Analysis of advanced autonomous and infrastructure-based drivetrain control systems with minimized emissions and optimized driving comfort

摘要

This paper will first describe the project FORFAHRT. The aim of FORFAHRT is the identification and analysis of improved low- emission drivetrain structures for integration into a driver assistance system. Part of the assessment during the project will be DI spark-ignition engines, integrated starter alternator systems as well as different transmission concepts such as CVT transmissions or automated manual transmissions. The analysis focuses on "conventional" drivetrain components, not on hybrid or electric propulsion. The analysis is done with the sub-microscopic traffic simulation program PELOPS, which was developed at the "Institut fuer Kraftfahrwesen Aachen" in cooperation with the BMW AG. PELOPS models the fundamental elements of traffic-namely route, environment, driver and vehicle with highest accuracy. The second part of the paper gives first results of the project work. The achievable reduction in fuel consumption of an advanced vehicle control system which integrates traffic data and optimized drivetrain structure is finally described.
