本申请实施例提供的电动汽车热管理系统故障处理方法适用于热管理系统中电子器件出现故障的情况，对于热管理系统中机械部件出现故障的情况，不为本申请实施例的关注重点。VCU可以区分热管理系统中出现的故障为机械故障还是电子故障。可选的，VCU可以基于故障上报通道对机械故障和电子故障进行区分。一般来说，机械故障通过控制器、传感器或者执行器上报。而电子故障一般由电子器件自身上报。

可选的，故障处理预案以热管理模块的维度存储在VCU中。其中，目标热管理模块是故障电子器件所属的热管理模块。在VCU确定目标热管理模块以后，在目标热管理模块对应的全部故障处理预案中选择候选故障处理预案。其中，候选故障处理预案是指目标热管理模块中与故障电子器件相关的故障处理预案。
VCU基于故障电子器件的故障信息可以在候选故障处理预案中确定目标故障处理预案。
VCU执行目标故障处理预案中记载的处理方案减弱故障电子器件对热管理系统的影响，最大限度减轻因热管理系统中电子器件故障造成的人身财产损失。
本申请实施例的技术方案，响应于热管理系统发送的故障处理请求确定故障电子器件，并确定所述故障电子器件的故障信息；其中，所述热管理系统包括至少两个热管理模块；所述热管理模块包括至少两个电子器件；在所述热管理系统中确定所述故障电子器件所属的热管理模块，并将该热管理模块作为目标热管理模块；基于所述故障电子器件的故障信息，在所述目标热管理模块的候选故障处理预案中确定目标故障处理预案，并基于所述目标故障处理预案处理所述故障处理请求，提供了一种系统性的电动汽车热管理系统故障处理方法，可以提高电动汽车热管理系统的可靠性，保证了行车安全，提高了用户体验。

实施例二
图2是根据实施例二提供的电动汽车热管理系统故障处理方法的流程图。本实施例在上述实施例的基础上进行说明，示例性的，对操作“基于所述故障电子器件的故障信息，在所述目标热管理模块的候选故障处理预案中确定目标故障处理预案”进行说明。
如图2所示，该方法包括以下步骤。
S210、响应于热管理系统发送的故障处理请求确定故障电子器件，并确定所述故障电子器件的故障信息。
其中，所述热管理系统包括至少两个热管理模块；所述热管理模块包括至少两个电子器件。
S220、在所述热管理系统中确定所述故障电子器件所属的热管理模块，并将该热管理模块作为目标热管理模块。
S230、根据所述故障电子器件的故障信息中故障类型，在所述候选故障处理预案中确定初选故障处理预案，并确定所述初选故障处理预案的预案等级。
如上所述，候选故障处理预案是指目标热管理模块中与故障电子器件相关的故障处理预案。
继续上例进行说明，在故障电子器件为水阀的情况下，水阀的故障类型包括关闭异常或者开启异常。故障电子器件的故障类型不同所对应的故障处理预案存在差异。
其中，初选故障处理预案是指与故障类型对应的候选故障处理预案。
根据故障电子器件的故障信息中的故障类型，在候选故障处理预案中选择与故障类型相对应的作为预选故障处理预案。基于故障类型对候选故障处理预案进行筛选，可以有效缩小目标故障处理预案的筛选范围，提高目标故障处理预案的确定效率。
预案等级用于衡量执行故障处理预案对热管理系统的影响，一般来说，执行故障处理预案对热管理系统的影响越大，预案等级越高。
继续以上例进行说明，在故障电子器件为空调热管理模块和电池热管理模块共用的水阀的情况下，为了避免电池水路的水温超过45℃，故障处理预案可以是：禁用空调加热功能，以保证空调水路的水温不升高，避免电池水路的水温升高导致电池过热损伤电池寿命。执行上述故障处理预案会导致热管理系统的空调加热功能失效。据此，确定该故障处理预案的预案等级。
每个候选故障处理预案存在对应的预案等级。初选故障处理预案在候选故障处理预案中产生。初选故障处理预案同样存在对应的预案等级。基于预案等级可以对初选故障处理预案进行筛选。
S240、基于所述预案等级和所述故障等级，在所述初选故障处理预案中确定目标故障处理预案，并基于所述目标故障处理预案处理所述故障处理请求。
其中，故障等级根据故障电子器件对热管理系统的影响程度确定；预案等级用于衡量执行故障处理预案对热管理系统的影响。可选的，故障等级和预案等级以相同标准进行评定。
基于预案等级和故障等级，在初选故障处理预案中确定目标故障处理预案。示例性的，以故障等级作为基准等级，选择预案等级低于故障等级的初选故障处理预案，基于预案等级对选择出的初选故障处理预案进行排序，从中选择出预案等级最低的作为目标故障处理预案，以此降低对热管理系统的影响程度，最大限度减轻人身财产损失。
示例性的，在故障电子器件为空调热管理模块和电池热管理模块共用的水阀，且故障电子器件的故障类型为关闭异常的情况下，可以将禁用空调加热功能作为目标故障处理预案。故障电子器件的故障等级高于目标故障处理预案的预案等级。
VCU基于目标故障处理预案处理故障处理请求，示例性的，VCU通过整车控制器给空调控制器发送禁止加热请求，空调控制器接收到禁止加热请求后，不响应驾驶室加热请求，直到水阀故障排除，再恢复空调加热功能。
本申请的技术方案，根据故障电子器件的故障类型，对候选故障处理预案进行筛选，得到初选故障处理预案，缩小了目标故障处理预案的选择范围，提高目标故障处理预案的确定效率。本申请还确定初选故障处理预案的预案等级，基于故障等级和预案等级，在初选故障处理预案中确定目标故障处理预案，最大限度地降低了热管理系统故障带来的人身财产损失，提高了热管理系统的稳定性。
在一个可选的实施例中，确定所述故障电子器件的故障信息，包括：基于所述故障处理请求，确定所述故障电子器件的故障类型；基于故障类型和故障影响之间的关联关系，确定所述故障电子器件的故障影响，其中，所述关联关系根据所述热管理模块中电子器件之间的连接关系确定；基于所述故障影响，确定所述故障电子器件的故障等级。
故障类型用于确定电子器件发生了哪种故障。示例性的，故障电子器件可以为水阀，水阀的故障类型可以是关闭异常或者开启异常。故障类型不同所产生的故障影响不同。故障影响是指故障电子器件对热管理系统的影响。
其中，故障类型和故障影响之间的关联关系，根据热管理模块中电子器件之间的连接关系确定。在热管理系统搭建完成以后，热管理系统中的热管理模块是确定的，热管理模块中电子器件之间的连接关系也是确定的。连接关系决定了电子器件在热管理模块中的功能作用，在电子器件已知的情况下，基于热管理模块中电子器件之间的连接关系，可以确定每个电子器件的故障影响。
故障等级根据故障电子器件对热管理系统的影响程度确定。一般来说，电子器件对热管理系统的影响程度越大，电子器件的故障等级越高。
示例性的，以空调热管理模块和电池热管理模块共用的水阀为例进行说明。该水阀设置为控制空调水路和电池水路之间的通断，示例性的，控制该水阀可以将电池水路和空调水路导通，通过空调正温度系数(Positive Temperature Coefficient，PTC)设备给电池加热，满足电池加热需求；以及，控制该水阀可以将电池水路和空调水路切断，阻止空调水路的水进入到电池水路，满足驾驶室温度调节需求。其中，PTC是一种半导体发热陶瓷，当外界温度降低，PTC的电阻值随之减小，发热量反而会相应增加。
之所以在调节驾驶室温度的过程中，通过水阀切断电池水路和空调水路是因为电池水温需要保持在45℃以下，而空调水温最高可达90℃。若空调水路和电池水路导通，很可能导致电池水温超过45℃，一旦电池水温超过45℃，则会导致电池过热，存在电池损坏风险。
因此，可以确定水阀的故障类型为开启异常，所对应的故障影响为电池加热失效；水阀的故障类型为关闭异常，所对应的故障影响为电池过度加热。对电池加热是为了在较冷的天气使电池仍然具备较为优秀的放电能力。也就是说，电池加热失效并不会使电池受损，不会影响电池寿命。而电池过度加热，会使电池受损，影响电池寿命甚至导致起火影响人身财产安全。相较而言，水阀关闭异常的故障等级要高于水阀开启异常的故障等级。
在一个可选的实施例中，热管理模块的候选故障处理预案通过如下方式构建：确定所述热管理系统中至少两个热管理模块之间的耦合关系；确定热管理模块中电子器件的连接关系，以及多个电子器件在所述热管理模块中作用功能；基于所述耦合关系、连接关系和作用功能，为多个电子器件构建候选故障处理预案；基于电子器件的候选故障处理预案，构建所述热管理模块的候选故障处理预案。
其中，热管理系统中至少两个热管理模块并不是完全相互独立的，热管理系统中热管理模块的功能作用之间存在耦合，可表现为，不同热管理模块存在共用的电子器件。例如，电池热管理模块与空调热管理模块共用整车控制器、水阀、风扇、温度传感器和空调控制器。确定热管理系统中至少两个热管理模块之间的耦合关系，实际是确定热管理模块之间的影响关系，确定一个热管理模块发生故障时，对热管理系统中的其他热管理模块的影响。
电子器件作为构成热管理模块的基本单元，电子器件发生故障将直接影响热管理模块，不同电子器件的作用功能不同对热管理模块的影响程度不同。基于耦合关系、连接关系和作用功能，为不同电子器件构建候选故障处理预案。
基于电子器件的候选故障处理预案，构建热管理模块的候选故障处理预案，示例性的，将电子器件的候选故障处理预案以热管理模块的维度进行存储，将候选故障处理预案关联到电子器件所属的热管理模块。
上述技术方案提供了一种故障处理预案的构建方法，基于耦合关系、连接关系和作用功能，为热管理系统中的电子器件构建候选故障处理预案，覆盖了热管理系统中可能出现的，关于电子器件的全部故障，为提高热管理系统的稳定性提供了技术支持。
