Worldwide, the automotive industry is being challenged to make dramatic
improvements in vehicle fuel economy. In Europe there are CO2
emissions penalties prorated by the degree to which vehicles exceed
mandated CO2 levels. In the United States, vehicle fuel
economy targets set by Congress in 2007 for 20 per cent fuel economy
improvement by 2020 are now being accelerated by the Obama
administration to 35.5 mpg by 2016 for a passenger car. Taking effect in
2012, the new rules set more aggressive fuel economy measures that will
require significant gains in engine and driveline efficiency, better
performance cabin climate control and the introduction of electric
hybridization. This 2nd Edition of Propulsion Systems for Hybrid
Vehicles addresses the electrification innovations that will be
required, ranging from low end brake energy recuperators, idle-stop
systems and mild hybrids on to strong hybrids of the power split
architecture in both single mode and two mode and introducing new topics
in plug-in hybrid and battery electrics. Important topics of the 1st
Edition are retained and expanded and some outdated material has been
replaced with new information.
