1. An apparatus for diagnosing a fault of a vehicle component, comprising:
an acceleration sensor for detecting an acceleration signal;
a feature extraction unit for extracting features related to a fault of a vehicle component from the detected acceleration signal; and
a machine learning model for diagnosing a fault of the vehicle component based on the extracted features,
wherein the machine learning model is a model selected according to a preset evaluation index among a plurality of machine learning models trained based on training data sets, and
wherein the preset evaluation index comprises one of accuracy, recall, precision and a combination thereof.
