or searching the module in the software architecture corresponding to the mutually matched signal to be associated, and connecting the modules in the software architecture to obtain the interactive link.
It should be noted that, regarding the connection process provided in this embodiment, character retrieval may be performed on the module name information in the module information to obtain a plurality of modules to be associated, of which the module name information is matched with each other, and the modules to be associated are connected to obtain an interaction link for signal interaction;

and if the middleware module detects a trigger signal for triggering the module in the software architecture to run, connecting a module for sending the trigger signal with a module for receiving the trigger signal according to the trigger signal to obtain the interactive link.
It should be noted that, regarding the connection process provided in this embodiment, connection may be performed according to a trigger signal of some modules in a software architecture, specifically, when a module trigger signal occurs, the trigger signal generally carries information of a signal sending end and information of a signal receiving end, which is a signal interaction flow direction, so that a module that sends the trigger signal and a module that receives the trigger signal may be connected by the trigger signal to obtain an interaction link, so that a communication relationship between the sending end of the trigger signal and the receiving end of the trigger signal can be established for a certain time.
In one embodiment, the connecting, by the middleware module, the modules in the automobile architecture according to the module information and/or the signal information and according to a preset connecting rule to obtain an interactive link includes:
and if the middleware module needs to communicate with the module in the software architecture, connecting the middleware module with the module in the software architecture to obtain the interactive link.
It can be understood that, because the middleware module plays a linking role in the software architecture, so that the modules in the software architecture can communicate with each other, when the middleware module is connected, the middleware module can be connected according to the call relationship of each module in the architecture to the middleware module, that is, the connection can be performed according to the actually used module of the middleware module.
In one embodiment, the middleware module acquires module information and signal information in the software architecture, and comprises:
the middleware module detects and judges that the type information of the acquired signal is a single signal or a structural body signal, wherein the single signal is used for communicating with the electronic control unit, and the structural body signal is used for communicating with the logic operation module;
if the type information of the signal is a single signal, performing type conversion on the signal through a middleware module to obtain a structure body signal which can be used by the logic operation module.
The single signal and the structure signal are types of signals, and the single signal is mainly used for communication with an electronic control unit, such as a Controller Area Network (CAN) signal, a Controller Area Network (CAN) signal with variable baud rate (CANFD), an ethernet signal, and the like. The structure body signal is mainly used for communication with the logic operation module, is signal data oriented to the operation process of an application program, is structural data formed by combining a batch of data generally, can be customized by a programmer, and is mainly in a form of packaging so that the data in the structure body has reusability.
Therefore, when a single signal transmitted by an automobile component such as an electronic control unit is received, the single signal can be converted into a structural body signal, so that data information carried by the single signal can be called by a module in the software architecture, and the software architecture can establish a communication relation with the specific automobile component.
In one embodiment, after obtaining the structure signal that can be used by the logic operation module, the method further includes:
and the logical operation module splits and recombines the structural body signal according to the identification information in the structural body signal to obtain a reordered structural body signal so as to prevent the structural body signal from being analyzed.
Wherein, the identification information refers to ID information in the signal, and the splitting and recombining process comprises: after the CAN signals are converted by the middleware module, the single signals with the same ID, such as the CAN signals, CAN be reordered according to different actual use modules of all the signals, so that the ordered signals are different from the ordered positions of the signals before being converted by the middleware module, the CAN signals CAN be distinguished from the signals used in the actual software module, and the signals are prevented from being analyzed and permeated.
Optionally, the signals converted by the middleware module are adjusted in signal name information and/or signal arrangement mode to be different from the signals before conversion.
In one embodiment, before the wiring the modules in the automobile architecture according to the preset wiring rule, the method further includes:
the middleware module compares the signal interaction types of the modules in the software architecture and judges whether the signal interaction types of the modules in the software architecture are matched or not;
if yes, the middleware module connects the modules in the software architecture according to the connection rule.
It should be noted that before the connection, some specification information of the modules needs to be subjected to matching check, for example, a signal interaction type, a signal output by each module in the software architecture needs to display that the signal interaction type is a single signal and/or a structural body signal, the connection of the modules matched with the signal interaction type can ensure that no signal interaction problem occurs, and meanwhile, the output signal of each module displays related signal information, which is more convenient for signal mapping with signals of other modules.
Optionally, in order to make the module association method in the above embodiment operate on the AutoSar, the output signal of each module should need to meet the interface requirement of the AutoSar specification.
In one embodiment, before the connecting the modules in the automobile architecture according to the preset connecting rule, the method further includes:
the logic operation module carries out logic modeling to obtain a logic operation model for executing logic operation;
performing code compiling on the software architecture according to the logical operation model to obtain an architecture file, wherein the architecture file records interface information of modules in the software architecture;
judging whether the interface information of the modules in the software architecture to be associated is matched or not;
and if so, connecting the modules in the software architecture matched with the interface information according to the module information and/or the signal information to obtain the interactive link.
Illustratively, in the logical operation process, ARXML (automotive architecture XML, automobile development architecture system extensible markup language) may be used as a carrier of a logical operation framework, which is a rule based on the AUTOSAR automobile open architecture system, and can enable a software architecture to have a more canonical format expression, and reduce the workload of tool implementation based on the XML specification.
Logic modeling is carried out in the framework carrier, and after the modeling is finished, code compiling is carried out based on AutoSar to obtain a corresponding framework file, such as a c \ h \ Arxml file, and interface information of the module is recorded in the framework file. It should be noted that the logic operation module may generate an independent architecture file according to the combination service that can be implemented by each logic operation sub-module.
After the architecture file is generated, the modules can be associated or the signals can be mapped according to the interface information recorded in the architecture file, so that the corresponding relation between the modules and the corresponding relation between the signals can be determined.
It should be noted that, when all modules in the frame carrier are connected, the function of the logical operation module completes association, i.e. completes mapping relationship, and an ARXML file may be output to determine the overall frame relationship.
It should be understood that, although the steps in the above-described flowcharts are shown in sequence as indicated by the arrows, the steps are not necessarily performed in sequence as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least a portion of the steps in the above-described flowcharts may include multiple sub-steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, and the order of performing the sub-steps or the stages is not necessarily sequential, but may be performed alternately or alternatingly with other steps or at least a portion of the sub-steps or stages of other steps.
