Electric vehicles (EVs) have been intensively studied in the last decade due to their environment-friendly characteristics. However, the miles-per-charge of EVs is less than that of internal combustion engine vehicles. To improve the miles-per-charge, the authors' group proposed a Range Extension Autonomous Driving (READ) system that minimizes consumption energy by optimizing the velocity profile. However, conventional systems can be applied to driving on only straight roads. Therefore, this study extends READ system to be applied to driving not only on straight roads but also on curved roads by modeling the vehicle rotation motion and the cornering resistance. The effectiveness of the proposed method is verified by simulations and experiments.
