description PROBLEM TO BE SOLVED: To improve the accuracy of determination on whether or not an occupant protector is started in a starting control device of occupant protector. SOLUTION: A side collision sensor is disposed on a pillar of the side of a car body. The start or non-start of an air bag is determined depending on whether the acceleration of the side collision sensor exceeds a high threshold Th-High or not. The frequency components of acceleration od the side collision sensor are measured. When the relationship between the high frequency component and the low frequency component of the acceleration belongs to a region on the side where high frequency component appears at the initial stage of a collision, the threshold for starting the air bag is lowered, and the start or non-start of the air bag is determined depending on whether or not the acceleration of the side collision sensor exceeds a low threshold value Th-Low.
