Problems solved by technology

[0009] To sum up, the problem existing in the prior art is that none of the current methods for establishing the mapping relationship between physiological characteristics and driving state can directly reflect the energy reserve of the driver's brain and sympathetic nervous system. Specificity and accuracy need further improvement

Abstract

The invention belongs to the technical field of driving safety, and discloses a method and system for monitoring a driver's dangerous driving state, and establishes a combination of a driving state value (hereinafter referred to as the driving state value) and the temperature at the thenar point of the palm of the driver's energy reserve. Probability distribution model; calculate the probability of the driver being in a dangerous driving state in the future when the temperature at the thenar point of the driver's palm is a certain temperature during driving, and if the value is greater than a certain threshold, an alarm message will be issued; Prompt the driver to be in a dangerous driving state. The invention has simple structure and convenient operation, and can further improve the specificity and accuracy of early warning of the dangerous driving state by realizing the early warning of the dangerous driving state, thereby avoiding the occurrence of traffic accidents.

Description

Technical field [0001] The invention belongs to the technical field of driving safety, and in particular relates to an early warning method and system for a driver who is about to enter a dangerous driving state (driving fatigue, driving behavior disorder, blurred vision, etc.) during driving. Background technique [0002] At present, the methods for characterizing driving conditions at home and abroad can be roughly divided into the following four types: [0003] (1) Based on the driver's behavior characteristics (such as head movement, eye movement, gaze direction, etc.) to characterize the driving state, its advantages are: non-contact, good physiological relevance, and international scientific evidence. Disadvantages are: difficult signal acquisition, difficult analysis techniques. [0004] (2) Characterizing the driving state based on the driver's physiological parameters (such as EEG, ECG, breathing status, muscle activity, etc.). The advantage is that the signal is easy to ob...
