EVALUE - Testing and Evaluation Methods for ICT-based Safety Systems
Overview
Background & policy context:
Active safety systems are massively implemented into new vehicle generations and offer a high potential in decreasing road accidents. While testing and rating of passive vehicle safety are based on established and accepted methods and programmes, these are unavailable for active vehicle safety today. Thus it is difficult to assess the performance of those systems for industry, legislation and further stakeholders. In particular, the end customer cannot judge the active safety of different vehicles based on easy-to-understand ratings as they are offered by different NCAP programmes. This leads to a relatively low awareness of active safety systems and can hinder a higher market penetration.
Going forward to accident free traffic, evaluation and standardised testing methods of ICT-based safety systems are essential. The main focus of the proposed research project is to define objective evaluation and testing methods for ICT-based safety systems.
Objectives:
The project was based on safety systems used in today's vehicles and investigated the future upcoming ICT-based systems. It set out to identify evaluation and testing methods, especially for active safety systems, with respect to the user needs, the environment and economic aspects.
The presence of standardised test and evaluation methods allowed the assessment of a vehicle's overall safety performance with respect to the ICT-based safety systems. This possibility increased the public awareness of the benefit that ICT-based safety systems have on road safety. Widespread awareness of ICT-based safety systems' performance will lead to a higher degree of acceptance for such systems and thus to increased market penetration and ultimately to a reduction of road fatalities.
Methodology:
Based on accident statistics, relevant scenarios have been derived that represent the majority of accidents in which active safety systems could possibly mitigate the outcome. A vehicle was assessed by applying the procedures. Those shall be recognisable also by the end customer as critical situations that can happen at any time. One example is approaching suddenly congesting traffic or a similar, non-moving obstacle. The benefit of active safety systems (e.g. by automatic braking in this case) will thus be even more clear. Assessing the active safety of vehicles includes the interaction with the environment/infra-structure and driver actions. For both testing the vehicle as a whole and the systems in detail, relevant scenarios have been found and defined.
