sending display system identification information of the main driving display system and time information of playing information played last in the vehicle, which is acquired by the main driving playing device, to the vehicle-mounted entertainment system (for example, the playing information played last acquired by the main driving playing device is a qilixiang song, and the playing time is 10: 00 min);
the display system identification information of the copilot display system and the time information of the last playing information in the vehicle, which is acquired by the copilot playing device, are sent to the vehicle-mounted entertainment system (for example, the last playing information acquired by the copilot playing device is a northbound song, and the playing time is 10: 01 minutes);
the vehicle-mounted entertainment system acquires display system identification information corresponding to time information closest to vehicle restart time in time information of playing information played last in each vehicle (in the embodiment, one northward playing time is closer to the vehicle restart time), and a driving display system corresponding to the display system identification information is a display system to be controlled (in the embodiment, a copilot display system is used as a display system to be controlled);
the vehicle-mounted entertainment system generates a media control signal according to the display system identification information;
the vehicle-mounted entertainment system sends the media control signal to a display system to be controlled (namely a copilot display system) so that the copilot playing device sends the control signal to a music module playing a path of northward, and the music module calls information to be played, so that the vehicle only plays the path of northward which is not played yet.
In one embodiment, before playing a road to the north, the present application further determines whether there is a passenger at the secondary driving position, for example, the vehicle is a taxi, and there is a passenger who may be in front of the secondary driving and listen to the road to the north, however, when the vehicle is turned off, the passenger who is in the secondary driving has got off the vehicle, and after the vehicle is restarted, there is no passenger at the secondary driving, and at this time, it is necessary to determine whether there is a passenger by recognizing the image of the riding position corresponding to the secondary driving display system, and if not, it is not necessary for the in-vehicle entertainment system to send the media control signal to the display system to be controlled, thereby preventing resources from being wasted and preventing inconvenience of the driver in closing after opening.
In this embodiment, the vehicle multimedia refers to a vehicle multimedia Architecture, car Media Architecture, CMA for short.
Referring to fig. 3 and 4, in the embodiment, the CMA architecture includes a CarMedia, a carmediservice, and a mediabrowse service, and the CarMedia presentation layer is an interface presentation layer and is dedicated to album list presentation and song information display. The CarMediaService is used for uniformly managing all MediaBrowserService audio services; the mediabrowser service is a normalized abstract class, all music including third-party music software is inherited from the mediabrowser service, and the class can provide external interfaces such as interface browsing and player control and the like for the unified calling of the caremediaservice.
