The detection of noise and current in the diagnosis of faults in automotive power seats cannot be performed simultaneously, and existing detection technologies cannot detect newly added functions of the seats. This paper designs and develops an automotive power seat fault detection system based on LabVIEW, which consists of hardware and software parts. It can synchronously collect noise and current signals generated during seat operation. The LabVIEW detection program processes the collected data in real-time, including waveform and numerical display, data analysis and evaluation, data storage, and retrieval functions. Finally, the system is tested and validated in actual production, demonstrating its efficient and accurate detection of faulty seats and its practical application value.
