These aspects all comply with corresponding laws and regulations and relevant provisions. In embodiments of the present disclosure, all data collection, acquisition, processing, processing, forwarding, use, etc. are carried out on the premise that the user is aware of and confirms. Accordingly, when implementing each embodiment of the present disclosure, the type of data or information that can be involved, the scope of use, the scenario of use, etc. should be informed to the user and the authorization of the user should be obtained through appropriate means according to relevant laws and regulations. The specific way of informing and / or authorization can vary according to the actual situation and application scenario, and the scope of the present disclosure is not limited in this respect.

[0032] The principles of the present disclosure will be described below with reference to several example embodiments shown in the accompanying drawings. Although the preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the description of these embodiments is only to enable those skilled in the art to better understand and implement the present disclosure, and is not intended to limit the scope of the present disclosure in any way.

[0033] As mentioned earlier, today's cars are equipped with numerous sensors, electronic control units (ECUs), and complex software systems to support a wide range of functions from navigation, entertainment, to safety features. These advanced systems greatly enhance the performance and driving convenience of vehicles, but at the same time, they make the overall structure of the vehicle more complex, significantly increasing the number of required components and modules.

[0034] This complexity not only presents higher requirements in the manufacturing and design process, but also makes the maintenance and repair of vehicles more difficult. A large number of connections and communications are required between sensors and electronic systems inside modern vehicles, which complicates the diagnosis and handling of problems. When a vehicle is repaired, it is not just a simple replacement of parts, but also a detailed detection of the system, and may involve software updates or reprogramming. Such operations often require the intervention of professional technicians and may also require the use of expensive diagnostic equipment and specific software authorization.

[0035] With the increase in vehicle functions and system complexity, the maintenance cost of vehicles is also rising. In addition to traditional mechanical maintenance, modern vehicles also need to face the upgrading of software systems, which makes the maintenance work more complex and time-consuming. At the same time, as vehicles become more dependent on software control, network security issues have become an important consideration, further increasing the cost of maintenance. Therefore, although modern vehicles bring unprecedented convenience and excellent performance to drivers, the high maintenance cost has become a realistic challenge for both car owners and manufacturers.

[0036] Embodiments of the present disclosure provide a domain controller to solve or at least partially solve the above-mentioned problems or other potential problems existing in traditional domain controllers. The domain controller according to the embodiments of the present disclosure integrates at least two domain function modules and uses a water-cooled assembly for heat dissipation, thereby improving the system integration while ensuring the stability and reliability of the domain controller.

[0037] As will be mentioned below, the domain referred to herein, i.e., the "domain" of the vehicle, refers to the division of the vehicle's electronic systems into different control areas according to function, with each domain responsible for managing a group of related subsystems and components. This division helps to simplify the complexity of the vehicle's electronic and electrical architecture (EEA) and improve the overall efficiency and maintainability of the system.

[0038] In vehicle architecture, each electronic control unit (ECU) is usually responsible for a specific function, such as engine management, brake system, or infotainment system. As the number of vehicle functions increases, this distributed ECU approach can result in a large number of individual control units in the system, which require complex communication and connections between them. To facilitate management and maintenance, automobile manufacturers have begun to adopt the concept of domain function modules, referred to as domain function modules hereinafter. A domain function module is a more centralized control unit that integrates multiple related ECUs into a more powerful computing platform. For example, domain function module 102 can include a power domain function module, a chassis domain function module, a safety domain function module, a cabin domain function module, an intelligent driving domain function module, a networking domain function module, and a multi-domain auxiliary function module, etc.

[0039] The power domain function module is used to manage systems related to the vehicle powertrain, such as engine control, transmission control, battery management, and hybrid power systems. The chassis domain function module is responsible for the vehicle's driving dynamics, including suspension control, brake system, steering system, and tire pressure monitoring. The safety domain function module is responsible for the vehicle's safety systems, such as airbag control, vehicle anti-theft system, etc., to ensure the safety of the vehicle and passengers.

[0040] The cabin domain function module manages the driver and passenger's cabin experience, including infotainment systems, instrument panels, driver assistance systems, and human-machine interfaces. The intelligent driving domain function module is responsible for advanced driver assistance systems (ADAS) and autonomous driving functions, such as cameras, radars, LiDARs, and sensor fusion. The networking domain function module handles vehicle communication with the outside world, including vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), and vehicle-to-cloud (V2C) connections.

[0041] The multi-domain auxiliary function module includes high-performance processors such as X86 architecture CPUs and GPUs. These processors are used to assist in processing complex calculations involved in other domains, such as real-time image processing, sensor data analysis, decision-making for advanced driver assistance systems (ADAS), etc. The introduction of the multi-domain auxiliary function module can improve the computing power of the vehicle, meeting the needs of higher levels of autonomous driving and intelligent cabin.

[0042] According to the domain controller of the embodiment of the present disclosure, at least two of the above-mentioned domain function modules are fused, thereby further simplifying the complexity of the vehicle electronic and electrical architecture and improving the overall efficiency and maintainability of the system.

[0043] The concept according to the embodiments of the present disclosure will be described below in conjunction with FIGS. 1-4. FIG. 1 shows a perspective view of a domain controller according to an embodiment of the present disclosure, and FIG. 2 shows an exploded view of the domain controller. As shown in FIGS. 1 and 2, generally, the domain controller according to an embodiment of the present disclosure includes a housing 101, at least two domain function modules 102, and a water-cooling assembly 103.

[0044] The housing 101 includes at least one layer of accommodation space. For example, as shown in FIG. 2, the housing 101 of the domain controller includes two layers of accommodation space for accommodating the domain function modules 102 and the water-cooling assembly 103, respectively. Hereinafter, the concept of the present disclosure will be mainly described by way of example with the housing 101 having two layers of accommodation space. It should be understood that the concept of the present disclosure is also similar for the case of having other numbers of layers of accommodation space, which will not be described again in detail hereinafter.

[0045] The at least two domain function modules 102 are arranged in the at least one layer of accommodation space, and are used to respectively implement the domain functions of at least two domains of a vehicle. For example, in some embodiments, the at least two domain function modules 102 can be at least two of the domain function modules mentioned above, i.e., the at least two domain function modules 102 include at least two of the following: a power domain function module, a chassis domain function module, a safety domain function module, a cabin domain function module, an intelligent driving domain function module, a networking domain function module, and a multi-domain auxiliary function module.

[0046] In order to cope with the high heat brought by the fusion of multi-domain function modules, the water-cooling assembly 103 according to an embodiment of the present disclosure is arranged in the at least one layer of accommodation space. The water-cooling assembly 103 includes a pair of water-cooling plates 1031 and a heat-conducting component 1033. Each water-cooling plate 1031 of the pair of water-cooling plates 1031 includes a meandering flow channel 1032, and the meandering flow channels 1032 of the pair of water-cooling plates 1031 are in series communication, as shown in FIG. 2. In some embodiments, the cooling liquid in the meandering flow channels 1032 can be circulated within the meandering flow channels 1032 by a pumping element. The meandering flow channels 1032 between the pair of water-cooling plates 1031 can be in series communication by a pipe, so that the cooling liquid can be circulated in the meandering flow channels 1032 of the two water-cooling plates by a set of pumping elements.

[0047] The heat-generating components 1021 of the at least two domain function modules 102 according to an embodiment of the present disclosure are arranged on at least one side of the pair of water-cooling plates 1031, and the heat-conducting component 1033 is located between the water-cooling plates 1031 and the heat-generating components 1021 (e.g., processors). In this way, the water-cooling plates 1031 can effectively dissipate heat for the plurality of domain control modules, thereby improving the stability and reliability of the domain controller 100.

[0048] The specific structure of the housing 101 will be described below in conjunction with FIG. 1 and FIG. 2. In some embodiments, the housing 101 can include a first housing assembly 1011 and a first cover 1012. The first housing assembly 1011 includes a first bottom shell and a pair of first side walls extending from the first bottom shell toward a first side. The first cover 1012 is arranged to be coupled to the pair of first side walls of the first housing assembly 1011 from the first side to form a first accommodation space in the at least one accommodation space. The first accommodation space is used to accommodate a first water-cooling plate in the pair of water-cooling plates 1031. Meanwhile, the first accommodation space also accommodates part of the domain function modules in the at least two domain control modules 102.

[0049] For example, in some embodiments, a plurality of domain function modules can be arranged on both sides of the first water-cooling plate 1031, and the corresponding heat-generating components 1021 are coupled to the water-cooling plate 1031 through the heat-conducting components 1033 for effective heat dissipation and cooling.

[0050] In some embodiments, the housing 101 further includes a second housing assembly 1013 and a second cover 1014. The second housing assembly 1013 includes a second bottom shell 1019 and a pair of second side walls 1010 extending from the second bottom shell 1019 toward a second side. The second bottom shell 1019 is coupled to the second side of the first bottom shell.

[0051] As shown in FIG. 3, the second housing assembly 1013 can be formed with a support portion 1020. The support portion 1020 can be supported at a predetermined position when the domain controller 100 is placed horizontally to facilitate the installation and fixation of the domain controller. In this context, when the domain controller 100 is placed horizontally, the first side can represent the upper side and the second side can represent the lower side. Of course, it should be understood that when the domain controller adopts other installation or fixation orientations, the first side and the second side respectively represent the corresponding orientations corresponding to the respective orientations, which will not be described again in the following.

[0052] The second cover 1014 is arranged to be coupled to the pair of second side walls 1010 of the second housing assembly 1013 from the second side to form a second accommodation space, which is used to accommodate a second water-cooling plate 1031 in the pair of water-cooling plates 1031. Meanwhile, similar to the first accommodation space, the second accommodation space can also accommodate part of the domain function modules in the at least two domain control modules 102. For example, in some embodiments, a plurality of domain function modules 102 can be arranged on both sides of the second water-cooling plate 1031, and the corresponding heat-generating components 1021 are coupled to the water-cooling plate 1031 through the heat-conducting components 1033 for effective heat dissipation and cooling.

[0053] As can be seen from the above description, the at least two domain function modules 102 can include a plurality of domain function modules arranged in the first accommodation space and located at the first side and the second side of the first water-cooled plate 1031 respectively; and another plurality of domain function modules arranged in the second accommodation space and located at the first side and the second side of the second water-cooled plate 1031 respectively.

[0054] In some embodiments, the housing 101 further includes a pair of first auxiliary cover plates 1015. The pair of first auxiliary cover plates 1015 are arranged between the first cover body 1012 and the first bottom shell and located between the ends of the pair of first side walls respectively. The pair of first auxiliary cover plates 1015 include a plurality of first accommodation holes 1017 through which part of the connection ports in the at least two domain function modules 102 pass. These connection ports can include, but are not limited to, peripheral component interconnect express (PCIe) bus ports, Ethernet ports, diagnostic ports (such as OBD-II), power supply ports, controller area network bus (CAN) ports, etc. These ports can be connected with corresponding data lines or power supply lines, so as to be connected with external devices or other domain function modules in the domain controller.

[0055] In some embodiments, the housing 101 further includes a second auxiliary cover plate 1016. The second auxiliary cover plate 1016 is arranged between the second cover body 1014 and the second bottom shell 1019 and located between the ends of the pair of second side walls 1010, so as to seal the opening between the ends of the pair of second side walls 1010. The second auxiliary cover plate 1016 includes a plurality of second accommodation holes 1018 through which part of the connection ports in the at least two domain function modules pass. Similar to the first accommodation holes 1017, these ports can include, but are not limited to, peripheral component interconnect express (PCIe) bus ports, Ethernet ports, diagnostic ports (such as OBD-II), power supply ports, controller area network bus (CAN) ports, etc.

[0056] In addition, in some embodiments, at least one of the pair of first side plates, at least one of the pair of second side plates, and the part of the first cover body 1012 coupled with the pair of first side plates can include a plurality of third accommodation holes through which part of the connection ports in the at least two domain function modules 102 pass. In addition to providing accommodation for the above-mentioned plurality of ports, the third accommodation holes can also provide accommodation for the liquid inlet and outlet.

[0057] In some embodiments, in order to improve the sealing performance, at least one of the light-cured sealant, the naturally-cured sealant, the sealing partition and the sealing ring is used to seal between the first housing assembly 1011, the first cover 1012 and the pair of first auxiliary cover plates 1015, and between the second housing assembly 1013, the second cover 1014 and the second auxiliary cover plate 1016. Different sealing methods can be applied to the corresponding appropriate positions, so as to improve the sealing performance of the entire domain controller, and improve the anti-condensation performance.

[0058] For example, in some embodiments, the domain controller can include a pair of first sealing partitions and a second sealing partition. The pair of sealing partitions are respectively arranged on the inner side of the pair of first auxiliary cover plates 1015, and the second sealing partition is arranged on the inner side of the second auxiliary cover plate 1016. In other appropriate positions between the first housing assembly 1011 and the first cover 1012, and between the second housing assembly 1013 and the second cover 1014, the light-cured sealant, the naturally-cured sealant and / or the sealing ring can be provided to further improve the sealing performance.

[0059] For at least part of the plurality of domain function modules 102, in order to improve the shock absorption performance, the domain controller can further include a shock absorption component. The shock absorption component is arranged between at least one of the first housing assembly 1011 and the second housing assembly 1013 and at least two domain function modules. The shock absorption component can include an elastic component, which can effectively reduce the risk of damage to part of the domain function modules caused by the domain controller during the jolt of the vehicle, and further improve the reliability of the domain controller.

[0060] In some embodiments, as shown in FIG. 4, the water cooling assembly 103 further includes a uniform temperature plate 1036. The uniform temperature plate 1036, also known as a VC uniform temperature plate (Vapor Chamber), is a kind of high-efficiency thermal management technology component, which can quickly transfer and dissipate heat through rapid phase change circulation, and can effectively reduce local overheating and maintain uniform temperature inside the device. The uniform temperature plate 1036 is arranged between the pair of water cooling plates 1031 and the heat generating component 1021. The uniform temperature plate 1036 includes support columns arranged inside to support the internal receiving cavity, and a capillary structure arranged in the internal receiving cavity to facilitate heat transfer from the heat generating component 1021 to the pair of water cooling plates 1031 through phase change of the fluid in the internal receiving cavity.

[0061] By using the uniform temperature plate 1036, the heat generating components 1021 such as computing units and storage units of each domain function module 102 in the domain controller can be effectively cooled, and the effectiveness of cooling is further improved, thereby improving the reliability of the domain controller.

[0062] In some embodiments, in order to further improve the cooling effect, the water-cooling plate 1031 can further include heat dissipation fins 1034 arranged in the meandering flow channel 1032, as shown in FIG. 5. The heat dissipation fins 1034 can be arranged at least at positions in the meandering flow channel 1032 corresponding to the thermal coupling portions, so as to allow the cooling liquid to flow therethrough, thereby increasing the heat dissipation area of the cooling liquid. The thermal coupling portion is the position at which the heat generating component 1021 is coupled to the meandering flow channel 1032 of the water-cooling plate 1031 via the heat conduction component 1033. It should be understood that the heat dissipation fins 1034 can be arranged at any other positions in the meandering flow channel 1032 in addition to the positions corresponding to the thermal coupling portions.

[0063] In some embodiments, for heat generating components 1021 that are more concentrated in heat, such as SOC chips of integrated packages, a thermoelectric cooler (TEC) can be arranged between the heat generating components 1021 and the thermal coupling portions of the meandering flow channel 1032. As shown in FIG. 6, for the SOC chip of the cabin domain function module, a TEC can be arranged between the chip and the thermal coupling portions. In this way, the chip surface temperature can be made much lower than the cooling liquid temperature (generally liquid cooling, the chip surface temperature is higher than the cooling liquid temperature), effectively reducing the chip temperature and improving the liquid cooling effect.

[0064] In addition, the scheme according to the embodiments of the present disclosure can also set the voltage applied to the thermoelectric cooler 1035 according to the temperature of the heat generating component 1021, thereby achieving adaptive adjustment of the temperature of the heat generating component 1021. Specifically, in some embodiments, the cooling device can also have a control component. The control component is coupled to the thermoelectric cooler 1035, and can adjust the voltage applied to the thermoelectric cooler 1035 according to the temperature of the heat generating component 1021 to which the thermoelectric cooler 1035 is coupled.

[0065] The embodiments of the present disclosure also provide a vehicle. The vehicle includes the domain controller mentioned above. By using the domain controller according to the embodiments of the present disclosure, the performance and reliability of the vehicle can be improved.

[0066] The above has described the embodiments of the present disclosure, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those skilled in the art without departing from the scope and spirit of the described embodiments. The selection of the terms used herein is intended to best explain the principles, practical application, or technical improvement of the technology in the market of the embodiments, or to enable other ordinary skilled persons in the art to understand the embodiments disclosed herein.
