Embodiment

[0042] Example: see Figure 1-Figure 2 ,

[0043] A method for implementing message decoupling between vehicle APP modules, comprising the following steps,

[0044] S1. The in-vehicle APP is divided into a UI layer for user operation and a business logic layer for providing various services. The UI layer only contains UI-related drawing and control codes. Business logic layer contains all business logic code.

[0045] S2. Set up a message call framework between the UI layer and the business logic layer;

[0046] S3. The business logic layer registers the services it provides with the message invocation framework;

[0047] S4. The UI layer registers the message monitoring of each service with the message calling framework;

[0048] S5. Call service: When the user calls the required service by operating the UI layer, the user sends a call message to the message call framework, and the message call framework forwards the call message to the corresponding service in the busin...

Abstract

The invention discloses a method and a system for realizing message decoupling between vehicle-mounted APP modules. The method comprises the following steps: S1, dividing a vehicle-mounted APP into a UI layer and a business logic layer; s2, setting up a message calling framework between the UI layer and the business logic layer; s3, the service logic layer registers services provided by the message calling framework to the message calling framework; s4, the UI layer registers message monitoring of each service to the message calling framework; s5, calling a service; and S6, message monitoring. When the modules are called, specific calling can be completed through different parameters of the same interface, the expandability of interface calling is guaranteed to the maximum degree, and the problem that a large amount of compilation is caused by modification among the modules when multiple persons cooperate for development is avoided.

Description

technical field [0001] The invention belongs to the field of vehicle APP technology, and more specifically relates to a method and system for realizing message decoupling between vehicle APP modules. Background technique [0002] The vehicle-mounted system is the interface between the user and the vehicle-mounted hardware, as well as the interface between the vehicle-mounted hardware and the upper-layer software. The functions of the vehicle-machine operating system include managing the hardware, software and data resources of the vehicle system, controlling the operation of the program, improving the man-machine interface, and providing support for the upper-level software. The in-vehicle APP utilizes the resources of the in-vehicle system to maximize the effect of received data, signals, audio, and video, and provides various forms of user interface (UI), so that the driver has a good driving environment and effectively provides Assisted driving, semi-autonomous driving, ...
