Description
The present invention relates to a drowsiness driving notification system and a method thereof using a driver's sleeping time, and more particularly, to a drowsiness driving notification system using a driver's sleeping time to collect driver's fatigue and provide safe driving .
The number of traffic accidents is increasing as domestic annual auto sales exceed 1 million. As can be easily seen from the traffic accident statistics, most traffic accidents caused by drowsiness, which accounts for about 25% of all traffic accidents, are mostly caused by large-scale traffic accidents involving the center line. Unfortunately, A reliable technique that can prevent the occurrence of the problem is not popularized.
As a result, research and development are underway to prevent drowsiness.
As one example of the conventional technique, there is a method in which the threshold value is changed according to the brightness of the image of the driver's eye, the eye is determined to be in the open state if the threshold value is more than the threshold value, A method of reducing the false alarm based on the eye shape (shape difference according to the height direction) by using the moving average value of the opening / closing degree of closing the eyes is disclosed.
Conventionally, it is determined whether or not the eyes are closed by varying the threshold value in consideration of various factors necessary for shooting the eyes, or analyzing the degree of opening and closing of the eyes.
However, except for deliberately closing the eyes, the eyes closed state must be detected during a momentary motion such as blinking, so that the eye close state and the image acquisition timing do not necessarily coincide with each other.
In this way, conventionally, as the shutter speed of the camera or the image detection timing by the image processing ECU is shifted from the timing of closing the eyes, it is judged that the eyes that are actually closed are misaligned, It has been difficult to precisely detect the winding time and to accurately apply drowsiness driving prevention technology accordingly.
SUMMARY OF THE INVENTION The present invention has been made to solve the above problems and it is an object of the present invention to provide an accident prevention system for a drowsy driving system in which drowsiness can be induced during driving based on a sleeping time of a driver .
The present invention relates to a wearable device for collecting accumulated sleep time of a driver; And a sleep time collection unit that receives the accumulated sleep time of the driver from the wearable device, wherein the sleep time collection unit calculates a sleep time based on a cumulative sleep reference time of the driver, A sleep time determining unit for determining a sleeping warning signal of the driver based on the determined time and generating a sleeping warning signal of the driver based on the determined time; A controller for controlling the vehicle based on a sleeping warning signal of the driver; And a dispenser for dispatching a notice to the driver of a drowsiness alert signal of the driver.
And a driver monitoring unit for acquiring the biometric information of the driver in order to collect the driver's fatigue state based on the accumulative sleep time of the driver.
And can receive accumulated sleep time from any one or more of Bluetooth communication, mobile communication, and cloud computing.

The sleep time determination unit may generate the first warning signal when the sleeping time of the driver is greater than or equal to the set reference time, and may generate the second warning signal if the sleep time is less than or less than the set reference time.
The sleep time determination unit may transmit the first warning signal or the second warning signal to the dispatcher.
The control unit may control the set maximum output speed of the vehicle based on a sleeping warning signal of the driver.
The control unit may automatically reproduce the media device of the vehicle or control the air conditioner based on a sleeping warning signal of the driver.
The sleep time collecting unit stores the sleeping warning signal of the driver and can transmit it to the driver's terminal through telematics in order to feedback the start time of the sleeping warning.
In addition, the present invention provides a method for controlling a vehicle, comprising: receiving an accumulative sleep time of a driver; Determining that the driver arrives at a predetermined time or more from the time when the driver boarded the vehicle based on the accumulative sleep reference time of the driver and generating a sleeping warning signal of the driver based on the determined time; Controlling the vehicle based on a sleeping warning signal of the driver; And sending a notice to the driver of a sleeping warning signal of the driver.
The step of receiving the accumulated sleep time of the driver may further include acquiring the biometric information of the driver to collect the driver's fatigue state.
The generating of the driver's drowsiness warning guide signal may include generating a first warning signal if the driver's sleep time is greater than or equal to a set reference time and generating a second warning signal if the driver's sleep time is less than or less than the set reference time As shown in FIG.
The step of controlling the vehicle may further include the step of controlling the set maximum output speed of the vehicle based on a driver's sleeping warning signal.
The step of controlling the vehicle may further include the step of automatically regenerating the media device of the vehicle or controlling the air conditioner based on a sleeping warning signal of the driver.
The method may further include the step of storing the sleeping warning signal of the driver and transmitting to the driver's terminal through telematics in order to feedback the start time of the sleeping warning guidance.
