    The present invention relates to a device for controlling the operation of the air bag system (AIR BAG SYSTEM), and more particularly, the occupant in the passenger seat by detecting whether the occupant is in the passenger seat and whether the occupant is an infant or an adult Is to prevent the deployment of a passenger seat airbag in the event of a vehicle crash.
    As is well known, the airbag system instantly inflates the bag (BAG) with gas between the passenger and the steering wheel or the instrument panel in the event of a frontal charge, thereby avoiding the passenger's secondary injuries. In order to alleviate, as shown in FIG. 1, it consists of the sensor G sensor installed in the center, and the front G sensor provided in the front end part of the left and right front apron upper members, respectively, and the shock which detects the impact amount of a vehicle body, Acceleration detection sensors, airbag microphones to control the operation of the airbags, steering wheels with built-in inflator and airbags, and fault warning lamps indicating failure of the airbag system are installed on the vehicle body. When detected through the impact acceleration detection sensor (center G sensor, front G sensor) and input to the ECU, the air bag can be deployed according to the intensity of the impact. It is necessary to determine whether there is a need, and when the airbag needs to be deployed, send an electrical signal to the inflator to burn the gas generating agent to inflate the airbag.
    FIG. 2 is a view illustrating the deployment of the airbag, and as shown in the figure, protects the passenger's head chest to prevent secondary collision with the steering wheel or the windshield.
    However, the airbag system operating as described above has a problem in that, in the case of a child, the weight of the airbag system is designed to be mainly for adults.
    That is, as shown in the airbag deployment view of FIG. 2, there is a problem that the child's neck bone is broken or suffocated by the inflating force of the airbag.
    An object of the present invention is to solve the above-mentioned conventional problems, in particular, whether the occupant occupied in the passenger seat and whether the occupant is an infant or an adult if the occupant boarded, In the case of an infant, it is possible to provide a vehicle airbag system operation control device capable of preventing an injury due to an airbag by preventing deployment of a passenger seat airbag when a vehicle is charged.
    In order to achieve the above object, the vehicle airbag system operation control apparatus of the present invention includes a passenger detection unit for detecting the presence of a passenger and whether the occupant is an infant or an adult, a passenger seat airbag operated by a predetermined control signal, and The driver's seat airbag operated by the control signal of the driver, an alarm signal generator for generating an alarm signal for fastening the safety belt by a predetermined control signal, the signal output terminal of the occupant detection unit, the passenger seat airbag, the driver's airbag And, it is connected to each control signal input terminal of the alarm signal generator, first, if the occupant detection unit is determined that the occupant is not boarding, so that the passenger seat airbag is not deployed when the vehicle crash, second, it is determined that the child boarded In this case, it outputs an alarm signal to fasten the safety belt, Seat air bag not to deploy, and Third, if it is determined that the adult board is composed of a microcomputer, including an air bag which, deploy the air bag in a normal operation, characterized in that on the technical configuration.
    In addition, the occupant detection unit, the first switch means is installed in the passenger seat seat, the switch is switched when a passenger of a predetermined height or more, and the second switch is installed at the bottom of the passenger seat seat, the switch according to whether or not the passenger It is characterized in that it comprises a means.
    Such an airbag system operation control apparatus of the present invention detects whether a passenger rides through a second switching means installed at the bottom of the seat, and whether the occupant is a child or an adult through the first switching means installed at the seat neck. If the occupant is not occupied in the passenger seat, the passenger seat airbag will not operate when the vehicle is crashed. In the event of a vehicle crash, the passenger seat airbag is not operated, thereby preventing injuries caused by the airbag.
    Hereinafter, with reference to the accompanying drawings for an embodiment according to the technical idea of the present invention vehicle airbag system operation control device configured as described above in detail as follows.
    Example
    First, as shown in FIG. 4, when the second switching means switched by the occupant is installed under the passenger seat to be switched by the weight of the occupant, and also when the height of the occupant is abnormally predetermined on the seat neck. In order to detect the presence or absence of switching by the contact of the head, the first switching means is for detecting whether the occupant is an adult or a child.
    3, the signal output terminal of the occupant detection unit 10 is connected to the signal input terminal of the airbag micom 20, and the control signal input terminal of the passenger seat airbag 30 and the control of the driver's seat airbag 40 are performed. The signal input terminal is connected to the control signal output terminal of the airbag microphone 20, respectively, and the control signal input terminal of the alarm signal generator 50 is connected to the control signal input terminal of the airbag microphone 20 to constitute the present embodiment. .
    Here, the alarm signal generating unit 50 is made of a known sound generating circuit that is operated by a control signal applied from the air bag microphone 20 to generate a specific sound.
    Hereinafter, the operation of the present embodiment configured as described above will be described.
    First, when a key is inserted into an engine key cylinder and the engine is started, the airbag microcomputer 20 detects a signal for the presence or absence of a passenger applied by the passenger detecting unit 10 and a signal for distinguishing whether the passenger is an adult or a child. Done.
    That is, as shown in Figure 4, by detecting the switching state of the first switching means (SW1) and the second switching means (SW2) it is detected whether the occupant and whether the occupant is an adult or a child.
    For example, when the occupant is seated on the passenger seat, the second switching means SW2 is in contact with each other, and thus the second switching means input terminal of the airbag microphone 20 is connected through the second switching transistor Q2. HIGH VOLTAGE is applied to IN2). Then, the airbag microphone 20 is to recognize this as a signal that the occupant boarded.
    In addition, when the adult is seated in the passenger seat, the first switching means (SW1) is turned on by the head of the adult, thereby the airbag microphone (the first switching means input terminal of the two) through the first switching transistor (Q1). The high voltage is applied to IN1, and the airbag microphone 20 recognizes that the passenger is an adult.
    In the drawings, reference numerals R1 to R10 denote resistances, C1 and C2 denote noise canceling capacitors, and B + denotes a positive voltage of the battery, respectively.
    Accordingly, the presence or absence of the occupant and whether the occupant is an adult or a child can be detected, and the above object is achieved by operating the airbag according to the detected result.
    As described above, the vehicle airbag system operation control apparatus of the present invention, in particular, detects whether the passenger rides through the second switching means installed on the bottom of the seat, the occupant through the first switching means installed on the seat neck It is determined whether the child is a child or an adult.If the passenger is not in the passenger seat, the passenger's seat airbag is not activated when the vehicle is filled.In the case of a child, the safety belt is generated by generating an alarm signal to fasten the safety belt. After wearing it must be worn, the passenger seat airbag does not operate when the vehicle crashes, thereby preventing the injury caused by the airbag.
