Analysis method and device of driving behavior

The invention discloses an analysis method and device of driving behavior, and relates to the technical field of electronic information. Through the adoption of the analysis method and device, the high efficiency and real-time performance of real-time monitoring and intelligent evaluation are guaranteed, and besides, the cost is reduced. The analysis method disclosed by the invention comprises the following steps that a main processor obtains three-axis acceleration and three-axis angular velocity of a vehicle in the moving process through connected sensors; attitude angle data of the vehicle in the moving process is obtained according to velocity data, wherein attitude angles include the yaw angle of the vehicle, the roll angle of the vehicle, and the pitch angle of the vehicle; mathematic models which express states of motion are established according to the velocity data and the attitude angle data, wherein the mathematic models at least include an actual yaw angle model and an acceleration model in the actual driving direction; the driving behavior of a driver of the vehicle is determined according to the established mathematic models. The method disclosed by the invention is suitable for the analysis of the driving behavior.
