Description
Technical field
The invention belongs to automotive automation technical field, specifically a kind of vehicle based on automatic editor's cycle tests
Automated diagnostic tester system.
Background technology
Auto industry is developed rapidly, automobile function degree of integration more and more higher, the formed automobile controller for vehicle
Quantity is more and more, vehicle communication data exchange rate more and more higher.In order to preferably solve vehicle failure, maintenance effect is improved
Rate, accurate to find and recording controller functional fault, each main engine plants, which actively research and develop, releases the diagnostic techniques and dependence test of oneself
Instrument.
Each main engine plants（OEM）In each controller of test vehicle（ECU）System diagnostics function and basic diagnostic function
Following two patterns will be used：（1）Development phase manual test pattern,（2）Vehicle device mould is examined in the factory technics production automation
Formula.Wherein development phase manual authentication controller integrated diagnosis pattern is particularly important, but manual test needs to expend a large amount of
Time can just be controlled device fully certification, and serious forgiveness is higher.Test company exploitation based on CANoe, data diagnosis instrument
Though device automated diagnostic tester can be controlled Deng instrument, simple automatic test is only limitted to, and CAN diagnostic signals week can not be realized
Phase sends, and tests more single, and automatic test effect is undesirable.All start new automatic of research and development for this each main engine plants to examine
Disconnected system and method for testing, masses develop newest diagnostic tool software VCDS and diagnostic equipment 5054, and the software can be real
The 8 big left fund new car system diagnostics of main brand 100 such as Audi, Skoda, Lamborghini, Bentley, Porsche, lead under existing masses
It is high with rate.
At present, in the market occurs in that a kind of automatic editor's cycle tests（Test Automation Editor）Abbreviation TAE,
It is more advanced CAN testing tool, the instrument can be realized to be sent to vehicle CAN signal, CAN diagnostic signal cycles,
Also it can realize that a certain node of emulation bus realizes that bus control unit CAN message, bus CAN diagnosis message cycles are sent, such as 5 are
Product is to carry out diagnostic test using the instrument, is worked well.Nevertheless, but its exist deficiency be：Use the instrument
It is single test to carry out diagnostic test, can there is certain error, although tries and then eliminates error using increasing to measure, but survey
Method for testing still has deficiency.
The content of the invention
It is an object of the invention to provide a kind of vehicle automated diagnostic tester system of automatic editor's cycle tests based on TAE

Face unit can provide the host computer interface of whole system, realize that system control is operated with display, visual good, diagnostic test sequence
Row write unit and realize entire car controller diagnostic test by arranging diagnosis test sequence, and diagnosis test sequence, which writes unit, to be had
Control function, it is possible to achieve the integrated control of testing requirement, diagnosis message, which sends address location, can realize that system sends diagnosis
Message is diagnosed, diagnosis message retaking of a year or grade address location can realize that system diagnostics message is received；Diagnostic signal periodic conversion pattern bag
Containing two groups of dbc DBD database diagnostics message periodization units, the dbc DBD database diagnostics message periodization units refer to examining CAN
Break signal carries out periodization processing, the operation can be achieved the periodic conversion of CAN diagnostic signals in vehicle automated diagnostic tester system,
And can adjust the CAN diagnostic signal cycles and send the time；CAN, controller connector are vehicle automated diagnostic tester system
The passage being connected between tested controller, vehicle automated diagnostic tester system can level multiple controllers in parallel simultaneously, such as
Shown in Fig. 1, the system cascades N number of controller, and whole system can realize Single Controller diagnostic test, can also realize multiple
Controller diagnostic function integration testing.
The invention has the advantages that：The present invention is being introduced between editor's cycle tests instrument and controller connector automatically
Comprising two dbc DBD database diagnostics message periodization units in inventive point diagnostic signal periodic conversion pattern, the pattern, with diagnosis
The dbc DBD database diagnostics message periodization units that message sends address location connection are played transmission diagnosis request message periodization
Effect, embodiment can pass through the corresponding diagnosis request message Database Properties of modification, and redefine diagnosis request report
The literary transmission cycle；The dbc DBD database diagnostics message periodization units being connected with diagnosis message retaking of a year or grade address location are played and will received
The effect of diagnostic response message periodization, embodiment can by changing corresponding diagnostic response message data storehouse attribute, and
Redefine diagnostic response message and send cycle time；Described controller connector includes：Height matches somebody with somebody car body controller
（BCM）, just match somebody with somebody combination instrument（IC）, just match somebody with somebody air-conditioner controller（CCU）, just match somebody with somebody multimedia controller（MHU）, tire pressure prison
