[0042] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0043] On a truck production line, the chassis is configured with multiple circuits, such as a gas source circuit and an electrical circuit, which will affect the operation of the vehicle. Therefore, the chassis is an important component on the vehicle.

[0044] Currently, after the production of the chassis, it is generally directly used online. If there is a problem with at least one circuit of the chassis, the vehicle needs to be disassembled for troubleshooting and repair in the debugging area after being taken offline. If the circuit of the chassis can be tested after the production of the chassis, the chassis can be maintained in time to ensure the normal function of the chassis during use and avoid subsequent vehicle offline repair.

[0045] Therefore, how to test the circuit of the chassis is a technical problem that needs to be solved by those skilled in the art.

[0046] Currently, a fully assembled chassis can be powered on using a battery to test whether the main light is problematic. However, this test degree is low and cannot completely test the chassis circuit.

[0047] To this end, the application provides a chassis function test method and device, test requirement information of a target chassis is acquired, and a control instruction corresponding to the test requirement information is output to a target controlled device corresponding to the test requirement information, a specified parameter is collected, if the specified parameter meets a parameter fault rule, a display device in the chassis function test device is controlled to perform a chassis loop fault display operation corresponding to the specified parameter.

[0048] On the basis of the above, the application provides a chassis function test method applied to a test controller in a chassis function test device. Figures 1-4 The composition structure of the chassis function test device is introduced.

[0049] Specifically, the chassis function test device comprises a ground following mechanism 12, a test controller 111, a gas source generating component 112, a display device 13 and a server 14, the test controller 111 and the gas source generating component 112 can be arranged in a test host 11, and the specific structure can be referred to Figures 1-4 .

[0050] In actual application, since the feature of the work station of the chassis assembly is that the whole assembly process needs about 15 to 25 minutes from the beginning to the offline, the time of single function test and system reciprocation is relatively sufficient. Therefore, in the embodiment, the chassis can be tested when it is transported on the production line.

[0051] As shown in Figure 2 , the ground following mechanism 12 is used to control the synchronous motion of the chassis function test device and the target chassis, such as a truck chassis assembly 00. Figure 2

[0052] Specifically, the automatic following system function of the ground following mechanism 12 in the chassis function test device is to drive the test host to reciprocate on the production line by a motor through a ground rail, and the speed is synchronized with the production line.

[0053] The truck chassis assembly 00 to be tested can be recognized by a sensor, such as a photoelectric sensor 02. Figure 3 Among them, the photoelectric sensor 02 has three, which are installed on a bracket 01, as shown in Figure 3 . The test controller 111 recognizes the truck chassis assembly 00 to be tested according to the installation position, so as to judge whether it is necessary to move synchronously with the truck chassis assembly 00.

[0054] ​If synchronization is needed, the test controller 111 controls the ground following mechanism to make the chassis function test device and the target chassis move synchronously. During the synchronous movement, the tester connects the test air pipe and cable (marked with 03) between the chassis function test device and the target chassis for subsequent testing.

[0055] The test controller 111 in the present application is mainly used to execute the whole chassis function test method. During the test acquisition, the test requirement information is acquired from the server 14 storing the test requirement information through the local area network 04, and the corresponding test is performed based on the test requirement information.

[0056] The gas source generating component 112 is mainly used to output gas with a preset pressure to the gas source circuit of the target chassis based on the control of the test controller 111 during the gas source circuit test of the target chassis, so as to verify whether the gas tightness of the gas source circuit is good.

[0057] The display device 13 is mainly used to perform the chassis circuit fault display operation corresponding to the specified parameters when the test controller 111 detects the fault of the gas source circuit or the electric circuit.

[0058] Based on the structure of the chassis function test device, the chassis function test method can include the following steps. Figure 5

[0059] S11, when it is determined that there is a target chassis that needs to be tested, the test requirement information of the target chassis is acquired, and the control instruction corresponding to the test requirement information is output to the target controlled device corresponding to the test requirement information.

[0060] In actual application, the target chassis is the truck chassis assembly 00 to be tested, and the test requirement information of the target chassis is stored in the server 14. The test requirement information generally refers to the items to be tested, such as the test object and the test content.

[0061] The test controller 111 can acquire the test requirement information from the server 14 through the local area network 04, or the server 14 can send the test requirement information to the test controller 111 through the local area network 04.

[0062] It should be noted that in the present embodiment, the test requirement information of the target chassis is acquired only when the chassis function test device and the target chassis move synchronously and the chassis function test device is connected to the target chassis.

[0063] ​That is, during the process of controlling the chassis function test device to move synchronously with the target chassis, if the chassis function test device is connected with the target chassis, the test requirement information of the target chassis is acquired from the server 14 in the chassis function test device.

[0064] More specifically, the initial position of the chassis function test device is zero position, and whether there is a target chassis that needs to be tested can be determined in real time by the sensor in the chassis function test device, so as to determine whether there is a target chassis that needs to be tested. If so, the test requirement information of the target chassis is acquired. Specifically, the ground following mechanism 12 in the chassis function test device is controlled to act, so that the chassis function test device moves synchronously with the target chassis. And during the process of controlling the chassis function test device to move synchronously with the target chassis, if the chassis function test device is connected with the target chassis, the test requirement information of the target chassis is acquired from the server 14 in the chassis function test device; the test requirement information includes electrical circuit test requirement information and / or gas source circuit test requirement information.

[0065] In detail, the above-mentioned photoelectric sensor 02 can be used to detect whether there is a target chassis that needs to be tested on the production line, and if so, the test controller 111 controls the ground following mechanism 12 in the chassis function test device to act, so that the chassis function test device moves synchronously with the target chassis, that is, the running speed of the chassis function test device and the target chassis is the same.

[0066] During the synchronous movement of the two, the test personnel will connect the test gas pipe and cable (marked with 03) between the chassis function test device and the target chassis to perform subsequent tests.

[0067] During the test, the gas source circuit and the electrical circuit of the target chuck can be tested, and the target controlled equipment is different for different circuits. When the electrical circuit is tested, the target controlled equipment is the chassis controller, that is, the chassis controller is controlled to perform corresponding actions. When the gas source circuit is tested, the target controlled equipment is the above-mentioned gas source generating part 112, which controls the gas source generating part 112 to output gas with a preset pressure to the gas source circuit of the target chassis, so as to detect the sealing property of the gas source circuit of the target chuck.

[0068] S12, collecting specified parameters.

[0069] Among them, the specified parameters are parameters determined by the target controlled equipment corresponding to the test requirement information after the target controlled equipment responds to the control instruction.

[0070] In practical applications, the specified parameter can be determined by the chassis controller or the air source generating component 112 described above.

[0071] S13, if the specified parameter meets the parameter fault rule, controlling the display device 13 in the chassis function test device to perform the chassis loop fault display operation corresponding to the specified parameter.

[0072] Specifically, for the specified parameter, a corresponding parameter fault rule is configured for it. The parameter fault rule can be a preset parameter value or a judgment condition, which can be set according to the actual scene.

[0073] If yes, the specified parameter meets the parameter fault rule, which means that the corresponding loop is abnormal. At this time, the display device 13 performs a fault display operation on the loop, such as circling and flashing or flashing the entire loop. The flashing disappears after troubleshooting.

[0074] In this embodiment, the test requirement information of the target chassis is obtained, and the control instruction corresponding to the test requirement information is output to the target controlled device corresponding to the test requirement information. The specified parameter is collected. If the specified parameter meets the parameter fault rule, the display device 13 in the chassis function test device is controlled to perform the chassis loop fault display operation corresponding to the specified parameter. That is, the present application can test the chassis loop and perform fault display. Therefore, when the chassis loop fails, timely chassis maintenance can be performed, thereby ensuring the normal function of the chassis during use and avoiding subsequent vehicle off-line maintenance.

[0075] On the basis of the above embodiment, the specific implementation contents of steps S11-S13 are different in the case that the content of the test requirement information is different, which will be introduced respectively.

[0076] 1. In the case that the test requirement information is electrical loop test requirement information, "outputting the control instruction corresponding to the test requirement information to the target controlled device corresponding to the test requirement information" can include:

[0077] determining the control instruction corresponding to the electrical loop test requirement information and the chassis controller located on the target chassis and corresponding to the control instruction, and outputting the control instruction to the chassis controller.

[0078] Specifically, the test host 11 is configured with a test controller 111.

[0079] The chassis controller is a controller installed on the truck chassis assembly 00. In addition to being configured with the chassis controller, the truck chassis assembly 00 is also configured with a chassis actuator, such as a lamp.

[0080] In this embodiment, the test controller 111 outputs a control instruction, such as a driving signal, to the chassis controller. The driving signal is a high (or low) level input signal provided by the test controller 111 to the chassis controller. In theory, the test controller 111 determines whether the lamp circuit has a problem based on whether the chassis controller outputs a signal to the lamp.

[0081] At this time, the high level signal can be collected. If the high level signal, i.e., 24V, can be collected, it indicates that the chassis controller controls the lamp circuit normally. If the signal cannot be collected or a low level signal is collected, it indicates that the chassis controller controls the lamp circuit abnormally.

[0082] In this embodiment, collecting the specified parameter means:

[0083] Collecting an output parameter generated and output by the chassis controller to a chassis actuator corresponding to the control instruction in response to the control instruction.

[0084] In the case of testing whether the chassis controller controls the lamp switch and the lamp normally, the specified parameter is a level signal output by the test controller 111 to the lamp output pin, which is collected by the resource board card of the test host 11.

[0085] On the basis of this embodiment, if the specified parameter meets the parameter fault rule, the display device 13 in the chassis function test device is controlled to perform a chassis circuit fault display operation corresponding to the specified parameter, including:

[0086] If the parameter value of the output parameter is not the preset parameter value, the display device 13 in the chassis function test device is controlled to perform a fault display operation on the electrical circuit corresponding to the specified parameter.

[0087] In the case of testing whether the chassis controller controls the lamp switch and the lamp normally, if the level signal is high, i.e., when 24V output is collected, it is determined that the chassis controller controls the high beam switch normally. If 24V cannot be collected, it is determined that the chassis controller controls the high beam switch abnormally, i.e., the chassis controller controls the high beam switch circuit abnormally.

[0088] The display device 13 in the chassis function test device is a public display screen installed at the tail of the chassis test line. The operator can watch the relevant information at the test station position, which is mainly used to inform the operator of the fault area. The display mode is the layout of the entire chassis electrical circuit. If a single area has a problem, the area is circled and flashed. After the fault is eliminated, the flashing disappears. If a circuit has a problem, the circuit is flashed. After the fault is eliminated, the flashing disappears.

[0089] In this embodiment, if the chassis controller controls the abnormal electrical circuit of the headlamp switch, the display device 13 flashes the electrical circuit to remind the tester of the circuit failure.

[0090] As can be seen from the above, the test controller 111 generates control instructions, collects the signals fed back by the chassis controller, judges, and finally displays and prompts the verification result on the large screen of the display device 13. At the same time, the test result can also be saved in the server 14 in the chassis function test device.

[0091] 2. In the case of the test requirement information being the gas source circuit test requirement information, the "outputting the control instruction corresponding to the test requirement information to the target controlled device corresponding to the test requirement information" can include:

[0092] Outputting the gas source control instruction to the gas source generating component 112 in the chassis function test device, so that the gas source generating component 112 outputs the gas with the preset pressure to the gas source circuit of the target chassis.

[0093] Specifically, when verifying the air tightness of the gas source circuit of the target chassis, the gas source generating component 112 can be used to provide the gas source. The gas source generating component 112 can be understood as an integrated gas pump, which has the functions of generating gas and monitoring the gas pressure in real time.

[0094] The requirement for the air tightness verification of the gas source circuit of the chassis is that the gas source generating component 112 needs to provide a gas source of 0.3 MPa. In this embodiment, the test controller 111 can be used to control the pressure and on-off of the output gas of the gas source generating component 112, that is, the test controller 111 can control the pressurization and depressurization of the gas of the gas source generating component 112. When the test gas pipe is connected, the chassis is loaded with a gas pressure of 0.3-0.6 MPa, and when the test gas pipe is disconnected, the test controller 111 controls the rapid depressurization. For example, the test controller 111 can output the gas source control instruction to the gas source generating component 112 in the chassis function test device, so that the gas source generating component 112 outputs the gas with the preset pressure (0.3 MPa) to the gas source circuit of the target chassis.

[0095] Then, after a preset time, the internal gas path pressure of the gas source generating component 112 is collected. For example, after waiting for 2 minutes, the gas source generating component 112 collects the internal gas path pressure of itself and transmits it to the test controller 111.

[0096] If the internal gas path pressure is different from the preset pressure, the display device 13 in the chassis function test device is controlled to perform the fault display operation on the gas source circuit.

[0097] Specifically, if the pressure in the gas path generating component is still 0.3 MPa, it is determined that the gas path is airtight, otherwise, the airtightness is problematic and needs to be repaired. At this time, the gas source circuit can be flashed on the display device 13 to remind the tester that the gas source circuit is faulty.

[0098] In actual application, the test results of the airtightness of the target chassis passing or failing can be transmitted to the server 14 for storage. In addition, the final function test results of all functions in the present application are stored in the server 14, and the chassis order data of the associated test is bound for subsequent retrieval.

[0099] It should be noted that during the entire test process, the test controller 111 is always running until the tester disconnects the test gas pipe and cable (identified by 03) between the chassis function test device and the target chassis being tested, or until the chassis exceeds the final position of the test station, at which point the chassis function verification is stopped, and the chassis function test device will automatically return to the initial position, waiting for the next chassis. The operator can identify the assembly status of the entire machine according to the large screen of the display device 13 configured on the production line.

[0100] The embodiment fills the gap in chassis function test, realizes less manual intervention, and saves manpower. In addition, the test content of the embodiment is more comprehensive, providing quality control for chassis assembly.

[0101] Optionally, based on the embodiment of the above-mentioned chassis function test method, another embodiment of the present application provides a chassis function test device, which comprises a ground follow-up mechanism 12, a test controller 111, a gas source generating component 112, a display device 13, and a server 14.

[0105] The display device 13 is used to perform the chassis circuit fault display operation corresponding to the specified parameters;

[0106] The server 14 is used to store test requirement information.

That is, the chassis loop can be tested and fault display is performed, so that chassis maintenance can be performed in time when the chassis loop fails, and the function of the chassis during use is ensured to be normal, and subsequent vehicle off-line maintenance is avoided.
