相关申请的交叉引用
本申请要求于2022年06月17日提交、申请号为202210690832.5的中国专利申请的优先权，其全部内容通过引用合并于此。
技术领域
本公开涉及车辆发电机控制领域，尤其涉及一种车辆发电机控制方法及相关设备。
背景技术
泄压阀一般布置在中冷后，用于松油门时将中冷后的气体通过泄压阀排出，从而将多余能量消耗掉，其主要作用为避免多余气体留存在发动机内发生喘振，导致增压器异响。而泄压阀会增加成本并会影响系统结构的复杂度。但是，简单地取消泄压阀又会由于多余的气体不能排出而导致发动机内发生喘振。
发明内容
通过利用本公开提供的一个或多个实施方式，提供了一种车辆发电机控制方法及相关设备，以解决低温情况下车辆能量难以通过电池回充，故缺少一种更好的控制发电机消耗能量的方法的问题。
在本公开的第一方面，提供了一种车辆发电机控制方法，该方法包括：获取电池温度；在上述电池温度低于预设温度的情况下，获取动力总控制器发送给发电机的目标待消耗功率，上述目标待消耗功率是基于消耗发动机待泄压力的所需功率确定的；基于上述目标待消耗功率控制车辆发电机工作，以消耗至少部分上述目标待消耗功率。
在本公开的第二方面，提供了一种车辆发电机控制装置，包括：第一获取单元，用于获取电池温度；第二获取单元，用于在上述电池温度低于预设温度的情况下，获取动力总控制器发送给发电机的目标待消耗功率，上述目标待消耗功率是基于消耗发动机待泄压力的所需功率确定的；控制单元，用于基于上述目标待消耗功率控制车辆发电机工作，以消耗至少部分上述目标待消耗功率。
在本公开的第三方面，提供了一种计算机可读存储介质，该计算机可 读存储介质包括存储的程序，其中，在上述程序被处理器执行时实现上述的车辆发电机控制方法。
在本公开的第四方面，提供了一种电子设备，包括至少一个处理器、以及与上述处理器连接的至少一个存储器；其中，上述处理器用于调用上述存储器中的程序指令，执行上述的车辆发电机控制方法。
上述说明仅是本公开技术方案的概述，为了能够更清楚了解本公开的技术手段，而可依照说明书的内容予以实施，并且为了让本公开的上述和其它目的、特征和优点能够更明显易懂，以下特举本公开的一些实施方式。
附图说明
通过阅读下文优选实施方式的详细描述，各种其他的优点和益处对于本领域普通技术人员将变得清楚明了。附图仅用于示出优选实施方式的目的，而并不认为是对本公开的限制。而且在整个附图中，用相同的参考符号表示相同的部件。在附图中：
图1示出了依据本公开一些实施方式的车辆发电机控制方法的流程示意图；
图2示出了依据本公开一些实施方式的车辆发电机控制装置的组成示意框图；以及
图3示出了依据本公开一些实施方式的电子设备的组成示意框图。
具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
为了解决低温情况下车辆能量难以通过电池回充，故缺少一种更好的控制发电机消耗能量的方法的问题，本公开提供了一种车辆发电机控制方法。如图1所示，该方法包括步骤S101至S103。
S101、获取电池温度。
在一些实施方式中，可以通过温度传感器等设备获取电池温度，方便基于此数据确定是否执行本公开的车辆发电机控制方法。
S102、在上述电池温度低于预设温度的情况下，获取动力总控制器发送给发电机的目标待消耗功率，上述目标待消耗功率是基于消耗发动机待泄压力的所需功率确定的。
在上述电池温度低于预设温度的情况下，证明温度过低，电池回充能力受限，无法将功率转化成电能存储起来，故仍存在没有被消耗的功率。假设车辆以x功率行驶，那么当用户松开油门期望降车速至停止时，在没有了泄压阀之后，气体通过节气门出去，这部分气体对应的功率需要被消耗掉，即x功率应该被全部消耗掉，上述x功率即为上述消耗发动机待泄压力的所需功率，基于上述消耗发动机待泄压力的所需功率确定上述目标待消耗功率即还需发电机消耗的功率。
S103、基于上述目标待消耗功率控制车辆发电机工作，以消耗至少部分上述目标待消耗功率。
在一些实施方式中，在确定上述目标待消耗功率即还需发电机消耗的功率之后，基于此功率控制车辆发电机工作，能够消耗至少部分上述目标待消耗功率，使车辆的功率降下，从而保证能量被消耗掉，防止喘振的发生。
本公开提供的车辆发电机控制方法，对于低温情况下车辆能量难以通过电池回充，故缺少一种更好的控制发电机消耗能量的方法的问题，本公开通过获取电池温度；在上述电池温度低于预设温度的情况下，获取动力总控制器发送给发电机的目标待消耗功率，上述目标待消耗功率是基于消耗发动机待泄压力的所需功率确定的；基于上述目标待消耗功率控制车辆发电机工作，以消耗至少部分上述目标待消耗功率。在上述方案中，通过设定预设温度，控制本方法的实现是基于当温度过低的情况下，电池回充能力受限，导致存在多余的能量需要进行消耗时再执行本方案，动力总控制器统计出还需消耗多少能量及其对应的功率，以及对应的发电机还需消耗的功率，并基于此功率控制发电机工作，将这部分多余的能量消耗出去，达到取消泄压阀后车辆的能量仍达到平衡，防止喘振的发生。
在一些实施方式中，上述目标待消耗功率是消耗发动机待泄压力的所需功率除去其他器件可消耗功率后的待消耗剩余功率。
车辆上有很多零部件都可以通过运行消耗掉一部分待泄功率，故上述目标待消耗功率即为消耗发动机待泄压力的所需功率除去其他器件可消耗功率后的待消耗剩余功率，才是发电机需要消耗的功率。通过将其他器件可消 耗功率除去，基于上述目标待消耗功率控制发电机运行保证了发电机运行功率的准确性。
在一些实施方式中，上述其他器件可消耗功率为喷油量消耗功率、节气门消耗功率和电池回充消耗功率的总和。
消耗上述功率的方法可以有多种，例如，可以通过控制喷油量和节气门开度将其转化为电能为电池回充，但是控制喷油量和节气门开度只能消耗掉一小部分，而电池回充也因温度过低受限，故确定上述目标待消耗功率即还需发电机消耗的功率等于上述消耗发动机待泄压力的所需功率除去控制喷油量、节气门开度和将其转化为电能为电池回充后的功率的剩余功率，若有其他器件也可计算在内，将已消耗的功率排除在外，从而保证了所计算出的上述目标待消耗功率的准确性。
在一些实施方式中，上述基于上述目标待消耗功率控制车辆发电机工作，以消耗至少部分上述目标待消耗功率，包括：基于上述目标待消耗功率和上述预设标准功率，控制车辆发电机工作，以消耗至少部分上述目标待消耗功率；其中，上述预设标准功率包括：第一预设标准功率和第二预设标准功率，上述第一预设标准功率为电池加热器额定功率与其他附件加热器额定功率之和，上述第二预设标准功率为上述发电机可接受的最大输入功率，上述第一预设标准功率小于上述第二预设标准功率。
在一些实施方式中，上述第一预设标准功率可以为电池加热器额定功率与其他附件加热器额定功率之和。此阈值为基础阈值，在此阈值之下，功率可以完全被电池加热器和其他附件消耗掉，若超过此阈值，上述电池加热器和其他附件加热器的温度会过高。上述第二预设标准功率可以为上述发电机可接受的最大输入功率，包括：电池加热器和其他附件的功率之和加台架验证发电机10s内不报故障的功率的总和，此阈值为发电机工作的上限阈值，用于规定发电机的工作功率不能超负荷工作。
在一些实施方式中，上述基于上述目标待消耗功率和上述预设标准功率，控制车辆发电机工作，以消耗至少部分上述目标待消耗功率，包括：在上述目标待消耗功率小于或等于上述第一预设标准功率的情况下，控制上述发电机根据上述目标待消耗功率工作，为上述电池加热器和上述其他附件加热器供电发热。
示例性的，假定上述目标待消耗功率为10，上述第一预设标准功率为 15，因10<15，在此情况下，证明上述电池加热器和上述其他附件加热器即可消耗掉上述目标待消耗功率，则控制发电机按照上述目标待消耗功率即10发电，将电能传输至上述电池加热器和上述其他附件加热器发热，将多余功率消耗掉的同时还为电池进行了升温。
在一些实施方式中，上述基于上述目标待消耗功率和上述预设标准功率，控制车辆发电机工作，以消耗至少部分上述目标待消耗功率，包括：在上述目标待消耗功率大于上述第一预设标准功率且小于或等于上述第二预设标准功率的情况下，控制上述发电机根据上述第一预设标准功率工作，为上述电池加热器和上述其他附件加热器供电发热；控制上述发电机以上述目标待消耗功率除去上述第一预设标准功率后的剩余待消耗功率产热。
示例性的，假定上述目标待消耗功率为10，上述第一预设标准功率为8，上述第二预设标准功率为15，因8<10<15，在此情况下，证明上述电池加热器和上述其他附件加热器无法完全消耗掉上述目标待消耗功率，此时，控制发电机按照第一预设标准功率发电，此时只通过上述电池加热器和上述其他附件加热器消耗掉了8的功率，仍有2的功率没有被消耗，此时控制发电机自身工作发热，将这部分2的功率消耗掉，将多余功率消耗掉的同时还为电池进行了升温。
在一些实施方式中，上述基于上述目标待消耗功率和上述预设标准功率，控制车辆发电机工作，以消耗至少部分上述目标待消耗功率，包括：在上述目标待消耗功率大于上述第二预设标准功率的情况下，控制上述发电机根据上述第一预设标准功率工作，为上述电池加热器和上述其他附件加热器供电发热；控制上述发电机以上述第二预设标准功率除去上述第一预设标准功率后的剩余待消耗功率产热，并向上述动力总控制器发出告警，其中，上述告警包括向上述动力总控制器申请降低上述目标待消耗功率。
示例性的，假定上述目标待消耗功率为10，上述第一预设标准功率为5，上述第二预设标准功率为8，因8<10，故上述发电机无法承受以10的功率工作，此时，先控制发电机按照第一预设标准功率即5的功率为上述电池加热器和上述其他附件加热器供电发热，然后再按照8-5＝3的功率自身工作发热，同时向上一级控制系统即上述动力总控制器发出告警，提醒上述动力总控制器负荷过大，申请降低上述目标待消耗功率。从而在需要上述发电机工作的负荷超出上述发电机承受范围的情况下，保证发电机安全工作的同时，尽自身最大可能消耗功率。
