[0045] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0046] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. The words "including" or "comprising" and the like used in the embodiments of the present disclosure mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. The words "connected" or "connected" and the like are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0047] With the advent of the era of software-defined cars, the automotive industry has undergone earth-shaking changes, covering automotive development, development tools, sales models, etc. It is precisely because of this that the AUTOSAR development tool has been favored and recognized by many car companies since its appearance, and this is just a microcosm of the changes in the automotive industry.

[0048] AUTOSAR Network Management (AUTOSAR NM) is the network management mechanism in the AUTOSAR system. The AUTOSAR network management module of the automotive electronic control unit (EUC) controls the sleep and wake-up of individual components and the entire vehicle. Figure 1 As shown, the states of the Autosar network management state machine mainly include bus-sleep mode, prepare bus-sleep mode and network mode; among them, the network mode includes three sub-states, namely repeat message state (Repeat Message State, abbreviated RMS), normal operation state (Normal Operation State, abbreviated NOS) and ready sleep state (Ready-Sleep State, abbreviated RSS).

[0049] Furthermore, sleep mode is what we call hibernation. When the ECU has no local network wake-up source and remote wake-up request source, the controller will enter this sleep mode. In this state, the ECU is in a low-power state, most power-consuming peripherals are turned off, and only some wake-up source detections are left. In this mode, network management messages are only received but not sent, and application messages are neither received nor sent.

[0050] From the literal meaning of pre-sleep mode, we can know that this is a state of preparing to enter sleep. Application messages are neither sent nor received, and network management messages are only received but not sent. When the ECU enters this state, it is in a state of only receiving NM frames. It will wait for a period of time T_WAIT_BUS_SLEEP to allow all ECUs in the vehicle to sleep together. When T_WAIT_BUS_SLEEP times out, it enters sleep mode.

[0051] The repeated message state (RMS) includes two states: NM PDU Normal immediate state and NM PDU Normal Transmit State. The NM PDU Normal immediate state is mainly when the ECU is the main wake-up node. When it detects a local wake-up source (such as switch detection / Bluetooth connection / NFC card proximity and other wake-up conditions), it will first wake up from the vehicle network. At this time, it will send several NM frames in a fast cycle (for example, 5 times in a 10ms cycle) to quickly notify other ECUs that it has "come online" and is ready to communicate on the network. After the fast sending is completed, it enters the NM PDU Normal Transmit State state, and at this time, the NM message is sent in a normal cycle.

[0052] Normal working state (NOS), when the ECU enters RMS for a period of time, it will jump to the normal working state. In this state, NM messages can be received and sent, and application messages (abbreviated as APP messages) can be received and sent. NOS can indicate that the ECU is in a real wake-up state and can communicate normally.

[0053] Ready to sleep state (RSS), when the ECU is ready to enter sleep from working state, it must go through this state, mainly to do some preparations before sleep, for example, some data to be stored in EEPROM is still in writing operation, ESCL electronic steering column lock unlocking action has not been completed, or the motor controller may detect that the motor is not in the stopped state. In other words, this state is to complete the preparations before sleep, that is, the peripherals of the ECU must be in idle state. In RSS state, NM messages can only be received but not sent, while APP messages can be received and sent.

[0054] At present, there is still a lack of systematic and efficient testing methods for the verification of Autosar network management mechanisms. The network management wake-up nodes of different ECUs are different, and test cases and test scripts need to be redeveloped for the above five different states, resulting in long testing time, heavy workload, low work efficiency and easy errors.

[0055] In view of this, our company provides a testing method based on the Autosar network management mechanism to achieve efficient automated testing based on the Autosar network management mechanism.

[0056] Combine the following Figure 2 The flowchart of is used to describe the test method for implementing automated testing provided by the exemplary embodiment of the present disclosure. Specifically, the test method shown includes:

[0057] Step 201: Obtain the state transition mode to be tested and the network management message ID corresponding to the electronic control unit to be tested.

[0058] Exemplarily, the state transition mode to be tested may be from the repeat message state (RMS) to the normal working state (NOS), and from the normal working state (NOS) to the ready to sleep state (RSS), which are not listed here one by one.

[0059] Here, the state transition mode to be tested and the network management message ID can be obtained by means of an input device, which includes but is not limited to a touch screen, a keyboard, a voice input device or other electronic devices capable of realizing the above functions.

[0060] It should be noted that the corresponding network management message ID includes a sent (Tx) network management message ID and a received (Rx) network management message ID.

[0061] Step 202: According to the state transition mode to be tested and the network management message ID, a preset test case is matched and updated.

[0062] It should be noted that for different state transition modes, corresponding test cases can be developed to form preset test cases, and multiple test cases constitute a test case library (see Figure 5 ).

[0063] Optionally, the test case library is developed based on the Specification of CAN Network Management AUTOSAR to meet the testing needs of the automotive electronic control unit network management module.

[0064] In some embodiments, according to the state transition mode to be tested, a preset test case is matched in a pre-developed test case library. Further, the preset test case is updated using the network management message ID.

[0065] Those skilled in the art can understand that by using preset test cases, this process does not require human intervention and can quickly and easily refine the test items for subsequent execution.

[0066] Step 203: Execute the updated test case.

[0067] Here, executing the updated test case includes sending / receiving a network management message to the electronic control unit to be tested. It should be understood that the specific execution content includes but is not limited to the aforementioned network management message.

[0068] Step 204: Acquire test data, determine the test result according to the preset network management status flag and the test data, and output it;

[0069] Wherein, the preset network management state flag bit matches the state transition mode to be tested;

[0070] The network management status flag includes at least one preset flag item and its preset status information.

[0071] It should be noted that, taking the AUTOSAR network management specification as an example, corresponding to different network management states, there are differences in the sending and receiving states of network management messages and application messages and / or the current state of the power bus. Therefore, the embodiment of the present disclosure predefines a network management state flag bit for each network management state, so as to automatically process the test data and directly output the test results.

[0072] It can be seen from the above embodiments that it is only necessary to determine the state transition mode to be tested and the network management message ID corresponding to the electronic control unit to be tested, so that the preset test case can be determined and updated, without the need to manually change the parameter configuration, which is quick and convenient; using the preset network management state flag and test data, the test results can be directly obtained without manual analysis, saving time, and ultimately achieving automatic testing of the Autosar network management mechanism, which greatly ensures the reliability of the state transition test of the electronic control component while improving the test efficiency.

[0073] Based on the testing method disclosed in the present invention, the tester only needs to input the state transition mode and the network management message ID corresponding to the electronic control unit to implement the state test of the electronic control unit, which facilitates the efficient testing of multiple state transition modules and multiple electronic control units, saving time for automobile design.

[0074] Optionally, the test results include test failure and test success. Correspondingly, a success report is output based on test success; a failure report is output based on test failure. Optionally, the failure report includes a failure flag item and its corresponding status information, as well as preset status information. Such a test includes, which is conducive to the tester to centrally analyze the test failure content, and improves the test efficiency and reliability of the network management status of the electronic control element.

[0075] In some embodiments, Figure 3As shown, the step of determining and outputting the test result according to the preset network management status flag and the test data specifically includes:

[0076] Step 301: Based on the preset flag item, the test data is processed to obtain test status information.

[0077] It should be noted that after executing the updated test case, the test data obtained includes multiple items, such as bus current, application message, and NM message. For the status of a certain network management, it is only necessary to judge the flag item without judging the non-flag item (see Table 1), and there is no need to parse it in detail, such as parsing the timestamp of the non-flag item. Therefore, processing the test data using the preset flag item can effectively reduce the complexity of the following comparison step 302 and improve the comparison efficiency.

[0078] Step 302: Compare the test status information with the preset status information.

[0079] Step 303: If each of the test status information matches the preset status information, the test is successful; otherwise, the test fails.

[0080] For example, for the Ready-Sleep State (RSS), the preset flag items include sending application messages and sending network messages (see Table 1). If the states of sending application messages and sending network messages both meet the corresponding preset state information, the electronic control element is in the Ready-Sleep State and the test is successful. If either or both do not meet the corresponding preset state information, the test fails.

[0081] This test data processing method eliminates the need for manual intervention, saves manpower, and helps improve the efficiency and accuracy of result judgment.

[0082] In some embodiments, see Figure 4 The step of processing the test data based on the preset flag item to obtain the test status information includes:

[0083] Step 401: Based on the preset flag item, the test data is filtered to obtain test flag data.

[0084] Here, the data removed by filtering includes but is not limited to the data corresponding to the non-flag items (please refer to Table 1), which can effectively reduce the workload of subsequent data analysis and improve work efficiency.

[0085] Step 402: Based on the test mark data, obtain the test status information.

[0086] Exemplarily, for the sleep-ready state, the test flag item data includes the sending status of the application message and the sending status of the network management message. If the application message is sent, the test status information is satisfied; if the application message is not sent, the test status information is not satisfied. If the network management message is sent, the test status information is satisfied; if the network management message is not sent, the test status information is not satisfied.

[0087] Therefore, by adopting the technical solution of the present disclosure, the test status information can be conveniently compared with the preset status information, which is efficient and convenient.

[0088] In some embodiments, the testing method further comprises:

[0089] According to the state transition mode to be tested and the preset network management state flag library (see Figure 5 ), determine the preset network management status flag; wherein the preset network management status flag library includes at least one network management state and its corresponding network management status flag.

[0090] It should be understood that each network management state corresponds to a network management state flag. Based on the state of the state transition mode to be tested, the corresponding network management state flag can be determined from a preset network management state flag library. It should be understood that the network management state flag includes at least one network management state flag item.

[0091] Optionally, the preset network management status flag library is determined based on the Autosar network management specification. Referring to Table 1, the embodiment of the present disclosure provides a network management status flag library determined based on the Autosar network management specification.

[0092] Table 1 Network management status flag library determined based on Autosar network management specification

[0093]

[0094] Note: satisfy

[0095] ○: Not satisfied

[0096] -: The current mode is not judged, that is, it is a non-flag item.

[0097] It should be understood that the test data filtered out in step 401 is data corresponding to the non-flag items of the current mode in the above table.

[0098] The specific specifications of the NM Timeout Timer and Repeat Message Timer in the above table can be determined according to design requirements, such as 1 minute, and are not specifically limited here.

[0099] Exemplarily, the flag bit of Prepare Bus-Sleep Mode includes three flag items, one of which is NMTimeoutTimer expiration, and the corresponding preset status information is satisfied. That is to say, the embodiment of the present disclosure does not focus on the specific specification of NMTimeout Timer, but only focuses on whether NM TimeoutTimer expiration is satisfied.

[0100] Optionally, the test method can be used for network management mode conversion testing, and can also be used for regression testing of a certain failed network management state based on previous test results. The present disclosure does not specifically limit the application scenario of the test method.

[0101] It should be noted that the method of the embodiment of the present disclosure can be performed by a single device, such as the bus acquisition simulation tool VN1640A. The method of this embodiment can also be applied to a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of the embodiment of the present disclosure, and the multiple devices will interact with each other to complete the described method.

[0102] It should be noted that the above describes some embodiments of the present disclosure. Other embodiments are within the scope of the appended claims.
