Energy Efficient Non-road Hybrid Electric Vehicles ― Advanced Modeling and Control

This book analyzes the main problems in the real-time control of parallel hybrid electric powertrains in non-road applications that work in continuous high dynamic operation. It also provides practical insights into maximizing the energy efficiency and drivability of such powertrains.

It introduces an energy-management control structure, which considers all the physical powertrain constraints and uses novel methodologies to predict the future load requirements to optimize the controller output in terms of the entire work cycle of a non-road vehicle. The load prediction includes a methodology for short-term loads as well as cycle detection methodology for an entire load cycle. In this way, the energy efficiency can be maximized, and fuel consumption and exhaust emissions simultaneously reduced.

Readers gain deep insights into the topics that need to be considered in designing an energy and battery management system for non-road vehicles. It also becomes clear that only a combination of management systems can significantly increase the performance of a controller.

Prof. Stefan Jakubek is head of the Christian Doppler Laboratory (CDL) for Model Based Calibration Methodologies at the Vienna University of Technology with research goals that include the development of new and integrated methodologies for model based calibration of automotive systems (combustion engines, powertrain systems, hybrid components) and the implementation of these methodologies in essential calibration tasks.

Johannes Unger, has research interests in the field of the control of the parallel hybrid electric powertrains as well as the modelling of the battery for the purpose of high accurate state of charge estimation with his research already published in high ranked scientific journals. Previously, Mr. Unger and Prof. Jakubek have collaborated in the field of order reduction with the aim of decreasing computational demands for controllers with their research awarded the “NRW Young Scientist Award 2012”.
