当驾驶员退出驾驶任务时，当由智能汽车自动运输较长时间时，如果发生驾驶员接管请求，他们并不总是能够做出适当的反应。本文提出了两种方法，如何处理这个问题的范围内的功能安全的概念。此外，还解释了全自动驾驶辅助系统和自动驾驶辅助系统之间的区别。之后，提出了两种不同的策略，以达到安全状态的结果，系统边界跨越。在第一种情况下，通过驾驶员接管达到后退状态，在第二种情况下，通过自动主动故障安全机构达到后退状态。随后描述了用于监控和达到安全状态的必要部件及其在驾驶辅助系统的基本功能架构中的嵌入。在这方面，还特别注意到冗余问题。最后得出的结论是，这里提出的安全概念对于保证自动驾驶汽车的持久安全性至关重要，从而使自动驾驶功能在商业上为批量生产做好准备。
As drivers back out of the driving task, when transported automatically by an intelligent car for a longer time, they are not always able to react properly, if a driver take over request occurs. This paper presents two ways, how to deal with this problem within the scope of a functional safety concept. Thereto, the difference between fully automatic and autonomous driving assistance systems is explained. Afterwards two different strategies to reach a safe state in consequence of a system boundary crossing are proposed. In the first case the fall back state is reached by a driver take over, in the second case by an automatic, active fail-safe mechanism. Subsequently the necessary components for monitoring and reaching a safe state and their embedment in a basic, functional architecture of a driving assistance system are described. In this context, special regard is paid to aspects of redundancy as well. In the end it is concluded, that the safety concept proposed here is crucial for guaranteeing enduring safety in an automatically driving car and in consequence for making automatic driving functions commercially ready for serial production.
