Fundamental Design Criteria for Logical Scenarios in Simulation-based Safety Validation of Automated Driving Using Sensor Model Knowledge

Scenario-based virtual validation of automated driving functions is a promising method to reduce testing effort in real traffic. In this work, a method for deriving scenario design criteria from a sensor modeling point of view is proposed. Using basic sensor technology specific equations as rough but effective boundary conditions, the accessible information for the system under test are determined. Subsequently, initial conditions such as initial poses of dynamic objects are calculated using the derived boundary conditions for designing logical scenarios. Further interest is given on triggers starting movements of objects during scenarios that are not time but object dependent. The approach is demonstrated on the example of the radar equation and first exemplary results by identifying relevance regions are shown.
