Optimal energy management and recovery for FEV

This paper briefly describes the latest achievements of a new functional vehicle system to overcome the range anxiety problem of Fully Electric Vehicles (FEV). This is primarily achieved by integrated control and operation strategies to optimize the driving range. The main focus of these control strategies is cooperated electric drivetrain and regenerative braking system. The diverse source of information with on-board and off-board sensors, including navigation system, satellite information, car-to-car, car-to-infrastructure communication and radar and camera systems are primarily utilized to maximize the energy efficiency and correspondingly the range of the FEV.

Safety Simulation in the Concept Phase: Advanced Co-simulation Toolchain for Conventional, Hybrid and Fully Electric Vehicles (

Modern vehicle powertrains include electronically controlled mechanical, electrical and hydraulic systems, such as double clutch transmissions (DCT), powerful regenerative braking systems and distributed e-Machines (EM), which leads to new safety challenges. Functional failure analysis of events such as the sudden failure of a DCT or EM, and the development and the validation of suitable controllers and networks, can now be evaluated using co-simulation techniques, from the early stages of product development. A co-simulation toolchain with a 3D vehicle and road model, coupled with a 1D powertrain model, is used to enable the definition of hardware and software functions, and also to support the rating of the Automotive Safety Integrity Level (ASIL) during hazard analysis and risk assessment in the context of ISO 26262. This innovative approach may be applied to a wide range of powertrain topologies, including conventional, hybrid electric and fully electric, for cars, motorcycles, light or heavy duty truck or bus applications.

Tank-To-Wheel CO2 Emissions Of Future C-Segment Vehicles

This paper presents the results of a tank-to-wheel CO2 emission study for the currently proposed framework of the WLTP. The study is based on a similar, comprehensive pre-study for the framework of the NEDC that was carried out in cooperation with EUCAR and published in July 2013 [1]. The pre-study analyses the future trend of tank-to-wheel CO2 emissions along the NEDC of a reference C-segment vehicle featuring a wide range of powertrain configurations from conventional to fully electrified concepts.

Durchgängige Methodik für Simulation und Messung des Diesel-Hybrid-Potenzials

In diesem Beitrag wird eine Methodik vorgestellt, mit deren Hilfe die Verbrauchspotenziale einer Hybridisierung mittels Simulation optimiert und anschliesend die Auswirkungen auf die eingesetzte Verbrennungskraftmaschine am Motorenprufstand ermittelt werden. Die Methodik ist das Ergebnis einer Kooperation des Instituts fur Verbrennungskraftmaschinen und Thermodynamik der TU Graz mit AVL List in einem Projekt des K2-Mobility-Programms am Kompetenzzentrum Virtual Vehicle.

Integrated methodology for simulation and measurement of the diesel hybrid potential

This article introduces a development method which enables optimization of fuel consumption potentials of hybridization by means of simulation. Moreover, impacts of hybridization on the internal combustion engine are identified at an engine test bed. The methodology is the outcome of a cooperation of the institute for internal combustion engines and thermodynamics at Graz University of Technology and AVL List within a project of the K2-Mobility-Program at Virtual Vehicle center of excellence.
