Fundamental Research on Range Extension Autonomous Driving for Electric Vehicle Based on Optimization of Vehicle Velocity Profile in Consideration of Cornering

摘要

Electric vehicles (EVs) have been intensively studied over the past decade, owing to their environmentally-friendly characteristics, however, their miles-per-charge is relatively short. To improve the miles-per-charge, the authors' group has proposed Range Extension Autonomous Driving (READ) system which minimizes the consumption energy by optimizing the velocity profile. This paper extends READ system to be applied to not only straight driving but also curvy road by modeling the vehicle rotation motion and the cornering resistance. The effectiveness of the proposed method is verified by simulations and experiments.
