COURSE 1: BASICS IN HYBRID ELECTRIC VEHICLES

Introduction to Hybrid Electric Vehicles – Basic Functions, Components & Operation8 - 10 July 2019

Dr. Thomas Riemer, FKFSDr. Thomas Riemer is Head of the department Automotive Mechatronics/Mobility at FKFS. He received his diploma in mechanical engineering from University of Stuttgart, Germany, in 2004 and his doctorate in mechanical engineering, also from University of Stuttgart, in 2011. His research focuses on the impacts of new forms of mobility on vehicle construction.

Hans-Jürgen Berner, FKFSHans-Jürgen Berner is Head of the department Automotive Propulsion Systems at FKFS. He received his diploma in mechanical engineering from University of Stuttgart, Germany, in 1992 and started at FKFS as a scientifi c assistant in the Internal Combustion Engines Department. In 1995 he became a group leader in this department, and in 1999 Division Head of Thermodynamics and Combustion Process Development. His fi eld of responsibility includes coordination of vehicle application, function development operating strategy hybrid powertrain and coordination of synthetic fuel-projects.

Course Objectives:This course fi rst gives an introduction to the specifi cs of hybrid electric vehicles, the components and the control of the drivetrain. It addresses automotive engineers wanting to expand their knowledge towards alternative drives.

Objective 3:

Topics of this course are:Hybrid drivetrain structuresLearn about the diff erences and characteristics of serial, parallel and power-split hybrid drivetrains. Understand the advantages/disadvantages of P0-P4 drivetrain structures in more detail.Electrical ComponentsAs the electrical components are the key diff erence with hybrized drivetrains, electrical machines, power electronics and batteries are covered.Operating internal combustion engines within hybrid drivetrainsThe use of hybrid drivetrains poses special demands for internal combustion engines in terms of operating point adaption, phlegmatization and cost optimization. In turn, this technology off ers new possibilities for the reduction of emissions and fuel consumption as well as for the improvement of drivability.Operational modesHybridized drivetrains feature several operational modes such as operating point shift, boost mode and recuperation due to the increased degrees of freedom. This also enables the realization of optimal regeneration modes for exhaust gas aftertreatment systems.Operational strategiesChoosing the right operational mode in each driving situation is a complex task that is executed by the hybrid operational strategy. An overview of various optimization targets and diff erent established strategies is given.Practical examplesAn overview of some prominent hybrid vehicles and their specifi c features is given.

Goals:After having completed this course, the participants will have fundamental knowledge about hybrid vehicle drivetrains and their specifi c characteristics. Key aspects are the understanding of the electrical components and the diff erences in operating the combustion engine within a hybrid drivetrain.

COURSE 2: VEHICLE AERODYNAMICS AND AEROACOUSTICSKnow-How in Theory, Measuring Technique and Testing10 - 12 July 2019

Goals:After having completed this course, the participants will have a fundamental knowledge about vehicle aerodynamics and aeroacoustics. They will be able to use high-tech aerodynamic and aeroacoustic measurement techniques and to carry out wind tunnel tests, both in order to eff ectively perform aerodynamic and aeroacoustic development work on cars and to consider the interfaces to other disciplines.

Dr. Andreas Wagner (as from 1 March 2019 Chair Professor of Automotive Engineering, University of Stuttgart)In 1999 Dr. Wagner received his diploma in automotive engineering from University of Applied Science Ulm, Germany. After additional studies on international economy in Ulm and on mechanical engineering at University of Stuttgart, he carried out driving stability research at the Institute of Internal Combustion Engines and Automotive Engineering (IVK, University of Stuttgart). In 2003 he received the doctorate (Dr.-Ing.) for his work on drivers‘ behaviour under cross wind conditions. From 2003 to 2019, Dr. Wagner worked for Audi AG, where he held several managing positions. He received the Kamm-Jante Award as well as the ECARA Award and he was
