In the present disclosure, a computer-readable storage medium may be any tangible medium containing or storing a program that may be used by or in conjunction with an instruction execution system, apparatus, or device.

[0070] In order to enable those skilled in the art to better understand the present invention, the principle of the present invention is described as follows in conjunction with the accompanying drawings:

[0071] The present invention aims to break away from the original architecture of the washing control function and improve the intelligence of the car. It provides a method for developing a wiper washing control component based on the Simulink tool and the SOA architecture. The method for developing a functional software component using Simulink is as follows:

[0072] A washing control module including multiple sub-functions is regarded as a running entity as a whole, and a running event time period is added to the running entity;

[0073] Put the input signal processing module and sub-function modules of the washing control module into the running entity;

[0074] Determine the input and output signals of the running entity; define the input and output signal interfaces of the running entity as API interfaces according to the standards, and define the atomic services of the washing control module.

[0075] Subsequently, the input signal processing module and the sub-function module of the washing control module are placed in the running entity, wherein the input signal processing module at least includes a power state signal, an outside temperature signal, a washing liquid level signal, and a wiper washing switch signal;

[0076] After receiving the input signal, the output signal is transmitted to the corresponding sub-function according to different signals, wherein the output signal at least includes a washing motor control signal, a wiper nozzle heating signal, and a washing liquid level low alarm signal;

[0077] The sub-function sends messages via Ethernet to exchange information.

[0078] The service-oriented gateway connects to the API interface from the sub-function, where the service-oriented gateway parses the atomic service API information, assembles it into CAN messages and sends it to the body domain controller (BCM), and then uses the BCM to control the corresponding wiper and washing functions. The signal input and output of the washing control module are as follows Figure 4 shown.

[0079] The method of functional service based on SOA architecture can extract the corresponding functions of washing control into atomic services, forming different independent units, and no underlying operations are required in the subsequent modification process. A series of composite services can be directly composed through different atomic services, thereby realizing functional logic judgment.

[0080] The core value of the present invention lies in the simplicity of the designed software components and the clear module structure. It can easily establish software components in the tool chain, improve development efficiency, facilitate the addition of module functions, and establish connections with other modules after subsequent import into the tool chain.

[0081] The present invention is a method for developing a windshield wiper and washing control component based on Simulink tools and SOA architecture. The invention constructs the function of the windshield wiper and washing control component through Simulink and executes the function through SOA architecture. Figure 5 The present invention provides a flow chart of a development method of windshield wiper and washing control software based on Simulink tool and SOA architecture.

[0082] like Figure 5As shown, first, the washing control module containing multiple sub-functions is taken as a running entity as a whole, and a running event time period is added to the running entity. Next, the input signal processing module and the corresponding sub-function module are placed in the running entity, and the input signal processing module is set. The input signal includes the power status signal, the outside temperature signal, the washing liquid level signal, and the wiper washing switch signal. All input signals are defined according to the API interface. Next, the output signal processing module is set. The output signal includes the washing motor control signal, the wiper nozzle heating signal, and the washing liquid level low alarm signal. All signals are defined according to the API interface. After testing, the code of the relevant functions is generated in Simulink.

[0083] After receiving the corresponding signal, the sub-function sends the corresponding message through Ethernet to interact with each other. The service-oriented gateway connects to the API interface from the sub-function, parses the atomic service API information, assembles it into a CAN message and sends it to the body domain controller (BCM), and then uses the BCM to control the corresponding wiper and washing function. The specific process of SOA is as follows Figure 6 shown.

[0084] Taking the washing liquid level alarm function as an example, the input signal module receives the washing liquid level signal at regular intervals and inputs the signal into the washing liquid alarm module, which is verified by this submodule. When the washing liquid level input value is lower than the warning value, the washing liquid alarm module calls the alarm method in the washing liquid level low alarm service, and the service is transmitted to the service gateway via Ethernet for analysis. After the service gateway parses the service, the alarm method is converted into a CAN signal and transmitted to the body domain controller (BCM). The BCM controls the HMI to alarm the low washing liquid level. When the washing liquid level input value is greater than or equal to the warning value, the washing liquid alarm module calls the alarm cancellation method in the washing liquid level low alarm service, and the service is transmitted to the service gateway via Ethernet for analysis. After the service gateway parses the service, the alarm cancellation method is converted into a CAN signal and transmitted to the body domain controller (BCM), and the HMI cancels the low washing liquid level alarm. The general process of the washing liquid level alarm is as follows: Figure 7 shown.

[0085] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
