By comparing the performance parameters of multiple signal transmission interfaces to match the access mode, the steps of generating the network interface matching result are as follows: S101: Based on the vehicle network environment information, analyze the vehicle network environment in real time, including the strength and transmission rate of multiple signals, including Wifi, 5G, 4G, and Bluetooth, and generate network condition analysis data; In sub-step S101, real-time analysis is performed based on the vehicle network environment information, and data of various signals are collected from the vehicle's internal network environment, including the signal strength and transmission rate of Wifi, 5G, 4G and Bluetooth.

The score takes into account two key performance indicators: transmission rate and stability. The weight adjustment reflects the different requirements for rate or stability in different scenarios. Parameter meaning and setting value: is the average transmission rate, assumed to be 100 Mbps, reflecting the average transmission rate of the network interface in recent performance tests; A score for transmission stability, assumed to be 95%, reflects the stability ratio of the network interface during continuous operation; is the weight coefficient of the transmission rate, assumed to be 0.6; is the weight coefficient of transmission stability, assumed to be 0.4; Substitute the parameters into the formula for calculation: The result 98 shows that the comprehensive performance score of the network interface after considering the speed and stability is 98. The score result is used by the vehicle system to select the network interface that best suits the current network environment and user needs, ensure the efficiency and stability of data communication, and optimize the vehicle communication experience.

[0028] S103: Based on the network performance evaluation result, according to the transmission stability and transmission rate of the multiple connection modes, matching the connection mode for access for the vehicle-mounted electronic device, and generating a network interface matching result; In sub-step S103, based on the aforementioned 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 terms of transmission stability and rate, and using a decision support system, such as a rule-based reasoning system or a multi-standard decision analysis method, such as a hierarchical analysis process, to evaluate and select the connection method that best suits the current network environment and the needs of the vehicle-mounted electronic equipment.

The process involves extracting the serial number from each network request issued by the device, and matching the target serial number with the authentication information stored in the user database. The matching process uses database query languages ​​such as SQL to ensure that the serial number of each device can find the corresponding authentication information in the database. It will check whether the device's security certificate is valid, including the issuance date and expiration date of the certificate. Digital signatures and encryption technology are used to verify the authenticity and integrity of the certificate, and form a device authentication check record.

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. The record includes the access level and specific permission settings of each device, such as which devices can access the vehicle's diagnostic information and which devices can only access the entertainment system.

If the device's request matches its permission record, access is allowed, otherwise it is denied. The access control list is updated in real time according to new access requests and permission changes to ensure that the list always reflects the latest access status. After each permission verification, an access permission matching record is generated. The record details the access request, permission verification result and access status of each device. The record provides important support for the secure access management of the vehicle system, ensuring that only authorized devices can access sensitive information or operate the vehicle system.

The process uses an operating system identification tool, such as Nmap or a similar network scanning tool. 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. Next, the operating system of each device is compared with the compatibility list. The list includes all operating system versions and configurations compatible with the vehicle system. Through the comparison process, the devices that need to adjust the communication protocol due to version or configuration incompatibility are identified. The process involves data screening and classification, and uses database query 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 adjustment is required for each device, providing accurate basic data for the next step of protocol configuration adjustment.

Technologies 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. Target operations rely on a protocol compatibility database, which records the protocol versions and port information supported by each operating system. Target adjustments are batch processed through automated scripts to ensure that devices of each operating system can communicate with the vehicle-mounted system through the optimal configuration. The generated protocol configuration adjustment records describe the specific protocol parameters required for each operating system and the adjustments made, providing a verifiable record to ensure the compatibility and security of communications.

[0034] S303: Based on the protocol configuration adjustment record, the stability of the connection of the on-board electronic equipment and the continuity of data transmission are tested in real time to generate an interface adaptation result; In sub-step S303, the protocol configuration adjustment record is used to perform real-time connection stability and data transmission continuity tests. The test uses network performance testing tools such as Wireshark and Ping to monitor and evaluate the response time, data packet loss rate and latency of the vehicle electronic device connection to ensure that the communication interface of each device can operate stably. During the target test, real-time adjustments are made to any problems that arise, such as reconfiguring network parameters or updating drivers to adapt to the needs of different operating systems. The generated interface adaptation results provide performance indicators and test pass status for each device interface. The target results are critical to ensuring stable and continuous communication of multiple devices in the vehicle system, thereby ensuring the overall network performance and user experience of the vehicle system.
