Background

The traffic accident easily caused by fatigue driving refers to the phenomenon that after a driver drives a vehicle continuously for a long time, the physiological function and the psychological function are disordered, and the driving skill is objectively reduced. The driver has poor or insufficient sleeping quality, and is easy to have fatigue when driving the vehicle for a long time. Driving fatigue affects the driver's attention, feeling, perception, thinking, judgment, consciousness, decision and movement. When the vehicle is driven continuously after fatigue, the vehicle can feel sleepy, weak limbs, unconsciousness, reduced judgment capability, even absentmindedness or instant memory loss, delayed or early action, improper operation pause or correction time and other unsafe factors, and road traffic accidents are easy to happen. Thus, driving the vehicle after fatigue is strictly prohibited. In particular, fatigue driving is likely to occur during high-speed driving.

When a vehicle is driven, the driver can have driving fatigue phenomena of different degrees along with the increase of the speed or the continuous high-speed driving. When a vehicle is driven at a high speed, the attention of a driver is concentrated and the driver is always in a state of high mental stress, and the driver gradually feels tired along with the continuous increase of the speed and the prolongation of the driving time. When the vehicle runs on an expressway, the road environment is single, the traffic interference is less, the speed is stable, the noise and the vibration frequency in the running process are low, and the vehicle is easy to make a driver feel monotonous and sleepy, so that the expressway hypnosis phenomenon is generated.
