Description

Driver's passenger airbag operation control device according to passenger's seat

The present invention relates to a passenger seat airbag operation control apparatus for a vehicle according to the passenger seat, and more particularly to a device for controlling the passenger seat airbag operation when the passenger seated in the passenger seat.

In general, the steering wheel is mounted on an airbag for the driver's safety. The airbag swells like a balloon when a shock is applied to the vehicle, preventing the driver's upper body from hitting the steering wheel badly.

An airbag for this operation is mounted on a steering wheel and includes an inflator for injecting gas into the airbag. The inflator is connected to an electronic control unit (ECU), which controls the overall system of the vehicle, so that if a certain amount of impact is applied to the vehicle body, the electronic control unit detects this and operates the inflator.

That is, when a vehicle collides and a predetermined shock is applied, the electronic control unit operates the inflator to inject gas into the airbag. The airbag inflates rapidly with the gas imparted by the inflator, preventing the driver from hitting the steering wheel or windshield glass badly.

The airbag acting as described above is for the driver only, and in recent years, the vehicle equipped with the passenger seat airbag is rapidly increasing in order to ensure the safety of the occupant, especially the passenger seat occupant.

The passenger airbag is fitted to the instrument panel in front of the passenger seat, and is installed on a T-bar that supports the instrument panel laterally.

By the way, regardless of whether or not there is a passenger in the passenger seat, the passenger seat airbag is automatically operated when an impact is applied to the vehicle body unconditionally, but the passenger seat airbag is conventionally operated even without the passenger seat passenger.

Due to this, a problem arises that, once used, the airbag to be replaced with a new one is wasted.

Therefore, the present invention has been devised to solve the conventional problems, the passenger seat airbag is operated only when there is a passenger seat passenger, the passenger seat airbag operation of the vehicle according to the passenger seat board whether or not to waste expensive airbags The purpose is to provide a control device.

In order to achieve the above object, the present invention, as a device for controlling the operation of the passenger seat airbag to be mounted on the instrument panel in front of the passenger seat inflated like a balloon to protect the passengers when a predetermined or more impact is applied, A sensor attached to the passenger seat to detect whether a passenger is seated; And an electronic control unit for electronically controlling the operation of the inflator, which is the driving source of the passenger seat airbag, according to the signal sensed by the seating sensor.

According to the above-described configuration of the present invention, when the passenger seats in the passenger seat, the seating sensor detects this, and the electronic control unit enables the passenger airbag to operate. Will not.

EXAMPLE

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing a state in which a seating sensor, which is a main part of the present invention, is provided in a passenger seat, FIG. 2 is a block diagram illustrating an input / output process of an electronic control unit to which a signal of a seating sensor is input, and FIG. 3 is an operation of the present invention. It is a flow chart.

For reference, in the description of the configuration of the present embodiment, the same parts as in the prior art described at the beginning of the specification are omitted and repeated descriptions are mainly described in order to avoid duplication of description. use.

As shown in FIG. 1, the passenger seat 1 is provided with several seating sensors 2, which are connected to the connector 4. The connector 4 is connected to an electronic control unit that controls the operation of the airbag via a pigtail (pig tail) 5: and the electronic module 6 is provided on the side of the connector 4.

That is, as shown in Fig. 2, the electronic control unit 3 that controls the operation of the airbag is input with information on whether to start from the start sensor, the information on the acceleration situation is input from the acceleration sensor, and the seating sensor Information about whether or not there is a passenger in the passenger seat is inputted. According to this information, the electronic control unit 3 controls the airbag operation of the driver's seat and the passenger seat, that is, the operation of the inflator.

Hereinafter, the operation of the present embodiment configured as described above will be described in detail with reference to FIG. 3.

In step ST1, the start-up is started, and in step ST2, an acceleration condition, that is, a situation in which the vehicle speed is drastically reduced by the collision is detected, and this situation is input to the electronic control unit. Then, in step ST3, it is input to the electronic control unit whether or not there is a passenger in the passenger seat from the seating sensor.

If no passenger passenger is present, the driver's seat air million is activated in the event of a crash and the passenger seat airbag is not activated. On the contrary, if there is a passenger seat passenger, as in step ST4, the passenger seat airbag as well as the driver's seat are operated by the electronic control unit.

As described above, according to the present invention, the operation of the passenger seat airbag is controlled according to the passenger seat passenger, thereby preventing the expensive airbag from being wasted.

On the other hand, the present invention is not limited to the above-described specific preferred embodiments, anyone of ordinary skill in the art to which the present invention pertains without departing from the gist of the present invention claimed in the claims may be variously modified. will be.
