Abstract

The invention discloses a driving behavior recognition method and system, and relates to the technical field of automobile driving. The method comprises the following steps: segmenting driving behavior data by adopting a driving behavior sequence change point detection algorithm to obtain segmented driving behavior segments; calculating the confusion degree of the LDA models with different clustering numbers; performing comparing to obtain the minimum confusion degree; and inputting the driving behavior fragment characteristic frequency statistical matrix into an LDA model corresponding to theminimum confusion degree to obtain a driving behavior category. According to the method, the driving behavior data is segmented by adopting the driving behavior sequence change point detection algorithm, so that the driving behavior data can be segmented more accurately, and the formed driving behavior fragments are more complete; and measuring the LDA model by using the confusion degree, and obtaining the driving behavior category according to the LDA model with the optimal clustering number, wherein the obtained driving behavior category is more complete and comprehensive.

Description

technical field [0001] The invention relates to the technical field of automobile driving, in particular to a driving behavior recognition method and system. Background technique [0002] With the rapid development of automobile intelligent technology, the identification and prediction of driver behavior has become the key technology for establishing an advanced advanced driving assistance system (Advanced Driving Assistant System, ADAS), which can realize the full cooperative driving of the driver and the vehicle. Driving behavior recognition has been the subject of research from many different perspectives since the 1950s. Research has shown that driving behavior recognition can be applied in areas such as traffic flow modeling, road infrastructure optimization, traffic congestion prediction, establishment of advanced personalized driver assistance systems, and design of autonomous vehicles. [0003] At present, the research on vehicle driving behavior recognition methods...
