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%.

sensors-15-14946-f008: Test result (a) FTP-75 mode; (b) NEDC mode; (c) City mode; (d) Highway mode.

Mentions: In this paper, eco guide, eco control and eco monitoring methods are used as eco assist techniques, and the energy usage efficiency is improved by changing the driver behavior. The eco guide is provided for the driver to be able to control the vehicle speed and accelerator pedal stroke, and eco control is suggested to limit the output power of the battery without any driver input. For eco monitoring, the eco indicator and eco report are used to learn eco-friendly driving habits. The vehicle test result shows that the energy usage efficiency can be increased over 7% for the FTP-75 and NEDC driving cycles, and over 17% in the city and highway driving cycles when the driver adheres to all eco guides as shown in Figure 8 and Table 3. With respect to the regulatory driving cycles, they are standardized and prescribe certain speed and acceleration profiles, so we could not fulfill the specifications regarding maximum speed, average speed and trip distance.
