A New Torque Distribution Control for Four-Wheel Independent-Drive Electric Vehicles

Torque distribution control is a key technique for four-wheel independent-drive electric vehicles because it significantly affects vehicle stability and handling performance, especially under extreme driving conditions. This paper, which focuses on the global yaw moment generated by both longitudinal lateral tire forces, proposes new to allocate torques motors. The proposed objective function not only minimizes usage, but also make increased use of each generate achieve quicker response. By analysis comparison with prior torque control, approach shown have better performance in hardware-in-the-loop simulations.
