Specific embodiment
The specific embodiment of the embodiment of the present invention is described in detail below in conjunction with attached drawing.It should be understood that thisLocate described specific embodiment and be merely to illustrate and explain the present invention embodiment, be not intended to restrict the invention embodiment.
Fig. 1 is the flow chart of vehicle device audio frequency playing method according to embodiments of the present invention, and this method can be used for such as leadingThe vehicle device of boat instrument, in-vehicle multi-media system etc..As shown in Figure 1, this method may comprise steps of：
In step S101, the mobile terminal to communicate simultaneously by bluetooth and USB interface with the vehicle device is determined.
For example, such as the mobile terminal of smart mobile phone, tablet computer etc., there is bluetooth communication and USB to connectMouthful, it can be connect by bluetooth equipment of the bluetooth wirelessly with such as vehicle device, can also wired side be passed through by USB interfaceFormula is connect with vehicle device, and in embodiment, mobile terminal can be connect and be communicated with vehicle device by bluetooth and USB interface simultaneously.
In step s 102, voice data communication strategy is sent so as to receive the audio to identified mobile terminalThe mobile terminal of data communication policy carries out voice data communication by USB interface and the vehicle device.
For example, communication strategy can be the communication control for controlling mobile terminal selection such as wired or wireless communication modeSystem strategy, communication mode can be selected according to the requirement of communication strategy by receiving the mobile terminal of communication strategy, in realityIt applies in example, vehicle device can send out the strategy that mobile terminal selection wired mode or USB interface communication mode is controlled to communicateIt send to mobile terminal so that the mobile terminal for receiving communication strategy stops or suspend Bluetooth communication, and USB interface is used to communicateCarry out the data transmission of such as audio data.
In step s 103, the audio data from mobile terminal is received via USB interface.
For example, by that will control mobile terminal that wired mode or USB interface communication mode is selected to communicateStrategy be sent to mobile terminal after, mobile terminal can be only by USB interface communication audio data, at this point, vehicle device can lead toIt crosses USB interface and carries out data interaction with mobile terminal.
In step S104, received audio data is played.
For example, vehicle device plays out the audio data received from USB interface, and the audio data of citing can beAudio data or lossless audio data with high bit rate etc..
It, can be with through the above technical solutions, when vehicle device and mobile terminal are communicated simultaneously by bluetooth and USB interfaceOnly by USB interface communication audio data, to realize the audio output of high quality.
In order to realize mobile terminal to being communicated by bluetooth and by the mobile terminal that USB interface communicates intoRow screening determines the mobile terminal to communicate simultaneously by bluetooth and USB interface in a manner that list is compared.Such as Fig. 2Shown, this method can include：
In step s 201, it obtains comprising the first row of the identifier of mobile terminal to be communicated by bluetooth with the vehicle deviceTable；
In step S202, the comprising the identifier of mobile terminal to be communicated with the vehicle device by USB interface is obtainedTwo lists；And
In step S203, identifier is existed simultaneously into the mobile terminal in the first list and the second listIt is determined as the mobile terminal to communicate simultaneously by bluetooth and USB interface with the vehicle device.
The shifting that can determine to communicate with the vehicle device by bluetooth and USB interface simultaneously by above-mentioned steps S201-S203Dynamic terminal.
For example, above-mentioned identifier can include one below person：Terminal name, terminal address, terminal number.Terminal nameIt can be the unit type that user is the self-defining name that terminal rises or mobile terminal.The citing of terminal address can be equipmentVirtual address or physical address.The citing of terminal number can be device id.Vehicle device is connected simultaneously with multiple mobile terminalsSituation about connecing, in embodiment, this method can also include：When simultaneously audio data is received from two or more mobile terminalsWhen, the audio data received from the mobile terminal with higher priority is played according to pre-set priority.It is mobile whole by settingThe priority at end can prevent data collision, preferentially to play the audio data from high priority mobile terminal.In embodimentIn, by taking android system as an example, vehicle device can be communicated by AoA agreements with mobile terminal.Wherein, communication strategy can be withIt is loaded into the AudioFlinger of mobile terminal.
Fig. 3 is the flow chart of vehicle device audio frequency playing method according to embodiments of the present invention, and this method can be used for such as intelligenceThe mobile terminal of energy mobile phone, tablet computer etc., this method can include：
It communicates in step S301, while by bluetooth and USB interface with vehicle device.
