Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle software technology, and more particularly to a software configuration management method, electronic device, vehicle, and storage medium. Background Technology
[0002] With the development of vehicle electronic control technology, the application of vehicle controllers or electronic control units (ECUs) is becoming increasingly widespread, and they can be installed in various configurations of multiple vehicle models. ECUs can enable various functions or adjust function parameters through configuration codes. These configuration codes can be set as needed during vehicle production, and some configuration codes can be adjusted and modified by drivers and passengers after the vehicle leaves the factory and is delivered.
[0003] During vehicle startup or operation, the electronic control unit reads configuration codes from the storage device and determines the functions to be executed and the parameters for those functions based on these codes. Various functional modules of the vehicle also need to query the configuration codes in real time. However, frequently reading the same data wastes processing resources and can easily lead to performance bottlenecks in high-concurrency scenarios. Summary of the Invention
[0004] In view of the above, it is necessary to provide a software configuration management method, electronic device and storage medium to solve the problem that frequent reading of configuration codes during vehicle startup or driving will waste processing resources and easily lead to performance bottlenecks in high-concurrency scenarios.
[0005] In a first aspect, embodiments of this application provide a software configuration management method, the method comprising: In response to a configuration code read request from an application system, determine the target configuration code corresponding to the configuration code read request; If the target configuration code is not stored in the cache of the electronic control unit, the target configuration code is retrieved from the memory, wherein the cache stores a configuration code queue, and multiple configuration codes in the configuration code queue are sorted based on access frequency; The target configuration code is sent to the application system and stored in the cache; The configuration code queue is updated by using the insertion sort algorithm to sort multiple configuration codes, including the target configuration code, in descending order according to their access frequency.
[0006] In one possible implementation, the method further includes: If the target configuration code is stored in the cache, the target configuration code is sent to the application system, and the access frequency of the target configuration code is increased.
[0007] In one possible implementation, storing the target configuration code in the cache includes: If the cache includes at least one free storage location, the target configuration code is stored in the free storage location, and the access frequency of the target configuration code is set to a preset value.
[0008] In one possible implementation, storing the target configuration code in the cache further includes: If the cache does not contain the free storage location, delete the configuration code with the lowest access frequency in the cache; The target configuration code is stored in the corresponding storage location, and the access frequency of the target configuration code is set to the preset value.
[0009] In one possible implementation, the step of using an insertion sort algorithm to sort multiple configuration codes, including the target configuration code, in descending order according to their access frequency includes: Set the first configuration code in the configuration code queue as a sorted sequence, and set the other configuration codes as an unsorted sequence; The first configuration code in the unsorted sequence is determined as the configuration code to be inserted; The access frequency of the configuration code to be inserted is compared with the access frequency of the last configuration code in the sorted sequence; If the access frequency of the configuration code to be inserted is greater than or equal to the access frequency of the last configuration code in the sorted sequence, then the last configuration code in the sorted sequence is shifted one position to the right.
[0010] In one possible implementation, the step of using the insertion sort algorithm to sort multiple configuration codes, including the target configuration code, in descending order according to their access frequency further includes: In reverse order, the access frequency of the configuration code to be inserted is compared with the access frequency of another configuration code in the sorted sequence until a configuration code with a higher access frequency is found, or the configuration codes in the sorted sequence are compared. Then the configuration code to be inserted is inserted after the configuration code with a higher access frequency, or the configuration code to be inserted is inserted at the first position in the sorted sequence. Increase the length of the sorted sequence by 1, and decrease the length of the unsorted sequence by 1.
[0011] In one possible implementation, the method further includes: The access frequency of all configuration codes in the cache is traversed. If the access frequency of a configuration code is greater than a preset threshold, the access frequency of the configuration code is reduced. If the access frequency of the configuration code is less than or equal to a preset threshold, the access frequency of the configuration code will remain unchanged.
[0012] Secondly, embodiments of this application provide an electronic device, the electronic device including a memory and a processor; wherein, the memory is used to store program instructions; the processor is used to read and execute the program instructions stored in the memory, and when the program instructions are executed by the processor, the electronic device performs the above-described software configuration management method.

[0015] Fifthly, embodiments of this application provide a computer storage medium that, when the program instructions are run on an electronic device or a vehicle, causes the processor of the electronic device or the vehicle to execute the above-described software configuration management method.
[0016] The software configuration management method, device, electronic device, vehicle, and storage medium provided in this application embodiment can pre-cache configuration codes, thereby shortening the function call chain of the configuration code query process under various operating conditions, shortening the configuration code query time, and effectively improving the configuration code query efficiency. Furthermore, the insertion sort algorithm can be used to sort multiple pre-cached configuration codes according to their access frequency, thereby placing the configuration codes with higher access frequencies at the beginning of the query loop, increasing the probability of finding the actually needed configuration code, and further improving the configuration code query efficiency.

For example, at least one of a, b, or c can represent: a, b, c, a and b, a and c, b and c, and a, b, and c. Where there is no conflict, the following embodiments and features described herein can be combined with each other.
[0027] With the development of vehicle electronic control technology, the application of vehicle controllers or electronic control units (ECUs) is becoming increasingly widespread, and they can be installed in various configurations of multiple vehicle models. ECUs can enable various functions or adjust function parameters through configuration codes. These configuration codes can be set as needed during vehicle production, and some configuration codes can be adjusted and modified by drivers and passengers after the vehicle leaves the factory and is delivered.
[0028] When the vehicle starts, the electronic control unit (ECU) reads the configuration code from the storage module and selects whether to execute a function and with what parameters based on the configuration code. During vehicle operation, the ECU also needs to read the configuration code from the storage module to select whether to execute a function and with what parameters. Therefore, various application subsystems of the vehicle need to query the configuration code in real time and select parameters to execute or disable functions accordingly. However, frequently reading the same data wastes processing resources and can easily lead to performance bottlenecks in high-concurrency scenarios.
[0029] To address the issue that frequent reading of configuration codes during vehicle startup or operation wastes processing resources and can lead to performance bottlenecks in high-concurrency scenarios, this application provides a software configuration management method. This method pre-caches configuration codes, thereby shortening the function call chain during configuration code lookup under various operating conditions, reducing lookup time, and effectively improving lookup efficiency. Furthermore, it utilizes an insertion sort algorithm to sort the pre-cached configuration codes according to their access frequency, placing frequently accessed configuration codes at the beginning of the query loop, increasing the probability of finding the required configuration code, and further improving lookup efficiency.
[0030] See Figure 1The diagram shown illustrates an application scenario of a software configuration management method provided in an embodiment of this application. The software configuration management method in this embodiment is applied to a software configuration management system 100, which includes, but is not limited to, at least one application system 101, at least one electronic control unit 102, and a memory 103. The application system 101 is used to implement vehicle control functions, such as body control, battery management, and central control functions. Each application system 101 is communicatively connected to its corresponding electronic control unit 102, which configures the functions of the application system 101 based on configuration codes. The memory 103 stores multiple configuration codes, which are used to enable the functions of the application system 101 or adjust its function parameters. The electronic control unit 102 includes a cache 104 for temporarily storing the configuration codes read by the application system 101.
[0031] See Figure 2 The diagram shown is a flowchart of a software configuration management method provided in an embodiment of this application. The method is applied to an electronic device or vehicle and includes: S101, in response to the configuration code reading request from the application system, determine the target configuration code corresponding to the configuration code reading request.
[0032] In one embodiment of this application, the memory pre-stores the correspondence between application systems and configuration codes. When an application system decides on the function to be executed or the parameters of the function to be executed, it sends a configuration code read request to the electronic control unit. When the electronic control unit receives the configuration code read request sent by the application system, it determines the target configuration code corresponding to the application system based on the application system and the correspondence between the application system and the configuration code.
[0033] S102, determine whether the target configuration code is stored in the cache of the electronic control unit. If the target configuration code is not stored in the cache, proceed to S103; if the target configuration code is stored in the cache, proceed to S105.
[0034] In one embodiment of this application, the cache stores a configuration code queue, and the multiple configuration codes in the configuration code queue are sorted in descending order based on access frequency; that is, each configuration code has a corresponding access frequency. The target configuration code is compared one by one with the multiple configuration codes. If the target configuration code is the same as any configuration code in the cache, it is determined that the target configuration code is stored in the cache. If the target configuration code is different from all configuration codes in the cache, it is determined that the target configuration code is not stored in the cache.
[0035] S103: Obtain the target configuration code from the memory, send the target configuration code to the application system, and store the target configuration code in the cache.
[0036] In one embodiment of this application, if the target configuration code is not stored in the cache, the target configuration code is retrieved from the memory, returned to the application system, and stored in the cache.
[0037] In one embodiment of this application, the cache includes multiple storage locations for temporarily storing configuration codes. After the target configuration code is returned to the application system, it is determined whether the cache includes any free storage locations. If the cache includes at least one free storage location, the target configuration code is stored in the free storage location, and the access frequency of the target configuration code is set to a first preset value. If the cache does not include any free storage locations, the configuration code with the lowest access frequency in the cache is deleted, the target configuration code is stored in the storage location corresponding to the configuration code with the lowest access frequency, and the access frequency of the target configuration code is set to the first preset value. For example, the first preset value is 1.
[0038] S104: Use the insertion sort algorithm to sort multiple configuration codes, including the target configuration code, in descending order according to their access frequency, and update the configuration code queue.
[0039] In one embodiment of this application, multiple configuration codes in the cache are sorted in descending order according to their access frequency at preset intervals, thereby updating the configuration code queue in real time. Thus, after the target configuration code is stored in the cache, it also participates in the sorting process. Before re-sorting, the target configuration code is stored in any previously empty storage location or in the storage location of the most recently deleted configuration code.
[0040] See Figure 3 The diagram shown is a flowchart of sorting configuration codes according to an embodiment of this application.
[0041] S201, set the first configuration code in the configuration code queue to the sorted sequence.
[0042] For example, if the current configuration code queue is [APF2, S322A, 00235, 0YC25, 681G3], and 0YC25 is the target configuration code, then [APF2] will be set as the sorted sequence.
[0043] S202, set other configuration codes to an unsorted sequence.
[0044] Based on the example of the configuration code queue above, [S322A, 00235, 0YC25, 681G3] is set as an unsorted sequence.
[0045] S203, determine the first configuration code in the unsorted sequence as the configuration code to be inserted.
[0046] Based on the example of the configuration code queue above, S322A is identified as the configuration code to be inserted.
[0047] S204: Compare the access frequency of the configuration code to be inserted with the access frequency of the last configuration code in the sorted sequence to determine whether the access frequency of the configuration code to be inserted is greater than or equal to the access frequency of the last configuration code in the sorted sequence. If the access frequency of the configuration code to be inserted is greater than or equal to the access frequency of the last configuration code in the sorted sequence, the process proceeds to S205; if the access frequency of the configuration code to be inserted is less than the access frequency of the last configuration code in the sorted sequence, the process proceeds to S206.
[0048] Based on the example of the configuration code queue above, the access frequency of S322A is compared with the access frequency of APF2.
[0049] S205, shift the last configuration code in the sorted sequence one position to the right.
[0050] Based on the example of the configuration code queue above, if the access frequency of S322A is greater than or equal to the access frequency of APF2, then APF2 will be shifted one position to the right.
[0051] S206, insert the configuration code to be inserted after the last configuration code.
[0052] Based on the example of the configuration code queue above, if the access frequency of S322A is less than the access frequency of APF2, then S322A is inserted after APF2.
[0053] S207, increase the length of the sorted sequence by 1, and decrease the length of the unsorted sequence by 1.
[0054] S208, determine if there is a configuration code before the last configuration code in the sorted sequence. If there is a configuration code before the last configuration code in the sorted sequence, proceed to S211; if there is no configuration code before the last configuration code in the sorted sequence, proceed to S209.
[0055] S209, insert the configuration code to be inserted before the last configuration code.
[0056] Based on the example of the configuration code queue above, if there is no configuration code before the last configuration code in the sorted sequence, then S322A is inserted before APF2.
[0057] S210, increase the length of the sorted sequence by 1, and decrease the length of the unsorted sequence by 1.
[0058] S211, following a reverse order, compare the access frequency of the configuration code to be inserted with the access frequency of another configuration code in the sorted sequence to determine whether the access frequency of the configuration code to be inserted is greater than or equal to the access frequency of the other configuration code. If the access frequency of the configuration code to be inserted is greater than or equal to the access frequency of the other configuration code, the process proceeds to S212; if the access frequency of the configuration code to be inserted is less than the access frequency of the other configuration code, the process proceeds to S213.
[0059] Based on the example of the configuration code queue above, if there is a configuration code before the last configuration code in the sorted sequence, the access frequency of S322A is compared with the access frequency of the configuration codes before APF2.
[0060] S212, shift another configuration code one position to the right.
[0061] S213, insert the configuration code to be inserted after another configuration code.
[0062] S214, increase the length of the sorted sequence by 1, and decrease the length of the unsorted sequence by 1.
[0063] S215, determine if a configuration code exists before the other configuration code. If a configuration code exists before the other configuration code, proceed to S211; if no configuration code exists before the other configuration code, proceed to S216.
[0064] S216, insert the configuration code to be inserted before another configuration code.
[0065] In step S217, the length of the sorted sequence is increased by 1, and the length of the unsorted sequence is decreased by 1. Then, the process returns to S203 and loops through S203-S217 until all configuration codes in the unsorted queue are sorted.
[0066] In other words, the access frequency of the configuration code to be inserted is compared with the access frequency of another configuration code in the sorted sequence in reverse order, until a configuration code with a higher access frequency is found, or the configuration codes in the sorted sequence are compared. Then the configuration code to be inserted is inserted after the configuration code with a higher access frequency, or the configuration code to be inserted is inserted at the first position in the sorted sequence.
[0067] S105, send the target configuration code to the application system and increase the access frequency of the target configuration code.
[0068] In one embodiment of this application, if the target configuration code is stored in the cache, the target configuration code is directly returned to the application system, and the access frequency of the target configuration code is increased. For example, the access frequency of the target configuration code is increased by a second preset value, where the second preset value is 1, 2, or other values.
[0069] The embodiments described above in this application shorten the function call chain in the process of querying configuration codes under various operating conditions by pre-caching configuration codes. Only the configuration management system needs to be called, instead of the storage management system every time, thus shortening the query time and effectively improving the query efficiency. Furthermore, the insertion sort algorithm can be used to sort the pre-cached configuration codes according to their access frequency, thereby placing the configuration codes with higher access frequencies at the beginning of the query loop, increasing the probability of finding the actually needed configuration code, further improving the query efficiency, and thus avoiding performance bottlenecks in the control unit under high concurrency scenarios.
[0070] This application embodiment reduces system load and runtime of configuration management functions through efficient dynamic management methods, achieving the original functions with lower performance and reducing hardware costs. At the same time, it maintains system flexibility and minimizes coupling between modules.
[0071] See Figure 4 The diagram shown is a flowchart of a software configuration management method provided in another embodiment of this application. The method is applied to an electronic device or vehicle and includes: S301, in response to the configuration code read request from the application system, determines the target configuration code corresponding to the configuration code read request.
[0072] S302, determine whether the target configuration code is stored in the cache of the electronic control unit. If the target configuration code is not stored in the cache, proceed to S303; if the target configuration code is stored in the cache, proceed to S305.
[0073] S303: Obtain the target configuration code from the memory, send the target configuration code to the application system, and store the target configuration code in the cache.
[0074] S304: The insertion sort algorithm is used to sort multiple configuration codes, including the target configuration code, in descending order according to their access frequency, and the configuration code queue is updated.
[0075] S305, send the target configuration code to the application system and increase the access frequency of the target configuration code.
[0076] The specific implementation methods of S301-S305 are the same as those of S101-S105, and will not be described in detail here.
[0077] S306, iterate through the storage locations in the cache.
[0078] S307, determine whether the currently traversed storage location stores a configuration code. If the currently traversed storage location stores a configuration code, the process proceeds to S308; if the currently traversed storage location does not store a configuration code, the process returns to S306.
[0079] S308, determine whether the access frequency of the configuration code is greater than a preset threshold. If the access frequency of the configuration code is greater than the preset threshold, the process proceeds to S309; if the access frequency of the configuration code is less than or equal to the preset threshold, the process proceeds to S310. For example, the preset threshold is 1, 2, or other values.
[0080] S309 reduces the frequency of accessing configuration codes.
[0081] In one embodiment of this application, if the access frequency of the configuration code is greater than a preset threshold, the access frequency of the configuration code is reduced. For example, the access frequency of the configuration code is reduced by a third preset value, which can be 1.
[0082] S310 maintains the same access frequency for configuration codes.
[0083] In one embodiment of this application, if the access frequency of the configuration code is less than or equal to a preset threshold, the access frequency of the configuration code is kept unchanged.
[0084] In one embodiment of this application, after each traversal of a storage location is completed, it is determined whether all storage locations in the cache have been traversed. If all storage locations in the cache have been traversed, the process ends. If there are untraversed storage locations in the cache, the process returns to S306.
[0085] The above embodiments of this application reduce cache pollution by actively reducing access frequency, thus avoiding the situation where data that is frequently accessed in the early stages but no longer used later occupies the cache for a long time.

[0088] The determination module 201 is used to determine the target configuration code corresponding to the configuration code reading request in response to the configuration code reading request of the application system.
