Existing EMC testing methods, such as GB34660 and GB / T33012.2-2016 standards, mainly focus on the anti-interference performance under vehicle driving conditions, but lack effective testing schemes for whether intelligent parking systems can operate stably in complex electromagnetic environments. Especially in component-level testing, due to significant differences in layout, cable length, and operating modes compared to the actual vehicle environment, test results cannot fully reflect the EMC performance under real vehicle operating conditions. Furthermore, in vehicle-level testing, since the intelligent parking system is in an inactive state, its functional performance under electromagnetic interference cannot be assessed, resulting in limitations in the testing scheme.

[0037] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0038] With the rapid development of the automotive industry, especially the rise of electric vehicles and autonomous driving technologies, intelligent parking assistance systems have become an important component of vehicle intelligence due to their significant improvement in driving convenience and safety. However, the complexity of intelligent parking assistance systems and their sensitivity to the electromagnetic environment necessitate rigorous electromagnetic compatibility (EMC) testing during the design and verification phases to ensure the stability and reliability of system functions under various electromagnetic interference environments.

[0039] While existing EMC testing standards provide guidance for EMC testing of vehicles under driving conditions, they do not deeply cover the specific testing needs of intelligent parking systems. Specifically, the limitations of existing testing methods for intelligent parking assistance systems are manifested in the following aspects:

[0040] Current EMC testing is typically conducted at two levels. The first is component-level testing, which involves independent evaluation of each component within the intelligent parking system. However, due to significant differences between the testing conditions (layout, cable length, operating status, etc.) and actual vehicle usage, this testing method often fails to fully reflect the EMC performance of components in a real vehicle. In particular, differences in cable length and layout can affect the efficiency and integrity of signal transmission, thus impacting the accuracy of test results.

[0041] While vehicle-level EMC testing can assess a vehicle's overall anti-interference capabilities in an environment closer to real-world driving conditions, the intelligent parking system is typically inactive during the test. This means the test cannot reflect the system's true performance under electromagnetic interference, nor can it identify whether the system can maintain stable operation under such conditions. This limitation may lead to insufficient testing of key functions, failing to comprehensively evaluate the EMC performance of the intelligent parking assistance system, especially its adaptability and robustness in complex electromagnetic environments.

[0042] This application provides an intelligent parking electromagnetic interference testing auxiliary device, such as... Figure 1As shown, the system includes: a shielding box 7 with a mounting cavity; a support module 2 disposed within the mounting cavity and connected to the shielding box 7, the support module 2 having an initial position for the vehicle under test to contact the ground, and a test position for raising the vehicle under test to a preset height; and a wheel detection assembly disposed within the mounting cavity and connected to the shielding box 7, the wheel detection assembly being spaced apart from the support module 2. When the vehicle under test is in the test position, the wheel detection assembly is used to acquire parking data of at least one wheel of the vehicle under test, wherein the parking data includes at least: steering angle data, wheel position data, and wheel attitude data.

[0043] The technical solution of this utility model provides a closed and shielded environment for testing by including a shielded box 7 with an installation cavity, a support module 2, and a wheel detection component. This ensures that the test is not affected by external electromagnetic interference. The support module 2 can accurately lift the vehicle under test to a preset height to simulate actual parking conditions, while ensuring the stability and safety of the vehicle. This solves the problem that current testing methods in the prior art cannot accurately evaluate the anti-interference capability of the vehicle's intelligent parking system in the actual electromagnetic environment in component-level verification and vehicle-level radiation immunity testing.

[0044] Furthermore, in order to satisfy the requirement that the support module 2 has an initial position for the vehicle under test to contact the ground, and that the support module 2 has a test position for raising the vehicle under test to a preset height, the support module 2 can use a hydraulic lifting platform or an electric lifting platform to realize the corresponding height adjustment function, and can change the position of the support point through a preset program or manual adjustment to meet the specific needs of the test vehicle.

[0045] Furthermore, the intelligent parking electromagnetic interference testing auxiliary device also includes: a limit module 4, which is installed in the mounting cavity and connected to the shielding box 7.

The execution end of one of the two limit modules 4 is connected to the first end of the vehicle under test, and the execution end of the other limit module 4 is connected to the second end of the vehicle under test.

[0046] The above-described optional embodiments achieve the following beneficial effects: The limiting module 4 effectively restricts the unexpected movement of the vehicle during testing, especially when the vehicle is subjected to electromagnetic interference. It can respond immediately to prevent the vehicle from shifting or colliding due to system malfunction, greatly reducing testing risks. Simultaneously, the synergistic effect of the limiting module 4, support module 2, and wheel detection components ensures accurate collection of wheel detection data when the vehicle is in the preset test position, thereby providing a more comprehensive and accurate assessment of the functional safety and performance reliability of the intelligent parking system under electromagnetic interference conditions.

The wheel detection module 1 is used to acquire parking data of at least one wheel of the vehicle under test, wherein the parking data includes at least: steering angle data, wheel position data, and wheel attitude data; wherein, when the vehicle under test is located at the test position, the execution end has a working position for contacting the wheel detection module 1 with the wheel, and a separation position for separating the wheel detection module 1 from the wheel.

[0048] The above optional embodiments can achieve the following beneficial effects: the wheelbase adjustment module 3 can be flexibly adjusted to match the specific wheelbase of the vehicle under test, ensuring the wide applicability and accuracy of the test. The wheel detection module 1 and the wheelbase adjustment module 3 work closely together, which can accurately contact the wheels in the working position to obtain real-time parking dynamic data, and avoid interfering with the normal movement of the vehicle in the separated position, ensuring the safety and efficiency of the test process.

[0049] Furthermore, in order to meet the requirements of the wheelbase adjustment module 3, a robotic arm can be used to match the wheelbase of different vehicle models, adapt to a wider range of testing needs, and ensure the accuracy and reliability of the test results.
