Traction Control and Total Driving Force Distribution Strategy for Electric Vehicles with Four in Wheel Motors based on PD-Fuzzy Control

In this paper, a torque distribution control for electric vehicles with an in-wheel motor installed each wheel is proposed in order to manage the traction operation of vehicle and avoid slip ratio from reach extreme values while moves into slippery surfaces. The driving force main controller system its consist two loop. PD-Fuzzy logic PI-control are applied as speed inner loop aim improving stability support wheels. To retain total requested force, strategies obtained when on road low friction coefficient surface. Also, it works yaw moment suppressor runs split surfaces which improves performance. dynamics simulated using Simulink-MATLAB Program. results simulation demonstrated effectiveness method.
