UC2.1 – Safety assessment & decision making
Use Case 2.1 involves testing the SUNRISE SAF with an AD function that controls the ego-vehicle in a traffic jam scenario. The system is expected to control both its longitudinal and lateral position by a combination of braking, and steering commands. All of this is expected to happen while respecting a few constraints, such as a maximum longitudinal speed and a distance to the vehicle in front of the subject vehicle.
Use case overview
UC2.1 tests a Traffic Jam Chauffeur (TJC). This system manages both longitudinal and lateral motion via braking and steering, ensuring expected behavior under constraints like maximum speed and front vehicle distance.
Objectives
UC2.1 focuses on validating AD behavior by optimizing the workflow from scenario creation (Query & Concretise), execution (Execute), evaluation (Test Evaluation), to ensure robust collision avoidance against challenges like cut-ins and VRUs.

Safety case setup
This use case involves multiple partners and includes simulation, proving ground, and public road testing. Demonstration scenarios reflect highway traffic jams and follow UN Regulation No. 157.
