    Abstract : Several aspects make today’s transport system non-sustainable:• Production, transport and combustion of fossil fuels lead to global and local environmental problems.• Oil dependency in the transport sector may lead to economical and political instability. READ MORE

  2. 2. Predictive Control of Hybrid Electric Vehicles on Prescribed Routes

    University dissertation from Chalmers University of Technology

    Author : Lars Johannesson; Chalmers tekniska högskola.; Chalmers University of Technology.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Automatic control; Farkostteknik; Vehicle engineering; Hybrid Electric Powertrains; Hybrid Electric Vehicle; Powertrain Control; Energy Management; Vehicle Telematics; Predictive Control; Dynamic Programming;

    Abstract : At the highest level in the powertrain control system in a hybrid electric vehicle an energy management controller interprets the driver’s pedal actions as a torque that is to be delivered at the powertrain output. The energy management controller distributes this torque between the engine and the electric machines and decides when to change gear and when to turn off the engine for pure electric propulsion.

    Abstract : Hybrid electric vehicles (HEVs), compared to conventional vehicles, complement the traditional combustion engine with one, or several electric motors and an energy buffer, typically a battery and/or an ultracapacitor. This gives the vehicle an additional degree of freedom that allows for a more efficient operation, by e.g. READ MORE

  5. 5. A Methodology for the Design of Cost Effective Hybrid Vehicles

    University dissertation from Chalmers University of Technology

    Author : Jonas Hellgren; Chalmers tekniska högskola.; Chalmers University of Technology.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk mekanik; Engineering mechanics; hybrid vehicle; hybrid electric vehicle; fuzzy logic; system engineering; optimal design; evolutionary algorithms; genetic algorithms; alternative powertrain; fuel cell vehicle; modeling; simulation; model car;

    Abstract : This thesis deals with system design of cost effective hybrid and fuel cell vehicles. Today (2004) the major disadvantages of these vehicles are increased complexity and component costs. However, the decrease in cost of electrical components and the environmental concern make these vehicles more and more competitive. READ MORE
