This paper investigates torque split control (TS-control) and its application to electric vehicle IZA, equipped with Direct-Drive motors (DD-motor). Numerical simulation is used to study the dynamics of TS-controlled electric vehicles. Firstly, this paper introduces new laws of TS-control to improve the handling and stability of the electric vehicle with 4-wheel DD-motors. Secondly, the new laws of TS-control are applied and simulations are conducted using an electric vehicle model. Ramp-step response and frequency response of the yaw rate under the normal road conditions are calculated, and vehicle motion on low friction road are calculated. The results of calculations show that TS-control improves the performance of the vehicle compared to the vehicle without control.
