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

Abstract

-Eco-driving technique for electric vehicles (EVs) is investigated in this paper.Many findings on EVs have been reported; however, they did not deal with eco-driving from the viewpoint of theoretical study. The authors have developed an energy-saving driving technique -the so-called "eco-driving" technique based on dynamic programming (DP). Optimal speed profile of an EV, which minimizes the amount of total energy consumption, was determined under fixed origin and destination, running time, and track conditions. DP algorithm can deal with such complicated conditions and can also derive the optimal solution. Using the proposed method, simulations were run for some cases. In particular, the author ran simulations for the case of a gradient road with a traffic signal. The optimization model was solved with MATLAB.

Optimal motion control for energy-aware electric vehicles

“…However, despite the variety of research on HEV/EV energy-aware systems, there is little work investigating HEV/EV motion control from a power management perspective, which is mainly because the relationship between vehicle dynamics and power consumption is complicated. In Kuriyama, Yamamoto, and Miyatake (2010) an "Eco-Driving" technique based on dynamic programming is developed for EVs seeking an optimal speed profile to minimize the amount of total energy consumption under fixed origin and destination, running time and track condition. Assuming a complete knowledge of the upcoming traffic light timing via infrastructure to vehicle (I2V) communication, De Nunzio, Canudas de Wit, Moulin, and Domenico (2013) address the problem of energyoptimal velocity profiles in urban traffic network.…”

Testing New Solutions for Eco-Driving: Haptic Gas Pedals in Electric Vehicles

“…Eco-driving is a recent campaign originated in Switzerland and Finland [2] and promoted by some European institutions whose main objective is teaching drivers an efficient driving style which allows them to reduce energy consumption and greenhouse gas emissions. There are different eco-driving strategies for Internal Combustion Engine (ICE) vehicles and Electric Vehicles (EV) because the characteristics of their power train efficiency are completely different [3] [4]. Some eco-driving strategies for EV have been proposed in the Energy Efficient Vehicles for Road Transport project (EE-VERT) [2] such as applying light but consistent pressure on the accelerator pedal, using the ECO mode for improved efficiency, applying early smooth braking which boosts regenerative braking, the use of Cruise Control (CC) to maintain steady speeds and using Recirculate Mode when Climate Control is on.…”

Eco‐driving at signalised intersections for electric vehicles

“…Despite of the excellent performances in energy‐saving and emission‐reducing, the development of EVs is still restricted by relatively short cruising range and limited infrastructural support [2]. There are various approaches to extend EV's cruising range, most of them have been focusing on route planning [3, 4] and navigation systems [5] or layout optimisation of charging infrastructures [6, 7], which provide EV drivers the information about energy‐efficient routes and recharging necessity.…”
