A novel eco-driving application to reduce energy consumption of electric vehicles

Electro-mobility is becoming increasingly important in nowadays transportation systems. However, due to the limited range of electric vehicles, drivers need to adopt an energy-efficient driving attitude. In this paper, we present a novel eco-driving application that informs the driver about his energy efficiency. We implement an Android application that is able to gather relevant data from the vehicle´s CAN bus using an OBD Bluetooth adapter. We evaluate the retrieved data together with topographic information retrieved from the Internet in order to provide the driver with a representative eco-score based on a Fuzzy-System. In order to validate our approach, an experimental evaluation is proposed for different drivers in a predefined path. The results show that the computed eco-score accurately reflects driving efficiency. Further, we show that eco-driving concepts can significantly reduce the overall energy consumption and thus extend the electric vehicle´s range.
