종래의 졸음 운전방지용 비상운전장치는 제어화면을 통해 차량의 진행방향과 안전운행 방향간에 차이가 있을 경우 경보용 부저를 울려 졸고 있는 운전자를 깨워주거나 간단한 운전맵(MAP)을 설정하여 스티어링 휘일(STEERING WHEEL : 이하 "운전대"라 한다)로만 방향을 조정하였다. 그러나 비상 운전작동시 이러한 운전대만으로 방향을 조정하는 것은 차량의 상태 및 차량의 종류에 따라 방향 전환 맵(MAP) 설정에 어려움(예를 들면 UNDER STEERING, OVER STEERING)이 많았다.Conventional drowsy driving device for preventing drowsy driving wakes up the driver dozing off the alarm buzzer or sets a simple driving map (MAP) when there is a difference between the driving direction and the safe driving direction through the control screen. WHEEL: The direction was adjusted only with "wheel". However, in the emergency driving operation, it was difficult to set the direction change map (MAP) according to the condition of the vehicle and the type of vehicle (eg, UNDER STEERING, OVER STEERING).

본 발명은 상기와 같은 문제점을 개선하고자 창안된 것으로, 비상 운전시 차량의 상태 및 차종에 따른 운전 맵 설정이 용이한 졸음 운전 방지용 비상운전 장치를 제공하는데 그 목적이 있다.The present invention was devised to improve the above problems, and an object thereof is to provide an emergency driving device for preventing drowsy driving, which is easy to set a driving map according to the state and type of vehicle during an emergency driving.

제 1도는 본 발명에 따른 졸음 운전 방지용 비상 운전장치의 개략적 블록도이다.1 is a schematic block diagram of an emergency operation apparatus for preventing drowsy driving according to the present invention.

이하 도면을 참조하면서 본 발명에 따른 졸음 방지용 비상운전장치를 상세하게 설명한다.With reference to the drawings will be described in detail the emergency operation device for preventing drowsiness according to the present invention.

제 1도는 본 발명에 따른 졸음 운전방지용 비상 운전장치의 개략적인 블록도이다. 도시된 바와같이, 본 발명에 따른 졸음 방지용 비상운전장치는 방향각 감지센서(10), 제어화면 표시부(40), 운전맵을 설정하는 제어수단(50), 운전맵을 설정하는 제어수단(50), 경보용 부저(60), 비상 운전액츄에이터(70) 및 기어박스(80)를 구비한다.1 is a schematic block diagram of an emergency operation apparatus for preventing drowsy driving according to the present invention. As shown, the emergency operation apparatus for preventing drowsiness according to the present invention, the direction angle sensor 10, the control screen display unit 40, the control means 50 for setting the driving map, the control means 50 for setting the driving map ), An alarm buzzer 60, an emergency operation actuator 70, and a gear box 80.

여기서, 방향각 센서(10)는 타이로드부(20)에 내장되어 타이어(30)의 방향각을 감지하고, 제어화면 표시부(40)는 차량의 현재 진행방향(42)과 차선(41)에 따른 안전 운행진로(43)를 비교하며, 제어수단(50)에 의해 감지된 차선(41)에 따른 차량 진행방향(42)의 어긋남을 비교하여 운전맵을 설정한다. 그리고, 경보용 부저(60)는 제어수단(50)의 지시에 따라 경보음을 울려 졸고 있는 운전자를 깨우거나, 운전자에게 안전운행을 하도록 경각심을 일깨우고, 비상 운전 액츄에이터(70)는 경보음이 울려도 운전자가 졸고있어 차량의 진행방향에 아무런 변화가 없을 경우에 이를 감지한 제어수단(50)의 지시에 따라 운전대를 강제로 조작하게 되는데, 기어박스(80)는 비상운전 액츄에이터(70)의 작동에 따라 운전대(90)를 강제로 조작하여 차량운행이 안전운행이 되도록 한다.Here, the direction angle sensor 10 is embedded in the tie rod unit 20 to detect the direction angle of the tire 30, the control screen display unit 40 is in the current traveling direction 42 and the lane 41 of the vehicle The safety driving path 43 is compared, and the driving map is set by comparing the deviation of the vehicle traveling direction 42 according to the lane 41 detected by the control means 50. Then, the alarm buzzer 60 wakes up the driver who snoozes an alarm sound according to the instruction of the control means 50, or wakes up the alert to make the driver safely run, and the emergency operation actuator 70 sounds an alarm sound. Also, when the driver is dozing and there is no change in the direction of movement of the vehicle, the steering wheel is forcibly operated according to the instruction of the control means 50 which detects this, and the gearbox 80 operates the emergency driving actuator 70. By manipulating the steering wheel 90 according to the driving to ensure safe driving.

이상과 같은 구성의 졸음 방지용 비상 운전장치는 비상운전 작동에 있어서는 운전대(90)로 조작하지만 운전방향을 결정하기위한 운전맵(MAP)의 설정은 타이로드부(20)의 방향각 감지센서(10)에서 감지한 타이어(30)의 방향각 및 제어화면 표시부(40)에서 감지된 차량 진행방향(42)의 차선(41)에 따른 안전운행 진로(43) 이탈 정도를 비교하여 운전맵을 설정함으로써, 차량의 상태 및 차종에 관계없이 정확한 운전맵을 설정할 수 있다. 따라서 본 발명의 졸음 방지용 비상 운전장치는 다음과 같이 동작한다.The drowsiness emergency driving device for preventing drowsiness is operated by the steering wheel 90 in the emergency driving operation, but the setting of the driving map MAP for determining the driving direction is the direction angle sensor 10 of the tie rod part 20. By setting the driving map by comparing the degree of departure of the safe driving course 43 according to the lane 41 of the vehicle driving direction 42 detected by the direction angle of the tire 30 and the control screen display unit 40 detected by the In addition, it is possible to set an accurate driving map regardless of the vehicle state and vehicle type. Therefore, the emergency operation apparatus for preventing drowsiness of the present invention operates as follows.

먼저, 제어화면 표시부(40)의 제어화면을 통해 현재 진행방향(42)과 차선(41)에 따른 안전운행 진로(43)에 차이가 있음이 판단될 경우, 제어수단(50)은 1차로 경보용 부저(60)를 울려 졸고 있는 운전자를 깨우거나, 운전자에게 안전운전에 대한 경각심을 일깨워 안전운행을 하도록 한다. 이와같이 경보음을 울려도 차량 진행 방향에 아무런 변화가 없다(운전자가 계속해서 졸고 있는 경우를 말한다)고 판단되면, 제어수단(50)은 2차로 비상운전 액츄레이터(70)에 지시하여 강제로 운전대를 조정하도록 한다. 이러한 운전대의 강제 조정은 액츄에이터(70)의 동작에 따라 기어박스(80)의 기어들에 의해 이루어진다.First, when it is determined that there is a difference between the current driving direction 42 and the safe driving course 43 according to the lane 41 through the control screen of the control screen display unit 40, the control means 50 firstly alarms. Dragon buzzer (60) to wake up the driver dozing, or wake up the driver to be alert for safe driving to make safe driving. When it is determined that there is no change in the vehicle traveling direction even when the alarm sounds in this way (the case where the driver continues to doze), the control means 50 instructs the emergency driving actuator 70 secondly to force the steering wheel. To adjust it. This steering force adjustment is made by the gears of the gearbox 80 according to the operation of the actuator 70.

이상 설명한 바와같이, 본 발명에 따른 졸음 운전 방지용 비상 운전장치는 타이어의 방향각을 감지하고, 차량의 진향방향과 차선에 따른 안전 운행진로를 비교에 의한 차량 진행방향의 어긋남의 정도를 판단하여 운전맵을 설정하되, 졸음 운전이라 판단될 경우 1차로 경보음을 울려 운전자를 깨우고, 그래도 차량의 진행방향에 아무런 변화가 없다고 판단될 경우 상기 운전 맵에 따라 운전대를 강제로 조작함으로써, 비상운전 시간을 단축할 수 있고, 운전의 안전성을 증대되며, 운전맵 설정이 용이한 장점이 있다.As described above, the emergency driving device for preventing drowsiness driving according to the present invention detects the direction angle of the tire and determines the degree of the deviation of the vehicle traveling direction by comparing the driving direction of the vehicle and the safe driving path according to the lane. Set up the map, but if it is determined that it is drowsy driving, wake up the driver by sounding an alarm first, and if it is determined that there is no change in the direction of travel of the vehicle by forcibly manipulating the steering wheel according to the driving map, It is possible to shorten, increase safety of driving, and easily set driving map.
