3308 Fundamental Research on Range Extension Autonomous Driving for Electric Vehicle Based on Optimal Vehicle Velocity Profile in Consideration of Cornering

Abstract

Electric vehicle (EV) has been intensively studied in the last decade due to their environment friendly characteristics. However, the miles-per-charge of EV is shorter than that of internal combustion engine vehicles. To improve miles-per-charge, the authors' group has proposed Range Extension Autonomous Driving (READ) system which minimizes consumption energy by optimizing velocity profile. But conventional system can be applied to only straight driving. Therefore this paper extends READ to be applied to not only straight driving but also curvy road. The effectiveness of the proposed method is verified by simulations and experiments.
