   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

4. 2. Novel powertrain topologies for energy-efficient battery electric vehicles

   Author : Yu Xu; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System simulation; Battery electric vehicle; Electric powertrain; Powertrain topologies; Vehicle performance; Energy efficiency;

   Abstract : The global transition towards sustainable transportation has underscored the importance of battery electric vehicles (BEVs), with a growing need for enhancement in powertrain energy efficiency to mitigate range anxiety and promote widespread adoption. In response to this need, there have been significant contributions from advancements on powertrain components, such as electric motors and inverters, towards increased energy efficiency. READ MORE

5. 3. Predictive Control of Hybrid Electric Vehicles on Prescribed Routes

   Author : Lars Johannesson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Management; Powertrain Control; Predictive Control; Dynamic Programming; Vehicle Telematics; Hybrid Electric Vehicle; Hybrid Electric Powertrains;

   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.
