As shown in Figure 1, the application provides a kind of onboard system applied to car networking, including：
Application layer is configured to execute the application program for being stored in vehicle interior, such as Navigator, video/audio
Playing program etc..For Navigator, traditional usual its needs to obtain locating module acquisition by accessing CAN bus
Location information data after just execute corresponding Navigator, in entire navigation procedure, CAN bus need ceaselessly from positioning
Location information data is obtained at module and is ceaselessly sent to Navigator.Further, when vehicle reaches purpose by navigation
When near ground, navigation software usually has the function of recommending parking lot, at this time if further showing that each parking lot is surplus to user
When remaining parking stall quantity, need to access internet or high in the clouds data.
Certainly, it will be appreciated by persons skilled in the art that the application service layer applies journey in addition to user is visible
Further include the not noticeable application program of some users other than sequence, such as obtains what the camera being arranged on vehicle was acquired
Whether carriageway image analysis vehicle shifts, and decides whether the application journey of adjustment direction of traffic or speed according to analysis result
Sequence.
Bus layer is configured to execute vehicle internal data transmission.General in vehicle all includes CAN bus, CAN bus connection
Each back end of interior each sensor or vehicle interior, for example, engine electric-controlled system, automatic transmission control system
System, anti-lock braking system (ABS), automatic cruising system (ACC) and in-vehicle multi-media system etc., between these systems, and
It is required to carry out data exchange between these systems and the display instrument of automobile, between system and vehicle fault diagnosis system, this
A little data interactions are completed by CAN bus.On the other hand, the bus of vehicle generally includes two types, a kind of
It is STD bus, includes data content, data type, data format, reading/writing method etc. by the transmission of STD bus access interface,
Another bus type is manufacturer's bus, realizes that STD bus access interface is own total to manufacturer by manufacturer's bus access driving
The two-way translation of wire protocol, is generally realized by manufacturer.STD bus access interface described herein can take to vehicle-mounted agency
The otherness of business layer mask bus and the bus protocol for keeping vehicle manufacturer secrecy own.
Cloud Server can carry out data processing beyond the clouds and be sent to handling result through wireless communication
Vehicle, meanwhile, Cloud Server can equally obtain related data and the request of vehicle through wireless communication.
Vehicle-mounted agency service layer is configured to access the bus layer, and/or cloud in response to the request of the application layer
Server.The vehicle-mounted agency service layer of the application can be an independently operated software, can equally have hardware carrier.Such as
