摘要： An occupant feature detection method and system, and a computer-readable medium, where the method includes: inflating a seat cushion airbag (10) 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 (10) 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 (10) 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.

摘要： A control system and method for a pneumatic seat of a vehicle and a computer-readable medium, the pneumatic seat including a plurality of airbags (11, 12, 13, 14, 15, and 16) corresponding to different parts of the body of an occupant, where the control system further includes an information collection module (3), a determining module (4), and a control module (2), and the information collection module (3) is configured to collect motion information of the vehicle and/or external road information; the determining module (4) is configured to determine, based on the motion information and/or the road information, whether the vehicle satisfies either of a first condition and a second condition, where the first condition is whether continuous changes have occurred or are about to occur on a motion status of the vehicle in a first time period, and the second condition is whether a change range of the motion status of the vehicle in a second time period is or is about to be greater than a set threshold; and the control module (2) is configured to: when either of the first condition and the second condition is satisfied, control inflation and deflation of at least one of the airbags (11, 12, 13, 14, 15, and 16), to move the body of the occupant to be adapted to the motion status of the vehicle and/or a change of the motion status of the vehicle, to reduce discomfort caused by carsickness.
