Rather, these embodiments are provided to provide a more thorough and complete understanding of this disclosure. It should be understood that the accompanying drawings and embodiments of this disclosure are for illustrative purposes only and are not intended to limit the scope of protection of this disclosure.

The term "based on" should be understood as "at least partially based on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment".

In the embodiments of this disclosure, all data collection, acquisition, processing, manipulation, forwarding, and use are conducted with the user's knowledge and confirmation. Accordingly, in implementing the embodiments of this disclosure, the type, scope of use, and usage scenarios of any data or information that may be involved should be communicated to the user and their authorization obtained in accordance with relevant laws and regulations through appropriate means. The specific methods of notification and / or authorization may vary depending on the actual situation and application scenario, and the scope of this disclosure is not limited in this respect.

[0031] The principles of this disclosure will now be described with reference to several exemplary embodiments illustrated in the accompanying drawings. While preferred embodiments of this disclosure are shown in the drawings, it should be understood that these embodiments are described only to enable those skilled in the art to better understand and implement this disclosure, and are not intended to limit the scope of this disclosure in any way.

[0032] As mentioned earlier, modern cars are equipped with numerous sensors, electronic control units (ECUs), and complex software systems to support a wide range of uses, from navigation and entertainment to safety features. These advanced systems greatly enhance vehicle performance and driving convenience, but they also make the overall structure of the vehicle more complex, significantly increasing the number of components and modules required.

[0033] This complexity not only places higher demands on the manufacturing and design processes but also makes vehicle maintenance and repair more challenging. Modern vehicles require extensive connections and communication between sensors and electronic systems, which complicates problem diagnosis and resolution. Vehicle repair often involves more than simple parts replacement; it requires detailed system testing and may involve software updates or reprogramming. Such operations typically require the intervention of specialized technicians and may necessitate the use of expensive diagnostic equipment and specific software licenses.

[0034] As vehicle functionality increases and system complexity grows, vehicle maintenance costs are also rising. Beyond traditional mechanical repairs, modern vehicles face constantly evolving software systems, making maintenance more complex and time-consuming. Simultaneously, as vehicles rely more heavily on software control, cybersecurity has become a significant consideration, further increasing maintenance costs. Therefore, while modern vehicles offer unprecedented convenience and superior performance, high maintenance costs remain a real challenge for both owners and manufacturers.

[0035] Embodiments of this disclosure provide a domain controller to solve, or at least partially solve, the aforementioned problems or other potential problems existing in conventional domain controllers. The domain controller according to embodiments of this disclosure improves system integration while ensuring the stability and reliability of the domain controller by integrating at least two domain function modules and employing water-cooling components for heat dissipation.

[0036] As will be discussed below, the "domain" referred to in this article is the vehicle's "domain," which means dividing the vehicle's electronic system into different control areas according to function. Each domain is responsible for managing a set of related subsystems and components. This division helps to simplify the complexity of the vehicle's electrical and electronic architecture (EEA) and improve the overall efficiency and maintainability of the system.

[0037] In vehicle architecture, each Electronic Control Unit (ECU) typically handles a specific function, such as engine management, braking system, or infotainment system. As vehicle functions increase, this distributed ECU approach results in a large number of individual control units within the system, requiring complex communication and connectivity between them. To facilitate management and maintenance, automakers have begun adopting the concept referred to below as domain function modules. 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 may include powertrain domain function modules, chassis domain function modules, safety domain function modules, cockpit domain function modules, intelligent driving domain function modules, connectivity domain function modules, and multi-domain auxiliary function modules, etc.

[0038] The powertrain domain module manages systems related to the vehicle's powertrain, such as engine control, transmission control, battery management, and hybrid systems. The chassis domain module is responsible for vehicle dynamics, including suspension control, braking systems, steering systems, and tire pressure monitoring. The safety domain module is responsible for vehicle safety systems, such as airbag control and anti-theft systems, ensuring the safety of the vehicle and its passengers.

[0039] The cockpit domain functional module manages the cockpit experience for the driver and passengers, including the infotainment system, instrument panel, driver assistance systems, and human-machine interface. The intelligent driving domain functional module is responsible for advanced driver assistance systems (ADAS) and autonomous driving functions, such as cameras, radar, LiDAR, and sensor fusion. The connectivity domain functional module handles vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), and vehicle-to-cloud (V2C) connectivity.

[0040] The multi-domain assistance module includes high-performance processors such as x86 architecture CPUs and GPUs. These processors assist in handling complex calculations involved in other domains, such as real-time image processing, sensor data analysis, and decision-making for advanced driver assistance systems (ADAS). The introduction of the multi-domain assistance module can improve the vehicle's computing power and meet the needs of higher levels of autonomous driving and intelligent cockpits.

[0041] The domain controller according to the embodiments of this disclosure integrates at least two of the above-mentioned domain functional modules, thereby further simplifying the complexity of the vehicle's electronic and electrical architecture and improving the overall efficiency and maintainability of the system.

[0042] The following will combine Figures 1 to 4 To describe the concept according to embodiments of the present disclosure. Figure 1 A perspective view of a domain controller according to an embodiment of the present disclosure is shown, and Figure 2 This shows a breakdown view of the domain controller. (As shown...) Figure 1and Figure 2 As shown, the domain controller according to an embodiment of the present disclosure generally includes a housing 101, at least two domain function modules 102, and a water-cooling assembly 103.

[0043] The housing 101 includes at least one receiving space. For example, Figure 2 As shown, the domain controller housing 101 includes two layers of accommodating spaces, one for accommodating the domain function module 102 and the other for accommodating the water-cooling assembly 103. The following description will primarily focus on the two-layer accommodating space within the housing 101 as an example of the concept of this disclosure. It should be understood that the same principle applies to cases with other numbers of accommodating spaces, which will not be elaborated upon further below.

[0044] At least two domain function modules 102 are arranged in at least one layer of accommodating space and are used to respectively implement the domain functions of at least two domains of the vehicle. For example, in some embodiments, the at least two domain function modules 102 may be at least two of the domain function modules mentioned above, that is, the at least two domain function modules 102 include at least two of the following: powertrain domain function module, chassis domain function module, safety domain function module, cockpit domain function module, intelligent driving domain function module, and connectivity domain function module, as well as multi-domain auxiliary function module.

[0045] To address the high heat generated by the integration of multiple functional modules, a water-cooling assembly 103 according to an embodiment of this disclosure is arranged in at least one accommodating space. The water-cooling assembly 103 includes a pair of water-cooling plates 1031 and a heat-conducting component 1033. Each of the pair of water-cooling plates 1031 includes a tortuous flow channel 1032, and the tortuous flow channels 1032 in the pair of water-cooling plates 1031 are connected in series, such as... Figure 2 As shown. In some embodiments, the coolant in the tortuous flow channel 1032 can be circulated within the tortuous flow channel 1032 by a pumping element. The tortuous flow channels 1032 between a pair of water-cooled plates 1031 can be connected in series by pipes, so that the coolant can be circulated within the tortuous flow channels 1032 of the two cold plates by a set of pumping elements.

[0046] According to embodiments of the present disclosure, the heat-generating components 1021 of at least two domain functional modules 102 are respectively arranged on at least one side of a pair of water-cooled plates 1031, and the heat-conducting component 1033 is located between the water-cooled plate 1031 and the heat-generating component 1021 (e.g., a processor). In this way, the water-cooled plate 1031 can effectively dissipate heat for multiple domain control modules, thereby improving the stability and reliability of the domain controller 100.

[0047] The following will combine Figure 1 and Figure 2The specific structure of housing 101 is described. In some embodiments, housing 101 may include a first outer shell assembly 1011 and a first cover 1012. The first outer shell assembly 1011 includes a first bottom shell and a pair of first sidewalls extending from the first bottom shell toward a first side. The first cover 1012 is arranged to couple from the first side to the pair of first sidewalls of the first outer shell assembly 1011 to form a first receiving space in at least one layer of receiving space. The first receiving space is used to receive one of a pair of water-cooled plates 1031. Simultaneously, the first receiving space also receives portions of the domain function modules in at least two types of domain control modules 102.

[0048] For example, in some embodiments, multiple domain functional modules can be arranged on both sides of the first water-cooled plate 1031, and the corresponding heat-generating components 1021 are coupled to the water-cooled plate 1031 through the heat conduction components 1033 for effective heat dissipation and cooling.

[0049] In some embodiments, housing 101 further includes a second housing assembly 1013 and a second cover plate 1014. The second housing assembly 1013 includes a second bottom housing 1019 and a pair of second sidewalls 1010 extending from the second bottom housing 1019 toward a second side. The second bottom housing 1019 is coupled to a second side of the first bottom housing.

[0050] like Figure 3 As shown, the second housing assembly 1013 may have a support portion 1020. The support portion 1020 can support the domain controller 100 in a predetermined position when the domain controller 100 is placed horizontally, thereby facilitating the installation and fixation of the domain controller. In this document, when the domain controller 100 is placed horizontally, the first side may refer to the upper side, and the second side may refer to the lower side. Of course, it should be understood that when the domain controller adopts other installation or fixing orientations, the first side and the second side respectively refer to the orientations corresponding to the respective orientations, which will not be described in detail below.

[0051] The second cover 1014 is arranged to couple from a second side to a pair of second sidewalls 1010 of the second housing assembly 1013 to form a second receiving space for accommodating one of a pair of water-cooled plates 1031. Similar to the first receiving space, the second receiving space can also accommodate portions of the domain function modules from at least two domain control modules 102. For example, in some embodiments, multiple domain function modules 102 can be arranged on both sides of the second water-cooled plate 1031, and corresponding heat-generating components 1021 are coupled to the water-cooled plate 1031 via heat conduction components 1033 for effective heat dissipation and cooling.

[0052] As can be seen from the above description, at least two domain function modules 102 may include a plurality of domain function modules arranged in the first receiving space and located on the first side and the second side of the first water-cooled plate 1031, respectively; and a plurality of additional domain function modules arranged in the second receiving space and located on the first side and the second side of the second water-cooled plate 1031, respectively.

[0053] In some embodiments, housing 101 further includes a pair of first auxiliary cover plates 1015. The pair of first auxiliary cover plates 1015 are disposed between the first cover 1012 and the first bottom shell, and are respectively located between the ends of a pair of first sidewalls. The pair of first auxiliary cover plates 1015 includes a plurality of first clearance holes 1017 through which some connection ports of at least two domain functional modules 102 pass. These connection ports may include, but are not limited to: peripheral component fast interconnect (PCIe) bus ports, Ethernet ports, diagnostic ports (such as OBD-II), power ports, controller area network bus (CAN) ports, etc. These ports can be connected to corresponding data lines or power lines to connect to external devices or to other domain functional modules within the domain controller.

[0054] In some embodiments, housing 101 further includes a second auxiliary cover 1016. The second auxiliary cover 1016 is disposed between the second cover 1014 and the second bottom housing 1019, and is located between the ends of a pair of second sidewalls 1010, thereby sealing an opening between the ends of the pair of second sidewalls 1010. The second auxiliary cover 1016 includes a plurality of second clearance holes 1018 through which some connection ports of at least two domain functional modules pass. Similar to the first clearance holes 1017, these ports may include, but are not limited to: peripheral component fast interconnect (PCIe) bus ports, Ethernet ports, diagnostic ports (such as OBD-II), power ports, controller area network bus (CAN) ports, etc.

[0055] Furthermore, in some embodiments, at least one of the first side plates of a pair of first side plates, at least one of the second side plates of a pair of second side plates, and the portion of the first cover 1012 coupled to the pair of first side plates may include a plurality of third clearance holes through which partial connection ports of at least two domain functional modules 102 pass. In addition to providing clearance for the multiple ports mentioned above, the third clearance holes may also provide clearance for coolant inlets and outlets.

[0056] In some embodiments, to improve sealing performance, the first housing assembly 1011, the first cover 1012, and the pair of first auxiliary cover plates 1015, as well as the second housing assembly 1013, the second cover 1014, and the second auxiliary cover plate 1016, are sealed using at least one of a light-curing sealant, a natural-curing sealant, a sealing partition, and a sealing ring. Different sealing methods can be applied to appropriate locations to improve the overall sealing performance of the domain controller, while also enhancing anti-condensation performance.

[0057] For example, in some embodiments, the domain controller may include a pair of first sealing partitions and a second sealing partition. The pair of sealing partitions are respectively disposed inside a pair of first auxiliary cover plates 1015, and the second sealing partition is disposed inside a second auxiliary cover plate 1016. Light-curing sealant, natural-curing sealant, and / or sealing rings may be provided at other suitable locations between the first housing assembly 1011 and the first cover 1012, and between the second housing assembly 1013 and the second cover 1014, to further improve sealing performance.

[0058] For at least some of the domain functional modules 102, the domain controller may further include a damping component to improve vibration damping performance. This component is disposed between at least one of the first housing assembly 1011 and the second housing assembly 1013 and at least two domain functional modules. The damping component may include an elastic element, which can effectively reduce the risk of damage to some domain functional modules caused by the domain controller during vehicle bumps, further improving the reliability of the domain controller.

[0059] In some embodiments, such as Figure 4 As shown, the water-cooling assembly 103 also includes a vapor chamber 1036. The vapor chamber 1036, also known as a VC vapor chamber, is a high-efficiency thermal management component. Through rapid phase change cycling, it achieves rapid heat transfer and dissipation, effectively reducing localized overheating and maintaining uniform internal temperature. The vapor chamber 1036 is positioned between a pair of water-cooled plates 1031 and the heat-generating component 1021. The vapor chamber 1036 includes support columns arranged internally to support the internal cavity and capillary structures arranged within the internal cavity to facilitate heat transfer from the heat-generating component 1021 to the pair of water-cooled plates 1031 through the phase change of the fluid within the internal cavity.

[0060] By using the vapor chamber 1036, the heat-generating components 1021 of each domain functional module 102 in the domain controller, such as the arithmetic unit and the storage unit, can be effectively cooled, thereby improving the effectiveness of cooling and thus improving the reliability of the domain controller.

[0061] In some embodiments, to further improve the cooling effect, the water-cooled plate 1031 may also include heat dissipation fins 1034 arranged in the tortuous flow channel 1032, such as... Figure 5 As shown. The heat dissipation fins 1034 can be arranged at least in the tortuous flow channel 1032 at the position corresponding to the thermal coupling portion, thereby allowing the coolant to flow through it and increasing the heat dissipation area of ​​the coolant. The thermal coupling portion is the position where the heat-generating component 1021 is coupled to the water-cooled plate 1031 via the heat conduction component 1033 through the tortuous flow channel 1032. Of course, it should be understood that the heat dissipation fins 1034 can be arranged not only at the position corresponding to the thermal coupling portion, but also at any other position in the tortuous flow channel 1032.

[0062] In some embodiments, a thermoelectric cooler (TEC) may be provided between the heat-generating component 1021, where heat is more concentrated, such as between the thermal coupling portion of the integrated packaged SOC chip and the tortuous flow channel 1032. For example... Figure 6 As shown, for the SOC chip of the cockpit domain functional module, a TEC can be installed between it and the thermal coupling part. In this way, the chip surface temperature can be made much lower than the coolant temperature (in general liquid cooling, the chip surface temperature is higher than the coolant temperature), effectively reducing the chip temperature and improving the liquid cooling effect.

[0063] Furthermore, the solution according to the embodiments of this disclosure can also set the voltage applied to the thermoelectric cooler 1035 according to the temperature of the heating element 1021, thereby achieving adaptive adjustment of the temperature of the heating element 1021. Specifically, in some embodiments, the cooling device may 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 heating element 1021 coupled to the thermoelectric cooler 1035.

[0064] Embodiments of this disclosure also provide a vehicle. The vehicle includes the domain controller mentioned above. By using the domain controller according to embodiments of this disclosure, the performance and reliability of the vehicle can be improved.

[0065] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical applications, or technical improvements to the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
