Vibration signal analysis of vehicle in highway based on AR model

The AR model method was applied in this paper to analyze the information extraction of vehicle vibration signals in highway traffic flow. Based on the sample data and appropriate AR model method, the feature vectors were used to distinguish different vehicle models. The proposed feature method in vehicle signal recognition technology can achieve the requirement of auxiliary determination. It demonstrated that the feasibility of model identification and feature extraction using the highway vehicle vibration signal. The result showed that the AR model is an effective method in vehicle type classification.
