The invention discloses a vehicle-mounted play source quick switching method. The vehicle-mounted play source quick switching method comprises the following steps: loading a plurality of play source data to a system operating memory; setting a plurality of play source windows, respectively loading each play source data and UI resource corresponding to each play source, and respectively displaying interface information of a corresponding play source on each play source window; acquiring a switching signal of the play source in real time, and switching the audio channel of the current play source according to the switching signal; playing the play source data which are loaded to the system operating memory. The invention further provides a vehicle-mounted play source quick switching device. By implementing the technical scheme provided by the invention, a vehicle-mounted audio source can be switched quickly, the operating frequency of a user on a vehicle-mounted system during a driving process is reduced, the driving risk is reduced, the driving safety is improved, and the user experience is improved.
Description
technical field [0001] The invention relates to the technical field of vehicle audio playback, in particular to a method and device for fast switching of vehicle playback sources. Background technique [0002] With the rapid development of social economy and automotive electronics, the multimedia vehicle system has gradually become the standard configuration of the vehicle, and more and more rich multimedia technologies are continuously added to the vehicle intelligent terminal platform, such as MP3 and DVD vehicle players for audio-visual entertainment system, GPS car navigation system for driving assistance, and Bluetooth voice call system for wireless communication. However, there are many factors that affect driving safety, such as distracted consciousness, side-viewing, improper operation, etc. Among them, the driver's excessive frequency and increased frequency of operating the existing vehicle system is one of the important reasons affecting driving safety.
