Abstract

This paper addresses a novel slip-ratio-based torque distribution strategy for electric vehicles (EVs) to avoid slippage when driving over a split friction surface. With the combination to an upper and middle controller, the desired driving force and yaw moment can be distributed to four driving wheels by utilizing the proposed lower controller. Stability analysis by using Lyapunov theorem is presented to show that the distribution method can equalize the slip ratios for the wheels on the same side of EVs. In addition, we also propose two torque distribution parameters for driving force KF and moment KM so that it is more flexible and easier to design a lower controller for EVs. This distribution method is able to equalize the slip ratios for wheels on the same side of EVs, so that the slipping motion can be avoided. Simulation results by using CarSim and MATLAB/Simulink are presented to show the performance of the proposed methods.
