Multi-screen interaction method based on intelligent cabin

Abstract

The invention relates to the technical field of intelligent cabins, in particular to a multi-screen interaction method based on an intelligent cabin. The method comprises the following steps: establishing a server for Socket communication in a Linux system, and establishing a client for Socket communication in an Android system; enabling the Linux system to be started earlier than an Android system, and creating a Socket server side after the Linux system is started to wait for connection of a client side; after the Android system is started, establishing a Socket client, and connecting the Socket client with a Socket server in the Linux system; after the connection is established, enabling the Android to start a heartbeat packet mechanism; under the condition of normal connection, enabling the Android system to send navigation map data and other multi-screen interaction data to the Linux system, and enabling the Linux system to send a control instruction to the Android system; when disconnection is needed, enabling the Linux system to send a disconnection instruction to the Android system, so that the Linux system and the Android system are disconnected. According to the method, the connection is established between the Linux system and the Android system, and mutual transmission is carried out through data between every two systems, so the information sharing and interactionamong a plurality of screens are realized.

Description

technical field [0001] The invention relates to the technical field of smart cockpits, in particular to a multi-screen interaction method based on smart cockpits. Background technique [0002] Existing smart cockpits generally use the CarPlay system and the Mirrorlink system. The CarPlay system is a kind of car manufacturer or aftermarket machine manufacturer provided by Apple that allows users to use the touch screen or buttons (including steering wheel buttons, buttons, etc.) Center console buttons / knobs) and other interactive means to access the iPhone's phone calls, text messages, navigation, music, podcasts and other functions. The interaction between the in-vehicle entertainment system and the mobile phone enriches the functions of the in-vehicle central control entertainment system; the MirrorLink system refers to a "vehicle networking" standard jointly initiated and established by some internationally renowned mobile phone manufacturers and automobile manufacturers, ...

AI Technical Summary

Problems solved by technology

Both of the above have shortcomings to varying degrees. The CarPlay system is only limited to Apple mobile phones. Through CarPlay, the operations performed by the Apple mobile phone are moved to the central control display in the car. Because of the long certification cycle of CarPlay and the complicated review process, the entire The project development cycle is long; while the Mirrolink system is limited to multi-screen interaction and data transmission between the mobile phone and the central control, and the mobile phone terminal transmits the operation interface to the vehicle screen through the APP software, which makes it possible to connect with the mobile phone. The car screen cannot realize the interaction between the central control and the instrument, the central control and the head-up display HUD
