TECHNICAL FIELD

[0002] The field of automotive communication technology focuses on communication mechanisms between the interior and exterior of vehicles, including communication and data exchange between vehicles, vehicles and infrastructure, vehicles and networks, and vehicles and pedestrians. It involves vehicle-mounted networks, vehicle-mounted wireless local area networks, and Internet of Vehicles technology. By utilizing modern communication and network protocols, vehicles can receive and send critical information in real time during driving, including traffic conditions, accident warnings, and environmental monitoring data. This supports remote vehicle monitoring and control, and provides technical support for autonomous driving and intelligent transportation systems, aiming to improve road safety, enhance traffic efficiency, and optimize the driving experience.

[0003] Among them, the method for virtually accessing vehicle-mounted electronic devices to vehicle-mounted functions focuses on virtually accessing personal and vehicle-mounted electronic devices, including smartphones, tablets, and vehicle-mounted intelligent devices, to the main functional systems of the vehicle through virtualization technology. This allows device users to directly operate the vehicle's entertainment system, navigation system, and various controllable functions through their own devices, improving the convenience and personalized experience of operation, enhancing the accessibility of vehicle functions, and improving the overall intelligence of the vehicle through efficient information integration.

[0004] Traditional vehicle-mounted electronic device virtual access to vehicle-mounted function technology has deficiencies in dynamic matching of network interfaces, multi-device compatibility, real-time data processing, and security control. In a rapidly changing network environment, it cannot effectively switch to the optimal network in real time, affecting the stability of communication and the efficiency of data transmission. Compatibility issues exist between different operating systems and devices, making it difficult to provide flexible adaptation strategies. In terms of security, the traditional fixed permission management mode cannot provide sufficient security in the face of complex user scenarios and rapidly changing access requests. Data synchronization does not distinguish the importance of vehicle-mounted functions, which may delay the processing of critical information and affect the timeliness of driving decisions. However, there is a lack of sufficient intelligent support in resource allocation and fault management, which cannot guarantee the efficient operation of vehicle-mounted systems in critical situations.

[0069] In the S101 sub-step, based on the real-time analysis of the vehicle-mounted network environment information, the data of various signals is collected from the vehicle internal network environment, including the signal strength and transmission rate of Wifi, 5G, 4G and Bluetooth, the data collection process involves the use of wireless signal strength detection tools and network rate test software such as Speedtest, after collecting data, using data filtering algorithm such as low-pass filter or moving average filter, remove noise and outliers, ensure the accuracy and reliability of the data, the collected data is formatted for subsequent analysis, the target data is integrated to form network condition analysis data, which provides necessary basic information for subsequent network performance evaluation.

[0070] S102: Based on the network condition analysis data, the performance parameters of multiple network interfaces are compared, including transmission rate and transmission stability, the performance of multiple connection modes is evaluated, and network performance evaluation results are generated;

[0071] The specific formula for evaluating the performance of multiple connection methods is:

[0077] The formula is used to calculate the comprehensive performance score of different network interfaces, and the optimal network interface is selected. The score takes into account the transmission rate and stability, two key performance indicators, and reflects different demands for speed or stability in different scenarios through weight adjustment;

The score result is used for the vehicle-mounted system to select the most suitable network interface for the current network environment and user demand, ensuring the efficiency and stability of data communication, and optimizing the vehicle-mounted communication experience.

[0086] S103: Based on the network performance evaluation results, according to the transmission stability and transmission rate of multiple connection modes, the connection mode of the vehicle-mounted electronic device is matched, and the network interface matching result is generated;

[0087] In the S103 sub-step, based on the network performance evaluation results, the optimal network interface of the vehicle-mounted electronic device is matched, the process includes analyzing the performance of each network interface in transmission stability and rate, using decision support system such as rule-based reasoning system or multi-criteria decision analysis method such as analytic hierarchy process, evaluating and selecting the most suitable connection mode for current network environment and vehicle-mounted electronic device demand, for the device requiring high real-time, will preferentially match the high transmission rate of 5G network, for the device with higher stability requirement, select the stronger stability of 4G or WiFi, the selection of each option is based on performance data and device demand, the generated network interface matching result lists the recommended best network interface for each vehicle-mounted electronic device, which provides guarantee for stable operation and efficient communication of vehicle-mounted device.

[0088] Please refer to Figure 3 , receive the network interface matching result, authenticate the multiple devices requesting access, match and record the access authority according to the device type and user identity, and the step of generating the access authority matching record is as follows:

[0089] S201: Receive the network interface matching result, and match by using the device identification code and the user database, check the serial number and authentication information of the multiple devices requesting access, and generate the device authentication check record;

[0090] In the S201 sub-step, through the data received by the network interface matching result, the device identification technology is adopted, and each device requesting access is identified by using the device serial number, the process involves extracting the serial number from each network request sent by the device, matching the target serial number with the authentication information stored in the user database, the matching process uses database query language such as SQL, ensures that the serial number of each device can find the corresponding authentication information in the database, checks whether the security certificate of the device is valid, including the issue date and expiration date of the certificate, uses digital signature and encryption technology to verify the authenticity and integrity of the certificate, forms the device authentication check record, and the target record lists the identification and authentication status of each device in detail, which provides necessary information and security guarantee for subsequent permission setting.

[0091] S202: Based on the device authentication check record, compare the device type and user identity database to identify the access level and permission setting of multiple devices, and generate the permission verification record;

[0092] In the S202 sub-step, based on the device authentication check record, the type and user identity information of each device are analyzed, an access control algorithm such as a role-based access control model is used to define and identify the access level and permission settings of the device, including comparing the device type and user identity with the preset access permission template in the database, the access permission template in the database divides different access levels according to the device type and user level, through target comparison and matching, a permission verification record is generated, which includes the access level and specific permission settings of each device, such as which devices can access the diagnostic information of the vehicle and which devices can only access the entertainment system. Such permission verification records ensure the data security of the vehicle-mounted system and the protection of user privacy.

[0093] S203: Use the permission verification record to match and record the access permissions of multiple devices, update the access control list in real time, and generate an access permission matching record;

[0094] In the S203 sub-step, the generated permission verification record is used to match and record the device access permissions, the process includes updating and managing the access control list using the permission management system, the system monitors and records the access request and corresponding permission verification result of each device in real time, if the request of the device matches its permission record, access is allowed, otherwise it is rejected. The access control list is updated in real time according to new access requests and permission changes, ensuring that the list always reflects the latest access status. After each permission verification, an access permission matching record is generated, which details the access request, permission verification result and access status of each device. The record provides important support for the safe access management of the vehicle-mounted system, ensuring that only authorized devices can access sensitive information or operate the vehicle system.

[0095] Please refer to Figure 4 , according to the access permission matching record, detect and analyze the operating system types of multiple access electronic devices, and adjust the communication protocol and interface settings according to the operating system type to optimize the stability and continuity of the device and vehicle-mounted system connection. The steps of generating the interface adaptation result are as follows:

[0096] S301: Based on the access permission matching record, detect the operating systems of multiple devices, identify the operating systems used by the devices, and check the operating system compatibility list to identify access devices that need to adjust the communication protocol, and generate an operating system identification record;

[0097] In the S301 sub-step, based on the obtained access permission matching record, detection and identification of the operating system are performed, and the process uses operating system identification tools such as Nmap or similar network scanning tools. The target tool can determine the operating system version and type running on each device by analyzing the data packets from the device to the server. Then, the operating system of each device is compared with the compatibility list, which includes all operating system versions and configurations compatible with the vehicle system. Through the comparison process, devices that need to adjust the communication protocol due to version or configuration incompatibility are identified. The process involves data filtering and classification, using database queries and logical judgment algorithms to process target information to ensure that the operating system of each device meets the compatibility requirements. The generated operating system identification record lists the operating system type, compatibility status, and whether the protocol needs to be adjusted for each device, providing accurate basic data for the next step of protocol configuration adjustment.

[0098] S302: Based on the operating system identification record, match communication protocol parameters for multiple operating systems, including port configuration and protocol version, adjust interface configuration to match the characteristics of multiple operating systems, and generate protocol configuration adjustment records.

[0099] In the S302 sub-step, according to the operating system identification record, appropriate communication protocol parameters are matched for multiple operating systems, including adjusting port configuration and protocol version for different operating systems to ensure efficient communication with the vehicle system. The techniques used include network configuration management tools and custom scripts to automatically adjust interface settings, such as changing TCP / IP settings and updating SSL / TLS certificates. The target operation relies on a protocol compatibility database that records the protocol versions and port information supported by each operating system. Through automated scripts, target adjustments are processed in batches to ensure that devices of each operating system can communicate with the vehicle system through optimal configurations. The generated protocol configuration adjustment record describes the specific protocol parameters required for each operating system and the adjustments made, providing verifiable records to ensure communication compatibility and security.

[0100] S303: Based on the protocol configuration adjustment record, real-time test the stability of the connection of the vehicle electronic device and the continuity of data transmission, and generate interface adaptation results.

[0101] In S303, the protocol configuration adjustment record is used to perform real-time connection stability and data transmission continuity testing. Network performance testing tools such as Wireshark and Ping are used to monitor and evaluate the response time, data packet loss rate and delay of the vehicle-mounted electronic device connection, ensuring that each device's communication interface can operate stably. During the target testing process, real-time adjustments are made to problems such as reconfiguring network parameters or updating drivers to adapt to different operating system requirements. The generated interface adaptation results provide performance indicators and test pass status for each device interface. The target results are crucial for ensuring the stability and continuous communication of multiple devices in the vehicle-mounted system, and guarantee the overall network performance and user experience of the vehicle-mounted system.

[0102] Referring to Figure 5 , using the interface adaptation results, real-time synchronization of data between vehicle-mounted electronic devices and functional devices is performed, and the data update parameter configuration is adjusted according to the importance of vehicle-mounted functions. The steps for generating data synchronization parameter configuration are as follows:

[0103] S401: Based on the interface adaptation results, real-time synchronization of data between vehicle-mounted electronic devices and multiple functional devices is performed, and real-time performance of data transmission is analyzed and recorded to generate real-time data flow monitoring records;

[0104] In S401, based on the interface adaptation results, real-time synchronization of data between vehicle-mounted electronic devices and multiple functional devices is performed. Network monitoring tools such as SolarWinds or PRTG Network Monitor are used to capture and analyze data flow between the vehicle-mounted system and functional devices in real time, and real-time monitoring of data transmission speed, delay and packet loss rate is performed. Real-time performance analysis of data transmission includes calculating the data throughput of each device, i.e. the amount of data processed per second. Combined with stability analysis of data flow, the generated real-time data flow monitoring records provide detailed data transmission performance indicators, including throughput, delay and stability score, providing accurate benchmark data for subsequent data transmission configuration optimization.

[0105] S402: Based on the real-time data flow monitoring records, analyze the functions of multiple vehicle-mounted devices, and evaluate the data transmission configuration required by multiple functions by analyzing the data transmission requirements of multiple vehicle-mounted functions, and generate transmission requirement analysis results;

[0106] In S402, based on real-time data stream monitoring records, analyze the data transmission requirements of various functions in the vehicle-mounted electronic device, and use data analysis software such as Tableau or Microsoft Power BI to visualize the captured data and identify which vehicle functions such as navigation systems, entertainment systems or safety monitoring systems have higher requirements for data transmission speed and stability. Evaluate the data transmission requirements of each function, calculate the relationship between function usage frequency and data volume, and evaluate the results to determine the optimal data transmission configuration required by each function, including the minimum required bandwidth and priority settings. The generated transmission requirement analysis results provide a detailed description of the data transmission configuration adjusted according to the importance and data intensity of each function, providing a scientific basis for synchronization settings.

[0107] S403: Based on the transmission requirement analysis results, calculate the importance of multiple functions and adjust the data synchronization settings, including data packet size and data update frequency, to generate data synchronization parameter configuration;
