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

Embodiment Construction
[0034] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0035] The application principle of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0036] Such as figure 1 As shown, the early warning method for preventing the occurrence of a dangerous driving state during the driving process of the driver provided by the embodiment of the present invention includes:
[0037] S101: Before the driver uses the system for the first time, the driver conducts a dynamic driving state value and the temperature monitoring at the thenar point of the palm, and uses the obtained driving state value and the temperature data at the thenar poin...

The invention belongs to the technical field of driving safety, and discloses a device for judging whether or not a driver is going to be in dangerous driving states such as fatigue driving and blurred vision. The device comprises a sound-light alarm unit, a vibration alarm device, a palm temperature collecting device, a computing unit and a probability model unit which are electrically connected, and a joint probability distribution model for a driving state value relating to driver energy storage states (hereinafter referred to as a driving state value) and temperature at the greater thenar of the palm is built; the probability that when the temperature of the greater thenar of the palm of the driver is te, the driver is in a dangerous driving state in the next period of time is computed, and if the value is larger than a threshold value, alarm information is sent out; it is prompted that the driver is in a dangerous driving state. The device is simple in structure and convenient to operate, by forecasting the dangerous driving state earlier, the specificity and accuracy of dangerous driving state early warning are improved, 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 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 advantage is t...
