The goal of this project is to implement a fuel-optimal energy management controller on a serial hybrid electric bus for public transportation built by HESS AG. The serial hybrid bus together with the energy management control system developed by the Institute of Dynamic Systems and Control consumes 25% less fuel than a comparable conventional diesel bus both cases evaluated on a real busline and in a standardized test procedure.
Aladin is a corporate research project of with industrial partner with the objective to develop a high efficiency, near-zero emission, micro combined heat and power unit appropriate for grid balancing.
To cope with the demand for lower fuel consumption and increasingly stringent emission legislation, diesel engines have become very complex systems. Model-based procedures to derive controllers and engine calibrations are thus crucial to curb the expense for the manufacturer. Our projects cover the air path, the combustion, as well as the exhaust-gas aftertreatment.
Energy Management of Hybrid Electric Vehicles
In this research project, we study the synthesis of energy management strategies for hybrid electric vehicles. Besides minimizing fuel consumption, many other design objectives need to be considered. The final strategies are then tested in simulation as well as on our hardware-in-the-loop test bench.
Hybrid Pneumatic Engine
Hybrid pneumatic engines can realize additional operating modes with air used as an energy buffer. This ensures an excellent drivability even for highly turbocharged engines. Our new engine has a sophisticated valve actuation which implies challenges for control. Our projects cover modeling and control tasks in simulation as well as experimental work.
Natural Gas Diesel Hybrid
Among all possible natural gas engines, the dual-fuel natural gas-Diesel engine is one of the most promising engine types. It has the potential of achieving Diesel-like efficiencies without the need for a lean nitrogen oxide aftertreatment system. It also benefits from the lower CO2 emissions of natural gas compared to diesel or gasoline.
On-board diagnostics (OBD) is the continuous monitoring of all emission-relevant sensors and actuators of an engine system. The goal of this project is to develop and improve algorithms to accurately monitor the static and dynamic properties of these sensors and actuators over the whole lifetime.
The project «SwissTrolley plus» aims to replace the diesel-powered auxiliary power unit of standard trolley buses with a high-performance traction battery. This replacement offers several advantages over state-of-the-art technology.
