도 2 에 보여지는 바와같이, 차량의 측면에 강한 충격이 가해졌을 경우 측면충돌판정기(100)의 제 1 마이컴(101)은 충돌을 중앙에어백제어장치(200)로 전달하기 위해 트랜지스터(Q2)의 베이스단자와 전압강하부(103)에 신호를 인가하게 된다. 상기 제 1 마이컴(101)으로부터 신호를 인가받은 전압강하부(103)와 트랜지스터(Q2)가 턴온된다.As shown in FIG. 2, when a strong impact is applied to the side of the vehicle, the first microcomputer 101 of the side collision determiner 100 transmits the collision to the central airbag control device 200. The signal is applied to the base terminal and the voltage drop section 103 of the. The voltage drop unit 103 and the transistor Q2 that receive a signal from the first microcomputer 101 are turned on.
이때, 상기 제 1 마이컴(101)은 DC/DC변화기(105)에서 변화된 전압으로 구동되며 배터리로부터 전원이 인가되지 않 을때는 보조전원(107)으로부터 전원을 인가받아 구동되는데 이는 차량의 시동이 오프되어 전장용품에 전원이 인가되지 않을 때 소정시간 동안만 구동된다.In this case, the first microcomputer 101 is driven by the voltage changed by the DC / DC converter 105 and is driven by receiving power from the auxiliary power source 107 when power is not applied from the battery. It is driven only for a predetermined time when power is not applied to the electrical appliance.
상기에서와 같이, 차량의 측면에 충격이 가해지면 이는 중앙제어장치(200)의 제 2 마이컴(202)으로 인가되는데, 먼저 제 1 마이컴(101)의 신호를 인가받아 트랜지스터(Q2)가 온되면 통신라인을 통해 제 2 마이컴(202)으로 신호가 인가되는데 상기 제 1 마이컴(101)으로부터 신호를 인가받은 중앙제어장치(200)의 신호전달부(208)는 배터리로부터 인가되는 전류를 전압으로 변환하여 제 2 마이컴(202)에 하이신호를 인가하게 된다.As described above, when an impact is applied to the side of the vehicle, it is applied to the second microcomputer 202 of the central control unit 200. First, when the transistor Q2 is turned on by receiving the signal of the first microcomputer 101. A signal is applied to the second microcomputer 202 through a communication line, and the signal transmission unit 208 of the central controller 200 that receives the signal from the first microcomputer 101 converts the current applied from the battery into a voltage. The high signal is applied to the second microcomputer 202.
통신라인을 통한 통신을 좀더 자세히 살펴보면, 4비트로 구성되어 총 16=24의 명령어 전달이 가능한데 명령어가 나 간후 바로 컴플리먼트(COMPLEMENT)를 취한 값을 내보내 받는 곳에서 확인하게 해준다.If you look at the communication through the communication line in more detail, it is composed of 4 bits and 16 = 24 instructions can be delivered. After completion of the instruction, you can check the complement value at the receiving point.
통신은 펄스의 길이를 조정하여 전달하는데 아래 파형에서 보여지는 것과 같이, 로직이 '0'이면 로직간격을 1㎳, 인터발길이를 3㎳로 하고, 로직이 '1'이면 로직 길이를 2㎳, 스톱비트를 0으로 한다.Communication adjusts the length of the pulse and transmits it. As shown in the waveform below, if the logic is '0', the logic interval is 1㎳ and the interval length is 3㎳. If the logic is '1', the logic length is 2㎳, Set the stop bit to zero.
(파형)(Waveform)
또한, 차량의 측면에 충격이 가해지면 측면충돌판정기(100)의 제 1 마이컴(101)은 전압강하부(103)로 신호를 인가하게 되며, 상기 제 1 마이컴(101)으로부터 신호를 인가받은 전압강하부(103)의 트랜지스터(Q2)가 온되어 DC/DC변환기(105)로 전원라인을 통해 인가되는 배터리의 소정전압이 그라운드로 흐르게되어 전압강하가 일어나게된다.In addition, when an impact is applied to the side of the vehicle, the first microcomputer 101 of the side collision determiner 100 applies a signal to the voltage drop unit 103 and receives a signal from the first microcomputer 101. The transistor Q2 of the voltage drop unit 103 is turned on so that a predetermined voltage of the battery applied to the DC / DC converter 105 through the power line flows to the ground, causing a voltage drop.
상기 전압강하부(103)에서 전압강하가 일어나게되면 중앙에어백제어장치(200)의 전압증폭비교부(206)에서는 배터리로부터 인가되는 전압을 증폭하여 기준전압과 비교하고 증폭된 전압이 기준전압보다 높으면 제 2 마이컴(202)으로 하이신호를 인가하게 된다.When a voltage drop occurs in the voltage drop unit 103, the voltage amplification comparison unit 206 of the central airbag control device 200 amplifies a voltage applied from a battery, compares it with a reference voltage, and when the amplified voltage is higher than the reference voltage. The high signal is applied to the second microcomputer 202.
상기 전압증폭비교부(206)와 신호전달부(208)로부터 하이신호를 인가받은 제 2 마이컴(202)은 두신호를 비교하여 두 신호가 동일하면 측면에어백 점화장치(도시되지 않음)에 점화신호를 인가하게 된다.The second microcomputer 202, which receives the high signal from the voltage amplifier 206 and the signal transfer unit 208, compares the two signals, and if the two signals are the same, the ignition signal to the side airbag ignition device (not shown). Will be applied.
한편, 차량측면에 강한 충격으로 인해 통신라인이 파손되면 제 2 마이컴(202)은 전원라인을 통해 인가된 신호만으로 측면에어백 전개를 제어하게됨으로 통신라인이 파손되더라도 측면에어백을 빠르게 전개시킬수 있다.On the other hand, if the communication line is broken due to a strong impact on the vehicle side, the second microcomputer 202 controls the side airbag deployment only by the signal applied through the power line, so that the side airbag can be rapidly deployed even if the communication line is broken.
이하 측면 에어백과의 통신방법을 도 3 을 참조하여 설명하면, 측면충돌판정기와 중앙제어장치간의 통신라인이 접속되었나를 비교판단하는 제 1 단계(S1)와; 상기 제 1 단계(S1)의 비교판단 결과 통신라인이 접속되어있지 않을 경우 고장기록 및 경고등을 통해 사용자에게 알리는 제 2 단계(S2)와; 상기 제 1 단계(S1)의 비교판단 결과 통신라인이 접속되어 있을 경우 측면충돌판정기와 중앙제어장치간의 전원라인이 접속되었나를 비교판단하는 제 3 단계(S3)와; 상기 제 3 단계(S3)의 비교판단 결과 전원라인이 접속되어 있지 않을경우 상기 제 2 단계(S2)를 수행하고, 상기 제 3 단계(S3)의 비교판단 결과 전원라인이 접속되어 있을경우 측면충돌판정기로부터 통신라인과 전원라인을 통해 인가된 명령어가 일치하는가를 비교판단하는 제 4 단계(S4)와; 상기 제 4 단계(S4)의 비교판단 결과 명령어가 일치하지 않을경우 상기 제 2 단계(S2)를 수행하고, 상기 제 4 단계(S4)의 비교판단 결과 명령어가 일치할 경우 명령어를 해독하고 명령어를 실행하는 제 5 단계(S5)로 동작된다.Hereinafter, a method of communicating with the side airbag will be described with reference to FIG. 3, and a first step S1 of comparing and determining whether a communication line between the side collision determiner and the central controller is connected; A second step (S2) of notifying the user through a failure record and a warning light when the communication line is not connected as a result of the comparison determination in the first step (S1); A third step (S3) of comparing and determining whether a power supply line between the side collision determiner and the central control device is connected when the communication line is connected as a result of the comparison determination in the first step (S1); If the power line is not connected as a result of the comparison of the third step S3, the second step S2 is performed. If the power line is connected as a result of the comparison, the side collision is performed. A fourth step (S4) of comparing and determining whether a command applied from the determiner through the communication line and the power line is identical; If the comparison determination result command of the fourth step S4 does not match, perform the second step S2. If the comparison determination result command of the fourth step S4 matches, the command is decoded and the instruction is executed. The fifth step S5 is executed.
