In the next 20 years the share of small electric vehicles (SEVs) will increase especially in urban areas. SEVs show distinctive design differences compared to traditional vehicles. Thus the consequences of impacts of SEVs with vulnerable road users (VRUs) and other vehicles will be different from traditional collisions. No assessment concerning vehicle safety is defined for vehicles within European L7e category currently. Focus of the elaborated methodology is to define appropriate test scenarios for this vehicle category to be used within a virtual tool chain. A virtual tool chain has to be defined for the realization of a guideline of virtual certification. The derivation and development of new test conditions for SEVs are described and are the main focus of this work. As key methodology a prospective methodical analysis under consideration of future aspects like pre-crash safety systems is applied.

The ASSESS project is a European Commission co-funded project that aimed to develop harmonized and standardized assessment procedures for collision mitigation and avoidance systems. ASSESS was one of the first European projects which dealt in depth with the concept of integrated safety, defining methodologies to analyse vehicle safety from a global point of view. As such, the developed procedures included driver behaviour evaluation, pre-crash and crash system performance evaluation and socio-economic assessment. The activities performed for the crash evaluation focussed on the influence of braking manoeuvres in occupant positioning through dynamic braking manoeuvres with real occupants and Madymo and LS-Dyna simulations. The assessment of the passive safety protection level according to the results of the influence of the active systems is based on sled testing and full vehicle testing.

Towards an Aspect Driven Approach for the Analysis, Evaluation and Optimization of Safety Within the Automotive Industry

An approach will be presented how development projects for safety-related and software-intensive automotive systems can be controlled through the application of model-based risk assessment. Therefore specific control measures have to be developed, which represent the degree of fulfilment of several aspects of safety-related developments. The control measures are evaluated through the analysis of risk-reducing aspects, for which the process of identification and specification is described. Thus, a framework for the creation of a probabilistic and aspect-oriented risk-analysis model (AORA) for safety related projects within automotive industries is currently under development. With respect to the upcoming safety standard ISO 26262 the twofold approach focuses on both, the identification and specification of risk-reducing aspects within the development as well as the application of a probabilistic reasoning model.
