Abstract: Up to now,the relevant research has some drawbacks:poor robustness,low accuracy rate and non-real time.To solve these problems,a vehicle behavior recognition algorithm of real-time determination and progressive correction on smartphone was proposed.This algorithm classifies vehicle behavior by the data generated during driving process,and uses the collected data as training samples to improve recognition and prediction capability of SVM.For the limitations of traditional sliding window,the endpoint detection algorithm is used to quickly extract useful information from the complete vehicle behavior,which reduces misjudgment simultaneously.The experimental results show that corrective algorithm on time-based segmentation can effectively predict the vehicle behavior,and ultimately achieve high re-cognition rate,which demonstrates the effectiveness of this method.
