Abstract
An occupant feature detection method and system, and a computer-readable medium, where the method includes: inflating a seat cushion airbag () with a gas of a first predetermined volume, and measuring a reference pressure formed by the gas of the first predetermined volume when no occupant is seated; measuring a first pressure formed by the gas of the first predetermined volume after an occupant is seated; and obtaining a first weight based on a difference between the reference pressure and the first pressure, and using the first weight as a reference weight of the occupant. The seat cushion airbag () disposed in the vehicle seat is used to calculate the weight of the occupant and determine a sitting position of the occupant based on the difference between the pressure in the seat cushion airbag () obtained when no occupant is seated and the pressure in the seat cushion airbag obtained when the occupant is seated. Therefore, a feature of the occupant may be identified without additionally providing a pressure sensor, so that a targeted protection strategy is set for each occupant.
