Abstract
Vehicle manufacturers have traditionally focussed on improving engines and
developing alternate powertrains to reduce exhaust emissions. In parallel, ITS
technologies have been in development for over a decade, but they have always
been aimed at increasing safety and convenience. Now their potential to help
drivers achieve the best fuel economy and least emissions, a concept known as
"green driving" or "ecodriving" has been recognised. There are different ITS
systems that can contribute towards eco-driving. Broadly, they can be grouped
according to their role in the driving cycle.
Before driving - choosing the "eco-route"
Navigation systems, both embedded and portable, can be programmed to calculate
an "eco-route" to the destination. This route is the ideal combination of fast
and short routes, with the least fuel consumption and hence minimum emissions.
Whilst driving - advanced driver assistance (ADAS)
ADAS systems such as adaptive cruise control and intelligent speed adaptation
can help in keeping the vehicle within the environmentally friendly driving
zone and hence reduce harmful exhaust gases.
After driving - remote analysis
Telematics systems have the potential to record driving patterns in real-time
and to later analyse this data to provide driver-specific tips to reduce fuel
consumption.
These three technologies , including products currently available in the
market, are discussed in more detail in "Eco-driving - Harnessing the green
potential of ITS".
