠，需要先唤醒CAN网络，才可以顺利将热失控报警信息通过CAN总线发送至车辆热失控处理装置。
可以理解的是，当车辆热失控处理装置根据热失控报警信息确定当前电池的风险等级处于第一风险等级之后，若检测到车内有人时，车辆热失控处理装置可以向汽车主机IHU推送第一风险等级的文字提示，示例性地，上述的文字提示可以为“当前动力电池过热，可能电池内部电路有问题，请及时进行检修”；同时，车辆热失控处理装置还可以向汽车主机IHU发出对应的报警声，从而告知车内的人员，便于提醒车主及时降低电池的输出功率并检修发热原因，从而能够提高车辆的安全性能。
另外，关于上述用于检测车内人员乘载情况的检测装置，可以为摄像头、座椅压力传感器或者座椅红外传感器等等。
值得注意的是，关于上述的第一风险等级，是指当前电池的温度接近设定门限,设定门限为电池温度继续升高会造成电池损害的临界；当电池的温度继续升高时会对电池造成损害，因此，本申请实施例能够在第一风险等级的情况下及时告知车主降低电池的输出功率并检修发热原因。
如图6所示，图6是本申请另一个实施例提供的在第一风险等级下的车辆热失控处理方法的流程图。在一实施例中，在执行上述步骤S400之后，该车辆热失控处理方法还包括但不限于有步骤S500。
步骤S500，当在预设时间段内没有获取到来自第一终端的基于第二警报信息的确认信息，间隔预设时间段将第二警报信息发送至第一终端，直至第二警报信息的发送次数大于预设次数，或者直至获取到确认信息。
在一实施例中，当车辆热失控处理装置将第二警报信息发送至车主所携带的第一终端之后，车辆热失控处理装置会启动第一预设周期为T1的计时,检测是否收到车主的确认信息,如果车辆热失控处理装置接收到车主所反馈的确认信息，则完成并结束报警流程；如果车辆热失控处理装置没有接收到车主所反馈的确认信息，在第一预设周期T1时间后再次向车主发送第二警报信息并记录发送次数C1，当发送次数C1达到预设次数N后仍没有收到车主所反馈的确认信息时，那么车辆热失控处理装置则会将本次的电池热失控事件上报至云服务器，并结束报警流程。因此，本申请实施例能够将第二警报信息多次发送至车主所携带的第一终端，能够提高第一终端成功接收第二警报信息的概率。
基于上述在第一风险等级下的车辆热失控处理方法，本申请另一个实施例提供了一种在第一风险等级下的具体的车辆热失控处理方法，如图7所示的流程图，该车辆热失控处 理方法还包括但不限于有步骤S601、步骤S602、步骤C101、步骤S603、步骤S604、步骤C102、步骤S605和步骤S606。
步骤S601，BMS检测到电池发生热失控事件；
步骤S602，BMS将热失控报警信息通过CAN总线发送至车辆热失控处理装置；
步骤C101，车辆热失控处理装置收到热失控报警信息后检测车内是否有人，如果无人，进入步骤S603；如果车内有人，进入步骤S604；
步骤S603，车辆热失控处理装置向车主所携带的第一终端发送第二警报信息,然后进入步骤C102；
步骤S604，车辆热失控处理装置向汽车主机IHU推送第一风险等级的文字提示并发出报警声，然后进入步骤S606；
步骤C102：车辆热失控处理装置启动第一预设周期为T1的计时,检测是否收到车主的确认信息,如果收到车主的确认信息，则进入步骤S606；如果没有收到车主的确认信息,T1时间后再次向车主发送第二警报信息并记录发送次数C1；发送N次后仍没有收到车主的确认信息，则进入步骤S605；
步骤S605，车辆热失控处理装置将热失控事件上报至云服务器；
步骤S606，结束。
值得注意的是，本申请实施例的车辆热失控处理方法的具体实施方式及对应的技术效果，可对应参照上述车辆热失控处理方法的实施例。
如图8所示，图8是本申请一个实施例提供的在第二风险等级下的车辆热失控处理方法的流程图。在一实施例中，关于上述的步骤S300中的根据风险等级执行与风险等级对应的预设处理，包括但不限于有步骤S700。
步骤S700，当风险等级为第二风险等级，根据电池的工作状态发送第一控制指令至BMS，以使BMS根据第一控制指令执行预设控制操作。
在一实施例中，当车辆上的BMS监测到电池的热失控状态由第一风险等级上升为第二风险等级时，BMS会生成带有第二风险等级的热失控报警信息，并将热失控报警信息通过CAN总线发送至车辆热失控处理装置，车辆热失控处理装置接收到热失控报警信息之后能够根据热失控报警信息确定电池当前的风险等级处于第二风险等级，由于第二风险等级表征当前电池处于可以在预设控制操作下能够使得电池温度降低的阶段，因此，车辆热失控处理装置会发送第一控制指令至BMS，然后BMS会根据第一控制指令执行预设控制操作，从而使得电池的温度得以降低。因此，本申请实施例能够在电池的风险等级为第二风险等级的情况下自动控制BMS执行预设控制操作，使得电池的温度得以降低，避免电池的温度继续升高，从而能够提高车辆的安全性能。
可以理解的是，当BMS将热失控报警信息通过CAN总线发送至车辆热失控处理装置的时候，若CAN网络已休眠，需要先唤醒CAN网络，才可以顺利将热失控报警信息通过CAN总线发送至车辆热失控处理装置。
需要说明的是，当车辆热失控处理装置接收到热失控报警信息之后并且根据热失控报警信息确定当前电池的风险等级处于第二风险等级之后，车辆热失控处理装置还会通过检测装置获取车内的人员乘载情况，当检测到车内无人时，车辆热失控处理装置会发送告警信息至第一终端，其中，上述的第一终端为车主所携带的终端设备。当检测到车内有人时， 车辆热失控处理装置可以向汽车主机IHU推送第二风险等级的文字提示，示例性地，上述的文字提示可以为“当前动力电池过高，电池内部已有问题，请尽快加大散热停止使用并进行检修”；同时，车辆热失控处理装置还可以向汽车主机IHU发出对应的报警声，从而告知车内的人员，便于提醒车主及时加大散热并停止使用以及进行检修，从而能够提高车辆的安全性能。
另外，关于上述用于检测车内人员乘载情况的检测装置，可以为摄像头、座椅压力传感器或者座椅红外传感器等等。

在一实施例中，当车辆热失控处理装置接收到热失控报警信息并且根据热失控报警信息确定电池当前的风险等级处于第二风险等级之后，车辆热失控处理装置会启动第二预设周期为T2的计时，检测电池的散热功率是否加大，如果电池在后一时刻的散热效率高于前一时刻的散热效率，那么车辆热失控处理装置不会发送第一控制指令；如果电池的散热效率保持不变或者后一时刻的散热效率小于前一时刻的散热效率，那么车辆热失控处理装置就会发送第一控制指令至BMS，使得BMS提高对电池的散热效率，使得电池的散热效率得以增强。因此，本申请实施例能够在电池的风险等级为第二风险等级的情况下强制控制BMS增大对电池的散热效率，使得电池的温度得以降低，从而能够提高车辆的安全性能。

在一实施例中，当车辆上的BMS监测到电池的热失控状态处于第三风险等级时，BMS会生成带有第三风险等级的热失控报警信息，并将热失控报警信息通过CAN总线发送至车辆热失控处理装置，车辆热失控处理装置接收到热失控报警信息之后能够根据热失控报警信息确定当前电池的风险等级处于第三风险等级，同时车辆热失控处理装置会通过检测装置获取车内的人员乘载情况，当检测到车内有人时，车辆热失控处理装置会发送文字提示至汽车主机IHU并且发出对应的报警声，示例性地，上述的文字提示可以为“当前动力电池已经热失控，请尽快采取消防措施”，提醒车内人员电池的故障状况。然后，车辆热失控处理装置会通过检测装置获取当前车辆的行驶速度，当行驶速度小于或等于预设速度的情况下，发送第二控制指令至BCM以使BCM开启车门锁，从而使得车内人员安全地逃离故障车辆。因此，本申请实施例能够在电池的风险等级为第三风险等级的情况下降低车速并且打开车门锁，使得车内人员安全撤离故障车辆，从而能够提高车辆的安全性能。
需要说明的是，当BMS将热失控报警信息通过CAN总线发送至车辆热失控处理装置的时候，若CAN网络已休眠，需要先唤醒CAN网络，才可以顺利将热失控报警信息通过CAN总线发送至车辆热失控处理装置。
