通过上述附图，已示出本申请明确的实施例，后文中将有更详细的描述。这些附图和文字描述并不是为了通过任何方式限制本申请构思的范围，而是通过参考特定实施例为本领域技术人员说明本申请的概念。
具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一致的装置和方法的例子。
车辆中热管理热泵的热量来源一般来自于外部蒸发器的低温吸热及电池热交换器的余热回收，目前，现有的车辆在进行余热回收时，通常是对废气余热回收、发动机冷却水余热回收、制动能量回收等方式进行回收，然而在对废气余热回收、发动机冷却水余热回收、制动能量回收等方式进行回收时，一般不会考虑到车辆所处的环境温度和车内温度，从而使得车辆通过余热回收而进行热管理时，热管理能耗高，能耗较大，使得热管理过程中的制热效率较低。
为了解决上述问题，本申请提供的车辆控制方法，可以根据环境温度和车内温度来确定是否对车辆进行加热，并使得当环境温度和车内温度高于第二预设温度时，对车辆进行驾驶舱余热的余热回收，由此，可以有效利用驾驶舱余热，实现提高热管理过程中的制热效率的效果。
本申请实施例提供的车辆控制方法的执行主体可以是服务器。其中，服务器可以为手机、平板、电脑、车载电脑等设备。本实施例对执行主体的实现方式不做特别限制，只要该执行主体能够获取车辆的环境温度和车内温度；根据环境温度和车内温度，对车辆的内部进行加热；当环境温度 或车内温度高于第二预设温度时，对车辆内的驾驶舱进行余热回收，以对车辆进行热管理即可。
其中，热管理是指车内动态的热量管理，能够节能高效地管理整车热流(包含对电池、电机、电控以及乘客舱等的制热及制冷管理)，有效延长电动汽车冬季和夏季的续航里程。
车辆余热回收是指利用车辆运行过程中产生的废热，通过热交换技术将其回收并转化为能量，以提高车辆的能源利用效率。
图1为本申请实施例提供的车辆控制方法的流程示意图。该方法的执行主体可以为服务器或其它服务器，本实施例此处不做特别限制，如图1所示，该方法可以包括：
S101、获取车辆的环境温度和车内温度。
其中，环境温度可以指车辆所处环境的问题。
车内温度可以指车辆内部的温度。其中，车辆内部可以为车辆内的电池舱，也可以为车辆内部的发动机舱，以及汽车的内舱。
获取车辆的环境温度和车内温度的方法可以包括通过车辆外和车辆内设置的温度传感器检测的。在本申请实施例中，车辆的环境温度和车内温度可以根据车辆内的空调确定。
S102、根据环境温度和车内温度，对车辆的内部进行加热。
其中，对车辆的内部进行加热可以指通过热泵系统中包括的空调主机、压缩机、水冷式冷凝器、热管理模块、chiller(制冷设备，包括冷凝器和蒸发器)、HVCH(高压液体加热器)。
其中，在本申请实施例中，根据环境温度和车内温度，对车辆的内部进行加热的方法包括：
当环境温度处于第一预设温度和第二预设温度之间时、或当环境温度处于第二预设温度和第三预设温度之间、且车内温度高于第二预设温度时、或当环境温度低于第三预设温度、且车内温度高于第二预设温度时，
控制加热器和冷凝器对车辆的内部进行加热，其中，第一预设温度高于第二预设温度、第二预设温度高于第三预设温度。
其中，第一预设温度高于第二预设温度、第二预设温度高于第三预设温度可以为预先设置的任意温度，也可以是根据车辆在实际使用时的特点设置的，比如，第一预设温度可以为根据车辆内人员所需要的温度，例如、 第一预设温度可以为15℃；第二预设温度可以为根据车辆内热泵系统对车内进行加热的温度，例如、第二预设温度可以为-10℃；第三预设温度可以根据车辆内冷却液的特性确定，例如、冷却液在-20℃上、可以正常使用时，则第三预设温度可以为-20℃。
加热器可以指高压液体加热器，是一种用于汽车空调系统的热交换器，它通过将高压制冷剂传递到加热器中，将其加热并将热量传递到车内空气中，从而提供暖气。
冷凝器可以是一种用于汽车空调系统的组件，其作用是将空气中的水蒸气冷凝成液态水，从而降低空气中的湿度。其中，冷凝器通常与蒸发器一起使用，以便在汽车内部维持舒适的温度和湿度。在本申请实施例中，控制冷凝器对车辆的内部进行加热的方法可以为开启电动压缩机和冷凝风扇，从而使得冷凝器向车内进行放热。
其中，在本申请实施例中，根据环境温度和车内温度，对车辆的内部进行加热的方法可以包括：
当环境温度低于第三预设温度、且车内温度低于第二预设温度时，加热车辆内空调水路中冷却液，以对车辆进行预加热，其中，第三预设温度低于第二预设温度；
检测冷却液的冷却液温度；

其中，冷却液温度可以指冷却液的温度，冷却液温度可以通过设置在水路上的传感器得到。
当环境温度低于第三预设温度时，表征冷却液无法正常使用，因此，需要对冷却液进行加热，以提高冷却液温度，方便空调主机等热泵中其他设备的使用，同时当冷却液的温度提高后，冷却液也可以对车辆进行预加热，由此，提高了车内温度。
在当冷却液温度高于第三预设温度时，可以通过热泵的设备对车辆的内部进行加热。
在本申请实施例中，第三预设温度可以为-20℃，第二预设温度可以为-10℃。其中，在本申请实施例中，当环境温度低于第三预设温度、且车内温度低于第二预设温度时，加热车辆内空调水路中冷却液，以对车辆进行预加热，包括：
环境温度低于第三预设温度、且车辆的内部温度低于第二预设温度，控制车辆内的加热器开启、电机堵转加热冷却液，以对车辆内部进行预加热。
其中，电机堵转可以是指电机在运行过程中由于某些原因，无法正常旋转或旋转受阻，导致电机电流急剧升高，甚至超过额定电流，从而引起电机过热的现象。在本申请实施例中，由于环境温度低于第三预设温度，即表征当前环境温度过低，因此，在使得电机堵转时，通过电机堵转对冷却液进行加热，可以有效避免电机出现过热等问题，并快速加热冷却液。
其中，在本申请实施例中，当冷却液温度高于第三预设温度时，对车辆的内部进行加热，包括：
当冷却液温度高于第三预设温度时，控制电机退出堵转；
在电机退出堵转后，开启冷凝器对车辆的内部进行加热。
其中，当冷却液温度高于第三预设温度时，对冷却液的加热效果降低，由此，电机可能会出现过热问题，因此控制电机退出堵转。
开启冷凝器对车辆的内部进行加热可以为电动压缩机开启，冷凝风扇开启，并打开冷凝器与车辆内部连通的风门。其中，在本申请实施例中，根据环境温度和车内温度，对车辆的内部进行加热，包括：
当环境温度处于第二预设温度和第三预设温度之间、且车辆的内部温度低于第二预设温度时，开启加热器和冷凝器，对车辆内部进行加热，其中，第二预设温度高于第三预设温度。
其中，第三预设温度可以为-20℃，第二预设温度可以为-10℃。S103、当环境温度或车内温度高于第二预设温度时，对车辆内的驾驶舱进行余热回收，以对车辆进行热管理。
其中，第二预设温度可以为适应热泵中各设备使用的温度。在本申请实施例中，第二预设温度可以为-10℃。其中，当环境温度或车内温度高于第二预设温度时，对车辆内的驾驶舱进行余热回收，以对车辆进行热管理可以为打开蒸发风机，关闭外循环，然后开启蒸发器工作，吸收来自驾驶舱的热量，进行驾驶舱的余热回收。
其中，在本申请实施例中，当环境温度或车内温度高于第二预设温度时，对车辆内的驾驶舱进行余热回收，以对车辆进行热管理可以包括：
当环境温度和车内温度高于第二预设温度时，关闭车辆的外循环；
在关闭外循环后，启动蒸发器对车辆内的驾驶舱进行余热回收，以对车辆进行热管理。
其中，外循环可以是指在车辆空调系统中，通过控制空气进出口的开关，将车外的新鲜空气引入车内，同时将车内的空气排出车外，以保持车内空气的新鲜和舒适。
蒸发器可以用于将制冷剂从液态转化为气态，吸收车内的热量，从而使车内温度降低。同时，蒸发器还可以用于余热回收，即将车内的余热通过蒸发器传递到热泵中，从而使得热泵对车辆进行热管理。
其中，在本申请实施例中，在关闭外循环，启动蒸发器对车辆内的驾驶舱进行余热回收之后，方法还包括：
获取蒸发器的出口温度、以及车辆的当前环境温度；
比对出口温度和当前环境温度；
若出口温度大于当前环境温度，则控制蒸发器向车辆的内部传输驾驶舱的余热，以对车辆进行热管理；
若出口温度小于当前环境温度时，则控制蒸发器将驾驶舱的余热排出至车辆外。
其中，控制蒸发器向车辆内部传输热量可以指将驾驶舱余热进行回收利用的过程。
控制蒸发器向车辆外部排出热量可以指驾驶舱的热量较高，使得出口温度大于当前环境温度，故可以将驾驶舱余热进行回收利用的过程，在将驾驶舱余热回收以后，可以对车辆进行热管理。控制蒸发器向车辆外部排出热量可以指驾驶舱的热量较低，不足以进行回收，故控制蒸发器向车辆外部排出热量。
本申请实施例提供的车辆控制方法，可以根据环境温度和车内温度，对驾驶舱进行余热回收，由此，可以充分利用驾驶室废热，提高热管理效率。同时，通过第一预设温度、第二预设温度和第三预设温度的设置，并通过对应的预加热和加热方式，从而可以增加热泵的使用范围，降低在极寒天气内的制热电量消耗。

S204、当环境温度低于零下20摄氏度，且车内温度低于零下10摄氏度时，控制车辆处于超低温制热模式。
其中，控制车辆处于超低温制热模式可以为：HVCH开启制热，加热水路中的冷却液，热量通过chiller(电池冷却器)加热空调中的冷媒温度，同时开启电机堵转发热能耗，快速提升冷却液的温度；其中，当冷却液的温度高于-20℃时，电机堵转发热退出，电动压缩机开启，冷凝风扇开启，控制风道管路的风门1和风门6关闭，风门2打开，以使冷凝器向车辆内部放热实现制热功能，由此，加热车辆内部。
S205、当整车控制器检查到的车内温度升高至零下10摄氏度以上时，车辆由超低温制热模式切换为驾驶舱余热回收制热模式一。
其中，控制车辆处于驾驶舱余热回收制热模式一可以为：蒸发风机开启，整车控制器控制风门5关闭外循环，整车控制器开启蒸发器工作，吸收来自驾驶舱的热量，进行驾驶舱废热回收，同时整车控制器根据预设的算法降低HVCH的功率，其中，当蒸发器出口风温大于环境温度时，整车控制器控制风道管路的风门3和风门4关闭，风门6打开，由此，对车辆进行热管理，当蒸发器出口温度小于环境温度时，整车控制器控制风道管路的风门3和风门6关闭，风门4打开，由此，将回收的热量排出至车辆外。
S206、当环境温度处于零下20摄氏度和零下10摄氏度之间，且车内温度低于零下10摄氏度时，控制车辆处于低温制热模式。
其中，控制车辆处于低温制热模式可以为：控制加热器工作，且加热器功率随着车内温度的升高降低，电动压缩机开启，冷凝风扇开启，风门1和风门6关闭，风门2打开，冷凝器放热实现制热功能，由此，使得车内随着时间的推移温度不断升高。
S207、当整车控制器检查到的车内温度升高至零下10摄氏度以上时，车辆由超低温制热模式切换为驾驶舱余热回收制热模式一；
S208、当环境温度低于零下20摄氏度，且车内温度高于零下10摄氏 度时、当环境温度在零下20摄氏度和零下10摄氏度之间，且车内温度高于零下10摄氏度时、当环境温度在零下10摄氏度～N摄氏度时，控制车辆处于驾驶舱余热回收制热模式二。
其中，控制车辆处于驾驶舱余热回收制热模式二可以为：电动压缩机开启，冷凝风扇开启，控制风道管路的风门1关闭，风门2打开，使得蒸发器与座舱连通，蒸发风机打开，算法控制风门5关闭外循环，整车控制器开启蒸发器工作，吸收来自驾驶舱的热量，进行驾驶舱废热回收，当蒸发器出口风温大于环境温度时，整车控制器控制风门3和风门4关闭，风门6打开，当蒸发器出口温度小于环境温度时，整车控制器控制风门3和风门6关闭，风门4打开，同时降低HVCH(加热器)的功率。
其中，N℃可以指车辆内的处于设置的正常温度。
S209、当环境温度在高于等于N℃，AUTO处于非制热状态。
