Abstract: The ecological driving technology of ground vehicles is critical for energy-sustainable road
transportation. This technology, centered on the optimization and the coordination of driver, vehicle, road
infrastructure and traffic flow, aims to reduce the fuel consumption of vehicles in travelling by reshaping
drivers’ habits, assisting driving manipulation and implementing vehicular automation, etc. This paper
summarizes the key aspects of vehicular eco-driving technology, including its history, the state of arts and the
theoretical challenges. Two major identification methods of the eco-driving strategies are reviewed, i.e. the
experiment based method and the optimization based method. The applications can be classified into the ecodriving
education, the eco-driving assistance, and the eco-vehicular automation. The first item is easy to be
implemented and suitable for government promotion; the second item has most promising market prospect; and
the last item will become proper carrier for eco-driving technology with the popularity of vehicular automation.

Key words: vehicle engineering, ecological driving, driving assistance, fuel economy
