The present invention relates to an electric power steering rattle inspection system capable of abstracting multidimensional data through a nonlinear conversion technique based on a neural network, and inspecting the rattle of electric power steering through a method of extracting core information determining performance. The electric power steering rattle inspection system includes: a rattle inspection control device controlling the entire operation of a rattle inspection on electric power steering (EPS), and providing a load state in a condition proper for a driving road; an inspection equipment driving part applying a load proper for the driving road to inspection equipment in accordance with the control of the rattle inspection control device; EPS rattle inspection equipment applying vibrations to the EPS in accordance with the operation of the inspection equipment driving part; and an analysis evaluation part evaluating the rattle of the EPS by converting a vibration signal generated from the EPS rattle inspection equipment into image data and then analyzing the data through a deep learning-based malfunction prediction analysis algorithm. Therefore, an electric power steering rattle inspection system based on deep learning malfunction prediction analysis can be created.

    신경망 기반의 비선형 변환기법을 활용하여 다차원의 데이터를 추상화하고, 성능을 결정하는 핵심적인 정보를 추출하는 방법으로 전동식 조향장치의 래틀을 검사할 수 있는 딥러닝 고장예측 분석기반 전동식 조향장치 래틀 검사시스템에 관한 것으로서, 전동식 조향장치(EPS)의 래틀 검사의 전체 동작을 제어하며, 주행도로에 맞는 조건의 부하상태를 제공하는 래틀 시험 제어장치, 래틀 시험 제어장치의 제어에 따라 검사장비에 주행도로에 맞는 부하를 인가하는 검사장비 구동부, 검사장비 구동부의 구동에 따라 전동식 조향장치에 진동을 가하는 EPS 래틀 검사장비 및 EPS 래틀 검사장비로부터 발생하는 진동신호를 이미지 데이터로 변환한 후 딥러닝 기반 고장예측 분석 알고리즘으로 분석하여 전동식 조향장치의 래틀을 평가하는 분석 평가부를 포함하여, 딥러닝 고장예측 분석기반 전동식 조향장치의 래틀 검사시스템을 구현한다.
