Preface
With the total number of vehicles steadily increasing and soon approaching
one billion, the world is facing serious challenges in terms of both safety of
road transport and sustainability. Consequently the two major persistent issues
for the automotive industry are improved safety and reduced emissions.
The estimated number of road fatalities is about one million per year. Fast
growth of mobility in the developing world and an accelerated urbanisation
pose high demands to the automotive industry. Thanks to smart systems
anticipating dangerous traffic situations road fatalities will have dropped by
more than 30% from 2001 to 2010.
Beyond intensive stock-rearing – with 30% the major contributor to climate
change – road traffic is one of the main sectors contributing to climate change:
exhaust gases from vehicle engines account for about 20% of the greenhouse
gas emissions. Car industry is bearing this challenge and enormous progress
has been achieved particularly during the last decade.
The integration of complex microsystems with enhanced intelligence, so-called
smart systems has enabled an increase of efficiency of the previously ‘dumb’
internal combustion engine by on average 1% annually during the last 20
years. In the future, smart systems may help to leverage novel powertrain
concepts towards the zero emissions vehicle. Particularly for electric vehicles,
anticipatory power management and efficient driving assistance by smart sys-
tems will be needed to overcome the range limitations. Adaptive systems pre-
dicting the energy demand for a chosen route will help the driver to increase
energy efficiency. Networked devices for car-to-car communication could help
to avoid the waste of energy due to unnecessary braking and accelerating.
Intelligent systems for tire monitoring and control deserve special attention
since insufficient tire pressure accounts for more than 3% of the efficiency
losses in the car. Future electrical in-wheel motors require new miniaturised
functionalities enabled by advanced micro- and smart systems.
Bearing in mind the particular needs of applications for the automobile, stake-
holders from the European Technology Platform on Smart Systems Integration
(EPoSS) recently compiled a list of future strategic research priorities for next-
generation smart systems. These include: advanced functionalities, energy
autonomy and networked operation, as well as matters of integration and
reliability in harsh environments. The tire monitoring system that comprises
an energy harvesting function for autonomous operation presented at the
