Abstract
The present invention relates to a method for controlling a passenger restraint device. The method for controlling a passenger restraint device according to the present invention includes a first checking step and a first checking result for checking whether a pressure change detected by a pressure sensing sensor exceeds a first threshold value. A second checking step of checking whether the pressure change amount exceeds the second threshold value when the first threshold value is exceeded, and when the pressure change amount exceeds the second threshold value, when the second check result exceeds the first threshold value, Determining whether the difference between the one time and the time exceeding the second threshold is less than or equal to the set value, and if the difference between the time exceeding the first threshold and the time exceeding the second threshold is less than or equal to the set value, Performing deployment of the passenger restraint.

Description
The present invention relates to a control method of a passenger restraint device, and more particularly, to a control method of a passenger restraint device that can reliably determine the time of restraint deployment.
In general, a vehicle may crash front or side while driving. In this case, in order to detect a side collision of the vehicle, a pressure sensor capable of detecting a pressure change inside the door as shown in FIG. 1 is mounted, and a pressure change inside the door caused by deformation of the door in the event of a collision can be measured. have.
In addition, it is possible to determine the deployment of restraints such as airbags according to the measured pressure change. That is, the threshold value is set to a constant value in advance, and when the measured pressure change amount exceeds the threshold value, it is determined that the collision occurs, so that a restraining device such as an air bag can be deployed.
However, in the case of using a single threshold value that is a constant value, for example, in the case of 18kph and 20kph shown in Figure 1 do not exceed the threshold value, but in the case of 18kph because the collision type is different, In the case of 20 kph, the restraint device should be undeveloped, but it is difficult to distinguish it.
The present invention is to provide a passenger restraint control method capable of reliably deciding when a restraint device is to be deployed by efficiently distinguishing a collision in which a restraint of a vehicle should be deployed and a collision that should not be developed.
The passenger restraint control method according to the present invention includes a first checking step of checking whether a pressure change detected by a pressure sensing sensor exceeds a first threshold value, and when the first checking result exceeds a first threshold value, A second checking step of checking whether the pressure change amount exceeds the second threshold value, and when the pressure change amount exceeds the second threshold value, when the pressure change amount exceeds the second threshold value, the time exceeding the first threshold value and the second threshold value Determining whether the difference between the time exceeding the set time is less than or equal to the set value, and if the difference between the time exceeding the first threshold and the time exceeding the second threshold is less than or equal to the set value, Performing a deployment.
The method may further include detecting a pressure change inside the door by a pressure sensor provided at a side of the vehicle before the first checking step.
As a result of the determination, when the difference between the time exceeding the first threshold value and the time exceeding the second threshold value exceeds a set value, the passenger restraint device is undeveloped.
The method may further include setting the first threshold in advance and storing it in a storage unit before the first checking step.
The method may further include setting the second threshold value in advance and storing it in a storage unit before the second checking step.
The method for controlling a passenger restraint according to the present invention can efficiently distinguish between a collision in which a restraint of a vehicle is to be deployed and a collision that should be undeveloped, so that the restraint deployment time can be reliably determined.

3 is a view showing the pressure change detected by the pressure sensor according to an embodiment of the present invention.
A control method of a passenger restraint apparatus according to the present invention will be described in detail with reference to the accompanying drawings.
2 is a view showing a control method of a passenger restraint apparatus according to the present invention, Figure 3 is a view showing the pressure change amount detected by the pressure sensor according to an embodiment of the present invention.
Referring to the drawings, the control device of the passenger restraint apparatus according to the present invention checks whether the pressure change measured by the pressure sensor exceeds the first threshold shown in FIG. 3 (S202).
As a result of the check, when the pressure change amount exceeds the first threshold value, the control device of the passenger restraint device checks whether the pressure change amount exceeds the second threshold value shown in FIG. 3 (S204).
As a result of checking step S204, when the pressure change amount exceeds the second threshold value, it is checked whether the difference between the time periods exceeding the two threshold values is equal to or less than the set value (S206). For example, when the time difference exceeding two thresholds is T1 as shown in FIG. 3, it may be determined to be less than or equal to the set value, and the time difference exceeding two thresholds is T2 as shown in FIG. 3. In this case, it may be determined that the set value is exceeded.
Accordingly, when the difference in time exceeding the two thresholds is determined to be less than or equal to the set value, the control device of the passenger restraint device may perform deployment of the passenger restraint device such as an air bag (S208).
While the above has been shown and described with respect to preferred embodiments of the present invention, the present invention is not limited to the specific embodiments described above, it is usually in the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims. Various modifications can be made by those skilled in the art, and these modifications should not be individually understood from the technical spirit or the prospect of the present invention.
