Review on Direct Yaw Moment Control of Four-in-wheel Electric Vehicles

Abstract

Due to the four-in-wheel electric vehicle (IEV) has a small volume and high power density, IEV has become an important development direction. Compared to traditional vehicles, IEVs increase the motion freedom with four driving source and IEV direct yaw moment control (DYC) becomes a burning issue. DYC can be used to improve safety performance and operated portability due to the flexibility of the torque distribution and the possibility of continuous adjustment of the motor torque[1]. Meanwhile, DYC extends the safe driving range from an emergency transient driving condition to a higher speed [2].
