[0002] As the level of automotive intelligence increases and the functions of electric seats become increasingly complex, traditional electric seat testing devices can no longer meet the testing requirements for vehicles off the production line.
[0003] Currently, the main testing devices for electric seats are used for bench testing at the component stage, but they cannot reflect the actual adjustable range of the electric seat after it is installed in the vehicle, which is affected by the actual installation space, wiring harness layout and component interference. Another method is manual testing after the vehicle rolls off the production line, where workers manually operate the seat adjustment buttons and judge whether the function is normal based on experience and feeling. This method has low testing efficiency, poor consistency and difficulty in quantifying the test results. Summary of the Invention

[0014] In some embodiments, the step of comparing the Hall value travel test data with the expected trend of change to determine whether it conforms to the expected trend of change includes the following steps: Extract a continuous numerical sequence of Hall effect value travel test data within the test period; Analyze the changing trend of the continuous numerical sequence.

This modular design ensures the reliability and data processing efficiency of the testing device.
[0025] This invention also provides a testing method for a vehicle electric seat, see [link to relevant documentation]. Figure 2As shown, the testing method includes the following steps: Step S100: The test task is sent to the acquisition control module 2 via the user interaction terminal 3; Step S200: The acquisition control module 2 obtains the test instruction from the cloud platform 1 and controls the electric seat of the vehicle under test 4 to perform the corresponding action, and collects the test data of the electric seat and sends it to the cloud platform 1; Step S300: The cloud platform 1 analyzes the test data based on the verification rules and outputs the test results. Specifically, the user interaction terminal 3 enables convenient triggering of the test task, the acquisition control module 2 completes the instruction execution and data acquisition, and the cloud platform 1 provides intelligent data verification and result analysis. This achieves full automation from test task issuance to test result output, significantly improving testing efficiency and ensuring the reliability of the testing process.
[0026] As an optional implementation, in one embodiment of the invention, the test instructions include a self-learning test instruction for testing the adjustment range of the electric seat, and a single-function test instruction for verifying the function of a single adjustment direction; the test task must include at least one of the self-learning test instruction and the single-function test instruction. Users can choose to perform a range self-learning test, a targeted single-function test, or a combination of both, according to their actual needs. This expands the adaptability of the testing scenario, satisfying both the complete verification of all seat adjustment functions when a new car rolls off the production line and the precise troubleshooting of specific faults in after-sales maintenance, thereby significantly improving testing efficiency and resource utilization while ensuring testing depth.
[0027] As an optional implementation, in one embodiment of the invention, the self-learning test command includes controlling the electric seat to perform a self-learning action, causing each adjustment motor of the electric seat to move to its corresponding limit position, and recording the Hall value travel test data of each adjustment motor. Specifically, when executing the self-learning test command, the acquisition and control module 2 records the Hall sensor data generated by the corresponding motors during the electric seat's movement to the horizontal forward and backward limit position, the seat cushion height limit position, the backrest angle limit position, and the leg rest extension limit position, forming complete travel test data. This achieves automated and accurate mapping of the actual adjustable space of the electric seat after installation in the vehicle, providing an accurate benchmark range for subsequent functional testing. It effectively solves the problem that traditional testing methods cannot obtain the real travel range under real vehicle conditions, ensuring the reliability of the test.
[0028] As an optional implementation, in one embodiment of the invention, the self-learning action causes at least one or more of the horizontal motor, backrest motor, seat cushion motor, and leg rest motor of the electric seat to move simultaneously or sequentially to their limit positions. This embodiment of the invention enables the acquisition and control module 2 to automatically control the electric seat to move sequentially to its horizontal forward / backward limit position, seat cushion height limit position, backrest angle limit position, and leg rest extension limit position. This achieves automated and accurate mapping of the actual adjustable space of the electric seat after installation, effectively solving the problem that traditional manual inspection cannot accurately obtain the true travel range under actual vehicle installation conditions. It establishes an accurate benchmark range for subsequent functional testing, while automated execution avoids human error and ensures testing efficiency.
[0029] As an optional implementation, in one embodiment of the invention, the single-function test instruction includes controlling the electric seat to perform a single-function test via a test instruction, and collecting Hall value travel test data and current test data of the corresponding motor during the single-function test. In this embodiment of the invention, when performing the single-function test, the acquisition control module 2 synchronously collects the Hall value travel test data and current test data of the corresponding motor to form multi-dimensional functional test data. This enables comprehensive monitoring of the dynamic performance during the adjustment of the electric seat, not only verifying whether the electric seat has completed the specified action, but also accurately diagnosing potential faults such as mechanical jamming and abnormal motor load through motor travel signal trend analysis and motor current signal analysis, thereby improving the depth and accuracy of the functional test.
[0030] As an optional implementation, in one embodiment of the invention, the cloud platform 1 analyzes the test data based on verification rules and outputs test results, including comparing the Hall value travel test data with the standard travel range to determine whether it is within the standard travel range; comparing the Hall value travel test data with the expected change trend to determine whether it conforms to the expected change trend; comparing the current test data with the preset operating current range to determine whether it is within the preset operating current range; if any comparison item does not meet its corresponding verification rule, the test item is determined to be abnormal, and a test result identifying the specific fault is generated. In this embodiment of the invention, by constructing a multi-dimensional, cross-validated automated verification rule set, accurate, efficient, and reliable diagnosis of the functional status of the electric seat is achieved. Specifically, the travel range comparison ensures that the adjusted physical travel conforms to the design specifications, the change trend comparison verifies the consistency between the control logic and mechanical execution, and the current range comparison effectively monitors the load status of the motor, enabling accurate identification and location of different types of potential faults such as motor stall, travel sensor drift, transmission mechanism jamming, or abnormal control unit commands, thereby improving the accuracy and reliability of the detection results.
[0031] As an optional implementation, in one embodiment of the invention, the step of comparing the Hall value travel test data with the expected change trend to determine whether it conforms to the expected change trend includes the following steps: extracting a continuous numerical sequence of the Hall value travel test data within the test time period; analyzing the change trend of the continuous numerical sequence; if the change trend of the continuous numerical sequence is consistent with the expected change trend, it is determined that the corresponding verification rule is met. In this embodiment of the invention, by performing trend analysis on the continuous numerical sequence of the Hall value travel test data, a deep verification of the seat adjustment action process logic is achieved. This method can not only determine whether the final adjustment result is in place, but also effectively capture abnormal states during the adjustment process, such as momentary faults such as mid-process jamming, slow response, or reverse jumping. This overcomes the limitations of relying solely on the start and end point position data for judgment, greatly improving the sensitivity and accuracy of fault detection, and facilitating fault location.
