Abstract

The invention discloses a systematic clustering thought-based driving behavior identification method. The driving behavior identification method comprises the following steps of building a statisticalfeature model; performing driving behavior data collection by utilizing an inertial sensor; filtering data by utilizing a Kalman filter; extracting effective driving behavior data from the filtered data by adopting an adaptive window function method, and further extracting statistical features of the effective data; performing screening to obtain optimal statistical features; and classifying thestatistical features of the driving behavior data, and identifying corresponding driving behaviors. The invention provides the systematic driving behavior identification method with extremely few features, extremely low calculation amount and extremely high precision based on a clustering thought; and the method has wide application prospects in the fields of social safety, car insurances, fleet management and the like.

Description

technical field [0001] Based on the idea of ​​clustering, the present invention proposes a systematic driving behavior recognition method, which belongs to the fields of signal processing, pattern recognition and machine learning. Background technique [0002] According to data from the Traffic Management Bureau of the Ministry of Public Security, as of the end of June 2017, the number of motor vehicles in the country reached 304 million, including 205 million cars. While the popularity of automobiles brings convenience to people's lives, it also brings potential safety hazards that cannot be ignored. According to data from the National Bureau of Statistics, there were 187,781 traffic accidents across the country in 2015, including 170,130 motor vehicle traffic accidents, and a total of 58,022 deaths in traffic accidents, posing a great threat to life safety. However, frequent traffic accidents are mainly due to people's dangerous driving. According to statistical analysis...
