In order to meet the growing requirements on vehicle safety, additional safety systems are usually integrated that then fulfill a certain function. The function only becomes active in the defined use cases, since it could have a negative effect on the vehicle safety in other situations, or the necessity of intervention is not at all recognized. For the implementation of a traffic system without traffic fatalities, it is very difficult to implement this method, since an infinitely large number of situations have to be taken into consideration. In an integral safety concept, the individual safety systems are closely networked and act interdependently with each other. This paper will examine in simple scenarios whether it is possible to ensure accident-free driving such that the so-called Vision Zero can be realized in any case.

The protection of pedestrians from injuries by accidental collision is a primary focus of the automotive industry and of government legislation [1]. In this area, scientists and developers are faced with a multitude of requirements. Complex scenes are to be analyzed. The wide spectrum of where pedestrians and cyclists appear on the road, weather, and light conditions are just examples. Data fusion of raw or preprocessed signals for several sensors (cameras, radar, lidar, ultrasonic) need to be considered as well. Accordingly, algorithms are very complex. When moving from prototypic environments to embedded systems, additional constraints must be considered. Limited system resources drive the need to simplify and optimize for technical and economic reasons. With all these constraints, how can the safety functions be safe-guarded? This submission considers scene-based methods for the development of vehicle functions from prototype to series production focusing on functional safety.
