Approaching Safety-Argumentation-by-Design: A Requirement-based Safety Argumentation Life Cycle for Automated Vehicles
Marvin Loba, Robert Graubohm, Niklas Braun +6
Despite the growing number of automated vehicles on public roads, operating such systems in open contexts inevitably involves incidents. Developing a defensible case that the resid…
Towards an Argument Pattern for the Use of Safety Performance Indicators
Daniel Ratiu, Tihomir Rohlinger, Torben Stolte +1
UL 4600, the safety standard for autonomous products, mandates the use of Safety Performance Indicators (SPIs) to continuously ensure the validity of safety cases by monitoring and…
Conformal Prediction of Motion Control Performance for an Automated Vehicle in Presence of Actuator Degradations and Failures
Richard Schubert, Marvin Loba, Jasper Sünnemann +2
Automated driving systems require monitoring mechanisms to ensure safe operation, especially if system components degrade or fail. Their runtime self-representation plays a key rol…
Compensating for the Absence of a Required Accompanying Person: A Draft of a Functional System Architecture for an Automated Vehicle
Tobias Schräder, Torben Stolte, Inga Jatzkowski +3
A major challenge in the development of a fully automated vehicle is to enable a large variety of users to use the vehicle independently and safely. Particular demands arise from u…
A Taxonomy to Unify Fault Tolerance Regimes for Automotive Systems: Defining Fail-Operational, Fail-Degraded, and Fail-Safe
Torben Stolte, Stefan Ackermann, Robert Graubohm +4
This paper presents a taxonomy that allows defining the fault tolerance regimes fail-operational, fail-degraded, and fail-safe in the context of automotive systems. Fault tolerance…
Actuator Fault-Tolerant Vehicle Motion Control: A Survey
Torben Stolte
The advent of automated vehicles operating at SAE levels 4 and 5 poses high fault tolerance demands for all functions contributing to the driving task. At the actuator level, fault…
Towards Efficient Hazard Identification in the Concept Phase of Driverless Vehicle Development
Robert Graubohm, Torben Stolte, Gerrit Bagschik +1
The complex functional structure of driverless vehicles induces a multitude of potential malfunctions. Established approaches for a systematic hazard identification generate indivi…
Investigating Functional Redundancies in the Context of Vehicle Automation - A Trajectory Tracking Perspective
Torben Stolte, Tianyu Liao, Matthias Nee +2
Level 3+ automated driving implies highest safety demands for the entire vehicle automation functionality. For the part of trajectory tracking, functional redundancies among all av…
Identification of Potential Hazardous Events for an Unmanned Protective Vehicle
Gerrit Bagschik, Andreas Reschka, Torben Stolte +1
The project Automated Unmanned Protective Vehicle for Highway Hard Shoulder Road Works (aFAS) aims to develop an unmanned protective vehicle to reduce the risk of injuries due to c…
Model Predictive Control Based Trajectory Generation for Autonomous Vehicles - An Architectural Approach
Marcus Nolte, Marcel Rose, Torben Stolte +1
Research in the field of automated driving has created promising results in the last years. Some research groups have shown perception systems which are able to capture even compli…
Towards a Skill- And Ability-Based Development Process for Self-Aware Automated Road Vehicles
Marcus Nolte, Gerrit Bagschik, Inga Jatzkowski +3
The development of fully automated vehicles imposes new challenges in the development process and during the operation of such vehicles. As traditional design methods are not suffi…
Hazard Analysis and Risk Assessment for an Automated Unmanned Protective Vehicle
Torben Stolte, Gerrit Bagschik, Andreas Reschka +1
For future application of automated vehicles in public traffic, ensuring functional safety is essential. In this context, a hazard analysis and risk assessment is an important inpu…
