Under the guiding of the thinking, this programme embodiment provides following feasible embodiment.
Embodiment one
The embodiment of the present invention provides a kind of test method of battery management system.
Referring to FIG. 1, the flow diagram of the test method of its battery management system provided by the embodiment of the present invention,
As shown in Figure 1, this approach includes the following steps：
S101 instructs in response to test, obtains the target detection use-case of BMS.
The test method for the BMS that the embodiment of the present invention is provided can be applied in the test system of BMS.
Specifically, in the embodiment of the present invention, the target detection use-case of BMS can include but is not limited to：Test event and survey
Try target.
Wherein, test target is used to indicate partly tests for which in BMS, for example, can using entire BMS as
Test target；In another example can also be using certain units in BMS as test target.Test event is used to indicate to testing mesh
Mark carries out the test in terms of which, and test event can include but is not limited to：Total system test, data input and output DIO tests
At least one of with automobile open system framework AUTOSAR test, the embodiment of the present invention is to this without being particularly limited to.
S102, obtains the corresponding test script of target detection use-case, and test script includes emulation signal message.
S103 generates emulation signal according to emulation signal message.
It should be noted that in the embodiment of the present invention, emulation signal can include but is not limited to：Voltage signal, electric current letter
Number, at least one of digital signal, pulse width modulation (PWM) signal and CAN message signal.
During actually realizing this programme, for different target detection use-cases, the emulation signal of generation is also different.
If for example, carrying out system testing to BMS, the emulation signal generated may include above-mentioned six kinds of signals；If carrying out DIO to BMS
Test, then the emulation signal generated may include：Voltage signal, current signal, digital signal and pwm signal etc.；If to BMS into
Row AUTOSAR tests, then the emulation signal generated may include：Voltage signal, CAN message signal and software variable signal etc..
It is only for for example, being not intended to limit the scope of the invention.
S104 exports emulation signal to BMS.
S105 obtains status informations of the BMS after input emulates signal.
S106 obtains the test result of BMS according to status information.
The test method of BMS provided in an embodiment of the present invention can be applied in the test system of BMS, and user can basis
It needs to operate in test system, and test instruction is sent to the test system.
During practical application this programme, it can be previously stored with candidate test case in the test system of BMS, use
Family can be operated in candidate test case, selection target test case, which can trigger generation test instruction, ring
It should be instructed in the test, determine target detection use-case.Alternatively, life can also be triggered by inputting the title of target detection use-case
It is instructed at test.
It should be noted that in the embodiment of the present invention, it can be by the storage corresponding with test script of candidate test case, this
Sample can execute the step that the corresponding test script of target detection use-case is obtained in S102 after determining target detection use-case
Suddenly.
In addition, it is contemplated that may not have the case where target detection use-case in candidate test case.If for example, BMS
The test instruction that test system receives is issued by searching for mode, then, it is possible in the test system that can have BMS
The case where target detection use-case is not stored.
Therefore, can be when executing S102 during a concrete implementation, the target detection that will be got in S101
Use-case is matched with several candidate test cases, in this way, when there is the candidate test case to match with target detection use-case
When, so that it may to obtain the corresponding test script of candidate's test case, using as the corresponding test script of target detection use-case.
Alternatively, when there is no the candidate test case to match with target detection use-case, prompt message can be exported, with
It can be according to the prompt message input test script, it is thus possible to obtain the test inputted according to the prompt message convenient for user
Script, using as the corresponding test script of target detection use-case.
Specifically, during actually realizing the step, if desired user is according to the prompt message input test script,
These scripts can be transplanted, be used for reference and be encapsulated from other corresponding test scripts of candidate's test case as needed.Example
Such as, can be by the corresponding test script of candidate test case, a part of test script with identical artificial intelligence is answered
System, and affix in test script input by user.
It should be noted that when target detection use-case is matched with several candidate test cases, it is contemplated that candidate surveys
Example on probation can have it is multiple, as long as an at this point, candidate test case phase in target detection use-case and candidate test case
Match, is considered as the presence of the candidate test case to match with target detection use-case, at this point, the corresponding test of candidate's test case
Script is exactly the corresponding test script of target detection use-case.On the other hand, when target detection use-case and whole candidate tests are used
When example all mismatches, it just will be considered that there is no the candidate test cases to match with target detection use-case.
When specifically being matched to target detection use-case and candidate test case, the identification information that both can utilize into
Row matching thinks exist when the identification information that there is candidate test case is consistent with the identification information of target detection use-case
The candidate test case to match with target detection use-case.Identification information can be preset according to actual needs, and the present invention is real
Example is applied to this without being particularly limited to.
For example, identification information is the title of test case, then the title of several candidate test cases is used with target detection
The title of example is matched successively, if there are the titles complete one of the title and target detection use-case of a candidate test case
It causes, determines the candidate test case for existing and matching with target detection use-case.
Alternatively, in another example, if identification information is test event and test target, by the test of several candidate test cases
Project is matched successively with the test event of target detection use-case, meanwhile, by the test target of several candidate test cases with
The test target of target detection use-case is matched successively, when there are a candidate test case, this candidate test case
Test event and test target all with the test event and all completely the same test target of target detection use-case when, determine exist with
The candidate test case that target detection use-case matches；Alternatively, as long as there are a mismatches in the two matching process, determine
There is no the candidate test cases to match with target detection use-case.
In the embodiment of the present invention, if after obtaining the test script inputted according to prompt message, storage evidence can be corresponded to and carried
Show the test script and target detection use-case of information input, in this way, being equivalent to the candidate test stored in the test system to BMS
Correspondence between use-case and test script is updated, to encounter identical target survey carrying out test to BMS later
When example on probation, does not need user and input identical test script again, but can be according to the correspondence of corresponding storage before this
The corresponding test script of target detection use-case is got, the step of executing automatically and complete S102.
In the embodiment of the present invention, after executing S102 and getting the corresponding test script of target detection use-case, so that it may with straight
It connects and executes the step of generating emulation signal in S103.
It should be noted that including emulation signal message in the embodiment of the present invention, in test script, signal message is emulated
It can include but is not limited to：Emulate the concrete numerical value of signal.Based on this, in S103, so that it may with according to the information of emulation signal
Simulations signal.
For example, when the emulation signal message instruction in test script：It, can be with when voltage signal is 5V, current signal is 1A
The voltage signal that numerical value is 5V and the current signal that numerical value is 1A are automatically generated according to these emulation signal messages.
The test system of BMS provided in an embodiment of the present invention can have been obtained according to the information of artificial intelligence compared with high precision
The emulation signal of degree, for example, the accuracy of power supply signal can reach ± 100mV, the accuracy of voltage signal can reach
200mV, the accuracy less than 100 Ω resistance signals can reach ± 2 Ω, the resistance signal between 100 Ω and 10k Ω
Accuracy can reach ± 2%, and the accuracy of the resistance signal between 10k Ω and 150k Ω can reach ± 2%.
And, it is no longer necessary to user modulates manually and analog simulation signal, is also just no longer influenced by user hand and moves analog signal
The influence of caused numberical range can so that emulating signal has broader numberical range.For example, the numberical range of voltage signal
0~40V can be increased to, and the numberical range of resistance signal increases to：10 Ω~150k Ω.
Moreover, in the embodiment of the present invention, the test system response time of BMS quickly, generates imitative according to emulation signal message
The duration of true signal is substantially reduced.For example, the duration for generating resistance signal is about 500 μ s, and can be with when voltage signal
The formation speed of 20V/ μ s carries out.
Based on this, during a concrete implementation, after executing S103 and generating emulation signal, so that it may with direct
It executes in S104 and emulation signal is sent to the step in BMS.
Alternatively, during another concrete implementation, it is contemplated that also wrapped in the corresponding test script of target detection use-case
It includes：The transmission condition of signal is emulated, at this point it is possible to before executing S104, detects whether the transmission condition for meeting emulation signal,
When detecting to meet the transmission condition of emulation signal, can just execute will emulate signal in S104 is sent to step in BMS.Or
S104 is not carried out when detecting to be unsatisfactory for the transmission condition of emulation signal in person, until meeting the transmission item of emulation signal
Part.
When the above-mentioned second way execute S104 when, emulate signal transmission condition can carry out according to actual needs it is pre-
If.For example, the moment can be preset as, when reaching a certain default at the time of, detects the transmission condition for meeting emulation signal, hold
The forwarding step of row S104；Alternatively, when at the time of if not up to this is default, the emulation signal of generation is not sent.Also, based on not
Same emulation signal, can be arranged different transmission conditions, no longer be repeated herein.
In the embodiment of the present invention, after executing S104, S105 can be sequentially executed, BMS is obtained and emulates signal in input
Status information later.It is understood that the difference based on each candidate test case, the status information of the BMS of acquisition also may be used
With difference, alternatively, can also be identical, it is preset according to actual needs during actually realizing this programme, the present invention is real
Example is applied to this without being particularly limited to.
Based on the status information of the BMS got in S105, the test result of this BMS can be obtained, therefore, in reality
In application process, the test result of the BMS can also be exported.
The test result of output can there are many manifestation modes, for example, survey can be exported in the form of exporting test report
Test result.During a concrete implementation, test report can be generated, and export according to emulation signal and status information
The test report.It can include but is not limited in the test report：Test process, emulation signal, BMS input emulation signal it
At least one of status information and conclusion afterwards.The embodiment of the present invention for test report specific format without especially limiting
It is fixed, for example, can be the test report of XML format, or, or the test report of html format.
The technical solution of the embodiment of the present invention has the advantages that：
In the embodiment of the present invention, it can be instructed in response to test, automatically obtain target detection use-case and its corresponding survey
Training sheet, and run the test script and generate emulation signal, and the emulation signal of generation is inputed into BMS automatically, it should based on this
Emulate test of the signal realization to BMS；In this process, it is no longer necessary to which emulation signal is intended and inputted to user hand dynamic model, with target
The corresponding test script of test case with automatic running and can obtain test result, human cost be saved, when saving test
It is long, improve testing efficiency, also, emulation signal is simulated and modulated manually due to not needing user, avoid due to
The relatively low problem of accuracy present in manual analog simulation signal, to which the accuracy for reducing emulation signal is relatively low to surveying
The adverse effect of test result improves the accuracy rate of test result.Based on this, technical solution energy that the embodiment of the present invention is provided
Enough solutions are wasted by manpower caused by the manual analog simulation signal of tester in the prior art and testing efficiency is lower asks
