Dangerous steering behavior identification method based on boundary search

The invention provides a dangerous steering behavior recognition method based on boundary search, and the method employs the vehicle driving behavior data which can be obtained at present, carries out the analysis and calculation of a large amount of data, obtains a dangerous steering behavior recognition algorithm which is higher in adaptability and is more accurate in recognition, and can achieve the accurate recognition of a dangerous steering behavior. The basic thought of the method is as follows: firstly, establishing a steering behavior database containing dangerous steering behaviors and safe steering behaviors; each part of data in the steering behavior database comprises complete information of a steering behavior, such as lateral speed, longitudinal speed, lateral acceleration, roll angle, yaw velocity, steering wheel angle and the like of the vehicle; and then, based on the constructed steering behavior database, behavior characteristics are extracted by using a boundary search ...
