In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
Fig. 1 and Fig. 2 is please referred to, Fig. 1 is a kind of side that vehicle device is interacted with mobile phone audio-frequency data provided in an embodiment of the present invention
The flow chart of method, Fig. 2 are a kind of main schematic diagram of vehicle device and mobile phone interaction provided in an embodiment of the present invention.
The method that the vehicle device is interacted with mobile phone audio-frequency data is applied to mobile phone, comprising:
Step S1: after mobile phone is connect with vehicle device by USB data line, crawl mobile phone terminal former audio data being played on
Stream.
Specifically, mobile phone can be connect with vehicle device by USB data line by car owner after getting on the bus, after the two connects, vehicle
Chance detects that mobile phone has been inserted into, and mobile phone equally also detects that itself to be connect with vehicle device, and vehicle device can be on a display screen at this time
Display " whether entering interactive service " or mobile phone show " whether entering interactive service " on a display screen.If car owner needs vehicle
Machine is interacted with mobile phone, and " entering interactive service " may be selected；It interacts, may be selected with mobile phone if car owner does not need vehicle device
" not entering interactive service ".After car owner's selection " entering interactive service ", when mobile phone terminal plays audio, mobile phone can be by rear
Platform service routine crawl former voice data stream being played on, carries out audio transmission for both later periods and prepares.
Step S2: former voice data stream is converted into the voice data stream suitable for USB transmission.
Specifically, in order to make mobile phone and vehicle device transmit audio by USB data line, mobile phone is being grabbed by background service program
While taking former voice data stream being played on, former voice data stream is also converted into the audio data suitable for USB transmission
Stream, to make voice data stream at this time that can transmit by USB data line.
Step S3: voice data stream is sent to vehicle device by USB data line, so that vehicle device solves voice data stream
Code is simultaneously played out in engine end.
Specifically, the voice data stream suitable for USB transmission that mobile phone can will convert into real time is sent by USB data line
To vehicle device (vehicle device self-carried USB driver and usb communication program, i.e. vehicle device just have USB transmission function originally).Vehicle device is connecing
