Range Extension Control System for Electric Vehicle during Acceleration and Deceleration Based on Front and Rear Driving/Braking Force Distribution Considering Slip Ratio and Motor Loss

Abstract

Electric vehicle have become a universally recognized solution for future green transportation. However, the mileage per charge of the EVs is lower than that of internal combustion engine vehicles. In this paper, a model-based range extension control system (RECS) for acceleration and deceleration modes is proposed. In this proposed method, slip ratio, copper loss, and iron loss are considered. The total driving-braking force is distributed based on the vehicle acceleration and velocity. The effectiveness of the proposed method is verified through simulations and experiments.
