ABSTRACT
This paper proposes an efficient direct yaw moment control (DYC) capable of minimizing tyre slip loss on contact patches in an electric vehicle equipped with four-independently driven in-wheel motors (IWMs). Simulations identified a significant loss reduction due to a change in steer characteristics during acceleration or deceleration while turning. Simultaneously, the vehicle motion is also stabilized. As a result, the proposed control method can ensure compatibility between vehicle dynamics performance and energy efficiency. This paper also describes the results of a full-vehicle simulation that was conducted to examine the effectiveness of the proposed DYC.
