Abstract

The invention provides a vehicle-mounted system and a subject interface switching method of an instrument displayer thereof. A subject interface comprises own frames of the instrument displayer and video frames transmitted to the instrument displayer by an information amusement main machine. The method comprises the following steps: the instrument displayer sends subject interface switching requests with target subject interface marks to the information amusement main machine; the information amusement main machine switches the video frames according to the target subject interface marks in the received subject interface switching requests; if switching is successful, the information amusement main machine sends switching successful information to the instrument displayer, and sends videoframe data corresponding to the target subject interfaces to the instrument displayer; and after the instrument displayer receives the switching successful information and the video frame data corresponding to the target subject interfaces, the present subject interfaces are switched to target subject interfaces. The time sequences are synchronously switched through information interaction, so that the switching speed is high, and reasonable display modes after switching are guaranteed.

Description

technical field

[0001] The invention relates to the technical field of vehicle-mounted infotainment products, in particular to a vehicle-mounted system and a method for switching theme interfaces of an instrument display of the vehicle-mounted system. Background technique

[0002] At present, in some vehicle-mounted systems, especially in-vehicle entertainment systems, the instrument display (also called Dash Integration Module, DIM for short) is used in addition to displaying vehicle speed, engine speed, mileage and other information related to the instrument itself. In addition, other media information, such as navigation information, phone information, music information, etc. will be displayed. The media information is transmitted to the instrument display by an infotainment head unit (Infotainment Head Unit, IHU) through, for example, low-voltage differential signaling (Low-Voltage Differential Signaling, LVDS) video output. Instrument information such as vehicle speed ...
