If you hear a certain beep to prevent driving The key is characterized by consisting of a warning sound generating unit (7).

이와같이 구성된 본 발명 스티어링 휠의 장력 측정장치의 동작에 대하여 설명하면 다음과 같다.Referring to the operation of the tension measuring device of the present invention the steering wheel configured as described above is as follows.

본 발명에 있어, 운전자가 스티어링 휠(1)을 잡은 상태에서 차량을 운 행시키고자 하는 경우, 상기 스티어링 휠(1)의 스포크에 다수 장착된 접촉감지부재(예; 고정저항)(2)에서는 스티어링 휠(1)에 접촉되어 있는 운전자 손의 접촉상태를 감지하게 된다.In the present invention, when the driver wants to drive the vehicle while holding the steering wheel 1, the contact sensing member (e.g., fixed resistance) 2 mounted on the spokes of the steering wheel 1, The driver's contact with the steering wheel 1 is detected.

그리고, 상기 접촉감지부재(2)에 의해 감지된 손의 접촉상태에 따라 다수의 탄성체(3)에서는 탄성작용을 하면서 손의 접촉상태에 따른 장력을 발생시키게 되고, 상기 발생된 장력은 스티어링 휠(1)의 내부 림에 다 수 장착된 장력측정부재(예; 가변저항)(4)에 의해 측정되므로서, 운전 자의 상태를 인식하게 되는 것이다.In addition, according to the contact state of the hand sensed by the touch sensing member 2, the plurality of elastic bodies 3 generate elasticity according to the contact state of the hand while acting elastically. As measured by the tension measuring member (eg, variable resistance) 4 mounted on the inner rim of 1), the driver's state is recognized.

즉, 운전자가 의식을 잃거나 졸음운전을 하는 경우, 또는 손이 떨리게 되면서 스티어링 휠(1)을 잡고 있는 손의 근육힘이 풀리면, 상기 접촉 감지부재(2)에서는 상기 설명된 상태에 따라 스티어링 휠(1)에 접촉된 손의 접촉상태변화를 감지하게 되고, 상기 감지된 손의 접촉상태변화에 따라 탄성체(3)에서는 탄성작용을 실시하게 되므로서, 상기 스티어링 휠(1)에 접촉된 손의 접촉상태변화에 따른 장력을 발생시키게 되는 것 이다.That is, when the driver loses consciousness or makes a drowsy driving, or when the muscle force of the hand holding the steering wheel 1 is released while the hand is shaken, the contact sensing member 2 uses the steering wheel according to the state described above. The contact state of the hand in contact with (1) is detected, and the elastic body 3 performs elasticity according to the detected change in the contact state of the hand, so that the contact of the hand in contact with the steering wheel 1 Tension is generated according to the change of contact state.

이때, 상기 스티어링 휠(1)에 접촉된 손의 접촉상태변화에 의해 발생된 장력은 신호변환부(4)에 의해 디지털 또는 아날로그 신호로 변환되어 ECU(6)에 출력되고, 상기 ECU(6)에서는 변환되어 입력된 디지털 또는 아날로그 신호에 따라 현재 운전자가 의식을 잃거나 졸음운전을 하는 경우, 또는 손이 떨리고 있음을 인식한 후, 경고음 발생부(7)를 제어 하게 된다.At this time, the tension generated by the change in the contact state of the hand in contact with the steering wheel 1 is converted into a digital or analog signal by the signal conversion unit 4 is output to the ECU (6), the ECU (6) In accordance with the converted digital or analog signal in the current driver when the driver loses consciousness or drowsiness, or after recognizing that the hand is shaking, and controls the warning sound generating unit (7).

그리고, 상기 경고음 발생부(7)에서는 ECU(6)의 제어에 따라 운전자가 의식을 찾을수 있도록 하거나 또는 운전자의 졸음운전을 경고하도록 일정경고음을 발생시켜, 이를 운전자에게 알려주는 것이다.The warning sound generating unit 7 generates a predetermined warning sound to inform the driver of the driver's drowsiness or warns the driver's drowsy operation under the control of the ECU 6.

여기서, 상기 ECU(6)에서는 운전자의 상태 즉, 의식을 잃거나 졸음운전 일 경우를 대비하여 차량의 시스템을 제어하므로서, 차량사고를 미연에 예방하게 되는 것이다.In this case, the ECU 6 controls the system of the vehicle in preparation for a driver's state, that is, loss of consciousness or drowsy driving, thereby preventing a vehicle accident in advance.

이상에서 설명한 바와같이 본 발명은 운전자가 잡는 차량의 스티 어링 휠에 손의 장력을 측정하는 시스템을 구성시키므로서, 측정된 손의 장력에 따라 운전자의 운전상태를 파악한 후, 경고음을 발생시켜 이를 운전자에게 알려주므로서, 운전자의 졸음운전을 예방하여 졸음운전 에 따른 차량의 사고를 미연에 방지하는 효과가 있는 것이다.As described above, the present invention configures a system for measuring the tension of the hand on the steering wheel of the vehicle that the driver grasps, and after grasping the driver's driving state according to the measured tension of the hand, generates a warning sound and generates a warning sound. By notifying the driver, the driver's drowsy driving is prevented, thereby preventing the accident of the vehicle caused by the drowsy driving.
