Description

一种能量协调控制方法、系统及车辆
本申请要求在2020年03月10日提交中国专利局、申请号为202010162805.1、名称为“一种能量协调控制方法、系统及车辆”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本公开涉及汽车技术领域，特别涉及一种能量协调控制方法、系统及车辆。
背景技术
当前，随着全球环保问题的日益严重，新能源汽车得以快速发展。新能源汽车具有充电功能，利用该充电功能可以将电网中的电能输送到电池包中，然后利用电池包中的电能驱动车辆行驶，从而实现无油耗、无排放的行程。
混合动力汽车为可利用电能及化石能源驱动的新能源汽车，其动力电池包相对于纯电动汽车的动力电池包较小，配套的车载充电机也相对较小，使得混合动力汽车的充电机功率大都小于空调的额定功率。若用户在混合动力汽车充电时使用空调，由于空调正常工作消耗的功率大于充电机输出的功率，为了维持空调的正常使用，需要动力电池包放电以向空调供电，这势必会影响电池包的正常充电。
针对空调的使用会影响电池包充电的情况，现有技术采用的是限制空调功率的方式，即在汽车充电并开启空调时，将空调的功率限制在较低的限值，以确保电池能够正常充电。但由于空调功率被限制，导致车内温度调控速率变慢，因而影响了用户体验。
概述
有鉴于此，本公开旨在提出一种能量协调控制方法、系统及车辆，以解决现有混合动力汽车充电时无法正常使用空调，导致车内温度调控速率变慢，容易给驾乘人员带来不便的问题。
为达到上述目的，本公开的技术方案是这样实现的：
一种能量协调控制方法，应用于车辆，所述车辆包括发动机、发电机、电池、充电机及空调，所述发电机与所述发动机机械连接，所述发电机及所述充电机均与所述电池电连接，所述充电机及所述电池均与所述空调电连接，其中，所述发电机与所述空调电连接，所述方法包括：
在监测到充电信号时，控制所述充电机为所述电池充电，并监测所述空调的空调信号；
若根据所述空调信号，确定所述空调有用电需求，则控制所述发动机启动，以驱动所述发电机为所述空调供电。
进一步地，所述的方法中，所述若根据所述空调信号，确定所述空调有用电需求，则控制所述发动机启动，以驱动所述发电机为所述空调供电，包括：
若监测到所述空调的开启信号，则控制所述发动机启动，以驱动所述发电机为所述空调供电。
进一步地，所述的方法中，所述若根据所述空调信号，确定所述空调有用电需求，则控制所述发动机启动，以驱动所述发电机为所述空调供电，还包括：
若检测到所述空调处于开启状态，则控制所述发动机启动，以驱动所述发电机为所述空调供电，并控制所述电池停止为所述空调供电。
进一步地，所述方法，还包括：
在所述充电机为所述电池充电时，若监测到所述空调的关闭信号，则控制所述空调关闭，并控制所述发动机关闭。
进一步地，所述的方法中，所述控制所述发动机启动，以驱动所述发电机为所述空调供电，具体包括：
获取所述空调的目标消耗功率；
控制所述发动机启动，以驱动所述发电机按所述目标消耗功率为所述空调供电。
本公开实施例的另一目的还在于提出一种能量协调控制系统，应用于车辆，所述车辆包括发动机、发电机、电池、充电机及空调，所述发电机与所 述发动机机械连接，所述发电机及所述充电机均与所述电池电连接，所述充电机及所述电池均与所述空调电连接，其中，所述发电机与所述空调电连接，所述系统包括：
第一控制模块，用于在监测到充电信号时，控制所述充电机为所述电池充电，并监测所述空调的空调信号；
第二控制模块，用于若根据所述空调信号，确定所述空调有用电需求，则控制所述发动机启动，以驱动所述发电机为所述空调供电。
进一步地，所述的系统中，所述第二控制模块，包括：
第一控制单元，用于若监测到所述空调的开启信号，则控制所述空调开启，并控制所述发动机启动，以驱动所述发电机发为所述空调供电。
进一步地，所述的系统中，所述第二控制模块，还包括：
第二控制单元，用于若监测到所述空调处于开启状态，则控制所述发动机启动，以驱动所述发电机为所述空调供电，并控制所述电池停止为所述空调供电。
进一步地，所述的系统，还包括：
第三控制模块，用于在所述充电机为所述电池充电时，若监测到所述空调的关闭信号，则控制所述空调关闭，并控制所述发动机关闭。
进一步地，所述的系统中，所述第二控制模块，具体用于若根据所述空调信号，确定所述空调有用电需求，则获取所述空调的目标消耗功率，并控制所述发动机启动，以驱动所述发电机按所述目标消耗功率为所述空调供电。
本公开的再一目的在于提出一种车辆，所述车辆包括发动机、发电机、电池、充电机及空调，所述发电机与所述发动机机械连接，所述发电机及所述充电机均与所述电池电连接，所述充电机及所述电池均与所述空调电连接，其中，所述发电机与所述空调电连接，所述车辆还包括所述的能量协调控制系统。
相对于在先技术，本公开所述的能量协调控制方法、系统及车辆具有以下优势：
在监测到充电信号时，控制所述充电机为所述电池充电，并监测所述空调的空调信号；若根据上述空调信号确定所述空调有用电需求，则控制所述 发动机启动，以驱动所述发电机向所述空调供电。因为若在给电池充电时空调有用电需求，是启动发动机驱动发电机为空调供电，使得空调的运行无需利用充电机或电池包的电能，也即不会影响电池的充电功率，也能够保证空调的正常使用，从而解决了现有混合动力汽车充电时无法正常使用空调，导致车内温度调控速率变慢，容易给驾乘人员带来不便的问题。

需要说明的是，在不冲突的情况下，本公开中的实施例及实施例中的特征可以相互组合。
下面将参考附图并结合实施例来详细说明本公开。
请参阅图1，示出了本公开实施例所提供的一种能量协调控制方法的流程示意图，本公开实施例所提供的能量协调控制方法，应用于车辆，所述车辆包括发动机、发电机、电池、充电机及空调，所述发电机与所述发动机机械连接，所述发电机及所述充电机均与所述电池电连接，所述电池与所述空调电连接，其中，所述发电机与所述空调电连接，所述方法包括步骤S100～S200。
本公开实施例所提供的能量协调控制方法，适用于混合动力车辆，该车辆包括发动机、发电机、电池、充电机及空调；其中，发电机与发动机机械连接，因而可以利用发动机带动发电机发电；而充电机与电池电连接，因而可以利用充电机直接为电池充电；同时，发电机也与电池电连接，因而可以在需要回收能量时，可以利用发电机将发动机处的机械能转化为电能，并将发电机产生的电能输入电池中进行存储；而电池与所述空调电连接，因而可以利用电池为空调供电，以满足空调的工作；另外，因为空调还与发电机电连接，因而可以在空调有用电需求时，控制发电机为空调供电。
在实际应用中，充电机也可与空调电连接，因而也可以直接利用充电机为空调供电。
步骤S100、在监测到充电信号时，控制所述充电机为所述电池充电，并监测所述空调的空调信号。
上述步骤S100中，在监测充电信号时，即说明需要给电池充电；而因为充电机与电池电连接，因而可以在监测到充电信号时，直接控制充电机将电网中的电能按一定功率输送到电池中，使得电池进入充电状态，进而实现对电池的充电。
在实际应用中，该充电信号可以是充电机的输入端处的电压信号，因为在充电机与外部电网接通时，其输入端的电压信号发生变化，此时即可以判定需要给电池充电。
上述步骤S100中，还需在监测到充电信号之后，监测空调的空调信号，以根据上述空调信号确定空调是否有用电需求，即监测空调是否需要用电以进行工作，以便于后续确实是否需要开启发动机为空调供电。该空调信号具体可以包括空调所处状态信号以及空调的开启信号及关闭信号。其中，若监测到开启状态信号，说明空调当前处于开启状态，则空调有用电需求；若监测到空调的开启信号，则说明虽然空调当前处于关闭状态，但其需要开启并进入运行状态，因而空调也有用电需求；而若检测到空调的关闭信号，则说明虽然空调当前处于运行状态，但其需要关闭并进入关闭状态，因而空调不再需要用电，也即无用电需求。
步骤S200、若根据所述空调信号，确实所述空调有用电需求，则控制所述发动机启动，以驱动所述发电机向所述空调供电。
在上述步骤S200中，即在监测到充电信号后，若还根据空调信号确定了所述空调有用电需求，则说明需要向空调供电，此时控制发动机启动，进而可以控制发动机驱动发电机发电；而因为空调与发电机电连接，因而可以利用发动机驱动发电机产出的电能为空调供电，从而驱动空调的运行。因为有发动机驱动发电机为空调供电，因而无需再利用充电机或电池为空调供电，也即不会影响电池的充电功率及充电效率，又能够保证空调的正常运行。
具体地，上述控制所述发动机启动，以驱动所述发电机向所述空调供电的步骤，具体包括步骤S201～S202。
步骤S201、获取所述空调的目标消耗功率。
上述步骤S201中，空调的目标消耗功率指的是空调的耗电功率，即空调达到目标运行状态所需要消耗的电功率，可以直接由空调为达到目标运行 状态的各运行参数计算得到。上述步骤S201中，获取空调的目标消耗功率，以便于后续控制发动机驱动发电机的发电功率。
在实际应用中，上述目标消耗功率P AC可以根据高压加热器的消耗功率P PTC与制冷压缩机的消耗功率P CMP之和计算得到，其中，P PTC可由高压加热器的工作电流及电压计算得到，而P CMP由制冷压缩机的工作电流及电压计算得到。具体地，由以下公式进行计算：
P AC＝P PTC+P CMP  (1)
P PTC＝U PTC×I PTC  (2)
P CMP＝U CMP×I CMP  (3)
公式(1)～(3)中，P AC是空调消耗功率，P PTC是高压加热器消耗功率，P CMP为制冷压缩机消耗功率，U PTC及I PTC分别为高压加热器的工作电压及工作电流，U CMP及I CMP分别为制冷压缩机的工作电压及工作电流。
步骤S202、控制所述发动机启动，以驱动所述发电机按所述目标消耗功率为所述空调供电。
因为发动机与发电机机械连接，因而可以控制发动机驱动发电机发电，而且可以通过控制发动机的转速及发电机的磁场变化，对发电机的输出电能进行调整。在上述步骤S202中，在发动机启动后，不仅控制所述发动机驱动所述发电机发电，而且控制所述发电机按空调所述需要的目标消耗功率为空调供电，即控制发电机按照空调所需要消耗的电功率进行发电，这样既可以使得空调可以按目标工作状态进行工作，且无需电池向空调供电，又不会让发动机驱动发电机发出超出空调所需的电量而造成能量浪费。
另外，若接收到停止充电信号时，若所述空调处于运行状态，则控制所述电池为所述空调供电，并控制所述发动机关闭，以利用电池中更为清洁的电能直接驱动空调，避免过多地使用化石能源驱动发动机带动发电机为空调供电。
相对于现有技术，本公开所述的车辆空调控制方法具有以下优势：
在监测到充电信号时，控制所述充电机为所述电池充电，并监测所述空调的空调信号；若根据上述空调信号确定所述空调有用电需求，则控制所述发动机启动，以驱动所述发电机向所述空调供电。因为若在给电池充电时空 调有用电需求，是启动发动机驱动发电机为空调供电，因而空调的运行无需利用充电机或电池包的电能，也即不会影响电池的充电功率，也能够保证空调的正常使用，从而解决了现有混合动力汽车充电时无法正常使用空调，导致车内温度调控速率变慢，容易给驾乘人员带来不便的问题。
可选地，在一种实施方式中，上述步骤S200包括步骤S211：
步骤S211、若监测到所述空调的开启信号，则控制所述空调开启，并控制所述发动机启动，以驱动所述发电机向所述空调供电。
即在充电机为电池充电的过程中，若监测到所述空调的开启信号，则说明虽然空调当前处于关闭状态，但其需要开启并进入运行状态，也即确定空调有用电需求。此时控制发动机启动，进而可以控制发动机驱动发电机发电；而因为空调与发电机电连接，因而可以利用发动机驱动发电机产出的电能为空调供电，从而驱动空调的运行。因为有发动机驱动发电机为空调供电，所以无需再利用充电机或电池为空调供电，也即不会影响电池的充电功率及充电效率，又能够保证空调的正常运行。
可选地，在一种实施方式中，上述步骤S200包括步骤S212：
步骤S212、若监测到所述空调处于开启状态，则控制所述发动机启动，以驱动所述发电机为所述空调供电，并控制所述电池停止为所述空调供电。
在上述步骤S212中，在监测到充电信号时，若监测到空调已经处于运行状态，此时，空调有用电需求，且当前是由电池为空调供电以满足空调的目标消耗功率；而在监测到充电信号时，又需要控制充电机给电池充电，为了避免影响电池的充电效率，控制发动机驱动发电机按空调的目标消耗功率为空调供电，使得空调无需再由电池供电，也就不会影响充电机为电池充电的功率及效率。
可选地，在一种实施方式中，本公开实施例所提供的能量协调控制方法，在步骤S200之后，还包括步骤S300：
步骤S300、在所述充电机为所述电池充电时，若监测到所述空调的关闭信号，则控制所述空调关闭，并控制所述发动机关闭。
上述步骤S300中，在监测到充电信号后，会控制电池进入充电状态，此时若监测到所述空调的关闭信号，则说明空调当前处于运行状态，且当前 是由发动机驱动发电机为空调供电，且需要关停空调，因而控制空调关闭；此时，因为空调不再消耗电能，也即无需发电机再向其供电，因而控制发动机关闭。另外，因为此时充电机仍在为电池充电，充电机可以满足电池的电能需求，在空调关闭后，控制发动机关闭，不仅可以避免能量浪费，还可以避免因充电功率过大而损害电池。
请参阅图2，示出了本公开一优选实施例所提供的一种能量协调控制方法的流程示意图，应用于车辆，所述车辆包括发动机、发电机、电池、充电机及空调，所述发电机与所述发动机机械连接，所述发电机及所述充电机均与所述电池电连接，所述电池与所述空调电连接，其中，所述发电机与所述空调电连接，所述方法包括步骤S221～S224。
步骤S221、在监测到充电信号时，控制所述充电机为所述电池充电，并监测所述空调的空调信号。
上述步骤S221可参照步骤S100的详细说明，此处不再赘述。
步骤S222、若监测到所述空调的开启信号，则控制所述空调开启，并控制所述发动机启动，以驱动所述发电机为所述空调供电。
上述步骤S222可参照步骤S211的详细说明，此处不再赘述。
步骤S223、若监测到所述空调处于开启状态，则控制所述发动机启动，以驱动所述发电机为所述空调供电，并控制所述电池停止为所述空调供电。
上述步骤S223可参照步骤S212的详细说明，此处不再赘述。
步骤S224、在所述充电机为所述电池充电时，若监测到所述空调的关闭信号，则控制所述空调关闭，并控制所述发动机关闭。
上述步骤S224可参照步骤S300的详细说明，此处不再赘述。
相对于现有技术，本公开实施例所述的能量协调控制方法具有以下优势：
在控制所述充电机为所述电池充电的开始阶段，若空调处于开启状态，则控制发动机启动以控制发动机驱动发电机为所述空调供电，同时控制电池停止为所述空调供电；以及，在所述充电机为所述电池充电时，若监测到所述空调的开启信号，则控制所述发动机启动，并控制所述发动机驱动所述发电机发电，并控制所述发电机为所述空调供电；因而可以在利用充电机给电池充电时，若需要使用空调，均启动发动机驱动发电机为空调供电，使得空 调的运行无需利用充电机或电池包的电能，也即不会影响电池的充电功率，也能够保证空调的正常使用，从而解决了现有混合动力汽车充电时无法正常使用空调，导致车内温度调控速率变慢，容易给驾乘人员带来不便的问题。
在实际应用中，请参阅图3，示出了本公开实施例所提出的能量协调控制方法的执行流程图。
如图3所示，在步骤S301中，检测电池是否开始充电；在电池开始充电时，则进入步骤S302；
在步骤S302中，判断空调是否被打开；若空调开启，则进入步骤S303中；若空调未打开，则进入步骤S306中；
在步骤S303中，通过控制发动机启动带动发电机发电；然后在步骤S304中检测空调消耗功率，并在步骤S305中，控制发动机按照空调消耗功率进行发电，从而满足空调的运行需求；
在步骤S306中，按照正常策略控制充电能量管理，即在没有空调使用需求时，控制充电机按照电池的正常功率需求进行充电。
在实际应用中，请参阅图4，示出了本公开实施例所提出的能量协调控制方法的控制原理图。如图4所示，上述控制方法由空调状态检测模块41、充电状态控制模块42、发动机启停模块43、能量协调模块44及发电机模块45共同完成。
其中，空调状态检测模块41用于判断空调是否开启，并将判断结果上报至能量协调模块44，同时用于根据高压加热器及制冷压缩机的电压、电流计算空调消耗功率；而充电状态控制模块42则用于控制整车充电流程，具有用于在用户执行充电动作后控制车辆进入充电状态，以及在用户执行充电停止动作或电池充满后控制车辆停止充电；发动机启动模块43则用于在接收到发动机启动信号后，按照预先定义的流程启动发动机，以及在接收到停机信号是关闭发动机；而能量协调模块44用于具体执行上述能量协调控制方法；发电机模块45则用于在发动机启动后将发动机产生的机械能转化为电能以供空调消耗，其中，发电功率等于能量协调模块44请求功率。
本公开的另一目标在于提出一种能量协调控制系统，应用于车辆，所述车辆包括发动机、发电机、电池、充电机及空调，所述发电机与所述发动机 机械连接，所述发电机及所述充电机均与所述电池电连接，所述充电机及所述电池均与所述空调电连接，其中，请参阅图5，图5示出了本公开实施例所提出的一种能量协调控制系统的结构示意图，所述系统包括：
第一控制模块10，用于在监测到充电信号时，控制所述充电机为所述电池充电，并监测所述空调的空调信号；
第二控制模块20，用于若根据所述空调信号，确定所述空调有用电需求，则控制所述发动机启动，以驱动所述发电机为所述空调供电。
本公开实施例所述的系统，在监测到充电信号时，由第一控制模块10控制充电机为电池充电，并监测空调的空调信号；再在根据上述空调信号确定空调有用电需求时，由第二控制模块20控制发动机启动，以驱动发电机为上述空调供电。因为若在给电池充电时空调有用电需求，是启动发动机驱动发电机为空调供电，使得空调的运行无需利用充电机或电池包的电能，也即不会影响电池的充电功率，也能够保证空调的正常使用，从而解决了现有混合动力汽车充电时无法正常使用空调，导致车内温度调控速率变慢，容易给驾乘人员带来不便的问题。
可选地，所述的系统中，所述第二控制模块20，包括：
第一控制单元，用于若监测到所述空调的开启信号，则控制所述空调开启，并控制所述发动机启动，以驱动所述发电机发为所述空调供电。
可选地，所述的系统中，所述第二控制模块20，还包括：
第二控制单元，用于若监测到所述空调处于开启状态，则控制所述发动机启动，以驱动所述发电机为所述空调供电，并控制所述电池停止为所述空调供电。
可选地，所述的系统，还包括：
第三控制模块，用于在所述充电机为所述电池充电时，若监测到所述空调的关闭信号，则控制所述空调关闭，并控制所述发动机关闭。
可选地，所述的系统中，所述第二控制模块20，具体用于若根据所述空调信号，确定所述空调有用电需求，则获取所述空调的目标消耗功率，并控制所述发动机启动，以驱动所述发电机按所述目标消耗功率为所述空调供电。
本公开的再一目的在于提出一种车辆，所述车辆包括发动机、发电机、 电池、充电机及空调，所述发电机与所述发动机机械连接，所述发电机及所述充电机均与所述电池电连接，所述充电机及所述电池均与所述空调电连接，其中，所述发电机与所述空调电连接，所述车辆还包括所述的能量协调控制系统。
所述能量协调控制控制系统、车辆与上述能量协调控制方法相对于现有技术所具有的优势相同，在此不再赘述
综上所述，本申请提供的能量协调控制方法、系统及车辆，在监测到充电信号时，控制所述充电机为所述电池充电，并监测所述空调的空调信号；然后根据上述空调信息确定空调是否有用电需求；若根据上述空调信号确定所述空调有用电需求，则控制所述发动机启动，以驱动所述发电机向所述空调供电。因为若在给电池充电时空调有用电需求，是启动发动机驱动发电机为空调供电，使得空调的运行无需利用充电机或电池包的电能，也即不会影响电池的充电功率，也能够保证空调的正常使用，从而解决了现有混合动力汽车充电时无法正常使用空调，导致车内温度调控速率变慢，容易给驾乘人员带来不便的问题。
所属领域的技术人员可以清楚地了解到，为描述的方便和简洁，上述描述的系统、装置和单元的具体工作过程，可以参考前述方法实施例中的对应过程，在此不再赘述。
