Collision position detection control device for car airbag collision detection sensor

摘要

According to the present invention, since the collision detection sensor and the SRS unit are separately provided in the airbag system, wiring is complicated, and a sensor for detecting a collision state from the front and a sensor for detecting a side collision must be provided separately. It is made to solve the disadvantage that the structure is elevated and the structure is complicated, a plurality of collision detection sensors for detecting the impact of the collision in the SRS unit for controlling the operating state of the airbag of the car, each predetermined angle with respect to the scene It provides a collision detection position control device of the airbag collision detection sensor for automobiles to simplify the structure of the system by being installed with the system, and also to detect the frontal collision and the side collision applied from various angles.;Accordingly, the present invention provides a predetermined angle with respect to the front surface within the SRS unit to detect the impact state caused by the frontal collision applied to the vehicle and the side impact applied at various angles. , ') A plurality of collision detection sensors 10A and 10B installed at an angle, and charge amplifiers 30A and 30B for preamplifying the detection signals from the collision detection sensors 10A and 10B, respectively, and the preamplification. Amplification units 40A and 40B for signal amplifying the detected detection signals, signal comparison units 50A and 50B for comparing the level of the voltage according to the amplified detection signal with a predetermined reference voltage, respectively, Signal detection unit 60 for detecting the voltage value and the voltage difference of the detection signal and the detection value according to the voltage value and the voltage difference from the signal detection unit 60 is recognized and outputs a control signal to a predetermined airbag driver side It is characterized by consisting of a microcomputer (70).
