[0028] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0029] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0030] In the related art, when the anti-theft device of a vehicle is damaged, the owner is required to provide a valid anti-theft key during the after-sales replacement of related parts for anti-theft matching of the replacement parts. The anti-theft key is given to the owner for safekeeping when the vehicle is sold, and the anti-theft key owned by the owner is the key to open the anti-theft matching.

[0031] In addition to being kept by the car owner, the anti-theft key can also be stored in the OEM's computer room. If the car owner loses the anti-theft key, the after-sales staff can get the anti-theft key from the OEM's computer room, but it is difficult to obtain the anti-theft key without cloud-based backend data support. Therefore, the only way to flash the vehicle's anti-theft device is to use the factory mode of the after-sales diagnostic equipment. The factory mode only supports anti-theft flashing of new parts that have not been flashed, and the entire set of anti-theft devices of the vehicle needs to be replaced, resulting in excessively high after-sales maintenance costs for the car owner, and it takes too long, reducing the convenience of the car owner's car use.

[0032] The after-sales diagnostic equipment used in the after-sales process supports read permissions and write permissions. There is a situation where the anti-theft key is maliciously read. By replicating the anti-theft key, it is easy to lead to vehicle theft, which poses certain vehicle safety risks and increases the risk of vehicle theft.

[0033] Based on this, a key updating method, device, after-sales diagnostic equipment and medium are provided in the embodiments of the present application. The anti-theft key, the owner's identity information and the vehicle information are bound to verify the owner's identity information, the anti-theft key is obtained from the cloud server, and the cloud server sends the anti-theft key, and then the anti-theft key is written into the replacement parts. In the event that the owner loses the anti-theft key, there is no need to replace all the parts of the anti-theft device. In addition, there is no other module to read the anti-theft key, so that the anti-theft key can be protected, thereby improving the safety of the vehicle.

[0034] Next, the application scenario or system architecture of the embodiment of the present application will be described. Figure 1 As shown, Figure 1 The schematic diagram of the system architecture of key update is shown. The system architecture of key update includes cloud server, offline equipment, after-sales diagnostic equipment, vehicle-side diagnostic port, gateway, anti-theft controller, engine controller and vehicle controller.

[0035] The cloud server is used to store identity keys and anti-theft keys.

[0036] Offline equipment is used for final testing and verification on the vehicle production line to ensure that the produced vehicles meet quality standards, specifications and safety requirements. Offline equipment can connect to the vehicle when it is offline, generate identity keys and anti-theft keys, and save the identity keys and anti-theft keys in the cloud server and various anti-theft components of the vehicle.

[0037] After-sales diagnostic equipment is a special device used for diagnosing, troubleshooting and repairing vehicles. After-sales diagnostic equipment is equipped with a security password, which can be used to start the anti-theft key update process in the after-sales diagnostic equipment. Entering the security password and identity key into the after-sales diagnostic equipment can obtain the corresponding anti-theft key from the cloud server.

[0038] The vehicle-side diagnostic port refers to the interface on the vehicle used to connect to the diagnostic equipment. It is usually located inside the vehicle cockpit. The most common vehicle-side diagnostic port is the OBD (On-Board Diagnostics) interface. By connecting the vehicle-side diagnostic port to the diagnostic equipment, you can perform operations such as diagnosis, reading fault codes, and detecting sensor data.

[0039] The gateway connects the vehicle-side diagnostic port with the anti-theft controller, engine controller and vehicle controller, and can transmit data between different devices.

[0040] The vehicle's anti-theft components include an anti-theft controller, an engine controller and a vehicle controller. Each anti-theft component stores a corresponding anti-theft key, and they can work together to provide vehicle security and anti-theft functions.

[0041] The anti-theft controller is one of the core components of the vehicle anti-theft system, responsible for monitoring and controlling the anti-theft function of the vehicle. The anti-theft controller can communicate with other vehicle systems (such as door locks, sirens, remote controls, etc.) to provide protection and safety mechanisms for the vehicle.

[0042] The engine controller can implement start restriction measures to prevent unauthorized starting and use of the vehicle.

[0043] The vehicle controller is the central control unit of the vehicle. The vehicle controller can also integrate some anti-theft functions, such as vehicle start control, alarm system, vehicle remote positioning, etc.

[0044] Figure 2 It is a schematic flowchart of a key updating method provided in an embodiment of the present application.

[0045] For example, Figure 2 As shown, the key updating method includes:

[0046] Step S101, determining an identity key so as to obtain an anti-theft key suitable for the replacement component from a cloud server according to the identity key.

[0047] If the anti-theft device of the vehicle is damaged, the user can replace the relevant parts through after-sales service. After completing the replacement of parts, the after-sales diagnostic equipment is connected to the vehicle. The user needs to input the identity key into the after-sales diagnostic equipment. The identity key is used to represent the identity of the vehicle owner. The identity of the user can be verified through the identity key.

[0048] After the identity key is determined, the identity key is transmitted to the cloud server through a secure communication channel. For example, the security of the identity key during transmission can be protected by an encrypted communication protocol (such as HTTP protocol) and other security mechanisms. After the identity key is transmitted to the cloud server, an anti-theft key suitable for the replacement part can be obtained from the cloud server according to the identity key.

[0049] In this embodiment, when the vehicle owner is unable to provide the anti-theft key, the corresponding anti-theft key can be obtained from the cloud server by providing the identity key, thereby eliminating the need to replace all anti-theft components of the vehicle.

[0050] Figure 3 This is a schematic flowchart of another key updating method provided in an embodiment of the present application.

[0051] Step S201, obtaining the identity information of the vehicle owner, and sending the identity information of the vehicle owner to the cloud server so that the cloud server can verify the identity of the vehicle owner.

[0052] Step S202, receiving the anti-theft key issued by the cloud server after the vehicle owner's identity is authenticated.

[0053] Here, the car owner's identity information may be the car owner's ID number, mobile phone number, vehicle identification code, etc. The car owner inputs the car owner's identity information into the after-sales diagnostic equipment, thereby being able to obtain the car owner's identity information.

[0054] It is understandable that in the process of purchasing a vehicle, the owner's identity information will be registered. For example, the owner's ID number, mobile phone number, address and other information are recorded in the car purchase order, so that the cloud server can store the owner's identity information and verify the owner's identity through the owner's identity information. In actual applications, the vehicle identification code is used to identify and distinguish each motor vehicle, and the vehicle identification code is regarded as sensitive information. Except for the owner, other users usually cannot directly obtain the vehicle identification code. Based on this, the vehicle identification code can also be used as a credential for verifying the owner's identity.

[0055] After obtaining the owner's identity information, the owner's identity information is sent to the cloud server so that the cloud server can verify the owner's identity. In actual applications, the cloud server will verify the validity and legality of the owner's identity information, determine whether the sent owner's identity information is legal and valid information, and prevent the cloud server from leaking the anti-theft key. After confirming the validity and legality of the owner's identity information, the owner's identity information is verified again to further verify the owner's identity. For example, the owner's identity information can be compared with all the owner's identity information stored in the cloud server. When the owner's identity information is stored in the cloud server, the owner's identity authentication is passed; when the owner's identity information does not exist in the cloud server, the owner's identity authentication fails.

[0056] After the owner's identity is verified, it can be determined that the vehicle is not at risk of being stolen and has the authority to obtain the anti-theft key. At this time, the cloud server can obtain the corresponding anti-theft key based on the owner's identity information and send the anti-theft key, so that the after-sales diagnostic equipment can receive the anti-theft key sent by the cloud server.

[0057] It is understandable that anti-theft parts will be equipped with specific anti-theft keys to ensure that only the anti-theft parts match the corresponding anti-theft parts, thereby improving the overall safety and anti-theft capabilities of the vehicle. Based on this, the anti-theft keys stored in the cloud server are associated with the identity information of the vehicle owner, and the anti-theft keys corresponding to the identity information of the vehicle owner can be provided, thereby avoiding providing the anti-theft keys of anti-theft parts of other vehicles.

[0058] It is understandable that in the case where the same car owner owns multiple vehicles, the owner's identity information can be further represented as the owner's identity of the target vehicle, and the anti-theft key stored in the cloud server can be further associated with the vehicle information, so that the anti-theft key that is compatible with the replacement parts of the target vehicle can be extracted from the cloud server based on the owner's identity information.

[0059] In this embodiment, the cloud server stores different anti-theft keys. When the car owner loses the relevant anti-theft key, the corresponding anti-theft key can be obtained from the cloud server through the car owner's identity information, so that the anti-theft key can be flashed to the replacement parts, without having to replace all anti-theft parts and then reconfigure the corresponding anti-theft key.

[0060] Figure 4 This is a schematic flowchart of another key updating method provided in an embodiment of the present application.

[0061] Step S301, obtain the identity key provided by the car owner, and send the identity key to the cloud server.

[0062] Step S302, receiving the anti-theft key issued by the cloud server based on the identity key.

[0063] Here, the identity key is confidential information used to verify the identity of the car owner, which can be a password, code, digital sequence or other forms of confidential data. In practical applications, the identity key can be stored in a confidential envelope and handed over to the car owner for safekeeping. When the car owner replaces parts, he needs to provide the identity key in the confidential envelope. The identity key provided by the car owner is obtained and input into the after-sales diagnostic device, so that the identity key can be sent to the cloud server. The cloud server can send the corresponding anti-theft key to the after-sales diagnostic device based on the identity key.

[0064] It is understandable that anti-theft parts will be equipped with specific anti-theft keys to ensure that only the anti-theft parts match the corresponding anti-theft parts, thereby improving the overall safety and anti-theft capabilities of the vehicle. Based on this, the anti-theft keys stored in the cloud server are associated with the identity keys, and the identity keys can be provided to obtain the corresponding anti-theft keys, thereby avoiding providing the anti-theft keys of anti-theft parts of other vehicles.

[0065] In actual applications, the cloud server will verify the identity key. First, the cloud server will verify the validity and legality of the identity key to determine whether the identity key sent is legal and valid information to prevent the cloud server from leaking the anti-theft key. After confirming the validity and legality of the identity key, the identity key is verified again to determine the identity of the car owner. For example, the identity key can be compared with all identity keys stored in the cloud server. When the identity key is stored in the cloud server, the car owner's identity authentication is passed; when the identity key does not exist in the cloud server, the car owner's identity authentication fails.

[0066] It should be noted that, in the event that the car owner loses the identity key, the car owner can also provide the car owner's identity information for verification of the car owner's identity, and thus obtain the corresponding anti-theft key in the cloud server after passing the car owner's identity authentication.

[0067] Step S102, updating the anti-theft key to the replacement component to perform anti-theft matching.

[0068] Here, the replacement parts are brand new parts that have not been flashed, that is, they do not contain anti-theft keys. In order to make the replacement parts also able to achieve anti-theft matching, the anti-theft keys obtained from the cloud server are flashed to the replacement parts through after-sales diagnostic equipment, so that the replacement parts also have anti-theft functions, completing the key update of the replacement parts.

[0069] In actual applications, the anti-theft key is obtained from the cloud server and updated to the replacement parts, so that the after-sales diagnostic equipment only supports flashing permissions. During the whole process, the anti-theft key is invisible and no other modules are required to read the anti-theft key, thereby avoiding the anti-theft key from being stolen, ensuring the security of the anti-theft key, and reducing the possibility of vehicle theft.

[0070] In one embodiment, when a vehicle is offline, the offline device is connected to the vehicle, and the anti-theft key generation program is selected in the offline device. Specifically, the vehicle's identification information (for example, the vehicle's frame number) is obtained, and anti-theft keys for various anti-theft components of the vehicle are generated according to the vehicle's identification information. The anti-theft keys are flashed to the corresponding anti-theft components, and the anti-theft keys for various anti-theft components of the vehicle are uploaded to the cloud server at the same time, so that the cloud server stores the anti-theft keys for various anti-theft components of the vehicle.

[0071] In actual applications, the offline device can also generate an identity key based on the vehicle's identification information, where the identity key here is a random string generated based on an algorithm. The generated identity key can be stored in a confidentiality envelope and handed over to the owner for safekeeping when the car is purchased. It will also be uploaded to the cloud server. The cloud server can bind the anti-theft key with the corresponding identity key, so that the anti-theft key can be obtained in the cloud server through the identity key.

[0072] In one embodiment, the anti-theft component includes an anti-theft controller, a vehicle controller and an engine controller, wherein the anti-theft controller stores all anti-theft keys, the vehicle controller stores the anti-theft key of the vehicle controller, and the engine controller stores the anti-theft key of the engine controller. It is understandable that each anti-theft component has a corresponding anti-theft key, and in the process of updating the anti-theft key to the replacement component, the anti-theft key corresponding to the replacement component needs to be written into the replacement component. Specifically, the anti-theft component that needs to update the anti-theft key can be selected in the after-sales diagnostic device, and then the anti-theft key issued by the cloud server is the anti-theft key of the anti-theft component that needs to be replaced. For example, the after-sales staff can select the anti-theft component that needs to be replaced in the after-sales diagnostic device as the anti-theft controller, and then can obtain the anti-theft key corresponding to the anti-theft controller, so as to write the anti-theft key into the controller.

[0073] Figure 5 It is a schematic flow chart of another key update method provided in an embodiment of the present application. Before determining the identity key, it includes:

[0074] Step S401, obtaining a security password.

[0075] Step S402, starting the anti-theft key update process according to the security password.

[0076] Here, the security password is a kind of password used to verify identity, control access and protect security equipment from unauthorized access. It is understandable that the anti-theft key update process will affect the security of the vehicle's anti-theft system, so it is necessary to set a security password to further ensure the security of the vehicle, wherein the security password is used to determine whether the authority to perform the anti-theft key update process is available.

[0077] After the security password is obtained, the anti-theft key update process is started according to the security password. Specifically, the security password is verified. If the input security password is consistent with the set security password, the anti-theft key update process can be started.

[0078] In actual applications, the security password is set in the after-sales diagnostic device. In actual applications, the after-sales diagnostic device is connected to the vehicle to update the anti-theft key of the replaced parts in the vehicle. In the anti-theft key update process page of the after-sales diagnostic device, enter the security password. After the security password is verified, you can enter the relevant interface of the anti-theft key update and start the anti-theft key update process.

[0079] In one embodiment, when the identity key verification fails, that is, the identity of the vehicle owner cannot be determined through the identity key, there is a possibility that the vehicle has been stolen. Based on this, information can be sent to indicate that the vehicle is at risk of being stolen, and relevant staff can further verify the identity of the vehicle owner to ensure the safety of the vehicle.

[0080] In summary, the key update method of the present application can obtain the corresponding anti-theft key in the cloud server through the identity key, and the cloud server will send the anti-theft key, so that when the car owner forgets the anti-theft key, the corresponding anti-theft key can be obtained by providing the relevant identity key, without the need to replace all the anti-theft parts of the vehicle, saving after-sales costs and time. In addition, the anti-theft key is sent through the cloud, and there is no need to read the anti-theft key through other modules, so that malicious reading of the anti-theft key can be avoided, making the anti-theft key impossible to copy, reducing the risk of vehicle theft, and improving the anti-theft safety performance of the vehicle.
