Each seat in the vehicle is also equipped with a seat belt buckle tension sensor and a pre-tightened force-limiting seat belt. The seat belt buckle tension sensor can determine the occupant's posture information according to the tension of the seat belt. The difference between the force seat belt and the ordinary seat belt is that the pre-tightened seat belt is characterized by that when the car crashes and the occupant has not moved forward, it will first tighten the webbing according to the set force limit value.

Here, the third preset weight can refer to the weight of the 50% male dummy (75kg), and the third category is the occupants with heavier weight in the back row. Correspondingly, in an optional implementation manner in which the ignition parameter of the airbag and the force limit value of the pre-tightened force-limiting seat belt are determined according to the category information, the force-limiting value is determined to be the first preset force-limiting value.

Correspondingly, in an optional implementation manner in which the ignition parameter of the airbag and the force limit value of the pre-tightened force-limiting seat belt are determined according to the category information, the force limit value is determined to be the second preset force limit value. In this way, for occupants with heavier weight in the rear, the seat belt force limit value is set to the high limit force value to strengthen the restraint force on the occupants.
