Description
Technical field
The present invention relates to the automotive automation field, relate generally to body control system functional configuration and In-vehicle networking communication and On-Board Diagnostics (OBD) aspect.
Background technology
Automotive automation mainly comprises automobile function configuration, CAN network communication and On-Board Diagnostics (OBD) aspect.
1, automobile function configuration
Along with the development that leaps of automotive electronic technology, more and more electronics applications to improve comfortableness, the operational stability of car, reduce aspects such as noise, the low oil consumption of safety and health in automobile.At present external automotive electronics widespread usage on automobile, it accounts for the car load price ratio and reached 60%-70% in some luxury car.The application of automotive electronics makes that the international competition of automobile is more and more fierce, and increasing automaker adds in the international automotive field competition.In the automobile international competition, on the one hand, country variant is different with humanity, geography, the custom in zone, has determined their hobby to automobile, the different requirements of configuration; On the other hand, the branch that disposes class of automobile itself, even the same region of same country, because the difference of the level of consumption, automobile is realized different configurations, as economical, standard form, comfort type etc.Concerning controller, different configurations, the load difference, as being discerned with Part No., Part No. increases, and difficult management.
2, CAN mechanics of communication
This is one of most widely used controller communication bus on the automobile.Just as the usefulness of the controller communication in the automotive environment, exchange message between Vehicular electronic control unit ECU forms the Vehicle Electronic Control network during CAN-BUS initial designs.Such as: in engine management system, gearbox control, instrument equipment, the electronics trunk system, all embed the CAN communication device.The CAN bus by simple agreement, realized the reliable transmission of remote real time data under electromagnetic interference environment, and hardware cost is lower owing to adopted many new technologies and unique design.Compare with general communication bus, have outstanding reliability, real-time and dirigibility.The major defect of CAN bus is that cost is more higher than relatively, and is very low for communication speed, and the node that interstitial content is few and quantity of information is little is relatively wasted resource.
3, On-Board Diagnostics (OBD) technology
Developing by leaps and bounds of automotive electronic technology brings vehicle diagnosis The Application of Technology and progress, current vehicle diagnosis technology is used at home as yet and is not popularized, even electronic control module possesses diagnostic function, also only only limit to read and remove diagnostic trouble code in the controller, seldom use other function of diagnostic techniques.And the vehicle diagnosis technology more than that, and vehicle diagnosis technology and the inner specific function of automobile controller are combined into a new developing direction.
Carry out diagnosis communication and need follow the certain communication standard, KWP2000 is present used diagnosis communication standard widest in area, it is the very perfect vehicle-mounted fault diagnosis consensus standard of a cover, the hierarchy of agreement makes KWP2000 Diagnosis Service and do not rely on certain particular network medium, and its application layer can be transplanted on any Physical layer and the data link layer protocol.The K radiodiagnosis x is one of diagnostic-type the earliest, at present based on the KWP2000 (its international standard ISO 15765) of CAN bus, has complied with the megatrend of In-vehicle networking development, will progressively replace the K radiodiagnosis x, becomes one of main flow of On-Board Diagnostics (OBD) of future generation.
In the CAN diagnostic message, frame data format is as follows:
Table one CAN frame data format
| PCI | Data Field |
| Protocol-control-information | The application layer data byte |
PCI and Data Field are the concrete data content of frame data.It is single frames or multiframe that the PCI protocol-control-information is used for indicating the CAN diagnostic data, and the length of frame is provided.Data Field comprises the data message of 1-7 byte, and the Diagnosis Service of diagnosis communication and Diagnostic parameters are just in data field.
Summary of the invention
Purpose of the present invention just provides a kind of collocation method of realizing the body control system functional configuration by diagnosis communication, utilize the CAN diagnostic techniques, car body controller is carried out functional configuration, allow it discern configuration variation of each system of car load automatically, under the constant situation of design software and hardware, by software masking with enable the control that corresponding system device is realized the body control system functional configuration.
The technical solution used in the present invention is: a kind of collocation method by diagnosis communication realization body control system functional configuration may further comprise the steps:
Connection diagnostic testing apparatus and car load diagnose interface;
The diagnostic test device power according to the prompting of the display screen interface of diagnostic device, is selected corresponding vehicle, clicks and enters corresponding vehicle diagnostic system;
According to the diagnostic device interface prompt, select and click the car body controller system.
The major function of car body controller is by the input of each switch and variation, opposite house, and glass lifting, the headlight lampet is enabled, windscreen wiper, defrost function, cruise function is controlled.In the design process, utilize the existing hardware of car body controller, by the analysis configuration table, list the main difference of different configurations, form the diagnosis configuration parameter, utilize the concrete Diagnosis Service of diagnosis communication to realize the concrete configuration of automobile, reach the function that automobile is discerned self configuration automatically.
Description of drawings
Fig. 1 is the realization flow figure of functional configuration of the present invention.
Embodiment
To use Diagnosis Service in the diagnosis communication implementation procedure.What this functional configuration was mainly used is that the write data service realizes (Write data by local identifier).The service identifier of write data service is 3B, and the form of write data Service Diagnostic communication request order is as shown in the table:
