Traffic accidents are also increasing with the recent increase in the number of vehicles, and drowsiness driving is one of the main causes of traffic accidents. Accidents caused by drowsiness are more dangerous because the vehicle can not be controlled as the driver's cognitive ability drops significantly at the time of the accident. Especially, accidents caused by drowsiness on the highway lead to major accidents.

Drowsy driving sensing technologies have been developed to detect drowsy driving, and some technologies have been applied to commercial vehicles. Such drowsiness driving detection techniques include, for example, a method of analyzing a driver's blinking speed using a camera, and a method of analyzing a driving pattern of a vehicle. The drowsiness prevention system using the camera blinking speed analysis method is the most representative system introduced by the advanced automobile makers. It uses the blinking speed of the eyes when the driver drives the drowsy, If it falls below a certain level, it is a dormant driving system and warns the driver. However, the drowsiness driving prevention system using a camera has a problem that when the driver wears sunglasses, drowsiness driving is difficult to be detected, and the interior lighting of the vehicle is greatly affected.

The driving pattern of the vehicle and the analysis method of the steering wheel operation pattern of the driver can detect the lane departure by the camera attached to the outside of the vehicle using the wobble of the driver when the driver is sleeping driving, It is a method of using the movement of the steering wheel. Since this method detects the driving pattern of the vehicle, there is an advantage that it is possible to prevent a collision accident with a nearby vehicle by automatically adjusting the running direction of the vehicle in an emergency situation. However, there is a problem that it is difficult to accurately detect drowsiness driving because the driving pattern of the vehicle changes according to surrounding conditions such as bad weather or road surface condition.

In addition, these methods determine the drowsy driving state in a state where the driver has advanced to the step of drowsing, so that the drowsiness driving can not be prevented in advance and the risk of an accident must be taken.
