ABSTRACT:
An airbag deployment controller and a passenger protection device including the same are provided to prevent erroneous (false) operation of an airbag due to noises and quickly deploy the airbag. The passenger protection device determines whether or not to drive an airbag unit, upon determining a detected value of a front acceleration sensor as being over a first collision threshold. Then, when determining to drive the airbag unit, the passenger protection device determines whether or not a detected value of a central acceleration sensor exceeds a second collision threshold. With the detected value being over the second threshold, it generates a driving signal and outputs it to the airbag unit in a final deployment control process. Thereby, the airbag unit operates an inflator to drive an airbag.
