A framework of the non-critical spontaneous intervention in highly automated driving scenarios

Abstract

One trend in the development of autonomous driving is to take the human completely out-of-the-loop. However, we believe that there are good grounds to keep the human in the loop, at some level of control (in particular tactical control), even in the case of full automation. One reason to do so is that the technology may not be flexible enough to always behave according to human needs and preferences, which may vary across people and situations. There are still many scenarios driver want to spontaneously intervene the behaviour of the system, e.g. picking up a friend in a crowded area, selecting a parking lot, that the driver would not like to follow a big truck and want to turn to another road to explore and find new places. In this paper, we present a framework of human intervention in Non-critical Spontaneous Situations (NCSSs). The framework facilitates a systematic definition of these scenarios, which ensures that all relevant aspects are addressed when eliciting requirements or validating concepts.
