Description
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a system and a method for preventing drowsiness in a vehicle, and more particularly, to a drowsiness prevention system and a method for preventing a driver from drowsily driving a vehicle.
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.
It is an object of the present invention to provide a system and method for preventing drowsiness in a vehicle in which a driver warns a driver in advance of drowsy driving, have.
In order to achieve the above object, the present invention provides a drowsy detection unit mounted on a shift lever of a vehicle, the drowsiness detection unit measuring a biometric information of a driver; When the biometric information of the driver is input from the drowsy detection unit, the biometric information is compared with a predetermined reference value, and it is determined whether or not the driver is likely to drive the drowsy according to the comparison result. ; And an output unit for receiving a control signal from the control unit and outputting a determination result of the control unit to the outside.
Further, the drowsiness detecting unit is mounted on an upper portion of a shift lever of the vehicle.
Further, a guide groove is formed on an upper portion of the shift lever of the vehicle so that a driver's finger is guided, and the drowsiness sensing unit is mounted in the guide groove.
Further, the guide groove is formed of an elastic material so that the shape of the guide groove changes according to the size of the driver's finger.
In addition, the biometric information of the driver measured by the drowsiness sensing unit includes any one selected from the pulse wave of the driver, blood pressure, body temperature, and oxygen saturation.
Further, the output unit receives a control signal from the control unit and emits light.
Further, the output unit receives a control signal from the control unit and outputs a sound.
Wherein the control unit outputs the biometric information of the driver input from the drowsy detection unit to the output unit and the output unit outputs the biometric information of the driver received from the control unit in numerical or character form System.
Wherein the drowsiness sensing unit and the output unit are respectively provided on the upper portion of the shift lever of the vehicle and the drowsiness sensing unit is positioned in a direction opposite to the driver and the output portion is positioned in a direction facing the driver. Provide a driving prevention system.
Further, the present invention provides a system for preventing drowsiness in a vehicle, wherein the output unit is provided on a navigation or instrument panel mounted on a dashboard of the vehicle.
The controller may further include a start detecting unit for detecting a start of the vehicle and generating a speed sensing signal. The controller controls the drowsiness sensing unit to be activated when the start sensing signal is received from the start sensing unit Thereby providing a drowsiness prevention system for a vehicle.
In addition, the control unit may include a boot detection process for determining whether the vehicle is started up; In the start sensing process, when the start of the vehicle is turned on, the controller activates the drowsiness sensing unit mounted on the shift lever of the vehicle to input the biometric information of the driver measured by the drowsiness sensing unit to the control unit. Information measurement process; Wherein the control unit compares the biometric information input from the drowsy detection unit with a preset reference value and determines whether the driver is likely to drive the drowsy according to the comparison result; And a signal output step of outputting a control signal to the output unit and controlling the driver to inform the driver of the current state of the driver, when it is determined in the determining process that there is a possibility of driving the driver to sleepy Thereby preventing a drowsiness in the vehicle.
Further, the signal outputting step may include: a step of outputting light to the outside, the output part receiving the control signal from the control part.
In addition, the signal outputting process may include: the output unit receiving a control signal from the control unit generates sound to the outside.
In the present invention, when the driver touches the body of the driver to the drowsiness detecting unit, the current state of the driver is checked using the biometric information of the driver measured by the drowsiness detecting unit, There is an effect that the driver is alerted in advance to the sleeping drive before the driver makes the sleeping drive of the driver in advance.
In addition, since the guide groove in which the drowsiness sensing unit is located and the output unit that indicates the driver's current state are provided on both sides of the upper portion of the shift lever of the vehicle, when the driver holds the shift lever of the vehicle, It is easily guided to the guide groove so as to be contacted, and the driver can easily recognize light or sound output from the output unit.
Further, since the guide groove is formed of an elastic material so that the shape of the guide groove is changed according to the size of the driver's finger, the driver can easily guide his or her finger to the guide groove regardless of the size of the user's finger It is effective.
In addition, an output unit is provided on the dashboard of the vehicle, so that the driver can easily check his / her biometric information in real time, thereby awakening the alertness of the sleepy driving and preventing the sleepy driving in advance.
