  Autonomous Vehicles (AVs) are complex systems that drive in uncertain
environments and potentially navigate unforeseeable situations. Safety of these
systems requires not only an absence of malfunctions but also high performance
of functions in many different scenarios. The ISO/PAS 21448 [1] guidance
recommends a process to ensure the Safety of the Intended Functionality (SOTIF)
for road vehicles. This process starts with a functional specification that
fully describes the intended functionality and further includes the
verification and validation that the AV meets this specification. For the path
planning function, defining the correct sequence of control actions for each
vehicle in all potential driving situations is intractable. In this paper, the
authors provide a link between the Rulebooks framework, presented by [2], and
the SOTIF process. We establish that Rulebooks provide a functional description
of the path planning task in an AV and discuss the potential usage of the
method for verification and validation.
