Abstract

The invention relates to the technical field of automobile driving, can be applied to automatic driving vehicles, and particularly relates to a driving style identification method and device, the method comprises the following steps: obtaining each feature vector value of a target vehicle at each continuous moment, the feature vectors being used for representing the instantaneous driving state of the target vehicle, the feature vector comprises a state feature used for representing a state between the target vehicle and a related object thereof; sampling each feature vector value by taking continuous N values as a sampling unit to obtain a plurality of samples, N being a preset value; and determining the driving style of the target vehicle according to the plurality of samples. Based on the technical scheme provided by the invention, the driving style identification result can be more comprehensive and accurate.

Description

technical field [0001] The present application relates to the technical field of automobile driving, and in particular, to a driving style recognition method, an assisted driving method, an apparatus, a computing device and a storage medium. Background technique [0002] On the road, different drivers may have different driving styles, such as aggressive, smooth, cautious, etc. The driver may also be in some special dangerous driving states, such as drunk driving, drug driving, fatigue driving, etc. Driving style is closely related to dangerous driving behavior. Therefore, it is very important to accurately identify the driving style of surrounding vehicles for safe driving of the vehicle. [0003] Regarding the recognition of the driving style in the prior art, it is mainly the recognition of the driving style of the vehicle at present. The index value is calculated by collecting the driving state characteristics of the vehicle, and then the index value is compared with m...
