[0002] Currently, with the continuous advancement of vehicle intelligence, in-vehicle functions such as autonomous driving, V2X (vehicle-to-X) communication, and smart cockpits are becoming increasingly sophisticated, making the interaction between vehicle ECUs (Electronic Control Units) increasingly complex. To decouple these previously dispersed ECUs, vehicles have introduced Ethernet and SOA (Service-Oriented Architecture) to deploy ECUs in a layered software architecture, achieving modular and standardized ECU functionality for rapid response to vehicle needs. Furthermore, SOA enables communication via the DDS (Data Distribution Service) protocol, which features low latency, high reliability, and supports various QoS (Quality of Service) strategies, meeting the data transmission requirements in different scenarios.

[0003] However, since the DDS protocol is implemented using C++ as the development language, while the smart cockpit system is built on the Android language, it is impossible to implement the DDS protocol middleware layer in the smart cockpit using SOA services as the architecture.

[0024] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and sub-samples in the embodiments can be combined with each other.

[0025] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0026] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the invention. However, it will be apparent to those skilled in the art that embodiments of the 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 embodiments of the invention.

[0027] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this disclosure described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0028] Unless otherwise stated, the term "multiple" means two or more.

[0029] In this embodiment of the disclosure, the character " / " indicates that the objects before and after it are in an "or" relationship. For example, A / B means: A or B.

[0030] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0031] First, it should be noted that in some embodiments, the in-vehicle language used in the smart cockpit of the vehicle terminal is Android. Since the underlying layer of Android is based on the Linux system, Android can call dynamic library files (e.g., SO library files) under the Linux system.

[0032] In some embodiments, the intelligent cockpit in the vehicle terminal adopts a service-oriented architecture (SOA). The SOA architecture adopts the Proxy / Skeleton pattern, where the Proxy service represents a possible remote service (e.g., process, kernel, node, etc.) and is a localized instance of the client. The Skeleton service is the connection between the user-provided service implementation and the middleware transport structure. The server-side implementation class can be derived from the Skeleton service.

[0033] In some embodiments, the service-oriented architecture can integrate a data distribution service (DDS), wherein the data distribution service uses C++ as its service language and is configured with a service function library (DDS C++ library), which stores service functions built based on the C++ language, and the data distribution service can be invoked by calling the service functions.

[0034] In some embodiments, the native service interface includes the JNI (Java Native Interface) interface. The native service interface provides a solution for integrating native code such as C / C++, Android, JAVA, and assembly. This specification enables Java code running within the Java Virtual Machine to interoperate with other programming languages, including creating native methods, updating Java objects, calling Java methods, referencing Java classes, catching and throwing exceptions, etc. It also allows Java code to call programs and libraries written in C / C++ or assembly language. In particular, using C / C++ as the programming language and providing it as an SO library file for upper-level JAVA code to call can prevent JAVA from being decompiled, thereby ensuring the security of the application.

[0035] Combination Figure 1 As shown in the embodiments of this disclosure, a data distribution service invocation method is provided, including:

[0036] Step S101: Obtain the intelligent cockpit and the service function library and basic service information corresponding to the data distribution service;

[0037] The intelligent cockpit is equipped with an operating system based on the vehicle language, and the service function library stores service functions based on the service language.

[0038] Step S102: Compile the service function library code according to the vehicle language to obtain a dynamic library file for the vehicle language;

[0039] Among them, dynamic library files are used to encapsulate service functions;

[0040] Step S103: Fill in the basic service information into the preset code template to obtain the service code file;

[0041] Step S104: Establish a local service interface in the smart cockpit based on the service code file, and call the dynamic library file through the local service interface to enable the smart cockpit to call the data distribution service.

[0042] The data distribution service invocation method provided in this disclosure involves compiling the service function library into a dynamic library file using the vehicle-grade language, and generating a service code file using basic service information. This service code file then establishes a local service interface for calling the dynamic library file. Thus, even when the smart cockpit and the data distribution service use different code languages, the dynamic library file is called through the local service interface established in the smart cockpit, enabling smart cockpits using different languages ​​to invoke the data distribution service. This integrates the low latency and high reliability characteristics of the data distribution service, improving the transmission efficiency of the vehicle-grade smart cockpit.

[0043] Optionally, the service function library is compiled according to the vehicle language to obtain dynamic library files for the vehicle language, including: obtaining a compilation toolkit for the vehicle language; and using the compilation toolkit to compile the service function library to obtain dynamic library files corresponding to each processor architecture.

[0044] In some embodiments, the compilation toolkit includes the Android NDK (Native Development Kit) toolkit. The NDK is a means of implementing the JNI interface in the Android system, used to package C / C++ dynamic libraries and make calls based on the JNI interface.

[0045] In some embodiments, the DDS C++ library is compiled using the Android NDK toolkit to package service functions and generate SO library files corresponding to various CPU architectures, including ARM, x86, etc.

[0046] Optionally, basic service information can be obtained through the following methods: establishing a service information template corresponding to the data distribution service; receiving template data input by the user into the service information template, and determining the service information template with the template data as a service information file; extracting information from the service information file according to a preset extraction script to obtain information string data, wherein the information string data carries the basic service information corresponding to the data distribution service.

[0047] In some embodiments, the service information template is created based on an Excel spreadsheet. The service information template includes the service name, service domain, service code, service package name, and service interface information. The service interface information includes the service interface method name, interface method parameters, QoS information, Topic information, and interface method type. The interface method parameters include input parameters, output parameters, and input / output parameter types, and the interface method type includes Method, Event, Field, etc.

[0048] In some embodiments, information is extracted from the service information file using a Python script to obtain information string data.

[0049] Optionally, the basic service information is filled into a preset code template to obtain a service code file, including: the preset code template includes a base class code template and an interface code template; the basic service information is filled into a framework code template to obtain a base class code file for the service language, and the basic service information is filled into an interface code template to obtain an interface code file for the vehicle language.

[0050] Optionally, by filling in the basic service information into the base class code template (DDS-SOA middleware code template), a base class code file (e.g., a Class file) is obtained. The base class code file includes an SOA Proxy C++ code file and a SOASkeleton C++ code file. The base class code file is used to create a service-oriented framework, register services, and set interface method types.

[0051] Optionally, by filling in the basic service information into the interface code template (DDS-JNI intermediate layer code template), interface code files (JNI files) and JAVA files are obtained. The interface code files include SOA Proxy JNI files and SOASkeleton JNI code files, wherein the interface code files are used to encapsulate the JNI interface.

[0052] Optionally, a local service interface is established in the smart cockpit based on the service code file, including: using the smart cockpit to establish a service-oriented framework corresponding to the data distribution service based on the base class code file; and establishing a local service interface in the service framework based on the interface code file, wherein the local service interface is used to realize the interaction between the service language and the vehicle language.

[0053] Optionally, the method further includes: a base class code file including a first base class code corresponding to the service provider and a second base class code corresponding to the service caller; and an interface code file including a first interface code corresponding to the service provider and a second interface code corresponding to the service caller. If the smart cockpit is the service provider, a local service interface is established through the first base class code and the first interface code. If the smart cockpit is the service caller, a local service interface is established through the second base class code and the second interface code.

[0054] In some embodiments, if the intelligent cockpit is the service caller, a local service interface is established through SOA Proxy C++ code files and SOA Proxy JNI files; if the intelligent cockpit is the service provider, a local service interface is established through SOA Skeleton C++ code files and SOA Skeleton JNI files.

[0055] Optionally, before establishing a local service interface in the smart cockpit based on the service code file, the method further includes: generating a service package based on the dynamic library file and the service code file.

[0065] Step S208: Establish a local service interface in the service framework based on the interface code file;

[0066] Step S209: Call the dynamic library file through the local service interface to realize the intelligent cockpit calling data distribution service.

[0067] The data distribution service invocation method provided in this disclosure involves compiling the service function library into a dynamic library file using the vehicle-grade language, and generating a service code file using basic service information. This service code file then establishes a local service interface for calling the dynamic library file. Thus, even when the smart cockpit and the data distribution service use different code languages, the dynamic library file is called through the local service interface established in the smart cockpit, enabling smart cockpits using different languages ​​to invoke the data distribution service. This integrates the low latency and high reliability characteristics of the data distribution service, improving the transmission efficiency of the vehicle-grade smart cockpit.

[0071] The fill module 303 is used to fill in the basic service information into the preset code template to obtain the service code file;

[0072] The calling module 304 is used to establish a local service interface in the smart cockpit based on the service code file, and to call the dynamic library file through the local service interface to realize the smart cockpit calling data distribution service.

[0073] The data distribution service invocation system provided in this disclosure compiles the service function library into a dynamic library file according to the vehicle-mounted language, and generates a service code file based on the basic service information. This service code file then establishes a local service interface for calling the dynamic library file. Thus, even when the smart cockpit and the data distribution service use different code languages, the system enables smart cockpits using different languages ​​to call the data distribution service through the local service interface established in the smart cockpit. This integrates the low latency and high reliability characteristics of the data distribution service, improving the transmission efficiency of the vehicle-mounted smart cockpit.
