  2. 11. Modeling and Control for Emission Management in Hybrid Electric Commercial Vehicles

    Author : Olov Holmer; Lars Eriksson; Christopher Onder; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Electrification of powertrains is a major trend in the vehicle industry. The reason behind this is mainly that electrification of a powertrain generally results in better fuel economy, by eliminating inefficient, low load, operation of the engine. READ MORE

  4. 12. Analysis and control of a hybrid vehicle powered by free-piston energy converter

    Author : Jörgen Hansson; Mats Leksell; Chandur Sadarangani; Anders Malmquist; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; free-piston energy converter; FPEC; series hybrid electric vehicle; SHEV; power management; energy management; powertrain evaluation; equivalent consumption minimisation; ECMS; linear engine; Electrical engineering; Elektroteknik;

    Abstract : The introduction of hybrid powertrains has made it possible to utilise unconventional engines as primary power units in vehicles. The free-piston energy converter (FPEC) is such an engine. It is a combination of a free-piston combustion engine and a linear electrical machine. READ MORE

  5. 13. Modeling and Optimal Control of Heavy-Duty Powertrains

    Author : Vaheed Nezhadali; Lars Eriksson; Giorgio Rizzoni; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Powertrain; transmission system; optimal control; modeling for control;

    Abstract : Heavy duty powertrains are complex systems with components from various domains, different response times during transient operations and different efficient operating ranges. To ensure efficient transient operation of a powertrain, e.g. READ MORE

  6. 14. Control and Optimization of Fuel Cell Based Powertrain for Automotive Applications

    Author : Qian Xun; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power distribution; Cut-off frequency; Fuel cell; Chance-constraint co-design optimization; Supercapacitors; Convex programming; Electric vehicles; Load disturbance compensator; DC-link voltage; Robust co-design optimization; Batteries;

    Abstract : Fuel cell powered electric vehicles, with fast-refueling time, high energy density, and zero CO2 emissions, are becoming a promising solution for future fossil-free transportation. However, the relatively slow dynamic response and the inability of recovering the regenerative energy make vehicles solely powered by fuel cells not an immediately attractive solution. READ MORE

  7. 15. Motion modelling and control strategies of over-actuated vehicles

    Author : Johannes Edrén; Annika Stensson Trigell; Jenny Jerrelind; Mats Jonasson; Dongpu Cao; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : With the growing concern for environmental change and uncertain oil resources, the development of new vehicle concepts will in many cases include full or partial electric propulsion. The introduction of more advanced powertrains enables vehicles that can be controlled with a variety of electric actuators, such as wheel hub motors and individual steering. READ MORE
