    • The invention relates to a method for activating occupant protection systems in a motor vehicle in the event of a crash which puts the occupants of said vehicle at risk. A processor-based trigger system is used to evaluate signals of crash sensors and to actuate the occupant protection systems. The inventive method comprises the following steps: detecting and preprocessing, directly on site of the crash sensor mounting areas, signatures that are produced by impacts on the vehicle body by means of a crash sensor system comprising a plurality of similar multifunctional peripheral crash sensors which are located in various areas of the vehicle body, evaluating the preprocessed signatures or variables derived therefrom by means of a crash algorithm associated with the trigger system, in terms of kind, intensity, direction and time of the crash signatures and/or occupant risk signatures, and triggering the crash-relevant occupant protection systems at the respective time determined in terms of the achievable protective effect of the occupant protection system when an occupant risk threshold is exceeded. The invention also relates to a device and a crash sensor and a crash sensor system, comprising at least three similar multifunctional peripheral crash sensors, via which physically diverse signatures, produced by impacts on the vehicle body, are detected and preprocessed directly on site of the crash sensor mounting areas.
    • 在机动车辆乘员保护系统在发生碰撞的情况下被激活确实会将车辆的乘客处于危险之中。 一种基于处理器的触发系统评估碰撞传感器和致动乘客保护系统的信号。 签名确实通过由碰撞传感器系统的方式在车身的影响产生被检测和在碰撞传感器安装区域的现场直接预处理。 碰撞传感器系统包括位于车辆身体的不同区域的相似的多功能外围碰撞传感器的复数。 经预处理的签名或可变从通过与触发器相关联的系统,实物,强度,方向和碰撞签名和/或占用者的风险签名时间方面撞击算法的手段是评估衍生的。 崩溃相关的乘员保护系统在时间触发respectivement确定性中的乘员保护系统所能达到的保护作用而言开采当乘员风险超过阈值时。
