Abstract
Provided are a method and an apparatus for controlling the deployment of an airbag. The method includes steps of: determining whether a complex collision has occurred, based on collision-related physical quantities due to a vehicle collision; and adjusting a threshold value as a criterion for determining whether to deploy an airbag when the complex collision has occurred as a result of the determination.
Claims20
A method for controlling deployment of an airbag, the method comprising steps of:
- determining whether a complex collision has occurred, based on collision-related physical quantities due to a vehicle collision;
- and
- adjusting a threshold value, to produce an adjusted threshold value, as a criterion for determining whether to deploy the airbag when the complex collision has occurred as a result of the determination.
A method for controlling deployment of an airbag, the method comprising steps of:
- detecting a primary collision based on collision-related physical quantities due to a vehicle collision;
- comparing the collision-related physical quantities, detected during the primary collision, with a threshold value as a criterion for determining whether to deploy an airbag, and deploying the airbag according to a comparison result;
- detecting a secondary collision based on the collision-related physical quantities in a state in which the airbag is not deployed;
- adjusting the threshold value, to produce an adjusted threshold value, when the secondary collision is detected;
- and
- determining whether to deploy the airbag according to the adjusted threshold value, and deploying the airbag according to a determination result.
An apparatus for controlling deployment of an airbag, the apparatus comprising:
- a complex collision determination section that determines whether a complex collision has occurred, based on collision-related physical quantities detected by a collision detection unit;
- and
- a threshold value adjustment section that adjusts a threshold value, to produce an adjusted threshold value, as a criterion for determining whether to deploy an airbag when the complex collision determination section determines that the complex collision has occurred.
An apparatus for controlling deployment of an airbag, the apparatus comprising:
- a complex collision determination section that detects a primary collision based on collision-related physical quantities due to a vehicle collision, and determines that a complex collision has occurred when a secondary collision is detected within a preset time after the primary collision is detected;
- a threshold value adjustment section that adjusts a threshold value, to produce an adjusted threshold value, when the secondary collision is detected;
- and
- an airbag deployment control section that compares the collision-related physical quantities, detected during the primary collision, with the threshold value as a criterion for determining whether to deploy an airbag, deploys the airbag according to a comparison result, determines whether to deploy the airbag according to the adjusted threshold value when the secondary collision is detected in a state in which the airbag is not deployed during the primary collision, and deploys the airbag according to a determination result.
