Safety Potentials of Advanced Driver Assistance Systems in Commercial Vehicles

Advanced driver assistance systems (ADAS) do not only promise higher driving comfort, but potential benefit for an increase of safety especially for commercial vehicles. Accidents with involvement of commercial vehicles normally have severe consequences. The Institut für Kraftfahrzeuge (ika) of the RWTH Aachen University with support from the Institut für Straßenwesen (isac) der RWTH Aachen University have investigated in cooperation with the Bundesanstalt für Straßenwesen (BASt) current and future ADAS for commercial vehicle in order to determine the potential for their benefit to increase road safety. Based on the acci- dents of official statistics and in-depth analysis of accidents from the GIDAS data base, relevant accident reasons are assessed systematically for a possible interference with selected ADAS. The qualitatively estimated safety potential results from the superposition of the main accident characterisation, the accident type and the accident category. A detailed estimation of the safety potential is conducted by means of simulations with the traffic flow simulation tool PELOPS. A benefit-cost analysis of the investigated systems is conducted.Application of Advanced Driver Assistance Systems in Commercial Vehicle

Assessing the impact of automated driving: needs, challenges and future directions

Automated driving in all its different forms is now underway and large European projects have been launched to investigate the effects in real life. Field Operational Tests are typically used to gather evidence to assess the impacts. The FESTA methodology was developed to design and conduct FOTs and analyse the outcomes. Currently the methodology is being updated to address the challenges of the upcoming pilots on road automation. The ultimate goal of performing automated driving studies is to gain insight into the impacts automation will have on transport and on society in general. In this paper we will explain how the series of FOT-Net (2008-2016) and the CARTRE (2016-2018) coordination and support actions address the development of a common methodology. Questions around the formulation of research questions, data analysis, user acceptance and impact assessment are addressed. One of the most important ways forward is the sharing of data, knowledge and experiences. Only by combining the knowledge sources will we be able to get a clearer picture of what the future impacts of road automation will be. FOT-Net has developed a data sharing framework and recommendations from this framework will be described

Ecodriver. D21.3: Powertrain Model Validation

This report describes the experimental validation of the powertrain models developed in the WP21. The experimental tests consider the dynamical model of the vehicle and also the energy consumption model. The structure of this report is divided into four parts corresponding to the four powertrain configurations described in WP21. Each part covers the powertrain model, its inputs and outputs, and provides an experimental plan with the associated results. The deliverable shows the appropriateness of the simulated powertrain models to the measured signals obtained on the equipped vehicles

State of the art and eVALUE scope

eVALUE will address the real function of ICT-based safety systems and their capability to perform the function through two courses of action: defining and quantifying the function output to be achieved by the safety system and developing the testing and evaluation methods for the ICT-based safety systems. The safety systems within the eVALUE scope are classified into four clusters: longitudinal, lateral and yaw/stability. The fourth cluster remains open for upcoming systems. Based on market availability and penetration rate, the consortium decided to focus on eight preventive or mitigating safety systems: ACC, FCW and CM by braking, in the longitudinal assistance domain; BSD, LDW and LKA, in the lateral assistance domain; and finally, ABS and ESC, in the yaw/stability assistance domain. Following the description of current test and evaluation methods, sensor technologies, system function output and ECUs globally applicable to ICT based safety systems, the report covers these technologies and components for the eight selected systems in detail. As a next step to this deliverable and according to the work plan, concepts for design reviews, physical vehicle testing as well as laboratory testing will be analysed. The result will be an in-depth understanding of the possibilities to investigate and evaluate the eight active safety systems within the first phase of the project. The different concepts will then support the decision about the development of the testing and evaluation methods that are able to point out the safety benefit of those systems in the most representative way
