Analyse der Motorreibung im Hinblick auf den neuen WLTC-Testzyklus

MTZ - Motortechnische Zeitschrift, 2017
With increasingly strict legislation and further the introduction of a new testing procedure WLTP, the highly detailed knowledge of engine friction becomes essential to obtain further fuel economy reductions. In the following, a novel engine friction testing method is used together with a highly accurate simulation to analyze engine friction exemplary ...

Analysis of temperature and altitude effects on the Global Energy Balance during WLTC

International Journal of Engine Research, 2021
In this work, the Global Energy Balance (GEB) of a 1.6 L compression ignition engine is analyzed during WLTC using a combination of experimental measurements and simulations, by means of a Virtual Engine. The energy split considers all the relevant energy terms at two starting temperatures (20°C and 7°C) and two altitudes (0 and 1000 m).

Centralized model‐predictive cooperative and adaptive cruise control of automated vehicle platoons in urban traffic environments

IET Intelligent Transport Systems, Volume 17, Issue 11, Page 2154-2170, November 2023., 2023
This paper presents a linear model predictive control (MPC) algorithm for the optimization of velocity trajectories of vehicles in a platoon in an urban traffic environment. A novel centralized approach is implemented to optimize the total energy consumption of all vehicles while improving traffic efficiency.
