Abstract

The All-Wheel-Independent-Driving (AWID) electric vehicle has big potential to improve driving capability. To make full use of ground adhesive force to improve the driving capability, a dynamic model with 18 degrees of freedom (DOF) for 6WID electric vehicle is established in this thesis. A kind of torque distribution strategy based on load ratio is brought forward, with an antiskid PI control algorithm. The dynamic system model of the vehicle is co-simulated with Adams and Matlab/Simulink. The comparative experiment shows that this kind of driving force distribution strategy can improve the driving capability of the vehicle.
