Abstract:
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; wherein the airbag inflator unit comprises an airbag inflator connector connected between an airbag inflator of the airbag inflator unit and the control unit to apply the airbag deployment signal; wherein the control unit comprises an integrated controller for transmitting a self-diagnosing signal and an airbag controller for applying a self-diagnosing current to the airbag inflator connector upon receipt of the self-diagnosis signal from the integrated controller; wherein the integrated controller transmits a self-cleaning signal to the airbag controller for applying a self-cleaning current to the airbag inflator connector upon receipt of the self-cleaning signal from the integrated controller in accordance with a result of measured resistance of the airbag inflator connector detected by the resistance detection unit during the self-diagnosing to eliminate impurities on the airbag inflator connector.
