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.
