Abstract
A method for classifying an occupant weight of a vehicle is disclosed. When an occupant gets in to or gets off a vehicle, an occupant weight is quickly classified by relatively shortening time for classifying the occupant weight into a certain weight class, and when the weight is changed according to vibration of the vehicle or a movement of the occupant in a state that a vehicle seat is occupied by the occupant, time for re-classifying the weight class is lengthened to thereby prevent frequent re-classification of the occupant weight, and accordingly, the reliability of an occupant weight classification system can be enhanced.

16. A method for classifying an occupant weight of a vehicle comprising:
-
sensing a weight of an occupant seated in a vehicle and classifying the occupant weight into at least one weight class; and
changing a weight class after a pre-set first classification time lapses when the occupant enters or exits the vehicle, and changing a weight class after a pre-set second classification time lapses when the occupant remains in the vehicle though a change of weight is sensed. - View Dependent Claims (17, 18, 19, 20, 21, 22)

23. A method for classifying an occupant weight of a vehicle in which a weight of an occupant seated in a vehicle is sensed and classified into at least one weight classes,
wherein a time period for allowing a change of a weight class when a change in a weight of the occupant is sensed according to a movement of the occupant is longer than a time period for allowing the change of a weight class when a change in the weight of the occupant is sensed according to the occupant'"'"'s occupancy and vacancy of the vehicle seat.

28. A method for classifying an occupant weight of a vehicle in which a weight of an occupant seated in a vehicle is sensed and classified into at least one weight class,
each weight is classified by three weight classes based on a first reference value and a second reference value greater than the first reference value, and only when a change value of a weight sensed according to a movement of an occupant in a current weight class exceeds an error value based on the first and second reference values, a current weight class is changed, and a time period for allowing the change of the weight class according to the movement of the occupant is longer than a time period for allowing a change of the weight class according to the occupant'"'"'s occupancy and vacancy of a vehicle seat.
