[en] Within the German Research Initiative INVENT, the partial project „Verkehrliche Wirkung,
Recht und Akzeptanz (VRA)“ deals with traffic effects, legal aspects, acceptance and
economics of driver assistance systems. The major focus is to accompany the development
of such systems rather than evaluating the systems at a later stage. This ensures that wrong
development paths are avoided from the beginning. This presentation gives examples for the
consulting services of VRA as well as for the early simulations of a driver assistance system.
Such simulations vary in scale from basic functions to driving situations, then to traffic
situations and finally to traffic scenarios. Results are presented for the basic functions and
driving situations for a stop-and-go extension of adaptive cruise control.
