具体实施例
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
针对本公开实施例背景技术中所提出的技术问题，本公开实施例提出了一种乘员舱和电池降温方法，可根据不同的驾驶阶段以及驾驶阶段中不同的情况自适应的改变对乘员舱降温和对电池降温的优先级策略，能体现“因时制宜”的思想原则，以使在有限的空调系统能力下，既能够满足电池的降温，不影响整车动力性和电池寿命；又能够满足乘员舱的降温舒适性，不引起客户抱怨；同时又能够最大程度的节省整车能耗，将更多的整车能量用于车辆续航，灵活性高。本公开实施例所提出的因时制宜的降温策略，给出整车空调系统的最大匹配性能边界，利于空调系统的成本控制。
参照图1，示出了本公开实施例一种乘员舱和电池降温方法的步骤流程图，所述方法具体可以包括以下步骤：
步骤S101，确定车辆当前的驾驶阶段；
针对整车使用的实际情况，本公开将驾驶阶段分为两个阶段，即启动阶段和运行阶段。
启动阶段指车辆刚上电时的阶段，此时用户可位于乘员舱内，也可不位于乘员舱内。上电指车辆的汽车点火档处于开启状态，即处于IG-ON模式。在IG-ON模式下仪表板上的灯亮，所有电器设备可以工作。
运行阶段指车辆启动后的驾驶过程，此时用户长时间位于乘员舱内。
示例的，车辆系统在接收到车辆上电启动的触发操作时，确定车辆当前处于所述启动阶段。
步骤S102，根据驾驶阶段与降温策略之间的对应关系，查询所述车辆当前的驾驶阶段对应的目标降温策略，其中，不同驾驶阶段对应不同降温策略，每个降温策略均包括对乘员舱降温和对电池降温；
考虑到夏季或车刚熄火下电又重新上电时，电池温度较高，本公开针对启动阶段，制定了电池优先的执行策略，以使得车辆电池在超过一定温度时能被及时降温，保证电池使用的温度需求。本公开各个实施例中的电池也可称为电池包，电池包可采用三元电芯，由模组串联组成，电池包内设有电池管理系统、电池热管理系统，可有效保护电池包安全。
考虑到在运行阶段，乘员舱内长时间有用户，此时制定了成员舱优先的执行策略，以满足乘员舱的降温性能，保证用户驾驶过程中的温度舒适性。
因此，本公开实施例的降温策略至少包括对应启动阶段的降温策略，以及对应运行阶段的降温策略。需要说明的是，在每个阶段的降温策略中，并不仅是单一满足对电池或乘员舱的降温，仍然需要考虑另一方的当前状态，即每个降温策略均包括对乘员舱降温和对电池降温。例如，在运行阶段的降温策略中，并不仅是单一的考虑仅对乘员舱降温，仍然需要考虑电池的当前状态，对电池进行降温。
驾驶阶段与降温策略之间的对应关系可作为执行程序存储在系统中，当系统在确定车辆当前的驾驶阶段后，可查询所存储的当前的驾驶阶段对应的目标降温策略，然后按照该目标降温策略，因时制宜地对乘员舱和电池中的至少一者进行降温。
步骤S103，按照所述目标降温策略，对乘员舱和/或电池降温。
具体而言，当车辆当前的驾驶阶段处于启动阶段时，步骤S103执行过程可以如下：
按照所述启动阶段对应的目标降温策略，优先仅对电池进行降温，直至电池当前的温度低至预设的电池第一温度阈值且乘员舱当前的温度超过预设的乘员舱第一温度阈值，切换为仅对乘员舱进行降温。
在本公开实施例中，本公开在启动阶段设定了电池第一温度阈值，当电池温度超过该温度阈值时，电池需要紧急降温，以保证电池的性能和维护其使用寿命。不同的电池有不同的性能，对应的标高温度不同，因此，所设定的电池第一温度阈值也可能不同。即，电池第一温度阈值的可参照汽车所实 际使用的电池进行设定，本公开不作限定。
在启动阶段，为体现电池优先降温的原则，从一方面，在本公开一实施例中，提供了以下步骤：
车辆上电启动后，系统优先对电池的温度进行检测，确定电池当前的温度，判断电池的当前温度是否超过电池第一温度阈值，当电池当前的温度超过所述电池第一温度阈值时，系统向空调系统发送指令，指示空调系统仅对电池进行降温，以优先满足电池在启动阶段的降温需求。
车辆上电启动后，若系统检测到电池的当前温度未超过(小于等于)电池第一温度阈值或者已经通过空调系统降低至小于电池第一温度阈值后，说明当前电池的降温需求不是最急切的，此时系统考虑乘员舱的降温需求。系统对乘员舱的温度进行检测，判断乘员舱当前的温度是否超过预设的乘员舱第一温度阈值，乘员舱第一温度阈值为乘员舱在启动阶段的标高温度值，在电池当前的温度低于电池第一温度阈值且乘员舱当前的温度超过乘员舱第一温度阈值时，系统向空调系统发送指令，以指示空调系统仅对乘员舱进行降温。但考虑到启动阶段，在仅对乘员舱降温的同时，电池由于持续放电，电池温度可能升高超过电池标高温度，因此，为体现电池优先降温的原则，从另一方面，在本公开一实施例中，还提供了以下步骤：
在仅对乘员舱进行降温的过程中，判断电池当前的温度是否超过预设的电池第二温度阈值，当电池当前的温度超过所述电池第二温度阈值时，切换为仅对电池进行降温；其中，所述电池第二温度阈值大于所述电池第一温度阈值。
换言之，本公开实施例在仅对乘员舱进行降温的过程中，时刻对电池当前的温度进行监测，以在电池温度过高时，及时切换为仅对电池进行降温。考虑到乘员舱降温时，由于电池放电或受外界环境影响会温升，如果仅将电池的当前温度与电池第一温度阈值进行比较，可能会造成系统切换频繁，影响空调系统性能的问题。因此，本公开还设置有电池第二温度阈值，电池第二温度阈值大于电池第一温度阈值，在此阶段中，系统将电池当前的温度与预先设置的电池第二温度阈值进行比较，并在电池当前的温度超过电池第二温度阈值时，切换为仅对电池进行降温，以此既可以优先满足电池在启动阶段的降温需求，也能避免对电池和对乘员舱进行降温切换过于频繁的问题。
综合考虑各因素，经过研究，电池第二温度阈值与电池第一温度阈值之间的差值可优选设置为2℃。如电池第一温度阈值为43℃，电池第二温度阈值为45℃。
由于本公开是针对空调系统的制冷双开工况而提出的，适应目前新能源汽车的发展，因此，就降温执行而言，本公开可采用水冷散热方式对电池进行降温。水冷散热系统主要包括：水泵、换热器、散热片、膨胀水箱等。水冷技术是基于液体热交换的冷却技术，比风冷技术效率更高，电动汽车电池组内部温度更均匀，可与车辆的冷却系统整合在一起，与电池壁面之间的热交换系数高，冷却、加热速度快。本公开对电池降温和对乘员舱降温的具体结构，不属于本公开的发明重点，本公开在此不做限定。
基于水冷降温方式，确定仅对电池进行降温时，系统向空调系统发送降温请求，降温请求中包括所请求的温度。由于不同的电池的标高温度不同，参考电池第一温度阈值，系统可预先设定与电池第一温度阈值对应的最佳降温请求温度，如当电池的温度超过43℃(电池第一温度阈值)时，系统向空调系统请求入口水温15℃。
针对启动阶段对应的目标降温策略，参照图2，示例的：
车辆上电后，判断电池当前的温度是否＞43℃；
若电池当前的温度＞43℃，则仅对电池进行降温，系统向空调系统请求电池请求入口水温为15℃；
若电池当前的温度≤43℃，系统判断乘员舱当前的温度是否≥33℃；
若乘员舱当前的温度≥33℃，则系统仅对所述乘员舱进行降温，开启空调，同时系统判断电池当前的温度是否＞45℃，并在＞45℃时，仅对电池进行降温，系统向空调系统请求电池请求入口水温为15℃。
上述对启动阶段对应的目标降温策略的执行方式进行了详细的介绍，接下来，本公开对运行阶段对应的目标降温策略的执行方式进行说明。
在本公开一实施例中，提供了车辆执行运行阶段对应的目标降温策略的两种情况：
情况一：当电池当前的温度未超过所述电池第一温度阈值且乘员舱当前的温度未超过所述乘员舱第一温度阈值时，按照所述运行阶段对应的目标降温策略，对乘员舱和/或电池降温。
此种情况的发生有两种可能，可能一是车辆上电启动后，系统检测到电池当前的温度未超过电池第一温度阈值且乘员舱当前的温度也未超过乘员舱第一温度阈值，那么相当于在启动阶段未对电池或乘员舱中任一者进行降温，系统直接进入运行阶段。可能二是车辆上电启动后，系统对电池进行了降温使得电池当前的温度未超过电池第一温度阈值，此时检测到乘员舱的温度也未超过乘员舱的标高温度(乘员舱第一温度阈值)，符合进入运行阶段的条件，系统开始执行运行阶段对应的目标降温策略。
参照图2，示例的，电池第一温度阈值为43℃，乘员舱第一温度阈值为33℃，当电池温度≤43℃且乘员舱温度≤33℃时，系统执行运行阶段对应的目标降温策略，以对乘员舱和/或电池降温。
情况二：在仅对乘员舱进行降温的过程中，当电池当前的温度未超过所述电池第二温度阈值且乘员舱当前的温度降低至小于等于预设的乘员舱第二温度阈值时，按照所述运行阶段对应的目标降温策略，对乘员舱和/或电池降温；
其中，所述乘员舱第二温度阈值小于所述乘员舱第一温度阈值。
此种情况的发生也有两种可能，可能一是车辆上电启动后，系统检测到电池当前的温度未超过电池第一温度阈值而乘员舱当前的温度超过了乘员舱第一温度阈值，对乘员舱进行了降温，使得乘员舱的温度降至小于等于预设的乘员舱第二温度阈值。可能二是系统在启动阶段对电池和乘员舱都依次进行了降温，最终在满足电池当前的温度未超过电池第二温度阈值的情况下，将乘员舱的温度降至小于等于预设的乘员舱第二温度阈值。此时，系统进入运行阶段，按运行阶段对应的目标降温策略，对乘员舱和/或电池降温。
需要说明的是，在情况二中，本公开将乘员舱温度与乘员舱第二温度阈值进行比较，而不与乘员舱第一温度阈值进行比较，一来也可避免系统切换频繁的问题，二来给予了系统充分时间判断电池是否超过预设的电池第二温度阈值，体现出在启动阶段优先仅对电池进行降温的策略，保证电池的降温需求，三来也使得运行阶段与启动阶段有明显的界限，使得避免系统执行策略混乱的问题。
参照图2，示例的，乘员舱第二温度阈值为30℃，在电池当前的温度≤45℃且乘员舱的温度≤30℃时，系统执行运行阶段对应的目标降温策略，以 对乘员舱和/或电池降温。
当车辆当前的驾驶阶段处于运行阶段时，步骤S103执行过程可以如下：
按照所述运行阶段对应的目标降温策略，优先对乘员舱进行降温，直至电池当前的温度超过预设的电池第三温度阈值，切换为仅对电池进行降温。
系统进入运行阶段后，执行乘员舱优先降温的原则，以优先保障成员舱的舒适性。但由于这一过程中，对于电动汽车而言，电池持续放电状态提供动力，电池温度会升高，因此，系统也会实时监测电池的当前温度，并在保持对乘员舱降温的同时，根据电池的温度情况对电池进行相应降温，除非电池当前的温度超过预设的电池第三温度阈值，才切换为仅对电池进行降温。这样在满足乘员舱优先降温的情况下，对电池的温度具有控制底线，避免电池温度升高至一定程度出现性能受影响，甚至爆炸的问题。
在本公开一实施例中，系统在对乘员舱进行降温的过程中，执行以下步骤：
判断电池当前的温度是否超过所述电池第三温度阈值；
在电池当前的温度未超过所述电池第三温度阈值时，根据电池温度与电池请求入口水温之间的对应关系，查询电池当前的温度对应的目标电池请求入口水温，并按照所述目标电池请求入口水温，对电池进行降温且同时保持乘员舱当前的温度不超过预设的乘员舱第三温度阈值，其中，电池不同的温度区间对应不同电池请求入口水温。
运行阶段，在保持对乘员舱降温的同时，根据电池的温度情况对电池进行相应降温，本公开根据研究，提供了对电池的逐级降温策略，预先设定了电池温度与电池请求入口水温之间的对应关系，电池不同的温度区间对应不同电池请求入口水温，这样既实现了对电池温度的控制，又能实现空调系统制冷双开工况的高效运转，有利于维护空调系统，避免其长时间处于高负荷状态。电池请求入口水温的逐级降低直至停止乘员舱降温，体现出了在车辆运行阶段中由乘员舱降温优先到电池降温优先的转变过程。
当然，基于运行阶段对乘员舱优先降温的策略，本公开也设定了在对电池进行逐渐降温时的温度下限，即对电池进行降温且同时需要保证乘员舱当前的温度不超过预设的乘员舱第三温度阈值。换言之，在电池温度未超过电池第三温度阈值而乘员舱当前的温度超过乘员舱第三温度阈值时，可仅对乘 员舱进行降温。
上述中，本公开实施例对电池第二温度阈值、电池第三温度阈值、乘员舱第一温度阈值、乘员舱第二温度阈值、乘员舱第三温度阈值均不作限定，保证降温策略实现的合理性即可。
在本公开实施例中，电池温度与电池请求入口水温之间的对应关系，包括：
当预设的电池第四温度阈值≤电池温度＜预设的电池第五温度阈值时，电池请求入口水温为温度一；
当所述电池第五温度阈值≤电池温度＜预设的电池第六温度阈值时，电池请求入口水温为温度二；
当所述电池第六温度阈值≤电池温度＜所述电池第三温度阈值时，电池请求入口水温为温度三；
其中，所述温度三＜所述温度二＜所述温度一。
上述中，电池第四温度阈值可设置为35℃，当电池温度低于电池第四温度阈值时，空调系统在运行阶段仅对乘员舱降温即可，可无需对电池进行降温。可选的，电池第五温度阈值可与电池第二温度阈值相同，如45℃，体现出启动阶段和运行阶段因时制宜的降温策略。本公开实施例对电池请求入口水温的温度值不做具体的要求，具体值可依据电池及电池包性能确定。
针对运行阶段对应的目标降温策略，参照图2，示例的：
在保持对乘员舱降温的同时，确定电池当前的温度，依据对电池的逐级降温策略，对电池进行降温，此过程中保证乘员舱的温度不超过28℃：
在35℃≤电池温度＜45℃时，电池请求入口水温为20℃；
在45℃≤电池温度＜50℃时，电池请求入口水温为15℃；
在50℃≤电池温度＜55℃时，电池请求入口水温为10℃；
当电池温度≥55℃时，将乘员舱空调断开，仅保留对电池的降温。

控制器304，用于执行如本公开实施例所述的乘员舱和电池降温方法，以控制所述空调系303统对乘员舱301和/或电池302降温。
本公开实施例的车辆，可根据不同的驾驶阶段以及驾驶阶段中不同的情况自适应的改变对乘员舱降温和对电池降温的优先级策略，能体现“因时制宜”的思想原则，以使在有限的空调系统能力下，既能够满足电池的降温，不影响整车动力性和电池寿命；又能够满足乘员舱的降温舒适性，不引起客户抱怨；同时又能够最大程度的节省整车能耗，将更多的整车能量用于车辆续航，灵活性高。
