CALIBRATION APPARATUS FOR AIRBAG INFLATOR RESISTANCE
First Claim
1. A calibration apparatus for an airbag inflator resistance, comprising:
- an airbag inflator unit for applying an airbag deployment signal;
a resistance detection unit for detecting a change in the resistance of the airbag inflator unit; and
a control unit for self-diagnosing and self-cleaning the airbag inflator unit according to the result measured by the resistance detection unit.

Abstract
Disclosed is a calibration apparatus for an airbag inflator resistance. The calibration apparatus for an airbag inflator resistance includes: an airbag inflator unit for applying a deployment signal for deployment of an airbag; a resistance detection unit for detecting a change in the resistance of the airbag inflator connector; and a control unit for self-cleaning the airbag inflator connector in accordance with the resultant resistance detected by the resistance detection unit. The calibration apparatus is effective in preventing malfunction of an airbag warning light and ensuring reliability by preventing an increase in resistance due to the contamination of the airbag inflator by the self-diagnosing and self-cleaning effect using an electric current.

11. A method for controlling a calibration apparatus for an airbag inflator resistance, comprising first self-diagnosing and self-cleaning steps of:
-
measuring a resistance of an airbag inflator connector; comparing the measured resistance of the airbag inflator connector with a reference resistance; and applying a current for first self-cleaning the airbag inflator connector if the measured resistance is higher than the reference resistance. - View Dependent Claims (12, 13, 14)
