Abstract

본 발명은 복수의 부탑승자 내의 어떤 부탑승자 보호장치로 부터 중요한 신호가 공급되었을 때에,주탑승자 보호장치는 다른 부탑승자 보호장치와의 통신을 중단하고 중요한 신호를 전송해온 부탑승자 보호장치하고만 통신을 하도록 한다.According to the present invention, when an important signal is supplied from a certain sub-rider protection device in a plurality of secondary passengers, the main passenger protection device stops communication with another secondary passenger protection device and communicates only with the secondary passenger protection device which has transmitted an important signal. Do it.

차량의 일측면(一側面)측에서의 충돌에 따른 가속도를 검출하는 복수의 좌우방향 가속도센서로부터의 가속도 신호에 의거하여 차량의 측방으로부터의 충돌크기를 판단하는 복수의 부신호처리회로와,그 복수의 부신호 처리회로 각각에 설치되어짐과 동시에 각각의 신호처리회로에서 처리된 판단신호를 요구신호에 응하여 통신라인에 출력하는 복수의 통신회로와,복수의 통신회로 각각에 요구신호와 출력함으로써 그것에 대응하는 부신호처리호로로부터 감시되어야 하는 신호를 입력했을때,그 신호를 출력한 부신호처리회로에 대해서만 요구신호로 출력하고 다른쪽의 부신호처리회로에 대해서는 요구신호를 출력하지 않는 주신호 처리회로를 갖추었다.A plurality of sub-signal processing circuits for determining the magnitude of the collision from the side of the vehicle on the basis of the acceleration signals from the plurality of left and right acceleration sensors for detecting the acceleration according to the collision on one side of the vehicle, A plurality of communication circuits provided in each of the sub-signal processing circuits and outputting a determination signal processed by each signal processing circuit to a communication line in response to a request signal, and outputting a request signal to each of a plurality of communication circuits. When a signal to be monitored from the sub-signal processing signal is inputted, the main signal processing circuit outputs the request signal only to the sub-signal processing circuit that outputs the signal and does not output the request signal to the other sub-signal processing circuit. Equipped.
