[0002] In modern automobile manufacturing, the installation of intelligent connected components has become an indispensable part in order to achieve more intelligent functions. During installation, these components upload a component traceability code and uniquely associate the vehicle and the equipment to ensure the traceability and management of each component. However, in the actual installation process, various technical problems may be encountered, such as component failure, human error leading to incorrect component information, or even components failing to communicate normally.

[0003] Existing technical methods mainly include vehicle initial electrical testing and post-production functional testing. Initial electrical testing verifies the physical connections and basic functions of components through a series of electrical tests, while functional testing conducts comprehensive functional tests after the vehicle rolls off the production line to ensure that all vehicle functions meet standards. However, these methods can only identify physical and functional abnormalities of components to a certain extent, and cannot detect data errors related to the vehicle-to-the-cloud. If these problems lead to the failure of the vehicle's connectivity functions, they could even cause more serious safety issues. Summary of the Invention

The identity verification request is used to enable the cloud to perform an identity verification step based on the identity verification request. The identity verification result includes a component existence verification result, a component reuse verification result, a component data validity verification result, and a component data integrity verification result. The component existence verification result is used to characterize the existence status of each component identity information in the component registration database queried by the cloud. The component reuse verification result is used to characterize the status of each component identity information being used by other vehicles queried by the cloud. The component data validity verification result is used to characterize whether the format of each component identity information conforms to a preset format specification verified by the cloud. The component data integrity verification result is used to characterize the existence status of key information in each component identity information checked by the cloud.

[0024] The embodiments of the present invention will be described below with reference to the accompanying drawings and specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0025] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0026] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the invention.

[0027] The term "and / or" used in this application describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the related objects before and after it are in an "or" relationship.

[0028] First, it should be noted that this application applies to the off-line testing of connected components in vehicles. Therefore, the "installed components" mentioned below include components already installed in the vehicle to be tested for supporting connected functions. In the embodiments of this application, the "line" in terms such as "off-line" and "return to line" refers to the production line or maintenance line.

[0029] Figure 1 This is a schematic diagram illustrating an exemplary system architecture as shown in an exemplary embodiment of this application.

[0030] Reference Figure 1 As shown, the system architecture may include a vehicle under test 110, a computer device 120, and a cloud 130. The computer device 120 acquires the initial component information and component identity information of the installed components in the vehicle under test 110, and writes the initial component information into the vehicle's infotainment system. In response to the completion of writing the initial component information into the vehicle's infotainment system, the computer device 120 controls each installed component to communicate with the cloud 130 to obtain the component connectivity status. If the connectivity status of each component is normal, the computer device 120 controls the uploading of the component identity information of each installed component to the cloud 130, and receives the identity verification result fed back by the cloud 130. This identity verification result is obtained by the cloud based on the component identity information. If the identity verification result is correct, it is determined that the vehicle's offline testing is normal, and the computer device 120 controls the vehicle under test 110 to be taken offline. The aforementioned computer equipment 120 may be at least one of a microcomputer, embedded computer, network computer, industrial control computer, etc. The computer equipment is equipped with computer software, instructions, scripts or plug-in tools for performing vehicle off-line inspection, and is connected to equipment and related testing devices for performing vehicle off-line inspection; the aforementioned vehicle to be inspected 110 refers to a vehicle that has been assembled on the production line and is ready to be off-line, or a vehicle that is being maintained and repaired on the production line.

[0031] In a schematic manner, computer device 120 acquires the initial information and identity information of the components installed in the vehicle under test 110, and writes the initial information into the vehicle's infotainment system. After writing, it controls each installed component to communicate with the cloud 130 to obtain the component connectivity status. If all component connectivity statuses are normal, the component identity information is uploaded to the cloud 130 for identity verification. If the verification result is correct, the vehicle's offline testing is deemed normal, and the vehicle under test 110 is taken offline. This method, after completing the initial information writing, controls each installed component to communicate with the cloud, verifying the communication capability between the components and the cloud, ensuring the stability and reliability of data transmission. If all components are connected normally, identity verification is performed in the cloud, ensuring the legality of the component identity information and the integrity of the data. This avoids network connectivity malfunctions caused by data errors. Through multi-layer detection and verification mechanisms, and the introduction of a cloud data verification mechanism, the reliability of data transmission is ensured, network connectivity malfunctions caused by data errors are avoided, the accuracy and completeness of component information detection are improved, the possibility of human error is reduced, the risk of problematic vehicles leaving the network is lowered, and production quality and user satisfaction are improved.

[0032] Figure 2 This is a flowchart illustrating an exemplary embodiment of the present application of a vehicle off-line inspection method, which can be used in... Figure 1 It can be executed in the implementation environment described above, but it can also be implemented in other implementation environments. No specific limitations are imposed on the aforementioned implementation environments here. (See also...) Figure 2 As shown, the flowchart of the vehicle off-line inspection method includes at least steps S210 to S240, which are described in detail below:

[0033] In step S210, the initial information and identity information of the components installed in the vehicle to be tested are obtained, and the initial information of the components is written into the vehicle system.

[0034] In one embodiment of this application, before obtaining the initial information and identity information of the components installed in the vehicle to be tested, when the assembled vehicle to be tested enters the initial testing station, a component assembly re-inspection request is generated and displayed on the terminal. The component assembly re-inspection request is used to request relevant technicians to re-inspect the installed components in the assembled vehicle to be tested, including the stability of installation, the firmness of physical connection and the correctness.

[0035] If the received re-inspection feedback message indicates that the assembly re-inspection is correct, the steps of obtaining the initial information and identification information of the installed components in the vehicle to be inspected are executed. If the received re-inspection feedback message indicates an assembly connection error, an error transmission command is generated and sent to the vehicle transmission device, generating an assembly error pending processing request and displaying the request. The error transmission command is used to instruct the vehicle transmission device to transmit the vehicle to be inspected to the error processing area. The aforementioned initial component information includes, but is not limited to, the vehicle identification number (VIN), equipment certificate, production date, and serial number. The component identification information includes the connected component device ID (PDID). The error processing area is a temporary storage area for vehicles that have detected errors during vehicle off-line inspection. These vehicles can be transported through the production line. After being displayed on the terminal, relevant technical personnel will make processing decisions and perform re-maintenance based on the displayed cause of the error, significantly reducing the risk of problematic vehicles leaving the vehicle.

[0036] In one embodiment of this application, initial component information is written into the vehicle infotainment system using sensors and scanning devices, such as barcode scanners and RFID readers. An RFID (Radio-Frequency Identification) reader is a device used to read and write RFID tag information. RFID technology utilizes radio waves for contactless data transmission and is widely used in logistics, manufacturing, and other fields. Initial information about the components installed in the vehicle to be inspected is obtained, including but not limited to the vehicle identification number (VIN), equipment certificate, production date, and serial number. This information is transmitted to the vehicle infotainment system via an in-vehicle network (such as CAN bus or Ethernet). Upon receiving the information, the vehicle infotainment system performs data parsing and verification to ensure the information is formatted correctly, completely, and accurately. The verified information is then stored in a configuration database, generating corresponding records.

[0037] In step S220, in response to the completion of writing the initial information of the components into the vehicle system, the system controls each installed component to communicate with the cloud to obtain the component connectivity status.

[0038] In one embodiment of this application, the component connectivity status is used to characterize the communication connection status between the component and the cloud.

[0039] In one embodiment of this application, the system controls each installed component to communicate with the cloud. Obtaining the component connectivity status includes the vehicle system generating a cloud communication request and sending it to each installed component. Each installed component configures its corresponding communication interface according to a preset network configuration information file and performs a handshake communication with the cloud through that interface. The handshake communication includes the component sending a handshake request to the cloud. This request contains a list of encryption suites supported by the client, a random number, and other information. Upon receiving the handshake request, the cloud selects the corresponding encryption suite, generates a server random number, and sends a response containing the server certificate, the corresponding encryption suite, and the server random number. After verifying the server certificate's validity, the component generates a pre-master secret and encrypts it using the server's public key. The encrypted pre-master secret is then sent to the cloud. The cloud decrypts the pre-master secret using its private key to obtain the plaintext version. Both the installed components and the cloud use the same algorithm, combining the random numbers from both the installed components and the cloud with the pre-master secret, to generate a session key. This session key is then encrypted, and the previous session hash values ​​are mutually verified. Upon successful verification, the handshake process is complete, and a communication channel is established. If the communication channel is successfully established, the handshake communication status is "handshake successful"; if the communication channel fails to be established, the handshake communication status is "handshake failed".

[0040] In one embodiment of this application, an identity verification request is generated, and the identity verification request and the component identity information of each installed component are sent to the cloud, and the identity verification result fed back by the cloud is received. The identity verification request is used to enable the cloud to perform identity verification steps according to the identity verification request.

[0041] In one embodiment of this application, the cloud determines the connectivity status of each installed component based on the handshake communication status, thereby obtaining the component connectivity status. If the handshake communication status is successful, the connectivity status of the installed component is normal; if the handshake communication status is unsuccessful, the connectivity status of the installed component is abnormal.

[0042] In one embodiment of this application, if at least one installed component has an abnormal connection in the component connectivity state, an abnormal transmission instruction is generated and sent to the vehicle transmission device, a connectivity state abnormality pending processing request is generated, and the connectivity state abnormality pending processing request is displayed. The abnormal transmission instruction is used to cause the vehicle transmission device to transmit the vehicle to be detected to the abnormal processing area. The connectivity state abnormality pending processing request includes information on the installed component with the abnormal connection.

[0043] In step S230, if the connectivity status of all components is normal, the control uploads the component identity information of each installed component to the cloud and receives the identity verification result from the cloud.

[0044] In one embodiment of this application, the identity verification result is obtained by the cloud based on the component identity information.

[0045] In one embodiment of this application, an identity verification request is generated, and the identity verification request and the component identity information of each installed component are sent to the cloud. The identity verification result fed back by the cloud is received. The identity verification request is used to enable the cloud to perform identity verification steps according to the identity verification request.

[0046] The identity verification results include the existence verification result of the component, the reuse verification result of the component, the legality verification result of the component data, and the integrity verification result of the component data. The existence verification result of the component is used to represent the existence status of the identity information of each component in the component registration database queried by the cloud. The reuse verification result of the component is used to represent the status of the identity information of each component being used by other vehicles. The legality verification result of the component data is used to represent whether the format of the identity information of each component verified by the cloud conforms to the preset format specification. The integrity verification result of the component data is used to represent the existence status of the key information in the identity information of each component checked by the cloud.

[0047] In one embodiment of this application, after receiving the identity verification result from the cloud, if all component identity information exists, none of the component identity information has been used by other vehicles, the format of each component identity information conforms to the preset format specification, and the key information in each component identity information is complete, then the identity verification result is determined to be error-free; if at least one component identity information is missing, at least one component identity information has been used by other vehicles, at least one component identity information does not conform to the preset format specification, or at least one component identity information is incomplete in terms of key information, then the identity verification result is determined to be abnormal.

[0048] Among them, the existence verification of parts includes querying the existence status of each part's identity information in the cloud-based parts registration database; the reuse verification of parts includes querying the status of each part's identity information being used by other vehicles in the cloud-based system; the legality verification of parts data includes verifying whether the format of each part's identity information conforms to the preset format specifications in the cloud-based system; and the integrity verification of parts data includes checking the existence status of key information in each part's identity information in the cloud-based system.

[0049] In one embodiment of this application, if the identity verification result is abnormal, an abnormal transmission instruction is generated and sent to the vehicle transmission device. An identity verification abnormal pending request is generated based on the identity verification result and displayed. The abnormal transmission instruction is used to cause the vehicle transmission device to transmit the vehicle to be detected to the abnormal processing area.

[0050] In step S240, if the identity verification result is correct, it is determined that the vehicle off-line detection is normal, and the vehicle to be tested is controlled to be taken off the line.

[0051] In one embodiment of this application, before determining that the vehicle off-line inspection is normal, the method further includes controlling the vehicle's infotainment system to connect with the vehicle key via Bluetooth to trigger a seamless positioning detection between the vehicle key and the vehicle's infotainment system; if the seamless positioning detection feedback indicates normal positioning, then the vehicle off-line inspection is determined to be normal, and the vehicle under inspection is controlled to be removed from the production line. Here, "successful positioning detection feedback" means that the vehicle is continuously supporting the seamless positioning function.

[0052] Specifically, the relevant technicians launch the dedicated APP on the client side, load the key resources and configuration files, prepare for Bluetooth connection, select the vehicle to be tested to initiate a Bluetooth connection request, establish a Bluetooth connection with the vehicle to be tested, and after the connection is successful, the APP activates the non-intrusive positioning function, and exchanges data with the Bluetooth module of the vehicle to be tested through the Bluetooth connection to obtain the vehicle's location information and other relevant data, so as to display the vehicle's current location information and other relevant network function status on the APP interface.

[0053] In one embodiment of this application, after the vehicle to be tested is taken off the production line, the process further includes continuing to circulate the vehicle for subsequent functional inspections. These functional inspections are a comprehensive test conducted before the vehicle completes production, designed to verify that all vehicle functions are operating normally and to ensure that the vehicle meets the highest quality standards before delivery to the customer. These inspections include, but are not limited to, electrical system testing, powertrain testing, braking system testing, steering system testing, connectivity function testing, safety system testing, comfort testing, and emissions and environmental protection testing.

[0054] Reference Figure 3 As shown, Figure 3 This is an exemplary embodiment of this application illustrating a specific vehicle off-line detection interaction diagram. For example... Figure 3 As shown in a specific embodiment of this application, the specific interaction process of this method is described as the interaction process between the factory side and the vehicle cloud. It should be noted that the vehicle cloud here has the same meaning as the cloud in the above embodiment, and is not another form of port representation. This interaction process is a flowchart of the overall process interaction including the above-mentioned vehicle off-line inspection method. For details, please refer to [link to relevant documentation]. Figure 3 First, the vehicle assembly process is carried out at the factory. After the connected components are assembled normally, the vehicle undergoes an initial electrical test, which involves writing the equipment information (VIN, equipment certificate, etc.) into the vehicle's infotainment system.

[0055] In one specific embodiment of this application, after the data is written to the vehicle system, communication between the installed components and the vehicle-to-cloud (V2X) is triggered to verify whether the communication of the installed components is normal. The verification result is then fed back to the factory, which determines whether to intercept the vehicle based on the verification result. Vehicles with normal V2X communication proceed to the next stage and report all connected component data, including the Device ID (PDID). The V2X uses the PDID to verify the existence, reuse, legality, and integrity of the component data, and feeds the verification result back to the factory, which then determines whether to intercept the vehicle. If the verification is successful, the client initiates a Bluetooth connection upon startup. After connection, seamless positioning is triggered. On the first use, manual pairing is required. Vehicles that pass the verification proceed to the next stage and are then taken offline for functional checks.

[0056] This invention provides a vehicle off-line inspection method, system, device, and storage medium. It acquires the initial information and identity information of installed components in the vehicle under inspection, writes the initial information into the vehicle's infotainment system, and then controls each installed component to communicate with the cloud to obtain the component connectivity status. If all component connectivity statuses are normal, the component identity information is uploaded to the cloud for identity verification. If the verification result is correct, the vehicle off-line inspection is deemed normal, and the vehicle under inspection is removed from the production line. This method, after writing the initial component information, controls each installed component to communicate with the cloud, verifying the communication capability between the components and the cloud, ensuring the stability and reliability of data transmission. If all components are connected normally, identity verification is performed in the cloud, ensuring the legality of the component identity information and the integrity of the data. This avoids network connectivity anomalies caused by data errors. Through multi-layered detection and verification mechanisms, including a cloud data verification mechanism, the reliability of data transmission is ensured, network connectivity anomalies caused by data errors are avoided, the accuracy and completeness of component information detection are improved, the possibility of human error is reduced, the risk of problematic vehicles leaving the system is lowered, and production quality and user satisfaction are improved. Secondly, when vehicles are subsequently repaired, it can reduce the likelihood of being intercepted at the repair station due to already installed parts.
