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 the dangerous driving state of a driver. The joint probability distribution model regarding the driving state value (hereinafter, called as DSV for short) of the driver energy storage condition and the temperature at a palm thenar is established; and the probability that the driver is in the dangerous driving state for a period of time in future when the palm thenar of the driver is at one certain temperature in the driving process is calculated, and if the probability is larger than one certain threshold value, warning information is sent out to prompt that the driver is in the dangerous driving state. According to the method and system for monitoring the dangerous driving state of the driver, the structure is simple, operation is convenient, the specificity and accuracy of pre-warning of the dangerous driving state are further improved through earlier forecast achievement for the dangerous driving state, and traffic accidents are avoided.

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 the driving state at home and abroad can be roughly divided into the following four types: [0003] (1) Characterize the driving state based on the driver's behavior characteristics (such as: head movement, eye movement, gaze direction, etc.), and its advantages are: non-contact, good physiological correlation, and international scientific basis. The disadvantages are: the signal acquisition is difficult, and the analysis technology is difficult. [0004] (2) To characterize the driving state based on the driver's physiological parameters (such as: EEG, ECG, respiratory conditions, muscle activity, etc.), the adv...
