Therefore, it is necessary to carry out teaching, training, development and testing research on vehicle power systems. However, existing teaching, training and development testing equipment has problems such as limited functions, poor simulation effects, inability to simulate dynamic working conditions, and inability to conduct multi-device collaborative debugging.

[0031] Specifically, the equipment includes: a powertrain assembly bench 1 and a bench base 2; the powertrain assembly bench 1 includes a vehicle component, which includes front and rear wheels; wherein, the front wheel is placed on the surface of the corner plate 3 of the bench base 2; the rear wheel is placed on the surface of the roller assembly 4 of the bench base 2; a lifting eye bolt group 5 is respectively provided on the first side of the corner plate 3 and the second side of the roller assembly 4 of the bench base 2; the powertrain assembly bench 1 and the bench base 2 are elastically connected by elastic connectors through the lifting eye bolt group 5.

[0033] The above content will be described more comprehensively below with reference to specific embodiments and accompanying drawings.

[0035] like Figures 1-2 As shown, the equipment includes a powertrain assembly bench 1 and a bench base 2. The powertrain assembly bench 1 is equipped with a real vehicle component.

[0044] Instrument display modules may include: instrument display screens, indicator light display screens, etc.

[0046] The lighting module may include: headlights, taillights, low and high beams, turn signals, etc.
[0047] Since the components in the actual vehicle, except for the fault setting controller group, are all commonly used vehicle components, and the settings of the components are also common settings in actual vehicles, this disclosure will not elaborate further.
[0048] Furthermore, at least one side of the test bench base 2 is provided with a light strip, and at least one side is provided with an independent power interface to power the light strip; the rear wheels of the power system assembly test bench 1 can also be provided with protective covers for dust and dirt prevention.
[0049] Figures 3-4 The diagram illustrates an application example of a power system development and testing device provided in an embodiment of this disclosure.
[0050] like Figures 3-4 As shown, the powertrain assembly bench 1 is equipped with actual vehicle components. Among the front and rear wheels of the actual vehicle components, the front wheels are placed on the surface of the corner plate 3 of the bench base 2; the rear wheels are placed on the surface of the roller assembly 4 of the bench base 2. The roller assembly 4 consists of a pair of double rollers, and the rear wheels are respectively clamped onto the surfaces of the two pairs of roller assemblies 4. The first side of the corner plate 3 of the bench base 2 and the second side of the roller assembly 4 are respectively provided with eye bolt groups 5. The powertrain assembly bench 1 and the bench base 2 are elastically connected by elastic connectors through the eye bolt groups 5. The side surfaces of the bench base 2 are all provided with light strips, and the rear side surface is provided with a power interface to supply power to the light strips.
[0051] like Figures 3-4 As shown, the actual vehicle components include: a frame 6, front and rear suspensions and suspension beam assemblies 7. The frame 6 carries the power module, control module, steering assembly, sensing module, instrument display module, electrical module, lighting module, etc. The front and rear suspensions and suspension beam assemblies 7 are located at the front and rear ends of the frame 6, respectively, and are mechanically connected to the frame 6. Furthermore, the frame 6 is provided with a central control beam 8, which is provided with a joint debugging interface 9 and wiring holes. The equipment can be jointly debugged with the battery management system development and testing equipment and the power system development and testing bench through the joint debugging interface 9.
[0052] Figures 5-6 An example diagram of the debugging equipment provided in an embodiment of this disclosure is shown.
[0053] like Figure 5 As shown, the integration testing equipment is a power system development and testing bench. The bench supports a teaching board with test ports. The side of the cover plate supporting the teaching board has an integration interface, which can be electrically connected to the power system development and testing equipment provided in this disclosure to carry out integration testing.
[0054] like Figure 6As shown, the debugging equipment is a battery management system development and testing equipment.

[0055] In this embodiment, the devices are connected via their interface to enable collaborative operation, allowing for synchronous communication. Furthermore, the battery management system development and testing equipment powers the powertrain assembly bench of the powertrain development and testing equipment. Operators perform operations on the powertrain assembly bench, and the powertrain development and testing equipment feeds data back to the battery management system development and testing equipment. The battery management system development and testing equipment receives the data and displays relevant parameters or simulated scenarios in real time on its display component. Simultaneously, relevant test parameters can be obtained and verified through the powertrain development and testing bench. During fault setting experiments, faults are set using the accompanying software integrated into the display component of the battery management system development and testing equipment. This causes the fault setting controller group of the powertrain development and testing equipment to begin corresponding fault control operations. At this time, the powertrain development and testing equipment can actually react to the corresponding fault, and the powertrain development and testing bench can detect the corresponding fault parameters. After the operator overcomes the fault on the powertrain development and testing equipment, the fault simulation ends, and the feedback can be viewed on the battery management system development and testing equipment, while the relevant parameters can be detected on the powertrain development and testing bench.
[0056] It is understandable that each device can operate independently even without being connected to the joint commissioning line, and the power supply can be an AC-DC bidirectional power supply.
[0057] According to the embodiments of this disclosure, the following technical effects are achieved:
[0058] The equipment integrates various real vehicle components and, together with the fault setting controller group, can simulate various fault scenarios. It is not only suitable for powertrain performance development testing, but also for teaching and training, fault diagnosis research and other functions, providing a more realistic experimental environment for powertrain testing. It supports joint debugging and verification, which can improve testing efficiency and system compatibility, adapt to the powertrain systems of various different vehicle models, and has good scalability and versatility.
[0059] It should be noted that the specific embodiments described above do not constitute a limitation on the scope of protection of this disclosure. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors.
