[0032] In some embodiments, optionally, Figure 1 As shown, a vehicle fault detection method is proposed, comprising:

[0033] Step S101, acquiring data in the manufacturing system to obtain basic vehicle data.

[0034] In this embodiment, the vehicle fault detection method is executed by a cloud diagnostic system, which is a cloud system capable of detecting vehicle faults, wherein the cloud diagnostic system is respectively connected and communicated with the vehicle's corresponding production and manufacturing system, dealer management system and Internet of Vehicles service system.

[0035] It should be noted that the production and manufacturing system is a system that manages vehicle parts information, including specific information of vehicles off the production line. The dealer management system is a system that manages vehicle maintenance data and maintenance cases of dealer stores. The Internet of Vehicles service system is a system that manages vehicle status, replacement parts information, remote wake-up and other functions.

[0036] The cloud diagnosis system communicates with the production and manufacturing system, reads the data in the production and manufacturing system, and obtains the basic data of the vehicle, wherein the basic data is the basic data of the vehicle.

[0037] Exemplarily, the basic data may include the series and model of the vehicle, and the relationship data between the vehicle and the parts under the model.

[0038] Step S102, acquiring data from the dealer management system to obtain maintenance data corresponding to the vehicle.

[0039] The cloud diagnosis system communicates with the dealer management system, reads the data in the dealer management system, and obtains the vehicle maintenance data, wherein the maintenance data is the vehicle maintenance record data.

[0040] For example, the maintenance data may include data such as a vehicle maintenance log and a vehicle maintenance processing flow.

[0041] Step S103, acquiring data from the Internet of Vehicles service system to obtain vehicle parts replacement information.

[0042] The cloud diagnosis system communicates with the Internet of Vehicles service system, reads data in the Internet of Vehicles service system, and obtains the vehicle's parts replacement information, wherein the parts replacement information indicates the replacement status of parts in the vehicle.

[0043] For example, the parts replacement information may include a replacement record of the vehicle.

[0044] Step S104, determining the vehicle's fault information based on the basic data, maintenance data and parts replacement information.

[0045] The cloud-based diagnostic system processes basic data, maintenance data, and parts replacement information to obtain vehicle fault information, which indicates the vehicle's fault condition.

[0046] The fault information may include the cause of the fault and the faulty component of the vehicle.

[0047] Exemplarily, the cloud-based diagnostic system obtains a fault identification model, inputs basic data, maintenance data, and parts replacement information into the fault identification model, and obtains vehicle fault information.

[0048] Step S105, sending the fault information to the vehicle.

[0049] The cloud diagnostic system sends fault information to the vehicle.

[0050] Exemplarily, the cloud diagnostic system can send fault information to the vehicle user's terminal.

[0051] It should be noted that the cloud-based diagnostic system obtains data from the production and manufacturing system, dealer management system and Internet of Vehicles service system respectively, and can determine the vehicle's fault information based on the vehicle's basic data, maintenance data and parts replacement information. Since the cloud-based diagnostic system covers multiple aspects of data such as the vehicle's basic data, maintenance data and parts replacement information, it improves the accuracy of fault information, that is, improves the accuracy of detecting vehicle faults.

[0052] In the vehicle fault detection method of this embodiment, the cloud-based diagnostic system obtains data from the production and manufacturing system, the dealer management system, and the Internet of Vehicles service system respectively, and can determine the vehicle's fault information based on the basic data, maintenance data, and parts replacement information. Since the cloud-based diagnostic system covers multiple aspects of the vehicle, such as basic data, maintenance data, and parts replacement information, the accuracy of the fault information is guaranteed, thereby improving the accuracy of vehicle fault detection.

[0053] In some embodiments, optionally, a vehicle fault detection method is proposed. After acquiring data in a production and manufacturing system corresponding to the vehicle and obtaining basic data of the vehicle, the method further includes:

[0054] Step S201, performing data detection on basic data to obtain detection results of the basic data.

[0055] In this embodiment, the cloud-based diagnostic system performs data detection on the basic data to obtain a detection result of the basic data, and the detection result can indicate the data accuracy of the basic data.

[0056] Exemplarily, the cloud-based diagnostic system detects the legitimacy and integrity of the basic data and can obtain the detection result of the basic data, that is, the detection result can indicate the legitimacy and integrity of the basic data.

[0057] Step S202: when the detection result shows that the data is illegal, the basic data of the vehicle is re-acquired.

[0058] When the test result shows that the data is illegal, it means that the basic data cannot be used and the cloud diagnosis system needs to obtain the basic data again.

[0059] For example, when the test result shows that the data is legal, it means that the basic data can be used, and the cloud-based diagnostic system does not need to reacquire the basic data.

[0060] For example, when the detection result is that the data is illegal, it means that the basic data may be incomplete and therefore cannot be used.

[0061] In the vehicle fault detection method of this embodiment, the cloud diagnostic system determines the legitimacy of the basic data based on the detection results of the basic data, thereby ensuring the data accuracy of the basic data and further ensuring the data accuracy of the fault information.

[0062] In some embodiments, optionally, a vehicle fault detection method is proposed to obtain data in a dealer management system to obtain maintenance data corresponding to the vehicle, including:

[0063] Step S301, obtaining a preset fault code.

[0064] In this embodiment, the dealer management system stores a plurality of historical cases, and the maintenance data includes maintenance cases, wherein the historical cases are historical fault handling cases of the vehicle, and the maintenance cases are maintenance cases corresponding to the vehicle.

[0065] For example, the historical cases may include historical maintenance cases of various faults of the vehicle.

[0066] The cloud diagnostic system obtains a preset fault code, where the fault code is a number corresponding to the vehicle fault.

[0067] Exemplarily, the fault code for a vehicle engine fault may be fault 1.

[0068] Step S302: Determine a maintenance case from multiple historical cases according to the fault code.

[0069] The cloud-based diagnostic system screens data from multiple historical cases to obtain maintenance cases corresponding to the fault codes.

[0070] Exemplarily, the maintenance case may be a maintenance case corresponding to an engine failure.

[0071] In the vehicle fault detection method of this embodiment, the cloud diagnostic system screens data from multiple historical cases to determine the maintenance case corresponding to the fault code, thereby ensuring the data accuracy of the maintenance case, and then determining the vehicle's fault information, thereby ensuring the accuracy of vehicle fault detection.

[0072] In some embodiments, optionally, a vehicle fault detection method is proposed to obtain data in a vehicle networking service system to obtain vehicle parts replacement information, including:

[0073] Step S401, obtaining the running status of the vehicle.

[0074] In this embodiment, the cloud diagnostic system can determine the operating status of the vehicle through the Internet of Vehicles service system, wherein the operating status represents the operating status of the vehicle.

[0075] Exemplarily, the operating state may be a wake-up state or a sleep state.

[0076] Step S402: when the running state is the awake state, determine the authorization result of the vehicle by the Internet of Vehicles service system.

[0077] When the running state is the awake state, the cloud diagnostic system determines the authorization result of the connected vehicle service system to the vehicle through the connected vehicle service system, wherein the authorization result indicates the access rights of the connected vehicle service system to the vehicle.

[0078] Exemplarily, the authorization result may be authorized or not authorized.

[0079] Exemplarily, when the Internet of Vehicles service system has not authorized the vehicle, the Internet of Vehicles service system is required to authorize the vehicle.

[0080] Step S403: When the authorization result is authorized, obtain the parts replacement information in the Internet of Vehicles service system.

[0081] When the authorization result is authorized, it means that the data in the Internet of Vehicles service system can be read, and the cloud diagnostic system obtains the parts replacement information in the Internet of Vehicles service system.

[0082] For example, when the authorization result is unauthorized, the cloud diagnostic system cannot obtain the parts replacement information in the Internet of Vehicles service system, and the vehicle needs to be authorized through the Internet of Vehicles service system.

[0083] In the vehicle fault detection method of this embodiment, when the authorization result is authorized, the cloud diagnostic system obtains the parts replacement information in the Internet of Vehicles service system, thereby ensuring the information security of the parts replacement information and further ensuring the system security of the cloud diagnostic system.

[0084] In some embodiments, optionally, a vehicle fault detection method is proposed. After obtaining the running state of the vehicle, the method further includes:

[0085] Step S501, when the running state is a dormant state, waking up the vehicle through the Internet of Vehicles service system.

[0086] In this embodiment, when the vehicle is in a dormant state, the cloud diagnostic system wakes up the vehicle through the Internet of Vehicles service system.

[0087] For example, the cloud diagnostic system can remind the vehicle user to wake up the vehicle through the Internet of Vehicles service system.

[0088] In the vehicle fault detection method of this embodiment, when the vehicle is in a dormant state, the cloud diagnostic system wakes up the vehicle through the Internet of Vehicles service system, ensuring that the cloud diagnostic system can read the vehicle's parts replacement information, thereby ensuring the accuracy of vehicle fault detection.

[0089] In some embodiments, optionally, a vehicle fault detection method is proposed. After determining the authorization result of the vehicle by the Internet of Vehicles service system, the method further includes:

[0090] Step S601, when the authorization result is unauthorized, the authorization result is changed through the Internet of Vehicles service system.

[0091] In this embodiment, when the authorization result is unauthorized, the cloud diagnostic system changes the authorization result through the Internet of Vehicles service system.

[0092] Exemplarily, when the authorization result is unauthorized, the cloud diagnostic system transforms the authorization result through the Internet of Vehicles service system so that the authorization result is authorized.

[0093] In the vehicle fault detection method of this embodiment, when the authorization result is unauthorized, the cloud diagnosis system changes the authorization result through the Internet of Vehicles service system to ensure that the cloud diagnosis system can read the vehicle parts replacement information and ensure the data accuracy of the vehicle fault information.

[0094] In some embodiments, optionally, a vehicle fault detection method is proposed. After determining the fault information of the vehicle according to the basic data, the maintenance data and the parts replacement information, the method further:

[0095] Step S701, acquiring data from the certificate management system to obtain the vehicle's verification certificate.

[0096] In this embodiment, the cloud diagnostic system communicates with the certificate management system, reads data in the certificate management system, and obtains the vehicle's verification certificate, wherein the verification certificate is used to encrypt vehicle data.

[0097] Exemplarily, the verification certificate may be a key authentication certificate.

[0098] Step S702: encrypt the fault information based on the verification certificate to obtain encrypted fault information.

[0099] The cloud diagnosis system encrypts the fault information based on the verification certificate to obtain the encrypted fault information.

[0100] Exemplarily, the system design of the certificate management system includes cloud demand design and vehicle demand design. Because the cloud diagnostic server and other subsystems are deployed on the private cloud, the communication between them is secure. The cloud diagnostic server's communication with the outside world is limited to vehicle-side communication, and two-way authentication based on certificates will be used.

[0101] The requirements and solutions for the vehicle-side certificate management system include:

[0102] The in-vehicle infotainment system needs to integrate the certificate application application. When the in-vehicle infotainment system writes the vehicle identification code, it is necessary to start the certificate management system certificate application process and obtain the in-vehicle infotainment system private certificate from the server of the certificate management system.

[0103] (1) Authentication: The vehicle needs to use a certificate management system to verify its identity to ensure that only authorized vehicles can communicate with the cloud. Digital certificates can be used to authenticate the vehicle.

[0104] (2) Communication encryption: Use the certificate management system to provide the vehicle with the ability to encrypt communication, ensuring that the data transmitted between the vehicle and the cloud is secure. Communication can be encrypted through the protocol.

[0105] (3) Key management: The certificate management system needs to provide an effective key management mechanism to ensure that the generation, distribution and update of keys are secure and reliable.

[0106] (4) Certificate update: Provide a certificate update mechanism for the vehicle side to ensure the validity of the certificate and handle certificate updates in a timely manner to prevent expiration and other problems.

[0107] The requirements and solutions for cloud certificate management system include:

[0108] (1) Vehicle identity authentication: The cloud needs to use a certificate management system to verify the identity of the vehicle to ensure that only legitimate vehicles can access cloud services.

[0109] (2) Data integrity: Use technologies such as digital signatures to ensure the integrity of data received from the vehicle and prevent data tampering.

[0110] (3) Access control: Establish an effective access control strategy based on the certificate management system to ensure that only authorized vehicles can access specific cloud services and data.

[0111] (4) Key management: Ensure that the cloud has a secure key management system for generating, distributing, and rotating keys to maintain the security of communications.

[0112] The data connection solution includes:

[0113] (1) Bidirectional authentication: Bidirectional authentication ensures that both the vehicle and the cloud can verify each other’s identity and establish a trusted communication channel.

[0114] (2) Encrypted communication: Use security protocols to establish encrypted communication channels to protect the confidentiality of data.

[0115] (3) Security protocol: Use secure communication protocols to ensure the security of data transmission.

[0116] (4) Data signature: Digitally sign the transmitted data to ensure data integrity and source credibility.

[0117] (5) Exception handling: Design an exception handling mechanism to handle problems that may arise during communication, such as certificate expiration, authentication failure, etc.

[0118] (6) Logging: Record detailed log information to facilitate auditing and investigation when security incidents occur.

[0119] In the vehicle fault detection method of this embodiment, the cloud diagnostic system encrypts the fault information based on the verification certificate to obtain the encrypted fault information, thereby ensuring the information security of the vehicle fault information and further ensuring the system security of the cloud diagnostic system.

[0120] like Figure 2 As shown, in an embodiment of the present application, a vehicle fault detection device 800 is provided, which is applied to a cloud diagnosis system, and data communication between a manufacturing system, a dealer management system, and an Internet of Vehicles service system corresponding to the vehicle and a vehicle diagnosis system is established respectively. The vehicle fault detection device 800 includes:

[0121] An acquisition unit 802 is used to acquire data in the manufacturing system to obtain basic data of the vehicle;

[0122] The acquisition unit 802 is also used to acquire data from the dealer management system to obtain maintenance data corresponding to the vehicle;

[0123] The acquisition unit 802 is further used to acquire data in the vehicle networking service system to obtain vehicle parts replacement information;

[0124] The processing unit 804 is used to determine the fault information of the vehicle according to the basic data, the maintenance data and the parts replacement information;

[0125] The sending unit 806 is used to send the fault information to the vehicle.

[0126] In this embodiment, the vehicle fault detection method is executed by a cloud diagnostic system, which is a cloud system capable of detecting vehicle faults, wherein the cloud diagnostic system is respectively connected and communicated with the vehicle's corresponding production and manufacturing system, dealer management system and Internet of Vehicles service system.

[0127] It should be noted that the production and manufacturing system is a system that manages vehicle parts information, including specific information of vehicles off the production line. The dealer management system is a system that manages vehicle maintenance data and maintenance cases of dealer stores. The Internet of Vehicles service system is a system that manages vehicle status, replacement parts information, remote wake-up and other functions.

[0128] The cloud diagnosis system communicates with the production and manufacturing system, reads the data in the production and manufacturing system, and obtains the basic data of the vehicle, wherein the basic data is the basic data of the vehicle.

[0129] Exemplarily, the basic data may include the series and model of the vehicle, and the relationship data between the vehicle and the parts under the model.

[0130] The cloud diagnosis system communicates with the dealer management system, reads the data in the dealer management system, and obtains the vehicle maintenance data, wherein the maintenance data is the vehicle maintenance record data.

[0131] For example, the maintenance data may include data such as a vehicle maintenance log and a vehicle maintenance processing flow.

[0132] The cloud diagnosis system communicates with the Internet of Vehicles service system, reads data in the Internet of Vehicles service system, and obtains the vehicle's parts replacement information, wherein the parts replacement information indicates the replacement status of parts in the vehicle.

[0133] For example, the parts replacement information may include a replacement record of the vehicle.

[0134] The cloud-based diagnostic system processes basic data, maintenance data, and parts replacement information to obtain vehicle fault information, which indicates the vehicle's fault condition.

[0135] The fault information may include the cause of the fault and the faulty component of the vehicle.

[0136] Exemplarily, the cloud-based diagnostic system obtains a fault identification model, inputs basic data, maintenance data, and parts replacement information into the fault identification model, and obtains vehicle fault information.

[0137] The cloud diagnostic system sends fault information to the vehicle.

[0138] Exemplarily, the cloud diagnostic system can send fault information to the vehicle user's terminal.

[0139] It should be noted that the cloud-based diagnostic system obtains data from the production and manufacturing system, dealer management system and Internet of Vehicles service system respectively, and can determine the vehicle's fault information based on the vehicle's basic data, maintenance data and parts replacement information. Since the cloud-based diagnostic system covers multiple aspects of data such as the vehicle's basic data, maintenance data and parts replacement information, it improves the accuracy of fault information, that is, improves the accuracy of detecting vehicle faults.

[0140] For example, Figure 3 As shown in the figure, the manufacturing system manages vehicle model parts information, including specific information of vehicles off the production line. The cloud diagnosis platform mainly obtains the relationship data of vehicle series, models, vehicles and parts under the model from the manufacturing system. It is used for basic data management of the cloud diagnosis system.

[0141] The dealer management system manages the dealer's vehicle maintenance data, maintenance cases, etc. The cloud diagnosis platform mainly obtains maintenance case links from the dealer management system, performs maintenance case query and association of fault codes, and is used for data management of the cloud diagnosis system fault case library.

[0142] The certificate management system manages the issuance and signature verification of vehicle-side certificates. The cloud diagnostic platform mainly calls the interface from the certificate management system to sign and encrypt diagnostic data for secure communication between the cloud diagnostic system and the vehicle.

[0143] The Internet of Vehicles service system manages the vehicle status, parts replacement information, remote wake-up and other functions. The cloud diagnosis platform mainly obtains the vehicle status from the Internet of Vehicles service system call interface. If the vehicle is in a dormant state, it can remotely wake up the vehicle according to the situation, obtain the replacement record of the specific vehicle, and the authorization function of remote diagnosis push to the owner's mobile phone.

[0144] The in-vehicle infotainment system is an in-vehicle comprehensive information processing system that uses a dedicated in-vehicle central processor, based on the body bus system and Internet services. The in-vehicle infotainment system can realize a series of applications including three-dimensional navigation, real-time traffic conditions, network TV, assisted driving, fault detection, vehicle information, body control, mobile office, wireless communication, online entertainment functions, etc.

[0145] For example, Figure 4As shown, the cloud diagnostic system connects to the technology center through the business middle platform. The business middle platform provides a unified data interface, and the data of different production and manufacturing systems are distinguished by business unit codes. The scope of data obtained from the production and manufacturing system through the business middle platform is as follows: obtain all vehicle series information, including brand information, etc.; obtain all vehicle model information; obtain vehicle list; obtain electronic control unit information under the vehicle model (including part type information). Among them, the cloud diagnostic system only obtains data from the production and manufacturing system and does not push data to the production and manufacturing system.

[0146] For example, Figure 5 As shown, the data currently obtained from the dealer management system includes: obtaining a list of repair cases for fault codes of related vehicles; obtaining a repair case code and repair case details.

[0147] Exemplarily, the services of the cloud diagnostic system connected to the Internet of Vehicles service system include: obtaining the status of the relevant vehicle (sleeping or online); calling the interface to realize remote wake-up of the vehicle; calling the interface to realize mobile phone application authorization of the vehicle; and the parts replacement information interface.

[0148] like Figure 6 As shown, the cloud diagnostic system queries the current status of the vehicle through the interface provided by the Internet of Vehicles service system, distinguishes whether the vehicle is online or dormant, and if it is dormant, wakes up the vehicle as needed.

[0149] like Figure 7 As shown, the cloud diagnosis system pushes the remote diagnosis task information to the car owner's mobile phone through the interface provided by the Internet of Vehicles service system, and asks the car owner for authorization permission. Only after authorization permission can the vehicle be remotely diagnosed.

[0150] like Figure 8 As shown, before remote diagnosis, if the cloud diagnosis system involves the replacement of some vehicle parts, such as components of the vehicle infotainment system, it will affect the normal execution of the remote diagnosis function. Therefore, the cloud diagnosis platform needs to understand the replacement status of vehicle parts, and mainly obtains the replacement records of vehicle parts through the interface provided by the Internet of Vehicles service system.

[0151] The vehicle fault detection device 800 in this embodiment and the cloud diagnostic system respectively obtain data from the production and manufacturing system, the dealer management system and the Internet of Vehicles service system, and can determine the vehicle fault information based on the basic data, maintenance data and parts replacement information, thereby ensuring the accuracy of the fault information and improving the accuracy of vehicle fault detection.

[0162] In some embodiments, optionally, a vehicle fault detection device 800 is provided, further comprising:

[0165] The processing unit 804 is further configured to, when the authorization result is unauthorized, change the authorization result through the Internet of Vehicles service system.

[0167] The processing unit 804 is further used to obtain data in the certificate management system to obtain the verification certificate of the vehicle;

[0168] The processing unit 804 is further configured to encrypt the fault information based on the verification certificate to obtain the encrypted fault information.

[0169] In some embodiments, optionally, Fig. 9As shown, a vehicle fault detection device 900 is proposed, and the vehicle fault detection device 900 includes a processor 902 and a memory 904. The memory 904 stores a computer program, and when the computer program is executed by the processor 902, the steps of the vehicle fault detection method in any of the above embodiments are implemented. Therefore, the vehicle fault detection device 900 has all the beneficial effects of the vehicle fault detection method in any of the above embodiments, which will not be repeated here.
