Description

Technical Field

[0001] The present invention relates to the technical field of digital car keys, and in particular to a method and system for processing and calling back Bluetooth commands of digital car keys. Background Art

[0002] Digital car keys are a modern solution that uses digital technology to unlock and start vehicles. Specifically, digital car keys digitize the original physical car keys (sensing keys or mechanical keys). The digital car key App (Application) in the smart device communicates with the BLE (Bluetooth Low Energy) device in the vehicle via Bluetooth or other means, allowing the smart device to realize the car key function, thereby eliminating the need for users to carry physical keys separately when going out.

[0003] In order to achieve the above functions, relevant developers need to write command processing and authentication logic. The current typical command processing and authentication logic is: after the digital car key App receives the command from the BLE device, the developer manually parses the command to clarify the type and content of the command. After the parsing is completed, the developer selects the target processing logic from multiple preset processing logics according to the command type. Each command corresponds to a different processing flow.

[0004] However, due to the differences between iOS and Android mobile operating systems, developers need to write separate instruction processing codes for the two mobile operating systems, which makes the code development and maintenance costs of developers high; and because the current solution requires developers to manually parse instructions and select processing logic, it further increases the code development costs of developers and is prone to code errors. Therefore, how to reduce the code development and maintenance costs of developers and improve code accuracy has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] In view of this, in order to solve the above technical problems, the present invention provides a digital car key Bluetooth command processing and callback method and system.

[0006] The present invention adopts the following technical solution:

[0033] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0034] Example

[0035] Figure 1 FIG. 1 is a flow chart of a method for processing and calling back a Bluetooth command of a digital car key provided by an embodiment of the present invention. Figure 1 As shown, this process includes:

[0036] Step 101: The BLE device sends a request command to the digital car key App of the smart device through its Bluetooth module.

[0037] Specifically, a Bluetooth connection is established between the BLE device and the smart device, and the BLE device can send a request instruction to the digital car key App of the smart device through the Bluetooth connection. The request instruction can specifically be a request to unlock the vehicle or a request for authentication.

[0038] The smart device may be a smart phone or a smart watch. The mobile operating system in the smart device may be an iOS (iPhone Operating System) mobile operating system or an Android (Android Operating System) mobile operating system.

[0039] Step 102: After receiving the request instruction, the digital car key App passes the request instruction to the SDK of the smart device by calling the sendCommand method in the SDK; the iOS mobile operating system and the Android mobile operating system use a unified sendCommand method.

[0040] Specifically, the iOS mobile operating system and the Android mobile operating system use different SDKs, but both provide a unified sendCommand method for processing the sending, parsing, and callback of instructions. That is, the SDK provides a unified interface and logical structure on different platforms (iOS mobile operating system and Android mobile operating system), so that developers only need to care about interface calls without having to worry about the underlying differences.

[0041] The sendCommand method receives two parameters: a digital car key identifier and a request command (command). The digital car key identifier is a digital car key ID, and the digital car key ID can specifically be a vehicle ID (cardId).

[0042] Step 103: The SDK generates a processing result of the request instruction.

[0043] In the embodiment of the present invention, the processing result of the SDK generating the request instruction may specifically include:

[0044] (1031) After receiving the request instruction, the SDK parses the request instruction and obtains the parsing result.

[0045] Specifically, after receiving the request instruction, the SDK parses the request instruction and confirms the instruction type of the request instruction, such as unlocking, vehicle condition inquiry or Bluetooth authentication request.

[0046] (1032) The SDK selects a target processing logic from a plurality of preset processing logics based on the analysis result.

[0047] Specifically, the SDK selects a target processing logic that matches the current request instruction from multiple preset processing logics based on the analysis results. For example, if the request instruction is an unlock request, the corresponding target processing logic is to execute the unlock operation; or if the request instruction is a Bluetooth authentication request, the corresponding target processing logic is to complete the authentication.

[0048] (1033) The SDK generates a processing result of the request instruction based on the target processing logic.

[0049] In addition, the digital car key Bluetooth instruction processing and callback method of the present invention may also include: the SDK automatically performs instruction security authentication during the process of parsing the request instruction.

[0050] Specifically, the SDK performs Bluetooth security authentication to ensure the security of data transmission during communication. By encrypting and parsing the data, security vulnerabilities in the instruction transmission process are eliminated.

[0051] Compared with the existing solution in which developers parse request instructions, the present invention can avoid the situation in which developers introduce security vulnerabilities during instruction parsing, so that the present invention improves communication security.

[0052] In addition, in this scenario, the processing result generated by the SDK may include the Bluetooth communication status code, the processed instruction information and the authentication result. Since the processing result provides detailed authentication and instruction execution results, the present invention ensures the safety and traceability of the operation.

[0053] In a specific example, the processing results are as follows:

[0054] sendCommand result code=0;

[0055] sendCommand result message = Authentication command executed successfully;

[0056] sendCommand result commandType=0101.

[0057] Step 104: The SDK returns the processing result to the digital car key App through a callback function.

[0058] Specifically, the SDK provides a sendCommand method that accepts a callback function as a parameter. When the command is executed, the SDK calls the callback function and passes a result object (i.e., the processing result) to the callback function. For the iOS mobile operating system, the result object can be of the CarKeySDKResult type, and for the Android mobile operating system, the result object can be of the Result type.

[0059] Step 105: The digital car key App feeds back the processing result to the BLE device.

[0060] Step 106: The BLE device responds to the processing result and generates a response result.

[0061] The present invention adopts the above-mentioned technical scheme. Since both the iOS mobile operating system and the Android mobile operating system use a unified sendCommand method, that is, the iOS mobile operating system and the Android mobile operating system use a unified instruction processing interface and callback mechanism, thus ensuring the consistency of the development process, so that the present invention does not need to write respective instruction processing codes for the iOS mobile operating system and the Android mobile operating system, so that the present invention can reduce the code development and maintenance costs of developers; and, through the unified sendCommand method, there is no need for developers to manually parse instructions and select processing logic, so that the present invention further reduces the code development costs of developers and improves code accuracy.

[0062] Furthermore, compared to the existing solution in which developers parse request instructions, the present invention automatically performs instruction security authentication during the process of parsing request instructions through SDK, so that the present invention can avoid the situation where developers introduce security vulnerabilities during the instruction parsing process, thereby improving communication security.

[0063] In the embodiment of the present invention, after the BLE device responds to the processing result and generates a response result, the digital car key Bluetooth instruction processing and callback method of the present invention may also include:

[0064] The BLE device sends the response result back to the digital car key App.
