The cost of automotive electronics and software accounts for an increasingly larger proportion of the overall vehicle cost. SOA (Service-Oriented Architecture) is a future trend in intelligent vehicle development. It leverages the different functional units decomposed from applications, connecting interfaces and protocols through these services. SOA, through hardware-software decoupling, strong scalability, and portability, accelerates convenient interaction between vehicles, people, and networks, creating a healthy automotive ecosystem and accelerating the increasing intelligence of vehicles. In the development of automotive software based on SOA architecture, the use of Simulink tools for model-based development is increasingly replacing manual code development.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Simulink is a visualization and simulation tool within MATLAB, developed by MathWorks. Service-Oriented Architecture (SOA) is a component model that breaks down an application into different functional units (called services) and connects them through defined interfaces and protocols. These decomposed units are called atomic services, which are microservices with independent functionality that can be deployed independently and used across multiple applications. These independent services can interact with other services to provide specific functionalities. By decomposing macro services into smaller components, atomic services make applications more flexible and scalable. The independence and reusability of atomic services make development easier and maintenance simpler. Furthermore, atomic services can be built using the latest technologies and tools, allowing applications to better adapt to change.

[0042] This invention is a development method for a headlight washer control component based on the Simulink tool and SOA architecture. It constructs the functionality of the headlight washer control component using Simulink and executes the functionality through SOA architecture. By treating sub-functional modules as atomic services and directly placing them into the runtime entity, it not only demonstrates the flexibility of SOA but also allows services to communicate through simple, precisely defined interfaces, avoiding involvement of underlying programming interfaces and communication models, thus enabling better and faster delivery of business value.

[0043] Figure 1 This is a schematic diagram illustrating a development method for a headlight washer control component based on Simulink and SOA architecture in an embodiment of the present invention. As shown in the figure, a development method for a headlight washer control component based on Simulink and SOA architecture includes:

[0044] S101. Establish the operating entity corresponding to the cleaning control component;

[0045] S102. Place the sub-functional modules as atomic services into the running entity;

[0046] S103. Based on the atomic service, determine the corresponding API interface;

[0047] S104. Place the signal input module and the signal output module into the running entity;

[0048] S105. Based on the operating entity, construct the cleaning control component.

[0049] Based on the Simulink environment, a headlight washer control module containing multiple sub-functions was created as a running entity. Event execution cycles were added to this entity. Sub-function modules were placed within the running entity as atomic services, and the service interfaces provided by these atomic services were determined according to API definitions. A signal input module was added to the running entity to periodically receive API interface requests from the sub-function modules. The corresponding atomic modules of the sub-function modules verified the API interface requests, executed the corresponding methods, and obtained the output results. A signal output module was added to the running entity to output the corresponding API interface output results, converting the output results into output signals, and sending them to the service gateway (the service gateway's role is unified access, traffic control, security protection, and business isolation) via Ethernet. The service gateway parsed the output signals, converted them into CAN messages, and sent them to the BCM (Body Controller). The BCM then controlled the implementation of the headlight washer function provided by the corresponding atomic service. After testing in the Simulink environment, the corresponding code for the headlight washer control component was generated and integrated into the vehicle's infotainment system to form a headlight washer control component based on Simulink and SOA architecture. The flowchart of the Ethernet signal transmission is shown below. Figure 2 As shown.

[0050] The CAN bus is one of the most widely used fieldbuses internationally. Designed for microcontroller communication in automotive environments, it facilitates information exchange between various electronic control units (ECUs) to form an automotive electronic control network. Examples include engine management systems, transmission controllers, instrument clusters, and electronic backbone systems, all of which embed CAN control devices. CAN messages refer to sensor information parsed from the CAN bus. Exemplarily, they include four different message types: data frames, remote frames, overload frames, and error frames. A message consists of an 11-bit or 29-bit identifier, a control field, and up to 8 bytes.

[0051] The sub-functional modules of the aforementioned headlight washer control component, namely atomic services, include: power service, outside temperature service, washer fluid service, headlight service, etc., as well as the corresponding service methods provided by the atomic services.

[0052] The API interface signals received by the above signal input module include: voltage status signal, outside temperature signal, washer fluid level signal, and headlight washer switch indicator light.

[0053] The API interface signals output by the above signal output module include: cleaning motor control signal, cleaning nozzle heating signal, and cleaning liquid level low alarm signal.

[0054] For example, the above-mentioned cleaning fluid service includes a cleaning fluid level alarm service. The technical solution of the present invention will be further illustrated below using the cleaning fluid level alarm service as an example:

[0055] The signal input module periodically receives the cleaning fluid level signal. The cleaning fluid level alarm service verifies the signal. When the input value of the cleaning fluid level is lower than the warning value, the alarm method in the service is executed, generating a low cleaning fluid level alarm signal. The signal output module transmits this alarm signal via Ethernet to a serviceless gateway for parsing. The gateway converts the alarm signal into a CAN signal and transmits it to the BCM (Body Domain Controller). The BCM then controls the HMI (Human Machine Interface) to issue a low cleaning fluid level alarm. The cleaning fluid level alarm service verifies the cleaning fluid level signal. When the input value of the cleaning fluid level signal is greater than or equal to the warning value, the alarm method in the cleaning fluid level alarm service is executed, resulting in a cleaning fluid level alarm signal. The signal output module transmits the cleaning fluid level alarm signal via Ethernet to the service gateway for parsing. The cleaning fluid level alarm signal is converted into a CAN signal and transmitted to the BCM (Body Domain Controller). The BCM then controls the HMI to clear the low cleaning fluid level alarm. A flowchart of the cleaning fluid level alarm service is shown below. Figure 3 As shown.

[0056] In summary, the technical solutions in the embodiments of this application have at least the following technical effects or advantages:

[0057] This invention relates to a headlight washer control component designed based on Simulink and SOA architecture. The steps are simple, the module structure is clear, and it only provides API interface interaction to the outside world, which can easily establish connections with other modules. It decouples the headlight washer control component in the vehicle system from hardware and software, makes the internal and external interface interaction of the vehicle system clear, improves the intelligence of the car, and realizes the intelligent cleaning function of the car headlights.

[0061] Signal input module 402 is used to receive API interface requests corresponding to the sub-functional modules;

[0062] The signal output module 403 is used to output the output signal of the atomic service corresponding to the request of the API interface;

[0063] The service gateway module 404 is used to convert the output signal into a CAN signal and transmit it to the body controller.

[0064] For example, the headlight washer control component also includes a timer module for the signal input module to periodically receive API interface requests corresponding to the sub-functional modules.

[0065] For example, the atomic services in the headlight washer control component include: power service, outside temperature service, washer fluid service, and headlight service.
