The Research of Driving Force Distribution under Identical-State-Control while 4WID-EV Driving Straight
The strategy of 4-wheel-identical-state-control is proposed on the designed 4-wheel-independent-driven electric vehicle (briefed as 4WID-EV), the working states of each wheel are adjusted to be the same through controlling the ratio of drive-force and vertical-load on them as equal as possible, the co-simulation of ADAMS and Matlab/Simulink is done about the 4WID-EV driving on the straight flat road and slopes. The real vehicle test is performed. The result indicates that the strategy of identical-state-control can control each wheel slip ratio to be equal, make each wheel working in phase, reduce the power loss, improve the vehicle power property, and achieve the aim of good driving force distribution.
