在本实施例中，油门的开度信号即是油门节气门开度，其表征驾驶员的动力需求，油门节气门开度越大，相应地，动力需求越大。
在本实施例中，冷却液作为一种冷却介质，其在冷却管道中循环流动，带走驱动***中驱动电机和各控制器产生的热量，再通过与散热器进行热交换。
应该可以理解的是，油门节气门开度越大，动力需求越大，即驱动***中的驱动电机的功率越大。相应地，在所述车辆以该功率运行下，驱动***也越容易发生过热现象。考虑到油门开度信号可以反映驱动***是否会发生过热的特点，利用油门的当前开度信号和用于冷却驱动***的冷却液的当前温度，决定目标设备的运行参数，在驱动***发生过热之前，对驱动***进行冷却干预。
步骤S12：根据所述当前开度信号和所述当前温度，确定目标设备的运行参数。
在本实施例中，所述目标设备包括水泵和/或风扇，所述水泵用于调节所述冷却液的流量，所述风扇用于冷却所述驱动***。
步骤S13：根据所述运行参数，控制所述目标设备的运行状态，以对所述驱动***进行降温。
即通过控制水泵和/或风扇的运行状态来对驱动***进行降温，其中，水泵的运行参数例如可以是控制功率的占空比，风扇的运行参数例如可以是风扇转速。
采用上述技术方案，由于在车辆行驶中，油门开度信号的大小反映动力需求的大小，而动力需求的大小又于驱取决于驱动***中驱动电机的功率，且功率越大越容易产生热量，因此，油门开度信号能间接反映出驱动***是否会发生过热现象，本公开结合油门的开度信号和冷却液的温度，能在车辆驱动***发生过热之前，提前对车辆的驱动***进行冷却，避免了现有技术在驱动***在发生过热之后才对驱动***进行降温导致的驱动***存在过热风险的情况，有效地降低了车辆驱动***过热的风险。
为了使本领域技术人员能够更加清楚的理解本公开实施例提供的技术方案，下面对本公开实施例提供的用于车辆的冷却控制方法进行详细的说明。
在一种可能的实现方式中，电子设备预先设置有开度信号、温度与运行参数之间的关联关系，在此种情况下，上述步骤S12具体可以包括如图2所示的流程步骤，请参阅图2，上述步骤S12例如可以包括：
步骤S1211：根据所述当前开度信号，确定与该当前开度信号对应的目标油门开度等级。
在本实施例中，根据当前开度信号的大小，以及多个开度信号范围和油门开度等级之间的预设的关联关系，确定与当前开度信号匹配的目标开度信号范围，将该目标开度信号范围所对应的油门开度等级确定为目标油门开度等级。
步骤S1212：根据所述当前温度，确定与该当前温度对应的目标温度等级。
在本实施例中，根据当前温度的大小，与多个温度范围和温度等级之间的预设的关联关系，确定与当前温度匹配的目标温度范围，将该目标温度范围所对应的温度开度等级确定为目标温度等级。
步骤S1213：根据所述目标油门开度等级和所述目标温度等级，以及油门开度等级、温度等级与运行参数之间预设的关联关系，确定所述目标油门开度等级与所述目标温度等级所对应的运行参数。
在本实施例中，不同的目标油门开度等级和不同的目标温度等级对应不同的运行参数。示例地，以所述运行参数包括水泵占空比和风扇转速，请参阅图3，本公开提供一种油门开度与冷却液温度对应的目标设备的运行参数的示意图，该曲线示意图的横坐标为油门开度，纵坐标为冷却液的温度。具体的：
油门开度范围和油门等级的关联关系例如可以是：油门开度范围为0％至15％，对应的油门等级为1级；油门开度范围为15％至30％，对应的油门等级为2级，油门开度范围为30％至45％，对应的油门等级为3级，油门开度范围为45％至65％，对应的油门等级为4级，油门开度范围为65％至85％，对应的油门等级为5级，油门开度范围为85％至100％，对应的油门等级为6级。
温度范围和温度等级的关联关系例如可以是：温度范围为0℃至55℃，对应的温度等级为1级；温度范围为55℃至65℃，对应的温度等级为2级；温度范围为大于65℃，对应的温度等级为3级。
油门开度等级、温度等级与运行参数三者之间的预设的关联关系例如可以是：
当电子设备获取到的当前油门开度位于0％至15％之间，且当前温度在0℃至55℃的情况下，确定的运行参数包括水泵占空比为10％；
当电子设备获取到的当前油门开度位于15％至30％之间，且当前温度在0℃至55℃的情况下，确定的运行参数包括水泵占空比为20％；
当电子设备获取到的当前油门开度位于30％至45％之间，且当前温度在0℃至55℃的情况下，确定的运行参数包括水泵占空比为40％；
当电子设备获取到的当前油门开度位于45％至65％之间，且当前温度在0℃至55℃的情况下，确定的运行参数包括水泵占空比为60％；
当电子设备获取到的当前油门开度位于65％至85％之间，且当前温度在0℃至55℃的情况下，确定的运行参数包括水泵占空比为80％；
当电子设备获取到的当前油门开度位于85％至100％之间，且当前温度在0℃至55℃的情况下，确定的运行参数包括水泵占空比为80％；
当电子设备获取到的当前油门开度位于0％至85％之间，且当前温度在55℃至65℃的情况下，确定的运行参数包括水泵占空比为60％，以及风扇转速为第一转速；
当电子设备获取到的当前油门开度位于0％至85％之间，且当前温度在65℃以上的情况下，确定的运行参数包括水泵占空比为80％，以及风扇转速为第二转速。
当电子设备获取到的当前油门开度位于85％至100％之间，且当前温度在55℃以上的情况下，确定的运行参数包括水泵占空比为80％，以及风扇转速为第二转速。
需要说明的是，第一转速低于第二转速，在图3中，第一转速指低速，第二转速指高速。本实施例可根据实际需求设定第一转速和第二转速的值。
在上述示例中，在油门开度大和冷却液温度高时，可以只确定一种目标设备的运行参数即可满足对驱动***的快速降温的需求，以确保在满足对驱动***进行降温的条件下，最大程度上减少电力资源的消耗；而在油门开度过大和冷却液温度过高时，可以确定两种目标设备的运行参数，用以满足对驱动***的降温需求，在最大程度上降低驱动***过热的风险。
在另一种实施例中，考虑到所述驱动***其本身温度对确定运行参数的影响，具体的，请参阅图4，上述步骤S12例如可以包括：
步骤S1221：获取驱动***的当前温度。
步骤S1222：根据所述当前开度信号，确定与该当前开度信号对应的目标油门开度等级。
步骤S1222与图2中步骤S1211的类似，此处不再赘述。
步骤S1223：根据所述冷却液的当前温度，确定与该当前温度对应的目标温度等级。
步骤S1223与图2中步骤S1212的类似，此处不再赘述。
步骤S1224：根据所述驱动***的当前温度、所述目标油门开度等级和所述目标温度等级，以及驱动***温度、油门开度等级、温度等级与运行参数之间预设的关联关系，确定所述驱动***的当前温度、所述目标油门开度等级与所述目标温度等级所对应的运行参数。
在上述实施例中，通过考虑到驱动***其本身温度对确定运行参数的影响，建立驱动***温度、油门开度等级、温度等级与运行参数之间预设的关联关系，并根据所述驱动***的当前温度、所述目标油门开度等级和所述目标温度等级以及该关联关系确定运行参数，使确定的运行参数更合理化。
在本实施例中，根据所述水泵占空比控制所述水泵以该水泵占空比运行，以调控冷却液的流量，使冷却液在循环过程中不断吸收驱动***中驱动电机所产生的热量；根据所述风扇转速控制所述风扇以该风扇转速运行，使风扇加快空气的流动，使得驱动***所产生的热量能与流动空气进行热交换，达到散热的目的。同时，提升了驱动电机运行的使用寿命，降低了因此类问题带来的车辆维护成本。
请参阅图5，本公开一示例性实施例还提供一种用于车辆的冷却控制方法，所述冷却控制方法包括步骤S21至步骤S23。
步骤S21：获取油门的当前开度信号和用于冷却所述车辆的驱动***的冷却液的当前温度。
步骤S21与图1中的步骤S11类似，此处不再赘述。
步骤S22：在获取的所述当前开度信号连续n个均大于预设的开度值的情况下，选取n个所述当前开度信号中的任意一个当前开度信号，并根据该当前开度信号和所述当前温度，确定目标设备的运行参数。
需要说明的是，n为自然正整数，根据实际情况设定即可。本实施例对此不做任何限定。
需要说明的是，预设的开度值可以根据实际情况设定即可。本实施例对此不做任何 限定。
可以理解的是，为进一步降低驱动***存在过热的风险，由于油门的开度信号越大(油门需求越大)，驱动***越容易产生过热的现象，因此，所述电子设备可选取n个所述当前开度信号中最大的当前开度信号作为确定目标设备的运行参数的依据，以确保最大程度上避免驱动***产生过热的情况。
步骤S23：根据所述运行参数，控制所述目标设备的运行状态，以对所述驱动***进行降温。
步骤S23与图1中的步骤S13类似，此处不再赘述。
在本实施例中，在所述电子设备连续获取的n个所述当前开度信号均大于预设的开度值的情况下，再根据获取的n个所述当前开度信号中的一个当前开度信号和所述当前温度确定目标设备的运行参数，以避免瞬时的大的油门需求或单个数据异常造成所述电子设备和目标设备执行不必要的操作，减少了不必要的电量消耗。
