It is upper that described data acquisition fault diagnosis module is connected to vehicle ECU, Real-time Collection vehicle every data message in the process of moving.
Described acoustics unit connects and controls wifi camera, and wifi camera sends to by smart mobile phone the image information collecting on car networked server.
Described car networked server sends instructions on smart mobile phone by network, and smart mobile phone is by the MCU of bluetooth communication module control acoustics unit, and MCU starts corresponding operation after receiving instruction; Described operation comprises that controlling radio, CD Player, vehicle carried data collecting, vehicle-mounted fault diagnosis and startup Wifi camera carries out remote monitoring.
Described smart mobile phone is delivered to voice data the audio processing modules of acoustics unit by bluetooth communication module, realize the Music centre loudspeaker output mobile phone audio-frequency data by car load.
The key information of described acoustics unit and voice control information are delivered on smart mobile phone by bluetooth communication module, in acoustics unit, smart mobile phone are operated.
A kind of information of vehicles communication system, owing to adopting above-mentioned structure, the invention has the advantages that: 1, utilize the screen of smart mobile phone to realize the function of vehicle-carrying display screen, improve Driving; 2, outwards transmit in real time information of vehicles by smart mobile phone, improve the security performance of Vehicle Driving Cycle; 3, make full use of smart mobile phone, in guaranteeing the realization of vehicle various functions, at utmost reduce production costs.

Embodiment
The present invention expands integration on automobile audio field and smart mobile phone technology platform, particularly use the on-vehicle acoustic apparatus with Bluetooth communication and vehicle data collection, car fault diagnosis, vehicle audio and automobile CAN-bus network information gathering, high-fidelity sound are play and intelligent mobile phone platform APP application and development of Mobile Internet technology application organically combine vehicle audio is cheaply upgraded to the mobile message recreation terminal that car is networked.
As Figure 1-5, the present invention is that the acoustics unit 1 of automobile is connected respectively on data acquisition fault diagnosis module 2 and bluetooth communication module 3, bluetooth communication module 3 is connected to by bluetooth on the smart mobile phone 4 of human pilot, and smart mobile phone 4 carries out communication by network with the car networked server 5 of automobile services operator again and is connected.It is upper that data acquisition fault diagnosis module 2 is connected to vehicle ECU6, Real-time Collection vehicle every data message in the process of moving.Acoustics unit 1 connects and controls wifi camera 7, and wifi camera 7 sends to by smart mobile phone 4 image information collecting on car networked server 5.
Car networked server 5 sends instructions on smart mobile phone 4 by network, and smart mobile phone 4 is controlled the MCU of acoustics unit 1 by bluetooth communication module 3, and MCU starts corresponding operation after receiving instruction; Described operation comprises that controlling radio, CD Player, vehicle carried data collecting, vehicle-mounted fault diagnosis and startup Wifi camera 7 carries out remote monitoring.Smart mobile phone 4 is delivered to voice data the audio processing modules of acoustics unit 1 by bluetooth communication module 3, realize the Music centre loudspeaker output mobile phone audio-frequency data by car load.Key information and the voice control information of acoustics unit 1 is simultaneously delivered on smart mobile phone 4 by bluetooth communication module 3, in acoustics unit 1, smart mobile phone 4 operated.
Vehicle-mounted acoustics unit 1 and the smart mobile phone 4 with bluetooth are formed communication network system by the present invention, sound equipment and car CAN bus composition in-vehicle network infosystem, smart mobile phone 4 and internet composition Mobile Internet system, by bluetooth by automobile and the interconnected vehicle-mounted information and entertainment system of realizing low cost, the resource sharing of high intelligent vehicle hand set of mobile phone.The present invention utilizes two-way communication between the display screen of smart mobile phone and application program and vehicle audio to bring stronger interactive multi-mode to experience.Vehicle audio unit 1 is as stereo set, car-mounted terminal and the control terminal of smart mobile phone 4.Smart mobile phone 4 is as display screen, player, navigating instrument and the car networking terminal etc. of vehicle audio unit 1.
Bluetooth communication module 3 connects vehicle audio and user's smart mobile phone 4 has formed wireless communication networks in car, and user's smart mobile phone 4 is installed special communication process software to realize by mobile phone interface and automobile exchange message object.Vehicle audio uses physical button or voice, controls smart mobile phone 4 by bluetooth communication module 3; Smart mobile phone 4 is controlled vehicle audio unit 1 by bluetooth communication module 3 and is completed vehicle data collection, fault diagnosis, remote monitoring, smart mobile phone can be sent to parking lot data server by wireless Internet (as 3G, GPRS, WIFI, 4G) again and store, analyzes, processes, to realize the part basic function of car networking.
Smart mobile phone 4 utilizes particular network (2G, 3G or 4G) to send instruction by specific application program operation interface or car internet services operator, instruction is sent to the MCU of vehicle audio unit 1 through bluetooth communication, MCU starts corresponding operation after receiving instruction, carries out the operations such as remote monitoring as controlled radio, CD Player, vehicle carried data collecting, vehicle-mounted fault diagnosis and startup Wifi camera 7; Smart mobile phone 4 is delivered to the audio processing modules of acoustics unit 1 by bluetooth communication module 3 simultaneously, finally by the Music centre loudspeaker output mobile phone audio-frequency data of car load.
