The invention discloses a screen projection method and device, equipment and a medium. The method comprises the following steps: in response to a navigation function starting instruction, generating a first map layer handle corresponding to a target map picture; the first map layer handle is sent to a connected vehicle instrument system, so that the vehicle instrument system directly reads map data of a vehicle central control system according to the first map layer handle, and the target map picture is displayed on an instrument panel. According to the embodiment of the invention, the problem that the frame rate is reduced due to the fact that map data is copied for multiple times in the prior art is solved, and the screen projection frame rate and the user experience are improved. 本发明公开了一种投屏方法、装置、设备和介质。该方法包括：响应于导航功能启动指令，生成目标地图画面对应的第一地图图层句柄；将所述第一地图图层句柄发送至所连接的车辆仪表系统，以使所述车辆仪表系统根据所述第一地图图层句柄直接读取车辆中控系统的地图数据，并将所述目标地图画面显示在仪表盘上。本发明实施例解决了现有技术中将地图数据进行多次拷贝导致帧率降低的问题，提高了投屏的帧率和用户体验度。
