In order to prevent injury of the occupant of the passenger seat when a side airbag deploys, we have developed an occupant position detection system. It detects the occupant's head entering the side airbag deployment zone. If so, the side airbag operation is inhibited and an indicator light on the side airbag alerts the occupant to the improper sitting position. It detects accurately the occupant's size and the head entering the side airbag deployment zone, using an occupant identification algorithm and electrostatic capacity sensors under the seat trim cover which determine the dielectric around the seat surface. 相似文献

基于虚拟试验方法的气囊折叠方式对离位乘员损伤影响的研究 总被引:5,自引:2,他引:3
基于MADYMO软件建立了对称折叠和环向折叠安全气囊以及假人碰撞位置的虚拟试验模型。试验结果表明:环向折叠气囊对人体的主要损伤值都小于对称折叠气囊的相应值;试验中测得的所有损伤值都小于损伤评定参考值,并和有关实际试验的结果基本相同。虚拟试验是一种研究气囊折叠方式对离位乘员损伤影响的有效方法。 相似文献

The need for an embedded system that can fuse incomplete, inconsistent, and imprecise decisions from several sensing systems
is a crucial step in achieving an effective decision for occupant safety measures. This paper deals with the decision fusion
strategies of a multi-sensing embedded system to achieve significant enhancement in the reliability of occupant safety through
the fused decisions. Multi-sensing approaches to determine weight, vision, and crash sensing are developed for occupant detection,
classification, position calculation, and crash detection. A rule-based decision fusion algorithm is then developed to fuse
the multi-sensing decisions. The developed sensing systems are incorporated into an embedded device. To execute the embedded
system, a system interface between the software and hardware is developed using Lab Window/CVI with the C programming language.
The experimental results demonstrated that the real time operation of the embedded system validate the effectiveness of the
decision fusion algorithm, characterize the safety measures and monitor the decision application. Several events were tested
that prove the performance of the embedded system is robust towards occupant safety measures. 相似文献

侧面安全气囊和气帘是专门针对乘员进行保护的安全装置,在发生侧面碰撞的交通事故中能有效地减少乘员受伤害的程度.文章从2013年在国家轿车质量监督检验中心进行的,依据GB 20071-2006《汽车侧面碰撞的乘员保护》进行的侧面碰撞试验中,选取了10个车型,包括轿车和SUV,每个车型分别进行了有侧面安全气囊、气帘和没有侧面安全气囊的侧面碰撞试验,结果表明配备侧面气囊和气帘的汽车能对乘员头部和上部肋骨提供更好的保护,但对中部和下部肋骨的保护效果一般,可以看出侧面气囊和气帘能对乘员头胸部提供更好的保护. 相似文献

Motor vehicle passenger airbags have been proven to be effective for reducing the possibility of passenger injury during a crash. However, the inflation of the airbag sometimes causes serious injury when a passenger is positioned close to the airbag. The United States Federal Motor Vehicle Safety Standard (FMVSS) 208 requires the use of a low-riskdeployment (LRD) passenger airbag system. This paper proposes a newly developed airbag system comprising two slim airbags mounted on the instrument panel. A series of tests were conducted using the FMVSS 208 test procedures to demonstrate the effectiveness of the proposed system. It was found that the system not only satisfied the injury criteria of FMVSS 208, but was also effective for protecting passengers of all sizes. 相似文献
