Abstract

The invention discloses a driving behavior sensing method based on information fusion and system thereof. The method includes the following steps of collecting acceleration, vehicle speed and course angle of a vehicle by means of a sensor assembly integrated on the vehicle; according to the acceleration, the vehicle speed and the course angle, conducting horizontal alignment and course alignment on a vehicle coordinate system and detecting the alignment results; according to the acceleration, the vehicle speed and the course angle, judging whether or not behaviors such as speed increase, speedreduction, steering and collision happen to the vehicle, and recording and uploading related data if yes. The acceleration, the vehicle speed, the course angle and other different kinds of vehicle data of the vehicle are obtained through an acceleration meter (namely a gyroscope or a compass), a GPS module and the like. The acceleration, angular velocity, a magnetic direction and other multidimensional data such as the course angle, the height and the vehicle speed in a GPS can be utilized for fusion analysis, the probability of misdetection and measurement omissions is substantially decreased, and complete data during occurrence of an event can be accurately recorded to provide bases for further analysis.

Description

technical field [0001] The invention relates to the technical field of driving behavior data analysis, in particular to a driving behavior perception method and system based on information fusion. Background technique [0002] With the popularity of private cars, driving behavior is related to the normal traffic order and the personal and property safety of drivers. Drivers need standards and guidance that can quantify their own driving skills. Due to the development of Internet of Vehicles technology, obtaining and analyzing and evaluating driving behavior information has become an important requirement. Driving behavior analysis can not only help car owners understand their own driving behavior and improve driving habits, but can also be used in car insurance and fleet management. For example, the auto insurance industry can customize insurance premiums according to the quality of driving behavior, and the fleet can evaluate the level of safe driving based on the driver's...
