Eco Assist Techniques through Real-time Monitoring of BEV Energy Usage Efficiency.

Kim Y, Lee I, Kang S - Sensors (Basel) (2015)

Bottom Line: For eco monitoring, the eco indicator and eco report are suggested to teach eco-friendly driving habits.The vehicle test, which is done in four ways, consists of federal test procedure (FTP)-75, new european driving cycle (NEDC), city and highway cycles, and visual feedback with audible warnings is provided to attract the driver's voluntary participation.The vehicle test result shows that the energy usage efficiency can be increased up to 19.41%.

ABSTRACT
Energy efficiency enhancement has become an increasingly important issue for battery electric vehicles. Even if it can be improved in many ways, the driver's driving pattern strongly influences the battery energy consumption of a vehicle. In this paper, eco assist techniques to simply implement an energy-efficient driving assistant system are introduced, including eco guide, eco control and eco monitoring methods. The eco guide is provided to control the vehicle speed and accelerator pedal stroke, and eco control is suggested to limit the output power of the battery. For eco monitoring, the eco indicator and eco report are suggested to teach eco-friendly driving habits. The vehicle test, which is done in four ways, consists of federal test procedure (FTP)-75, new european driving cycle (NEDC), city and highway cycles, and visual feedback with audible warnings is provided to attract the driver's voluntary participation. The vehicle test result shows that the energy usage efficiency can be increased up to 19.41%.

Mentions: As eco monitoring methods, the eco indicator and eco report are proposed as eco assist techniques. A short-term indicator is created to change the color (red, yellow and green) according to the level of energy usage efficiency. It gives the driver the current status information when excessive acceleration is detected or the vehicle speed exceeds the limit of a specific speed range in terms of the electric motor’s energy efficiency. A long-term indicator is provided by displaying a tree’s growth process to help drivers acquire intuitive eco-friendly driving habits. An energy usage efficiency indicator is used to provide the history of the driver’s energy usage patterns with the driver’s speed or acceleration pattern indicator as shown in Figure 4.
