Ecodriving IFSTTAR

  1. 1. Institut français des sciences et technologies des transports, de l’aménagement et des réseaux www.ifsttar.fr Institut français des sciences et technologies des transports, de l’aménagement et des réseaux Ecodriving: a simple matter of energy use? O. Orfila, COSYS-LIVIC
  2. 2. Institut français des sciences et technologies des transports, de l’aménagement et des réseaux www.ifsttar.fr A definition of ecodriving Few energy reaches the wheel and we are spoiling it Ecodriving is a good way to use our leftovers
  3. 3. Institut français des sciences et technologies des transports, de l’aménagement et des réseaux www.ifsttar.fr Ecodriving definition proposal • Ecodriving is a set of driving technics, dealing with all driving tasks, aiming at minimizing the energy losses and/or emissions rate of the driven vehicle, from an origin to a destination, without trading-off safety nor total travel time. • Note: Ecodriving is a multi objective optimization process.

  5. 5. Institut français des sciences et technologies des transports, de l’aménagement et des réseaux www.ifsttar.fr Some of the ecodriving research questions • Can ecodriving famous golden rules, taken one by one: • Reduce the energy used by the concerned vehicle? • Reduce the emissions rates of the concerned vehicle? • Improve road safety for the concerned vehicle? • Reduce congestions? • Increase comfort? • Reduce traffic noise? • And what about a whole network?
  6. 6. Institut français des sciences et technologies des transports, de l’aménagement et des réseaux www.ifsttar.fr Practical obstacle • Driving constrained by traffic conditions • Other drivers may dislike to have an ecodriver in front of them • No incitation to ecodrive: • Human habits are difficult to change (Learning aspects) • Almost no benefit from car insurance compagnies • Driving trainers are more concerned about safety • Limited knowledge about ecodriving impact
