Description

Technical Field

[0001] Embodiments of the present disclosure generally relate to the field of vehicles, and more particularly to a domain controller for a vehicle and a vehicle. Background Art

[0002] The domain controller in the vehicle is responsible for managing and coordinating multiple electronic control units (ECUs) in the vehicle to achieve efficient and intelligent vehicle control. In order to locate the vehicle, the domain controller may integrate a positioning module and auxiliary positioning modules such as IMU. In a conventional domain controller, the auxiliary positioning module is usually mounted on the printed circuit board (PCB) of the domain controller using surface mount technology (SMT). However, the domain controller generates a lot of heat during operation, and the high temperature environment may cause thermal expansion of the circuit board material, resulting in deformation or bending, as well as slight displacement between electronic components. For example, for a precision IMU, even a slight deformation may affect the performance of its internal sensitive components, thereby reducing the stability and accuracy of positioning.

[0030] The preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

The term "based on" means "based at least in part on". The terms "an example embodiment" and "an embodiment" mean "at least one example embodiment".

[0032] As mentioned above, in conventional domain controllers, the auxiliary positioning module is usually installed on the printed circuit board of the domain controller using surface mount technology. However, the domain controller generates a lot of heat during operation, and the high temperature environment may cause thermal expansion of the circuit board material, resulting in deformation or bending, as well as slight displacement between electronic components. For the precise auxiliary positioning module, even a slight deformation may affect the performance of its internal sensitive components, thereby reducing the stability and accuracy of positioning.

[0033] The embodiment of the present disclosure provides a domain controller 100 for a vehicle and a vehicle. In the domain controller 100, the auxiliary positioning module 50 is fixed on the inner wall of the box body 10, and the auxiliary positioning module 50 is separated from the circuit board 20. With this arrangement, the deformation of the circuit board 20 under high temperature or external force will not affect the auxiliary positioning module 50, and will not interfere with the performance of the sensitive components inside the auxiliary positioning module 50, thereby improving the stability and accuracy of positioning. Figure 1 to Figure 2 To describe the principles of the present disclosure in detail.

[0034] like Figure 1 and Figure 2 As shown, the domain controller 100 can integrate, process and distribute various information during the operation of the vehicle, and can efficiently and safely coordinate the operation of each subsystem to ensure the stable operation of the entire intelligent driving system. The domain controller 100 is a highly integrated and modular device, and at least includes a box body 10, a circuit board 20 and an auxiliary positioning module 50.

[0035] As the carrier of the domain controller 100, the structure of the box body 10 is not only related to aesthetics and protection, but also involves considerations such as heat dissipation management, electromagnetic compatibility (EMC) and mechanical strength. A receiving cavity 11 is provided in the box body 10. The size and shape of the receiving cavity 11 must be adapted to the circuit board 20 and other components inside it, while leaving enough space to ensure air circulation to reduce the internal temperature and thus extend the service life of the electronic components. The material selection of the box body 10 is also crucial. It must be lightweight to meet the needs of mobile devices, and must have sufficient durability and anti-interference capabilities.

[0036] In some embodiments, the box body 10 is a metal box body, such as stainless steel, copper, or copper-aluminum alloy. In this way, the metal material, especially stainless steel and copper alloy, has high strength and good corrosion resistance. Even in harsh environments, such as high temperature, humidity, or chemical corrosion, the metal box body can effectively protect the internal electronic components from damage, thereby ensuring the stable operation of the domain controller 100.

[0037] Secondly, metal has high rigidity and can withstand external impact and vibration without deformation. The vehicle will encounter various bumps and vibrations during driving. The solid metal box can prevent the internal circuit board 20 and components from being damaged by mechanical stress, ensuring the stability of the electronic system and the reliability of long-term operation.

[0038] Furthermore, metal is an excellent thermal conductor and can quickly absorb and disperse heat. Compared with other non-metallic materials, metal materials such as stainless steel, copper and copper-aluminum alloy have higher thermal conductivity, which can effectively transfer the heat generated by electronic components to the surface of the box body 10, and then dissipate it through natural convection or forced air cooling, thereby avoiding local overheating and reducing the impact of thermal stress on component performance.

[0039] In some alternative embodiments, the box body 10 may also be made of hard plastic or other non-metallic materials.

[0040] In the embodiment of the present disclosure, the circuit board 20 is the control center of the domain controller 100. The circuit board 20 integrates a variety of electronic components such as a processing unit, a memory, a communication interface, a power management module, etc., and can perform complex algorithm processing, such as data analysis, instruction decoding and execution, etc. The design of the circuit board 20 requires highly optimized wiring to ensure the efficiency and stability of signal transmission, while considering electrical isolation and noise suppression to maintain the purity of the signal. The circuit board 20 is installed in the accommodating cavity 11 and is coupled to the box body 10, for example, fixed to the box body 10 by riveting, welding, snaps, bolts, etc.

[0041] In some embodiments, the auxiliary positioning module 50 may be an inertial measurement unit (IMU). An inertial measurement unit is a device used to measure the three-axis attitude angle (or angular velocity) and acceleration of a vehicle, which can assist in the precise positioning of the vehicle. An IMU is equipped with a three-axis gyroscope and three-directional accelerometers to measure the angular velocity and acceleration of an object in three-dimensional space, and thereby calculate the attitude of the object.

[0042] In environments where there is no or insufficient global positioning system (GPS) signal (such as indoors, tunnels, deep valleys or between high-rise buildings), IMU can provide continuous motion tracking information to assist or independently perform navigation. When combined with GPS and other navigation systems, IMU can enhance positioning accuracy and stability. By measuring the angular velocity and acceleration of an object in different axes, IMU can calculate the object's attitude (such as pitch, roll and yaw angle) in real time.

[0043] In autonomous vehicles, IMU is an important component of the perception system. It helps the vehicle understand its own motion state and integrates with other sensor data to improve driving safety and path planning accuracy.

[0044] In some embodiments, the auxiliary positioning module may also include a satellite positioning element for detecting the location of the vehicle and generating location information, which may include a global positioning system (GPS), a Beidou navigation system, a GLONASS, etc.

[0045] The auxiliary positioning module 50 is installed in the accommodating cavity 11 and fixed on the inner wall of the box body 10. That is, the auxiliary positioning module 50 is separated from the circuit board 20. In this way, the influence of the deformation of the circuit board 20 due to high temperature on the sensitive gyroscope and accelerometer can be effectively avoided, and the measurement accuracy of the IMU is improved, and the stability and reliability are improved.

[0046] The auxiliary positioning module 50 is connected to the circuit board 20 through the circuit 30, and the position information can be transmitted to the processing unit on the circuit board 20 through the circuit 30. The transmission of the signal involves steps such as signal conditioning, analog-to-digital conversion (ADC), and data packet encapsulation to ensure the accuracy and efficient transmission of the data. After receiving the position information, the processing unit uses a complex algorithm to solve the raw data, eliminate errors, and finally output the precise position information of the vehicle.

[0047] In the intelligent transportation system, the application of the auxiliary positioning module 50 is far more than a simple positioning service. Combined with the powerful computing power of the processing unit, it can assist in realizing advanced functions such as real-time path planning, dynamic obstacle avoidance, and driving status monitoring. For example, in an autonomous driving scenario, the vehicle needs to make fast and accurate driving decisions based on real-time location information and map data, which also requires the auxiliary positioning module 50 to have a very high update rate and accuracy.

[0048] In some embodiments, Figure 1 and Figure 2 As shown, the circuit 30 includes a first interface portion 31 and a second interface portion 32. The first interface portion 31 is disposed on the auxiliary positioning module 50. The second interface portion 32 is disposed on the circuit board 20, and the second interface portion 32 is located on a side of the circuit board 20 facing the auxiliary positioning module 50, and the second interface portion 32 is coupled to the first interface portion 31.

[0049] like Figure 1 and Figure 2 As shown, the first interface portion 31 and the second interface portion 32 are interfaces in the circuit 30 for connecting different components, and may be plugs, sockets, pins, solder joints or any suitable connection method, in order to ensure the transmission of electronic signals or power.

[0050] The first interface part 31 is mounted on the auxiliary positioning module 50, or the first interface part 31 is a part of the auxiliary positioning module 50. Coupling here refers to physical or electrical connection, ensuring that the auxiliary positioning module 50 can receive or send necessary signals to the circuit 30 through the first interface part 31. The second interface part 32 is mounted on the circuit board 20, and the second interface part 32 is located on the side facing or close to the auxiliary positioning module 50, which helps to improve space utilization and signal transmission efficiency, and can reduce mutual interference between modules.

[0051] A circuit 30 for electrically connecting the first interface portion 31 and the second interface portion 32 may be provided between the two. That is, the auxiliary positioning module 50 is connected to the second interface portion 32 through the first interface portion 31, and then connected to a wider circuit system on the circuit board 20, so that the auxiliary positioning module 50 can exchange data with other components in the system, such as a processing unit, through the circuit board 20 to realize the processing and utilization of the vehicle location information.

[0052] In some embodiments, the first interface portion 31 may also be directly plugged into or directly coupled to the second interface portion 32 in other appropriate ways. In this way, by direct plugging, additional components are eliminated, which not only reduces costs but also reduces the risk of failure introduced by increasing connection points. Secondly, direct connection reduces assembly steps, making installation more efficient. Without the need for professional tools or complex operating instructions, even non-professionals may easily complete the connection, saving time and training costs. Furthermore, direct plugging reduces the probability of short circuits, open circuits or other electrical problems caused by miswiring, and improves the stability and safety of the system.

[0053] In some alternative embodiments, such as Figure 1 and Figure 2 As shown, the circuit 30 further includes a flexible circuit 33. The flexible circuit 33 is placed in the accommodating cavity 11, and the flexible circuit 33 includes a first end and a second end. The first end of the flexible circuit 33 is coupled to the first interface portion 31, and the second end of the flexible circuit 33 is coupled to the second interface portion 32.

[0054] like Figure 1 and Figure 2As shown, in some embodiments, the flexible circuit 33 can be a circuit 30 made of a flexible material (such as a polyimide film), which can be bent and folded without affecting its electrical performance, and is suitable for use in an environment where space is limited or dynamic changes are required. The flexible circuit 33 is placed in the accommodating cavity 11, which can protect the flexible circuit 33 from external damage. The flexible circuit 33 is connected to the first interface portion 31 and the second interface portion 32 at its two ends, which not only ensures the transmission of signals or power, but also maintains the flexible arrangement of the circuit. In this way, the auxiliary positioning module 50 is no longer restricted by the fixed wiring position and can be flexibly installed in any suitable position in the box body 10. The flexible circuit 33 can make the layout of the auxiliary positioning module 50 in the accommodating cavity 11 more flexible, help improve space utilization, simplify the assembly process, and at the same time improve heat dissipation conditions and reduce electromagnetic interference and other problems.

[0055] In some embodiments, Figure 1 As shown, a positioning structure 40 is provided on the inner side wall of the box body 10 , and the positioning structure 40 is used to limit and fix the position of the auxiliary positioning module 50 .

[0056] like Figure 1 As shown, the positioning structure 40 is usually composed of protrusions, grooves, pin holes, magnetic points, screw holes, etc., and the specific form depends on the application requirements. The main function of the positioning structure 40 is to ensure that the auxiliary positioning module 50 can be accurately placed in the predetermined position in the box body 10 and fixed, which can prevent the auxiliary positioning module 50 from being offset due to vibration, movement or other external factors during use, and ensure the normal function of its function.

[0057] Thanks to the positioning structure 40, when installing the auxiliary positioning module 50, the assembly workers or automated equipment do not need to spend extra time to align or adjust the position, and can directly complete the installation quickly according to the preset guide, thereby improving the efficiency of the production or maintenance process. At the same time, by limiting the movement of the auxiliary positioning module 50, the positioning structure 40 enhances the stability of the auxiliary positioning module 50 in the working state. When the vehicle is driving, it will encounter various road conditions, which may cause severe vibrations. The positioning structure 40 can effectively absorb or resist these vibrations and reduce the impact of external shocks, thereby ensuring that the auxiliary positioning module 50 can still work stably when the vehicle is bumpy, without affecting the accuracy of its navigation function.

[0058] In some embodiments, Figure 2 As shown, the positioning structure 40 includes a first limiting rib 41 and a second limiting rib 42 intersecting each other. The first limiting rib 41 and the second limiting rib 42 respectively abut against the outer side wall of the auxiliary positioning module 50 to provide positioning for the auxiliary positioning module 50.

[0059] like Figure 2As shown, the first limiting rib 41 and the second limiting rib 42 form a cross structure. The first limiting rib 41 and the second limiting rib 42 realize the positioning function by directly contacting the side of the shell of the auxiliary positioning module 50. When the outer side wall of the auxiliary positioning module 50 is completely aligned and in contact with the two ribs, the auxiliary positioning module 50 is in the correct position. In this way, not only can the assembly process be simplified, but also the stability of the auxiliary positioning module 50 can be ensured.

[0060] In some embodiments, the auxiliary positioning module 50 includes a positioning unit and a shell. The positioning unit can be the IMU mentioned above. The shell is arranged on the outside of the positioning unit, and the shell is fixed to the inner wall of the box body 10. The shell is an external protective structure of the positioning unit, and its function is to provide physical protection for the sensitive positioning unit to prevent environmental factors such as dust, moisture, impact, etc. from damaging the positioning unit. The shell is installed on the inner wall of the box body 10 by means of screws, buckles or adhesives, which can ensure that the auxiliary positioning module 50 remains stable during use and will not be displaced due to vibration or movement.

[0061] In some embodiments, Figure 1 and Figure 2 As shown, the housing is detachably fixed to the inner wall of the box body 10. In this way, the auxiliary positioning module 50 can be quickly installed and removed, which helps to improve the assembly efficiency of the auxiliary positioning module 50, and the auxiliary positioning module 50 can be replaced in time when a failure occurs.

[0062] In some embodiments, Figure 1 and Figure 2 As shown, the shell includes a plurality of first screw holes 51, and the inner side wall of the box body 10 includes a plurality of second screw holes. The plurality of first screw holes 51 are connected to the plurality of second screw holes one by one through bolts.

[0063] like Figure 1 and Figure 2 As shown, the housing is provided with a plurality of first screw holes 51 at its appropriate position, and the first screw holes 51 are set according to a certain layout and spacing to ensure the stability and alignment of the connection. The inner wall surface of the box body 10 is also provided with screw holes of corresponding number and layout, which are called second screw holes, and the second screw holes match the first screw holes 51 on the housing. In order to firmly mount the housing to the inner side of the box body 10, each first screw hole 51 is connected with a corresponding second screw hole on the box body 10 by bolts. For example, a bolt is inserted from one side of the housing (through the first screw hole 51), then passed through the corresponding second screw hole of the box body 10, and fastened with a nut on the other side, thereby realizing a rigid connection between the two components.

[0064] In some embodiments, the shell of the auxiliary positioning module 50 can be a metal shell. In this way, the metal shell has a large rigidity and the shell is not easy to deform or twist. Under conditions such as vibration, impact or temperature change, the metal shell can better maintain its original shape. The rigidity of the metal shell can effectively constrain the positioning unit to prevent it from unnecessary deformation due to external forces or environmental factors, thereby maintaining the stability and positioning accuracy of the positioning unit. Secondly, metal is a good thermal conductor. Compared with insulating materials such as plastics, the metal shell can transfer the heat generated by the internal positioning unit to the shell surface more quickly, and then further dissipate it into the surrounding environment. The positioning unit is sensitive to temperature, and too high an operating temperature may cause measurement errors. Therefore, the heat dissipation capacity of the metal shell helps to maintain a suitable operating temperature, protect the positioning unit from interference from heat sources, and ensure its stable operation.

[0065] In some embodiments, a ceramic packaging structure is provided between the positioning unit and the housing. In this way, the ceramic packaging structure can maintain the position and shape of the positioning unit in the housing, avoid interference of temperature or external force on the positioning unit, and prevent the positioning unit from being deformed unnecessarily due to external force or environmental factors, thereby maintaining the stability and positioning accuracy of the positioning unit.

[0066] In some embodiments, Figure 1 and Figure 2 As shown, the auxiliary positioning module 50 is installed in the box body 10 at a position corresponding to the end of the circuit board 20 . At this time, the auxiliary positioning module 50 can be away from the heat source on the circuit board 20 .

[0067] like Figure 1 and Figure 2 As shown, the auxiliary positioning module 50 is installed at one end of the circuit board 20. When the domain controller 100 is working, there are often some heat generating components on the circuit board 20, such as a processor (CPU), a power management module, a high-power transistor, etc. The auxiliary positioning module 50 is installed at a location away from these heat sources in order to reduce the impact of the heat source on the performance of the auxiliary positioning module 50. Therefore, by physically staying away from the heat source, the auxiliary positioning module 50 can be protected to ensure that its stability and positioning accuracy are as little affected by the heat effect as possible.

[0068] In a second aspect of the present disclosure, a vehicle is provided, comprising a vehicle body and a domain controller 100 according to the first aspect of the present disclosure, wherein the domain controller 100 is coupled to the vehicle body.

[0069] In the domain controller 100 of the vehicle, the circuit board 20 and the auxiliary positioning module 50 are separated. The deformation of the circuit board 20 under high temperature or external force will not affect the auxiliary positioning module 50, and will not interfere with the performance of sensitive components inside the auxiliary positioning module 50, thereby improving the stability and accuracy of positioning.

[0070] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or technical improvements in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
