Research topics

Current research focuses at the Institute of Vehicle Safety at Graz University of Technology are the safety of vehicles with varying degrees of automation, the safety of vulnerable road users, the safety of alternatively powered vehicle concepts and the analysis of specific leisure and sports accidents.

The basic principles required for this are developed through basic research in the interdisciplinary fields of "Safety aspects of electrical energy storage systems", "Accident research", "Modelling of human beings with a focus on trauma biomechanics" and "Structural behaviour of (bio)materials in a crash. In each of these fundamental areas, investigations are carried out both by means of numerical simulations (e.g. explicit finite element simulations) and experiments. A large number of data analysis methods (e.g. machine learning) are also used, which are constantly being improved.


Accident Research

  • Accident reconstruction and analysis of road accidents (e.g. CEDATU - Central Database for In-Depth Accident Study)
  • Development of assessment tools for evaluating accident prevention systems
  • Development and evaluation of vehicle-specific and infrastructural measures to prevent accidents and reduce the severity of injuries
  • Derivation and evaluation of (critical) traffic (accident) scenarios
  • Targets for the development of future security strategies
  • Effectiveness assessment of current and future accident prevention and accident consequence reduction systems


Human modelling with a focus on trauma biomechanics

  • Analysis and modelling of human behaviour before and during accidents (traffic, leisure, sport)
  • Performance of tests with volunteers to analyse muscle activity and kinematics in the pre-crash phase
  • Analysis of injury mechanisms
  • Analysis of injury risk and related injury criteria
  • Further development and application of numerical human models for the evaluation of measures to reduce the risk of injury
  • Considering human diversity and the behaviour of different road users
  • Use of numerical human models for virtual testing (Euro NCAP Pedestrian Human Model Certification)

Safety aspects of electrical energy storage systems

  • Evaluation of the hazard potential of new but also aged lithium-ions (state-of-the-art anodes and cathode materials, all-solid-state batteries, 2nd life batteries) in crash situations (SafeBattery)
  • Analysis of multiphysical mechanisms in lithium-ion cells under crash load
  • Analysis of the thermal runaway propagation behaviour of lithium-ion modules
  • Safe integration of high-voltage battery systems in vehicles
  • Analysis of possible critical load cases
  • Performance of quasi-static, dynamic tests and electro-thermal tests with lithium-ion batteries with a SOC of 0% to 100% in the BSCG - Battery Safety Venter Graz (commissioning in 2020)

Structural behaviour of (bio)materials in a crash

  • Crash behaviour of sustainable materials (WoodCar)
  • Modelling and testing of road restraint systems
