Abstract

The present invention relates to a driving style recognition method, which comprises the following steps: step S1: using a sensor to collect driving trajectory data; step S2: based on the driving trajectory data, combined with geographical information data to obtain relative speeding behavior; step S3: based on relative speeding behavior , to obtain the driving style parameters; step S4: based on the driving style parameters, use a clustering algorithm to identify the driving style. Compared with the existing technology, the data accuracy requirements for driving style recognition are relaxed. Based on low-frequency data, it is beneficial to reduce the data collection cost of driving style recognition; it expands the application of low-frequency driving trajectory data in driving style exploration; it can improve road traffic. safety.

Description

technical field [0001] The invention relates to the field of driving style recognition, in particular to a driving style recognition method. Background technique [0002] Driving style is an overall evaluation index that characterizes the driver's inherent driving style. Driving style research mainly divides drivers from the perspectives of energy-saving driving and traffic safety. Existing studies have shown that the driver's style is closely related to traffic safety: drivers with aggressive driving styles have bad driving behaviors such as frequent lane changes, rapid acceleration and deceleration, and close-distance car following, which are likely to increase the probability of accidents. Through the study of driving style, the detection or feedback of the bad driving style of the driver's daily driving can realize the supervision and education of the driver's driving behavior, and assist with corresponding measures to improve driving safety. [0003] The data for driv...
