Description

Technical Field

[0001] This application belongs to the field of VCU model development technology, and particularly relates to a VCU model development method, apparatus, electronic device and computer-readable storage medium. Background Technology

[0002] Currently, vehicle control unit (VCU) applications generally adopt a model-based development approach. Model development primarily falls into two categories: one treats all functional modules as a unified whole, with a single external input and output module; the other separates individual functional modules, such as power-on / off, torque, and gear shifting, with each module preprocessing its own input and output signals. Both approaches have the following problems:

[0003] During development, if the first model is adopted, all modules are integrated into a whole. This requires a dedicated integration engineer to perform the integration after each module is completed, and then code generation is performed after the integration is finished. In this model, code generation takes a long time, and if any module is modified, the integration engineer will have to perform integration and code generation again, which is time-consuming and labor-intensive.

[0004] If the second model is adopted, each functional module is developed independently, and the input and output modules are preprocessed uniformly in their respective modules. This reduces the time for model integration and code generation. However, the engineer in charge of the signal preprocessing module needs to process each signal and communicate with other modules on the signal processing methods, which increases the workload of the signal processing engineer.

[0005] Therefore, how to save time in model integration, code generation, and signal preprocessing, thereby improving model development efficiency and saving development costs, is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0049] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0050] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0051] Currently, vehicle control unit (VCU) applications generally adopt a model-based development approach. Model development primarily falls into two categories: one treats all functional modules as a unified whole, with a single external input and output module; the other separates individual functional modules, such as power-on / off, torque, and gear shifting, with each module preprocessing its own input and output signals. Both approaches have the following problems:

[0052] During development, if the first model is adopted, all modules are integrated into a whole. This requires a dedicated integration engineer to perform the integration after each module is completed, and then code generation is performed after the integration is finished. In this model, code generation takes a long time, and if any module is modified, the integration engineer will have to perform integration and code generation again, which is time-consuming and labor-intensive.

[0053] If the second model is adopted, each functional module is developed independently, and the input and output modules are preprocessed uniformly in their respective modules. This reduces the time for model integration and code generation. However, the engineer in charge of the signal preprocessing module needs to process each signal and communicate with other modules on the signal processing methods, which increases the workload of the signal processing engineer.

[0054] To address the problems of the prior art, embodiments of this application provide a VCU model development method, apparatus, electronic device, and computer-readable storage medium. The VCU model development method provided in this application embodiment will be described first below.

[0058] Multiple functional modules are obtained; these include the Input_Pre module for input signal preprocessing, the Total Quality Management (TQC)_Ctrol module, and the Output_Pre module for output signal preprocessing.

[0059] The SWC mode based on the Autosar architecture utilizes the Input_Pre module, TQC_Ctrol module, and Output_Pre module to build a TQC model.

[0060] In one embodiment, there are m input signals and n output signals; where m and n are both positive integers.

[0061] In one embodiment, the functional module further includes a power-on / off module, a torque module, and a gear processing module.

[0062] This application transforms the integrated model in the prior art into an SWC model based on the AUTSAR architecture. This design places the input and output of each functional module in its respective module for preprocessing. Specifically, compared to the prior art, this application eliminates the unified input preprocessing module and output preprocessing module, processing the input and output signals of each functional module within its own module.

[0063] S102. After receiving the input signal, each functional module preprocesses its respective input signal.

[0064] In one embodiment, after receiving the input signal, each functional module preprocesses its respective input signal, including: after receiving the input signal, the Input_Pre module preprocesses the input signal.

[0066] In one embodiment, processing the preprocessed input signal to obtain an output signal includes: processing the preprocessed input signal using the TQC_Ctrol module to obtain an output signal.

[0067] S104. Each functional module preprocesses its own output signal to obtain the preprocessed output signal.

[0068] In one embodiment, each functional module preprocesses its respective output signal to obtain a preprocessed output signal, including:

[0069] The Output_Pre module is used to preprocess the output signal to obtain the preprocessed output signal.

[0070] This VCU model development method is based on the SWC mode of the Autosar architecture software components. It uses multiple functional modules to build a vehicle controller VCU model. After receiving the input signal, each functional module preprocesses its own input signal. After processing the preprocessed input signal, the output signal is obtained. Each functional module preprocesses its own output signal to obtain the preprocessed output signal.

[0071] The VCU model development method is a distributed development model, which saves engineers time in the integration process and code generation compared to the integrated model, thus improving the efficiency of model development. Moreover, the model design eliminates the unified signal preprocessing process and decomposes it into various functional modules, saving development costs.
