Passenger feature detection method and system and computer readable medium

Abstract

The invention provides a passenger feature detection method and system and a computer readable medium, and the method comprises the steps: filling a seat cushion airbag with a first predetermined volume of gas, and measuring a reference pressure formed by the first predetermined volume of gas when no passenger sits; measuring a first pressure formed by the first predetermined volume of gas after the occupant is seated; and obtaining a first weight according to the difference between the reference pressure and the first pressure, and taking the first weight as the reference weight of the passenger. According to the method, the seat cushion air bag arranged in the vehicle seat is utilized, the weight of the passenger is calculated and the sitting position of the passenger is judged according to different pressures of the seat cushion air bag when the passenger exists or not, so that the characteristics of the passenger can be recognized under the condition that no pressure sensor is additionally arranged and thus a targeted protection strategy can be set for each passenger.

Description

technical field [0001] The present invention relates to a detection method, a detection system and a storage medium for a vehicle, in particular to a detection method and system for occupant characteristics equipped with a seat cushion airbag and a computer-readable medium. Background technique [0002] With the development of the automobile industry, autonomous driving or autonomous driving has become the mainstream research direction in the future. With the continuous advancement of autonomous driving, the seating position of the occupants will present more possibilities. But safety during driving has always been the top priority. In automatic driving or autonomous driving, the occupant's attention may not be on the vehicle control or the road environment, so when there is a safety hazard, it may be difficult for the occupant to react in the first place, so automatic driving or autonomous driving usually An occupant protection system is provided to ensure occupant safety...
