SAFIR Cluster 2: Test methods for global safety

In addition to simulations, real driving tests are indispensable for testing systems that autonomously intervene in the longitudinal or lateral dynamics of a vehicle. Due to the high costs of real-life tests, it is necessary to identify a few “relevant” function-specific test scenarios, implement them reproducibly in the vehicle and evaluate them afterwards. Simulations can be used (SC1) to identify and analyse the “relevant” test scenarios, as well as data from traffic scenarios that are recorded when driving on public roads. As part of SAFIR, therefore, SC2 also involves research into components that are necessary for driving tests and their evaluation. At the same time, SC2 also focuses on establishing a testing system for driving on public roads. The goal is to created an automated and safe real-life test for Vehicle Safety 4.0.

This cluster is currently working on Impulse Project 2 “Test methods using driving tests for global safety”. In addition, two so-called SME projects are planned.

Impulse Project 2: Test methods using driving tests for global safety

In IP 2, research is being carried out into basic components for the automated testing of integral safety systems by means of real driving tests as well as a testing system for the reduction of road mileage in field tests. One main goal is optimisation and operation by combining the essential components required for high-precision, reproducible driving tests in indoor and outdoor test areas. The implementation of automated driving tests for integral vehicle safety up to the dynamic threshold range is to be realised in this way. A further important goal is to reduce field test road mileage by means of specifically selected driving routes or by driving tests on test sites.

The impulse project is subdivided into the following subprojects:

SME projects

2D Mover: movement platform for realistic pedestrian dummies

The aim of the SME project “2D Mover – movement platform for realistic pedestrian dummies” run by Messring GmbH is to create a mobile set-up for testing and validating the functionality of driver assistance systems. The 2D Mover mimics the macro-movements of pedestrians and cyclists, thereby enabling realistic mapping of those road users who are most at risk.

Using a number of winches, a platform on which a test specimen in the form of a target or dummy is attached is able to travel two-dimensional trajectories. The aim is to reproduce near-collision or collision situations with a moving vehicle in order to test its driver assistance systems and to investigate its response and behaviour. The 2D Mover is to be mobile and not have any specific structural prerequisites so that it can be flexibly set up at test sites. It is controlled by means of a notebook and triggered by DGPS or light barriers.

Optimisation of a real-time reference system for ADAS and AD tests (real-time reference)

In the SME project being conducted by GeneSys Elektronik GmbH, a measuring technique is to be developed that can reliably and precisely record the movements and position of a vehicle in real time without additional external sensor fusion, even in difficult environments such as where there is poor GPS reception or none at all. New methods for improving the robustness and accuracy of position detection for real-time applications are to be implemented. In addition, a reliable quality evaluation of the signal quality is to be developed and released.
