[0002] In recent years, my country's automotive industry has developed rapidly, and it will remain a core area of ​​development in the future. To meet the actual testing and application requirements of automobiles, it is necessary to quickly build chassis domain test benches to complete external load testing of controllers and evaluate their performance. This includes testing for inductive loads, capacitive loads, linear impedance loads, and other combined loads.

[0003] Typically, a common testing method involves using physical loads to simulate real-world operating conditions. However, physical loads are often bulky, difficult to move and place, and lack portability, especially when testing and verifying in different locations, increasing testing, transportation, and space costs. Currently, chassis domain controller testing and verification using real loads suffers from problems such as large size, difficulty in transporting, high transportation costs, and high replacement costs.

[0004] In addition, simulated loads can be used for testing. This method can also simulate actual working conditions to a great extent and has a small size, making it somewhat portable.

[0043] As described in the background section, a common testing method involves using physical loads. This method can simulate actual working conditions. However, in most cases, physical loads are bulky, difficult to move and place, and lack portability. This is especially true when testing and verifying in different locations, increasing testing time, transportation, and space costs. Currently, chassis domain controller testing and verification using real loads suffers from problems such as large size, difficulty in transporting, high transportation costs, and high replacement costs.

[0044] In addition, simulated loads can be used for testing. This method can also simulate actual working conditions to a great extent and has a small size, making it somewhat portable. However, this device is generally a custom-made product with poor versatility and expandability.

[0045] To address the aforementioned technical problems, embodiments of this application provide a simulated load testing device for a chassis domain controller and a vehicle. The simulated load testing device for a chassis domain controller provided in the first aspect of this application includes a load simulation group for simulating 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 having a receiving cavity, a first interface in a first direction and a functional interface in a direction different from the first direction, and a connection component connected to the functional interface; a pathway component located in the receiving cavity, including a connection pathway and a functional pathway, both the functional pathway and the connection pathway having a first connector at the first interface and a functional connector at the functional interface, wherein the first connector of one functional module is used for electrical connection to the chassis domain controller, and the functional connector is used to simulate one or more functional modules as one of the loads connected to the chassis domain controller through the connection component; and an electronic module located in the receiving cavity and connected to the functional pathway. Thus, the chassis domain controller simulation load testing device provided in this application embodiment, by connecting to the chassis domain controller, realizes the performance testing of the chassis domain controller. It is small in size, easy to carry, and can simulate actual working conditions to a certain extent. By setting at least one functional module, connection component, and path component, a simulation load structure is constructed. The functional module has multiple interfaces and multiple connectors in different directions, which can adapt to different types of simulation load structures. The modules can be combined and replaced as needed, and have strong scalability, maintainability, and versatility.

[0046] A second aspect of this application provides a vehicle including a chassis domain controller. The chassis domain controller is connected to a simulated load testing device for the aforementioned chassis domain controller to perform load testing.

[0047] The embodiments of this application will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be understood that the preferred embodiments are only for illustrating this application and are not intended to limit the scope of protection of this application.

[0048] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0049] This application provides a simulated load testing device for a chassis domain controller and a vehicle. By setting at least one functional module, connection components, and pathway components, a simulated load structure is constructed. The functional module has multiple interfaces and connectors in different directions, enabling it to adapt to different forms of simulated load structures and exhibiting strong scalability, maintainability, and versatility. The specific structure of the simulated load testing device for a chassis domain controller and the vehicle provided in this application will be described below with reference to the accompanying drawings.

[0050] refer to Figure 1 This application provides a simulated load testing device 100 for a chassis domain controller in a first aspect. The simulated load testing device 100 may include a load simulation group 110. It is understood that the load simulation group 110 can be used to simulate loads connected to the chassis domain controller (not shown in the figure). Compared to physical loads, physical loads are bulky, inconvenient to operate, and have limitations in safety and versatility during the development and debugging phase of the chassis domain controller. The load simulation group 110 in the simulated load testing device 100 provided in this application can simulate load electrical parameters, and the load simulation group 110 can be combined and replaced as needed. It can simulate most loads, has a certain degree of portability, and is easy for operators to use.

[0051] Further, refer to Figure 1 , Figure 2 as well as Figure 4 The load simulation group 110 may include at least one functional module 120 and a connection component 300. The functional module 120 may include a module body 200 and a path component 400. In one possible implementation, the number of module bodies 200, connection components 300, and path components 400 may be multiple, and this embodiment of the application is not limited thereto. It is understood that the connection component 300 can be used to connect the various module bodies 200, thereby connecting several module bodies 200 through several connection components 300 to form a simulated load structure.

[0052] In the embodiments of this application, such as Figure 2 As shown, the module body 200 may have a receiving cavity 210. The module body 200 may have a first interface 250 and a functional interface 260. It is understood that the first interface 250 may be located in a first direction, and the functional interface 260 may be located in a direction different from the first direction. In this embodiment, the connecting component 300 may be connected to the functional interface 260.

[0053] Among them, continue to refer to Figure 1 as well as Figure 2The passage component 400 can be located within the receiving cavity 210. Further, as... Figure 3 As shown, the pathway component 400 may include a connection pathway 410 and a functional pathway 420. It is understood that both the functional pathway 420 and the connection pathway 410 may have a first connector 430 and a functional connector 440. The first connector 430 may be located at the first interface 250, and the functional connector 440 may be located at the functional interface 260. In one possible implementation, the first connector 430 of one of the functional modules 120 can be used for electrical connection to a chassis domain controller, while the functional connector 440 can be used to simulate one or more functional modules 120 as one of the loads connected to the chassis domain controller via the connection component 300.

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

[0055] In the embodiments of this application, it can be understood that, as Figure 3 As 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 interleaved at intervals. Several first connectors 430 and functional connectors 440 of the connection path 410 and the functional path 420 can be connected to the connection component 300 to form several interconnected loops to achieve different functions.

[0056] Based on the above embodiments, in one possible implementation, the functional module 120 may include one or more of an inductor module, a capacitor module, a resistor module, and a wiring module. Alternatively, the functional module 120 may also include a sensor, a switch, a diode, etc. The embodiments of this application are not limited herein.

[0057] The functional module 120 may further include various electronic modules 500. In one possible implementation, combined with Figure 2 as well as Figure 3 As shown, the electronic module 500 can be located in the receiving cavity 210, and the electronic module 500 can be connected to the functional path 420. Specifically, the electronic module 500 may include an inductor module, a capacitor module, a resistor module, a wiring module, a sensor, a switch, a diode, etc. In this way, by setting one or more modules, the electronic module 500 is formed, thereby determining different types of functional modules 120.

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

[0059] Continue to refer to Figure 2 Based on the above embodiments, the functional interface 260 may further include a first functional interface 261 and a second functional interface 262. Specifically, the module body 200 may have the first functional interface 261 on the surface formed in the xoz direction, and the module body 200 may have the second functional interface 262 on the surface formed in the xoy direction.

[0060] Accordingly, continue to refer to Figure 2 The functional connector 440 may include a first functional connector 441 and a second functional connector 442. The first functional connector 441 may be located at the first functional interface 261, so that the first functional connector 441 corresponds to the first functional interface 261. The second functional connector 442 may be located at the second functional interface 262, so that the second functional connector 442 corresponds to the second functional interface 262.

[0061] In this way, each functional module 120 is provided with an interface and a connector in different directions, and the interfaces and connectors are set accordingly and connected to the connecting component 300. This allows multiple functional modules 120 to be further extended and connected through the connecting component 300 to form a simulated load structure, which has good scalability and versatility.

[0062] Based on the above embodiments, it can be understood that the load simulation group 110 may include multiple functional modules 120 with different functions. The main body 200 of each functional module 120 has the same structural dimensions, and the positions of the first interface 250 and the functional interface 260 on the main body 200 of each functional module 120 correspond one-to-one. This ensures that the size and structural design of the functional modules 120 are standardized and practically manufacturable.

[0063] According to current manufacturing processes, the minimum unit volume can be described as a 1:1:1 unit volume. In one possible implementation, the actual length corresponding to 1 unit can be approximately 15mm, and this embodiment of the application does not impose any limitations on this. Thus, by setting a minimum size and using this size as a base, the dimensions of subsequent module bodies 200 can all be multiples of this base, thereby meeting the assembly and use requirements of low-power electronic loads and ensuring practical manufacturability.

[0064] Continue to refer to Figure 2Based on the above embodiments, in one possible implementation, the dimensional ratio of the module body 200 in the first direction, the second direction, and the third direction can be 2:1:1. For example, the dimensions of the module body 200 in the first direction, the second direction, and the third direction can be 60mm, 30mm, and 30mm, respectively; this embodiment is not limited thereto. It is understood that the first direction, the second direction, and the third direction are perpendicular, thereby making the module body 200 have a rectangular structure, achieving a more flexible modular 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 may have a first surface 220, a second surface 230, and a third surface 240. In one possible implementation, there may be two first surfaces 220, two second surfaces 230, and two third surfaces 240, with the two first surfaces 220, the two second surfaces 230, and the two third surfaces 240 arranged opposite each other.

[0066] Continue to refer to Figure 2 Based on the above embodiments, a first interface 250 may be provided on the first surface 220, and functional interfaces 260 may be provided on the second surface 230 and the third surface 240. In one possible implementation, the number of the first interface 250 and the functional interfaces 260 may be at least one, and this application embodiment does not impose a limitation. In this application embodiment, exemplarily, the first surface 220 may have one first interface 250, the second surface 230 may have two functional interfaces 260, which may be arranged side-by-side, and the third surface 240 may also have two functional interfaces 260, which may also be arranged side-by-side, and each interface may be connected to the receiving cavity 210 of the module body 200. It is understood that the connecting component 300 can be connected to the passage component 400 through the functional interface 260. Thus, the connecting component 300 can be inserted into the functional interface 260 and connected to the passage component 400, thereby realizing the connection between the connecting component 300 and the passage component 400.

[0067] It is understandable that by setting two parallel functional interfaces 260 on the second surface 230 and the third surface 240, the functional modules 120 can be connected in parallel.

[0068] It is also understood that, in one possible implementation, the interfaces opened on the first surface 220, the second surface 230 and the third surface 240 can be located at the center of each surface, thereby facilitating the connection between the various module bodies 200 and enabling them to be assembled and combined.

[0069] Continue to refer to Figure 3 Based on the above embodiments, the connection path 410 may have connection branches 411. In one possible implementation, the number of connection branches 411 can be several, and this application embodiment does not limit this. In this application embodiment, several connection branches 411 can extend upwards in the first direction, the second direction, and a third direction, respectively, and the connection branches 411 can extend to the first connector 430 and the functional connector 440. This allows the connection path 410 to have connectable connection branches 411 in different directions, thereby facilitating the connection between the various module bodies 200 and providing good versatility.

[0070] Continue to refer to Figure 3 Based on the above embodiments, the functional path 420 may have functional branches 421. In one possible implementation, the number of functional branches 421 can be several, and this application embodiment does not limit this. In this application embodiment, several functional branches 421 can extend upwards in the first direction, the second direction, and a third direction, respectively, and the functional branches 421 can extend to the first connector 430 and the functional connector 440. This allows the functional path 420 to have connectable functional branches 421 in different directions, facilitating the connection between the various module bodies 200 and providing good versatility. It is understood that the functional branches 421 and connecting branches 411 in the first direction, the second direction, and the third direction can be arranged in parallel, facilitating the connection component 300 to connect the functional branches 421 and the connecting branches 411 to form different loops.

[0071] Based on the above embodiments, the connecting branch 411 and the functional branch 421 can accommodate both parallel and series connection methods. Exemplarily, the connecting branch 411 and the functional branch 421 can be structures such as wires or circuit boards; this embodiment of the application is not limited thereto.

[0072] Continue to refer to Figure 3Based on the above embodiments, the shape of the connecting branch 411 may differ from the shape of the functional branch 421. In one possible implementation, one of the connecting branch 411 and the functional branch 421 may be a circular structure, while the other may be a rectangular structure. Thus, by allowing the shape of the connecting branch 411 to differ from that of the functional branch 421, the connecting branch 411 and the functional branch 421 can be designed to prevent incorrect connection when connected to the connecting assembly 300.

[0073] In one possible implementation, the functional branch 421 can be a circular structure, while the connecting branch 411 can be a rectangular structure. Alternatively, in another possible implementation, the functional branch 421 can be a rectangular structure, while the connecting branch 411 can be a circular structure. Of course, in other embodiments, the functional branch 421 and the connecting branch 411 can also be other shapes, and this application embodiment is not limited thereto.

[0074] refer to Figure 4 Based on the above embodiments, the connection component 300 may further include: a connection plug 310. Wherein, combined with Figure 2 As can be seen, one end of the connector 310 can be inserted into the functional interface 260 and connected to the module body 200. In one possible embodiment, the connector 310 may include a protrusion 311 and an extension 312. The extension 312 can extend along the outer periphery of the protrusion 311, and the protruding direction of the protrusion 311 is perpendicular to the extending direction of the extension 312. The protrusion 311 can be inserted into the functional interface 260, while the extension 312 can abut against the outer edge of the functional interface 260 on the module body 200, thereby fixing the connector 310 and the module body 200 together.

[0075] Continue to refer to Figure 4 Based on the above embodiments, in one possible implementation, the connector 310 may have a first through hole 313 and a second through hole 314. One of the first through hole 313 and the second through hole 314 may mate with the connecting branch 411 for passage, while the other of the first through hole 313 and the second through hole 314 may mate with the functional branch 421 for passage.

[0076] In one possible implementation, the first through hole 313 on the connector 310 can be a rectangular through hole for the connection branch 411 to pass through. The second through hole 314 can be a circular through hole for the functional branch 421 to pass through. Alternatively, in another possible implementation, the first through hole 313 on the connector 310 can be a circular through hole for the functional branch 421 to pass through, while the second through hole 314 can be a rectangular through hole for the connection branch 411 to pass through. Of course, in other embodiments, the first through hole 313 and the second through hole 314 can also have other shapes, and this application does not limit the specific embodiments described herein.

[0077] Based on the above embodiments, by way of example, the connector 310 may include a line connector, a line shorter, a module connector, and a module protector, and different connectors 310 can be connected according to different functional requirements. Figure 4 The connector 310 shown in the diagram consists of, from left to right, a line connector, a line jumper, a module connector, and a module protector.

[0078] Continue to refer to Figure 4 Based on the above embodiments, in one possible implementation, when the connector 310 uses a line connector, both ends of the extension 312 of the connector 310 can have protrusions 311. Each protrusion 311 has a first through hole 313 and a second through hole 314, and the first through holes 313 on the two protrusions 311 are connected, and the second through holes 314 on the two protrusions 311 are connected, facilitating the passage of the connecting branch 411 and the functional branch 421. Thus, combined with... Figure 1 As can be seen, the two protrusions 311 can be inserted into the functional interfaces 260 of the two module bodies 200 respectively, thereby enabling multiple module bodies 200 to be connected through the connector plug 310. The connection branch 411 and functional branch 421 in one module body 200 can pass through the first through hole 313 and the second through hole 314 of the connector plug 310 to another module body 200 and connect with the passage component 400 in the other module body 200.

[0079] Continue to refer to Figure 4Based on the above embodiments, in one possible implementation, when the connector 310 uses a line shorter, one end of the extension 312 of the connector 310 has a protrusion 311, and the protrusion 311 has a first through hole 313 and a second through hole 314. Thus, the connecting branch 411 can be inserted into one of the first through hole 313 and the second through hole 314, and the functional branch 421 can be inserted into the other of the first through hole 313 and the second through hole 314, thereby connecting the connecting branch 411 and the functional branch 421 to form a circuit.

[0080] Continue to refer to Figure 4 Based on the above embodiments, in one possible implementation, when the connector 310 is a modular connector, both ends of the extension 312 of the connector 310 can have protrusions 311. Thus, when the two module bodies 200 do not require electrical connection, the two protrusions 311 of the connector 310 can be respectively inserted into the functional interfaces 260 of the two module bodies 200, thereby enabling multiple module bodies 200 to be connected via the connector 310.

[0081] Continue to refer to Figure 4 Based on the above embodiments, in one possible implementation, when the connector 310 uses a module protector, one end of the extension 312 of the connector 310 has a protrusion 311. In this way, the protrusion 311 of the connector 310 can be inserted into the functional interface 260 of the module body 200, whereby the connector 310 is used to cover the functional interface 260, thereby preventing short circuits.

[0082] refer to Figure 5 as well as Figure 6 Based on the above embodiments, the simulated load testing device for the chassis domain controller may further include a wiring module 320. In one possible implementation, the wiring module 320 may have a first end 321 and a second end 322. The first end 321 may be inserted into the first interface 250 and connected to the functional module 120. The second end 322 may be used to connect to the chassis domain controller (not shown in the figure), thereby enabling the chassis domain controller and the module body 200 to communicate via the wiring module 320.

[0083] Continue to refer to Figure 5Based on the above embodiments, in one possible implementation, the first end 321 of the wiring module 320 may be provided with a first via 3211 and a second via 3212.

[0084] In one possible implementation, the first via 3211 on the first end 321 of the wiring module 320 can be a rectangular through hole for the connection branch 411 to pass through. The second via 3212 can be a circular through hole for the functional branch 421 to pass through. Alternatively, in another possible implementation, the first via 3211 on the first end 321 of the wiring module 320 can be a circular through hole for the functional branch 421 to pass through, while the second via 3212 can be a rectangular through hole for the connection branch 411 to pass through. Of course, in other embodiments, the first via 3211 and the second via 3212 can also have other shapes, and this application does not limit the specific shapes.

[0085] Continue to refer to Figure 6 Based on the above embodiments, the second end 322 of the wiring module 320 may have a first port 3221 and a second port 3222. In one possible implementation, the connection branch 411 and the functional branch 421 may respectively pass through the first port 3221 and the second port 3222, and connect to the chassis domain controller. In this way, the wiring module 320 can provide connection branches 411 and functional branches 421 to the module body 200 and the chassis domain controller, making the connection between the load simulation group 110 and the chassis domain controller more reliable.

[0086] Based on the above embodiments, in one possible implementation, the first port 3221 and the second port 3222 opened on the second end 322 of the wiring module 320 can be quick-released by pressing, which is convenient for installation and disassembly, thereby facilitating the lead-out of the connection branch 411 and the functional branch 421, and further facilitating the connection between the module body 200 and the chassis domain controller.

[0087] Continue to refer to Figure 6Based on the above embodiments, in one possible implementation, the dimensional ratio of the wiring module 320 in the first direction, the second direction, and the third direction can be 1:2:2. For example, the dimensions of the wiring module 320 in the first direction, the second direction, and the third direction can be 15mm, 30mm, and 30mm, respectively; this embodiment is not limited thereto. It is understood that the wiring module 320 can have a rectangular structure, and the dimensions of the wiring module 320 can match the module body 200 to achieve a more flexible modular form with good scalability.

[0089] Continue to refer to Figure 2 Based on the above embodiments, in one possible implementation, the adjusting member 600 can be an adjusting knob. Thus, by rotating the adjusting knob, the capacitance, resistance, inductance, and other parameter values ​​of the module body 200 can be adjusted according to the different types of functional modules 120.

[0090] Continue to refer to Figure 2 Based on the above embodiments, the chassis domain controller's simulated load testing device 100 may further include a nameplate 700. The nameplate 700 may be disposed on the module body 200. It is understood that the nameplate 700 can be used to indicate the functional type of the functional module 120. Alternatively, the nameplate 700 may also be used to indicate the physical characteristic parameters, adjustment range, etc., of the functional module 120; however, this embodiment does not impose any limitations.

[0091] It should be noted that, for example, L can represent inductance, C can represent capacitance, and R can represent resistance.

[0092] In one possible implementation, the module body 200 may be provided with heat dissipation holes (not shown in the figure) depending on the actual power consumption.

The chassis domain controller can be connected to the analog load testing device 100 of the aforementioned chassis domain controller to perform load testing.

[0094] In one possible implementation, exemplarily taking seat heating as an example, when testing the chassis domain controller's control over the seat heating function, the simulated load testing device 100 for the chassis domain controller provided in this application embodiment can effectively simulate the electrical characteristics of the actual seat heating element. Specifically, the electronic module 500 in the functional module 120 can be replaced with a resistor module to form a resistor module, which is then connected to the chassis domain controller via the path component 400 and the wiring module 320. Thus, the seat heating function is activated through the chassis domain controller. The response of the resistor module is observed to ensure that the simulated parameters are consistent with the actual parameters. The values ​​of each parameter on the functional module 120 are recorded. These parameter values ​​are ensured to be within the rated range of the seat heating element to test the reliability of the chassis domain controller.

[0095] In another possible implementation, exemplarily taking a large engine as an example, when testing the chassis domain controller's control over engine functions, the simulated load testing device 100 for the chassis domain controller provided in this application embodiment can effectively simulate the electrical characteristics of an actual engine. Wherein, as Figure 1 As shown, the electronic module 500 in functional module 120 can be composed of two capacitor modules, one inductor module, and one resistor module, forming two capacitor modules, one inductor module, and one resistor module. These modules are then connected to the chassis domain controller via the path assembly 400 and the wiring module 320. This allows the engine to be started via the chassis domain controller. The responses of each module are observed to ensure that the simulated parameters match the actual parameters. The parameter values ​​on functional module 120 are recorded. These parameter values ​​are ensured to be within the engine's rated range to test the reliability of the chassis domain controller.

[0096] Of course, in other embodiments, different types of functional modules 120 can be used to build different simulated load structures according to different needs, and the performance of the chassis domain controller can be tested. This application embodiment is not limited here.

[0097] In this embodiment of the application, the chassis domain controller simulation load testing device 100 provided in this embodiment of the application is configured with at least one functional module 120, a connection component 300 and a path component 400 to form a simulation load structure.
