[0024] In recent years, with the rapid development of smart cockpit technology, related solutions have gradually matured. Smart cockpits not only integrate traditional entertainment, navigation and other functions, but also introduce new functions such as in-car monitoring and driver status detection. At the same time, ADAS functions are gradually adopted by the whole vehicle as independent controllers to realize key functions such as automatic parking and lane keeping. However, simplifying the whole vehicle architecture and reducing costs have become industry trends, prompting the cabin-parking integrated controller to become the mainstream technical solution.

[0025] The cabin-parking integrated controller integrates cockpit and parking control, which not only reduces the number of controllers and simplifies the architecture, but also enables the sharing of hardware resources, reduces system costs, and improves computing and communication efficiency. The MCU+SOC architecture is usually used in related technologies. The MCU is connected to the CAN network of the vehicle through the Controller Area Network (CAN) communication interface, and exchanges real-time information with other control units of the vehicle to ensure reliable communication between the cockpit and parking functions. The SOC focuses on processing complex data tasks, such as high-resolution image processing, in-vehicle multimedia systems, parking path planning and other computing-intensive tasks.

[0026] In order to ensure high throughput of cockpit data and high real-time requirements of parking data, data communication between MCU and SOC is usually carried out through SPI or UART interface. Figure 1 As shown in the figure, the MCU communicates with the vehicle through the CAN bus to obtain data, and interacts with the SOC through the SPI interface or UART interface. These interfaces can provide a stable and efficient communication link to ensure the timeliness and accuracy of data transmission.

[0027] However, the related art has the following problems:

[0028] 1. The cockpit data and parking data are transmitted through the same communication link, which makes it impossible to meet the high throughput and high real-time requirements during the communication process, resulting in low communication efficiency between MCU and SOC;

[0029] 2. The communication interface between MCU and SOC is single. Once the hardware link fails, the cockpit and parking functions will all fail, and the communication robustness is insufficient.

[0030] To solve the above problems, various embodiments of the present invention provide a communication method for a cabin-mooring integrated controller, the method comprising: configuring a first communication link and a second communication link between an MCU and a SOC in the cabin-mooring integrated controller;

[0031] Sending first control information to the MCU, the first control information is used to instruct the MCU to send the vehicle's cockpit data to the SOC through the first communication link, and to send the vehicle's parking data to the SOC through the second communication link; receiving the first information sent by the MCU, and sending the first information to the vehicle; the first information includes: a driver associated with the cockpit data, and a parking calculation result associated with the parking data;

[0032] Sending second control information to the SOC, the second control information is used to instruct the SOC to receive the cockpit data through the first communication link and to receive the parking data through the second communication link, so that the SOC uses a preset component to determine the first information based on the cockpit data and the parking data, and sends the first information to the MCU through the first communication link and the second communication link.

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0034] According to an embodiment of the present invention, a communication method of a cabin-mooring integrated controller is provided. Figure 2 FIG. 1 is a flow chart of a communication method of a cabin-mooring integrated controller provided by an embodiment of the present invention. Figure 2 As shown, the method comprises the following specific steps:

[0035] Step S201, configuring a first communication link and a second communication link between the MCU and the SOC in the cabin-motorcycle integrated controller;

[0036] Step S202, sending first control information to the MCU, the first control information is used to instruct the MCU to send the vehicle's cockpit data to the SOC through the first communication link, and to send the vehicle's parking data to the SOC through the second communication link; receiving the first information sent by the MCU, and sending the first information to the vehicle; the first information includes: a driver associated with the cockpit data, and a parking calculation result associated with the parking data;

[0037] Step S203, sending second control information to the SOC, the second control information is used to instruct the SOC to receive the cockpit data through the first communication link, and to receive the parking data through the second communication link, so that the SOC uses a preset component to determine the first information based on the cockpit data and the parking data, and sends the first information to the MCU through the first communication link and the second communication link.

[0038] In one possible implementation, the cabin-parking integrated controller may refer to a unified control system that integrates intelligent cockpit control and automatic parking control functions; the architecture of the cabin-parking integrated controller may be composed of MCU and SOC, wherein the MCU is responsible for communicating with the CAN bus of the entire vehicle and accessing various sensors and control units of the vehicle, and the SOC is responsible for high-performance data processing of the vehicle, such as multimedia display and vehicle networking.

[0039] Furthermore, the first communication link may be used to transmit the vehicle's cabin data between the MCU and the SOC, and the second communication link may be used to transmit the vehicle's parking data between the MCU and the SOC.

[0040] Here, the cockpit data may include but is not limited to: video data, audio data, navigation data, in-vehicle environment control data, user interface data, etc.; since the above-mentioned cockpit data requires a high-bandwidth communication link to be transmitted quickly to avoid lags and delays, the transmission of the cockpit data requires a high-throughput transmission method.

[0041] Furthermore, parking data may include but is not limited to: vehicle sensor data, camera images, control instructions, etc.; since the above parking data is summarized during the vehicle's automatic parking process, the sensors continuously detect the vehicle's surrounding environment, and the system needs to quickly make steering, braking and other control instructions based on real-time data, so the transmission of parking data requires a high real-time transmission method.

[0042] In a possible implementation, sending the first control information to the MCU may be implemented based on the following steps:

[0043] Generate first control information, the first control information includes instruction information to the MCU, the instruction information is used to instruct the MCU to send the vehicle cabin data to the SOC through the first communication link, and send the vehicle parking data to the SOC through the second communication link;

[0044] The first control information is sent to the MCU, so that the MCU performs a corresponding operation based on an instruction of the first control information.

[0045] Furthermore, sending the second control information to the SOC may be implemented based on the following steps:

[0046] Generate second control information, the second control information includes instruction information to the SOC, the instruction information is used to command the SOC to receive the vehicle cabin data sent by the MCU through the first communication link, and to receive the vehicle parking data sent by the MCU through the second communication link;

[0047] The second control information is sent to the SOC, so that the SOC performs a corresponding operation based on an instruction of the second control information.

[0048] Furthermore, the SOC uses a preset component to determine the first information based on the cockpit data and the parking data, which can be implemented based on the following steps:

[0049] Firmware in the SOC and / or an operating system are used to determine a driver associated with the cockpit data based on a cockpit-related algorithm, and to determine a parking calculation result associated with the parking data based on a parking-related algorithm.

[0050] Among them, the firmware in the SOC can refer to low-level software embedded inside the chip or closely coordinated with the chip, which can be responsible for controlling and managing the hardware functions of the SOC and providing basic software support, rather than directly designing complex data computing tasks; the operating system in the SOC can be responsible for managing resources, running applications and services, and performing complex data processing and algorithm calculations.

[0051] In a possible implementation, determining a driver associated with cockpit data based on a cockpit-related algorithm may be implemented based on the following steps:

[0052] Decode and parse cockpit data, converting cockpit data from a data link protocol format into a format recognizable by cockpit-related algorithms;

[0053] Use cockpit-related algorithms to perform preset analysis on the parsed cockpit data. The preset analysis may include but is not limited to: image analysis processing, audio analysis processing;

[0054] Determine the driver function corresponding to the cockpit data based on the results of the preset analysis, and design the driver's interface and functions to enable the driver to interact with the hardware of the cockpit system.

[0055] For example, the operating system in the SOC obtains the video stream corresponding to the camera, performs preprocessing and real-time image processing on the video stream, and generates a corresponding video decoding driver to display the processed image on the cockpit display.

[0056] In a possible implementation, determining the parking calculation result associated with the parking data based on a parking-related algorithm may be implemented based on the following steps:

[0057] Decode and parse parking data, converting the parking data from a data link protocol format into a format recognizable by parking-related algorithms;

[0058] Fusing parking data from different sensors to obtain a comprehensive view of the environment;

[0059] Parking-related algorithms are used to determine semantic information such as parking spaces, lane lines, obstacles, etc., and the parking calculation results of the vehicle are determined based on the semantic information.

[0060] Here, the parking calculation result may include: parking path, vehicle posture information, and parking assistance instruction information.

[0061] Through the above method, the cockpit data and parking data are transmitted through different communication links, which reduces the interference and conflict between the data streams and improves the overall performance and efficiency of the data transmission of the cabin-parking integrated controller; using two independent communication links to process different types of data reduces the risk of failure of a single link, thereby improving the stability and reliability of the system.

[0062] In a specific embodiment, the method further comprises:

[0063] The initial cockpit data of the vehicle is sent to the MCU via the first CAN bus, and the initial parking data of the vehicle is sent to the MCU via the second CAN bus, so that the MCU determines the cockpit data of the vehicle based on the initial cockpit data, and determines the parking data of the vehicle based on the initial parking data.

[0064] In a possible implementation, sending initial cockpit data of the vehicle to the MCU via the first CAN bus includes:

[0065] Initial cockpit data is obtained from the cockpit control module of the vehicle, the initial cockpit data is converted into a data frame conforming to the CAN protocol, and sent to the MCU via the first CAN bus.

[0066] Here, the initial cockpit data refers to basic data related to the vehicle cockpit collected from cockpit-related equipment or sensors; for example, the initial cockpit data may include: air conditioning status, entertainment system parameters, instrument panel information, etc.

[0067] In a possible implementation, sending the initial parking data of the vehicle to the MCU via the second CAN bus includes:

[0068] Initial parking data is obtained from the parking assistance system of the vehicle, the initial parking data is converted into a data frame conforming to the CAN protocol, and is sent to the MCU through the second CAN bus.

[0069] Here, the initial parking data is basic data obtained from parking sensors or other parking-related devices; for example, the initial parking data may include: radar data, camera data, and ultrasonic ranging information.

[0070] Through the above method, the initial cockpit data is transmitted through the first CAN bus and the initial parking data is transmitted through the second CAN bus, which can improve the transmission efficiency of each data and avoid system delays or errors caused by functional conflicts; it can prevent mutual interference between cockpit and parking data and ensure real-time and reliability.

[0071] In a specific embodiment, sending first control information to the MCU, the first control information being used to instruct the MCU to send the vehicle's cabin data to the SOC through the first communication link, and sending the vehicle's parking data to the SOC through the second communication link, is implemented based on the following steps:

[0072] Determine the data in the cockpit data and the parking data whose data volume is greater than or equal to the throughput threshold as the first throughput data, determine the data whose data volume is less than the throughput threshold as the second throughput data, determine the data in the cockpit data and the parking data whose transmission delay is greater than or equal to the time threshold as the first real-time data, and determine the data whose transmission delay is less than the time threshold as the second real-time data;

[0073] The cockpit data satisfying both the first throughput data and the first real-time data is used as the first cockpit data, and the cockpit data satisfying both the second throughput data and the second real-time data is used as the second cockpit data;

[0074] The parking data satisfying both the first throughput data and the first real-time data is used as the first parking data, and the parking data satisfying both the second throughput data and the second real-time data is used as the second parking data;

[0075] Send first control information to the MCU, where the first control information is used to instruct the MCU to send first cockpit data to the SOC through the SPI channel in the first communication link, to send second cockpit data to the SOC through the UART channel in the first communication link, and to send first parking data to the SOC through the SPI channel in the second communication link, and to send second parking data to the SOC through the UART channel in the second communication link.

[0076] In a possible implementation, when the cockpit data satisfies both the first throughput data and the first real-time data, the first cockpit data characterized by a large transmission data volume and low real-time requirement is transmitted using the SPI channel in the first communication link;

[0077] When the cockpit data satisfies both the second throughput data and the second real-time data, the second cockpit data characterized as having a small transmission data volume but a high real-time requirement is transmitted using the UART channel in the first communication link;

[0078] When the parking data satisfies both the first throughput data and the first real-time data, the first parking data is characterized as having a large transmission data volume and low real-time requirement, and is transmitted using the SPI channel in the second communication link;

[0079] When the parking data satisfies both the second throughput data and the second real-time data, the second parking data is characterized as having a small transmission data volume but a high real-time requirement, and is transmitted using the UART channel in the second communication link.

[0080] Among them, the SPI used in the SPI channel can be a synchronous serial communication protocol. By adopting full-duplex communication, the MCU and SOC can send and receive data at the same time, which makes its transmission speed much faster than the UART channel; the clock rate of the SPI can be configured as needed to adapt to different data rate requirements. When transmitting the first cockpit data and the first parking data with a large amount of data, the SPI can be transmitted at a high rate. Therefore, SPI communication is used to transmit high-throughput data.

[0081] Here, the UART channel uses an asynchronous serial communication protocol. The asynchronous mode enables the MCU and SOC to communicate without sharing a clock, so they can work in a more flexible timing environment. Therefore, UART communication is used to transmit high real-time data.

[0082] Exemplarily, the throughput threshold may be 1 megabit per second (M / s), and the time threshold may be 20 milliseconds; the throughput threshold and the time threshold may be specifically set according to requirements, and are not limited here.

[0083] In a specific embodiment, the SOC uses a preset component to determine the first information based on the cabin data and the parking data, and is implemented based on the following steps:

[0084] Based on the cockpit service component in the SOC, the first cockpit data and the second cockpit data are obtained, and the corresponding interface of the Bingling component in the SOC is called to broadcast the first cockpit data and the second cockpit data in each system of the SOC, so that each system determines the driving program in the first information based on the first cockpit data and the second cockpit data;

[0085] Based on the automatic parking service component in the SOC, the first parking data and the second parking data are obtained, and the corresponding interface of the cyber component in the SOC is called to send the first parking data and the second parking data to the QNX system in the SOC, so that the QNX system adopts the parking algorithm to determine the parking calculation result in the first information.

[0086] In a possible implementation, there may be multiple operating systems in the SOC; for example, the SOC may be installed with an Android system and a QNX system.

[0087] Among them, the Android system can be used to process multimedia entertainment information and user interaction information. For example, the data types processed by the Android system in the SOC may include multimedia content and graphical interfaces in the cockpit data; the QNX system can be used to process low-level hardware control and real-time feedback data, for example, instrument panel information and sensor data in the cockpit data.

[0088] In one possible implementation, the cockpit service component in the SOC may refer to a cockpitservice component integrated in the SOC, which may be a service module for managing and providing smart cockpit functions.

[0089] Exemplarily, the services provided by the cockpit service component may include but are not limited to: information interaction and display, multimedia control, navigation, air conditioning management, voice assistant, etc.

[0090] In a possible implementation, iceoryx may be an inter-process communication middleware applicable to various operating systems, and may provide a data-independent transmission mechanism based on shared memory, so that data may be transmitted across various systems in the SOC.

[0091] Specifically, calling the corresponding interface of iceoryx can broadcast the first parking data and the second parking data between the Android system and the QNX system, so that the data between the Android system and the QNX system can be updated in real time and kept consistent, thereby promoting the collaborative work of the Android and QNX systems.

[0092] In a possible implementation, the automatic parking service component in the SOC may refer to an APA service component, which may be a service module for managing and executing the automatic parking function of the vehicle.

[0093] Exemplarily, the services provided by the APA service component may include, but are not limited to: environmental perception processing, vehicle automatic control and path planning.

[0094] In one possible implementation, the cyber component may refer to a real-time communication framework for autonomous driving, which provides a variety of communication mechanisms and user-level coroutines and performs scheduling based on task priority when resources are limited.

[0095] Specifically, by calling the corresponding interface of the cyber component to transmit the first parking data and the second parking data to the QNX system in the SOC, the transmission delay of the parking data in the SOC can be reduced, ensuring that the parking data with higher real-time performance can be quickly determined as the parking calculation result in the QNX system.

[0096] Furthermore, after the first parking data and the second parking data are transmitted to the QNX system, the corresponding interface of the cyber component can continue to be called to broadcast the first parking data and the second parking data in the QNX system, so that through the message publishing and subscription mechanism of the cyber component, multiple modules inside the QNX system can process the parking data in parallel, thereby further improving the processing efficiency of determining the parking calculation results.

[0097] Through the above method, when processing cockpit data, iceoryx is called to broadcast the first parking data and the second parking data between the Android system and the QNX system, so that the data between the Android system and the QNX system can be updated in real time and kept consistent, thereby improving the efficiency of data transmission in the cabin-parking integrated controller; calling the corresponding interface of the cyber component to transmit the first parking data and the second parking data to the QNX system in the SOC can reduce the delay of parking data transmission and further improve the real-time performance of data transmission.

[0098] In a specific embodiment, calling the corresponding interface of the Bingling component in the SOC to broadcast the first cockpit data and the second cockpit data in each system of the SOC includes:

[0099] Based on the cockpit service component in the SOC, the data parts in the first cockpit data and the second cockpit data that interact with the vehicle's CAN bus are determined, and the data parts are broadcast in various systems of the SOC by calling the corresponding interface of the Bingling component, so that the QNX system in the SOC obtains the data parts.

[0100] In one possible implementation, the CAN bus is used for real-time data exchange within the vehicle, and the data portion that interacts with the vehicle's CAN bus may refer to data that requires real-time decision-making and control; and since the QNX system is a high real-time operating system, the efficiency of data processing and return can be improved by broadcasting the data portion that interacts with the vehicle's CAN bus to the QNX system for processing.

[0101] Here, QNX obtains the data portion of the vehicle's CAN bus where there is interaction, and determines the driver in the first information corresponding to the data portion.

[0102] In a possible implementation, the cockpit service can also interact with multiple other systems or modules in the SOC and receive messages published by these systems through the Ice Antelope component.

[0103] Here, the message receiving can determine the type of message received by setting corresponding subscription rules and filtering conditions.

[0104] Through the above method, by calling the broadcast interface of the Bingling component, the QNX system can obtain and process cockpit data with high real-time requirements in real time, thereby realizing data sharing and coordination between systems, and improving the real-time performance and integrity of the system; through the low-latency, high-performance message middleware provided by the Bingling component, the cockpit service can receive and process messages from multiple systems in a timely manner, enhancing the functional integration and user experience of the cockpit system.

[0105] In a specific embodiment, based on the automatic parking service component in the SOC, obtaining the first parking data and the second parking data includes:

[0106] Sending third control information to the SOC, the third control information is used to instruct the SPI driver in the SOC to map the SPI channel in the second communication link into a first sub-channel and a second sub-channel; the first sub-channel is used to transmit the CAN message information in the first parking data, and the second sub-channel is used to transmit the sensor information in the first parking data;

[0107] Based on the automatic parking service component in the SOC, CAN message information is obtained through the first sub-channel, and sensor information is obtained through the second sub-channel.

[0108] Specifically, the SPI driver in the SOC maps the SPI channel in the second communication link into the first sub-channel and the second sub-channel; reads the first parking data in the SPI channel, parses and extracts CAN message information in the first parking data, and parses and extracts sensor information in the first parking data.

[0109] Here, the sensor information may include but is not limited to: raw data from ultrasonic radar and vehicle surrounding data from a surround-view camera.

[0110] Through the above method, by mapping the SPI channel into two sub-channels, the CAN message information and sensor information are transmitted separately. This data separation reduces information mixing and improves the efficiency of data transmission; by transmitting CAN message information and sensor data through dedicated sub-channels, real-time acquisition and processing of parking-related data can be achieved, which can ensure the rapid decision-making of the automatic parking system.

[0111] In a specific embodiment, sending the first information to the MCU through the first communication link and the second communication link includes:

[0112] Convert the format of the first information so that the first information complies with the protocol format corresponding to the SPI channel and the UART channel in the first communication link and the second communication link;

[0113] The first information conforming to the protocol format is sent to the MCU through the SOC.

[0114] Specifically, determine the data protocol format applicable to SPI and UART channels;

[0115] Performing format conversion on the first information, converting the cockpit data in the first information into the format required by the SPI channel, and formatting the parking data in the first information into the format of the UART channel;

[0116] The first information after format conversion is generated into an SPI packet and a UART data packet, and sent to the MCU.

[0117] Here, the first information is formatted so that data conforming to the protocol format can be transmitted more efficiently, thereby reducing the processing time of data on the link and improving the overall communication efficiency.

[0121] The cockpit service component 321 implements data broadcasting and subscription by calling the interface of the Bingling component 323 , and the automatic parking service component 322 transmits parking data to the QNX system by calling the interface of the cyber component 324 .
