Description

Technical Field

[0001] The present invention belongs to the field of data transmission and management in the automotive industry, and more specifically, relates to a novel data transmission and management method. Background Art

[0002] With the vigorous development of the automotive industry, the competition in the automotive industry is high, and the product development cycle is rapidly accelerated. In addition, the current models have many functions and fast iterations, and the release of new versions of various controllers has also increased. The problem that follows is that the consistency of software and hardware related data transmission and data compatibility are put to the test.

[0003] The current method for transmitting software and hardware data involves product engineers submitting test data to the data submission system. Once the data passes the test, the test engineer issues a report indicating that the data has passed the test. Depending on how the software is used, the product engineer submits the qualified software to the production management system, after-sales diagnostic system, and OTA data management system. This poses the risk of errors when the qualified data is manually transferred to other systems, such as errors in the transfer process version, inconsistent data transmission between systems, and incompatible data transmission between systems.

[0004] In order to solve the problems that arise during data transmission, a new data transmission and management method is imminent. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: to overcome the shortcomings of the existing technology and provide a new data transmission and management method, in which data transmission is completely online and has been tested and verified in production, and the data is unique, safe and reliable; by statistically analyzing the data and reflecting the results in after-sales service; during after-sales or OTA upgrades, combined with the current status of the vehicle and combined with the data statistical analysis results, one vehicle one push is achieved, making the software and hardware of each model highly compatible.

[0006] In order to solve the above problems, the present invention proposes a new data transmission and management method, which includes the following main steps: 1. Upload the data to be tested: Product engineers upload the data to be tested (including vehicle material number, controller part number, software and hardware version numbers to be tested, and software flash package to be tested) to the data testing system.

[0007] 2. Testing and judgment: The test engineer tests the uploaded data to be tested and determines whether the data needs to be uploaded to the data management system after passing the test; If the test fails, the task is terminated and the test fails.

[0008] 3. Data upload and management: If the data needs to be uploaded to the data management system, it will be submitted directly to the data management system through the data submission system without the need for offline data transmission; If the data does not need to be uploaded, it will be switched to offline maintenance.

[0009] 4. Data transmission and validation: After the data is uploaded to the data management system, it is transferred to the production management system according to the project or trial installation plan. At this time, the data is in the waiting stage; Based on the timing of the SOP (Standard Operating Procedure), decide whether to take effect directly or after vehicle test installation; The trial installation application submitted before the trial installation must include the specific information of the trial installation controller.

[0010] 5. After-sales data processing: After the data is effective in the production management system, whether it needs to be uploaded to the after-sales data processing system is determined based on whether the vehicle is customer-oriented; The data uploaded to the after-sales data processing system includes the vehicle material number, VIN code, each controller part number, and each controller's software and hardware version number; The system differentiates the data and automatically sorts out the optimal set of software and hardware versions for use in after-sales or OTA upgrades.

[0011] 6. Precision upgrade: During after-sales or OTA upgrades, targeted data push upgrades are implemented based on the vehicle's current status and data statistical analysis results.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. Data security and reliability: Data transmission is completely online and has undergone test verification and production validation. The data is unique, secure and reliable. By statistically analyzing the data and reflecting the results in after-sales service, after-sales or OTA upgrades, the current status of the vehicle is combined with the results of data statistical analysis to achieve a one-vehicle-one-push service, making the software and hardware of each model highly compatible.

[0013] 2. Statistical analysis application: The after-sales data processing system has the ability to conduct statistical analysis of data and apply the statistical analysis results to after-sales service, thereby improving the pertinence and efficiency of after-sales service.

[0014] 3. High compatibility: The after-sales data processing system can match the vehicle's material number according to the vehicle's VIN code and compare it with the optimal software and hardware version in the system, achieving precise upgrades for each vehicle and ensuring high compatibility between software and hardware of each model. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 is a flow chart of the present invention; DETAILED DESCRIPTION

[0016] The present invention will be further described below in conjunction with the accompanying drawings: The terms used in the detailed description are intended solely to facilitate understanding of the technical solutions described herein by those skilled in the art based on the visual orientation of the accompanying drawings. Unless otherwise specified or limited, the terms "dispose," "install," and "connect" are to be interpreted broadly, and those skilled in the art will understand their specific meanings within the present invention based on the specific circumstances.

[0017] 1. Upload the data to be tested: Product engineers upload the test data (including vehicle material number, controller part number, software and hardware version numbers, and software flash package) to the data testing system.

[0018] 2. Testing and judgment: Test engineers test the uploaded data for operational stability and compatibility. After passing the test, they determine whether the data needs to be uploaded to the data management system. If the test fails, the task is terminated and the test fails.

[0019] 3. Data upload and management: If data needs to be uploaded to the data management system, it can be submitted directly to the data management system through the data submission system without the need for offline data transmission; If the data does not need to be uploaded, it will be switched to offline maintenance.

[0020] 4. Data transmission and validation: After the data is uploaded to the data management system, it will be transferred to the production management system according to the project or trial installation plan. At this time, the data is in the waiting stage; Based on the timing of the SOP (Standard Operating Procedure), decide whether to take effect immediately or after successful vehicle test installation; The trial installation application submitted before the trial installation must include specific information about the trial installation controller, including the vehicle material number of the trial installation model, the trial installation part number, the trial installation software and hardware version numbers, and the part numbers and software and hardware version numbers of other controllers associated with the trial installation.

[0021] 5. After-sales data processing: Receive uploaded data: The uploaded data includes the vehicle material number, VIN code, each controller part number and each controller software and hardware version number; Differentiate the uploaded data according to the rules: for the same vehicle material number, identify the vehicle VIN code contained therein; Compare the software and hardware of each controller with the initial data through a preset hardware version matching database; the database stores the historical records and compatible identification of each controller's hardware version; During the process of sorting out the optimal versions for software matching, a compatibility scoring model is used to score different software combinations, and the combination with the highest score is selected as the optimal version or optimal version set. When the hardware of each controller in the same vehicle part number remains unchanged from the initial data, for example, if the entire vehicle hardware remains in its factory-installed state without repair or replacement, the optimal software version will be automatically determined based on the matching and compatibility of the software between the controllers. When the hardware of individual controllers within the same vehicle part number changes compared to the initial data, such as when individual vehicle hardware devices undergo repair or replacement due to a fault and are no longer consistent with the initial factory data, the system automatically determines the optimal hardware and software version set to suit each controller's hardware and software versions, based on the hardware and software compatibility of each controller and between controllers.

[0022] 6. Precision upgrade: Data processing method for after-sales or OTA upgrades Before upgrading, read the vehicle's VIN and the software and hardware version numbers of each controller using a diagnostic instrument or OTA node, and upload the data to the after-sales diagnostic system or OTA data management platform. The after-sales diagnostic system or OTA data management platform sends an upgrade request to the after-sales data processing system; the request packet reads the vehicle VIN code and the software and hardware version numbers of each controller; The after-sales data processing system matches the vehicle's material number with the VIN code and compares the software and hardware version numbers of each controller of the requested model with the optimal software and hardware version set stored in the system; Based on the comparison results, the data that needs to be upgraded is pushed to the after-sales diagnostic system or OTA data management platform for targeted upgrades. During after-sales or OTA upgrades, targeted data push upgrades are implemented based on the vehicle's current status and data statistical analysis results.

[0023] Finally, although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
