Theoretical study on eco-driving technique for an Electric Vehicle considering traffic signals

Eco-driving technique for Electric Vehicle (EV) is investigated in this paper. Many works on EV were reported; however they did not deal with the eco-driving from the viewpoint of theoretical study. The authors have developed the energy-saving driving technique so-called “eco-driving” based on the dynamic programming (DP). Optimal speed profile of an EV, which minimizes the amount of total energy consumption has been decided under fixed origin and destination, running time, and road condition. DP algorithm can deal with such complicated conditions and also can derive the optimal solution. Using the proposed method, simulations were implemented in some cases. Especially the authors paid attention to the road with traffic signals and simulated it without increase of calculation time.
