Continuous Evaluation of Methods for Sensor Data Fusion of Video-Based Driver Assistance Systems, Using Virtual Road Tests
The vehicle of the future will support drivers in critical situations and alert them to potential hazards by means of Advanced Driver Assistance Systems (ADAS). Sensor-based perception of the relevant traffic conditions and situation is essential in this context. The current evaluation approach of real-world road tests will no longer be sufficient due to the high complexity of the system interactions. New simulation methods are needed to test and evaluate ADAS, using virtual road tests with realistic vehicle behavior and a complex traffic environment. This paper describes a new simulation technology which has the capability of integrating virtual cameras in addition to the commonly known environment sensors (Radar, Lidar, ultrasonic) in the CarMaker vehicle dynamics simulation for functional testing of sensor data fusion algorithms.

X-in-the-Loop-Framework für Fahrzeuge, Steuergeräte und Kommunikationssysteme
Die Fahrzeug-zu-Fahrzeug- und die Fahrzeug-zu-Infrastruktur-Kommunikation sind wesentliche Treiber künftiger Mobilitätskonzepte. Dank dieser Technologien wird der Straßenverkehr sicherer, Verkehrsflüsse werden optimiert und Mobilität funktioniert künftig effizienter. Die dafür notwendigen Systeme sind neu. Ihre Durchdringung in Flottenversuchen fehlt daher. Dewegen sind Tests von Algorithmen, Parametern, Standards, Hardware und Implementierungen sehr aufwändig. Deren Wiederholbarkeit ist äußerst beschränkt. Das erfordert neue Werkzeuge und Entwicklungsmethoden sowie eine interdisziplinäre Betrachtungsweise. Die Autoren des Karlsruher Instituts für Technologie (KIT) und der IPG Automotive GmbH gehen mit gutem Beispiel voran.

Simulationsbasierte Homologation von Bremsen für Lkw-Anhänger
Ab 2011 müssen elektronische Fahrdynamikregelungen (ESP) innerhalb der EU in schwere Nutzfahrzeuge integriert werden. Angesichts der damit steigenden Zertifizierungsanforderungen ist nun der Einsatz von Simulationsmethoden
erlaubt. Haldex Brake Products und IPG Automotive realisierten die erste simulationsbasierte Homologation.
Geprüft wurden elektronische Stabilitätssysteme für Lkw-Anhänger gemäß der ECE-Regelung 13 / 11. Die Simulationssoftware TruckMaker eröffnet damit neue Möglichkeiten im Bereich des virtuellen Fahrversuchs.

Substantial Progress of Virtual Driver Skills in Interaction with Advanced Control Systems to meet the new Challenges of Vehicle Dynamics Simulation
In recent years, virtual test driving has become increasingly important in the automotive development process, mainly to increase efficiency, reduce costs and handle complexity.
The more chassis control and driver assistance systems are integrated in a vehicle the more load cases are necessary to test overall vehicle performance, system functions and fail-safe mechanisms. Open-loop maneuvers provide good indications about vehicle handling. Yet there must be a reason why test engineers continue to use the Nürburgring or public roads. The complexity of the maneuvers and test scenarios makes a generalized driver model approach very complex. The driver model has to cover a wide range of driving scenarios – from physical limit handling to reverse driving tasks in parking situations Fig. 1”. With a purely signal based approach (re-drive of profiles) such challenges could not be seriously addressed. Real-world test drivers are task driven based on clear test instructions, which must be fully reflected in a driver model, too.

Vorteile eines thermomechanischen Reifenmodells für die Fahrdynamik
Das von Michelin entwickelte thermomechanische Reifenmodell TameTire stammt aus der Formel 1 und stellt einen Fortschritt in der Fahrdynamiksimulation dar. Das Modell hat IPG in seine Simulationsplattform CarMaker integriert und um neue Funktionen erweitert. Bereits in der frühen Entwicklungsphase kann der Reifen in den Parameterraum der Fahrzeug-Reifen-Interaktion eingebunden werden, sowohl zur Zielerreichung als auch für Toleranzstudien.

The impending mandatory fitting of heavy commercial vehicles with electronic stability control and other advanced driver assistance systems in the European Union will result in a dramatic increase in development, testing and certification
requirements. Highly capable simulation tools have been specifically designed to
handle the enormous complexity of simulation to complement conventional realworld tests. Haldex and IPG Automotive achieved the first successful simulationbased homologation according to the requirements of the ECE 13/11 regulations.

V190_IPG_Michelin_TameTire_Paper_chassis.tech_201006.pdf
The thermal and mechanical tyre model TameTire, developed by Michlin, represents a new breakthrough in tyre modelling to simulate handling. IPG has integrated TameTire into its leading-edge CarMaker vehicle dynamics simulation platform. This article looks at the advantages which TameTire provides over state-of-the-art mathematical models for handling simulation, as well as its integration into IPG CarMaker.
