The invention provides a screen projection method and system in an in-vehicle infotainment system, and the method comprises the steps: responding to a screen projection demand operation of a user, obtaining the to-be-projected data in real time through a central control end, and transmitting a screen projection instruction to an instrument display end through the central control end; in response to the screen projection instruction, controlling an RGB24 input interface of the instrument display end to be opened; through the RGB24 output interface of the central control end and the RGB24 input interface of the instrument display end, sending to-be-projected screen data obtained by the central control end to the instrument display end in real time for display; wherein the central control end is directly connected with the instrument display end. Therefore, the central control end is directly connected with the instrument display end, so that the screen projection data of the central control end can be directly sent to the instrument display end to be displayed, and the quality and the accuracy of data transmission are ensured.
本申请提供了一种车机系统内的投屏方法及系统,所述投屏方法包括:响应于用户的投屏需求操作,通过中控端实时获取待投屏数据,并由所述中控端向仪表显示端发送投屏指令;响应于所述投屏指令,控制所述仪表显示端的RGB24输入接口开启;通过所述中控端的RGB24输出接口和所述仪表显示端的RGB24输入接口,将所述中控端获取的待投屏数据实时发送至所述仪表显示端,以进行显示;其中,所述中控端与所述仪表显示端直连。这样,通过将中控端和仪表显示端直连,使得中控端的投屏数据可直接发送至仪表显示端进行显示,从而保证了数据传输的质量和准确性。
