  FIG. 1 to FIG. 3 show an embodiment of the present invention. FIG. 1 is a schematic explanatory diagram of a vehicle interior, FIG. 2 is a schematic block diagram of an airbag control device, and FIG. 3 is a control operation of the airbag control device. It is a flowchart which shows.

  The airbag control device 1 controls an airbag device 2 installed in front of a passenger seat of an automobile vehicle. As shown in FIG. 1, the airbag device 2 is installed on the back side of the instrument panel 4 located in front of the vehicle seat. The instrument panel 4 is formed with an airbag cover 5 that opens when the airbag is deployed. That is, when the airbag is rapidly deployed on the back side of the instrument panel 4, the airbag cover 5 of the instrument panel 4 is broken and separated from the panel body due to the impact during deployment.

  The airbag control device 1 includes a control unit 10 that is electrically connected to the airbag device 2 and an object detection sensor 11 that is connected to the control unit 10 and detects an object in the vehicle interior. Note that the object detection sensor 11 may detect an object using any one of infrared, laser, and ultrasonic waves, or may detect an object using an image such as a camera. The object detection sensor 11 is installed so as to detect an object in the automatic inhibition region 12 adjacent to the airbag cover 5 shown in FIG. This automatic inhibition region 12 is set in the airbag deployment region ES according to the type of vehicle, the specifications of the vehicle seat and the airbag device 2, and the like.

  The control unit 10 includes a CPU 10a as a calculation unit, and a ROM 10b and a RAM 10c as storage units, and controls the airbag device 2 based on a signal transmitted from an acceleration sensor 13 installed at the front portion of the vehicle. To do. When ROM 10b determines that the vehicle has collided based on a signal transmitted from acceleration sensor 13, an airbag deployment control program 21 is stored which causes the inflator of airbag device 2 to generate gas and deploy the airbag. Yes. That is, in this embodiment, the control unit 10 constitutes an airbag deployment control means.

  The ROM 10b stores a dynamic detection program 22 for continuously detecting the presence or absence of an object in the automatic suppression area 12 by the object detection sensor 11 when it is determined that the vehicle has collided. That is, in the present embodiment, the control unit 10 serves as a first detection unit. Here, “continuous” means continuous with respect to time, and includes a case where the detection operation by the object detection sensor 11 is performed at a relatively short time interval of, for example, about 0.001 seconds, and at a constant time, for example. It is. Thereby, it is possible to accurately detect an object that dynamically enters the automatic inhibition region 12 at the time of a vehicle collision. Further, the ROM 10 b stores a dynamic prohibition program 23 that prohibits the airbag deployment operation by the airbag deployment control program 21 when an object is detected by the dynamic detection program 22. That is, in the present embodiment, the control unit 10 constitutes a dynamic detection prohibiting unit.

  The ROM 10b also stores a static detection program 24 that periodically detects the presence or absence of an object in the automatic suppression area 12 by the object detection sensor 11. That is, in the present embodiment, the control unit 10 serves as the second detection unit, and the dynamic detection program 22 and the static detection program 24 share the object detection sensor 11. In the present embodiment, the static detection program 24 performs the detection operation by the object detection sensor 11 at a predetermined time interval such as 10 seconds, and also when the seat belt buckle switch 14 is switched ON / OFF, This is performed when the weight of the vehicle seat is detected by the weight sensor 15 and also when the position of the vehicle seat is changed by the seat position detection sensor 16 for moving the seat back and forth. Thereby, the object located in the automatic suppression area | region 12 can be detected before a vehicle collision.

  Further, in the ROM 10b, when an object is detected by the static detection program 24, a static prohibition program 25 for prohibiting the airbag deployment operation by the airbag deployment control program 21 and an airbag A deployment prohibition notification program 26 for notifying an occupant using an indicator 17 installed on a meter panel, an instrument panel or the like is stored. That is, in this embodiment, the control unit 10 serves as static detection prohibiting means and deployment prohibition notifying means. In the present embodiment, the buckle switch 14, the weight sensor 15, the seat position detection sensor 16, and the indicator 17 are connected to the control unit 10.

  Further, the airbag deployment control program 21 changes the deployment state of the airbag based on the state of the occupant detected by the buckle switch 14 as the occupant detection means, the weight sensor 15 and the seat position detection sensor 16. ing.

  The airbag deployment control program 21 determines that the occupant is not wearing the seat belt and does not change the airbag deployment state when the buckle switch 14 for detecting the seat belt buckle fixed state is in the OFF state. . When the buckle switch 14 is in the ON state, the airbag is changed to a small deployment state.

  The airbag deployment control program 21 determines whether an adult is seated on the vehicle seat or a child is seated based on the weight detected by the weight sensor 15 that detects the weight of the occupant seated on the seat. If it is determined that a child is seated on the vehicle seat, the airbag is changed to a state where the impact applied to the occupant is small. Further, when it is determined that an adult is seated on the vehicle seat, the deployed state of the airbag is not changed. Note that a function for determining that the vehicle seat is in an empty seat state may be added so that the airbag deployment operation is prohibited when it is determined that the vehicle seat is in an empty seat state.

  Further, the airbag deployment control program 21 determines the front / rear state of the vehicle seat based on the stop state of the seat position detection sensor 16, and if it is determined that the vehicle seat is in front of the predetermined position, It is determined that the distance is small, and the deployment state of the airbag is changed to one with a small impact applied to the passenger. That is, in the present embodiment, the seat position detection sensor 16 detects the front and rear positions of the seat on which the occupant is seated. When it is determined that the vehicle seat is behind the predetermined position, it is determined that the occupant's physique is large, and the airbag deployment state is not changed. Of course, the front and rear positions of the vehicle seat may be identified in multiple stages, and the deployment state of the airbag may be controlled in multiple stages.

  Operation | movement of the control part 10 of the airbag control apparatus 1 comprised as mentioned above is demonstrated with reference to the flowchart shown in FIG. The first flag X relates to the airbag deployment state, and the second flag Y relates to detection of an object before a vehicle collision in the automatic suppression region.

  First, when the ignition switch of the vehicle is turned on (step S1), as described above, the occupant state is detected using the buckle switch 14, the weight sensor 15, and the seat position detection sensor 16, and the airbag is deployed. It is determined whether or not the current state is to be changed (step S2). If it is determined that the airbag deployment state is to be changed, the flag X is set to 1 (step S3), and if it is determined that the airbag deployment state is not changed, the flag X is set to 0 (step S3). Step S4).

  After step S3 and step S4, it is determined based on the static detection program 24 whether or not an object is present in the automatic suppression area 12 (step S5). If an object is present, the flag Y is set to 1 (step S5). S6), the indicator 17 is turned on (step S7). If it is determined in step S5 that no object exists in the automatic inhibition area 12, the flag Y is set to 0 (step S8).

  After step S7 and step S8, it is determined whether or not the vehicle has collided (step S9). If it is determined that the vehicle has not collided, the process proceeds to step S2, and the airbag deployment state is continuously changed. Monitor whether or not. If it is determined in step S9 that the vehicle has collided, it is determined whether or not the flag Y is 1 (step S10). If the flag Y is 1, the airbag deployment operation is prohibited (step S10). S11).

  If the flag Y is 0 in step S10, it is determined whether or not an object has entered the automatic inhibition area 12 based on the dynamic detection program 22 (step S12), and the object is detected in the automatic inhibition area 12. If it does, it will progress to step S11 and will prohibit the deployment operation | movement of an airbag.

  If no object is detected in the automatic inhibition area 12 in step S12, it is determined whether or not the flag X is 1 (step S13). At this time, if the flag X is 1, the airbag is deployed so that the impact applied to the occupant is reduced (step S14). When the flag X is 0, the airbag is deployed in a normal state (step S15).

  As described above, according to the airbag control device 1 of the present embodiment, when the collision of the vehicle is detected and the presence of the object in the automatic suppression area 12 is detected by the operation based on the dynamic detection program 22, the dynamic control is performed. The prohibition program 23 prohibits the airbag deployment operation. Thereby, when a passenger | crew leaves | separates from a vehicle seat and approaches the airbag apparatus 2 side at the time of a vehicle collision, a passenger | crew can avoid the impact by airbag deployment.

  In addition, even if the static detection program 24 detects the presence of an object in the automatic inhibition area 12 before the vehicle collision, the static deployment program 25 prohibits the airbag deployment operation of the airbag deployment control program 21. Thereby, even when there is a high probability that an object exists in the automatic inhibition area 12 before the vehicle collision and an object exists in the automatic inhibition area 12 even during the vehicle collision, the deployment operation of the airbag deployment control program 12 is prohibited. It is possible to further improve the safety of passengers.

  Further, since the dynamic prohibition program 23 determines the presence or absence of an object in a state where the vehicle actually collides, it is necessary to continuously monitor the automatic inhibition region 12 by the object detection sensor 11, which is relatively precise. Although control is required, since the static prohibition program 25 detects the object in advance and prohibits the airbag deployment operation, even if the automatic suppression area 12 is regularly monitored as in this embodiment, The operation of the airbag deployment control program 21 can be accurately prohibited at the time of a collision. Therefore, the control of the static prohibition program 25 does not increase the manufacturing cost, and the safety can be effectively improved within the limited manufacturing cost.

  In particular, in the airbag control device 1 of the present embodiment, by sharing the object detection sensor 11 that detects an object in the automatic inhibition region 12, it is possible to promote the sharing of parts and reduce the manufacturing cost. it can. That is, as in the present embodiment, in the operation based on the static detection program 24, detection by the object detection sensor 11 may be performed periodically during normal operation. In the operation based on the dynamic detection program 22, vehicle collision Sometimes the detection by the object detection sensor 11 may be performed continuously.

  Further, according to the airbag control device 1 of the present embodiment, since the airbag is deployed based on the state of the occupant detected before deployment of the airbag, the airbag is deployed so as to be suitable for the state of the occupant. The injury value of the occupant can be reduced, and the safety of the occupant can be further improved.

In the present embodiment, the seat belt buckle switch 14 can be used to determine the occupant's seat belt wearing state and change the airbag deployment state.
Further, by detecting the weight of the occupant seated on the vehicle seat using the weight sensor 15, it is possible to determine whether the occupant is an adult or a child and change the airbag deployment state. As described above, it may be determined whether the occupant is in an empty seat state.
Further, the airbag deployment state can be changed by determining the occupant's physique based on the front and rear positions of the vehicle seat on which the occupant is seated using the seat position detection sensor 16.

  Further, according to the airbag control device 1 of the present embodiment, the presence of an object in the automatic suppression area 12 is notified by the indicator 17, so that the occupant recognizes that the operation of the airbag is prohibited. can do. Therefore, the occupant can move the object present in the automatic restraining region 12 to a state in which the airbag is accurately operated, which is extremely advantageous in practical use.

  In addition, in the said embodiment, although what controlled the airbag apparatus 2 distribute | arranged ahead of a passenger seat was shown, you may control the airbag apparatus distribute | arranged ahead of a driver's seat. In this case, the airbag device is installed not on the instrument panel but on the steering, and the automatic inhibition region is set so as to be adjacent to the airbag cover of the steering. In the case of a driver's seat, it is useful to determine whether the occupant's physique is large or small, but it is possible to determine whether the occupant is an adult, a child, or an empty seat. Is no longer necessary.

Moreover, in the said embodiment, although what showed the state of a passenger | crew by the buckle switch 14, the weight sensor 15, and the seat position detection sensor 16 was shown, the deployment state of an airbag was shown, but it is related with the deployment state of an airbag. The function may be omitted. That is, as shown in FIG. 4, step S2, step S3, step S4, step S13, and step S14 of the embodiment may be omitted. This can also improve the safety of the passenger.
If it is not necessary for an adult to suppress the airbag, the airbag can be deployed without passing through steps S5 and S12 when the passenger on the seat is identified as an adult in step S2. Thus, the reliability of the system can be improved.
Furthermore, even if the function relating to the static prohibition program 25 in the above embodiment is omitted, the safety of the passenger can be improved.

  In the above embodiment, the object detection sensor 11 is shared by the dynamic detection program 22 and the static detection program 24. However, it goes without saying that the sensors may be installed separately and independently. .

  Moreover, in the said embodiment, although what showed the indicator 17 that the deployment operation | movement of an airbag is prohibited by the static prohibition program 25 was shown, the object in the automatic suppression area | region 12 by the static detection program 24 was shown. You may make it alert | report by the indicator 17 that is detected. In this case, the control unit 10 serves as an object detection notification unit and is notified of the presence of the object in the automatic suppression area 12, so that the occupant recognizes that the airbag is being inhibited from being deployed by the object. be able to. Therefore, the occupant can move the object present in the automatic restraining region 12 to a state in which the airbag is accurately operated, which is extremely advantageous in practical use.

  Moreover, in the said embodiment, although what changed the deployment state of an airbag based on the weight detected by the weight sensor 15 which detects the weight of the passenger | crew seated on a sheet | seat was shown, for example, the seat of the passenger | crew who seated A load distribution sensor for detecting the load distribution in the vehicle may be provided, and the airbag deployment state may be changed based on the load distribution detected by the sensor. In this case, by detecting the load distribution on the seat, for example, it is possible to determine the occupant's physique and the like and change the airbag deployment state.

  Moreover, in the said embodiment, although the example which applied this invention to the airbag developed on a passenger | crew front side was shown, this invention is applied to other airbags, such as a curtain airbag, a side airbag, etc., for example.
