Abstract
A seatbelt control apparatus includes seatbelt control means that controls a motor for retracting a seatbelt; and motor current detecting means that detects a current of the motor. The seatbelt control apparatus further includes jamming determination means, indicator detecting means, and threshold value setting means. The jamming determination means determines whether or not the seatbelt is jammed during take-up operation on the basis of whether or not the motor current detected by the motor current detecting means exceeds a threshold value for jamming determination. The indicator detecting means detects an indicator of a current versus load characteristic of the motor. The threshold value setting means sets the threshold value for jamming determination on the basis of the indicator detected by the indicator detecting means.
