Optimized Torque Distribution Strategy for In-Wheel-Drive Electric Vehicles to Reduce Tire Wear

Compared with conventional vehicles, in-wheel drive electric vehicles (EVs) have many advantages like multi-degree of freedom (DOF) of control system, high efficiency and driving stability. Varieties of torque distribution strategies have been proposed, but there is hardly any research focusing on the problem of tire wear which has a large effect on vehicle´s economy and particulate matter (PM) emission. In this article, an optimized torque distribution algorithm aiming at reducing tire wear is proposed. Joint simulation is conducted between Carsim and Matlab/Simulink, which shows that the proposed distribution algorithm can reduce tire wear, meanwhile also contribute to the vehicle stability.
