Modeling, control and diagnosis of diesel engines

Due to the increasing customer requirements and more stringent emission regulations the combustion engine is increasing in its complexity. Besides the engine performance the emissions and the reduction of fuel consumption during stationary and dynamic driving possesses significant relevance.
The Institute of Automatic Control develops new structures for the open and closed loop control of combustion engines. These can be tested on several simulation systems, e.g. Hardware-in-the-Loop Simulator at the dynamical engine test bench. Besides the control, the model-based fault diagnosis (On-Board-Diagnosis) has also become a main issue.

Control of vehicle dynamics, driver assistance systems

The increasing usage of mechatronic components for automotive steering systems, brakes and suspensions together with the electrification allows new ways for automatic driving control systems. Therefore our research projects deal with the modeling, state-estimation and identification of driving vehicle dynamics and applications for controlling vehicles for driver assistance systems and automatic driving.
