The Influence of Driving Force Distribution on 4WID EV's Steering Performance

摘要

The dynamic steering model is built for the designed 4-wheel-independent-driven electric vehicle (briefed as 4WID EV),the steering experiment is done with 4-wheel driving force being equal and being not equal.With the trajectory and speed recorded,it is found that there is slip ratio in each wheel,and the change patterns resulted from driving force is given.The mathematic mode of 4WID EV is built with ADAMS software,the simulation of steering is done,the results being in accord with the experiment.In the further simulation,the driving force contribution mode with zero slip ratio is attained.
