[0024] The following will describe the embodiments of the present invention with reference to the accompanying drawings and specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways 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, 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 used to illustrate the basic concept of the present invention in a schematic manner, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0026] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present invention difficult to understand.

[0027] The "and / or" mentioned in this application describes the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0028] First of all, it should be noted that this application is applicable to offline testing of connected components in vehicles, so the installed components mentioned below include components that have been installed in the vehicle to be tested and are used to support the connected functions. In the embodiments of this application, the "line" in the terms "offline" and "return line" refers to the production line and maintenance line.

[0029] Figure 1 It is a schematic diagram of an exemplary system architecture shown in an exemplary embodiment of the present application.

[0030] Reference Figure 1 As shown, the system architecture may include a vehicle to be detected 110, a computer device 120 and a cloud 130. The computer device 120 obtains the initial component information and component identity information of the installed components in the vehicle to be detected 110, and writes the initial component information into the vehicle system; in response to the completion of writing the initial component information into the vehicle 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 uploading the component identity information of each installed component to the cloud 130, and receives the identity verification result fed back by the cloud 130, which is obtained by the cloud performing identity verification based on the component identity information; if the identity verification result is that the verification is correct, it is determined that the vehicle offline inspection is normal, and the computer device 120 controls the vehicle to be detected 110 to be offline. The above-mentioned computer device 120 can be at least one of a microcomputer, an embedded computer, a network computer, an industrial computer, etc., and the computer device is installed with computer software, instructions, scripts or plug-in tools for vehicle offline testing, and is connected to equipment and related testing devices for vehicle offline testing; the above-mentioned vehicle to be tested 110 refers to a vehicle to be offline that has completed vehicle assembly in the production line or a vehicle that is undergoing maintenance and repair in the production line.

[0031] Schematically, the computer device 120 obtains the initial component information and component identity information of the installed components in the vehicle to be tested 110, and writes the initial component information into the vehicle system. After writing, it controls each installed component to communicate with the cloud 130 to obtain the component connectivity status. If the component connectivity status is normal, the component identity information is uploaded to the cloud 130 and identity verification is performed to obtain the identity verification result. If the verification is correct, it is determined that the vehicle offline inspection is normal, and the vehicle to be tested 110 is controlled to be offline. After completing the writing of the initial component information, this method controls each installed component to communicate with the cloud, verifies the communication ability of the component and the cloud, and ensures the stability and reliability of data transmission. If the components are all connected normally, identity verification is performed in the cloud to ensure the legitimacy of the component identity information and the integrity of the data, and avoids abnormal networking functions caused by data errors. Through a multi-layer detection and verification mechanism, a cloud data verification mechanism is introduced to ensure the reliability of data transmission, avoid abnormal networking functions caused by data errors, improve the accuracy and integrity of component information detection, reduce the possibility of human operation errors, reduce the risk of problem vehicles flowing out, and improve production quality and user satisfaction.

[0032] Figure 2 is a flow chart of a vehicle offline detection method shown in an exemplary embodiment of the present application. The vehicle offline detection method can be Figure 1 The implementation environment may be implemented in other implementation environments, and the above implementation environments are not specifically limited here. Figure 2 As shown, the flowchart of the vehicle offline detection method includes at least steps S210 to S240, which are described in detail as follows:

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

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

[0035] If the received re-inspection feedback message indicates that the assembly re-inspection is correct, the step of obtaining the initial component information and component identity information of the installed components in the vehicle to be inspected is performed; if the received re-inspection feedback message indicates that the assembly connection is abnormal, an abnormal transmission instruction is generated and sent to the vehicle transmission device, an assembly abnormality pending request is generated, and the assembly abnormality pending request is displayed. The abnormal transmission instruction is used to enable the vehicle transmission device to transmit the vehicle to be inspected to the abnormal processing area. The above-mentioned initial component information includes but is not limited to the vehicle frame number (VIN), equipment certificate, production date, serial number, and the component identity information includes the networked component device ID (PDID). The abnormal processing area is an area for temporarily storing vehicles that are detected abnormally during the vehicle offline inspection, and vehicles that are detected abnormally can be transported through the production line. After the terminal is displayed, the relevant technical personnel will make processing decisions and re-maintenance based on the displayed cause of the detection abnormality, which greatly reduces the risk of problem vehicles flowing out.

[0036] In one embodiment of the present application, the initial information of the parts is written into the vehicle system by using sensors and scanning devices, such as barcode scanners, RFID readers, etc., wherein an RFID (Radio-Frequency Identification) reader is a device for reading and writing RFID tag information. RFID technology uses radio waves for contactless data transmission and is widely used in logistics, manufacturing and other fields. The initial information of the installed parts in the vehicle to be inspected is obtained, including but not limited to the vehicle frame number (VIN), equipment certificate, production date, serial number, etc., and this information is transmitted to the vehicle system through the vehicle network (such as CAN bus, Ethernet, etc.). After receiving the information, the vehicle system performs data parsing and verification to ensure that the format of the information is correct, complete and accurate, and then stores the verified information in the configuration database to generate corresponding records.

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

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

[0039] In one embodiment of the present application, controlling each installed component to communicate with the cloud and obtaining the component connectivity status includes the vehicle system generating a cloud communication request and sending the cloud communication request to each installed component, each installed component configures a corresponding communication interface according to a preset network configuration information file, and performs handshake communication with the cloud through the corresponding communication interface; wherein the handshake communication includes controlling the component to send a handshake request to the cloud, the handshake request includes a list of encryption suites supported by the client, a random number and other information, after the cloud receives the handshake request, it selects the corresponding encryption suite, generates a random number of the server, and then sends a response including the server certificate, the corresponding encryption suite and the server random number, after the component verifies the legitimacy of the server certificate, it generates a pre-set key (Pre-Master Secret), and encrypts it with the server public key, and then sends the encrypted pre-set key to the cloud, the cloud uses the private key to decrypt the pre-set key, and obtains the plaintext pre-set key, the installed component and the cloud use the same algorithm respectively, combine the random numbers of the installed component and the cloud and the pre-set key, generate a session key, and encrypt it with the generated session key, and perform mutual verification of the previous session hash value, after the verification is passed, the handshake process is completed, and a communication channel is established. If the communication channel is successfully established, the status of the handshake communication is a handshake success. If the communication channel fails to be established, the status of the handshake communication is a handshake failure.

[0040] In one embodiment of the present 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, wherein the identity verification request is used to enable the cloud to perform an identity verification step according to the identity verification request.

[0041] In one embodiment of the present application, the cloud determines the connectivity status of each installed component based on the status of handshake communication to obtain the connectivity status of the component, wherein if the status of handshake communication is a successful handshake, the connectivity status of the installed component is a normal connection, and if the status of handshake communication is a failed handshake, the connectivity status of the installed component is an abnormal connection.

[0042] In one embodiment of the present application, if there is an abnormal connection of at least one installed component in the component connectivity status, an abnormal transmission instruction is generated and sent to the vehicle transmission device, a connectivity status abnormal pending request is generated, and the connectivity status abnormal pending request is displayed. The abnormal transmission instruction is used to enable the vehicle transmission device to transmit the vehicle to be inspected to the abnormal processing area, and the connectivity status abnormal pending request includes information about the installed components with abnormal connection.

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

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

[0045] In one embodiment of the present 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.

[0046] Among them, the identity verification results include the parts existence verification results, the parts reuse verification results, the parts data legality verification results and the parts data integrity verification results. The parts existence verification results are used to represent the existence status of each part identity information in the cloud query parts registration database. The parts reuse verification results are used to represent the status of each part identity information in the cloud query being used by other vehicles. The parts data legality verification results are used to represent whether the format of each part identity information verified by the cloud complies with the preset format specifications. The parts data integrity verification results are used to represent the existence status of key information in each part identity information checked by the cloud.

[0047] In one embodiment of the present application, after receiving the identity verification result fed back by the cloud, if the identity information of each component exists, the identity information of each component is not used by other vehicles, the format of the identity information of each component complies with the preset format specification and the key information in the identity information of each component is complete, then the identity verification result is determined to be correct; if at least one component identity information does not exist, at least one component identity information is used by other vehicles, the format of at least one component identity information does not comply with the preset format specification or the key information in at least one component identity information is incomplete, then the identity verification result is determined to be abnormal.

[0048] Among them, the parts existence verification includes cloud query on the existence status of each parts identity information in the parts registration database; the parts reuse verification includes cloud query on the status of each parts identity information being used by other vehicles; the parts data legality verification includes cloud verification on whether the format of each parts identity information complies with the preset format specification; the parts data integrity verification includes cloud check on the existence status of key information in each parts identity information.

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

[0050] In step S240, if the identity verification result is that the verification is correct, it is determined that the vehicle offline inspection is normal, and the vehicle to be inspected is controlled to be offline.

[0051] In one embodiment of the present application, before determining that the vehicle offline detection is normal, it also includes controlling the vehicle system of the vehicle to be detected to connect to the vehicle key through Bluetooth to trigger the non-contact positioning detection between the vehicle key and the vehicle system of the vehicle to be detected; if the non-contact positioning detection feedback is normal, it is determined that the vehicle offline detection is normal, and the vehicle to be detected is controlled to be offline. Among them, the non-contact positioning detection feedback is normal means that the vehicle is normally supporting the continuous non-contact positioning function.

[0052] Specifically, the relevant technicians start the client's dedicated APP, load key resources and configuration files, prepare for Bluetooth connection, select the vehicle to be detected to initiate a Bluetooth connection request, and establish a Bluetooth connection with the vehicle to be detected. After the connection is successful, the APP starts the contactless positioning function, and exchanges data with the Bluetooth module of the vehicle to be detected through the Bluetooth connection to obtain the vehicle's location information and other related data, so as to display the vehicle's current location information and other related network function status on the APP interface.

[0053] In one embodiment of the present application, after the vehicle to be tested is controlled to be off the assembly line, it also includes continuing to circulate the off-assembly vehicle and conducting subsequent functional inspections. Among them, the functional inspection is a comprehensive inspection conducted before the vehicle is completed, which aims to verify whether the various functions of the vehicle are operating normally and ensure that the vehicle meets the highest quality standards before being delivered to customers, including but not limited to electrical system inspection, power system inspection, brake system inspection, steering system inspection, network function inspection, safety system inspection, comfort inspection, and emission and environmental protection inspection.

[0054] Reference Figure 3 As shown, Figure 3 FIG. 1 is a specific vehicle offline detection interaction diagram shown in an exemplary embodiment of the present application. Figure 3 As shown, in a specific embodiment of the present application, the specific interaction process of the method is expressed as the interaction process between the factory end 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 a port representation in other forms. This interaction process is an overall process interaction diagram including the above vehicle offline detection method. For details, see Figure 3 First, the vehicle assembly process is carried out at the factory. After the vehicle is normally assembled with connected components, an initialization electrical inspection is performed. The initialization electrical inspection is to write the equipment information (frame number, equipment certificate, etc.) into the vehicle system.

[0055] In a specific embodiment of the present application, after writing to the vehicle system, the installed parts and the vehicle-to-cloud communication are triggered to verify whether the communication of the installed parts is normal, and the verification results are fed back to the factory side, and the factory side confirms whether to intercept based on the verification results, so as to handle the abnormality or return the vehicle to be detected after the interception. Vehicles with normal vehicle-to-cloud communication flow down and report all networked parts data, including device ID (PDID). The vehicle-to-cloud performs part existence verification, part reuse verification, part data legality verification and part data integrity verification through PDID, and feeds back the verification results to the factory side, and the factory side confirms whether to intercept based on the verification results. When the verification is correct, the client actively initiates a Bluetooth connection after startup, and starts to trigger the non-sensing positioning after the connection is completed. Among them, manual triggering is required to complete the pairing when used for the first time. Vehicles that pass the verification results flow down and go offline normally for functional inspection.

[0056] The present invention provides a vehicle offline detection method, system, device and storage medium. The method obtains the initial component information and component identity information of the components installed in the vehicle to be detected, writes the initial component information into the vehicle computer system, and after writing, controls each installed component to communicate with the cloud to obtain the component connection status. If the component connection status is normal, the component identity information is uploaded to the cloud and identity verification is performed to obtain the identity verification result. If the verification is correct, it is determined that the vehicle offline detection is normal, and the vehicle to be detected is controlled to be offline. After completing the writing of the initial component information, the method controls each installed component to communicate with the cloud, verifies the communication ability of the component and the cloud, ensures the stability and reliability of data transmission, and if the components are all connected normally, identity verification is performed in the cloud to ensure the legitimacy of the component identity information and the integrity of the data, avoids the abnormality of the network connection function caused by data errors, and introduces a cloud data verification mechanism through a multi-layer detection and verification mechanism to ensure the reliability of data transmission, avoids the abnormality of the network connection function caused by data errors, improves the accuracy and integrity of component information detection, reduces the possibility of human operation errors, reduces the risk of problem vehicles flowing out, and improves production quality and user satisfaction. Secondly, when subsequent vehicles are returned for repair, it can reduce the direct interception of installed parts at the repair site.
