Predictive Autonomy Lab

Empirical driver research experiments driven by safety engineering

The Predictive Autonomy Lab (PAL) provides a simulation environment to explore how humans interact with automated driving systems – focusing on the relation to safety risks identified through systematic safety engineering.

Empirical research infrastructure for safety and driving behavior research

In our driving simulator laboratory, we conduct empirical research on driver behavior from a safety perspective. Using safety engineering methods, we investigate safety‑critical driving situations to build and apply actionable safety knowledge. The simulator enables more accurate modeling of driver behavior by accounting for the external environment and interactions with other road users. These causal insights into human decision‑making improve the performance of driving automation systems. We also design and evaluate warning and intervention strategies that explicitly consider environmental influences on risk and safety, making them more timely, precise, and effective.

At the Predictive Autonomy Lab, Fraunhofer IESE offers safety-motivated research that ensures compliance with current standards and enables cost-efficient safety argumentation through validated driver behavior models.

Situation-sensitive and risk-aware driver monitoring for safe DCAS

There is a lack of accurate and safe driver monitoring systems that meet the driver’s expectations. Drivers who monitor DCAS are prone to distractions. However, today's DMSs remain limited: they assume worst-case driving situations, rely solely on data from inside the vehicle, and use simplified warning and intervention logic. This leads to frequent false alarms that frustrate and confuse drivers and undermine market acceptance, while rapidly evolving safety regulations make continuous compliance increasingly difficult.

Our situation-sensitive and risk-aware driver monitoring approach can increase customer acceptance and satisfaction. It helps you to design better DMS solutions embedded into the safety engineering processes while benefiting from the relation between identified safety risks and the behavior of the driver in its supervision task.

 

Our concrete value propositions

  • More accurate and realistic assessment of the driver’s engagement in its supervision task while using DCAS
    • Considering the current driving risk and the external driving situation
    • Analyzing the shortcomings of the DCAS as additional input
    • More detailed evaluation of the driver’s supervision
  • Sophisticated warning and intervention strategies for higher user acceptance and higher system availability
    • Intelligent warning and intervention strategies supporting the driver instead of hindering him
    • DCAS system adaptations as additional strategy
  • Part of the established systematic safety engineering and dynamic risk management processes

Method for designing situation-sensitive and risk-aware DMS

  • Driven by safety goals and embedded into the safety concept
  • Based on state-of-the-art dynamic risk management concepts
