After the network testing device is built, the network testing method in the embodiment of the invention can be executed by the network testing device, and the method is applied to a network architecture of a vehicle. In an embodiment of the present invention, a network architecture of a vehicle includes N network segments, each network segment includes at least two network nodes, and N is an integer greater than or equal to 1. Currently, the network architecture of the vehicle may support one network protocol, and generally the network architecture of the vehicle supports two or more network protocols, e.g., an ethernet communication protocol, a CAN communication protocol, a LIN communication protocol, etc., and thus, the network architecture of the vehicle may include at least one of an ethernet network segment, a CAN network segment, and a LIN network segment. Furthermore, with respect to the same network communication protocol, the network architecture may also include multiple, parallel network segments, for example, the network architecture may include an ethernet segment, a CAN1 network segment, a CAN2 network segment, a LIN network segment. Each network segment includes at least two network nodes, and a network node of the network architecture may include a plurality of ECUs (Electronic Control units) and GWs (GateWay), where the GW may simultaneously connect different network segments, for example, the GW simultaneously connects an ethernet segment and a CAN network segment. The ECU may also be connected to different network segments simultaneously.
Fig. 3 shows a schematic structural diagram of a network architecture of a vehicle. As shown in fig. 3, the network architecture includes 13 ECUs, ECU1 to ECU13, wherein ECU1 belongs to the ethernet network segment, ECU2 to ECU6 belong to the CAN1 network segment, ECU7 to ECU9 belong to the CAN2 network segment, and ECU10 to ECU13 belong to the LIN network segment. In addition, the network architecture also includes a GW that connects the ethernet segment, the CAN1 network segment, and the CAN2 network segment.
The embodiment of the invention mainly comprises two aspects of network sleep test and network awakening test for the network architecture of the vehicle. For the convenience of understanding, the following specifically describes the technical solutions of the above two tests based on the network architecture of the vehicle shown in fig. 3 (hereinafter referred to as "network architecture").
The first embodiment is as follows: and (5) network sleep test.
As shown in fig. 4, the network testing method includes:
step 401: the parameters of the non-test network nodes in the test network segment are set to satisfy the sleep condition.
The test network segment is a network segment in a network architecture, that is, the test network segment is a network segment of N network segments, and the test network segment can be understood as a network segment which needs to be tested currently. If the network architecture includes a plurality of network segments, that is, if N is greater than 1, then the network segment that does not need to be tested currently among the N network segments may be understood as a non-test network segment.
Correspondingly, the non-test network node is one or more network nodes in the test network segment, the non-test network node may be understood as a network node which does not need to be tested currently in the test network segment, and the network node which needs to be tested currently in the test network segment may be understood as a test network node.
Step 402: setting parameters of a test network node in the test network segment to satisfy a sleep condition after a non-test network node in the test network segment is in a sleep state.
Step 403: and monitoring the network state of the test network node in the test network segment according to the network communication protocol of the test network segment.
In the embodiment of the invention, the network sleep test can be carried out on any network segment of the network architecture, namely, any network segment of the network architecture can be used as a test network segment to carry out the network sleep test. Since each network segment comprises at least two network nodes, the test network segment also comprises at least two network nodes. Therefore, when performing a network sleep test on a test network segment, the embodiment of the present invention provides the following test strategies: the network state detection method comprises the steps of meeting the sleep condition of non-test network nodes in a test network segment, meeting the sleep condition of the test network nodes in the test network segment after the non-test network nodes are in the sleep state, and then detecting the network state of the test network nodes in the test network segment according to a network communication protocol of the test network segment. And the test network node in the test network segment is any network node in the test network segment.
In the embodiment of the present invention, when the network architecture only includes 1 network segment, the test policy may be directly adopted. When the network architecture includes a plurality of network segments, that is, when N is greater than 1, a network sleep test is performed on a test network segment of the network architecture, the embodiment of the present invention further provides the following test strategy: the method comprises the steps of meeting the sleep condition of a non-test network section of a network architecture, meeting the sleep condition of a non-test network node in a test network section after the non-test network section is in a sleep state, and meeting the sleep condition of a test network node in the test network section after the non-test network node is in the sleep state. And then, detecting the network state of the test network node in the test network segment according to the network communication protocol of the test network segment.
That is, if N is greater than 1, before step 401, the method further includes:
setting parameters of non-test network segments of the N network segments to meet a sleep condition;
step 401 comprises:
setting parameters of non-test network nodes in the test network segment to satisfy a sleep condition after the non-test network segment is in a sleep state.
In this embodiment, if the test network node in the test network segment enters the sleep state, that is, the network state of the test network node in the test network segment is the sleep state, it indicates that the sleep test of the test network segment of the network architecture meets the requirement, and if the test network node in the test network segment does not enter the sleep state, it indicates that the sleep test of the test network segment of the network architecture does not meet the requirement.
For example, when a network sleep test needs to be performed on an ethernet segment of a network architecture, a network test device is connected to the ethernet segment, input and output types of channels of an I/O module are configured through a Panel test input window, a program-controlled power supply output is controlled through a CAPL test script, sleep conditions of a CAN1 network segment, a CAN2 network segment and a LIN network segment are met first, the sleep conditions of the ethernet segment are met finally, and then the sleep state of the ethernet segment is monitored through an ethernet channel of a CANoe according to an ethernet communication protocol. Because the network node of the Ethernet network section is the ECU1, and the test network node in the test network section can be the ECU1, the network test device is accessed to the ECU1, the input and output types of each channel of the I/O module are configured through a Panel test input window, the output of the program-controlled power supply is controlled through a CAPL test script, the sleep conditions of the ECUs 2 to 13 are met firstly, the sleep condition of the ECU1 is met finally, and then the sleep state of the ECU1 is monitored. Further, considering that the ethernet segment is also connected to the GW, in the embodiment of the present invention, in addition to monitoring the sleep state of the ECU1, the sleep state of the GW may be monitored.
For another example, when a network sleep test needs to be performed on a CAN1 network segment of a network architecture, the network test device is accessed to a CAN1 network segment, the input and output types of each channel of the I/O module are configured through a Panel test input window, the output of the program-controlled power supply is controlled through a CAPL test script, the sleep conditions of the ethernet network segment, the CAN2 network segment and the LIN network segment are met firstly, and finally the sleep conditions of the CAN1 network segment are met. Here, since the CAN1 network segment includes 5 ECUs in total from ECU2 to ECU6, when the parameters of the CAN1 network segment are set to satisfy the sleep condition, the parameters of each ECU in the CAN1 network segment may be set to satisfy the sleep condition in steps. In other words, when the test network segment includes a plurality of network nodes, the test network node in one test network segment may be determined first, when the parameter of the test network segment is set to satisfy the sleep condition, the parameter of the non-test network node in the test network segment is set to satisfy the sleep condition first, and finally the parameter of the test network node in the test network segment is set to satisfy the sleep condition.
Assuming that the ECU2 of the CAN1 network segment is determined as a test network node in the test network segment, the parameters of the ECUs 3 to 6 are first set to satisfy the sleep condition, and finally the parameters of the ECU2 are set to satisfy the sleep condition, and then the sleep states of the ECUs 2 and the ECUs 3 to the ECUs 6 are monitored through the CAN channels of the CANoe according to the CAN1 network communication protocol.
In the embodiment of the invention, under the condition that the test network section comprises a plurality of network nodes, each network node in the test network section is set to be under the sleep condition step by step, which is favorable for ensuring the stability of the test and further improving the accuracy of the test.
In the embodiment of the invention, the network sleep test is carried out on the network architecture, so that the automatic test of the network sleep of the network architecture is realized, the test efficiency is improved, the network test has the advantages of repeatability and higher consistency, and the test accuracy can be improved.
Example two: and (5) network wake-up testing.
As shown in fig. 5, the network testing method further includes:
step 501: and under the condition that all network nodes of the test network segment are in a sleep state, awakening the test network nodes in the test network segment.
And the test network node in the test network segment is any network node in the test network segment.
Step 502: and monitoring the network state of each network node in the test network segment according to the network communication protocol of the test network segment.
For example, when a network wakeup test needs to be performed on a CAN1 network segment of a network architecture, since the CAN1 network segment includes 5 ECUs from ECU2 to ECU6, a test network node in a test network segment CAN be selected from network nodes of CAN1, after all network nodes of the network segment to be tested sleep, the I/O module is controlled to wake up the test network node in the test network segment, and then, network states of ECU3 to ECU6 are respectively monitored according to a CAN1 network communication protocol.
In this embodiment, when the test network segment includes a plurality of network nodes, the test network node in the test network segment is first awakened in steps, and whether the non-test network nodes in the test network segment are awakened by the target network node is monitored, and if the non-test network nodes in the test network segment are all awakened, the entire test network segment is in an awakened state, so that on this basis, whether the non-test network segment of the network architecture is awakened is further monitored. Therefore, the step-by-step awakening mode is beneficial to ensuring the stability of the test, so that the test accuracy is further improved. When the network architecture has the condition of wakeup failure, each network node can be conveniently checked.
Optionally, the method further includes:
and if all the network nodes in the test network segment are awakened, determining that all the network nodes in the test network segment can be automatically awakened.
Correspondingly, if the network node which is not wakened exists in the test network segment, it is determined that the network node which is not wakened in the test network segment cannot be automatically waken, and it is indicated that the network wakening function of the network architecture has a problem.
Optionally, if N is greater than 1, after step 501, the method further includes:
and respectively monitoring the network states of the N network segments according to the network communication protocols of the N network segments.
For example, when the ethernet segments of the network architecture need to be subjected to the wake-on-lan test, after the whole vehicle is asleep, that is, under the condition that N network segments of the network architecture are in the sleep state, the control I/O module wakes up the ethernet segments, specifically, wakes up the ECU 1. Then, the network states of the CAN1 network segment, the CAN2 network segment, and the LIN network segment are monitored, respectively, according to the network communication protocol of each network segment. In addition, considering that the network architecture also includes a GW, in the embodiment of the present invention, in addition to monitoring the network states of the CAN1 network segment, the CAN2 network segment, and the LIN network segment, the network state of the GW may be monitored. Here, the monitoring of the network state of each network segment means monitoring whether each network segment is awakened normally. Thus, with the embodiment, it can be monitored whether the ethernet segment can wake up the non-test network segment when the ethernet segment is woken up, so as to test the network wakeup function of each network segment of the network architecture.
Optionally, the method further includes:
and if the N network segments are awakened, determining that each network segment of the network architecture can be automatically awakened.
Correspondingly, if the network architecture has the network segment which is not wakened, the fact that the network segment which is not wakened of the network architecture cannot be automatically wakened is determined, and the fact that the network wakening function of the network architecture has a problem is indicated.
It should be noted that, since the test network node in the test network segment is already woken up, and the network state of the test network node is in a woken-up state, the monitoring of the network state of each network node in the test network segment in step 502 may be to monitor the network state of a non-test network node in the test network segment, that is, the network state of the test network node in the test network segment may not be monitored any more in step 502.
Accordingly, the monitoring of the network states of the N network segments of the network architecture respectively may be monitoring of the network states of non-test network segments of the N network segments of the network architecture respectively, that is, the network states of the test network segments may not be monitored any more.
In the embodiment of the invention, the network sleep test is carried out on the network architecture, so that the network awakening automatic test of the network architecture is realized, the test efficiency is improved, the network test has the advantage of repeatability and higher consistency, and the test accuracy can be improved.
In addition, in the embodiment of the present invention, the network architecture may be subjected to the network sleep test first, and then the network architecture may be subjected to the wake-up test, that is, the step of waking up the test network node in the test network segment is performed after the step of setting the parameter of the test network node in the test network segment to satisfy the sleep condition.
Specifically, when N is equal to 1, the method comprises the following steps:
setting parameters of non-test network nodes in the test network segment to meet sleep conditions;
setting parameters of a test network node in the test network segment to meet a sleep condition after a non-test network node in the test network segment is in a sleep state;
monitoring the network state of a test network node in the test network segment according to the network communication protocol of the test network segment;
awakening the test network nodes in the test network segment under the condition that all network nodes of the test network segment are in a sleep state;
and monitoring the network state of each network node in the test network segment according to the network communication protocol of the test network segment.
Specifically, when N is greater than 1, the method comprises the following steps:
setting parameters of non-test network segments of the N network segments to meet a sleep condition;
setting parameters of non-test network nodes in the test network segment to satisfy a sleep condition after the non-test network segment is in a sleep state.
Setting parameters of a test network node in the test network segment to meet a sleep condition after a non-test network node in the test network segment is in a sleep state;
monitoring the network state of a test network node in the test network segment according to the network communication protocol of the test network segment;
awakening the test network nodes in the test network segment under the condition that all network nodes of the test network segment are in a sleep state;
monitoring the network state of each network node in the test network segment according to the network communication protocol of the test network segment;
and respectively monitoring the network states of the N network segments according to the network communication protocols of the N network segments.
For the network sleep test and the network wake-up test, reference may be made to the foregoing related descriptions, and details are not described herein to avoid repetition.
