Problems solved by technology

[0003] However, the fatigue driving detection in the prior art is difficult to judge whether the driver is in a fatigue driving state based on the driver's facial features and the number of nods and in conjunction with the external truth road condition detection and driving state. The detection method is relatively simple, so the detection effect Not ideal, so needs to be improved

Abstract

The invention discloses a fatigue driving aid device, which comprises an information collector, an infrared CCD camera, a capacitance sensor, an ordinary CCD camera, a driving state detection module,a signal amplifier, an A / D converter, a DSP processor, an alarm, a brake module and a data memory, wherein the infrared CCD camera is arranged between an auto windshield and an interior mirror; the output end of the infrared CCD camera is electrically connected with the input end of a signal collector for collecting the blink frequency, the blink time and the yawn frequency of an auto driver and transmitting the above information to the signal collector. The infrared CCD camera arranged between the auto windshield and the interior mirror is used for collecting the blink frequency, the blink time and the yawn frequency of the auto driver, the nodding times of the auto driver can be collected with the help of the capacitance sensor arranged at the inner top part of the auto, and the fatiguedriving state can thus be detected.

Description

technical field [0001] The invention belongs to the technical field of fatigue driving assistance devices, and in particular relates to a fatigue driving assistance device. The invention also relates to a fatigue driving assistance device and a fatigue driving detection method. Background technique [0002] Driving fatigue refers to the phenomenon that the driver's physiological function and psychological function are out of balance after driving continuously for a long time, and the driving skill declines objectively. The driver's sleep quality is poor or insufficient, and he is prone to fatigue after driving for a long time. Driving fatigue will affect the driver's attention, feeling, perception, thinking, judgment, will, decision and movement, etc., so fatigue driving can easily lead to driving accidents. [0003] However, the fatigue driving detection in the prior art is difficult to judge whether the driver is in a fatigue driving state based on the driver's facial fea...
