  • Fasteners They can also be called standard fasteners or standard parts. They are a general term for a type of mechanical parts used to fasten two or more parts (or components) into a whole. Fasteners come in a wide variety of specifications, with different performances and uses, and are highly standardized, serialized, and universal.
  • Fasteners include but are not limited to the following types of parts:
  • Bolt A type of fastener that includes a head and a screw (a cylinder with external threads). It must be used in conjunction with a nut to fasten two parts with through holes. This type of connection is called a bolt connection. Unscrewing the nut from the bolt can separate the two parts, so a bolt connection is a detachable connection.
  • Stud Unlike bolts, studs have no head and are a type of fastener with external threads on both ends. When connecting, one end must be screwed into a part with an internal threaded hole, and the other end must pass through a part with a through hole, and then a nut is screwed on to fasten the two parts into a whole.
  • This type of connection is called a stud connection, which is also a detachable connection. It is mainly used in scenarios where one of the connected parts is thicker, requires a compact structure, or is frequently disassembled and bolt connections are not suitable.
  • Screw A type of fastener that includes a head and a screw. It can be divided into three categories according to its use: machine screws, set screws, and special-purpose screws. It can be used with or without a nut. For example, when it is used to fasten a part with a set threaded hole to a part with a through hole, it does not need to be used with a nut; when it is used to fasten two parts with through holes, it needs to be used with a nut. This type of connection is called a screw connection, which is also a detachable connection.
  • Self-tapping screws Also known as quick-thread screws, they are steel fasteners that have been galvanized and passivated. Self-tapping screws are mostly used to connect thin metal plates (such as steel plates, sawn plates, etc.). When connecting, it is necessary to first make a threaded bottom hole for the connected parts, and then screw the self-tapping screw into the threaded bottom hole of the connected parts.
  • Wood screws Similar to machine screws, but the threads on the screw are special wood screw threads that can be screwed directly into wooden components (or parts) to fasten a metal (or non-metal) part with a through hole to a wooden component. This type of connection is a detachable connection.
  • Rivet A type of fastener that includes a head and a shank, used to fasten two parts (or components) with holes to make them a whole. This type of connection is called rivet connection, or riveting for short, and is a non-detachable connection. If you want to separate two parts connected by rivets, you need to break the rivets on the parts.
  • Welding nail It is the abbreviation of cylindrical head welding nail for arc stud welding.
  • Welding nail is a fastener with high strength and rigidity connection. It may include a nail rod and a nail head, or it may not include a nail head.
  • the welding nail is fixedly connected to a part (or component) by welding so as to connect it with other parts.
  • Pin Mainly used for positioning parts. Some pins can also be used to connect parts, fix parts, transmit power or lock fasteners, etc.
  • Nut A nut with an internal threaded hole. Its shape includes but is not limited to a flat hexagonal column, a flat square column or a flat cylindrical column. It is used with bolts, studs or screws to fasten two parts together to form a whole.
  • Washer A type of fastener whose shape includes but is not limited to an oblate ring. It can be placed between the support surface of a bolt, screw or nut and the surface of the connected part to increase the contact surface area of the connected parts, reduce the pressure per unit area and protect the surface of the connected parts from damage. Another type is an elastic washer, which can also prevent the nut from loosening.
  • Retaining ring It is installed in the shaft groove or shaft hole groove of the machine or equipment to prevent the parts on the shaft or hole from moving left and right.
  • the currently known design solutions include the following two: the first is that the ECU can have its own liquid cooling structure (for the convenience of description, this ECU is referred to as an ECU with a self-contained liquid cooling structure in this application), and the ECU with a self-contained liquid cooling structure can be directly connected to the vehicle's thermal management device for cooling and heat dissipation; the second is to install an independent liquid cooling plate externally, fix the ECU without a liquid cooling structure (for the convenience of description, this ECU is referred to as an ECU without a self-contained liquid cooling structure in this application) on the liquid cooling plate, and the liquid cooling plate is connected to the vehicle's thermal management device to cool and dissipate the non-self-contained liquid cooling structure ECU fixed on the liquid cooling plate.
  • the vehicle may include both ECUs without self-liquid cooling and ECUs with self-liquid cooling.
  • Some ECUs without self-liquid cooling with low power consumption do not generate much heat, and can ensure that they work in a suitable temperature environment through their own heat dissipation; while some ECUs without self-liquid cooling with high power consumption generate relatively high heat, and cannot ensure that they work in a suitable temperature environment only through their own heat dissipation. Therefore, these ECUs without self-liquid cooling with high power consumption also need to be connected to thermal management devices to ensure that they work in a suitable temperature environment.
  • FIG. 1 is a schematic diagram of a thermal management system. As shown in Figure 1, an ECU with a liquid cooling structure can be directly connected to the thermal management device of the vehicle and become a part of the thermal management system of the vehicle; while an ECU without a liquid cooling structure needs to be fixed on an independent liquid cooling plate and then connected to the thermal management device of the vehicle and become a part of the thermal management system.
  • the liquid cooling plate on which the ECU without a liquid cooling structure is fixed needs to be connected to the water circuit of the thermal management system, and the ECU with a liquid cooling structure also needs to be connected to the water circuit of the thermal management system, which makes the water circuit connection of the thermal management system very complicated; in addition, both the ECU without a liquid cooling structure and the ECU with a liquid cooling structure need to communicate with the thermal management device in the thermal management system, which makes the communication connection of the thermal management system very complicated and the system maintenance is also difficult.
  • the embodiments of the present application provide an electronic control unit, a control system and a terminal.

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
为便于清楚描述本申请实施例的技术方案，首先做出如下说明。
第一，在本申请实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。例如，第一ECU、第二ECU是为了区分不同的ECU，并不对其先后顺序进行限定。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
第二，在本申请实施例中，“至少一种(个)”是指一种(个)或者多种(个)。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系，但并不排除表示前 后关联对象是一种“和”的关系的情况，具体表示的含义可以结合上下文进行理解。
第三，在本申请实施例中，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、***、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
首先对本申请中涉及到的术语作简单说明。
1、ECU：又称“行车电脑”、“车载电脑”等。ECU与普通的电脑一样，由微控制器(microcontroller unit，MCU)、存储器、输入/输出接口、模数转换器以及整形、驱动等大规模集成电路组成。ECU的正常工作温度在-40摄氏度(degree Celsius，℃)至80℃。
2、CAN总线：车内通信链路的一个示例。CAN总线是一种有效支持分布式控制或实时控制的串行通信网络。CAN总线用于车辆的部件之间的连接，例如，CAN总线可以连接包括CAN控制器芯片、数据接收器和数据发送器等在内的部件。
3、紧固件(fastener)：也可以称为标准紧固件或标准件。是将两个或两个以上零件(或构件)紧固连接成为一件整体时所采用的一类机械零件的总称。紧固件的品种规格繁多，性能用途各异，而且标准化、系列化、通用化的程度极高。
紧固件包括但不限定于以下几类零件：
螺栓：包括头部和螺杆(带有外螺纹的圆柱体)的一类紧固件，需与螺母配合，用于紧固连接两个带有通孔的零件。这种连接形式称螺栓连接。把螺母从螺栓上旋下，可以使这两个零件分开，所以螺栓连接是属于可拆卸连接。
螺柱：不同于螺栓，螺柱没有头部，是两端均外带螺纹的一类紧固件。连接时，它的一端必须旋入带有内螺纹孔的零件中，另一端穿过带有通孔的零件中，然后旋上螺母，以使得这两个零件紧固连接成一件整体，这种连接形式称为螺柱连接，也是属于可拆卸连接。主要用于被连接零件之一厚度较大、要求结构紧凑，或因拆卸频繁，不宜采用螺栓连接的场景。
螺钉：包括头部和螺杆的一类紧固件，按用途可以分为三类：机器螺钉、紧定螺钉和特殊用途螺钉。可以与螺母配合，也可以不与螺母配合，例如，在用于一个紧定螺纹孔的零件与一个带有通孔的零件之间的紧固连接的情况下，不需要与螺母配合；用于两个带有通孔的零件之间的紧固连接的情况下，需要与螺母配合。这种连接形式称为螺钉连接，也属于可拆卸连接。
自攻螺钉：又称快牙螺丝，是钢制经表面镀锌钝化的快装紧固件。自攻螺钉多用于薄的金属板(例如钢板、锯板等)之间的连接。连接时，需要先对被连接件制出螺纹底孔，再将自攻螺钉拧入被连接件的螺纹底孔中。
木螺钉：与机器螺钉相似，但螺杆上的螺纹为专用的木螺钉专用螺纹，可以直接旋入木质构件(或零件)中，用于把一个带通孔的金属(或非金属)零件与一个木质构件紧固连接在一起。这种连接属于可拆卸连接。
铆钉：包括头部和钉杆的一类紧固件，用于紧固连接两个带孔的零件(或构件)，使之成为一件整体。这种连接形式称为铆钉连接，简称铆接，属于不可拆卸连接。如果想要使得用铆钉连接在一起的两个零件分开，需要破坏零件上的铆钉。
焊钉：是电弧螺柱焊用圆柱头焊钉的简称，焊钉是一种高强度刚度连接的紧固件，可以包括钉杆和钉头，或者也可以不包括钉头，用焊接方法把焊钉固定连接在一个零件(或构件)上面，以便再与其他零件进行连接。
销：主要供零件定位，有的销也可以用于零件连接、固定零件、传递动力或锁定紧固件等。
另外，在实际应用场景中，上述螺栓、螺柱或螺钉等可以配合螺母、垫圈、挡圈等使用，本申请实施例对此不作任何限定。
螺母：带有内螺纹孔，形状包括但不限于扁六角柱形、扁方柱形或扁圆柱形，配合螺栓、螺柱或螺钉等，用于紧固连接两个零件，使之成为一个整体。
垫圈：形状包括但不限于呈扁圆环形的一类紧固件。可以置于螺栓、螺钉或螺母的支撑面与连接零件表面之间，起到增大被连接零件接触表面面积，降低单位面积压力和保护被连接零件表面不被损坏的作用。还有一类是弹性垫圈，还能起到阻止螺母回松的作用。
挡圈：供装在机器、设备的轴槽或轴孔槽中，起到阻止轴上或孔上的零件左右移动的作用。
随着车辆的智能化，车载ECU的数量急剧增加，ECU的功耗也明显增加。对于一些功耗较高的需要主动散热的ECU，目前已知的设计方案包括以下两种：第一种，ECU可以自带液冷结构(为了便于描述，本申请中将这种ECU记为简称自带液冷结构的ECU)，自带液冷结构的ECU可以直接连接到车辆的热管理装置，进行降温散热；第二种，外置一个独立的液冷板，将没有液冷结构的ECU(为了便于描述，本申请中将这种ECU记为简称非自带液冷结构的ECU)固定在该液冷板上，该液冷板连接到车辆的热管理装置，对固定在该液冷板上的非自带液冷结构ECU进行降温散热。
也就是说，车辆上可以包括非自带液冷结构的ECU和自带液冷结构的ECU。一些功耗较小的非自带液冷结构的ECU产生的热量并不高，通过其自身的散热就可以保证其自身工作在合适的温度环境中；而一些功耗较高的非自带液冷结构的ECU产生的热量比较高，仅通过其自身的散热无法保证其自身工作在合适的温度环境中，因此，这些功耗较高的非自带液冷结构的ECU也需要连接热管理装置，以保证其工作在合适的温度环境中。
图1是一种热管理***的示意图。如图1所示，自带液冷结构的ECU可以直接连接到整车的热管理装置，成为车辆的热管理***中的一部分；而在非自带液冷结构的ECU需要固定在独立的液冷板上，再连接到整车的热管理装置，成为热管理***中的一部分。在非自带液冷结构的ECU和自带液冷结构的ECU的数量较多的情况下，非自带液冷结构的ECU所固定在的液冷板需要接入热管理***的水路中，自带液冷结构的ECU也需要接入热管理***的水路中，从而导致热管理***的水路连接很复杂；另外，非自带液冷结构的ECU和自带液冷结构的ECU均需要与热管理***中的热管理装置进行通信，从而导致热管理***的通信连接也很复杂，***维护也比较困难。
针对上述问题，本申请实施例提供了电子控制单元、控制***和终端，通过在非自带液冷结构的ECU和自带液冷结构的ECU上设置紧固接口，并基于紧固接口将非自带液冷结构的ECU和自带液冷结构的ECU紧固连接在一起，以此来复用自带液冷 结构的ECU的液冷结构，不需要增加额外的独立的液冷板，只需要将自带液冷结构的ECU连接到热管理***的水路中即可，在热管理***的水路中减少了额外的独立的液冷板的接入，可以降低热管理***的复杂度，进而降低***维护的难度。另外，不需要再额外采购独立的液冷板，可以降低成本。
以下先结合图2至图4对本申请提供的第一ECU和第二ECU进行详细说明。
图2是本申请实施例提供的一种第一ECU的示意图。
本申请实施例提供了一种第一ECU，第一ECU包括液冷结构，且该第一ECU包括至少两个紧固接口用于安装紧固件，紧固件用于紧固连接该第一ECU与不包括液冷结构的第二ECU。
上文已述及，紧固件是将两个或两个以上零件(或构件)紧固连接成为一件整体时所采用的一类机械零件的总称，紧固件的品种规格繁多，性能用途各异，而且标准化、系列化、通用化的程度极高。在实际应用场景中，紧固接口可以根据不同的需求来进行设置，紧固接口的具体形态与紧固件向对应，适用于不同类型的紧固件的紧固接口的形态可以不同，本申请实施例对此不作任何限定。
示例性地，如图2所示，图2的a)示出了一种第一ECU的三维立体图，图2的b)示出了图2的a)中第一ECU的俯视图，该第一ECU包括液冷结构210和多个紧固接口，例如紧固接口221、紧固接口222、紧固接口223、紧固接口224、紧固接口225和紧固接口226。
在第一ECU所包括的紧固接口中有至少两个紧固接口与第二ECU所包括的紧固接口中的至少两个紧固接口是可以对齐的，以便于将第二ECU紧固连接在第一ECU上。
作为示例而非限定，如图2的b)所示，紧固接口221、紧固接口224和紧固接口225所在的位置可以连成一条直线，也就是说，紧固接口221、紧固接口224和紧固接口225所在的位置在同一条直线上，紧固接口222、紧固接口223和紧固接口226所在的位置无法连成一条直线，也就是说，紧固接口222、紧固接口223和紧固接口226所在的位置不在同一条直线上。这样一来，可以通过紧固接口221、紧固接口222、紧固接口223、紧固接口224、紧固接口225和紧固接口226将不同尺寸的第二ECU与该第一ECU紧固连接在一起，具有较好的普适性。
以下结合图3对可以适配于本申请实施例提供的第一ECU的第二ECU的不同尺寸进行说明。
图3是本申请实施例提供的适配于第一ECU的第二ECU的不同尺寸的对比图。
示例一，如图3的a)，可以通过紧固接口221和紧固接口223，或者，紧固接口222和紧固接口224，或者，紧固接口221、紧固接口222和紧固接口223，或者，紧固接口221、紧固接口222和紧固接口224，或者，紧固接口222、紧固接口223和紧固接口224，或者，紧固接口221、紧固接口224和紧固接口223，或者，紧固接口221、紧固接口222、紧固接口223和紧固接口224，将大小为尺寸1的第二ECU与该第一ECU紧固连接在一起。
示例二，如图3的b)，可以通过紧固接口223和紧固接口225，或者，紧固接口221和紧固接口226，或者，紧固接口221、紧固接口222和紧固接口226，或者，紧固接口 223、紧固接口224和紧固接口225，将大小为尺寸2的第二ECU与该第一ECU紧固连接在一起。
可以理解的是，可以将一个大小为尺寸1的第二ECU紧固连接在一个第一ECU上，也可以将一个或两个大小为尺寸2的第二ECU紧固连接在一个第一ECU上；本申请实施例对此不作任何限定。
应理解，上述尺寸1和尺寸2并非严格意义上的大小尺寸，只是为了区分不同尺寸(或者规格)的第二ECU，不应对本申请产生任何限定。
图2和图3仅为示例，在实际应用场景中，第一ECU可以包括更多或更少的紧固接口，只要保证第二ECU能够紧固连接在第一ECU上即可，本申请实施例对第一ECU包括的紧固接口的具体数量不作限定。
可选地，第一ECU的液冷结构包括：用于盛放冷却液的腔体，以及连接于该腔体的进液口和出液口，该液冷结构与所述第一电子控制单元一体成型。
作为示例而非限定，如图2所示，第一ECU的液冷结构210可以包括腔体211、进液口212和出液口213，液冷液可以从进液口212进入到腔体211，再从出液口213流出到腔体211以外。该液冷结构210与该第一ECU一体成型，也就是说，该液冷结构210是该第一ECU的不可拆卸的一部分。
在一种可能的设计中，该第一ECU还包括至少一个导热槽，导热槽位于腔体的外表面，导热槽用于盛放导热材料，导热材料用于导热。
作为示例而非限定，如图2所示，第一ECU还可以包括导热槽231和导热槽232。在利用紧固件将第一ECU和第二ECU紧固连接在一起之前，可以在导热槽中放置导热材料，以便于第一ECU和第二ECU之间更好的导热。导热材料包括但不限于导热垫、导热凝胶等，本申请实施例对此不作任何限定。
在一种可能的设计中，该第一ECU用于获取第二ECU的温度。
第一ECU可以获取自身的温度，第二ECU也可以获取自身的温度。第一ECU与第二ECU可以进行通信，第一ECU可以从第二ECU获取到第二ECU的温度，以便于基于第一ECU的温度和第二ECU的温度进行后续的处理。
紧固连接在一起的非自带液冷结构的ECU和自带液冷结构的ECU可以看作一个整体，且第一ECU与第二ECU之间可以基于通信通道进行内部通信(例如第一ECU获取第二ECU的温度)，基于此，第一ECU与热管理装置进行通信连接即可，第二ECU不需要与热管理装置进行通信连接，可以在一定程度上降低热管理***的通信连接的复杂度，进一步降低***维护的难度。
基于上述方案，通过在自带液冷结构的ECU上设置紧固接口，并基于紧固接口将非自带液冷结构的ECU和自带液冷结构的ECU紧固连接在一起，也即，紧固连接在一起的非自带液冷结构的ECU和自带液冷结构的ECU可以看作一个整体，以此来复用自带液冷结构的ECU的液冷结构，不需要增加额外的独立的液冷板，只需要将自带液冷结构的ECU连接到热管理***的水路中即可，在热管理***的水路中减少了额外的独立的液冷板的接入，可以降低热管理***的复杂度。再者，紧固连接在一起的非自带液冷结构的ECU和自带液冷结构的ECU可以看作一个整体，且第一ECU与第二ECU之间可以基于通信通道进行内部通信，基于此，第一ECU与热管理装置进行通 信连接即可，第二ECU不需要与热管理装置进行通信连接，可以在一定程度上降低热管理***的通信连接的复杂度，进一步降低***维护的难度。并且，在降低热管理***的水路连接和通信连接的复杂度的情况下，对于整车而言，热管理***可以节省一定的空间占用。另外，不需要再额外采购独立的液冷板，可以降低成本。
图4是本申请实施例提供的一种第二ECU的示意图。
本申请实施例提供了一种第二ECU，第二ECU不包括液冷结构，该第二ECU包括至少两个紧固接口用于安装紧固件，紧固件用于紧固连接该第二ECU与包括液冷结构的第一ECU。

示例性地，如图4所示，图4的a)示出了一种第二ECU的三维立体图，图4的b)示出了图4的a)中第二ECU的仰视图，该第二ECU包括多个紧固接口，例如紧固接口401、紧固接口402、紧固接口403和紧固接口404。
在第二ECU所包括的紧固接口中有至少两个紧固接口与第一ECU所包括的紧固接口中的至少两个紧固接口是可以对齐的，以便于第二ECU能够紧固连接在第一ECU上。
上文已述及，可以将不同尺寸的第二ECU与本申请实施例提供的第一ECU紧固连接在一起，也即，在实际应用场景中，可以包括不同尺寸的第二ECU。

以下结合图5对本申请提供的控制***进行详细说明。
本申请还提供了一种控制***，该***包括第一ECU和第二ECU，该第一ECU包括液冷结构，该第二ECU不包括液冷结构；其中，该第一ECU和该第二ECU均包括至少两个紧固接口，这至少两个紧固接口用于安装紧固件，紧固件用于紧固连接该第一ECU和该第二ECU。
可以理解的是，一个第一ECU的液冷结构所在的这一面上可以紧固连接一个或多个第二ECU，本申请实施例对此不作任何限定。
图5是本申请实施例提供的一种控制***的示意图。如图5所示，该***包括第一ECU501、第二ECU 502、第一ECU 503、第二ECU 504和第二ECU 505，其中，第一ECU 501与第二ECU 502可以通过紧固接口紧固连接在一起，第一ECU 503与第二ECU 504和第二ECU 505可以通过紧固接口紧固连接在一起。
作为示例而非限定，第二ECU 502的尺寸可以是上文中所述的尺寸1，第二ECU 504和第二ECU 505的尺寸可以是上文中所述的尺寸2，本申请实施例对此不作任何限定。
一示例性，例如，第一ECU 501和第一ECU 503可以包括如图2所示的紧固接口221、紧固接口222、紧固接口223、紧固接口224、紧固接口225和紧固接口226。

在一种可能的实现方式中，第一ECU用于基于通信通道从第二ECU获取该第二ECU的温度。
上文已述及，第一ECU可以获取自身的温度，第二ECU也可以获取自身的温度。第一ECU与第二ECU可以基于上述通信通道进行通信，从而，第一ECU可以从第二ECU获取到第二ECU的温度，以便于基于第一ECU的温度和第二ECU的温度进行后续的处理。
紧固连接在一起的非自带液冷结构的ECU和自带液冷结构的ECU可以看作一个整体，且第一ECU与第二ECU之间可以基于通信通道进行内部通信(例如第一ECU获取第二ECU的温度)，基于此，第一ECU与热管理装置进行通信连接即可，第二ECU不需要与热管理装置进行内部通信连接。如图5所示，第一ECU 501可以获取自身的温度，并基于与第二ECU 502之间的通信通道从第二ECU 502获取该第二ECU 502的温度；第一ECU 503可以获取自身的温度，并基于与第二ECU 504之间的通信通道从第二ECU 504获取该第二ECU 504的温度，以及，基于与第二ECU 505之间的通信通道从第二ECU 505获取该第二ECU 505的温度。继而，第一ECU 501和第一ECU 503再与热管理装置进行通信，不需要第二ECU 502、第二ECU 504和第二ECU 505与热管理装置之间进行通信，从而可以在一定程度上降低热管理***的通信连接的复杂度，进一步降低***维护的难度。
可选地，该控制***还包括热管理装置，第一ECU的液冷结构连接该热管理装置，该热管理装置用于控制流出该热管理装置的冷却液的目标温度和/或目标流速。

应理解，图5仅为一示例，在实际应用场景中，控制***可以包括更多或更少的第一ECU，也可以包括更多或更少的第二ECU，本申请实施例对此不作任何限定。
虽然图5中未示出，热管理装置也可以包括进液口和出液口。例如，第一ECU 501和第一ECU 503的液冷结构的进液口可以连接热管理装置510的出液口，第一ECU 501和第一ECU 503的液冷结构的出液口可以连接热管理装置510的进液口，从而实现冷却液在热管理装置与第一ECU的液冷结构之间的循环流动，以保证该控制***中的第一ECU和第二ECU工作在合适的温度环境中。
可以理解的是，包括热管理装置的控制***也就是上文所述及到的热管理***(TMS)。
在一种可能的实现方式中，第一ECU还用于根据该第一ECU的温度和第二ECU的温度向热管理装置上报对冷却液的需求温度和/或需求流速的指示信息；热管理装置具体用于：接收多个第一ECU上报的指示信息；根据所接收的多个指示信息，控制目 标温度和/或目标流速。
其中，指示信息可以包括需求温度和/或需求流速，也可以不包括需求温度和/或需求流速，本申请实施例对该指示信息包括的具体内容不作限定，只要基于该指示信息可以获知需求温度和/或需求流速即可。
示例性地，第一ECU在获取到自身的温度，以及获取到第二ECU的温度后，第一ECU可以根据自身的温度和第二ECU的温度，来确定对液冷液的需求温度和/或需求流速，可以生成对冷却液的需求温度和/或需求流速的指示信息，并可以将该指示信息上报给热管理装置。
例如，第一ECU 501在获取自身的温度，以及获取到第二ECU 502的温度后，可以根据自身的温度和第二ECU 502的温度，来确定第一ECU 501和第二ECU 502对液冷液的需求温度和/或需求流速，可以生成对冷却液的需求温度和/或需求流速的指示信息，并可以将该指示信息上报给热管理装置。
又例如，第一ECU 503在获取自身的温度，以及获取到第二ECU 504和第二ECU505的温度后，可以根据自身的温度和第二ECU 504和第二ECU 505的温度，来确定第一ECU 501、第二ECU 504和第二ECU 505对液冷液的需求温度和/或需求流速，可以生成对冷却液的需求温度和/或需求流速的指示信息，并可以将该指示信息上报给热管理装置。
相应地，热管理装置可以接收多个第一ECU上报的指示信息，并根据所接收到的多个指示信息，来控制流出该热管理装置的冷却液的目标温度和/或目标流速。例如，热管理装置510可以接收第一ECU 501和第一ECU 503上报的指示信息，并根据第一ECU 501和第一ECU 503上报的指示信息，来确定出目标温度和/或目标流速，并基于目标温度和/或目标流速对冷却液流出该热管理装置时的温度和/或速度进行控制。
作为示例而非限定，热管理装置可以根据接收到的多个指示信息确定多个需求温度和/或需求流速，继而可以将多个需求温度中数值最小的温度确定为流出该热管理装置的冷却液的目标温度，和/或，将多个需求流速中数值最大的流速确定为流出该热管理装置的冷却液的目标流度。本申请实施例对此不作任何限定。
可以理解的是，在第二ECU紧固连接在第一ECU上的情况下，第一ECU可以基于第一ECU的温度和第二ECU的温度来确定对液冷液的需求温度和/或需求流速，进而生成对冷却液的需求温度和/或需求流速的指示信息；在第一ECU没有紧固连接第二ECU的情况下，第一ECU可以基于第一ECU自身的温度来确定对液冷液的需求温度和/或需求流速，进而生成对冷却液的需求温度和/或需求流速的指示信息。本申请实施例对此不作限定。
在另一种可能的实现方式中，第一ECU还用于向热管理装置上报该第一ECU的温度和第二ECU的温度；该热管理装置具体用于：接收多个第一ECU上报的温度；根据所接收的多个温度，控制目标温度和/或目标流速。
示例性地，第一ECU在获取到自身的温度，以及获取到第二ECU的温度后，可以将自身的温度和第二ECU的温度上报给热管理装置。
例如，第一ECU 501在获取自身的温度，以及获取到第二ECU 502的温度后，可以将自身的温度和第二ECU 502的温度上报给热管理装置。
又例如，第一ECU 503在获取自身的温度，以及获取到第二ECU 504和第二ECU505的温度后，可以将自身的温度和第二ECU 504和第二ECU 505的温度上报给热管理装置。
相应地，热管理装置可以接收多个第一ECU上报的温度，并根据所接收到的温度来控制流出该热管理装置的冷却液的目标温度和/或目标流速。例如，热管理装置510可以接收第一ECU 501上报的第一ECU 501和第一ECU 503的温度，以及接收第一ECU503上报的第一ECU 503、第二ECU 504和第二ECU 505的温度，并根据这些温度，来确定出目标温度和/或目标流速，并基于目标温度和/或目标流速对冷却液流出该热管理装置时的温度和/或速度进行控制。
作为示例而非限定，热管理装置可以根据接收到的这多个温度中数值最大的温度来控制流出该热管理装置的冷却液的目标温度和/或目标流速。本申请实施例对此不作任何限定。
应理解，热管理装置可以包括处理器和接收单元，接收单元可以用于接收多个第一ECU上报的指示信息或温度，处理器可以用于基于接收单元所接收到的指示信息或温度来控制流出该热管理装置的冷却液的目标温度和/或目标流速。另外，该热管理装置还可以包括存储器，存储器可以用于保存程序指令和/或数据，存储器可以位于处理器之内或处理器之外，本申请实施例对此不作任何限定。
可以理解的是，在第二ECU紧固连接在第一ECU上的情况下，第一ECU可以将自身的温度和第二ECU的温度上报给热管理装置；在第一ECU没有紧固连接第二ECU的情况下，第一ECU可以将自身的温度上报给热管理装置。本申请实施例对此不作限定。
基于上述方案，通过在非自带液冷结构的ECU和自带液冷结构的ECU上设置紧固接口，并基于紧固接口将非自带液冷结构的ECU和自带液冷结构的ECU紧固连接在一起，也即，紧固连接在一起的非自带液冷结构的ECU和自带液冷结构的ECU可以看作一个整体，以此来复用自带液冷结构的ECU的液冷结构，不需要增加额外的独立的液冷板，只需要将自带液冷结构的ECU连接到热管理***的水路中即可，在热管理***的水路中减少了额外的独立的液冷板的接入，可以降低热管理***的复杂度。再者，紧固连接在一起的非自带液冷结构的ECU和自带液冷结构的ECU可以看作一个整体，且第一ECU与第二ECU之间可以基于通信通道进行内部通信，基于此，第一ECU与热管理装置进行通信连接即可，第二ECU不需要与热管理装置进行通信连接，可以在一定程度上降低热管理***的通信连接的复杂度，进一步降低***维护的难度。并且，在降低热管理***的水路连接和通信连接的复杂度的情况下，对于整车而言，热管理***可以节省一定的空间占用。另外，不需要再额外采购独立的液冷板，可以降低成本。
本申请实施例还提供一种终端，该终端包括上文所述的控制***。
可选地，该终端可以包括车辆。
