Description

Technical Field

[0001] This application relates to the field of automotive engine compartments, and more specifically, to the layout structure, installation method, and vehicle of an intelligent domain controller for autonomous vehicles. Background Technology

[0002] As autonomous vehicles become more widespread, the market share of intelligent driving vehicles is also increasing. Intelligent driving will be a crucial technology for solving traffic congestion in the future, significantly improving both production and transportation efficiency. With the popularization of intelligent driving, traffic congestion will no longer be a problem; people will be more accepting of longer commutes, and cars will become a natural extension of home and office, further facilitating new urbanization.

[0003] From a technological trend perspective, the autonomous driving industry is seeking a new architecture that can meet the following needs: reducing electronic and electrical complexity, improving the efficiency of electronic and electrical architecture, increasing the efficiency of the final assembly line, enabling faster development and iteration, decoupling software and hardware, and improving the end-user experience. From this perspective, the next generation of autonomous driving systems tends to achieve a unified architecture by shifting from a distributed process to a centralized process.

[0004] The implementation of a centralized domain controller solution is not a simple process, primarily due to the presence of numerous actuator units within the vehicle body itself. These include the autonomous driving domain, the intelligent cockpit domain, the intelligent chassis domain, and the original body control unit. Therefore, before truly achieving a centralized control solution with large domain control, autonomous driving systems will introduce various controllers, such as intelligent cockpit domain controllers and intelligent chassis domain controllers, in stages. The purpose of this division is to break down existing functional boundaries, allowing for the creation of regional controllers, thereby facilitating the transformation from a functional domain architecture to a centralized vehicle architecture.

[0005] The intelligent domain controller assembly in the front cabin of an autonomous vehicle needs to integrate advanced sensors, controllers, and actuators. While maintaining the vehicle's dimensions, this presents challenges to space utilization and weight reduction, increasing the difficulty of developing and deploying intelligent vehicles. The numerous additional controllers, actuators, and mounting brackets increase the vehicle's cost and weight. Therefore, a redesign of the existing front cabin internal structure is necessary for autonomous vehicles. Summary of the Invention

Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to limit the application.

[0047] It should be understood that although the terms first, second, third, etc., may be used in the embodiments of this application, these descriptions should not be limited to these terms. These terms are only used to distinguish the descriptions. For example, first may also be referred to as second without departing from the scope of the embodiments of this application, and similarly, second may also be referred to as first.

[0048] Depending on the context, the words “if” or “suppose” as used here can be interpreted as “when” or “in response to determination” or “in response to detection.” Similarly, depending on the context, the phrases “if determination” or “if detection (of the stated condition or event)” can be interpreted as “when determination” or “in response to determination” or “when detection (of the stated condition or event)” or “in response to detection (of the stated condition or event).”

[0050] It should be noted that any symbols and / or numbers present in the specification that are not marked in the accompanying drawings are not reference numerals.

[0051] Because there are many parts in the engine compartment and the space is limited, the many parts in the engine compartment are fixed by screwing them to the body with independent metal brackets. This fixing method requires a lot of space and wastes space resources.

[0052] To address the aforementioned technical problems, this application provides an arrangement structure for an intelligent domain controller for an autonomous vehicle in one specific embodiment, which is described below in conjunction with... Figure 1 The embodiments of this application will be described in detail.

[0053] According to a specific embodiment of this application, this application provides an arrangement structure for an intelligent domain controller for an autonomous vehicle, which includes a mounting bracket 1, an intelligent domain controller assembly 6, a transfer power distribution box assembly 10, and a low-voltage wiring harness 14. For example... Figure 1 As shown, the mounting bracket 1 has a first side close to the front engine compartment 9 of the vehicle body and a second side opposite to it. The first side is provided with a plurality of first mounting members 4 and a plurality of second mounting members 8, and the second side is provided with a plurality of third mounting members 2 and a plurality of fourth mounting members 3.

[0054] like Figure 2 As shown, the intelligent domain controller assembly 6 is fixed to the first side via the first mounting member 4 to form a bracket assembly consisting of the intelligent domain controller assembly 6 and the mounting bracket 1. The bracket assembly is fixed to the side of the front engine compartment 9 of the vehicle body via the second mounting member 8 (e.g., Figure 3 (As shown).

[0055] like Figure 4 As shown, the transfer distribution box assembly 10 and the low-voltage wiring harness 14 are fixed to the second side by the third mounting component 2 and the fourth mounting component 3, respectively.

[0056] The layout scheme provided in this embodiment uses only one mounting bracket 1 to fundamentally fix the intelligent domain controller assembly 6, the transfer power distribution box assembly 10, the power distribution isolation assembly, and the low-voltage wiring harness 14. Through the engine compartment layout scheme of the intelligent domain controller provided by this invention, multiple systems and components in the engine compartment can be integrated and fixed. Within a limited space, the layout structure provided in this application allows for the installation of electrical components such as the intelligent domain controller assembly 6, the transfer power distribution box assembly 10, and the low-voltage wiring harness 14 within a very small engine compartment space. Compared with previous separately arranged schemes, the layout structure provided in this embodiment is simple, greatly reducing the complexity of the manufacturing process and avoiding the use of complex and heavy frame structures. It meets the process requirements for assembly and maintenance, making the vehicle compact and convenient, significantly reducing the number of vehicle parts and the overall vehicle weight, while also achieving the goal of reducing fuel consumption.

[0057] In addition, electrical components such as the intelligent domain controller assembly 6, the transfer distribution box assembly 10, and the low-voltage wiring harness 14 are fixed on different sides of the mounting bracket 1, realizing the compact layout of various electrical components that are dispersed, improving space utilization and the installation strength of each electrical component. Various electrical components can be pre-assembled onto the mounting bracket 1 and then uniformly installed in the engine compartment, improving assembly efficiency.

[0058] It should be noted that this embodiment does not impose specific requirements or special limitations on the structure of electrical components such as the intelligent domain controller assembly 6, the transfer distribution box assembly 10, and the low-voltage wiring harness 14. All relevant electrical components disclosed in the prior art can adopt the arrangement structure provided in this embodiment, and can achieve the same technical effects as this embodiment.

[0059] To help those skilled in the art better understand the technical solution of the present invention, the following is a brief, exemplary description of the structure and function of the intelligent domain controller assembly 6:

[0060] With the increasing electrification of automobiles and the explosive growth of automotive software systems, the number of sensors and control units has increased rapidly, leading to a decline in overall vehicle performance and more complex wiring. Therefore, electrical architecture solutions based on the Intelligent Domain Controller Assembly 6 (IDA6) are gradually replacing distributed architectures. Utilizing multiple "central brains" to control vehicle sensors has become a better solution, and IDA6 achieves these functions. The vehicle is divided into intelligent driving domain controllers, chassis domains, and powertrain domains based on its automotive electronic components. Each domain is controlled relatively centrally using chips with higher processing power. Centralized control strategies effectively reduce the number of controllers, lower overall vehicle controller costs, reduce vehicle weight, and achieve centralized and coordinated control of different sensors, such as the integration of high-voltage management, energy management, thermal management, and torque management functions, thereby improving energy efficiency.

[0061] As mentioned above, the intelligent domain controller assembly 6 mainly consists of three parts: the intelligent driving domain controller, the chassis domain controller, and the power domain controller.

[0062] The main functional modules of the intelligent driving domain controller include: Adaptive Cruise Control (ACC), Automatic Emergency Braking (AEB), Lane Keeping Assist (LKA), Lane Departure Warning (LDW), and Automatic Parking Assist (APA).

[0063] The main functional modules of the chassis domain controller are: Combined Braking System (CBS), Electronic Parking Brake (EPB), Electronic Stability Control (ESC), and Electric Power Steering (EPS). Among them, CBS, EPB, and ESC are the controllers of the chassis domain braking actuators, and EPS is the controller of the chassis domain steering actuators.

[0064] The intelligent driving domain controller and the chassis domain controller are connected via a gateway. The intelligent driving domain controller interacts with the chassis domain controller through the chassis control interface to control the vehicle's braking and steering functions. Control commands from the intelligent driving domain controller are sent to the gateway through the chassis control interface, and the gateway forwards the control commands to the chassis domain controller.

[0065] The main functional modules of the power domain controller include: a high-voltage management control module, an energy management control module, a thermal management control module, and a torque management control module. The high-voltage management control module manages high voltage, including high-voltage power-on / off control for the electric vehicle, power system activation / deactivation control, high-voltage safety, and high-voltage charging / discharging. The energy management control module manages energy, including high-voltage energy balance, power limiting for electrical accessories and the power system, and energy recovery. The thermal management control module manages thermal energy, including passenger compartment heating / cooling energy supply, motor cooling, high-voltage controller cooling, and battery heating / cooling. The torque management control module manages torque, including external torque intervention, torque arbitration, maximum torque capacity calculation, and torque flow control.

[0066] Furthermore, the braking function module of the chassis domain controller can be separated from the chassis domain and deployed to the intelligent driving domain controller. The control function module of the intelligent driving domain controller sends control commands to the braking function module through internal signal interaction, realizing the braking control function of the chassis domain. The intelligent domain controller assembly 6 provided in this embodiment enables the control function module of the intelligent driving domain controller and the braking function module of the chassis domain controller to achieve signal interaction within the intelligent driving domain controller, without the need for gateway forwarding, reducing the risk of functional failure due to time delay and improving vehicle driving safety.

[0067] Furthermore, the steering function module of the chassis domain controller can be separated from the chassis domain and deployed to the intelligent driving domain controller to realize the steering control function of the chassis domain. In addition, since the signal interaction between modules is internal to the intelligent driving domain controller, the number of signals on the bus is reduced, alleviating the load pressure on the bus; and the response priority of each actuator control command can be uniformly managed within the intelligent driving domain controller, avoiding low-priority control commands occupying the execution time of high-priority control commands. Moreover, the intelligent driving control function can be integrated with the chassis control function in the intelligent domain controller assembly 6, which can reduce redundant design in software control, reduce code volume, facilitate the coordinated software development and debugging of the intelligent driving control layer and the actuator control layer, and improve the overall vehicle control performance.

[0068] Similarly, to assist those skilled in the art in better understanding the technical solution of the present invention, the structure and function of the transfer distribution box assembly 10 are briefly described below by way of example:

[0069] The transfer power distribution box assembly 10 is a high-voltage, high-current distribution unit for autonomous vehicles. It adopts a centralized power distribution scheme. Depending on the system architecture requirements of different customers, the transfer power distribution box assembly 10 also integrates some battery management system intelligent control management units.

[0070] Specifically, the transfer distribution box assembly 10 includes a box body and various power distribution components located inside the box body. The power distribution components mainly include a DC power distribution module, a control module, and an auxiliary power supply module. The DC power distribution module has an overload protection self-recovery function and can provide short-circuit and overcurrent protection for each power branch according to the load conditions of each electrical equipment branch. Its input terminal is connected to the power supply module and a linear voltage regulator, and its output terminal is connected to the dedicated equipment power system. The control module is connected to each electrical equipment to monitor the operating status of each electrical equipment and control its operation. The auxiliary power supply module can provide auxiliary power to each electrical equipment.

[0071] The enclosure contains a positive copper busbar, an insulating plate, and a negative copper busbar. The positive copper busbar is connected to the negative copper busbar via the insulating plate, which divides the interior of the enclosure into upper and lower spaces. The DC power distribution module is located in the upper space, while the control module and auxiliary power module are located in the lower space. This layered arrangement of different power distribution components makes the product structure more compact. While ensuring the normal operation of each component, sufficient heat dissipation space is provided between them, allowing the heat generated during operation to be promptly transferred away through the enclosure, thereby extending the service life of the power distribution components.

[0072] In some embodiments, the system also includes a power distribution isolator assembly 11 and an auxiliary bracket 13, with the transfer distribution box assembly 10 snapped into and fixed to the power distribution isolator assembly 11.

[0073] The auxiliary bracket 13 is equipped with multiple fifth mounting parts 12. The power distribution isolator assembly 11 is fixed to the auxiliary bracket 13 through the fifth mounting parts 12 to form an advanced transfer power distribution box assembly 10 consisting of the transfer power distribution box assembly 10, the power distribution isolator assembly 11 and the auxiliary bracket 13.

[0074] The second side of the mounting bracket 1 is also equipped with multiple sixth mounting parts 5, and the advanced transfer distribution box assembly 10 is fixed to the second side by the sixth mounting parts 5.

[0075] The layout structure provided in this embodiment solves the problems of insufficient space and disorganized layout in the front engine compartment of autonomous vehicles. By integrating the intelligent domain controller assembly 6, the intermediate power distribution box assembly 10, and the low-voltage wiring harness 14 together, and forming a powertrain with the mounting bracket 1, the complex assembly problem in the front engine compartment of autonomous vehicles is effectively solved. For high-level autonomous driving models, the power distribution isolator assembly 11 and the intermediate power distribution box assembly 10 can be pre-assembled and integrated using the auxiliary bracket 13. After integrated installation, they can be assembled as a whole in the mounting bracket 1, improving the assemblability and ease of disassembly in the front engine compartment of autonomous vehicles. In addition, the effective and reasonable arrangement of components such as the intermediate power distribution box assembly 10 and the intelligent domain controller assembly 6 through high and low voltage connectors and wiring harnesses can effectively reduce electromagnetic interference and improve the stability of the entire vehicle.

[0076] It should be noted that this embodiment does not impose specific requirements or special limitations on the structure of the power distribution isolator assembly 11. The power distribution isolator assemblies 11 disclosed in the prior art can all adopt the arrangement structure provided in this embodiment, and can also achieve the technical effects that this embodiment can achieve.

[0077] To help those skilled in the art better understand the technical solution of the present invention, the structure and function of the power distribution isolator assembly 11 are briefly described below by way of example:

[0078] The power distribution isolator assembly 11 includes a power supply circuit, a power distribution isolation circuit, and a signal output circuit. The power supply circuit provides power to the power distribution isolation circuit and the signal output circuit. The power distribution isolation circuit has an isolation positive terminal and an isolation negative terminal. When an external input signal is connected to the isolation positive terminal and the isolation negative terminal, the power distribution isolator assembly 11 performs the function of an isolator.

[0079] In some embodiments, such as Figure 5 As shown, a snap-fit ​​structure 15 is also provided on the second side, and the low-voltage wire harness 14 is fixed to the second side through the snap-fit ​​structure 15 and the fourth mounting piece 3.

[0080] In some embodiments, the two ends of the upper edge of the second side extend vertically toward the front engine compartment 9 of the vehicle body to form two mounting plates, and a seventh mounting member 7 is disposed on each mounting plate, and the mounting bracket 1 is fixed to the front engine compartment 9 of the vehicle body by means of the seventh mounting member 7.

[0081] In some embodiments, the number of first mounting members 4 is four, located at the four vertex regions of the mounting bracket 1 respectively.

[0082] There are two second mounting parts 8, located at both ends of the lower edge of the second side, which cooperate with the seventh mounting part 7 to fix the mounting bracket 1 to the front engine compartment 9 of the vehicle body.

[0083] There are two third mounting pieces 2, which are symmetrically arranged in the upper half of the two vertical edges on the second side.

[0084] The fourth mounting piece 3 is one in number, located at the bottom area of ​​the vertical edge on the second side.

[0085] There are four fifth mounting components 12, located at the four vertices of the auxiliary bracket 13.

[0086] There are four sixth mounting pieces 5. Two sixth mounting pieces 5 are arranged symmetrically in a group at the two vertical edges of the second side. One sixth mounting piece 5 in the same group is located at the vertex region of the upper edge of the second side, and the other sixth mounting piece 5 is located in the middle region of the vertical edge of the second side.

[0087] A third mounting component 2 is located between the two sixth mounting components 5 in the same group.

[0088] In some embodiments, the mounting bracket 1 is a stamped part made of galvanized steel, and the first mounting part 4, the second mounting part 8, the third mounting part 2, the fourth mounting part 3, the sixth mounting part 5 and the seventh mounting part 7 are all studs fixed on the mounting bracket 1; the fifth mounting part 12 is a stud fixed on the auxiliary bracket 13.

[0089] The mounting bracket 1 in the cabin layout scheme provided in this embodiment is a stamped part made of galvanized steel. Multiple studs are welded on the mounting bracket 1 as mounting parts. Through the cooperation between multiple planes, the integrated fixing function can be achieved, while increasing the structural strength of the bracket and reducing the overall weight.

[0090] According to another specific embodiment of this application, this application provides an installation method for an intelligent domain controller assembly 6 for an autonomous vehicle, the installation method comprising:

[0091] In an interior work station, the intelligent domain controller assembly 6 is fixed to the first side of the mounting bracket 1 via the first mounting component 4 to form a bracket assembly;

[0092] The bracket assembly is fixed to the side of the front engine compartment 9 of the vehicle body via the second mounting component 8;

[0093] The intermediate distribution box assembly 10 and the low-voltage wiring harness 14 are respectively fixed to the second side of the mounting bracket 1 by the third mounting component 2 and the fourth mounting component 3;

[0094] Among them, the intermediate power distribution box assembly 10 adopts different installation schemes according to different levels of autonomous driving models.

[0095] In some embodiments, in a primary interior work station of a high-level autonomous driving vehicle, the intermediate power distribution box assembly 10 is installed as follows:

[0096] The transfer distribution box assembly 10 is snapped and fixed to the distribution isolator assembly 11; the distribution isolator assembly 11 is fixed to the auxiliary bracket 13 by the fifth mounting part 12 to form the advanced transfer distribution box assembly 10; the advanced transfer distribution box assembly 10 is fixed to the second side of the mounting bracket 1 by the sixth mounting part 5.

[0097] In some embodiments, in a low-level autonomous driving vehicle's interior work station, the transfer power distribution box assembly 10 is installed by directly fixing the transfer power distribution box assembly 10 to the second side of the mounting bracket 1 via the third mounting component 2.

[0098] The mounting bracket 1 used in this invention can achieve integrated fixing functions on both high-level and low-level autonomous driving vehicles. It has a high degree of integration, wide applicability, greatly reduces the number of parts, reduces the weight of the whole vehicle, saves the cost of the whole vehicle, and reduces design and assembly time.

[0099] In high-level autonomous driving vehicles, the power distribution isolator assembly 11 and the intermediate power distribution box assembly 10 are pre-assembled and integrated using an auxiliary bracket 13 to obtain an advanced intermediate power distribution box assembly 10. The advanced intermediate power distribution box assembly 10 is then integrated and assembled onto the mounting bracket 1 as a whole using the sixth mounting component 5.

[0100] In low-level autonomous driving vehicles, since there is no power distribution isolator assembly 11, there is no need for the auxiliary bracket 13 to be installed on the base. The transfer power distribution box assembly 10 can be directly fixed to the mounting bracket 1 through the third mounting part 2 without affecting the installation of other parts, thus achieving maximum versatility in the engine compartment layout.

[0101] According to another specific embodiment of this application, this application provides a vehicle, the vehicle including a front engine compartment 9 and a mounting bracket 1, an intelligent domain controller assembly 6, a transfer power distribution box assembly 10 and a low-voltage wiring harness 14 fixed to the side of the front engine compartment 9.

[0102] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
