[0029] To meet the compatibility and scalability requirements of vehicle EEA, embodiments of this disclosure provide an integrated electronic and electrical system, such as... Figure 1 The diagram shows the structure of the integrated electronic and electrical system. This integrated electronic and electrical system includes a Central Control Unit (CCU) 10; the Central Control Unit 10 includes a body control module 101, a basic cockpit module 102, and an intelligent driver assistance module 103, the intelligent driver assistance module 103 being used to implement Level 2 intelligent driver assistance functions; the Central Control Unit 10 is provided with function expansion reserved resources 104, which are used to expand cockpit functions and / or intelligent driving functions.
[0030] The integrated electronic and electrical system uses a central integrated domain controller 10 as its base. The central integrated domain controller 10 highly integrates the body control module 101, the basic cockpit module 102, and the intelligent driver assistance module 103, thereby highly integrating body control, basic cockpit, and intelligent driver assistance. The central integrated domain controller 10 is equipped with function expansion reserved resources 104 to reserve resources for expanding cockpit functions and / or intelligent driving functions, and to support cockpit function upgrades and / or intelligent driving assistance function upgrades, thus meeting the vehicle's EEA expansion and compatibility requirements.
[0031] In the exemplary embodiment, the central integrated domain controller 10 is implemented using a high-performance in-vehicle cross-domain computing chip. This chip possesses powerful computing capabilities, rich communication interfaces, multimedia processing capabilities, and storage-related functions. It also includes various safety subsystems and real-time subsystems. For example, this high-performance in-vehicle cross-domain computing chip is implemented using the C1296, featuring a quad-core CPU capable of handling complex computing tasks and ensuring system operational security and real-time performance. It has multiple communication interfaces such as CAN, Ethernet (Eth), and SPI. The CAN interface can be used for bus communication in scenarios such as inside a vehicle, enabling data interaction between modules. The Ethernet interface allows for high-speed data transmission. The SPI interface can be used for serial communication between the chip and other devices, facilitating the connection of various sensors and peripherals. It also has audio and video processing capabilities for multimedia playback applications and storage-related interfaces such as eMMC, which can be used to connect external storage devices for data storage and retrieval.
[0032] A centrally integrated domain controller can be implemented based on a single high-performance cross-domain computing chip, or it can be built upon this single high-performance cross-domain computing chip by adding other chips to increase computing power and interface resources. The specific expansion method is designed according to needs. For example, using the C1296 chip as the main processing chip, an MCU can be added as a resource expansion chip to supplement the main processing chip with computing power and interface resources. The MCU and the C1296 chip exchange data through interfaces such as SPI and RGMII. In addition, other data conversion modules can be added as needed to expand peripherals. For example, the SW88Q5152 chip can be used to connect the data between the C1296 chip and the MCU chip, enabling the conversion to data that supports EthPy interfaces.
[0033] For example, the central integrated domain controller 10 has redundant resources capable of supporting L3 and above advanced autonomous driving.
[0034] In an exemplary embodiment, such as Figure 2The diagram shows the structure of the central integrated domain controller. The central integrated domain controller 10 connects to 12 cameras, 5 millimeter-wave radars, and 12 ultrasonic radar sensors, thus providing sufficient data to support Level 2 autonomous driving functions. The 12 cameras include a front surround-view camera, a rear surround-view fisheye camera, a left surround-view fisheye camera, and a right surround-view fisheye camera; front camera 1; front camera 2; left front camera; right front camera; rear camera; right rear camera; left rear camera; and a driver monitoring camera. The central integrated domain controller connects to the 12 cameras through several data processing and conversion modules (DES). The cameras and DES modules are connected via a high-speed serial interface (GMSL2) based on SerDES (serializer / deserializer). Each DES module, in addition to connecting to the cameras, also reserves communication resources (such as a data sharing interface) for sharing camera data when expanding autonomous driving functions.
[0035] The system includes five millimeter-wave radars: a forward-facing millimeter-wave radar, a left-front millimeter-wave radar, a left-rear millimeter-wave radar, and a right-rear millimeter-wave radar. These five radars are connected to the central integrated domain controller via a CAN interface. The CAN interface also reserves communication resources for sharing millimeter-wave radar data when expanding intelligent driving functions. The system also includes twelve ultrasonic radars connected to the central integrated domain controller via several distributed system interfaces (DSI3), for example, six ultrasonic radars forming a group, corresponding to one DSI3.
[0036] In the exemplary embodiment, the vehicle body control module 101 is used to realize comfort, convenience and safety functions related to the vehicle body, specifically including functions such as windows, sunroof, windshield wipers, electric rearview mirrors, door lighting, key remote control, electric tailgate, power management, and communication.
[0037] The basic cockpit module 102 is used to realize core interactions and basic experiences. Its core functions include human-machine interaction, basic infotainment, basic vehicle control, communication, and linkage. For example, the basic cockpit module 102 is used to implement, but is not limited to, instrument cluster software (QNX) and data display, 360-degree surround view, augmented reality head-up display (ARHUD), diagnostics, signal processing, and other automotive safety integrity level B (ASIL-B) functions. The basic cockpit module 102 outputs instrument cluster data, HUD data, audio and video codec data, connects to an amplifier (AMP) for audio data amplification, armrest screen data, Bluetooth data, USB data, etc.
[0038] The intelligent assisted driving module 103 is used to realize L2 level intelligent assisted driving functions, including adaptive cruise control, lane keeping assist, traffic jam assist, automatic emergency braking, blind spot detection, driver monitoring system, automatic parking, intelligent high beam control, traffic sign recognition, rear cross traffic alert, etc. L2 level intelligent assisted driving functions have high environmental requirements (may fail in bad weather or complex road conditions), the system reaction speed is limited (driver intervention is still required if there is a sudden cut-off), and the driver is always the main responsible party for safety (the driver must remain alert, keep both hands on the steering wheel, and clean the sensors / check the system status regularly).
[0039] In some embodiments, such as Figure 3 The diagram shows a structural schematic of the extended cockpit functionality. The function extension reserved resource 104 includes a cockpit function extension reserved interface 1041 for expanding cockpit functionality. The integrated electronic and electrical system also includes an intelligent cockpit controller 20, which is connected to the central integrated domain controller 10 via the cockpit function extension reserved interface 1041. The intelligent cockpit controller is used to implement the extended cockpit functionality. By extending the intelligent cockpit controller 20, the intelligent cockpit functionality of the integrated electronic and electrical architecture can be upgraded. Furthermore, the central integrated domain controller 10, based on the function extension reserved resource 104, has the capability to further upgrade intelligent assisted driving functions.
[0040] For example, the cockpit function expansion reserved interface 1041 includes a cockpit control communication interface and a basic cockpit data sharing interface. The cockpit control communication interface is used for the intelligent cockpit controller 20 to interact with the central integrated domain controller 10 to exchange cockpit control information, including but not limited to at least one of Ethernet and a high-speed serial interface (e.g., GMSL). The basic cockpit data sharing interface is used for the extended intelligent cockpit controller 20 to interact with the central integrated domain controller 10 to exchange cockpit data, including but not limited to at least one of Ethernet and a high-speed serial interface. The basic cockpit data sharing interface serves as a channel for the extended intelligent cockpit controller 20 to interact with the central integrated domain controller 10 to exchange cockpit data, or as an external output channel. It can meet the needs of mutual transmission of extended cockpit function data. The interacted cockpit data can be real-time data and historical data, and it can also meet the needs of external cockpit data output, for example, by interfacing with third-party devices (such as mobile phones, smart home devices, cloud servers) or other modules (such as power amplifiers, scene engines).
[0041] For example, the cockpit control communication interface includes Ethernet. The intelligent cockpit controller 20 interfaces with the central integrated domain controller 10 via EthPy (Ethernet Physical Layer). The Ethernet interface can carry the transmission of large amounts of data within the cockpit (such as high-definition video streams and multi-channel sensor data), facilitating the rapid and efficient transmission of cockpit control data. Alternatively, the cockpit control communication interface includes GMSL2. The intelligent cockpit controller 20 interfaces with the central integrated domain controller 10 via the GMSL2 interface, enabling synchronous transmission of high-definition video and control signals.
[0042] The design of the 1041 reserved interface for cockpit function expansion aligns with the development trends of software-defined vehicles and domain centralization, enabling intelligent cockpit functions to be expanded on demand without requiring disruptive modifications to the hardware architecture, thus reducing development and maintenance costs. High-speed interfaces such as Ethernet and GMSL ensure real-time interaction of cockpit function-related data, enhancing the user experience. Furthermore, the cockpit data output capability through the cockpit data sharing interface facilitates the realization of scenarios such as vehicle-to-home connectivity and third-party application integration.
[0043] For example, such as Figure 4 The diagram shows the external connection of the intelligent cockpit controller. The intelligent cockpit controller 20 is used to further expand the intelligent cockpit functions based on the basic cockpit module 102, realizing the upgrade from basic cockpit functions to intelligent cockpit functions. The upgraded intelligent cockpit functions include, but are not limited to, AI models, local large models, map navigation, multimedia (music, video, karaoke), ecosystem services (vehicle-home interconnection, mini-programs), application store, driver monitoring system (DMS) / occupant monitoring system (OMS), power amplifier, super account, scene engine, intelligent network connection and other non-functional safety cockpit functions.
[0044] Music, video, and karaoke functions are implemented through audio and video decoding and audio processing technologies (such as high-fidelity audio output and multi-channel audio synchronization); the karaoke function needs to integrate audio acquisition, mixing, and effects processing modules to meet entertainment and interactive needs; AI models provide the cockpit with capabilities such as natural language understanding, voice interaction, and scene prediction (such as accurate voice command recognition and intelligent recommendations for driving scenarios); local large models (such as pre-trained models based on in-vehicle computing power) can achieve offline voice interaction and localized content recommendations, reducing dependence on the cloud and improving response speed and data security; mini-programs support quick access to third-party applications (such as coffee shop mini-programs that can "automatically unlock car doors upon arrival"), expanding the boundaries of cockpit services; vehicle-home interconnection uses IoT protocols (such as Bluetooth Mesh and Wi-Fi) to achieve linkage between vehicle and home devices (air conditioning, lighting, security) (such as automatic unlocking of doors after leaving the vehicle). (Automatic turn-off of home lights); Super Account enables multi-device account synchronization (such as binding mobile phone and vehicle accounts to synchronize music playlists and navigation history), improving user experience consistency; App Store provides application download, update, and permission management capabilities to meet users' personalized needs (such as downloading games and utility applications); DMS monitors driver fatigue and distraction through cameras and infrared sensors, triggering voice reminders and safety warnings; OMS monitors occupant status (such as children left behind, occupant location), linking with airbags, air conditioning, and other systems to ensure occupant safety; Scene Engine automatically triggers scenes based on environment, time, and user habits (such as automatically turning on navigation, air conditioning, and music in "commuter mode"); Intelligent Connectivity enables vehicle-to-vehicle and vehicle-to-infrastructure communication through 5G and V2X, supporting remote diagnostics, OTA upgrades, vehicle-to-infrastructure collaboration, and other functions, improving cockpit intelligence and safety. By expanding the functionality of the intelligent cockpit controller 20, it aligns with the trend of software-defined vehicles. Through high-performance chips, it achieves synergy between hardware foundation and software empowerment, enabling the entire vehicle's in-vehicle OS, third-party applications, and IoT devices to construct a cockpit-vehicle-home-cloud usage scenario, meeting the needs of a full-scenario intelligent experience.
[0045] In an exemplary embodiment, the function expansion reserved resource 104 also includes intelligent driving reserved resources; when the intelligent cockpit controller 20 is connected to the central integrated domain controller 10 through the cockpit function expansion reserved interface 1041, while the intelligent cockpit controller 20 expands the intelligent cockpit functions, the intelligent assisted driving module 103 upgrades the intelligent assisted driving functions based on the intelligent driving reserved resources. In addition to implementing L2 level intelligent assisted driving functions, the intelligent assisted driving module 103 is also used to implement high-speed navigation assist (NOA) functions.
[0046] In one embodiment, such as Figure 5The diagram shows a structural schematic of the extended intelligent driving function. The function extension reserved resource 104 also includes an intelligent driving extension reserved interface 1042. The integrated electronic and electrical system also includes an autonomous driving domain controller 30, which is connected to the central integrated domain controller 10 through the intelligent driving extension reserved interface 1042. The intelligent driving extension reserved interface 1042 enables data sharing between the autonomous driving domain controller 30 and the central integrated domain controller 10, allowing for flexible configuration of the intelligent driving function, expanding the bandwidth supported by the product, and maintaining cost-effectiveness.
[0047] For example, the autonomous driving domain controller 30 is used to implement road navigation assistance functions and / or Level 3 and above autonomous driving assistance functions. The autonomous driving domain controller 30 can be implemented using a high-performance computing unit, which is sufficient to support the implementation of road navigation assistance functions and Level 3 and above autonomous driving assistance functions.
[0048] The functions implemented by the autonomous driving domain controller 30 include, but are not limited to: model-based city navigation assistance, highway navigation assistance, lane centering control (LCC), and one or more of the following L3 and above autonomous driving assistance functions: L3 and above autonomous driving assistance functions include, but are not limited to: driver not in the loop (AVP), intelligent parking (APA), automatic parking (APO), and remote parking (RPA). City navigation assistance refers to functions such as lane keeping, traffic light recognition, roundabout passage, and pedestrian avoidance in complex urban roads, relying on the fusion of high-precision maps and real-time environmental perception. Highway navigation assistance refers to automatic lane changing, ramp merging / exiting, and dynamic speed adjustment in closed road scenarios, requiring compliance with ASIL-D functional safety level. Lane centering control achieves lane line tracking through cameras and millimeter-wave radar, providing basic lateral control capabilities for L2-level systems. AVP refers to hands-free driving within a specific ODD (Design Operating Domain), and the system must have fault self-diagnosis and degradation strategies; APA refers to automatically planning parking paths and controlling the steering wheel; APO refers to fully automatic parking in / out, supporting perpendicular / parallel parking spaces; RPA: remotely controlling vehicle parking via a mobile app, suitable for narrow parking scenarios.
[0049] In addition, the autonomous driving domain controller 30 can also implement one or more of the following autonomous driving assistance functions, including but not limited to: Forward Collision Warning (FCW), Automatic Emergency Braking (AEB), Lane Departure Warning (LDW), Lane Departure Mitigation (LDP), and Automatic Emergency Steering (AES). Correspondingly, the intelligent assisted driving module 103 implements one or more of the following: model-based highway navigation assistance, LCC, APA, APO, and RPA. Furthermore, the intelligent assisted driving module 103 reserves redundancy for intelligent driving computing units to enable safe parking in the event of a failure of the autonomous driving domain controller 30.
[0050] For example, such as Figure 6 The diagram shows the structure of the autonomous driving domain controller 30. This controller can be further expanded with various perception modules, including but not limited to a left front-view camera, a right front-view camera, a rear-view camera, front-view camera 1, front-view camera 2, a left rear camera, a right rear camera, a LiDAR, a front radar, a left front corner radar, a right front corner radar, a right rear corner radar, and a left rear corner radar. Furthermore, the autonomous driving domain controller 30 includes various GMSL2, GMSL3, and EthPay interface resources, facilitating the expansion of peripherals and data sharing and interaction with the central integrated domain controller 10. For example, the autonomous driving domain controller 30 and the central integrated domain controller 10 can simultaneously access two CAN network segments to achieve communication redundancy; and / or, the autonomous driving domain controller 30 and the central integrated domain controller 10 communicate via a UART port to achieve mutual monitoring, enabling seamless switching and takeover in the event of a failure in either the autonomous driving domain controller 30 or the central integrated domain controller 10.
[0051] For example, the function expansion reserved resource 104 also includes intelligent driving reserved resources, and the central integrated domain controller 10 also includes an intelligent driving redundancy module corresponding to the autonomous driving domain controller 30. This intelligent driving redundancy module can support the implementation of L3 and above high-level autonomous driving functions based on the intelligent driving reserved resources. Pre-reserving intelligent driving resources in the central integrated domain controller can avoid upgrade failures due to insufficient hardware computing power during subsequent upgrades, reduce technical upgrade costs, provide a hardware foundation for the implementation of L3 and above autonomous driving assistance functions, and provide technical assurance for the high reliability of L3 and above autonomous driving assistance functions through the design of the intelligent driving redundancy module, supporting safe operation in complex scenarios, thereby achieving a seamless upgrade from assisted driving to high-level intelligent driving.
[0052] For example, the intelligent driving extended reserved interface 1042 includes a communication interface for intelligent driving control and a perception data sharing interface for at least one perception module.
[0053] For example, the perception data sharing interface includes at least one of a high-speed serial interface and a CAN bus interface; the high-speed serial interface is used for perception data sharing of the vision perception module; the CAN bus interface is used for perception data sharing of the radar perception module. Specifically, the vision perception module includes a front fisheye surround-view camera, a rear surround-view fisheye camera, a left surround-view fisheye camera, and a right surround-view fisheye camera, as well as a front-view camera 1, a front-view camera 2, a left front camera, a right front camera, a rear-view camera, a right rear camera, a left rear camera, a driver monitoring camera, etc. The radar perception module includes millimeter-wave radar, ultrasonic radar, etc.
[0054] The communication interface of the intelligent driving control includes a universal asynchronous transmit / receive interface (API) for status monitoring of the autonomous driving domain controller 30 and the central integrated domain controller 10. The communication interface of the intelligent driving control enables status monitoring and command transmission between the autonomous driving domain controller 30 and the central integrated domain controller 10, ensuring real-time response to system-level faults.
[0055] In summary, this disclosure provides a central integrated domain controller 10 that meets the requirements of cockpit-driver integration. Using this as a base, it can achieve Level 2 intelligent driving assistance functions. When there is a need to expand to achieve Level 3 autonomous driving, a high-performance ADC is externally connected as an autonomous driving domain controller 30. Hardware serialization and deserialization are used to achieve camera data sharing, and a CAN bus enables millimeter-wave radar data sharing. Vision, millimeter-wave radar, and lidar serve as redundant peripheral sensors. A UART serial port enables mutual monitoring of the status between the central integrated domain controller 10 and the autonomous driving domain controller 30, thus achieving L3 autonomous driving compatibility in the architecture. Simultaneously, the central integrated domain controller 10 integrates intelligent driving, intelligent cockpit, and vehicle control functions, realizing a central integrated domain control that supports intelligent driving, cockpit, and vehicle control from a single base. This provides a foundation for the transition of vehicle EEA from regional integration to central integrated domain control. Furthermore, the highly integrated approach reduces the single-vehicle BOM (Bill of Materials organized for a single vehicle), directly lowering the overall vehicle cost.
[0056] In summary, this "base" achieves compatibility design for L2 intelligent assisted driving and L3 autonomous driving; peripherals such as cameras and millimeter-wave devices are shared through deserializers and serializers, supporting flexible expansion. It can also be adapted to different vehicle configurations, improving the architecture's support for product bandwidth.
[0057] The above description is merely a preferred embodiment of this disclosure and is not intended to limit this disclosure. Any modifications or equivalent substitutions made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
