Description

Technical Field

[0001] This disclosure relates to the field of intelligent transportation technology, and in particular to a cross-platform vehicle-road information interaction system and a cross-platform vehicle-road information interaction method. Background Technology

[0002] In recent years, highways have increasingly emphasized information reach to users to improve traffic safety, but the effectiveness needs improvement. On the one hand, major disasters often result in increased secondary accident risks because information cannot reach vehicles and users. On the other hand, while highway operation monitoring platforms and data centers have been built and continuously optimized, possessing various valuable data such as accident events, road condition information, disaster information, and service facilities, an effective path for large-scale access to vehicles and users has yet to be achieved. Improving the public's travel experience on highways and empowering the integrated development of vehicle-road-cloud collaborative industries have become a consensus and demand within the industry.

[0003] Currently, the adoption rate of 5G in intelligent connected vehicles and the penetration rate of autonomous driving are continuously increasing. Users are also using autonomous driving more frequently on highways, leading to a growing demand for highway event information. From a driving safety perspective, vehicles need to obtain timely information on beyond-line-of-sight events such as road construction and the opening / closing status of toll booths to enable safer decision-making and driving.

[0004] Highway information delivery to vehicles can rely on highway platforms and cloud control platforms to achieve a connected information service route from highway cloud to vehicle manufacturer cloud platform to in-vehicle terminal. Currently, the industry mainly relies on one-to-one interface debugging between a highway company and a vehicle manufacturer. Each new vehicle manufacturer requires a separate interface debugging process, resulting in a huge workload and collaboration costs, making it difficult to achieve continuous information services across domains and users. Some methods explore building a central platform to aggregate data from highways across provinces before forwarding it to different data users. However, this method has high requirements for the central platform's resources and data security, making it difficult to promote on a large scale. Summary of the Invention

[0008] This disclosure presents a cross-platform vehicle-road information interaction system and a cross-platform vehicle-road information interaction method. The system includes: at least one highway cloud platform, a service management platform, and a data user platform; each highway cloud platform corresponds to a different geographical region; each highway cloud platform is used to process initial road condition data of the corresponding region's highways to obtain target road condition data; the service management platform is used to receive access request information sent by the data user platform, the access request information including a target identifier corresponding to the target highway cloud platform to be accessed; and to perform access compliance determination on the target highway cloud platform and the data user platform based on the access request information.

[0014] Example 1 Figure 1 This is a structural block diagram of a cross-platform vehicle-road information interaction system 10 provided in Embodiment 1 of this disclosure. This embodiment is applicable to situations where vehicle-road information interacts across platforms. Figure 1 As shown, the cross-platform vehicle-road information interaction system 10 includes: at least one highway cloud platform 110, a service management platform 120, and a data user platform 130; each highway cloud platform 110 corresponds to a different geographical region; wherein, Each highway cloud platform 110 is used to process the initial road condition data of the corresponding area of ​​the highway to obtain the target road condition data. The service management platform 120 receives access application information sent by the data user platform 130. The access application information includes the target identifier corresponding to the target highway cloud platform 100 to be accessed. Based on the access application information, the platform performs access compliance determination on the target highway cloud platform 100 and the data user platform 130. For the target highway cloud platform 100 and the data user platform 130 that pass the determination, the platform performs identity authentication to establish an authentication link. A data transmission link is then constructed based on this authentication link. The authentication link is a secure association configuration relationship configured by the service management platform 120 to achieve identity authentication and access control between the target highway cloud platform 100 and the data user platform 130. The data transmission link is used for data transmission between the target highway cloud platform 100 and the data user platform 130. The data user platform 130 is used to obtain target road condition data from the target highway cloud platform 100 through the data transmission link, generate road condition service information by combining the vehicle's current driving information, and forward the road condition service information to the data user terminal.

[0015] This embodiment provides a cross-platform vehicle-road information interaction system 10, including: each highway cloud platform 110 for processing initial road condition data of the corresponding area of ​​the highway to obtain target road condition data; a service management platform 120 for receiving access application information sent by a data user platform 130, the access application information including the target identifier corresponding to the target highway cloud platform 100 to be accessed; and for performing access compliance determination on the target highway cloud platform 100 and the data user platform 130 according to the access application information, and for verifying the identity of the target highway cloud platform 100 and the data user platform 130 that pass the determination. The authentication link is established to create an authentication link, and a data transmission link is constructed based on the authentication link. The authentication link is a secure association configuration relationship configured by the service management platform 120 to realize identity authentication and access control between the target highway cloud platform 100 and the data user platform 130. The data transmission link is used to transmit data between the target highway cloud platform 100 and the data user platform 130. The data user platform 130 is used to obtain target road condition data from the target highway cloud platform 100 through the data transmission link, generate road condition service information by combining it with the current driving information of the vehicle, and forward the road condition service information to the data user terminal.

[0016] Among them, each highway cloud platform 110 is used to process the initial road condition data of the corresponding area of ​​the highway to obtain the target road condition data.

[0017] In this embodiment, the highway cloud platform 110 can be a server deployed in the cloud, used for data storage, calculation, and management of highways in the corresponding region. Each highway cloud platform 110 corresponds to a different geographical region. Each highway cloud platform 110 can acquire initial road condition data of the highways in the corresponding region. The initial road condition data can be raw data reflecting the real-time operating status of the highway, and can be data collected by various devices such as roadside sensing devices (e.g., video surveillance equipment, radar detection equipment), meteorological detection equipment, and event reporting systems.

[0018] As described above, after each highway cloud platform 110 acquires the initial traffic condition data of the highway, due to the heterogeneous acquisition equipment and diverse transmission channels, the initial traffic condition data often suffers from problems such as inconsistent data formats, inconsistent timestamps, spatial coordinate deviations, missing or redundant information, and noise interference. Therefore, data processing can be performed on the initial traffic condition data to obtain target traffic condition data. This data processing includes, but is not limited to, data cleaning, data format standardization, and data quality verification. The target traffic condition data can be structured traffic condition information that has undergone standardized processing, meets quality standards, and can be directly used for external sharing and services. For example, the target traffic condition data may include traffic flow, congestion level, traffic accident information, road construction information, and meteorological information for each road segment.

[0019] The service management platform 120 receives access application information sent by the data user platform 130, including the target identifier corresponding to the target highway cloud platform 100 to be accessed. Based on the access application information, the platform performs access compliance determination on both the target highway cloud platform 100 and the data user platform 130. For the target highway cloud platform 100 and the data user platform 130 that pass the determination, identity authentication is performed to establish an authentication link. A data transmission link is then constructed based on this authentication link. The authentication link is a secure association configuration relationship configured by the service management platform 120 to achieve identity authentication and access control between the target highway cloud platform 100 and the data user platform 130. The data transmission link is used for data transmission between the target highway cloud platform 100 and the data user platform 130.

[0020] In this embodiment, the service management platform 120 can be an intermediate management layer platform deployed between each highway cloud platform 110 and the data user platform 130. The data user platform 130 can send access application information to the service management platform 120, which may include the target identifier corresponding to the target highway cloud platform 100 to be accessed. After receiving the access application information sent by the data user platform 130, the service management platform 120 can perform access compliance determination on the target highway cloud platform 100 and the data user platform 130 corresponding to the target identifier. Access compliance determination refers to the process by which the service management platform 120 systematically reviews the access qualifications of the highway cloud platform 110 and the data user platform 130 according to preset access rules and review standards. The review content usually includes, but is not limited to: the applicant's legal business qualifications (such as business license information), technical security assurance capabilities (such as network security level protection certificate, data security management system), data usage compliance commitment (such as data purpose statement, user privacy protection plan), and the data sharing agreement signed by both parties. Only applicants who pass the access compliance determination can proceed to the subsequent identity authentication stage.

[0021] As described above, after the access compliance judgment is passed, the identity authentication of the target highway cloud platform 100 and the data user platform 130 can be performed to ensure the authenticity of the identities of the target highway cloud platform 100 and the data user platform 130 in communication.

[0022] It is known that an authentication link can be established based on the identity authentication result. The authentication link refers to the secure association configuration set by the service management platform 120 to achieve identity authentication and access control between the highway cloud platform 110 and the data user platform 130. For example, the authentication link may include authentication keys, access permission configurations (e.g., allowed data types, data ranges, call frequency limits), security policy bindings (e.g., encryption algorithm requirements, session timeout settings), and access log records. The authentication link can be understood as a digital expression of the secure trust relationship between the authenticated target highway cloud platform 100 and the authenticated data user platform 130. It ensures that only the authenticated data user platform 130 can access the resources of the authenticated highway cloud platform 110 in a specified manner.

[0023] As described above, a data transmission link can be constructed based on the authentication link. The data transmission link can be used to transmit data between the target highway cloud platform 100 after identity authentication and the target data user platform 130 after identity authentication.

[0024] The data user platform 130 is used to obtain target road condition data from the highway cloud platform 110 through the data transmission link, generate road condition service information by combining the vehicle's current driving information, and forward the road condition service information to the data user terminal.

[0025] In this embodiment, the data user platform 130 can refer to a third-party application platform with data usage needs. For example, the data user platform 130 can be an operator data user platform 130, a map provider data user platform 130, a car manufacturer data user platform 130, etc.

[0026] It is understood that after the data transmission link is generated, the target data user platform 130 can obtain target road condition data from the highway cloud platform 110 through the data transmission link, generate road condition service information by combining it with the vehicle's current driving information, and forward the road condition service information to the data user terminal corresponding to the target data user platform 130. The vehicle's current driving information can be dynamic operating parameters collected and reported in real time by the data user terminal, including but not limited to: real-time geographical location, current speed, driving direction, planned route, vehicle type and size, destination information, etc. Traffic service information refers to information content with a clear service orientation generated after calculation based on the vehicle's real-time operating status and the surrounding traffic environment. For example, when the target traffic data shows congestion on a certain road segment, and the vehicle's current driving information indicates that the vehicle is heading towards that congested segment, the data user platform 130 can generate personalized traffic service information including congestion warnings, estimated delay time, and recommended detour routes.

[0027] This embodiment provides a cross-platform vehicle-road information interaction system, including: at least one highway cloud platform, a service management platform, and a data user platform; each highway cloud platform corresponds to a different geographical region; each highway cloud platform is used to process the initial road condition data of the highways in the corresponding region to obtain target road condition data; the service management platform is used to receive access request information sent by the data user platform, the access request information including a target identifier corresponding to the target highway cloud platform to be accessed; and performs access compliance determination on the target highway cloud platform and the data user platform according to the access request information, and performs identity authentication on the target highway cloud platform and the data user platform that pass the determination, in order to establish... An authentication link is established, and a data transmission link is constructed based on the authentication link. The authentication link is a secure association configuration relationship configured by the service management platform to realize identity authentication and access control between the target highway cloud platform and the data user platform. The data transmission link is used to transmit data between the target highway cloud platform and the data user platform. The data user platform is used to obtain the target road condition data from the target highway cloud platform through the data transmission link, generate road condition service information by combining the vehicle's current driving information, and forward the road condition service information to the data user terminal, thereby realizing the secure flow and scenario-based application of cross-platform data and realizing centralized service and distributed data circulation across road users and terminal users.

[0028] As an optional implementation, the highway cloud platform 110 includes an information service application module; the information service application module is used for: 1) Standardize the initial road condition data to obtain standardized road condition data.

[0029] In this embodiment, the information service application module can standardize the initial traffic data. Standardization refers to the process of converting the heterogeneous and disorganized initial traffic data into a unified and standardized data format. Standardization can include operations such as conversion, deduplication, and supplementation. For example, the initial traffic data can be converted, deduplicated, and supplemented to generate standardized traffic data for various connected applications.

[0030] 2) Obtain the preset data quality verification toolkit from the service management platform 120, and use the data quality verification toolkit to perform quality verification on the standardized traffic data, obtain the quality verification result, and send the quality verification result to the service management platform 120.

[0031] In this embodiment, the data quality verification toolkit can refer to a software image package pre-configured and distributed by the service management platform 120, which encapsulates data quality verification rules and algorithms. For example, the data quality verification toolkit may include preset data quality verification logic, including but not limited to: integrity verification (checking whether required fields are missing or data records are broken), accuracy verification (checking whether values ​​are within a reasonable range or whether there are logical contradictions), timeliness verification (checking whether the deviation between the data generation time and the current time exceeds a threshold), and consistency verification (checking whether the descriptions of the same object conflict in different data sources), etc.

[0032] Specifically, the preset data quality verification toolkit can be obtained from the service management platform 120, and executed in the local runtime environment to verify the quality of standardized traffic data, obtain the quality verification results, and send the results to the service management platform 120. The quality verification results can be quantitative results reflecting the quality status of the standardized traffic data, such as data pass rate, abnormal data list, missing field statistics, timeliness compliance rate, and data coverage scores for each road segment.

[0033] It should be explained that the data quality verification toolkit can be pre-configured on the data user platform 130 and sent by the data user platform 130 to the service management platform 120 as an image package.

[0034] 3) Determine the target road condition data based on the quality verification results.

[0035] Specifically, standardized traffic data that has passed quality verification can be identified as target traffic data. Target traffic data can be understood as the final data product that has undergone quality verification, meets preset quality standards, and can be directly used for external transmission and services. Compared to standardized traffic data, target traffic data offers further assurance in terms of quality and reliability. 4) Obtain the preset transmission image package from the service management platform 120, and use the transmission image package to transmit the target road condition data to the data user platform 130 through the data transmission link.

[0036] In this embodiment, the transmission image package refers to a software image package issued by the service management platform 120, which encapsulates data adaptation and transmission rules. It is a general adaptation package for specific types of data user platforms 130. The transmission image package can be a pre-configured image package on the data user platform 130, which is then sent to the service management platform 120 by the data user platform 130. The contents encapsulated in the transmission image package include, but are not limited to: data format conversion rules, data anonymization rules (anonymizing or obfuscating sensitive fields), data compression algorithms (reducing transmission bandwidth usage), encrypted transmission configuration, interface adaptation logic, and transmission strategy parameters (such as transmission frequency, batch size, and retry mechanism).

[0037] It is understood that a transmission image package can be obtained from the service management platform 120, and the target road condition data can be transmitted to the data user platform 130 via the data transmission link using the transmission image package. For example, the adaptation logic within the transmission image package can perform preprocessing on the target road condition data, such as format conversion, desensitization, compression, and encryption. Then, the processed data is sent to the data user platform 130 via the established data transmission link. The data transmission link refers to the secure communication channel established by the authentication link, with its two ends being the data user platform 130 of the target highway cloud platform 100, which has passed access compliance judgment and identity authentication. The data transmission link can employ encrypted transmission technology to transmit the target road condition data, ensuring the confidentiality, integrity, and availability of the target road condition data during transmission.

[0038] As an optional implementation method, Figure 2 This embodiment provides a structural block diagram of a service management platform, such as... Figure 2 As shown, the service management platform 120 includes a service configuration management module 121. The service configuration management module 121 can refer to a functional unit deployed within the service management platform 120, responsible for receiving access applications, conducting compliance reviews, configuring links, and scheduling. The service configuration management module 121 is used for: 1) Receive the first access application information of the target highway cloud platform 100; based on the first access application information, determine the access compliance of the target highway cloud platform 100 according to the first compliance determination rule, and obtain the first determination result.

[0039] In this embodiment, the service configuration management module 121 can receive the first access application information from the target highway cloud platform 100. The first access application information can refer to the set of application information submitted by the target highway cloud platform 100 to the service configuration management module 121 to prove its access qualifications and capabilities. The first access application information typically includes, but is not limited to: platform entity qualification information, platform technical architecture information (such as platform deployment method, data processing capabilities, interface specification description), data resource description (such as coverage of road segments, data type, data update frequency), and security protection scheme (such as data encryption measures, access control policies, security audit mechanisms), etc.

[0040] As described above, after obtaining the first access application information, the access compliance of the target highway cloud platform 100 can be determined according to the first compliance determination rules to obtain the first determination result. The first compliance determination rules refer to the set of determination rules pre-configured by the service configuration management module 121 specifically used to review the access qualifications of the highway cloud platform 110. The first compliance determination rules can be formulated by the service management platform 120 based on factors such as data security regulations, industry regulatory requirements, and platform operation strategies. For example, the first compliance determination rules may include: rules for the integrity of the main entity's qualifications (e.g., checking whether the mandatory qualification documents of the highway cloud platform 110 are complete and valid), rules for meeting technical capability standards (checking whether the technical architecture of the highway cloud platform 110 meets the minimum performance indicators and security standards), rules for data resource compliance (checking whether the data source of the highway cloud platform 110 is legal and whether the data content involves sensitive information requiring special handling), and rules for matching security policies (checking whether the security assurance plan of the highway cloud platform 110 complies with the platform's mandatory security baseline), etc. The first compliance determination rules can be deployed in the service configuration management module 121 in the form of executable code, configuration tables, or decision trees.

[0041] As described above, access compliance can be understood as the comprehensive state of the target highway cloud platform 100 in terms of qualifications, technology, data, security, and other dimensions, meeting preset access standards. The judgment process may involve comparing and verifying each item in the first access application information against the corresponding clauses in the first compliance judgment rules, recording the pass status of each verification, and calculating the final judgment conclusion according to a preset scoring mechanism or a veto mechanism. The output first judgment result refers to the conclusion reflecting whether the target highway cloud platform 100 has passed the access compliance judgment. For example, the first judgment result could be: the target highway cloud platform 100 has passed the access compliance judgment.

[0042] 2) Receive the second access application information from the data user platform 130; based on the second access application information, determine the access compliance of the data user platform 130 according to the second compliance determination rules, and obtain the second determination result.

[0043] In this embodiment, the service configuration management module 121 can receive second access application information from the data user platform 130. This second access application information can be a set of application information submitted by the data user platform 130 to the service configuration management module 121 to prove its access eligibility. For example, the second access application information typically includes, but is not limited to: the data user platform 130's qualification information (such as business license, data processing related qualifications, etc.), a description of the data usage scenario (such as specific application scenarios, usage purpose, and expected user scale), technical integration capability information (such as system interface specifications, data receiving and processing capabilities, and network security protection level), and data security commitments (such as data storage period, data destruction mechanism, user privacy protection measures, and commitment to prohibit secondary resale).

[0044] As described above, after obtaining the second access application information, the access compliance of the data user platform 130 can be determined according to the second compliance determination rules to obtain the second determination result. The second compliance determination rules refer to the set of determination rules pre-configured by the service configuration management module 121 specifically used to review the access qualifications of the data user platform 130. The second compliance determination rules can be formulated by the service management platform 120 based on factors such as data security regulations, personal information protection laws, industry regulatory requirements, and platform operation strategies. For example, the second compliance determination rules may include: rules on the legality of the entity's qualifications (checking whether the data user platform 130 is a legally existing corporate entity), rules on the compliance of the usage scenario (checking whether the purpose of data use is within the permitted scope, excluding illegal, non-compliant, or authorized usage scenarios), rules on the adaptation of technical capabilities (checking whether the data user platform 130 has the technical conditions for securely receiving and processing data), and rules on the enforceability of security commitments (checking whether the data security commitments are specific, verifiable, and accountable). The second compliance determination rules are also deployed in the service configuration management module 121 in the form of executable code, configuration tables, or decision trees.

[0045] As described above, after receiving the second access application information submitted by the data user platform 130, the service configuration management module 121 calls the second compliance judgment rules to determine the access compliance of the data user platform 130. The judgment process may involve comparing and verifying each item in the second access application information with the corresponding clause in the second compliance judgment rules, recording the pass status of each verification, and determining the second judgment result according to a preset scoring mechanism or a veto mechanism. The second judgment result may be conclusive information reflecting whether the data user platform 130 passes the access compliance judgment. For example, the second judgment result may be that the data user platform 130 passes the access compliance judgment.

[0046] 3) Based on the first and second judgment results, the highway cloud platform 110 and the data user platform 130 that have passed the access compliance judgment are determined.

[0047] Specifically, when both the first and second judgment results are passed, the service configuration management module 121 can identify the target highway cloud platform 100 and the data user platform 130 as paired platforms that have passed the access compliance judgment. If the judgment result of either party is "failed", the pairing relationship will not be established. It should be noted that the service configuration management module 121 can also record the reason for the failure of either party's judgment and provide feedback to the corresponding applicant.

[0048] 4) The service configuration management module 121 is also used to build a data transmission link based on the authentication link after the authentication link is established.

[0049] Specifically, based on the successful establishment of the authentication link, a communication channel for actual data transmission is constructed using the security parameters and configuration information contained in the established authentication link. For example, the specific construction process includes: extracting security parameters such as encryption keys, transmission protocol types, port mapping rules, and session timeout settings from the authentication link; and negotiating and establishing an encrypted data transmission link between the target highway cloud platform 100 and the data user platform 130 based on these security acceptances.

[0050] As an optional implementation method, such as Figure 2 As shown, the service management platform 120 includes an authentication management module 122, a data quality monitoring module 123, and a service statistics module 124; 1) The authentication management module 122 is used to authenticate the target highway cloud platform 100 and the data user platform 130 that have passed the access compliance judgment in order to establish an authentication link.

[0051] In this embodiment, the authentication management module 122 can be a functional module for performing functions such as identity authentication, credential management, permission configuration, and security policy execution. After the target highway cloud platform 100 and the data user platform 130 pass the access compliance determination, the authentication management module 122 can perform identity authentication on the target highway cloud platform 100 and the data user platform 130 that have passed the access compliance determination. Identity authentication refers to the technical process by which the authentication management module 122 verifies and confirms the true identities of the target highway cloud platform 100 and the data user platform 130. The purpose of identity authentication is to ensure that the entities connected at both ends of the authentication link are indeed legitimate platforms that have undergone compliance review.

[0052] For example, specific implementations of identity authentication include, but are not limited to: two-way authentication based on digital certificates, two-way authentication based on shared keys (such as one party generating a random number challenge code, the other party using a pre-shared key to sign or encrypt it and return it, and the verifier verifying the correctness of the response), etc.

[0053] It is understood that after successful identity authentication, an authentication link can be established. This authentication link refers to the secure association configuration relationship configured by the authentication management module 122 to achieve identity authentication and access control between the target highway cloud platform 100 and the data user platform 130. For example, the authentication link may include the following configuration elements: allocation and management of authentication credentials (e.g., allocating long-term valid identity certificates or short-term valid access tokens to both parties and establishing a credential update and revocation mechanism), configuration of access permissions (e.g., specifying the data types, data ranges, data time periods, and call frequency limits that the data user platform 130 can access), binding of security policies (e.g., enforcing encrypted transmission protocol versions, session timeouts, detection thresholds and handling rules for abnormal access behavior), and recording and auditing rules for access logs (e.g., recording the time, subject, result, and verification address of each identity verification).

[0054] 2) The data quality monitoring module 123 is used to receive the quality verification results sent by the target highway cloud platform 100, evaluate the quality verification results, and generate alarm information when the evaluation result is unsuccessful.

[0055] Specifically, the data quality monitoring module 123 can receive the quality verification results sent by the target highway cloud platform 100 and evaluate the quality verification results. For example, it can compare and analyze the received quality verification results with the preset quality evaluation standards to determine whether the quality level of the current target road condition data meets the requirements. The quality evaluation standards can be pre-configured by the data quality monitoring module 123. For example, the quality evaluation standards may include: minimum pass rate threshold, key indicator compliance requirements (such as: vehicle speed data coverage of core road sections, timeliness tolerance limit (such as: data delay must not exceed 5 minutes), abnormal data ratio limit (etc.).

[0056] It is known that when the evaluation result is unsatisfactory, an alarm message can be generated. The alarm message can be used to notify relevant operation and maintenance personnel or management personnel that the current road condition data quality is abnormal and needs to be intervened.

[0057] 3) The service statistics module 124 is used to perform statistics on the data service calls between the target highway cloud platform 100 and the data user platform 130.

[0058] In this embodiment, the data service call status refers to the various behavioral records generated during the transmission of target road condition data and service interaction between the target highway cloud platform 100 and the data user platform 130 through the established data transmission link. The service statistics module 124 can perform statistics on the data service call status between the target highway cloud platform 100 and the data user platform 130 to obtain statistical results, thereby providing data support for the operational decision-making of the service management platform 120.

[0059] As an optional implementation method, such as Figure 2 As shown, the service management platform 120 includes a service tool library module 125; the service tool library module 125 may include a service tool package management submodule 1251, a data quality verification tool package management submodule 1252, and a system upgrade tool package management submodule 1253; Among them, the service toolkit management submodule 1251 is used to manage the transmission image package for the target highway cloud platform 100 to download and install; the data quality verification toolkit management submodule 1252 is used to manage the data quality verification toolkit for the target highway cloud platform 100 to download and install; and the system upgrade toolkit management submodule 1253 is used to provide remote upgrade services for each toolkit to the target highway cloud platform 100.

[0060] Specifically, the target highway cloud platform 100 can initiate a download request to the service toolkit management submodule 1251 based on the type of the data user platform 130 it connects to. Upon receiving the download request, the service toolkit management submodule 1251 can send a transmission image package to the authenticated target highway cloud platform 100, enabling the target highway cloud platform 100 to obtain the corresponding transmission image package. Similarly, the target highway cloud platform 100 can initiate a download request to the data quality verification toolkit management submodule 1252 based on the type of the data user platform 130 it connects to. Upon receiving the download request, the data quality verification toolkit management submodule 1252 can send a data quality verification toolkit to the authenticated target highway cloud platform 100, enabling the target highway cloud platform 100 to obtain the corresponding data quality verification toolkit.

[0061] It should be noted that both the transmission image package and the data quality verification toolkit are sent by the data user platform 130 to the service toolkit management submodule 1251 and the data quality verification toolkit management submodule 1252. After the data transmission link is established, when the data user updates the corresponding transmission image package and data quality verification toolkit, the service toolkit management submodule 1251 and the data quality verification toolkit management submodule 1252 can be updated synchronously, and the updated transmission image package and data quality verification toolkit will be sent to the target highway cloud platform 100.

[0062] It is understood that the system upgrade toolkit management submodule 1253 is used to provide remote upgrade services for various toolkits to the target highway cloud platform 100. This remote upgrade service refers to the system upgrade toolkit management submodule 1253 providing update services for each toolkit to the target highway cloud platform 100 via a network channel without relying on on-site maintenance personnel. For example, the system upgrade toolkit management submodule 1253 can provide remote upgrade services for transmission image packages and data quality verification packages to the target highway cloud platform 100. It should be explained that the system upgrade toolkit management submodule 1253 can also provide remote upgrade services for other types of toolkits of the target highway cloud platform 100.

[0063] Figure 3 This is a schematic diagram of the structure of a cross-platform vehicle-road information interaction system provided in this embodiment, as shown below. Figure 3As shown, the system mainly includes a service management platform, a highway cloud platform, and a data user platform (service objects). The service management platform is primarily responsible for service configuration management, service tool management, authentication services, data quality monitoring, and service statistics between the highway platform's information service module and data user platforms such as vehicle manufacturers. The service management platform is internally divided into five functional modules. The service configuration management module is responsible for platform access configuration, user permission management, and data distribution control. It includes: Regional management: the function of dividing and managing the geographical area or administrative division to which the highway cloud platform belongs, used to implement regional data access policy configuration and resource scheduling; User management: the function of account registration, information maintenance, permission allocation, and status management for data user platforms (i.e., service objects) applying for access; Data distribution control: the function of configuring and regulating the distribution strategy of target road condition data to various data user platforms, including distribution scope setting, distribution frequency control, and priority scheduling. The service configuration management module interacts with the highway cloud platform's information service application module through a management flow (green solid line) to realize the distribution and configuration synchronization of service policies on the cloud platform side. The Service Tool Library module refers to a functional unit responsible for the centralized storage, version management, and distribution scheduling of various toolkits. It comprises three sub-modules: the Automotive Enterprise Service Toolkit Management sub-module, which manages the transmission image packages for automotive enterprise data user platforms; the Data Quality Verification Toolkit Management sub-module, which manages data quality verification toolkits used for data quality monitoring; and the System Upgrade Toolkit Management sub-module, which manages system upgrade toolkits used for cloud platform system updates. The Service Tool Library module provides toolkit download and installation services to the information service application modules of the highway cloud platform through a management flow (green solid line), enabling each highway cloud platform to locally perform data adaptation, quality verification, and system upgrades.

[0064] The authentication management module includes: Key Management: This refers to the full lifecycle management of keys used for encrypted transmission and authentication, including generation, distribution, updating, and revocation; Access Request: This refers to receiving and processing access permission requests from data user platforms, approving or automatically authorizing based on preset policies. The authentication management module interacts with the information service application module of the highway cloud platform through the management flow to complete the establishment of identity authentication and authorization links between platforms. The data quality monitoring module includes: Report Generation: This refers to the function of generating data quality evaluation reports based on received quality verification results and according to preset evaluation standards; Report Subscription: This refers to providing quality report subscription services for managers or maintenance personnel, supporting customized report content by period, indicator, road segment, etc.; Report Sending: This refers to the function of sending the generated quality reports to subscribers via email, SMS, push notifications, etc. The data quality monitoring module interacts with the information service application of the highway cloud platform through the management flow, receiving quality verification results and providing feedback on quality monitoring information. The service statistics module includes: Usage Reception: This refers to the function of receiving service call records and usage information reported by various highway cloud platforms; Usage Statistics: This refers to the function of aggregating and calculating the received usage data, generating reports, and displaying visualizations. The service statistics module interacts with the information service applications of the highway cloud platform through the management flow to obtain service call data.

[0065] As described above, the highway cloud platform includes an information service application module. The functions of this module can include system management, management service interfaces, and business service interfaces. System management includes configuration management, version management, static data management, and service statistics. The management service interface includes service authentication (uploading / downloading security certificates to the service management platform and establishing an authentication link with vehicle manufacturer platforms) and data quality reporting (reporting data quality status to the service management platform). The business service interface provides real-time, standardized, and high-quality data services to different vehicle manufacturers (downloading and installing image packages from the service management platform). The business service interface internally deploys multiple image packages, corresponding to different types of service objects: Operator A image package: a transmission image package customized for operator A-type data user platforms; Map Provider A image package: a transmission image package customized for map provider (map service provider) A-type data user platforms; Vehicle Manufacturer Platform Service Provider A image package: a transmission image package customized for vehicle manufacturer platform service provider A-type data user platforms; and other image packages: transmission image packages customized for other types of data user platforms. The information service application module can also perform data cleaning and data quality verification functions. Data cleaning includes transforming, deduplicating, and supplementing raw data to generate standardized data for various network applications. Data quality verification includes performing data quality verification analysis on the data generated by the data cleaning module (downloading and installing the image package from the service management platform).

[0066] As described above, the data user platform (service recipient) includes service recipients such as operator software development kits (SDKs), map providers, and vehicle manufacturers' platforms. The data user platform (service recipient) interacts with the information service applications at the cloud platform layer through business flows (orange solid line) to receive target traffic data. User mobile terminals receive traffic service information from operator SDKs, map providers, or vehicle manufacturers' platforms through business flows and present it to end users in the form of visual interfaces or voice broadcasts. In-vehicle intelligent terminals receive traffic service information from vehicle manufacturers' platforms or user mobile terminals through business flows to provide drivers with driving assistance and travel guidance services.

[0067] Example 2 Figure 4 This is a flowchart illustrating a cross-platform vehicle-road information interaction method provided in Embodiment 2 of this disclosure. The method is applied to a cross-platform vehicle-road information interaction system, which includes at least one highway cloud platform, a service management platform, and a data user platform; each highway cloud platform corresponds to a different geographical region. For example... Figure 4 As shown, the method includes: S210 and each expressway cloud platform process the initial road condition data of the corresponding expressway areas to obtain target road condition data.

[0068] In this embodiment, each highway cloud platform distributed in different regions can perform data acquisition and processing operations independently. Each highway cloud platform acquires initial road condition data for the highways within its corresponding region. This initial road condition data originates from various heterogeneous data sources, such as roadside sensing devices and meteorological monitoring devices. Since the initial road condition data suffers from issues such as inconsistent formats and time bases, each highway cloud platform can perform data processing on the collected initial road condition data (e.g., data cleaning, format standardization, and quality verification) to determine the target road condition data.

[0069] S220. The service management platform receives access application information sent by the data user platform. The access application information includes the target identifier corresponding to the target highway cloud platform to be accessed. Based on the access application information, the service management platform performs access compliance judgment on the target highway cloud platform and the data user platform. For the target highway cloud platform and the data user platform that pass the judgment, the platform performs identity authentication to establish an authentication link. Based on the authentication link, a data transmission link is constructed. The authentication link is a secure association configuration relationship configured by the service management platform to realize identity authentication and access control between the target highway cloud platform and the data user platform. The data transmission link is used to transmit data between the target highway cloud platform and the data user platform.

[0070] It is known that when a data user platform needs to obtain target traffic data, it sends an access request to the service management platform. This access request includes the target identifier corresponding to the target highway cloud platform to be accessed, clearly indicating which region's highway data the data user platform wants to obtain.

[0071] As described above, based on the access application information, the service management platform identifies the highway cloud platform corresponding to the target identifier as the target highway cloud platform. It then performs an access compliance assessment on both the target highway cloud platform and the data user platform, reviewing whether both meet the preset access standards. Only when both parties pass the assessment does the service management platform authenticate their identities, verify their true identities, and establish an authentication link. The authentication link is a secure association configuration relationship configured by the service management platform to achieve identity authentication and access control between the target highway cloud platform and the data user platform.

[0072] As described above, based on the establishment of the authentication link, the service management platform further constructs a data transmission link. This data transmission link is used for encrypted transmission between the target highway cloud platform and the data user platform to ensure the security of the target road condition data during transmission.

[0073] S230: The data user platform obtains target road condition data from the target highway cloud platform through the data transmission link, generates road condition service information by combining the vehicle's current driving information, and forwards the road condition service information to the data user terminal.

[0074] Specifically, after identity authentication, the data user platform can request and obtain target road condition data from the target highway cloud platform via the data transmission link. The data user platform can also collect the vehicle's current status information. After obtaining the target road condition data, the data user platform can integrate the target road condition data with the vehicle's current driving information, and combine dynamic parameters such as the vehicle's real-time location, speed, and planned route to generate personalized road condition service information tailored to specific vehicle scenarios.

[0075] It should be explained that the data user platform can forward the generated traffic service information to the data user terminal, and the terminal device will then present the traffic service information to the user.

[0076] This embodiment provides a cross-platform vehicle-road information interaction method, including: each highway cloud platform processes the initial road condition data of the corresponding area of ​​the highway to obtain target road condition data; the service management platform receives access application information sent by the data user platform, the access application information including the target identifier corresponding to the target highway cloud platform to be accessed; and performs access compliance judgment on the target highway cloud platform and the data user platform according to the access application information, performs identity authentication on the target highway cloud platform and the data user platform that pass the judgment to establish an authentication link, and constructs a data transmission link based on the authentication link; the authentication link is a secure association configuration relationship configured by the service management platform to realize identity authentication and access control between the target highway cloud platform and the data user platform; the data transmission link is used to transmit data between the target highway cloud platform and the data user platform; the data user platform obtains the target road condition data from the target highway cloud platform through the data transmission link, generates road condition service information in combination with the current driving information of the vehicle, and forwards the road condition service information to the data user terminal, realizing centralized service and distributed data circulation across road users and across terminal users.

[0077] As an optional implementation, the highway cloud platform includes an information service application module; the method further includes: 1) The information service application module performs standardization processing on the initial traffic data to obtain standardized traffic data.

[0078] In this embodiment, initial traffic data can be obtained through the information service application module. This initial traffic data originates from heterogeneous acquisition devices and transmission channels, thus exhibiting issues such as inconsistent formats, inconsistent timestamps, and spatial coordinate deviations. The information service application module can perform standardization processing on this initial traffic data, such as data format conversion, encoding rule unification, timestamp calibration, spatial coordinate transformation, field mapping, and reorganization, converting the initial traffic data into a unified and standardized data format to obtain standardized traffic data.

[0079] 2) The information service application module obtains a preset data quality verification toolkit from the service management platform, uses the data quality verification toolkit to perform quality verification on the standardized traffic data, obtains the quality verification result, and sends the quality verification result to the service management platform.

[0080] It is known that the information service application module can obtain a pre-set data quality verification toolkit from the service management platform. This toolkit can be configured by the data user platform and sent to the service management platform for storage.

[0081] As described above, the information service application module can use a data quality verification toolkit to verify the quality of standardized traffic data and obtain the verification results. These results are then sent to the service management platform for data quality monitoring and evaluation.

[0082] 3) The information service application module determines the target traffic data based on the quality verification result; and obtains a preset transmission image package from the service management platform, and uses the transmission image package to transmit the target traffic data to the data user platform through the data transmission link.

[0083] It is known that after obtaining the quality verification results, the target road condition data that meets the quality standards can be determined based on these results. A pre-defined transmission image package is obtained from the service management platform. This transmission image package can be configured by the data user platform and sent to the service management platform for storage.

[0084] As described above, the information service application module transmits the target traffic data to the data user platform via the data transmission link according to the transmission mirror packet.

[0085] For example, it can receive data on traffic incidents, accidents, and control, and has functions such as standardized generation of business data and data quality monitoring; it can deploy lightweight image packages for various car manufacturers, operators, and map providers. The image packages are developed by the data users according to their data usage needs, and mainly realize functions such as business data retrieval and cleaning, and location matching; the information service application and service management platform can connect the service management link to realize the interaction of management data such as authentication and version; the information service application and the cloud platforms of car manufacturers, operators, and map providers can directly provide standardized and highly reliable connected business data.

[0086] As an optional implementation, the service management platform includes a service configuration management module; the method further includes: 1) The service configuration management module receives the first access application information of the target highway cloud platform; and based on the first access application information, determines the access compliance of the target highway cloud platform according to the first compliance determination rule, and obtains the first determination result.

[0087] Specifically, the service configuration management module can receive the first access application information submitted by the target highway cloud platform and review the access compliance of the target highway cloud platform according to the preset first compliance judgment rules. The review dimensions include the completeness of the entity's qualifications, the adequacy of technical capabilities, the legality of the data source, and the degree of security policy matching. After the review is completed, the first judgment result can be output, which can reflect whether the target highway cloud platform has the access qualifications as a data provider.

[0088] 2) The service configuration management module receives the second access application information from the data user platform; and based on the second access application information, performs access compliance judgment on the data user platform according to the second compliance judgment rule to obtain the second judgment result.

[0089] The service configuration management module receives a second access application from a data user platform. This application includes the platform's qualifications, a description of the data usage scenario, technical integration capabilities, and data security commitments. Based on preset second compliance judgment rules, the module reviews the access compliance of the data user platform. The review dimensions include the legality of the platform's qualifications, compliance of the usage scenario, technical capability compatibility, and the enforceability of the security commitments. Upon completion of the review, a second judgment result is output, reflecting whether the data user platform is qualified to act as a data consumer.

[0090] 3) Based on the first judgment result and the second judgment result, the service configuration management module determines the target highway cloud platform and data user platform that pass the access compliance judgment.

[0091] Specifically, after obtaining the first and second judgment results, the service configuration management module can make a comprehensive judgment on both results. Only when both the first and second judgment results are passed will the service configuration management module determine the target highway cloud platform and the data user platform as a paired platform that has passed the access compliance judgment, allowing them to enter the subsequent identity authentication process.

[0092] It should be noted that if either party determines that the pairing relationship is not successful, the pairing relationship will not be established, and the service configuration management module can record the reason for the failure and provide feedback to the corresponding applicant.

[0093] 4) After the authentication link is established, the service configuration management module constructs the data transmission link based on the authentication link.

[0094] It is known that once the service configuration management module has completed identity authentication and established the authentication link, it can build a data transmission link based on the authentication link.

[0095] For example, the service configuration management module can implement the following functions: regional management: compliance determination of access to the highway cloud platform and configuration of service regions; user management: compliance determination of access to data user platforms such as car manufacturers; data distribution control: authentication connection of data links between the highway cloud platform and car manufacturer platforms.

[0096] As an optional implementation, the service management platform includes an authentication management module, a data quality monitoring module, and a service statistics module; the method further includes: 1) The authentication management module performs identity authentication on the target highway cloud platform and the data user platform that have passed the access compliance determination in order to establish the authentication link.

[0097] It is understood that the authentication management module can obtain pairing information between the target highway cloud platform and the data user platform, which have passed the access compliance assessment, and perform identity authentication on both parties. Identity authentication employs methods such as two-way digital certificate authentication to verify the true identities of both parties. After successful identity authentication between the target highway cloud platform and the data user platform, the authentication management module can configure authentication credentials, access permissions, security policies, and audit rules to establish an authentication link. This authentication link represents the secure association configuration relationship between the two parties, used to implement identity authentication and access control. For example, the authentication management module can issue security certificates and perform identity authentication on the highway cloud platform and the vehicle manufacturer platform.

[0098] 2) The data quality monitoring module receives the quality verification result sent by the target highway cloud platform, evaluates the quality verification result, and generates an alarm message when the evaluation result is unsuccessful.

[0099] Specifically, the data quality monitoring module can receive quality verification results sent by the information service application module of the target highway cloud platform. The data quality monitoring module can evaluate these results according to preset quality evaluation standards to determine whether the target road condition data meets the requirements for external transmission. If the evaluation result is satisfactory, the target road condition data is transmitted to the data user platform via the data transmission link; if the evaluation result is unsatisfactory, the data quality monitoring module generates an alarm message to notify that the current data quality is abnormal.

[0100] For example, the functions of the data quality monitoring module may include: quality monitoring and evaluation: monitoring and evaluating the service data quality of the highway cloud platform; alarms and work orders: generating data quality alarm maintenance work orders for the highway cloud platform; clearing and settlement (reservation): service usage records, fee settlement and management, etc.

[0101] 3) The service statistics module performs statistics on the data service calls between the target highway cloud platform and the data user platform.

[0102] It is known that the service statistics module can receive and record service call information generated during data interaction between the target highway cloud platform and the data user platform via the data transmission link, such as call time, data type, data volume, response status, and resource consumption. The service statistics module aggregates, calculates, analyzes trends, and generates reports based on this call information, forming statistical results that reflect the actual operational status of the data service.

[0103] As an optional implementation, the service management platform includes a service tool library module; the service tool library module includes a service toolkit management submodule, a data quality verification toolkit management submodule, and a system upgrade toolkit management submodule; the method further includes: 1) The service toolkit management submodule manages the transmission image package for download and installation by the target highway cloud platform.

[0104] It is known that the service toolkit management submodule can perform operations such as storage, version management, and distribution scheduling on the transport image package. The target highway cloud platform, based on the type of data user platform it is connected to, initiates a download request to the service toolkit management submodule. After obtaining the corresponding transport image package, it loads and installs it in its local runtime environment, thereby gaining the ability to adapt and transmit data to that data user platform.

[0105] 2) The data quality verification toolkit management submodule manages the data quality verification toolkit for download and installation by the target highway cloud platform.

[0106] Specifically, the data quality verification toolkit management submodule can perform operations such as storage, version management, and distribution scheduling on the data quality verification toolkit. The target highway cloud platform can send a download request to the data quality verification toolkit management submodule, obtain the image package, load and execute it in the local runtime environment, perform automated quality verification on standardized road condition data, generate quality verification results, and feed them back to the data quality monitoring module of the service management platform.

[0107] 3) The system upgrade toolkit management submodule provides remote upgrade services for each toolkit of the target highway cloud platform.

[0108] Specifically, the system upgrade toolkit management submodule can perform operations such as storage, version management, and canary release of the toolkits required by the target highway cloud platform. This submodule can also push upgrade availability notifications to the target highway cloud platform and distribute upgrade toolkits, allowing the target highway cloud platform to execute the upgrade procedure locally on the corresponding toolkits.

[0109] This embodiment provides a cross-platform vehicle-road information interaction method, comprising: each of the highway cloud platforms processing initial road condition data of the corresponding region's highways to obtain target road condition data; the service management platform receiving access application information sent by the data user platform, the access application information including a target identifier corresponding to the target highway cloud platform to be accessed; and performing access compliance determination on the target highway cloud platform and the data user platform according to the access application information, authenticating the target highway cloud platform and the data user platform that pass the determination to establish an authentication link, and constructing a data transmission link based on the authentication link; the data user platform obtaining the target road condition data from the target highway cloud platform through the data transmission link, generating road condition service information in combination with the vehicle's current driving information, and forwarding the road condition service information to the data user terminal. The aforementioned technical solution involves a highway cloud platform collecting business data such as events, accidents, and management data. It develops information service applications embedded with image packages from different operators / service providers, enabling business data interconnection and interoperability with data user platforms such as vehicle manufacturers, operators, and map providers. These platforms receive data and provide data services to the onboard terminals of intelligent connected vehicles. A unified service support management platform is constructed to achieve functions such as service configuration management, service tool management, authentication services, data quality monitoring, and service statistics. It also facilitates management data interaction with information service applications from data providers and data user platforms. This overcomes the limitations of current one-to-one interface debugging between vehicle-side and road-side systems, which is complex and unable to support unified services across provinces and users. It achieves centralized services and distributed data circulation across road users and terminal users.
