Abstract
Electric vehicles are already a reality although their development and spread in urban context are encountering resistance especially due to the lack of electric vehicle charging facilities. Small electric in-wheel motors are perfectly suited to urban driving and their low electric energy consumption can also guarantee a sufficient daily mileage. The present paper proposes a rear wheel drive electric vehicle powered by two hub motors whose torque requests can be independently commanded by two separate inverters. This torque management fits well with a torque vectoring (TV) system that can improve the vehicle manoeuvrability, even at low speed. The TV can be implemented in a low cost programmable control board that can be used in any type of vehicle. The considered TV system was tested in a prototype quadri-mobile developed in an industrial research and development program called HiQuad.
