[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] The embodiment of the present application provides a method for testing automobile power distribution protection to solve the problems that the existing test is manually performed by testers, the test time is long, the test efficiency is low, and the test results are likely to fail to meet the expected effects and the accuracy of the test results cannot be guaranteed.

[0045] In practical applications, the automotive power distribution protection test method can be applied to the host computer, see Figure 1 , the automobile power distribution protection test method mainly includes the following steps:

[0046] S101. Determine a power distribution channel test configuration table of a power distribution protection channel controller to be tested.

[0047] The power distribution channel test configuration table includes a plurality of power distribution channel test configuration arrays, and each power distribution channel test configuration array includes a test power distribution channel sequence number, a test current value, and a test expected shutdown time.

[0048] In practical applications, the power distribution protection channel controller to be tested is a power distribution protection channel controller in a car that needs to be tested for power distribution protection but has not yet been tested. A power distribution protection channel controller is generally provided with multiple power distribution channels, each of which is composed of a corresponding electronic fuse.

[0049] In some embodiments, the specific process of executing step S101 and determining the distribution channel test configuration table of the distribution protection channel controller to be tested can be as follows: Figure 2 As shown, it mainly includes steps S201 and S202:

[0050] S201. Determine a test configuration array for each power distribution channel of a power distribution protection channel controller to be tested.

[0051] In practical applications, each distribution channel test configuration array includes relevant parameters required to perform a test on a distribution channel of the distribution protection channel controller to be tested, including at least the test distribution channel sequence number, the test current value and the test expected shutdown time.

[0052] Among them, the test current value is the current value required when testing the distribution channel corresponding to the test distribution channel number, and the test expected shutdown time is the time when the distribution channel corresponding to the test distribution channel number is expected to be shut down when testing.

[0053] Since there are multiple distribution channels in the distribution protection channel controller to be tested, in order to facilitate the host computer to determine the distribution channel to be tested when executing the test, each distribution channel can be numbered separately, that is, each distribution channel has a unique test distribution channel serial number.

[0054] After the distribution channel to be tested is determined, the test current and the expected test shutdown time can be determined in combination with the working conditions that the test channel needs to test. The test distribution channel number of the distribution channel to be tested, the test current determined according to the working conditions that need to be tested, and the expected test shutdown time are used as a distribution channel test configuration array.

[0055] It should be noted that the test current and expected shutdown time are different for different working conditions. In practice, three working condition tests can be performed for each distribution channel, such as less than the rated current, equal to the rated current, and greater than the rated current. Among them, under the condition of greater than the rated current, the test current can be configured according to the test requirements, such as 110% of the rated current and 130% of the rated current.

[0056] It should also be noted that the test current value and the test expected shutdown time in the distribution channel test configuration array can also be adjusted in combination with the load of the distribution protection channel controller to be tested and the size of the wire diameter of the connecting wire harness.

[0057] S202. Integrate all the power distribution channel test configuration arrays in order to obtain a power distribution channel test configuration table of the power distribution protection channel controller to be tested.

[0058] In practical applications, after determining each distribution channel test configuration array of the distribution protection channel controller to be tested, all distribution channel test configuration arrays can be integrated according to a preset test sequence to obtain a distribution channel test configuration table of the distribution protection channel controller to be tested.

[0059] Among them, the preset test order can be determined according to the application environment and user needs, such as sorting by the test distribution channel number, or sorting by the test current value, or sorting by the test expected shutdown time. This application does not limit it and it is within the protection scope of this application.

[0060] S102: Determine the actual test shutdown time corresponding to each power distribution channel test configuration array in the power distribution channel test configuration table.

[0061] In practical applications, the distribution protection channel controller to be tested is tested according to each distribution channel test configuration array in the distribution channel test configuration table, and the actual test shutdown time corresponding to each distribution channel test configuration array can be obtained.

[0062] In some embodiments, the specific process of executing step S102 and determining the actual test shutdown time corresponding to each power distribution channel test configuration array in the power distribution channel test configuration table can be as follows: Figure 3 As shown, it mainly includes steps S301 and S302:

[0063] S301. Determine the test order of each power distribution channel test configuration array in the power distribution channel test configuration table.

[0064] In practical applications, since each distribution channel test configuration array in the distribution channel test configuration table is integrated in a certain order, the host computer can determine the test order of each distribution channel test configuration array according to the order of each distribution channel test configuration array in the distribution channel test configuration table.

[0065] S302 , testing the power distribution protection channel controllers to be tested in sequence according to the test sequence, and obtaining the actual test shutdown time corresponding to each power distribution channel test configuration array.

[0066] In actual applications, after determining the test order of each distribution channel test configuration array in the distribution channel test configuration table, the host computer can test the distribution protection channel controller to be tested in sequence according to the test order to obtain the actual test shutdown time corresponding to each distribution channel test configuration array.

[0067] For example, the distribution channel test configuration table may be as shown in Table 1-1:

[0068] Table 1-1

[0069] Test power distribution channel number Test current value Test expected off time 1 11A 5s 2 11A 5s 3 11A 5s …… …… …… 1 13A 2.5s 2 13A 2.5s 3 13A 2.5s …… …… ……

[0070] In some embodiments, the specific process of testing the distribution protection channel controller to be tested and obtaining the actual test shutdown time corresponding to each distribution channel test configuration array mainly includes steps S401 and S402:

[0071] S401. For each distribution channel test configuration array, control the relay switch of the distribution channel corresponding to the test distribution channel number of the distribution channel test configuration array in the distribution protection channel controller to be tested to turn on, and the electronic load outputs the test current value of the distribution channel test configuration array.

[0072] In actual applications, the distribution protection channel controller to be tested is connected to the electronic load through a relay switch. Specifically, each distribution channel in the distribution protection channel controller to be tested is connected to the electronic load through a corresponding relay switch, and the relay switch of the distribution channel corresponding to the test distribution channel number of the distribution channel test configuration array is controlled to be turned on, so that the current value output by the electronic load can directly act on the current distribution channel to be tested of the distribution protection channel controller to be tested, that is, the test current value output by the electronic load can enter the corresponding distribution channel to implement the test.

[0073] S402: Monitor the output current value of the electronic load to obtain the actual test shutdown time corresponding to each power distribution channel test configuration array.

[0074] In practical applications, the output current value of the electronic load can be monitored by the host computer to determine the actual test shutdown time corresponding to each distribution channel test configuration array through the monitoring data.

[0075] In some embodiments, the specific process of executing step S402, monitoring the output current value of the electronic load, and obtaining the actual test shutdown time corresponding to each power distribution channel test configuration array mainly includes steps S501 and S502:

[0076] S501 , respectively monitor a first test time point and a second test time point corresponding to each power distribution channel test configuration array.

[0077] Among them, the first test time point is the time point when the output current value of the electronic load reaches the test current value, and the second test time point is the time point when the output current value of the electronic load becomes zero or is less than the test current value. The first test time point is earlier than the second test time point.

[0078] In practical applications, during the testing of each distribution channel test configuration array, the output current value of the electronic load can be monitored in real time by the host computer to obtain the first test time point and the second test time point corresponding to each distribution channel test configuration array.

[0079] S502 , for each power distribution channel test configuration array, perform calculations based on the first test time point and the second test time point corresponding to the array to obtain the actual test shutdown time corresponding to each power distribution channel test configuration array.

[0080] For each power distribution channel test configuration array, the first test time point may be subtracted from the second test time point corresponding thereto, thereby obtaining the actual test shutdown time corresponding to each power distribution channel test configuration array.

[0081] The output current value of the electronic load is related to the conduction state of the distribution channel corresponding to the test distribution channel number in the distribution channel test configuration array. Only when the distribution channel corresponding to the test distribution channel number in the distribution channel test configuration array is in a fully conducted state, the output current value of the electronic load will be output according to the test current value of the distribution channel test configuration array. When the distribution channel corresponding to the test distribution channel number in the distribution channel test configuration array is not fully conducted, the output current value of the electronic load cannot reach the test current value of the distribution channel test configuration array. When the distribution channel corresponding to the test distribution channel number in the distribution channel test configuration array is in a disconnected state, the output current value of the electronic load will drop to zero. Therefore, the duration that the output current value of the electronic load meets the test current value of the distribution channel test configuration array is the actual shutdown time of the test.

[0082] It should be noted that since it takes a certain amount of time for the current value output by the electronic load to become zero, in actual applications, the test result obtained by taking the time point when the output current value of the electronic load is less than the test current value as the second test time point is more accurate than the time point when the output current value of the electronic load becomes zero.

[0083] S103, respectively compare the expected test shutdown time in each power distribution channel test configuration array with the corresponding actual test shutdown time to obtain a power distribution channel test result of the power distribution protection channel controller to be tested.

[0084] In practical applications, the distribution channel test result of the distribution protection channel controller to be tested can be obtained according to the test expected shutdown time of the distribution channel test configuration array corresponding to each distribution channel and the corresponding test actual shutdown time.

[0085] In some embodiments, the specific process of executing step S103, comparing the expected test shutdown time in each distribution channel test configuration array with the corresponding actual test shutdown time, and obtaining the distribution channel test result of the distribution protection channel controller to be tested includes steps S601 and S602:

[0086] S601 , respectively determine whether the expected shutdown time of each power distribution channel test configuration array is greater than the corresponding actual shutdown time of the test.

[0087] In actual applications, after the upper computer tests each distribution channel test configuration array, the actual test shutdown time corresponding to each distribution channel test configuration array can be stored. After completing the test of all distribution channel test configuration arrays in the distribution channel test configuration table, it is determined whether the expected test shutdown time in each distribution channel test configuration array is greater than the corresponding actual test shutdown time.

[0088] S602. The distribution channel test result corresponding to the distribution channel test configuration array whose expected test shutdown time is greater than the corresponding actual test shutdown time is recorded as effective protection, and the distribution channel test result corresponding to the distribution channel test configuration array whose expected test shutdown time is less than the corresponding actual test shutdown time is recorded as failed protection.

[0089] In practical applications, the distribution channel test results of the distribution protection channel controller to be tested can be divided into protection validity and protection failure. For each distribution channel test configuration array, the distribution channel test result corresponding to the distribution channel test configuration array whose expected test shutdown time is greater than the corresponding actual test shutdown time can be recorded as protection validity, and the distribution channel test result corresponding to the distribution channel test configuration array whose expected test shutdown time is less than the corresponding actual test shutdown time can be recorded as protection failure.

[0090] Based on the above principles, the automobile power distribution protection test method provided in this embodiment can be applied to a host computer, and the method includes: determining a power distribution channel test configuration table of a power distribution protection channel controller to be tested, the power distribution channel test configuration table including multiple power distribution channel test configuration arrays, each power distribution channel test configuration array including a test power distribution channel serial number, a test current value and a test expected shutdown time; determining the test actual shutdown time corresponding to each distribution channel test configuration array in the power distribution channel test configuration table; respectively comparing the test expected shutdown time in each distribution channel test configuration array with the corresponding test actual shutdown time to obtain a power distribution channel test result of the power distribution protection channel controller to be tested, and testing the power distribution protection channel controller to be tested by the host computer according to the power distribution channel test configuration table of the power distribution protection channel controller to be tested, thereby solving the problem that the existing test is manually implemented by testers, the test time is long, and it is easy to cause the test results to not meet the expected effect, and the accuracy of the test results cannot be guaranteed.

[0091] It is worth noting that since the present application tests the power distribution protection channel controller to be tested through a host computer, compared with the existing manual testing by testers, it can also reduce the risk of testers contacting electrical circuits. Since the test is performed by a machine, electric shock and other potential risks are also reduced.

[0092] Optionally, in another embodiment provided in this application, see Figure 4After executing step S103, respectively comparing the expected test shutdown time in each power distribution channel test configuration array with the corresponding actual test shutdown time, and obtaining the power distribution channel test result of the power distribution protection channel controller to be tested, the automobile power distribution protection test method may further include step S701:

[0094] In practical applications, the test results of the distribution channels marked as protection failures may be recorded as abnormal results in the test report.

[0095] In this embodiment, after the distribution channel test result of the distribution protection channel controller to be tested is obtained, a test report can be generated based on the distribution channel test result of the distribution protection channel controller to be tested for reference by relevant personnel.

[0096] Optionally, another embodiment of the present application further provides an automotive power distribution protection test system, see Figure 5 ,The automobile power distribution protection test system mainly includes: a program-controlled power supply, a relay switch, an electronic load, a power distribution protection channel controller to be tested and a host computer;

[0100] The host computer is connected to the electronic load and the relay switch via a communication harness, so as to execute the automobile power distribution protection test method as described in any of the above embodiments.

[0101] In practical applications, the host computer can automatically execute the automotive power distribution protection test method, use the electronic load to simulate the real load overcurrent condition for each distribution channel in the power distribution protection channel controller to be tested, verify whether the overcurrent protection strategy works, obtain the distribution channel test results of the power distribution protection channel controller to be tested, and generate a test report, which can improve the test speed and accuracy and maintain the consistency of the test data.
