조수석 에어백 제어장치Passenger Seat Airbag Control

본 고안은 차량의 에어백 제어장치에 관한 것으로서, 특히 조수 석에 승차하는 승객의 유무에 따라 조수석 에어백의 작동여부를 제어하는 조수석 에어백 제어장치에 관한 것이다.The present invention relates to a vehicle airbag control device, and more particularly to a passenger seat airbag control device for controlling the operation of the passenger seat airbag according to the presence or absence of passengers in the passenger seat.

일반적으로 운전석 및 조수석에 위치한 에어백은 차량충돌시 승객의 승차 유무에 관계없이 동시에 작동을 하게 되는 것으로, 이때 조수석에 승객이 승차하지 않은 상태에서 차량충돌이 일어나면 조수석의 에어백이 불필요하게 작동되므로서, 작동후의 에어백 관리에 있어 많은 비용이 소요되는 문제점이 있었다.In general, the airbags located in the driver's seat and the passenger seat are operated at the same time regardless of whether or not the passenger is riding in a vehicle crash. At this time, if a vehicle collision occurs without a passenger riding in the passenger seat, the passenger's airbag is operated unnecessarily, There was a problem in that the airbag management after the operation is expensive.

따라서, 본 고안은 이와같은 문제점을 해결하기 위해 조수석에 승차하는 승객의 유무를 감지하여 조수석의 에어백을 제어하는 시스템을 구성시키므로서, 차량 충돌시 조수석의 승객 유무에 따라 에어백의 작동여부를 판단하여 에어백의 불필요한 작동을 방지하고, 이에따라 작동후의 에어백 관리에 드는 비용을 절감시키고자 하는데 그 목적이 있다.Therefore, the present invention configures a system for controlling the passenger's airbag by detecting the presence of a passenger riding in the passenger seat in order to solve such a problem, and determines whether the airbag is operated in accordance with the passenger's passenger in the vehicle crash. The purpose of this is to prevent unnecessary operation of the airbag and thus to reduce the cost of airbag management after operation.

상기 목적 달성을 위한 본 고안 조수석 에어백 제어장치는 도면 제 1 도에 도시된 바와 같이, 차량의 충돌상태를 감지하도록 차량의 앞쪽 좌우사이드 멤버 하단에 설치된 좌우 임펙트 센서(1)(2)와, 차량의 윈드 쉴트 클래스에 장착되면서 적외선 또는 초음파를 이용하여 차량의 조수석에 승차되는 승객의 승차유무를 감지하는 신호발생 센서(3)와, 좌우 임펙트 센서(1)(2)에 의해 감지된 차량의 충돌상태에 따라 스티어링 휠내에 장착된 운전석 에어백을 작동시키는 제어신호를 출력시키면서 상기 신호발생 센서(3)에 의해 감지된 승객이 승차유무에 따라 글러브 박스에 장착된 조수석 에어백의 작동을 제어하는 전자제어 유니트(ECU)(4)와, 스티어링 휠내에 장착되어 상기 ECU(4)의 제어에 따라 운전석 및 조수석의 에어백을 작동시키도록 가스발생제를 연소시키는 운전석 인플레이터(5) 및 조수석 인플레이터(6)로 구성된 것이다.The present invention passenger seat airbag control device for achieving the above object, as shown in Figure 1, the left and right impact sensor (1) (2) and installed on the bottom of the front left and right side members of the vehicle to detect the collision state of the vehicle, The vehicle is detected by a signal generating sensor (3) and a left and right impact sensor (1) (2), which are mounted on the wind shield class and detect the presence or absence of a passenger riding in the passenger seat of the vehicle using infrared or ultrasonic waves. Electronic control unit for controlling the operation of the passenger seat airbag mounted on the glove box according to the presence or absence of passengers detected by the signal generating sensor (3) while outputting a control signal for operating the driver seat airbag mounted in the steering wheel according to the state (ECU) 4 and a gas generator which is mounted in the steering wheel to operate the airbags of the driver's seat and the passenger seat under the control of the ECU 4. Is configured to seat the inflator 5 and the inflator passenger seat (6).

이와 같이 구성된 본 고안 조수석 에어백 제어장치의 동작에 대하여 설명하면 다음과 같다.Referring to the operation of the present invention passenger seat airbag control device configured as described above are as follows.

먼저, 차량의 조수석에 승객이 승차되지 않은 상태에서 운전자가 차량을 운행시키는 도중에 충돌사고가 발생되면, 차량의 앞쪽 좌우사이드 멤버 하단에 설치된 좌우 임펙트 센서(1)(2)에서는 차량의 충돌상태를 감지한 후, 상기 감지된 차량의 상태를 ECU(4)에 출력시킨다.First, if a crash occurs while the driver is driving the vehicle while the passenger is not occupied in the passenger seat of the vehicle, the left and right impact sensors (1) and (2) installed at the lower left and right side members of the front of the vehicle detect the collision state of the vehicle. After sensing, the state of the detected vehicle is output to the ECU 4.

그리고, 상기 차량의 윈드 쉴트 클래스에 장착되면서 적외선 또는 초음파를 이용한 신호발생 센서(3)에서는 현재 차량의 조수석에 승객이 승차되어 있지 않음을 감지한 후, 이를 상기 ECU(4)에 출력시키게 된다.In addition, the signal generation sensor 3 using infrared or ultrasonic wave while being mounted on the wind shield class of the vehicle detects that the passenger is not currently occupied in the passenger seat of the vehicle, and then outputs it to the ECU 4.

이때, 상기 ECU(4)에서는 좌우 임펙트 센서(1)(2) 및 신호발생 센서(3)에 의해 감지된 차량의 충돌상태 및 조수석의 승객없음을 인식 하면서 운전석 및 조수석 인플레이터(5)(6)를 제어하게 되는 것이다.At this time, the ECU 4 recognizes the collision state of the vehicle detected by the left and right impact sensors 1 and 2 and the signal generating sensor 3 and the passenger absence of the passenger seat while the driver's seat and the passenger seat inflator 5 and 6 are recognized. Will be controlled.

즉, 상기 ECU(4)의 제어에 따라 운전석 인플레이터(5)에서는 가스 발생제를 연소시키고, 상기 운전석 인플레이터(5)에 의해 연소된 가스발생제에 따라 스티어링 휠내에 장착된 운전석 에어백이 팽창되므로서, 차량충돌시 운전석의 운전자를 보호하게 되며, 조수석에는 승객이 없으므로 상기 ECU(4)의 제어에 따라 조수석 인플레이터(6)는 동작을 하지 않게 되므로서, 글러브 박스에 장착된 조수석 에어백은 작동되지 않는 것이다.That is, the driver's seat inflator 5 burns the gas generator under the control of the ECU 4, and the driver's seat airbag mounted in the steering wheel is inflated according to the gas generator burned by the driver's seat inflator 5. The driver's seat protects the driver's seat during a vehicle crash. Since there is no passenger in the passenger seat, the passenger seat inflator 6 does not operate under the control of the ECU. Thus, the passenger seat airbag mounted on the glove box does not operate. will be.

한편, 차량의 조수석에 승객이 승차된 상태에서 운전자가 차량을 운행 시키는 도중에 충돌사고가 발생되면, 차량의 앞쪽 좌우사이드 멤버 하단에 설치된 좌우 임펙트 센서(1)(2)에서는 차량의 충돌상태를 감지한 후, 상기 감지된 차량의 상태를 ECU(4)에 출력시킨다.On the other hand, if a crash occurs while the driver is driving the vehicle while the passenger is in the passenger seat of the vehicle, the left and right impact sensors (1) and (2) installed on the lower left and right side members of the vehicle detect the collision state of the vehicle. After that, the state of the detected vehicle is output to the ECU 4.

그리고, 상기 차량의 윈트 쉴트 클래스에 장착되면서 적외선 또는 초음파를 이용한 신호발생 센서(3)에서는 현재 차량의 조수석에 승객이 승차되어 있음을 감지한 후, 이를 상기 ECU(4)에 출력시키게 된다.In addition, the signal generation sensor 3 using infrared rays or ultrasonic waves while being mounted on the windshield class of the vehicle detects that the passenger is currently occupied in the passenger seat of the vehicle and outputs it to the ECU 4.

이때, 상기 ECU(4)에서는 좌우 임펙트 센서(1)(2) 및 신호발생 센서(3) 에 의해 감지된 차량의 충돌상태 및 조수석의 승객있음을 인식하면서 운전석 및 조수석의 인플레이터(5)(6)를 제어하게 된다.At this time, the ECU 4 recognizes the collision state of the vehicle and the passenger seat of the passenger seat detected by the left and right impact sensors 1 and 2 and the signal generating sensor 3, and the inflators 5 and 6 of the driver's seat and the passenger seat. Will be controlled.

즉, 상기 ECU(4)의 제어에 따라 운전석 및 조수석 인플레이터(5)(6) 에서는 가스발생제를 연소시키고, 상기 인플레이터(5)(6)에서 연소된 가스발생제에 따라 스티어링 휠내에 장착된 운전석 에어백 및 글러브 박스에 장착된 조수석 에어백이 팽창되므로서, 차량의 충돌시 운전석의 운전자 및 조수석의 승객을 동시에 보호하게 되는 것이다.That is, under the control of the ECU 4, the driver's seat and the passenger seat inflator 5 and 6 burn the gas generator, and the gas generator burned in the inflator 5 and 6 is mounted in the steering wheel. As the passenger seat airbag mounted on the driver's seat airbag and the glove box is inflated, the driver's seat and the passenger's passenger at the same time are protected at the time of the vehicle crash.

이상에서 설명한 바와 같이 본 고안은 조수석에 승차하는 승객의 유무를 감지하여 조수석의 에어백을 제어하는 시스템을 구성시키므로서, 차량 충돌시 조수석의 승객 유무에 따라 에어백의 작동여부를 판단하여 에어백의 불필요한 작동을 방지하고, 이에 따라 작동후의 에어백 관리에 드는 비용을 절감시키는 효과가 있는 것이다.As described above, the present invention configures a system for controlling the passenger's airbag by detecting the presence of a passenger riding in the passenger seat, thereby determining whether the airbag is operated in accordance with the passenger's presence or absence of the passenger's seat when the vehicle crashes. And thus reduce the cost of airbag management after operation.
