摘　　要：为降低碰撞事故中安全气囊误起爆对乘员造成伤害,利用乘员特征图像识别,开发了针对不同乘员类型的智能安全气囊控制系统。该系统采用图像传感技术、融合多通道外部传感信息,识别乘员类型;依据划定的婴儿、儿童、5百分位成年女性、50百分位成年男性、95百分位成年男性等5种乘员类型,将安全气囊的泄气孔直径、起爆时刻、质量流量、拉带长度等参数调整到最优设计状态;从而在碰撞事故中对不同乘员类型均起到较好的保护效果。试验结果表明:该系统可跟踪车辆运行环境,自动地输出正确参数调整和点火控制信号。Pattern recognition was used to develop a complete intelligent control system for different feature types of occupants used to reduce occupant damages in case airbags are mistakenly ignited in vehicle collisions. The system uses image detection technology and integrates multiple external sensors to identify occupant feature types. The airbag control system adjusts parameters, including the deflation-hole diameter, the ignition time, the mass flow rate, and the strap length, to the optimal state according to five defined types of occupants, including infants, children, the 5th percentile female, the 50th percentile adult male, and the 95th percentile adult male to obtain protective effects for the different types of occupants in the vehicle collisions. Test results show that the intelligent control system automatically and properly outputs signals for adjusting parameters and ignition control while trailing to vehicle running environments.
