또한, 자동차를 주행 시 다른 차선으로 운행중인 자동차가 고속으로 추월을 수행하는 경우에는 자동차의 좌우 양측에 기압차가 발생하면서 핸들쏠림현상이 발생하게 된다. In addition, when a vehicle driving in a different lane performs overtaking at a high speed while driving a vehicle, steering wheel phenomenon occurs while a pressure difference occurs on both sides of the vehicle.

이로 인하여 종래에는 자동차를 주행시 전방 또는 좌측이나 우측으로부터 가해지는 풍량에 의해 차체가 좌우로 기울어져 정속주행을 할수 없게 됨은 물론, 외부의 풍량에 의해 자동차의 주행상태가 불안해져 안락한 주행이 이루어지지 않게되는 문제점이 있었다.As a result, the vehicle body is inclined left and right due to the amount of wind applied from the front or the left or the right when driving the vehicle, and thus the vehicle cannot be driven at constant speed. There was a problem.

또한, 종래에는 자동차를 주행 시 타 차량에 의해 좌우 양측에 기압차가 발생하는 경우에는 핸들쏠림현상이 발생하여, 자동차를 주행시 정확한 조향이 이루어 지지 않게 되는 등의 문제점이 있었다. In addition, in the related art, when an air pressure difference occurs on both sides of the vehicle by another vehicle while driving, the steering wheel may occur, and thus the vehicle may not be steered correctly when the vehicle is driven.

본 발명의 자동차의 주행안전성 유지장치는 도 1과 도 2에 도시하고 있는 바와 같이, 자동차의 주행속도가 핸들쏠림 및 롤링이 발생할 수 있는 기준속도 이상인 경우에는 감지센서(100)에 의해 자동차의 좌측풍압과 우측풍압 및 전방좌우측의 풍압이 자동차의 전방 좌우 양측에 각각 설치되어 있는 한쌍의 피토관(200)을 통해 측정되고, 상기 피토관(200)을 통해 측정된 풍압은 제어부(300)로 입력되어 자동차의 좌측 및 우측의 압력차를 비교하게 되며, 상기 제어부(300)에서 비교 판단된 좌우 양측의 풍량의 압력차가 핸들쏠림 및 롤링발생기준값보다 크면 일정시간동안 스티어링컬럼이 일정시간동안 록킹되도록 전자스티어링컬럼록(400)이 작동됨과 동시에 풍압이 높은 방향의 일측 댐핑포스가 일정시간동안 상승되어 롤링이 발생되지 않도록 전자제어현가장치(500 : ECS)가 작동 된다.As shown in FIGS. 1 and 2, the apparatus for maintaining driving safety of the vehicle of the present invention is provided by the sensor 100 when the driving speed of the vehicle is greater than or equal to a reference speed at which steering wheel rolling and rolling may occur. The wind pressure and the right wind pressure and the wind pressure on the front left and right sides are measured through a pair of pitot pipes 200 installed on both front left and right sides of the car, and the wind pressures measured through the pitot pipes 200 are inputted to the control unit 300 and the vehicle. The pressure difference between the left and right sides of the control unit 300, and the electronic steering column to lock the steering column for a certain period of time if the pressure difference of the air volume of the left and right sides determined by the control unit 300 is greater than the handle pull and rolling generation reference value. At the same time as the lock 400 is operated, one side damping force in the direction of high wind pressure is raised for a predetermined time so that rolling does not occur. (500: ECS) is activated.

여기에서 상기 피토관(200)은 도 3에 도시하고 있는 바와 같이 자동차의 전면방향에 발생되는 풍향이 유입되는 전면공기유입관(210)과 자동차의 측면 풍향이 유입되는 측면유입관(220)이 연통되게 형성되어 있어, 자동차를 주행시 자동차의 전면방향과 측면 방향의 풍향을 동시에 측정할 수 있게 됨을 밝혀 둔다.Here, as shown in FIG. 3, the pitot tube 200 communicates with the front air inflow pipe 210 through which the wind direction generated in the front direction of the vehicle flows and the side inflow pipe 220 through which the side wind direction of the vehicle flows. It is formed so as to be able to measure the wind direction in the front direction and the side direction of the vehicle at the same time driving the car.

한편, 상기 피토관(200)은 자동차의 전면에 설치되는 프론트범퍼의 좌우 양측에 각각 설치되어, 자동차를 주행시 자동차의 전면방향과 좌우측 방향에 발생하는 풍향이 직접 피토관(200)의 내부로 유입되어 지도록 함이 더욱 바람직 함을 밝혀 둔다.On the other hand, the pitot pipe 200 is respectively installed on both the left and right sides of the front bumper installed on the front of the car, so that the wind direction generated in the front direction and left and right direction of the car when driving the car directly flows into the inside of the pitot pipe 200 It turns out that it is more preferable.

또한, 상기 전자스티어링록(400)에 의해 록킹되는 스티어링컬럼(600)의 외측부에는 도 4에 도시하고 있는 바와 같이, 전자스티어링콜럼록(400)의 록바(410)가 인입되는 록링홀(710)이 외측부에 내삽지게 형성되어 있는 스플라인 타입의 록링(700)이 결합되어 있어, 자동차를 운행중 자동차의 좌우 양측에 풍압차가 발생하여 제어부(300)에서 핸들쏠림방지제어신호가 출력되면, 상기 스티어링컬럼(600)을 록킹시키기 위해 전자스티어링컬럼록(400)의 록바(410)가 모터(미도시)의 구동력에 의해 외부로 인출되고, 상기 모터에 의해 인출되는 록바(410)는 록링(700)의 록링홀(710)에 삽입되는 것에 의해 스티어링컬럼(600)을 록킹시켜 핸들쏠림현상이 발생하지 않도록 하게 된다.In addition, as shown in FIG. 4, a locking bar 710 into which the lock bar 410 of the electronic steering column lock 400 is retracted is formed at an outer portion of the steering column 600 which is locked by the electronic steering lock 400. The spline-type lock ring 700 is inserted into the outer portion is coupled, when the wind pressure difference occurs on both the left and right sides of the vehicle while driving the vehicle, when the steering wheel control signal is output from the controller 300, the steering column ( The lock bar 410 of the electronic steering column lock 400 is drawn out to the outside by a driving force of a motor (not shown) to lock the lock 600, and the lock bar 410 drawn by the motor is locked of the lock ring 700. The steering column 600 is locked by being inserted into the ring hole 710 so that the handle pull phenomenon does not occur.

이때, 상기 록바(410)는 안전운행에 지장이 없는 범위의 짧은 시간동안만 록링홀(710)에 인입이 이루어지면서 스티어링컬럼(600)을 록킹하게됨을 밝혀 둔다.At this time, the lock bar 410 is revealed that the locking column 410 is locked while being drawn into the locking ring 710 only for a short time in the range that does not interfere with the safe operation.

이와같이 구성되는 본 발명의 자동차의 주행안전성 유지방법은 자동차의 주행속도가 핸들쏠림 및 롤링 영향을 받을 수 있는 기준속도 이상인 경우, 감지센서(100)가 이를 감지하여 자동차의 프론트범퍼 좌우 양측에 각각 설치되어 있는 피 토관(200)을 통해 자동차의 전면 좌우양측과 자동차의 좌우 양측측면방향의 풍압을 측정하게되고, 상기 상기 피토관(200)을 통해 측정된 풍압은 제어부(300)로 전달되어 지게되며, 상기 제어부(300)는 자동차의 좌측풍압과 우측풍압 및 전방좌우측의 풍압의 압력차를 비교하게 된다.In the driving safety maintenance method of the vehicle of the present invention configured as described above, when the driving speed of the vehicle is higher than a reference speed that may be affected by steering and rolling, the detection sensor 100 detects this and installs each of the front bumper left and right sides of the vehicle. Through the pitot pipe 200 is measured the wind pressure of the front left and right sides of the car and the left and right both sides of the car, the wind pressure measured through the pitot pipe 200 is transmitted to the control unit 300, The controller 300 compares the pressure difference between the left wind pressure, the right wind pressure, and the front left and right wind pressures of the vehicle.

한편, 상기 제어부(300)에서 비교된 자동차의 좌우 양측 및 전방좌우의 압력차가 핸들쏠림 및 롤링 발생 기준값 이상인 경우에는 핸들쏠림방지제어신호가 출력되어 전자스티어링컬럼록(400)의 록바(410)가 모터(미도시)의 구동력에 의해 외부로 인출되면서 상기 록바(410)가 록링(700)의 록링홀(710)에 삽입되면서 스티어링컬럼(600)을 록킹시켜 핸들쏠림현상이 발생하지 않도록 하게 된다.On the other hand, when the pressure difference between the left and right sides and the front left and right of the car compared by the control unit 300 is greater than the steering wheel rolling and rolling generation reference value, the steering wheel anti-steering control signal is output to lock bar 410 of the electronic steering column lock 400 The lock bar 410 is inserted into the lock ring hole 710 of the lock ring 700 while being drawn out to the outside by a driving force of a motor (not shown) to lock the steering column 600 so as not to cause handle pull phenomenon.

물론, 상기 록바(410)는 안전운행에 지장이 없는 범위의 짧은 시간동안만 록링홀(710)에 인입이 이루어지면서 스티어링컬럼(600)을 록킹시키게 된다.Of course, the lock bar 410 locks the steering column 600 while the lock bar 410 is pulled in only for a short time in a range that does not interfere with the safe operation.

이때, 상기 제어부(300)에서는 풍압이 높은 방향의 자동차 일측 댐핑포스가 일정시간동안 상승되어 롤링이 발생되지 않도록 전자제어현가장치(ECS)가 작동되는 것에 의해 롤링이 발생하지 않게 된다.In this case, the controller 300 does not cause rolling by operating the electronic control suspension device (ECS) so that the damping force of the vehicle in a high wind pressure direction is raised for a predetermined time so that rolling does not occur.

따라서 이러한 본 발명은 자동차를 주행 시 자동차의 전방좌우 양측 및 자동차의 좌우 양측에 풍압차가 발생하는 경우에도 순간적인 스티어일컬럼록이 이루어져 핸들쏠림현상이 발생하지 않게 됨은 물론, 자동차 좌우 양측에 발생되는 풍압차에 의해 서도 롤링현상이 일어나지 않게 됨으로서, 자동차를 주행시 안정성이 향상 되어지게 됨은 물론, 차실에 탑승한 승원의 승차감이 향상되어지도록 하는 등의 효과가 있는 매우 유용한 발명이다.Therefore, in the present invention, even when wind pressure difference occurs in the front left and right sides of the car and the left and right sides of the car while driving the vehicle, the steering wheel column is instantaneously generated, so that steering wheel steering does not occur, and is generated on both sides of the car. The rolling phenomenon does not occur even by the wind pressure difference, so that the stability of the vehicle while driving is improved and the riding comfort of the occupant in the vehicle is very useful.
