Driver road rage state vehicle-mounted recognition interaction system which takes physiological and control information into consideration

Abstract

The invention discloses a driver road rage state vehicle-mounted recognition interaction system which takes physiological and control information into consideration. The system comprises a physiological information monitoring module, a lateral operation monitoring module, a longitudinal operation monitoring module, a road rage state recognition module and an early warning interaction module, the driver physiological information monitoring module obtains dynamic data of a driver physiological signal, the lateral operation monitoring module monitors a lateral operation index characteristic used for representing a driver range emotion, the longitudinal operation monitoring module monitors a longitudinal operation index used for representing the driver range emotion, regarding the road rage recognition module, an off-line training and on-line recognition module of the driver rage emotion is constructed through a support vector machine machine-learning method, and the on-line recognition module is embedded into a vehicle-mounted control unit to recognize the driver rage emotion on line. In the driver road rage state vehicle-mounted recognition interaction system which takes the physiological and control information into consideration, the emotion state of a driver is detected in real time in the driving process, an early warning response is made timely, the driver rage emotion is relived, and surrounding drivers are prompted.

Description

technical field [0001] The invention relates to a vehicle-mounted driving assistance safety system, in particular to a vehicle-mounted recognition and interaction system for a driver's road rage state considering physiological information and control information. Background technique [0002] While the increase in the number of cars brings convenience to people, it also makes traffic congestion more and more serious. Among the many traffic accidents, the number of road traffic accidents caused by "road rage" has increased day by day in recent years. [0003] Due to the occurrence of objective events such as road congestion, traffic conflicts, and abnormal vehicle status during driving, when the driver perceives these stress changes, the activation level of the human body will quickly change, resulting in significant changes in the driver's heart rate, blood pressure, and muscle tension. Changes, thus causing a high degree of emotional stress and action stress. Due to the i...

Problems solved by technology

[0006] In order to solve the problems of low accuracy of road rage recognition during driving, poor universality, low detection accuracy using a single recognition index, and the inability to interactively remind surrounding traffic participants, the present invention builds a set of drivers based on physiological The on-board recognition and interaction system of road rage status and control information can detect the driver's emotional state in real time during driving, and make timely early warning responses to relieve the driver's anger to a certain extent and remind surrounding drivers
