Theoretical study on Eco-Driving Technique for an Electric Vehicle with Dynamic Programming

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 Eco-Driving technique based on the Dynamic Programming(DP). Optimal speed profile of an EV which minimizes amount of total energy consumption has been decided under fixed origin and destination, running time and track condition. DP algorithm can deal with such complicated condition and also can derive the optimal solution. Using the proposed method, simulations were implemented in some cases. Especially the author paid attention to the gradient road and simulated it. The optimization model was solved with MATLAB optimization toolbox.
