BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of deploying an airbag, and more particularly, to a method of deploying an airbag according to occupant type and attitude.

WCS (Weight Classification System) is a system that detects the weight of a passenger seated on a seat of a vehicle and determines whether the occupant is an infant less than six years old or an adult.

The WCS detects the occupant's weight by attaching a weight sensor, that is, a horizontal or vertical sensor, to the seat frame of the vehicle.

Such a WCS is used to regulate the inflation pressure of the airbag when the airbag is deployed. For example, when the occupant is an infant, the airbag is not deployed, or the airbag is inflated with a reduced inflation pressure. Thereby preventing the user from suffering damage.

The conventional airbag deployment system senses the collision of the vehicle, determines the type of the occupant through the WCS, and develops the airbag by varying the inflation pressure according to the occupant type.

However, the conventional airbag deployment system suffers from secondary damage such as injury without considering the posture of the occupant sitting on the vehicle seat. For example, when the occupant is leaning against the door of the vehicle, the side airbag is deployed There is a problem that the airbag further inflicts injury, or the occupant develops a high-pressure airbag in a state where the upper body is leaning forward, thereby inflicting damage on the cervical vertebrae and taking the lives of the occupant.

In order to fully understand the present invention, operational advantages of the present invention, and objects achieved by the practice of the present invention, reference should be made to the accompanying drawings and the accompanying drawings which illustrate preferred embodiments of the present invention.

Hereinafter, the present invention will be described in detail with reference to the preferred embodiments of the present invention with reference to the accompanying drawings. However, the present invention can be implemented in various different forms, and is not limited to the embodiments described. In order to clearly describe the present invention, parts that are not related to the description are omitted, and the same reference numerals in the drawings denote the same members.

Throughout the specification, when an element is referred to as " including " an element, it does not exclude other elements unless specifically stated to the contrary. The terms "part", "unit", "module", "block", and the like described in the specification mean units for processing at least one function or operation, And a combination of software.

Referring to FIG. 1, a method for deploying an airbag according to an occupant type and an attitude according to an embodiment of the present invention includes sensing a wearing of a seat belt (S101), determining an occupant type (S103), monitoring a load value change (S105) A value measurement step S107, a load value comparison step S109, a posture determination step S111, and an airbag deployment step S113.

The method for deploying an airbag according to an occupant type and an attitude according to an embodiment of the present invention first detects whether or not a passenger wearing a seat belt is wearing a seatbelt in a step S101 of sensing a seatbelt. Here, whether or not the seat belt is worn can be detected when the ignition switch of the vehicle is turned on. Accordingly, when the occupant wears the seat belt while the ignition switch of the vehicle is turned off, It can be judged.

Thereafter, the process proceeds to either step S103 or step S107 depending on whether the seat belt is worn.

When the occupant wears the seatbelt, the type of the occupant is determined using the load values according to the weight of the occupant in the occupant type determination step (S103). Here, the load values are measured from each side of the seat on which the occupant is seated, and the seat is equipped with, for example, a weight sensor for sensing the weight of the occupant.

A plurality of weight sensors can be mounted, and a first weight sensor and a second weight sensor are disposed at a predetermined distance from one side of a seat to which the backrest is coupled, and a second weight sensor is disposed at the other side of the seat opposite to the backrest, A third weight sensor, and a fourth weight sensor may be disposed.

The load values are measured by the respective weight sensors, and the load values may include a first load value, a second load value, a third load value, and a fourth load value sequentially corresponding to the respective weight sensors.

The occupant type is determined as adult if the total of the load values is higher than the predetermined first reference load value and the occupant type is judged to be adult if the sum of the load values is higher than the first reference load value and higher than the second reference load value. It can be judged to be vacant if it is lower than the second load value. Here, the first reference load value is set based on the average weight of the infants under six years of age, and the second reference load value can be set based on the weight of the car seat cover.

In the embodiment of the present invention, the occupant type is classified as vacant, infants less than 6 years old, and other adults. However, it is obvious that the type of passenger can be further subdivided.

Then, in the load value change monitoring step (S105), each load value at the time when the occupant wears the seat belt is monitored for a change over the first threshold value for the first time. Here, the first time may be set to, for example, 20 seconds, and the first threshold may be set to, for example, 1 kg.

Thereafter, the process proceeds to step S111 or step S107, depending on whether each of the load values changes over the first threshold value for the first time.

In the case where the load values are changed to the first threshold value or more during the first time in the load value change monitoring step (S105), or when the occupant does not use the seatbelt in the above-described sensing step S101 of wearing the seat belt, The process proceeds to the measurement step S107.

And the load values are measured during the second time in the load value measuring step (S107). Here, the second time may be set to, for example, 7 seconds so as to equalize the system start time in the same manner as the initialization timing (for example, 7 seconds) of the Airbag Control Unit (ACU) for controlling the air bag deployment.

Then, in the load value comparison step (S109), each of the load values is compared with the variable load values varied during a specific time period for a specific time after the second time. Here, the specific time may be set to three cycles, for example, an interval of 20 seconds, or may be set to one minute.

Each of the load values may be used to determine the posture of the occupant at a later stage when the variable load value is different from the second threshold value. In addition, when each of the load values is different from each of the variable load values and the second threshold value or more, it is re-measured during the first time period in the load value measurement step (S107).

Here, the second threshold value may be set to a load value of 10% based on the load value measured for the second time, for example.

Thereafter, in the load value comparison step (S109), when each of the load values is different from each of the variable load values and less than the second threshold value, or when the load values are monitored in the load value change monitoring step (S105) If it does not change to more than the value, the process goes to the posture determination step S111.

Then, the attitude of the occupant is determined by comparing the load values obtained in step S101 or step S109 with each other in the attitude determination step S111. Here, the posture of the occupant may be a normal seat, a frontal inclined posture, or a lateral inclined posture.

The forward bias is a posture when the occupant is sitting on the front of the seat, and the lateral bias posture is a posture in which the occupant is in one of the right and left directions of the seat It is in a sitting position. Herein, only the posture of the occupant is described as the normal seat, the frontal inclined posture, and the lateral inclined posture, but it is obvious that there are various other postures.

A detailed method of determining the posture of the occupant will be described later with reference to Fig.

Finally, when the collision of the vehicle is detected in the airbag deployment step S113, the airbag is deployed at different inflation pressures according to the type and attitude of the occupant.

Explaining the airbag deployment according to the type and attitude of the occupant, for example, if the type of occupant is adult and the occupant's posture is normal, the frontal airbag is deployed at the maximum inflation pressure.

When the type of the occupant is adult and the occupant's posture is the frontal inclined posture, the frontal airbag is deployed with inflation pressure smaller than the maximum inflation pressure.

When the type of occupant is adult and the occupant's posture is in the side-by-side position, the side airbag is deployed with inflation pressure smaller than the maximum inflation pressure.

When the type of occupant is infants less than six years old and the occupant's posture is normal, the frontal airbag is deployed with inflation pressure less than the maximum inflation pressure.

Do not deploy the front airbag or side airbag when the type of occupant is infants less than six years old and the occupant's posture is in a frontal deflection posture.

When the type of the occupant is an infant less than six years old and the occupant's posture is in a side-by-side position, the front airbag or the side airbag is not deployed or the side airbag is deployed with an inflation pressure smaller than the maximum inflation pressure.

Referring to FIG. 2, a method of determining a posture of an occupant in an airbag deployment method according to an occupant type and an attitude according to an embodiment of the present invention includes a step of determining a posture (S111) The first load value 25kg and the second load value 25kg are equal to each other when the first load value 25kg and the second load value 25kg are equal to each other and the third load value 10kg and the fourth load value 10kg are equal to each other, When the second load value (25 kg) is larger than the third load value (10 kg) and the fourth load value (10 kg), the occupant's posture is determined to be normal. At this time, when the collision of the vehicle is detected in the airbag deployment step S113, the frontal airbag is deployed with the maximum inflation pressure.

The first load value 15kg and the second load value 15kg are equal to each other and the third load value 20kg and the fourth load value 20kg are equal to each other when the occupant type is adult (for example, 70kg) When the first load value 15kg and the second load value 15kg are larger than the third load value 20kg and the fourth load value 20kg when the first load value 15kg and the second load value 15kg are equal to each other, do. At this time, when the collision of the vehicle is detected in the airbag deployment step (S113), the frontal airbag is deployed with an inflation pressure smaller than the maximum inflation pressure.

In addition, when the occupant type is adult (for example, 70 kg), the second load value 15 kg and the third load value 15 kg are equal to each other, and the first load value 10 kg and the fourth load value 10 kg When the second load value 15kg and the third load value 15kg are larger than the first load value 10kg and the fourth load value 10kg when the first load value 15kg and the third load value 15kg are equal to each other, do.

Although the method of determining the posture of the occupant is described as an adult case, the same method can be applied to a case where the occupant is less than six years old. In the case of infants less than six years old, Do.
