Abstract

The invention relates to a driver behavior intention detection method fusing electroencephalogram signals, belongs to the technical field of intelligent driving, and solves the problems that detectionequipment in the prior art is interfered by the external environment and time delay exists in detection. The method comprises the following steps: constructing a virtual driving scene model, and synchronously acquiring an electroencephalogram signal and a behavior signal of a driver; Carrying out fusion analysis on the acquired behavior signal of the driver and the electroencephalogram signal toobtain a fusion analysis result; And obtaining an electroencephalogram signal of the driver in real time, predicting the driving intention of the driver according to the fusion analysis result, and performing auxiliary control on the vehicle control device. The driving intention of the driver is predicted and the driving behavior of the driver is controlled by using the fusion analysis result of the electroencephalogram signal of the driver and the behavior signal of the driver; The defect of existing driving behavior detection delay is overcome, corresponding changes of electroencephalogram signals of a driver in the driving process can be fully reflected, and accurate real-time control over the vehicle is guaranteed.

Description

technical field [0001] The invention relates to the technical field of intelligent driving, in particular to a method for detecting a driver's behavioral intention by fusing electroencephalogram signals. Background technique [0002] At present, road traffic injuries have become one of the important causes of death among people. About 95% of all kinds of motor vehicle accidents are caused to a certain extent by improper operation of drivers, while traffic accidents caused entirely by inappropriate driving behaviors of drivers Accidents accounted for three quarters of the total number of accidents. Therefore, it is very necessary to analyze the driver's behavior and driver's state. [0003] In order to improve driving safety, the existing research on assisted driving is mainly divided into two categories: one is to use on-board sensors (such as cameras, infrared detection, etc.) Take some control measures to prevent the vehicle from colliding with obstacles in front; the di...
