Abstract

The invention provides a driving behavior analysis method and system, and the method comprises the steps: obtaining driving data of a vehicle sensor and a vehicle CAN, and fusing the driving data based on the timestamp of a reference sensor; dividing a driving scene, analyzing an association relationship between the driving scene and the driving data, and extracting data fragments from the fused data; extracting target feature values from the data fragments, solving a Weber distribution parameter of each feature value, performing equidistant binning on the feature values, solving quantiles in each box body, connecting the same quantiles in each box body, and obtaining a Weber distribution curve corresponding to the feature values through linear regression fitting; and drawing a scatter diagram of each driving scene, and taking the feature data distributed in the predetermined interval range as a behavior dense area in the corresponding scene to obtain driving behavior features in different driving scenes. Therefore, the driving behavior analysis process can be simplified, the accuracy of the analysis result is guaranteed, huge workload in the traditional analysis model training process is avoided, and the analysis efficiency is guaranteed.

Description

technical field [0001] The invention belongs to the field of automatic driving, and in particular relates to a driving behavior analysis method and system. Background technique [0002] With the rapid development of smart cars, the diverse functions of cars can meet people's daily needs, and autonomous driving is gradually becoming a reality. Although self-driving cars can meet user-based driving requirements, however, for users in different countries and regions, due to differences in traffic rules, traffic environments, and geographical environments, there are certain differences in their driving habits. For the uniformly developed automatic driving system, it is difficult to adjust the functional parameters in a targeted manner according to the driving habits of users in different regions. [0003] At present, the more common method is to build a driving behavior analysis model based on deep learning algorithms, input the collected driving data and marked scenes into the...
