A novel design of all-wheel independent steering using regenerative in-wheel motors for a four in-wheel-motor drive electric vehicle

摘要

For AWS of individual drive EV with four hub motors, study on differential control is carried out by means of regenerative braking. EV designed in this paper controls speed of various wheels by means of mode of regenerative braking to make wheel turning at various speed, and braking energy is recovered while steering is achieved, which is an innovative electronic steering scheme. Research is carried out for problem of steering differential on the basis of EV sample which has been designed, and a set of scheme for steering differential control of motor driving and regenerative braking based is designed, and feasibility of this scheme is verified through real vehicle test.
