Among them, in response to the actual testing and application requirements of vehicles, it is necessary to quickly build a chassis domain test bench to complete the external load test of the controller in order to test the performance of the chassis domain controller. For example: inductive load test, capacitive load test, linear impedance load test, and other combined load tests.

[0003] Generally speaking, the common test method is to use physical loads for testing. This method can simulate actual working conditions. However, in most cases, physical loads are heavy, difficult to move and place, and do not have the attribute of portability. Especially when testing and verifying in different places, it will increase the time cost, transportation cost and space cost of testing. At present, the testing and verification of chassis domain controllers using real loads have problems such as large volume, difficult handling, high transportation cost, and high replacement cost.

[0043] As described in the background art, the common test method is to use a physical load for testing. This method can simulate the actual working conditions. However, in most cases, the physical load is heavy, difficult to move and place, and does not have the portability attribute. Especially when testing and verifying in different places, it will increase the time cost, transportation cost and space cost of the test. At present, the chassis domain controller test and verification uses a real load, which has problems such as large volume, difficult to carry, high transportation cost, and high replacement cost.

[0044] In addition, it is also possible to use a simulated load for testing. This method can also simulate the actual working conditions to a large extent, and has a small volume and certain portability. However, this device is generally a customized product, with poor versatility and expandability.

[0045] In view of the above technical problems, the embodiments of the present application provide an analog load test device for a chassis domain controller and a vehicle. The analog load test device for a chassis domain controller provided in the first aspect of the embodiments of the present application includes a load simulation group, which is used to simulate the loads connected to the chassis domain controller. The load simulation group includes at least one functional module and a connection component. The functional module includes: a module body, which has a receiving cavity, and the module body has a first interface in a first direction and a functional interface in a direction different from the first direction. The connection component is connected to the functional interface; a path component, which is located in the receiving cavity. The path component includes a connection path and a functional path. Both the functional path and the connection path have a first connector located at the first interface and a functional connector located at the functional interface. The first connector of one functional module is used to be electrically connected to the chassis domain controller, and the functional connector is used to simulate one of the loads connected to the chassis domain controller by connecting one or more functional modules through the connection component; an electronic module, which is located in the receiving cavity and is connected to the functional path. In this way, the analog load test device for a chassis domain controller provided in the embodiments of the present application is connected to the chassis domain controller to implement the performance test of the chassis domain controller. It has a small volume and is easy to carry, and can simulate the actual working conditions to a certain extent.

[0046] The second aspect of the present application provides a vehicle, which includes a chassis domain controller. Among them, the chassis domain controller is connected to the above-mentioned analog load test device for a chassis domain controller to implement the load test.

[0047] The following will illustrate the implementation manners of the present application with reference to the drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in this specification. The present application can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for explaining the present application, rather than for limiting the protection scope of the present application.

[0048] It should be noted that the drawings provided in the following embodiments only illustrate the basic concept of the present application in a schematic manner. Therefore, the drawings only show the components related to the present application, rather than being drawn according to the number, shape and size of the components in actual implementation. The type, quantity and proportion of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0049] The embodiments of the present application provide a simulation load test device for a chassis domain controller and a vehicle. By setting at least one functional module, a connection component, and a path component, a simulation load structure is built. The functional module has multiple interfaces and multiple connectors in different directions, and can adapt to different forms of simulation load structures, with strong expandability, maintainability, and versatility. Next, with reference to the accompanying drawings, the specific structures of a simulation load test device for a chassis domain controller and a vehicle provided by the embodiments of the present application are introduced.

[0050] Referring to Figure 1 , in the first aspect, the embodiments of the present application provide a simulation load test device 100 for a chassis domain controller. Among them, the simulation load test device 100 for the chassis domain controller may include a load simulation group 110. It can be understood that the load simulation group 110 can be used to simulate the load connected to the chassis domain controller (not shown in the figure). Compared with the physical load, during the development and debugging stage of the chassis domain controller, the physical load is large in volume, inconvenient to operate, and its safety and versatility need to be improved. The load simulation group 110 in the simulation load test device 100 for the chassis domain controller provided by the embodiments of the present application can simulate the electrical parameters of the load, and the combination and replacement of the load simulation group 110 can be carried out according to needs. It can simulate most loads, has a certain portability, and is convenient for operators to operate.

[0051] Furthermore, referring to Figure 1 , Figure 2 and Figure 4 , the load simulation group 110 may include at least one functional module 120 and a connection component 300. Among them, the functional module 120 may include: a module main body 200 and a path component 400. In a possible implementation manner, the number of the module main body 200, the connection component 300, and the path component 400 may be several, and the embodiments of the present application do not limit this here. It can be understood that the connection component 300 can be used to connect each module main body 200, so that several module main bodies 200 are connected through several connection components 300, and then a simulation load structure is built.

[0052] In the embodiments of the present application, as Figure 2 shown, the module main body 200 may have a receiving cavity 210. Among them, the module main body 200 may have a first interface 250 and a functional interface 260. It can be understood that the first interface 250 may be in the first direction, and the functional interface 260 may be in other directions different from the first direction. In the embodiments of the present application, the connection component 300 may be connected to the functional interface 260.

[0053] Among them, continuing to refer to Figure 1 and Figure 2, the access component 400 can be located in the accommodation cavity 210. Further, as Figure 3 shown, the access component 400 can include a connection path 410 and a functional path 420. It can be understood that both the functional path 420 and the connection path 410 can have a first connector 430 and a functional connector 440. Among them, the first connector 430 can be located at the first interface 250, and the functional connector 440 can be located at the functional interface 260. In a possible implementation manner, the first connector 430 of one of the functional modules 120 can be used to be electrically connected to the chassis domain controller, while the functional connector 440 can be used to simulate one of the loads connected to the chassis domain controller by connecting one or more functional modules 120 through the connection component 300.

[0054] In this way, multiple functional modules 120 are further extended and connected through the connection component 300 to form an analog load structure, which has good scalability and versatility.

[0055] In the embodiments of the present application, it can be understood that, as Figure 3 shown, the connection path 410 and the functional path 420 are not connected to each other, and the connection path 410 and the functional path 420 can be arranged in an interval overlap manner. A plurality of first connectors 430 and functional connectors 440 of the connection path 410 and the functional path 420 can all be connected to the connection component 300, so as to form a plurality of connectable loops to achieve different functions.

[0056] Based on the above embodiments, among them, in a possible implementation manner, the functional module 120 can include one or more of an inductor module, a capacitor module, a resistor module, a wiring module, or the functional module 120 can further include sensors, switches, diodes, etc. The embodiments of the present application do not limit this here.

[0057] Among them, the functional module 120 can further include each electronic module 500. In a possible implementation manner, in combination with Figure 2 and Figure 3 shown, the electronic module 500 can be located in the accommodation cavity 210, and the electronic module 500 can be connected to the functional path 420. Specifically, the electronic module 500 can include an inductor module, a capacitor module, a resistor module, a wiring module, sensors, switches, diodes, etc. In this way, through the setting of one or more modules, the electronic module 500 is formed, and then different types of functional modules 120 are determined.

[0058] It should be noted that the first direction can be the length direction of the module body 200, such as the Figure 2 x direction in Figure 2in the y direction. The third direction may be the height direction of the module body 200, such as Figure 2 in the z direction. The origin where the first direction, the second direction, and the third direction intersect may be set as o. It can be understood that the first direction, the second direction, and the third direction are perpendicular to each other.

[0059] Continuing to refer to Figure 2 , on the basis of the above embodiments, further, the function interface 260 may include a first function interface 261 and a second function interface 262. Among them, the module body 200 may have the first function interface 261 on the surface formed in the xoz direction, and the module body 200 may have the second function interface 262 on the surface formed in the xoy direction.

[0060] Correspondingly, continuing to refer to Figure 2 , the function connector 440 may include a first function connector 441 and a second function connector 442. Among them, the first function connector 441 may be located at the first function interface 261 so that the first function connector 441 corresponds to the first function interface 261. The second function connector 442 may be located at the second function interface 262 so that the second function connector 442 corresponds to the second function interface 262.

[0061] In this way, each interface and each connector are provided on the function module 120 in different directions, and the interfaces and connectors are correspondingly arranged and connected to the connection component 300, so that multiple function modules 120 are further extended and connected through the connection component 300 to form an analog load structure, which has good scalability and versatility.

[0062] On the basis of the above embodiments, it can be understood that the load simulation group 110 may include multiple function modules 120 with different functions. Among them, the structural dimensions of the module bodies 200 of each function module 120 are the same, and the positions of the first interfaces 250 and the function interfaces 260 on the module bodies 200 of each function module 120 correspond one by one. In this way, the size structure design of the function module 120 is standardized and has actual producibility.

[0063] Among them, according to the current production and manufacturing process, the minimum unit volume can be described as a unit volume of 1:1:1. In a possible implementation manner, the actual length corresponding to 1 unit may be about 15 mm, which is not limited in the embodiments of the present application. In this way, a minimum size is set and used as a base number, and the subsequent sizes of the module body 200 can all be multiples of this base number to meet the assembly and use requirements of the low-power electronic load and have actual producibility.

[0064] Continuing to refer to Figure 2, based on the above embodiments, in a possible implementation, the size ratios of the module body 200 in the first direction, the second direction, and the third direction can be 2:1:1. Exemplarily, the sizes of the module body 200 in the first direction, the second direction, and the third direction can be 60 mm, 30 mm, and 30 mm, which are not limited in the embodiments of the present application. It can be understood that the first direction, the second direction, and the third direction are perpendicular to each other, so that the module body 200 has a rectangular structure to achieve a more freely assembled module form with good scalability.

[0065] Continue to refer to Figure 2 , based on the above embodiments, since the module body 200 has a rectangular structure, the module body 200 can have a first surface 220, a second surface 230, and a third surface 240. Among them, in a possible implementation, there can be two of the first surface 220, the second surface 230, and the third surface 240, and the two first surfaces 220 are arranged opposite to each other, the two second surfaces 230 are arranged opposite to each other, and the two third surfaces 240 are arranged opposite to each other.

[0066] Continue to refer to Figure 2 , based on the above embodiments, a first interface 250 can be provided on the first surface 220, and functional interfaces 260 can be provided on the second surface 230 and the third surface 240. Among them, in a possible implementation, the number of the first interface 250 and the functional interfaces 260 can be at least one, which is not limited in the embodiments of the present application. In the embodiments of the present application, exemplarily, one first interface 250 can be provided on the first surface 220, two functional interfaces 260 can be provided on the second surface 230, the two functional interfaces 260 on the second surface 230 can be arranged in parallel, two functional interfaces 260 can also be provided on the third surface 240, the two functional interfaces 260 on the third surface 240 can also be arranged in parallel, and each interface can communicate with the accommodation cavity 210 of the module body 200. It can be understood that the connection component 300 can communicate with the path component 400 through the functional interface 260. In this way, the connection component 300 can be inserted into the functional interface 260 and connected to the path component 400, so as to realize the communication between the connection component 300 and the path component 400.

[0067] It can be understood that by providing two functionally parallel interfaces 260 arranged in parallel on the second surface 230 and the third surface 240, a connection method for realizing the parallel connection of the functional modules 120 can be used.

[0068] It can also be understood that, in a possible implementation manner, each interface opened on the first surface 220, the second surface 230, and the third surface 240 can be located at the center position of each surface, so as to facilitate the connection between each module body 200 and have the ability of splicing and permutation and combination.

[0069] Continuing to refer to Figure 3 , on the basis of the above embodiment, the connection path 410 can have connection branches 411. Among them, in a possible implementation manner, the number of the connection branches 411 can be several, and the embodiments of the present application do not limit this here. In the embodiments of the present application, several connection branches 411 can extend in the first direction, the second direction, and the third direction respectively, and the connection branches 411 can extend to the first connector 430 and the functional connector 440. In this way, it can be ensured that the connection path 410 has connectable connection branches 411 in different directions, so as to facilitate the connection between each module body 200 and have good versatility.

[0070] Continuing to refer to Figure 3 , on the basis of the above embodiment, the functional path 420 can have functional branches 421. Among them, in a possible implementation manner, the number of the functional branches 421 can be several, and the embodiments of the present application do not limit this here. In the embodiments of the present application, several functional branches 421 can extend in the first direction, the second direction, and the third direction respectively, and the functional branches 421 can extend to the first connector 430 and the functional connector 440. In this way, it can be ensured that the functional path 420 has connectable functional branches 421 in different directions, so as to facilitate the connection between each module body 200 and have good versatility. It can be understood that the functional branches 421 and the connection branches 411 in the first direction, the second direction, and the third direction can be arranged in parallel, so as to facilitate the connection component 300 to connect the functional branches 421 and the connection branches 411 to form different circuits.

[0071] On the basis of the above embodiment, the connection branches 411 and the functional branches 421 can take into account the connection modes of parallel and series. Exemplarily, the connection branches 411 and the functional branches 421 can be structures such as wires and circuit boards, and the embodiments of the present application do not limit this here.

[0072] Continuing to refer to Figure 3, on the basis of the above embodiments, the shape of the connection branch 411 may be different from the shape of the functional branch 421. Among them, in a possible implementation manner, one of the connection branch 411 and the functional branch 421 may be a circular structure, and the other of the connection branch 411 and the functional branch 421 may be a rectangular structure. In this way, by setting the shape of the connection branch 411 to be different from the shape of the functional branch 421, the connection branch 411 and the functional branch 421 can have the ability to prevent misconnection, and avoid the situation of incorrect connection when the connection branch 411 and the functional branch 421 are connected to the connection component 300.

[0073] Among them, in a possible implementation manner, the functional branch 421 may be a circular structure, and the connection branch 411 may be a rectangular structure. Or, in another possible implementation manner, the functional branch 421 may be a rectangular structure, and the connection branch 411 may be a circular structure. Of course, in some other embodiments, the functional branch 421 and the connection branch 411 may also be other shapes, and the embodiments of the present application do not limit this here.

[0074] Reference Figure 4 , on the basis of the above embodiments, the connection component 300 may further include: a connection plug 310. Among them, in combination Figure 2 viewed, one end of the connection plug 310 may be inserted into the functional interface 260 and connected to the module main body 200. In a possible implementation manner, the connection plug 310 may include a protruding portion 311 and an extending portion 312. The extending portion 312 may extend along the outer periphery of the protruding portion 311, and the protruding direction of the protruding portion 311 and the extending direction of the extending portion 312 are perpendicular to each other. Among them, the protruding portion 311 may be inserted into the functional interface 260, and the extending portion 312 may abut against the outer edge of the functional interface 260 opened by the module main body 200, so that the connection plug 310 and the module main body 200 are fixedly connected.

[0075] Continuing to refer Figure 4 , on the basis of the above embodiments, in a possible implementation manner, the connection plug 310 may be provided with a first through hole 313 and a second through hole 314. Among them, one of the first through hole 313 and the second through hole 314 may cooperate with the connection branch 411 for the connection branch 411 to pass through, and the other of the first through hole 313 and the second through hole 314 may cooperate with the functional branch 421 for the functional branch 421 to pass through.

[0076] Among them, in a possible implementation manner, the first through hole 313 on the connection plug 310 may be a rectangular through hole for the connection branch 411 to pass through. The second through hole 314 may be a circular through hole for the functional branch 421 to pass through. Alternatively, in another possible implementation manner, the first through hole 313 on the connection plug 310 may be a circular through hole for the functional branch 421 to pass through.
