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-f006: Vehicle test for energy usage efficiency enhancement.

Mentions: The energy usage efficiency enhancement according to the proposed eco assist techniques is evaluated through real vehicle testing using the Vista 1.0 electric vehicle model as shown in Figure 6. The vehicle test is done in four different ways: Using the FTP-75 and NEDC driving cycles at the Dynamo Lab, and during a city driving cycle and a highway driving cycle on real roads. We have made our own profiles for the city driving cycle on a virtually real road, and for the highway driving cycle on a real road, but they were not sufficient. In a real-world experiment, there is always the danger of an accident during the test, and therefore it is impossible to control these factors for our convenience while driving. The driving time is too short in the city driving cycle, and it is not easy to emulate speed, acceleration, and deceleration patterns under the same driving conditions in the highway driving cycle. To establish our own driving cycles, we used the NEDC and FTP-75 driving cycles, which are officially used for emission certification and fuel economy testing of light-duty vehicles in the USA and Europe. These regulatory driving cycle tests are conducted using a dynamometer, which simulates “typical” trips in the city or on the highway.
