Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] It should be noted that the terms "first", "second", etc. in this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so as to describe the embodiments of the present application described here.

[0053] The present invention provides a method and system for controlling an in-vehicle cinema, which is based on a SOA (Service-Oriented Architecture). If the cinema mode scene requirements change, only the application layer software needs to be modified without modifying the atomic service software, thereby realizing the user intelligent experience in various scene modes and satisfying the user's personalized settings in various scene modes.

[0054] SOA architecture is an architecture that applies service-oriented design patterns in automotive software. It is a software design method that modularizes the functions in the system into independent, reusable service units. These services communicate and cooperate through clear interfaces and protocols. In the automotive industry, SOA architecture helps to achieve high modularity, scalability and maintainability of automotive software systems, thereby improving the efficiency and quality of automotive software development.

[0055] like Figure 1 As shown, a car theater control system is configured with S0A service, including a central domain controller, a left area controller, a right area controller and an infotainment domain controller.

The motion control service obtains the vehicle speed information through the vehicle speed sensor, and the motion control service obtains the vehicle gear information and EPB status information through the EPB controller.

[0060] The infotainment domain controller is used to obtain vehicle status information from the central domain controller and determine whether the conditions for turning on the theater mode are met based on the vehicle status information and the theater mode function switch service status.

[0061] The infotainment domain controller is used to determine when the conditions for enabling theater mode are met, obtain user requirements through the application layer, and based on user requirements, call the infotainment control service to execute the corresponding theater mode function and send a theater mode enable instruction to the central domain controller.

[0062] The central domain controller is used to send the theater mode start instruction to the left zone controller and the right zone controller. The left zone controller executes the body control service according to the theater mode start instruction, and the right zone controller executes the thermal management control service according to the theater mode start instruction.

[0068] When the infotainment domain controller determines that the conditions for starting the theater mode are met, the infotainment domain controller executes the user preference setting service and reads the theater mode-related user-defined vehicle setting parameters stored in the memory; the vehicle audio control unit executes the audio control service and sets the audio effect to the theater mode audio effect; the infotainment domain controller executes the video playback service, displays the image information through the display screen, and controls the audio to play the audio data corresponding to the image information. The video playback service includes other vehicle video playback services and USB disk music and video playback services.

[0071] Based on the above-mentioned car theater control system, the present invention provides a car theater control method to collect all the demand information of the target car in the theater mode functional scenario. Based on SOA technology, functional software decoupling design is performed, and the functional software architecture is split into an atomic service layer and an application layer; according to the demand information corresponding to the target car theater mode functional scenario, the atomic service layer is divided into services with fixed requirements and services with user-defined requirements (services that provide modification interfaces); the execution order, execution logic and execution conditions of the atomic service layer and the application layer are respectively arranged to formulate the target car theater mode functional scenario service architecture.
