It can become more sophisticated, while also bring new challenge to exploitation test.It is enclosed in conventional vehicle multiple electric parts
Interior communication is different, and T-BOX with background server or other terminals by wirelessly being communicated.Complete car networking system this
One closed loop test verifying, on the one hand need give T-BOX simulation real vehicle environment, on the other hand need the data packet to wireless telecommunications with
And the final display or response results in backstage is monitored.But for the T-BOX for having remote failure record and diagnostic function, such as
What simulation real vehicle environment, especially various unusual service conditions, the simulation that failure is manually set, triggering, conventional means of testing are difficult to
Meet, and also because difficulty, the drive safety etc. of direct fault location are difficult to carry out in the way of real steering vectors.
Summary of the invention
In view of the above defects of the prior art, the purpose of the present invention is to provide a kind of intelligent networks to join functional development
HIL test method in the process.
The present invention is achieved through the following technical solutions:
A kind of HIL test method for car networking performance test, it is online for T-BOX Simulation Diagnosis instrument, long-range to carry out
The functional requirement of fault diagnosis, by vehicle HIL test macro, background server and client comprising direct fault location unit (FIU)
Terminal composition.Firstly, direct fault location unit, which can simulate, generates electric information, bus type, function in vehicle HIL test macro
The failures such as class, including the failure under real vehicle cannot achieve or be difficult to realize limiting condition, such as sensor, controller, actuator
Route disconnects suddenly, function catastrophic failure etc.；Secondly, according to diagnosing protocol, passing through CAN bus while simulation generates failure
The failure that monitoring record tool generates simulation confirmed and recorded, for the evaluation of T-BOX remote fault diagnosis data with sentence
It is disconnected that foundation is provided；It is instructed finally, client assigns fault diagnosis to T-BOX by server, and diagnostic data is shown in visitor
Family end by the diagnostic data of T-BOX feedback shown in client and uses the simulation event of CAN bus monitoring record tool records
Barrier data compare verification, verify to T-BOX remote fault diagnosis function.
The specific steps of which are as follows:
Step 1: vehicle HIL test macro is adjusted to cascade mode, i.e., it is power domain, chassis domain, comfortable domain and driving is auxiliary
It helps domain HIL system cabinet all to connect step by step, confirms that all system functions operate normally；Tested T-BOX is connected to whole HIL by confirmation
Designated position and system electrification are normal in system；
Step 2 manipulates direct fault location board by upper computer software, simulation generates electricity in vehicle HIL test macro
Gas class or bus type failure, while according to functional fault correlated condition, the vehicle HIL system simulation of manipulation generates function class failure；
Step 3: according to power domain, chassis domain, comfortable domain and the fault diagnosis agreement for driving auxiliary domain related controller,
Establish fault diagnosis environment in CAN bus monitoring record tool, i.e., the new construction in CAN bus monitoring record tool, so
The diagnostic data library file (CDD file) of related controller is loaded afterwards, finally confirms that fault diagnosis communication is normal；Simulated failure
Meanwhile being confirmed and being recorded by failure of the CAN bus monitoring record tool to generation, on the one hand ensure to simulate generation failure
On the other hand accuracy provides foundation for the evaluation and judgement of T-BOX remote fault diagnosis data；
Step 4: T-BOX is connect with background server by wireless communication, client (including pc client and mobile visitor
Family end) it is accessed by internet to background server；Remote failure is assigned to T-BOX by server using client to examine
Severed finger enables, and diagnostic data is uploaded to background server, then shown on the client by T-BOX；
Step 5: remembering by the diagnostic data of T-BOX feedback shown in client and using CAN bus monitoring record tool
The simulated failure data of record compare verification, verify to T-BOX remote fault diagnosis function.
Further, electric information failure described in step 2 includes that PIN foot open circuit, short circuit, motor rotation blockage or switch are adhered.
Further, bus type failure described in step 2 includes bus node loss or bus message time-out.
Compared with prior art, advantages of the present invention is as follows:
Test method of the invention can not only simulate the failure under the limiting condition that real vehicle cannot achieve or be difficult to realize,
And can be confirmed and be recorded using the failure that CAN bus monitoring record tool generates simulation according to diagnosing protocol, with
Verifying is compared in the data that T-BOX is uploaded to background server, provides for preferably verifying T-BOX remote fault diagnosis function
A kind of effective technological means and test method.
Detailed description of the invention
Fig. 1 is the HIL test macro schematic diagram for car networking performance test of the invention
Specific embodiment
The present invention is described further with reference to the accompanying drawing.
Embodiment 1:
Step 1: vehicle HIL test macro is adjusted to cascade mode, i.e., it is power domain, chassis domain, comfortable domain and driving is auxiliary
It helps domain HIL system cabinet all to connect step by step, confirms that all system functions operate normally；Tested T-BOX is connected to whole HIL system
Then middle designated position normally powers on vehicle HIL system；
Step 2 manipulates direct fault location board by upper computer software, simulation generates vehicle in vehicle HIL test macro
Body controller left steering lamp PIN foot open-circuit fault, while in vehicle HIL test macro, open left steering lamp switch, left steering
Lamp is not worked normally due to failure.
Step 3: being created in CAN bus monitoring record tool according to the fault diagnosis agreement of comfortable domain car body controller
Then engineering loads the diagnostic data library file (CDD file) of car body controller, finally confirm that fault diagnosis communication is normal；Step
Simulation generates car body controller left steering lamp PIN foot open-circuit fault in rapid two, therefore, by CAN bus monitoring record tool
Fault diagnosis engineering, read car body controller there is currently failure, engineering interface show left steering lamp PIN foot open-circuit fault letter
Breath, at this time, it is ensured that simulation generates the accuracy of car body controller left steering lamp PIN foot open-circuit fault, while to reading
Fault message is stored, and provides foundation for the evaluation and judgement of T-BOX remote fault diagnosis data.
Step 4: pc client accesses to background server by internet, T-BOX is by wireless communication and backstage
Server connection；Therefore, remote fault diagnosis is assigned to T-BOX by server using pc client to instruct, read vehicle body control
Diagnostic data is uploaded to background server by device current failure processed, T-BOX, and then pc client shows that left steering lamp PIN foot is opened
Road fault message.
Step 5: by the fault message that stores in the diagnostic data and step 3 of T-BOX feedback shown in client into
Row comparison verification, finally, the information such as car body controller left steering lamp PIN foot open-circuit fault code, defect content are consistent.
