Abstract

The invention discloses a method for monitoring a driving road rage state. The method comprises the steps of acquiring a physiological signal data set of a driver, wherein the feature dimension of thephysiological signal data set is a first dimension; performing feature processing on the physiological signal data set to obtain a feature vector of the physiological signal data set; performing dimensionality reduction and feature extraction on the feature vector of the physiological signal to obtain a dimensionality reduction feature vector; constructing a driving road rage data set according to the dimensionality reduction feature vector; performing optimal feature acceleration selection on the driving road rage data set according to a recursive feature elimination method, and constructingand training a road rage recognition model; and monitoring the driver in real time according to the road rage recognition model. The method solves the problem of inaccurate road rage state recognition result in the prior art, and achieves the technical effects of reducing the response time required by driver road rage state recognition and achieving early warning and early intervention, thereby reducing safety accidents caused by road rage driving.

Description

technical field [0001] The present invention relates to the field of intelligent driving, in particular to a method and device for monitoring driving road rage state. Background technique [0002] Driver's road rage is a very important factor affecting safe driving at present, it is the driver's angry emotion caused by driving pressure and frustration in traffic jam. "Road rage" drivers will attack other people's cars, maliciously violate traffic rules, and cause traffic accidents. The research on road rage automatic detection and early warning technology has become an important part of active safety driving technology. In recent years, the research on road rage of drivers has received widespread attention, but most of the research focuses on how to avoid the occurrence of road rage from the aspects of psychology, policies, and regulations, and the research on automatic detection and recognition technology of road rage is relatively limited. few. [0003] However, in the ...
