汽车或航空电子应用中的分布式传感器执行器系统必须严格满足安全要求。必须在开发过程和运行时监控这些实施。为此，我们提出了以数据为中心的故障分类、故障表示和测量验证概念。
在本文中，我们增强了我们的方法并描述了一种适用于永久评估可容忍故障级别的故障传播机制。基于常见的故障表示，每个组件的特征在于其对信号有效性的影响。如示例场景所示，所提出的矩阵表示法提供了一种灵活且强大的方法来实现和监视故障传播。
Distributed sensor-actuator-systems in automotive or avionic applications have to fulfill safety requirements strictly. Those implementation has to be monitored during the development process and on run-time. For this purpose we presented a data centric fault categorization, fault representation and measurement validation concept.
In this paper we enhance our approach and describe a fault propagation mechanism suitable for a permanent evaluation of tolerable fault level. Based on a common fault representation each component is characterized by its effects on the signal validity. As shown in an exemplary scenario the proposed matrix notation provides a flexible and powerful method to implement and monitor the fault propagation.
