[0027] AUTOSAR CP, a standardized framework widely used in ECU application development, improves communication efficiency and application reusability between different ECUs through modular design and standardized interfaces. However, its general and large functional modules and protocol stack design have problems such as low resource utilization and high dimensionality in resource-constrained embedded environments.

[0028] Specifically, the massive feature set of AUTOSAR CP means that even if an ECU only requires a small subset of features, the entire framework is loaded. This results in a large amount of unused code and data structures occupying significant memory space, impacting the ECU's operational efficiency and real-time responsiveness. Furthermore, the complex code architecture and configuration options within AUTOSAR CP complicate application development and maintenance. Developers not only need to deeply understand the details of each module but also must adjust module configurations to suit specific ECU requirements while preventing the introduction of new compatibility issues or functional redundancy, further increasing the complexity and cost of system integration.

[0029] The method embodiment can be executed in an electronic device or similar computing device including a memory and a processor. Taking running on a computer terminal as an example, the computer terminal may include one or more processors (processors may include but are not limited to a central processing unit (CPU), a graphics processing unit (GPU), a digital signal processing (DSP) chip, a microcontroller unit (MCU), a programmable logic device (Field Programmable Gate Array, FPGA), a neural network processor (NPU), a tensor processing unit (TPU), an artificial intelligence (AI) type processor, etc.) and a memory for storing data.

[0033] According to an embodiment of the present invention, a method embodiment of a vehicle application adjustment method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0034] Figure 1 is a flow chart of a vehicle application adjustment method according to one embodiment of the present invention. Figure 1 As shown, the method includes the following steps:

[0035] Step S11, obtaining a target dependency library and an initial application corresponding to a target vehicle, wherein the target dependency library includes a plurality of functional modules, the plurality of functional modules are used to adjust and process the initial application, and the initial application is used to control the target vehicle to perform a vehicle control task;

[0036] The core of this target dependency library is to provide a series of streamlined and optimized functional modules to address the low resource utilization and difficult development and maintenance challenges faced by ECU applications in resource-constrained environments. Specifically, this target dependency library includes optimized implementations for memory management, timer operations, data structure processing, and other functions. Each module can be directly reused in ECU applications, reducing redundant code, lowering memory usage, and improving system efficiency and responsiveness.

[0037] For example, the memory management module can use memory pool technology to reduce the overhead of dynamic memory allocation and release, while the timer module can improve the accuracy and responsiveness of time-sensitive applications by optimizing time event scheduling strategies. The data structure module can use high-performance circular queues, doubly linked lists, and hash maps to enable the ECU to process large amounts of data more smoothly and quickly. The introduction of the target dependency library provides ECU applications with a more refined and powerful toolbox, helping them implement their functions while minimizing the consumption of system resources and ensuring good operation and performance even in resource-constrained environments.

[0038] The initial application corresponding to the above-mentioned target vehicle refers to the original software code designed for a specific car model and used to control and manage the operation of its electronic systems (such as engine control, braking system, entertainment system, etc.) before optimization. Specifically, the initial application corresponding to the above-mentioned target vehicle is usually built based on the AUTOSAR CP framework, which provides a standardized and modular software architecture for the automotive industry, aiming to improve the portability and reusability of ECU applications. In addition, the above-mentioned initial application includes multiple modules and protocol stacks designed in accordance with the AUTOSAR CP standard. These modules and protocol stacks cover various functions required by automotive electronic systems, such as communication, diagnosis, storage, etc., to ensure that the vehicle can perform complex control and management tasks.

[0039] Step S12, analyzing and processing the initial application to obtain a module to be optimized;

[0040] These modules are identified through in-depth analysis of the target vehicle's initial application program as having potential for improvement in terms of functionality, resource consumption, or performance efficiency. These modules may suffer from issues such as high memory usage, slow processing speeds, or low stability in specific scenarios due to design redundancy, improper resource management, or inefficient algorithms.

[0041] For example, the initial application can be analyzed and processed through code review, performance evaluation, requirements analysis, and compatibility checking to identify modules to be optimized. Specifically, manual or automated code review can be used to identify modules with redundant code as modules to be optimized. Performance analysis tools can also be used to measure the resource consumption and response time of modules in the actual operating environment, identifying modules with high resource utilization and slow response speed as modules to be optimized.

[0042] Step S13, adjusting the module to be optimized using the target dependency library to obtain the target application;

[0043] The target application is an optimized version of the original application, created by adjusting the modules to be optimized using the target dependency library. While maintaining the integrity of its original functionality, the target application is designed to operate more efficiently, stably, and resource-efficiently, providing users with a superior driving experience while also reducing development and maintenance costs for manufacturers and enhancing product competitiveness.

[0044] Step S14: controlling the target vehicle to perform the vehicle control task based on the target application.

[0045] The above-mentioned vehicle control tasks cover the entire life cycle from vehicle startup to driving and then to parking, including but not limited to power system management, body control, driving assistance functions, infotainment services, environmental perception and decision-making, vehicle network communication coordination and fault diagnosis.

[0046] For example, taking the vehicle body control task as an example, since the target application integrates the timer management and hash mapping table functions in the target dependency library, it can accurately control vehicle body components such as door locks, windows, and lights in a short period of time, improve the speed and accuracy of operation response, and ensure that when the driver or passenger issues a command, various body control functions can respond quickly without going through complex initialization processes or lengthy data search time. Specifically, the timer management function can ensure that vehicle body control tasks such as door locks and window lifts can be executed at the preset precise time and frequency. For example, when the driver presses the unlock button on the remote control key, the target application can immediately trigger the timer to control the door locks to open with millisecond accuracy, without waiting for additional initialization time, thereby improving the user experience.

[0047] Hash maps, on the other hand, provide a fast path for data retrieval in body control tasks. In body control scenarios, each vehicle component (such as windows, lights, and wipers) has unique control parameters and status identifiers. By storing and managing these parameters and identifiers in a hash map, the target application can instantly locate the correct vehicle component information upon receiving a control command, eliminating the need to traverse the entire data structure. This reduces operational latency and improves operational fluidity.

[0048] Based on the above steps S11 to S14, by obtaining the target dependency library and the initial application corresponding to the target vehicle, and analyzing and processing the initial application, the module to be optimized is obtained, and then the target dependency library is used to adjust the module to be optimized to obtain the target application. Finally, based on the target application, the target vehicle is controlled to perform vehicle control tasks, thereby achieving the purpose of lightweighting vehicle applications, reducing memory usage and increasing code reuse rate, thereby achieving the technical effect of improving resource utilization and simplifying maintenance processes, and thus solving the technical problems of low resource utilization and high maintenance difficulty in the vehicle application adjustment method provided in the relevant technology.

[0049] The following further introduces the vehicle application adjustment method in the embodiment of the present invention.

[0050] Optionally, in step S11, obtaining a target dependency library includes:

[0051] Step S111, obtaining a basic dependency library, wherein the basic dependency library includes standardized application components, and the standardized application components are used to provide basic software services for the target vehicle;

[0052] Step S112, splitting the basic dependency library to obtain multiple functional modules;

[0053] Step S113: reconstruct multiple functional modules to obtain a target dependency library.

[0054] Figure 2 is a schematic diagram of a basic dependency library according to one embodiment of the present invention, such as Figure 2 As shown, the basic dependency library includes the application layer (APP), the runtime environment layer (RTE), the operating system layer (OS) and the microcontroller abstraction layer (MCAL).

[0055] Specifically, the app resides at the highest level of the underlying dependency library, directly addressing user or business needs. It is responsible for implementing specific functional logic and services and is the core area of ​​the application system that handles business rules, user interface logic, and data conversion. Furthermore, the app can utilize hardware resources such as the processor, memory, and communication interfaces within the end-to-end workstation to perform computations and logic processing.

[0056] The RTE layer, located below the app, is the middle layer of the basic dependency library and is responsible for scheduling and managing communications between various layers. This includes the diagnostic module, memory management module, communication module, input / output hardware abstraction layer (IOHWABS), system library (SYSLIB), and configuration data description (CDD). The communication module includes the controller area network (CAN), local interconnect network (LIN), communication protocols (such as the FlexRay communication protocol), and Ethernet.

[0057] The OS is responsible for managing hardware resources and the software operating environment, and providing necessary services and interfaces for upper-layer software, including system service modules and the Extended Communication Protocol (XCP).

[0058] MCAL sits between the OS and the hardware, providing a hardware abstraction interface that allows the OS and apps to be independent of the specific microcontroller hardware. Specifically, MCAL includes the system driver (SYSDRIVER), memory driver (MEM DRIVER), communication driver (COMMUNICATION DRIVER), and input / output driver (I / O DRIVER).

[0059] For example, the base dependency library can be split into multiple functional modules, each responsible for a specific task. For example, a memory management module, a timer management module, a data structure module, and so on can be separated. During the segmentation process, it is necessary to ensure that the dependencies between the modules are minimized. Modules should be as independent as possible to facilitate independent testing and maintenance. For example, a memory management module should not depend on a timer module, and vice versa.

[0060] Based on the above steps S111 to S113, by obtaining the basic dependency library and splitting the basic dependency library to obtain multiple functional modules, and then reconstructing the multiple functional modules to obtain the target dependency library, code redundancy can be reduced, functional modularization can be achieved, and resource utilization can be improved.

[0061] Optionally, in step S113, multiple functional modules are reconstructed to obtain a target dependency library, including:

[0062] Step S1131, reconstructing the functions of multiple functional modules to obtain a target functional module;

[0063] Step S1132: perform interface standardization processing on the target functional module to obtain a target dependency library.

[0064] The above-mentioned interface standardization process mainly includes two aspects: one is to standardize the interface definition to ensure that the interaction between all modules follows a unified rule and format, thereby improving the interchangeability of modules and the overall consistency of the system; the other is to write detailed interface documents, clearly describing the functions, parameters, return values ​​and possible error handling mechanisms of each interface, providing clear guidance for developers, facilitating the correct calling of modules and subsequent maintenance of the system.

[0065] For example, when reconstructing the functions of the memory management module, we can first build a highly flexible memory pool management system that can support a variety of memory block size allocations and have dynamic scaling capabilities to seamlessly adapt to resource demand fluctuations in different scenarios. Subsequently, we can introduce a memory block allocation and recycling mechanism to ensure that memory resources can be quickly allocated. At the same time, we can avoid the accumulation of memory fragments through preventive and immediate fragmentation management strategies, ensuring that even under the harsh conditions of multi-threaded concurrent access, we can guarantee the efficiency and consistency of memory operations. Finally, we can introduce an automatic defragmentation mechanism to reduce the proportion of memory fragmentation through periodic memory block integration, thereby improving the overall utilization efficiency of memory space.

[0066] Furthermore, block transfers can be used for memory copying, leveraging the parallel processing capabilities of modern processors to accelerate memory zeroing operations. Compared to byte-by-byte copying, block transfers can move large amounts of data in a shorter timeframe, significantly reducing operation time. Memory alignment mechanisms can also be built into the memory management module to eliminate the performance overhead caused by unaligned accesses.

[0067] For example, when reconfiguring the function of the timer management module, first, a general timer management system is designed and developed to ensure that it can support various types of timers, such as periodic timers, single timers, and countdown timers, so as to meet the time management needs of the system in different scenarios. For scenarios that require high real-time performance, the timing accuracy can be further optimized by cooperating with software timers and hardware timers to ensure that the timing signal is accurate. Secondly, in terms of timer task management, the functional reconstruction module must have the ability to add, delete, pause, and resume timer tasks, and introduce a task priority management mechanism to ensure that critical tasks can be executed first when the system processes multiple tasks in parallel. Furthermore, in order to optimize time event scheduling, an efficient time event queue should be implemented to support fast event insertion and deletion operations to ensure real-time processing of events. Even under high load conditions, the time slice scheduling strategy can be dynamically adjusted to ensure that timer events are executed within the expected time slice, adapting to changes in system load while maintaining stable system operation.

[0068] For example, when reconstructing the functions of the data structure management module, common data structures such as circular queues, bidirectional linked lists, and hash maps can be introduced into the data structure management module. The above data structures can be directly called by various modules in the system to avoid repeated implementation.

[0069] For example, a general-purpose circular queue data structure with automatic expansion can be implemented to support the storage of different data types to adapt to different load requirements. At the same time, the queue's read and write operations are optimized to ensure that the queue's operational complexity remains at O(1) to improve response speed. In addition, for queue operations in a concurrent environment, a lock-free design can be designed to improve response speed.

[0070] For example, a doubly linked list data structure can be implemented to support efficient node insertion, deletion, and search operations. Linked list nodes should have self-management capabilities to simplify the operational logic of the linked list. Furthermore, the memory management of the doubly linked list can be integrated with the memory management module of the underlying dependency library to automatically manage memory allocation and deallocation for linked list nodes, reducing memory fragmentation.

[0071] For example, a general hash table structure can be implemented to support fast lookup, insertion, and deletion operations. The hash table should support dynamic expansion and contraction to accommodate varying data sizes. Furthermore, conflict resolution mechanisms, such as chain addressing or open addressing, can be designed to ensure that the hash table maintains good performance even under high loads.

[0072] In addition, in certain cases, linked lists and queues can be used in combination. For example, the nodes of a circular queue can be managed using a doubly linked list to provide a more flexible data operation method.

[0073] Illustratively, based on the above functional reconstruction operation, a target functional module can be obtained. Further, the interface standardization processing can be performed on the target functional module to obtain a target dependency library.

[0074] Based on the above steps S1131 to S1132, by functionally reconstructing multiple functional modules, a target functional module is obtained, and then the interface of the target functional module is standardized to obtain a target dependency library, which can eliminate redundant code and unnecessary functions, reduce the occupancy of memory and other system resources, and improve resource utilization.

[0075] Optionally, in step S12, the initial application is analyzed and processed to obtain a module to be optimized, including:

[0076] Step S121, obtaining performance indicators corresponding to the initial application, wherein the performance indicators include memory usage and response time corresponding to the initial application;

[0077] Step S122 : In response to the memory usage being greater than a preset usage threshold and the response time being greater than a preset time threshold, determining that the functional module corresponding to the current initial application is a module to be optimized.

[0078] The modules to be optimized include but are not limited to the diagnosis module, communication module, system service module and storage module in the initial application program.

[0079] For example, assuming that the preset occupancy threshold corresponding to the timer management module is 10MB and the preset time threshold is 250ms, when it is detected that the memory occupancy corresponding to the timer management module is greater than 10MB and the response time is greater than 250ms, the timer management module can be determined as a module to be optimized.

[0080] Based on the above steps S121 to S122, through performance testing and threshold monitoring mechanisms, functional modules that exceed preset thresholds can be promptly identified as modules to be optimized, thereby avoiding performance bottlenecks and improving system stability.

[0081] Optionally, in step S13, the module to be optimized is adjusted using the target dependency library to obtain a target application, including:

[0082] Step S131, determining the target functional module corresponding to the module to be optimized based on the target dependency library;

[0083] Step S132: Using the target functional module, the module to be optimized is adjusted to obtain a target application.

[0084] The above-mentioned target functional modules include but are not limited to a memory management module, a timer management module, a data structure management module and a code management module after functional reconstruction and interface standardization.

[0085] The memory management module adjusts the memory allocation and reclamation strategies in the modules being optimized. By introducing memory pool technology, it reduces the overhead of dynamic memory allocation, reduces memory fragmentation, and thus improves overall memory utilization. Furthermore, the memory management module provides standardized interfaces for memory operations, such as memory copy, clear, and alignment functions, to achieve efficient memory operations.

[0086] The timer management module is used to optimize the scheduling management of time and events. By providing different types of timers (such as periodic, single-trigger and countdown timers) and high-precision time event scheduling strategies, it ensures that time-sensitive tasks in the module to be optimized can be executed in a timely and accurate manner, thereby improving the real-time performance and stability of the system.

[0087] The data structure management module provides a series of efficient data structure implementations, such as circular queues, doubly linked lists, and hash maps, to replace inefficient data organization methods that may exist in the original system. These data structures are designed with full consideration of memory usage and access efficiency, making them particularly suitable for high-concurrency and large-scale data processing scenarios. They can effectively reduce data operation latency and improve response speed.

[0088] The Code Management module streamlines and refactors code. By modularizing the core functionality of system service modules and removing redundant code, it not only reduces application size but also enhances code readability and maintainability. The Code Management module also provides code optimization suggestions to help developers better understand and improve application logic, ensuring application quality while improving execution efficiency.

[0089] For example, the communication module in the original application often encounters problems such as data transmission delays and buffer overflows in high-concurrency communication scenarios. Therefore, if the program to be optimized is the communication module, its data structure and memory management adjustments are required. The corresponding target functional modules are the data structure management module and the memory management module.

[0090] For example, the diagnostic module in the original application often suffers from slow response and excessive memory usage when processing a large number of diagnostic requests. Therefore, if the module to be optimized is the diagnostic module, adjustments to its timer management, memory management, and data structure are required. The corresponding target functional modules are the timer management module, the data structure management module, and the memory management module.

[0091] Based on the above steps S131 to S132, by introducing target functional modules such as optimized memory management, timer management, data structure management and code management, memory consumption can be reduced, memory utilization efficiency can be improved, and the occupancy of CPU and storage resources can be reduced, so that the application can run more efficiently on limited hardware resources.

[0092] Optionally, the target functional module includes: a memory management module, a timer management module, a data structure management module, and a code management module. In step S132, the target functional module is used to adjust the module to be optimized to obtain a target application, including:

[0093] Step S1321, using the memory management module to adjust the memory management mechanism corresponding to the module to be optimized, to obtain a memory management application;

[0094] Step S1322: Using the timer management module, adjust the timer type corresponding to the module to be optimized to obtain a timer management application, where the timer types include periodic timer, single timer, and countdown timer.

[0095] Step S1323: Using the data structure management module to adjust the data structure type of the module to be optimized, wherein the data structure type includes at least one of the following: a circular queue, a doubly linked list, and a hash map;

[0096] Step S1324: Using the code management module to perform code management adjustments on the module to be optimized, thereby obtaining a code management application program, wherein the code management module is used to delete duplicate codes in the module to be optimized;

[0097] Step S1325 , merging the memory management application, the timer management application, the data structure management application, and the code management application to obtain a target application.

[0098] These periodic timers are primarily used for tasks that require regular execution, such as periodic vehicle status monitoring and system heartbeat detection. By setting a fixed period, periodic timers ensure stable and continuous execution of related tasks, avoiding the additional overhead of frequent checks and thus improving response speed.

[0099] The one-shot timer is used to execute a one-time scheduled task, such as starting a vehicle warm-up at a specific time or performing a diagnostic check. Unlike periodic timers, a one-shot timer automatically stops after completing its task, eliminating the need for continuous execution and reducing unnecessary resource consumption.

[0100] The countdown timer described above counts down to a specific time, triggering a corresponding action until the time expires. This type of timer provides precise timing control and enhances the user experience.

[0101] The aforementioned circular queue is a special linear data structure with a fixed size and internally loops. In ECUs, it's often used for message passing and task scheduling, particularly when processing continuous input and output operations. The advantage of a circular queue is that it avoids copying or moving elements when the queue is full, reducing memory overhead and data processing latency. For message queues in communication protocol stacks or data buffers in storage protocol stacks, using a circular queue can improve memory efficiency and data processing speed.

[0102] The aforementioned doubly linked list is a chain storage structure in which each node contains pointers to its predecessor and successor nodes. This makes it suitable for scenarios where element insertion and deletion are frequent, such as maintaining a dynamically changing list of diagnostic parameters in a diagnostic module. The advantage of a doubly linked list is that it can be traversed from front to back or back to front, providing more flexible data access. Furthermore, when inserting and deleting nodes, only the pointers to adjacent nodes need to be modified, without moving other nodes. This reduces memory operations and improves operational efficiency.

[0103] The hash map described above is an associative array-type data structure. By using a hash function to convert keys into indexes, it enables fast access to corresponding values. It is suitable for scenarios requiring efficient lookup, insertion, and deletion operations based on key values, such as managing connection status in communication modules and indexing data in storage modules. The advantage of a hash map is that it can achieve an average time complexity of approximately O(1), maintaining good performance even with very large amounts of data, thereby improving response speed and resource utilization efficiency.

[0104] For example, the diagnostic module is responsible for monitoring the operating status of the vehicle and providing diagnostic information when a fault occurs. As the functions of the vehicle increase, the amount and complexity of data that the diagnostic module needs to process are also increasing. The diagnostic module in the initial application often has problems with slow response and excessive memory usage when processing a large number of diagnostic requests. To address the above problems, the circular queue and Hash Map in the target dependency library can be integrated into the diagnostic module to replace the original queue and search algorithm. At the same time, the memory allocation and recovery logic in the diagnostic module can be replaced with the memory management module in the target dependency library, and a memory pool management mechanism can be used to reduce memory fragmentation. In addition, the timer management logic in the diagnostic module can be replaced with the timer management module in the basic dependency library to improve timing accuracy and task scheduling efficiency.

[0105] For example, the communication module is responsible for data transmission between various ECUs. With the advancement of vehicle intelligence and networking, the amount of data and communication frequency that the communication module needs to process have increased significantly. In the communication module of the initial application, problems such as data transmission delay and cache overflow often occur in high-concurrency communication scenarios. To address the above problems, the circular queue and bidirectional linked list functions in the target dependency library can be integrated into the communication module to optimize the management of message queues and connection lists. At the same time, the cache management logic in the communication module can be replaced with the memory pool management function in the target dependency library to improve cache utilization and hit rate. In addition, the data structure in the communication module can be replaced with the circular queue and Hash Map in the target dependency library to reduce data transmission delays.

[0106] For example, the storage module manages the vehicle's non-volatile memory (NVM), storing important data such as vehicle configuration information and driving data. As vehicle functionality increases, the amount of data the storage module must handle and the frequency of storage operations also increase. The storage module in the initial application often experiences storage delays and data loss during frequent read and write operations. To address these issues, the circular queue and doubly linked list in the target dependency library can be integrated into the storage module to optimize data buffer and storage queue management. Furthermore, the memory allocation logic in the storage module can be replaced with the memory pool management functionality in the target dependency library, reducing memory allocation and deallocation overhead. Furthermore, the data structures in the storage module can be replaced with the circular queue and hash map in the target dependency library, improving data storage and retrieval efficiency. Through memory pool management and data structure adjustments, the storage module significantly improves data reliability in abnormal situations such as power outages. Furthermore, the adjusted storage module has avoided memory leaks and data loss during long-term operation.

[0107] Furthermore, for different modules to be optimized, their corresponding target functional modules may be merged to obtain a target application corresponding to the current module to be optimized.

[0108] Based on the above steps S1321 to S1325, the target function module is used to adjust the module to be optimized, and the resulting target application can achieve efficient use of resources, improve system performance, enhance software stability and response speed, while simplifying the development and maintenance process and improving overall reliability and efficiency.
