In this paper, we propose a new method for driving style recognition on the basis of SAX and bitmap technology. This method converts the sensor signal into a discrete symbol sequence and uses a bitmap for feature extraction. The weight matrix is generated based on the vector space model (VSM) to characterize the driving style fingerprint. Different from the traditional driving feature representation method, we propose a new concept of using bitmap to represent driving fingerprints. Given the sensor data captured by the vehicle during natural driving, we regard driving style recognition as a time series classification task and divides it into three classifications: normal driving, aggressive driving and drowsy driving. We evaluate our proposed model on the open natural driving behavior classification dataset UAH-DriveSet. Compared with traditional classification methods, our proposed model achieves the most advanced results on UAH-DriveSet, achieving 83% and 95% F1-measure scores in motorway and secondary road, which is more than 20% higher than the closest comparison method.
