Description

Electronic control units, control systems and terminals Technical Field

[0001] The present application relates to the automotive field, and in particular to an electronic control unit, a control system, and a terminal. Background Art

[0002] An electronic control unit (ECU), also known as a "driving computer" or "onboard computer," is a terminal microcomputer controller. In the vehicle domain, it can also be called a dedicated single-chip microcomputer. Some ECUs can be connected to a thermal management device, forming a thermal management system (TMS) to ensure that the ECU operates in an appropriate temperature environment.

[0003] As vehicles become increasingly intelligent, the number of onboard ECUs has increased dramatically, leading to a significant increase in ECU power consumption. For high-power ECUs requiring active cooling, currently known design solutions include: The ECU can have a built-in liquid cooling mechanism connected to the vehicle's thermal management system for cooling and dissipation; or an external, independent liquid cooling plate is mounted on the ECU, which is then connected to the vehicle's thermal management system to cool and dissipate heat for the attached ECU. However, if there are a large number of both non- and built-in liquid cooling ECUs, the thermal management system's water connections can become complex, making system maintenance more difficult.

[0004] Summary of the Invention

[0005] The present application provides an electronic control unit, a control system, and a terminal in order to reduce the complexity of the thermal management system and thereby reduce the difficulty of system maintenance.

[0006] In a first aspect, the present application provides a control system comprising a first ECU and a second ECU, wherein the first ECU comprises a liquid cooling structure, and the second ECU does not comprise a liquid cooling structure; wherein the first ECU and the second ECU each comprise at least two fastening interfaces, and the at least two fastening interfaces are used for installing fasteners, and the fasteners are used for fastening the first ECU and the second ECU.

[0007] Based on the above solution, by providing a fastening interface on the ECU without a self-liquid cooling structure and the ECU with a self-liquid cooling structure, and fastening the non-self-liquid cooling ECU and the ECU with a self-liquid cooling structure together based on the fastening interface, the liquid cooling structure of the ECU with a self-liquid cooling structure can be reused. There is no need to add an additional independent liquid cooling plate. Only the ECU with a self-liquid cooling structure needs to be connected to the water path of the thermal management system. This reduces the need for additional independent liquid cooling plates in the water path of the thermal management system, reduces the complexity of the thermal management system, and thus reduces the difficulty of system maintenance. In addition, there is no need to purchase additional independent liquid cooling plates, which can reduce costs.

[0008] Optionally, the liquid cooling structure of the first ECU includes: a cavity for containing cooling liquid, and a liquid inlet and a liquid outlet connected to the cavity, and the liquid cooling structure is integrally formed with the first ECU.

[0009] The liquid cooling structure is integrally formed with the first ECU, which can also be understood as the liquid cooling structure being a non-detachable part of the first ECU.

[0010] In combination with the first aspect, in some possible designs, the first ECU also includes at least one heat-conducting groove, which is located on the outer surface of the cavity and the opening of the heat-conducting groove faces the second ECU. The heat-conducting groove is used to hold heat-conducting material, and the heat-conducting material is used to conduct heat.

[0011] Thermally conductive materials include but are not limited to thermal pads, thermally conductive gels, etc., and this application does not impose any restrictions on this.

[0012] In combination with the first aspect, in some possible designs, the first ECU and the second ECU communicate based on a communication channel, which includes a controller area network (CAN) bus, a CAN-flexible data-rate (FD) bus, Ethernet or a wireless network.

[0013] The second ECU and the first ECU can communicate with each other through a CAN bus, a CAN-FD bus, an Ethernet or a wireless network. That is, the second ECU and the first ECU can be physically connected through a CAN bus or a CAN-FD bus, or can be physically connected through an Ethernet cable, or can be wirelessly connected through a wireless network. This application does not impose any restrictions on this.

[0014] In combination with the first aspect, in some possible designs, the first ECU is configured to obtain the temperature of the second ECU from the second ECU based on a communication channel.

[0015] The ECU without self-liquid cooling structure and the ECU with self-liquid cooling structure that are fastened together can be regarded as a whole, and the first ECU and the second ECU can communicate based on the communication channel. Based on this, the first ECU only needs to communicate with the thermal management device, and the second ECU does not need to communicate with the thermal management device internally. This can reduce the complexity of the communication connection of the thermal management system to a certain extent and further reduce the difficulty of system maintenance.

[0016] Optionally, the system further includes a thermal management device, to which the liquid cooling structure of the first ECU is connected, and the thermal management device is used to control a target temperature and / or a target flow rate of the coolant flowing out of the thermal management device.

[0017] The thermal management device may also include a liquid inlet and a liquid outlet. For example, the liquid inlet of the liquid cooling structure of the first ECU may be connected to the liquid outlet of the thermal management device, and the liquid outlet of the liquid cooling structure of the first ECU may be connected to the liquid inlet of the thermal management device, thereby realizing the circulation of the coolant between the thermal management device and the liquid cooling structure of the first ECU to ensure that the first ECU and the second ECU in the control system operate in a suitable temperature environment.

[0018] In combination with the first aspect, in some possible designs, the first ECU is also used to report indication information of the required coolant temperature and / or required flow rate to the thermal management device based on the temperature of the first ECU and the temperature of the second ECU; the thermal management device is specifically used to: receive indication information reported by multiple first ECUs; and control the target temperature and / or target flow rate based on the multiple indication information received.

[0019] In combination with the first aspect, in some possible designs, the first ECU is also used to report the temperature of the first ECU and the temperature of the second ECU to the thermal management device; the thermal management device is specifically used to: receive temperatures reported by multiple first ECUs; and control the target temperature and / or target flow rate based on the multiple temperatures received.

[0020] In a second aspect, the present application provides a first ECU, which includes a liquid cooling structure and at least two fastening interfaces for installing fasteners, and the fasteners are used to fasten the first ECU to a second ECU that does not include a liquid cooling structure.

[0021] Based on the above solution, by providing a fastening interface on the ECU with its own liquid cooling structure, and fastening the ECU without its own liquid cooling structure and the ECU with its own liquid cooling structure together based on the fastening interface, that is, the ECU without its own liquid cooling structure and the ECU with its own liquid cooling structure that are fastened together can be regarded as a whole, thereby reusing the liquid cooling structure of the ECU with its own liquid cooling structure. There is no need to add an additional independent liquid cooling plate. It is only necessary to connect the ECU with its own liquid cooling structure to the water path of the thermal management system. This reduces the need for additional independent liquid cooling plates to be connected to the water path of the thermal management system, which can reduce the complexity of the thermal management system. In addition, there is no need to purchase additional independent liquid cooling plates, which can reduce costs.

[0022] Optionally, the liquid cooling structure includes: a cavity for containing cooling liquid, and a liquid inlet and a liquid outlet connected to the cavity, and the liquid cooling structure is integrally formed with the first ECU.

[0023] In combination with the second aspect, in some possible designs, the first ECU further includes at least one heat-conducting groove, which is located on the outer surface of the cavity. The heat-conducting groove is used to hold a heat-conducting material, and the heat-conducting material is used to conduct heat.

[0024] In conjunction with the second aspect, in some possible designs, the first ECU is used to obtain the temperature of the second ECU.

[0025] In a third aspect, the present application provides a second ECU, which does not include a liquid cooling structure. The second ECU includes at least two fastening interfaces for installing fasteners, and the fasteners are used to fasten the second ECU to the first ECU including the liquid cooling structure.

[0026] Based on the above solution, by providing a fastening interface on the ECU without a self-contained liquid cooling structure, and fastening the non-liquid cooling structure ECU and the self-contained liquid cooling structure ECU together based on the fastening interface, that is, the fastened ECU without a self-contained liquid cooling structure and the self-contained liquid cooling structure ECU can be regarded as a whole, thereby reusing the liquid cooling structure of the ECU with a self-contained liquid cooling structure. There is no need to add an additional independent liquid cooling plate. It is only necessary to connect the ECU with the self-contained liquid cooling structure to the water path of the thermal management system. The connection of additional independent liquid cooling plates in the water path of the thermal management system is reduced, which can reduce the complexity of the thermal management system. In addition, there is no need to purchase additional independent liquid cooling plates, which can reduce costs.

[0027] In a fourth aspect, the present application provides a terminal, comprising the control system as in the first aspect or any one of the first aspects.

[0028] Optionally, the terminal comprises a vehicle.

[0029] It should be understood that the fourth aspect of the present application corresponds to the technical solutions of the first to third aspects of the present application, and the beneficial effects achieved by each aspect and the corresponding feasible implementation methods are similar and will not be repeated.

[0036] The technical solution in this application will be described below with reference to the accompanying drawings.

[0037] In order to clearly describe the technical solutions of the embodiments of the present application, the following explanation is first made.

[0038] First, in the embodiments of this application, terms such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. For example, "first ECU" and "second ECU" are used to distinguish different ECUs and do not define their order. Those skilled in the art will understand that terms such as "first" and "second" do not define the number or order of execution, and do not necessarily imply differences.

[0039] Second, in the embodiments of the present application, "at least one" refers to one or more. "And / or" describes the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship, but it does not exclude the situation where it indicates that the previous and next associated objects are in an "and" relationship. The specific meaning can be understood in conjunction with the context.

[0040] Third, in the embodiments of the present application, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or are inherent to these processes, methods, products or apparatuses.

[0041] First, a brief explanation of the terms involved in this application is given.

[0042] 1. ECU: Also known as the "driving computer" or "on-board computer," the ECU, like a regular computer, consists of a microcontroller unit (MCU), memory, input / output interfaces, analog-to-digital converters, and large-scale integrated circuits such as regulators and drivers. The ECU operates normally within a temperature range of -40°C to 80°C.

[0043] 2. CAN bus: An example of an in-vehicle communication link. The CAN bus is a serial communication network that effectively supports distributed control or real-time control. The CAN bus is used to connect components in a vehicle. For example, the CAN bus can connect components such as CAN controller chips, data receivers, and data transmitters.

[0044] 3. Fasteners: Also known as standard fasteners or standard parts, they are a general term for mechanical components used to fasten two or more parts (or components) together into a single unit. Fasteners come in a wide variety of sizes and specifications, with diverse performance and applications, and are highly standardized, serialized, and universally applicable.

[0045] Fasteners include but are not limited to the following types of parts:

[0046] Bolt: A fastener consisting of a head and a shank (a cylindrical body with external threads). It is used with a nut to securely connect two parts with through-holes. This type of connection is called a bolted connection. Unscrewing the nut from the bolt allows the two parts to separate, making bolted connections removable.

[0047] Studs: Unlike bolts, studs lack heads and are externally threaded at both ends. To connect, one end must be screwed into a part with an internal threaded hole, while the other end passes through a part with a through hole. A nut is then screwed in, securing the two parts together as a single piece. This type of connection is called a stud connection and is also considered a detachable connection. It's primarily used when one of the connected parts is thick, requires a compact structure, or requires frequent disassembly, making bolted connections unsuitable.

[0048] Screws: A type of fastener consisting of a head and a shank. They can be divided into three categories based on their use: machine screws, set screws, and special-purpose screws. They can be used with or without a nut. For example, when fastening a part with a set threaded hole to a part with a through hole, a nut is not required; when fastening two parts with through holes, a nut is required. This type of connection is called a screw connection and is also considered a detachable connection.

[0049] Self-tapping screws, also known as quick-thread screws, are quick-install fasteners made of steel with a galvanized, passivated surface. They are primarily used to connect thin metal sheets (such as steel and sawn metal). To connect, a threaded hole must be created in the connected parts, and the self-tapping screw is then screwed into the threaded hole.

[0050] Wood screws: Similar to machine screws, but with a special thread on the screw shaft, they can be screwed directly into wooden components (or parts). They are used to fasten a metal (or non-metal) part with a through hole to a wooden component. This connection is detachable.

[0051] Rivets: A type of fastener consisting of a head and a shank, used to securely connect two parts (or components) with holes, forming a single, integral unit. This type of connection is called a rivet joint, or simply a riveted joint, and is considered a non-detachable connection. To separate two parts connected by rivets, you must break the rivets.

[0052] 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 that it can be connected to other parts.

[0053] Pin: Mainly used for positioning parts. Some pins can also be used to connect parts, fix parts, transmit power or lock fasteners, etc.

[0054] In addition, in actual application scenarios, the above-mentioned bolts, studs or screws can be used in conjunction with nuts, washers, retaining rings, etc., and the embodiments of the present application do not impose any limitations on this.

[0055] Nut: A nut with an internal threaded hole, with shapes including but not limited to flat hexagonal, flat square or flat cylindrical. It is used with bolts, studs or screws to fasten two parts together to form a whole.

[0056] Washers: A type of fastener with a shape that includes, but is not limited to, an oblate ring. They can be placed between the support surface of a bolt, screw, or nut and the surface of the connected part, increasing the contact surface area between the connected parts, reducing the pressure per unit area, and protecting the surfaces from damage. Another type of washer is a spring washer, which can also prevent the nut from loosening.

[0057] 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.

[0058] With the increasing intelligence of vehicles, the number of on-board ECUs has increased dramatically, and the power consumption of ECUs has also increased significantly. For some ECUs with high power consumption that require active heat dissipation, currently known design solutions include the following two: First, the ECU can have a built-in liquid cooling structure (for the sake of ease of description, this ECU is referred to as an ECU with a built-in liquid cooling structure in this application), and the ECU with a built-in liquid cooling structure can be directly connected to the vehicle's thermal management device for cooling and heat dissipation; Second, an independent external liquid cooling plate is installed, and an ECU without a liquid cooling structure (for the sake of ease of description, this ECU is referred to as an ECU without a built-in liquid cooling structure in this application) is fixed to the liquid cooling plate. The liquid cooling plate is connected to the vehicle's thermal management device to cool and dissipate the heat of the ECU without a built-in liquid cooling structure fixed to the liquid cooling plate.

[0059] In other words, a vehicle may include both ECUs without built-in liquid cooling and ECUs with built-in liquid cooling. Some ECUs without built-in liquid cooling and with lower power consumption generate relatively low amounts of heat, and their own heat dissipation can ensure they operate in a suitable temperature environment. However, some ECUs without built-in liquid cooling and with higher power consumption generate relatively high amounts of heat, and their own heat dissipation alone cannot ensure they operate in a suitable temperature environment. Therefore, these ECUs without built-in liquid cooling and with higher power consumption also require thermal management devices to ensure they operate in a suitable temperature environment.

[0060] Figure 1 is a schematic diagram of a thermal management system. As shown in Figure 1, ECUs with built-in liquid cooling can be directly connected to the vehicle's thermal management system, becoming part of the vehicle's thermal management system. ECUs without built-in liquid cooling, on the other hand, need to be mounted on a separate liquid cooling plate, which is then connected to the vehicle's thermal management system, becoming part of the thermal management system. If there are a large number of ECUs without built-in liquid cooling and ECUs with built-in liquid cooling, the liquid cooling plate on which the ECUs are mounted needs to be connected to the thermal management system's water circuit, and the ECUs with built-in liquid cooling also need to be connected to the thermal management system's water circuit, resulting in complex water circuit connections within the thermal management system. Furthermore, both ECUs without built-in liquid cooling and ECUs with built-in liquid cooling need to communicate with the thermal management system's thermal management system, making communication within the thermal management system complex and system maintenance more difficult.

[0061] In response to the above problems, the embodiments of the present application provide an electronic control unit, a control system, and a terminal. By providing a fastening interface on an ECU without a self-liquid cooling structure and an ECU with a self-liquid cooling structure, and fastening the ECU without a self-liquid cooling structure and the ECU with a self-liquid cooling structure together based on the fastening interface, the liquid cooling structure of the ECU with a self-liquid cooling structure can be reused. There is no need to add an additional independent liquid cooling plate. It is only necessary to connect the ECU with a self-liquid cooling structure to the water path of the thermal management system. The connection of additional independent liquid cooling plates in the water path of the thermal management system is reduced, which can reduce the complexity of the thermal management system and thus reduce the difficulty of system maintenance. In addition, there is no need to purchase additional independent liquid cooling plates, which can reduce costs.

[0062] The first ECU and the second ECU provided in this application are described in detail below with reference to FIG. 2 to FIG. 4 .

[0063] FIG2 is a schematic diagram of a first ECU provided in an embodiment of the present application.

[0064] An embodiment of the present application provides a first ECU, which includes a liquid cooling structure and at least two fastening interfaces for installing fasteners, and the fasteners are used to fasten the first ECU to a second ECU that does not include a liquid cooling structure.

[0065] As mentioned above, fasteners are a general term for a class of mechanical parts used to fasten two or more parts (or components) together into a whole. Fasteners come in a wide variety of sizes and specifications, with varying performance and applications, and are highly standardized, serialized, and universal. In actual application scenarios, fastening interfaces can be configured based on different requirements. The specific form of the fastening interface corresponds to the fastener, and the fastening interface suitable for different types of fasteners can have different forms. This is not limited in the present application.

[0066] For example, as shown in Figure 2, Figure 2a) shows a three-dimensional stereoscopic image of a first ECU, and Figure 2b) shows a top view of the first ECU in Figure 2a), which includes a liquid cooling structure 210 and multiple fastening interfaces, such as fastening interface 221, fastening interface 222, fastening interface 223, fastening interface 224, fastening interface 225 and fastening interface 226.

[0067] At least two of the fastening interfaces included in the first ECU can be aligned with at least two of the fastening interfaces included in the second ECU, so as to facilitate fastening the second ECU to the first ECU.

[0068] As an example and not a limitation, as shown in FIG2 b), the positions of the fastening interfaces 221, 224, and 225 can be connected in a straight line, that is, the positions of the fastening interfaces 221, 224, and 225 are on the same straight line, while the positions of the fastening interfaces 222, 223, and 226 cannot be connected in a straight line, that is, the positions of the fastening interfaces 222, 223, and 226 are not on the same straight line. In this way, a second ECU of different sizes can be fastened to the first ECU through the fastening interfaces 221, 222, 223, 224, 225, and 226, which has good universality.

[0069] The following describes different sizes of the second ECU that can be adapted to the first ECU provided in the embodiment of the present application in conjunction with Figure 3.

[0070] FIG3 is a comparison diagram of different sizes of a second ECU adapted to a first ECU provided in an embodiment of the present application.

[0071] Example 1, as shown in a) of Figure 3, the second ECU of size 1 can be fastened together with the first ECU through the fastening interface 221 and the fastening interface 223, or the fastening interface 222 and the fastening interface 224, or the fastening interface 221, the fastening interface 222 and the fastening interface 223, or the fastening interface 221, the fastening interface 222 and the fastening interface 224, or the fastening interface 222, the fastening interface 223 and the fastening interface 224, or the fastening interface 221, the fastening interface 224 and the fastening interface 223, or the fastening interface 221, the fastening interface 222, the fastening interface 223 and the fastening interface 224.

[0072] Example 2, as shown in b) of Figure 3, the second ECU of size 2 can be fastened together with the first ECU through the fastening interface 223 and the fastening interface 225, or the fastening interface 221 and the fastening interface 226, or the fastening interface 221, the fastening interface 222 and the fastening interface 226, or the fastening interface 223, the fastening interface 224 and the fastening interface 225.

[0073] It is understandable that a second ECU of size 1 can be fastened to a first ECU, or one or two second ECUs of size 2 can be fastened to a first ECU; this embodiment of the present application does not impose any limitation on this.

[0074] It should be understood that the above-mentioned size 1 and size 2 are not strictly speaking sizes, but are only used to distinguish second ECUs of different sizes (or specifications) and should not impose any limitations on this application.

[0075] Figures 2 and 3 are only examples. In actual application scenarios, the first ECU may include more or fewer fastening interfaces, as long as the second ECU can be fastened to the first ECU. The embodiment of the present application does not limit the specific number of fastening interfaces included in the first ECU.

[0076] Optionally, the liquid cooling structure of the first ECU includes: a cavity for containing coolant, and a liquid inlet and a liquid outlet connected to the cavity, and the liquid cooling structure is integrally formed with the first electronic control unit.

[0077] As an example and not a limitation, as shown in FIG2 , the liquid cooling structure 210 of the first ECU may include a cavity 211, a liquid inlet 212, and a liquid outlet 213. Liquid cooling liquid may enter the cavity 211 through the liquid inlet 212 and then flow out of the cavity 211 through the liquid outlet 213. The liquid cooling structure 210 is integrally formed with the first ECU, that is, the liquid cooling structure 210 is a non-detachable part of the first ECU.

[0078] In a possible design, the first ECU further includes at least one heat-conducting groove, which is located on the outer surface of the cavity. The heat-conducting groove is used to hold a heat-conducting material, and the heat-conducting material is used to conduct heat.

[0079] As an example and not a limitation, as shown in FIG2 , the first ECU may further include heat conducting grooves 231 and 232. Before fastening the first and second ECUs together using fasteners, thermally conductive material may be placed in the heat conducting grooves to facilitate better heat conduction between the first and second ECUs. Thermally conductive materials include, but are not limited to, thermal pads, thermally conductive gels, and the like, and are not limited in this embodiment of the present application.

[0080] In a possible design, the first ECU is used to obtain the temperature of the second ECU.

[0081] The first ECU can obtain its own temperature, the second ECU can also obtain its own temperature. The first ECU and the second ECU can communicate, and the first ECU can obtain the temperature of the second ECU from the second ECU to facilitate subsequent processing based on the temperature of the first ECU and the temperature of the second ECU.

[0082] The ECU without self-liquid cooling structure and the ECU with self-liquid cooling structure that are fastened together can be regarded as a whole, and the first ECU and the second ECU can communicate internally based on the communication channel (for example, the first ECU obtains the temperature of the second ECU). Based on this, the first ECU only needs to communicate with the thermal management device, and the second ECU does not need to communicate with the thermal management device. This can reduce the complexity of the communication connection of the thermal management system to a certain extent, and further reduce the difficulty of system maintenance.

[0083] Based on the above scheme, by setting a fastening interface on the ECU with its own liquid cooling structure, and fastening the ECU without a self-cooling structure and the ECU with a self-cooling structure together based on the fastening interface, that is, the ECU without a self-cooling structure and the ECU with a self-cooling structure that are fastened together can be regarded as a whole, thereby reusing the liquid cooling structure of the ECU with a self-cooling structure, without adding an additional independent liquid cooling plate, and only needing to connect the ECU with a self-cooling structure to the water path of the thermal management system. This reduces the access of additional independent liquid cooling plates in the water path of the thermal management system, which can reduce the complexity of the thermal management system. Furthermore, the ECU without a self-cooling structure and the ECU with a self-cooling structure that are fastened together can be regarded as a whole, and the first ECU and the second ECU can communicate internally based on the communication channel. Based on this, the first ECU only needs to communicate with the thermal management device, and the second ECU does not need to communicate with the thermal management device. This can reduce the complexity of the communication connection of the thermal management system to a certain extent, and further reduce the difficulty of system maintenance. Furthermore, by reducing the complexity of the thermal management system's water and communication connections, the thermal management system can save a certain amount of space in the vehicle. Furthermore, there is no need to purchase a separate liquid cooling plate, which can reduce costs.

[0084] FIG4 is a schematic diagram of a second ECU provided in an embodiment of the present application.

[0085] An embodiment of the present application provides a second ECU, which does not include a liquid cooling structure. The second ECU includes at least two fastening interfaces for installing fasteners, and the fasteners are used to fasten the second ECU to the first ECU including the liquid cooling structure.

[0086] A detailed description of the fastening interface and fasteners can be found above, and for the sake of brevity, they will not be repeated here.

[0087] For example, as shown in Figure 4, Figure 4a) shows a three-dimensional stereoscopic image of a second ECU, and Figure 4b) shows an overhead view of the second ECU in Figure 4a), which includes multiple fastening interfaces, such as fastening interface 401, fastening interface 402, fastening interface 403 and fastening interface 404.

[0088] At least two of the fastening interfaces included in the second ECU can be aligned with at least two of the fastening interfaces included in the first ECU, so that the second ECU can be fastened to the first ECU.

[0089] As mentioned above, second ECUs of different sizes can be fastened together with the first ECU provided in the embodiment of the present application, that is, in actual application scenarios, second ECUs of different sizes can be included.

[0090] Example 1: For example, the size of the second ECU is size 1 as shown in FIG3 a). The following are several possible design methods for the second ECU of size 1:

[0091] Design method 1, the second ECU may include a fastening interface 401 and a fastening interface 403 as shown in b) of Figure 4, so that the fastening interface 401 and the fastening interface 403 of the second ECU can be aligned with the fastening interface 221 and the fastening interface 223 of the first ECU, so that the second ECU of size 1 can be fastened together with the above-mentioned first ECU.

[0092] Design method 2, the second ECU may include a fastening interface 402 and a fastening interface 404 as shown in b) of Figure 4, so that the fastening interface 402 and the fastening interface 404 of the second ECU can be aligned with the fastening interface 222 and the fastening interface 224 of the first ECU, so that the second ECU of size 1 can be fastened together with the above-mentioned first ECU.

[0093] Design method 3, the second ECU may include a fastening interface 401, a fastening interface 402 and a fastening interface 403 as shown in b) of Figure 4.

[0105] It can be understood that Figure 4 is only an example. In actual application scenarios, the second ECU may include more or fewer fastening interfaces, as long as the second ECU can be fastened to the first ECU. The embodiment of the present application does not limit the specific number of fastening interfaces included in the second ECU.

[0106] Based on the above solution, by setting a fastening interface on the ECU without a self-contained liquid cooling structure, and fastening the ECU without a self-contained liquid cooling structure and the ECU with a self-contained liquid cooling structure together based on the fastening interface, that is, the ECU without a self-contained liquid cooling structure and the ECU with a self-contained liquid cooling structure that are fastened together can be regarded as a whole, thereby reusing the liquid cooling structure of the ECU with a self-contained liquid cooling structure. There is no need to add an additional independent liquid cooling plate. It is only necessary to connect the ECU with a self-contained liquid cooling structure to the water path of the thermal management system. The connection of additional independent liquid cooling plates in the water path of the thermal management system is reduced, which can reduce the complexity of the thermal management system. In addition, there is no need to purchase additional independent liquid cooling plates, which can reduce costs.

[0107] The control system provided by this application is described in detail below with reference to FIG5 .

[0108] The present application also provides a control system, which includes a first ECU and a second ECU, the first ECU includes a liquid cooling structure, and the second ECU does not include a liquid cooling structure; wherein, the first ECU and the second ECU each include at least two fastening interfaces, and the at least two fastening interfaces are used to install fasteners, and the fasteners are used to fasten the first ECU and the second ECU.

[0109] It is understandable that one or more second ECUs can be fastened to the surface where the liquid cooling structure of a first ECU is located, and this embodiment of the present application does not impose any limitation on this.

[0110] FIG5 is a schematic diagram of a control system provided in an embodiment of the present application. As shown in FIG5 , the system includes a first ECU 501, a second ECU 502, a first ECU 503, a second ECU 504, and a second ECU 505. The first ECU 501 and the second ECU 502 can be fastened together via a fastening interface, and the first ECU 503 and the second ECU 504 and the second ECU 505 can be fastened together via a fastening interface.

[0111] As an example and not a limitation, the size of the second ECU 502 may be the size 1 described above, and the sizes of the second ECU 504 and the second ECU 505 may be the size 2 described above. This embodiment of the present application does not impose any limitation on this.

[0112] For example, the first ECU 501 and the first ECU 503 may include the fastening interface 221 , the fastening interface 222 , the fastening interface 223 , the fastening interface 224 , the fastening interface 225 , and the fastening interface 226 as shown in FIG. 2 .

[0113] Regarding how to fasten the second ECU 502 to the first ECU 501, and how to fasten the second ECU 504 and the second ECU 505 to the first ECU 503, please refer to Figure 3 and the description related to Figure 3 mentioned above. For the sake of brevity, they are not repeated here.

[0114] Optionally, the liquid cooling structure of the first ECU includes: a cavity for containing coolant, and a liquid inlet and a liquid outlet connected to the cavity, and the liquid cooling structure is integrally formed with the first electronic control unit.

[0115] For the relevant description of the liquid cooling structure, please refer to the relevant description above. For the sake of brevity, it will not be repeated here.

[0116] In one possible design, the first ECU further includes at least one heat-conducting groove, which is located on the outer surface of the cavity and has an opening facing the second ECU. The heat-conducting groove is used to hold heat-conducting material, and the heat-conducting material is used to conduct heat.

[0117] For the relevant description of the heat conduction groove, please refer to the relevant description above. For the sake of brevity, it will not be repeated here.

[0118] In a possible implementation, the first ECU and the second ECU communicate with each other based on a communication channel, and the communication channel includes a CAN bus, a CAN-FD bus, an Ethernet, or a wireless network.

[0119] Exemplarily, as shown in Figure 5, the second ECU 502 is fastened to the first ECU 501, and the second ECU 504 and the second ECU 505 are fastened to the first ECU 503. The second ECU 502 and the first ECU 501, as well as the second ECU 504 and the first ECU 503, and the second ECU 505 and the first ECU 503 can communicate through a CAN bus, a CAN-FD bus, an Ethernet or a wireless network. That is, the second ECU 502 and the first ECU 501, as well as the second ECU 504 and the first ECU 503, and the second ECU 505 and the first ECU 503 can be physically connected through a CAN bus or a CAN-FD bus, or can be physically connected through an Ethernet cable, or can be wirelessly connected through a wireless network. The embodiments of the present application do not impose any limitations on this.

[0120] In a possible implementation manner, the first ECU is configured to obtain the temperature of the second ECU from the second ECU based on a communication channel.

[0121] As mentioned above, the first ECU can obtain its own temperature, and the second ECU can also obtain its own temperature. The first and second ECUs can communicate via the aforementioned communication channel, thereby enabling the first ECU to obtain the second ECU's temperature from the second ECU, thereby facilitating subsequent processing based on the temperatures of the first and second ECUs.

[0122] ECUs without self-contained liquid cooling and ECUs with self-contained liquid cooling that are fastened together can be considered a single entity, and the first and second ECUs can communicate internally via a communication channel (for example, the first ECU obtains the temperature of the second ECU). Therefore, the first ECU only needs to communicate with the thermal management device, and the second ECU does not need to communicate internally with the thermal management device. As shown in Figure 5, first ECU 501 can obtain its own temperature and obtain the temperature of second ECU 502 from second ECU 502 via a communication channel with it. First ECU 503 can obtain its own temperature and obtain the temperature of second ECU 504 from second ECU 504 via a communication channel with it, and can also obtain the temperature of second ECU 505 from second ECU 505 via a communication channel with it. Then, the first ECU 501 and the first ECU 503 communicate with the thermal management device, and there is no need for the second ECU 502, the second ECU 504 and the second ECU 505 to communicate with the thermal management device, thereby reducing the complexity of the communication connection of the thermal management system to a certain extent and further reducing the difficulty of system maintenance.

[0123] Optionally, the control system further includes a thermal management device, to which the liquid cooling structure of the first ECU is connected, and the thermal management device is used to control a target temperature and / or a target flow rate of the coolant flowing out of the thermal management device.

[0124] Exemplarily, as shown in FIG5 , the control system includes a thermal management device 510 , to which the liquid cooling structures of the first ECU 501 and the first ECU 503 can be connected, and the thermal management device can be used to control the target temperature and / or target flow rate of the coolant flowing out of the thermal management device.

[0125] It should be understood that FIG5 is only an example. In actual application scenarios, the control system may include more or fewer first ECUs, and may also include more or fewer second ECUs. The embodiments of the present application do not impose any limitations on this.

[0126] Although not shown in FIG5 , the thermal management device may also include a liquid inlet and a liquid outlet. For example, the liquid inlet of the liquid cooling structure of the first ECU 501 and the first ECU 503 may be connected to the liquid outlet of the thermal management device 510, and the liquid outlet of the liquid cooling structure of the first ECU 501 and the first ECU 503 may be connected to the liquid inlet of the thermal management device 510, thereby enabling the circulation of coolant between the thermal management device and the liquid cooling structure of the first ECU, thereby ensuring that the first ECU and the second ECU in the control system operate in an appropriate temperature environment.

[0127] It can be understood that the control system including the thermal management device is the thermal management system (TMS) mentioned above.

[0128] In one possible implementation, the first ECU is also used to report indication information of the required coolant temperature and / or required flow rate to the thermal management device based on the temperature of the first ECU and the temperature of the second ECU; the thermal management device is specifically used to: receive indication information reported by multiple first ECUs; and control the target temperature and / or target flow rate based on the multiple indication information received.

[0129] Among them, the indication information may include the required temperature and / or required flow rate, or may not include the required temperature and / or required flow rate. The embodiment of the present application does not limit the specific content included in the indication information, as long as the required temperature and / or required flow rate can be obtained based on the indication information.

[0130] For example, after the first ECU obtains its own temperature and the temperature of the second ECU, the first ECU can determine the required temperature and / or required flow rate of the liquid coolant based on its own temperature and the temperature of the second ECU, and can generate indication information of the required temperature and / or required flow rate of the coolant, and can report the indication information to the thermal management device.

[0131] For example, after obtaining its own temperature and the temperature of the second ECU 502, the first ECU 501 can determine the required temperature and / or required flow rate of the liquid coolant of the first ECU 501 and the second ECU 502 based on its own temperature and the temperature of the second ECU 502, and can generate indication information of the required temperature and / or required flow rate of the coolant, and can report the indication information to the thermal management device.

[0132] For another example, after obtaining its own temperature and the temperatures of the second ECU 504 and the second ECU 505, the first ECU 503 can determine the required temperature and / or required flow rate of the liquid coolant of the first ECU 501, the second ECU 504 and the second ECU 505 based on its own temperature and the temperatures of the second ECU 504 and the second ECU 505, and can generate indication information of the required temperature and / or required flow rate of the coolant, and can report the indication information to the thermal management device.

[0133] Accordingly, the thermal management device can receive indication information reported by multiple first ECUs and control the target temperature and / or target flow rate of the coolant flowing out of the thermal management device based on the multiple indication information received. For example, the thermal management device 510 can receive indication information reported by the first ECU 501 and the first ECU 503, and determine the target temperature and / or target flow rate based on the indication information reported by the first ECU 501 and the first ECU 503, and control the temperature and / or flow rate of the coolant flowing out of the thermal management device based on the target temperature and / or target flow rate.

[0134] By way of example and not limitation, the thermal management device may determine multiple required temperatures and / or required flow rates based on the multiple received indication information, and then determine the temperature with the smallest value among the multiple required temperatures as the target temperature of the coolant flowing out of the thermal management device, and / or determine the flow rate with the largest value among the multiple required flow rates as the target flow rate of the coolant flowing out of the thermal management device. This embodiment of the present application is not limited in any way.

[0135] It is understood that when the second ECU is securely connected to the first ECU, the first ECU can determine the required temperature and / or required flow rate of the liquid coolant based on the temperature of the first ECU and the temperature of the second ECU, and thereby generate information indicating the required temperature and / or required flow rate of the coolant; when the first ECU is not securely connected to the second ECU, the first ECU can determine the required temperature and / or required flow rate of the liquid coolant based on its own temperature, and thereby generate information indicating the required temperature and / or required flow rate of the coolant. This embodiment of the present application is not limited to this.

[0136] In another possible implementation, the first ECU is also used to report the temperature of the first ECU and the temperature of the second ECU to the thermal management device; the thermal management device is specifically used to: receive temperatures reported by multiple first ECUs; and control the target temperature and / or target flow rate based on the multiple temperatures received.

[0137] For example, after obtaining its own temperature and the temperature of the second ECU, the first ECU may report its own temperature and the temperature of the second ECU to the thermal management device.

[0138] For example, after obtaining its own temperature and the temperature of the second ECU 502 , the first ECU 501 may report its own temperature and the temperature of the second ECU 502 to the thermal management device.

[0139] For another example, after obtaining its own temperature and the temperatures of the second ECU 504 and the second ECU 505 , the first ECU 503 may report its own temperature and the temperatures of the second ECU 504 and the second ECU 505 to the thermal management device.

[0140] Accordingly, the thermal management device can receive temperatures reported by multiple first ECUs and control the target temperature and / or target flow rate of the coolant flowing out of the thermal management device based on the received temperatures. For example, the thermal management device 510 can receive the temperatures of the first ECU 501 and the first ECU 503 reported by the first ECU 501, as well as the temperatures of the first ECU 503, the second ECU 504, and the second ECU 505 reported by the first ECU 503, and determine a target temperature and / or target flow rate based on these temperatures, and control the temperature and / or flow rate of the coolant flowing out of the thermal management device based on the target temperature and / or target flow rate.

[0141] As an example and not a limitation, the thermal management device may control the target temperature and / or target flow rate of the coolant flowing out of the thermal management device based on the temperature with the largest value among the multiple temperatures received. This embodiment of the present application does not impose any limitation on this.

[0142] It should be understood that the thermal management device may include a processor and a receiving unit. The receiving unit may be configured to receive indication information or temperatures reported by the plurality of first ECUs. The processor may be configured to control a target temperature and / or target flow rate of the coolant flowing out of the thermal management device based on the indication information or temperatures received by the receiving unit. Furthermore, the thermal management device may further include a memory, which may be configured to store program instructions and / or data. The memory may be located within or outside the processor, and this is not limited in any way in the present embodiment.

[0143] It is understood that when the second ECU is securely connected to the first ECU, the first ECU can report its own temperature and the temperature of the second ECU to the thermal management device; and when the first ECU is not securely connected to the second ECU, the first ECU can report its own temperature to the thermal management device. This embodiment of the present application is not limited to this.

[0144] Based on the above solution, by providing a fastening interface on the ECU without a self-contained liquid cooling structure and the ECU with a self-contained liquid cooling structure, and fastening the non-liquid cooling structure ECU and the self-contained liquid cooling structure ECU together based on the fastening interface, that is, the fastened ECU without a self-contained liquid cooling structure and the ECU with a self-contained liquid cooling structure can be regarded as a whole, thereby reusing the liquid cooling structure of the ECU with a self-contained liquid cooling structure, without the need to add an additional independent liquid cooling plate. It is only necessary to connect the ECU with the self-contained liquid cooling structure to the water path of the thermal management system. This reduces the connection of additional independent liquid cooling plates in the water path of the thermal management system, which can reduce the complexity of the thermal management system. Furthermore, the fastened ECU without a self-contained liquid cooling structure and the ECU with a self-contained liquid cooling structure can be regarded as a whole, and the first ECU and the second ECU can communicate internally based on the communication channel. Based on this, the first ECU only needs to communicate with the thermal management device, and the second ECU does not need to communicate with the thermal management device. This can reduce the complexity of the communication connection of the thermal management system to a certain extent and further reduce the difficulty of system maintenance. Furthermore, by reducing the complexity of the thermal management system's water and communication connections, the thermal management system can save a certain amount of space in the vehicle. Furthermore, there is no need to purchase a separate liquid cooling plate, which can reduce costs.
