[0023] The following describes the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art will readily appreciate the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the various details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0024] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be changed arbitrarily, and the component layout may also be more complex.

[0025] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it will be apparent to those skilled in the art that the embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring the embodiments of the present invention.

[0026] See also Figure 1 , Figure 1This is a flowchart illustrating a method for automatically generating an input interface model based on Matlab, as illustrated in an exemplary embodiment of the present application. This method can be implemented using other implementation environments known to those skilled in the art. This method can be applied to the automated development of controller application layer interface software. By maintaining the interface signal's name, data type, and other attributes in a specific format in an Excel spreadsheet and establishing a specific mapping relationship, application layer input and output interface models can be automatically generated. Generating a calibratable interface decouples the application layer from the underlying interface, facilitating troubleshooting of interface issues.

[0027] like Figure 1 As shown, in an exemplary embodiment, the method for automatically generating an input interface model based on Matlab includes at least steps S101 to S104, which are described in detail as follows:

[0028] Step S101, obtaining a target Excel table based on Matlab.

[0029] Among them, the target Excel table includes multiple interface signal information of the vehicle's underlying software.

[0030] The target Excel table pre-stores the interface signal's name, data type, and other attributes, maintained in a preset format, as interface signal information. When adding a signal, the method provided in this embodiment only requires maintaining the new signal in the target Excel table, eliminating the need for developers to manually add signals and avoiding human error.

[0031] This step can be achieved by interacting with Excel through Matlab language to filter and extract information from Excel.

[0032] The target Excel table can adapt to multiple projects by shielding the interface to improve the portability of the functional module software.

[0033] Step S102: extract target signal information from the plurality of interface signal information in the target Excel table.

[0034] In one embodiment, target signal information is extracted from multiple interface signal information in a target Excel table, including: obtaining a signal selection instruction, the signal selection instruction including a target input signal identifier and a target output signal identifier; reading all information in the target Excel table into a preset Cell array; extracting input signal information from the preset Cell array based on the target input signal identifier, and extracting output signal information from the preset Cell array based on the target output signal identifier, the target signal information including input signal information and output signal information.

[0035] Step S103: calibrate the target signal information.

[0036] In one embodiment, the target signal information is calibrated, including: extracting the output signal name of the output signal information, where the output signal name is obtained based on the interface signal information; adding a prefix string and a suffix string to the output signal name to generate a calibration switch and a calibration amount of the output signal; setting the position parameters of each input signal information, and connecting them according to the corresponding relationship.

[0037] In one embodiment, target signal information is calibrated, including: if there are at least two input signal information with the same signal name, combining the same multiple input signal information into a matrix, generating an Inport module for the input signal information located at the front of the target Excel table based on the position of each input signal information in the target Excel table, and generating other input signal information in the matrix as Goto modules and corresponding From modules; if an input signal information is not in any matrix, adding a calibration switch, a calibration amount and a selection module to the input signal information; setting the position parameters of each input signal information, and connecting them according to the corresponding relationship.

[0038] Among them, the calibration switch can be used for subsequent testing. If the signal needs to be tested, turn on the calibration switch. At this time, based on whether the application layer software receives the signal, it can be judged whether the underlying software on the current signal transmission path has not been successfully uploaded or there is a problem with the intermediate forwarding pipeline.

[0039] Step S104 : generating a target structure to be sent to the vehicle application layer based on the calibrated target signal information, so as to automatically generate an input interface model.

[0040] In one embodiment, before generating a target structure to be sent to the vehicle application layer based on the calibrated target signal information, the method further includes: determining whether a constant is required as input; if a constant is required as input, extracting the constant signal name obtained from the target Excel table, generating a constant module, and completing the connection; if a constant is not required as input, generating a From module, and naming the From module as the signal name of the corresponding input signal information.

[0041] One condition for determining whether a constant is needed as input is to determine whether a frame loss phenomenon occurs and whether a replacement value (constant) needs to be replaced. If necessary, the constant is used for replacement.

[0042] In one embodiment, before generating a target structure to be sent to the vehicle application layer based on the calibrated target signal information, the method further includes: if the calibrated target signal information is a CAN signal, generating an Inport module as a port, and then generating a Goto module to connect; if the calibrated target signal information is a non-CAN signal, combining them in the form of a structure.

[0043] In one embodiment, a target structure to be sent to the vehicle application layer is generated based on the calibrated target signal information, including: combining the calibrated target signal information according to the structure signals in the target Excel table to obtain the target structure.

[0044] The method provided in the above embodiment screens the interface signals (extracts target signal information), classifies them, and generates a model based on the signal summary table, that is, the target Excel table.

[0045] Optionally, one way to generate the interface signal information in the target Excel table may be to split the structure of the underlying software into single signals, and write the split single signals and the CAN signal of the underlying software as interface signal information into the target Excel table.

[0046] See also Figure 2 , Figure 2 This is the framework of the input model software shown in an exemplary embodiment of this application. Figure 2 As shown, the multiple structured signals of the vehicle's underlying software, such as the hardwire and EEPROM, are split into multiple individual signals. CAN signals remain CAN signals, and calibration constants, individual signals, and CAN signals are input into the input base model. The input signals are processed differently by determining whether there are replacement values ​​after frame loss. If there are replacement values ​​after frame loss, meaning a constant is required as input, the lost frame is converted and replaced with the constant and output. If there are no replacement values ​​after frame loss, the calibration process proceeds normally, with the calibration switch (calibration Sw) and calibration value (calibration Value) set via the conversion module (switch). The output signals are combined into a structure to obtain the target structure, which is then input into the application layer software.

[0047] The following is an illustrative example of the process of automatically generating an input interface model based on Matlab. Figure 3 , Figure 3 FIG. 1 is a specific flow chart of a method for automatically generating an input interface model based on Matlab, as shown in an exemplary embodiment of the present application. Figure 3 As shown, it shows the process of obtaining information from Excel by using Matlab language and then operating Matlab to automatically establish an input interface model.

[0048] Get Excel information and read all the information into a Cell array, that is, Figure 3 The Excel spreadsheet information is obtained as a Cell type array. Generate the outer subsystem and inner subsystem, and set the position and size of the subsystem. Use the For loop to extract the required input and output signals from the Cell array, and based on the output signal name, generate the calibration switch and calibration value name by adding prefixes and suffixes. Figure 3 ) for the next step. Find the repeated input signals and their locations, combining them into a matrix. Determine whether the input signal to be added is a repeated signal. Compare each input signal obtained from Excel with the matrix of the repeated signal. If it is included in the matrix of the repeated signal, generate an Inport module for the signal at the first position of the repeated signal, and generate Goto modules and corresponding From modules for the remaining positions. Set the corresponding position parameters and connect them according to the corresponding relationship. If the input signal is not in the matrix of the repeated signal, generate the corresponding constant module and select the module. Finally, complete the connection according to the corresponding relationship.

[0049] Generate the input of the innermost subsystem. First, determine whether constants are required as input. If not, generate From and name it as the corresponding input signal. If required, extract the constant signal name obtained from Excel, generate the corresponding constant module, and complete the connection. Filter out CAN signals, generate Inport as the port, and then generate Goto to connect. Filter out all non-CAN signals and combine them in the form of a structure. Filter out the signals corresponding to the output structure and generate the corresponding structure signals. That is, the output signals are combined according to the structure signals in the table and merged into the corresponding structure (target structure).

[0050] The method provided by the above embodiment is to interact with Excel through the Matlab language, filter and extract information in Excel, filter according to specific characters in the table, extract input and output signals, and use them as calibration quantities by adding prefixes and suffixes. Through screening, the corresponding signals are combined into structure signals to generate corresponding structure arrays. The input and output signals that need alternative values ​​are screened out, and the corresponding alternative values ​​are output after the frame is lost. In the Simulink environment, modules are added, module positions and paths are set, parameters (size, color, and data type, etc.) are set, and wiring is automatically performed to finally generate the required Simulink model.

[0051] The method provided in the above embodiment can automatically generate the application layer input and output interface model by maintaining the name, data type and other attributes of the interface signal in a specific format in an EXCEL table, establishing a specific mapping relationship. By generating a calibratable interface, the application layer and the underlying interface can be decoupled, making it easier to troubleshoot interface problems. When the corresponding signal frame communication is lost, an alternative value is generated as input. This facilitates the development of platform-based interface software, and multiple projects can be adapted by shielding the interface in an Excel table, ensuring the portability of the functional module software, greatly increasing the efficiency of software development, reducing errors caused by human modification, and ensuring the quality of software development.
