Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle technology, and in particular to a method, system, vehicle, device and medium for protecting vehicle electrical inspection data. Background Technology
[0002] During automobile manufacturing, an electrical test is required before vehicles are put off the production line to ensure the normal operation of the electronic control system. During this process, the electrical tester sends an electrical test command to the vehicle controller. The vehicle controller writes the calibration data or configuration data in the electrical test command into its own storage device. However, if a power outage or system failure occurs during data writing, the electrical test data may be incomplete, damaged, or lost, which will affect the use of the electrical test data and cause abnormal vehicle functions. Summary of the Invention
[0003] Based on this, the present invention provides a method, system, vehicle, equipment and medium for protecting vehicle electrical inspection data. By storing data in duplicate and combining it with integrity check value calculation, the risk of data unavailability under single point of failure can be avoided, thereby improving the integrity and reliability of electrical inspection data storage.
[0004] Firstly, a method for protecting vehicle electrical inspection data is provided, wherein the vehicle's storage system is configured with two data copies, with a status flag indicating the currently used data copy, the currently used data copy being a first data copy and the other data copy being a second data copy. The method for protecting the vehicle's electrical inspection data includes: The target controller receives the electrical testing command sent by the electrical testing instrument; According to the electrical testing command sent by the electrical testing instrument, the data to be written is obtained, including calibration data and / or configuration data; Write the data into the second data copy and calculate the integrity check value of the second data copy; Update the status flag to point to the second data copy; The data is synchronized to the first data copy.
[0005] Furthermore, the first data copy and the second data copy are physically isolated and stored separately.
[0006] Furthermore, the status flag is a hexadecimal value that is neither all 0s nor all 1s, and the status flag is physically isolated from the first data copy and the second data copy.
[0007] Furthermore, after synchronizing the data to the first data copy, the method further includes: Update the status flag to point to the first data copy.
[0008] Furthermore, it also includes: According to the data read instruction, read data from the data copy pointed to by the status flag bit.
[0009] Further, the step of reading data from the data copy pointed to by the status flag bit according to the data read instruction includes: Verify the integrity check value of the data copy pointed to by the status flag bit; If the integrity check value of the data copy pointed to by the status flag passes the verification, then data is read from the data copy pointed to by the status flag. If the verification fails, then the status flag is pointed to another data copy, and the integrity check value of the other data copy is verified. If the integrity check value of the other data copy passes the verification, data is read from the other data copy; if the verification fails, an error status is returned.
[0010] Secondly, a protection system for vehicle electrical inspection data is provided. The vehicle's storage system is configured with two data copies, with a status flag indicating the currently used data copy. The currently used data copy is a first data copy, and the other data copy is a second data copy. The vehicle electrical inspection data protection system includes: The receiving module is used by the target controller to receive the electrical inspection command sent by the electrical inspector; The acquisition module is used to obtain the data to be written according to the electrical testing command sent by the electrical testing instrument, the data including calibration data and / or configuration data; The storage and computing module is used to write the data into the second data copy and calculate the integrity verification value of the second data copy; The update module is used to update the status flag bit to point to the second data copy; A synchronization module is used to synchronize the data to the first data copy.
[0011] Thirdly, a vehicle is provided, including: a protection system for the vehicle's electronic inspection data as described in the second aspect above.
[0012] Fourthly, a computer device is provided, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the program, it implements the method for protecting the electronic inspection data of a vehicle according to the first aspect described above.
[0013] Fifthly, a computer-readable storage medium is provided, including a memory and a computer program stored on the memory and executable on a processor, wherein when executed by the processor, the program implements the method for protecting the electronic inspection data of a vehicle according to the first aspect described above.
[0014] In the embodiments of this application, the target controller first receives the electrical inspection command sent by the electrical inspection instrument; then, based on the electrical inspection command sent by the electrical inspection instrument, it obtains the data to be written, which includes calibration data and / or configuration data; next, the data is written to a second data copy, and the integrity check value of the second data copy is calculated; then, the status flag is updated to point to the second data copy; finally, the data is synchronized to the first data copy.

Detailed Implementation
[0016] The present application will now be described in further detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the application. Furthermore, it should be noted that, for ease of description, only the parts relevant to the application are shown in the accompanying drawings.
[0017] It should be noted that, unless otherwise specified, the embodiments and features of the embodiments in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0018] The following describes in detail, with reference to the accompanying drawings, a method, system, vehicle, device, and medium for protecting vehicle electrical inspection data according to embodiments of this application.
[0019] Figure 1 This is a flowchart of a method for protecting vehicle electrical inspection data according to an embodiment of this application. Figure 1 As shown, according to an embodiment of the present application, a method for protecting vehicle electrical inspection data includes a storage system for the vehicle with two data copies configured, each with a status flag indicating the currently used data copy. The currently used data copy is the first data copy, and the other data copy is the second data copy.
[0020] In one embodiment of this application, the first data copy and the second data copy are physically isolated to reduce the risk of both data copies being corrupted simultaneously.
[0021] In one embodiment of this application, the status flag is a hexadecimal value that is neither all 0s nor all 1s to prevent misjudgment during storage device initialization; the status flag is physically isolated from the first data copy and the second data copy.
[0022] The method for protecting the vehicle's electrical inspection data includes the following steps: S101: The target controller receives the electrical inspection command sent by the electrical inspection instrument.
[0023] like Figure 2 As shown, the electrical testing instrument is connected to the target controller. When the vehicle is undergoing electrical testing after leaving the production line, the target controller receives the electrical testing command sent by the electrical testing instrument.
[0024] S102: Based on the electrical test command sent by the electrical tester, obtain the data to be written, the data including calibration data and / or configuration data.
[0025] S103: Write the data into the second data copy and calculate the integrity check value of the second data copy.
[0026] The integrity check value refers to a fixed-length check value calculated based on the data content within the data copy after the data is written, using a specific algorithm such as cyclic redundancy check or hash algorithm, and stored together with the data content.
[0027] S104: Update the status flag to point to the second data copy.
[0028] S105: Synchronize the data to the first data copy.
[0029] The data synchronization operation can be performed immediately after updating the status flag, or it can be performed asynchronously, such as when the system is idle or under low load, to avoid affecting real-time performance.
[0030] In one embodiment of this application, after synchronizing the data to the first data copy, the method further includes: updating the status flag bit to point to the first data copy.
[0031] In one embodiment of this application, the method further includes: reading data from the data copy pointed to by the status flag bit according to the data read instruction.
[0032] In one embodiment of this application, reading data from the data copy pointed to by the status flag bit according to the data read instruction includes: verifying the integrity check value of the data copy pointed to by the status flag bit; if the integrity check value of the data copy pointed to by the status flag bit passes the verification, then reading data from the data copy pointed to by the status flag bit; if the verification fails, then pointing the status flag bit to another data copy and verifying the integrity check value of the other data copy; if the integrity check value of the other data copy passes the verification, then reading data from the other data copy; if the verification fails, then returning an error status.
[0033] Specifically, when data needs to be read from a data copy, the current integrity check value is calculated using the same algorithm as described above, based on the data content stored in that data copy. This value is then compared with a pre-stored integrity check value. If they match, the integrity check of that data copy has passed verification, and data can be read from it. If they differ, verification has failed, and the status flag is set to another data copy, which is then verified in the same way. If both data copies fail verification, an error status is returned. This method ensures that read operations are performed on a complete data copy, thereby improving the reliability of electronic inspection data reading.
[0034] According to the vehicle electrical inspection data protection method of the present invention, the target controller first receives the electrical inspection command sent by the electrical inspection instrument; then, according to the electrical inspection command sent by the electrical inspection instrument, it obtains the data to be written, which includes calibration data and / or configuration data; next, it writes the data to a second data copy and calculates the integrity check value of the second data copy; then, it updates the status flag bit to point to the second data copy; finally, it synchronizes the data to the first data copy. Thus, by storing data in dual copies and combining the integrity check value calculation, the risk of data unavailability under a single point of failure can be avoided, improving the integrity and reliability of electrical inspection data storage.

[0036] According to the vehicle electrical inspection data protection system of this application embodiment, the target controller first receives the electrical inspection command sent by the electrical inspection instrument; then, based on the electrical inspection command sent by the electrical inspection instrument, it obtains the data to be written, which includes calibration data and / or configuration data; next, it writes the data to a second data copy and calculates the integrity check value of the second data copy; then, it updates the status flag bit to point to the second data copy; finally, it synchronizes the data to the first data copy. Thus, by storing data in dual copies and combining it with the integrity check value calculation, the risk of data unavailability under a single point of failure can be avoided, improving the integrity and reliability of electrical inspection data storage.
