1 Future mechatronical platform for easy application of assistant systems - EU-project PEIT PEIT - Powertrain Equipped with Intelligent Technology Feierlich wissenschaftliche Tagung der Ungarischen Akademie der Wissenschaften Nutzfahrzeugkonstruktionen und Verkehrssicherheit Retirement of Prof. Dr.-Ing. habil. Egon-Christian von Glasner Budapest, July1st 2003 Dr.-Ing. G. Spiegelberg

2 Motivation of PEIT Accident report In Germany alone about people / year are injured or lose life in accidents The most dangerous accident classes with heavy good vehicles involved are: - jack knifings, - trailer oscillations - roll overs - lane departures Goal : decreasing the numbers of accidents by 50 % until % preventable with an warning system 60 % preventable with an controlling system injured/killed people per year 2 / 2

7 7 / 2 What is PEIT? An european project financed by the european commission in the 5.th frameprogram Powertrain Equipped with Intelligent Technologies Running from September 2001 until September 2004

8 8 / 2 Goal of PEIT Motivation Improve overall traffic safety traffic efficiency for heavy goods vehicles accident prevention by the integration of intelligent technologies into a powertrain.

9 9 / 2 Objectives of PEIT General Objectives An overall improvement in safety with a fully electronically controlled powertrain. This is achieved by integrating: Centrally co-ordinated secure Drive-by-Wire platform New kind of Assistant Systems ESP with steering contro Show European Homologation path of PEIT approach Interface for easiest application of assistant systems
