The invention relates to a full-electric-vehicle starting shaking control method based on a whole-vehicle simulation model. The full-electric-vehicle starting shaking control method comprises the steps that A, a whole-vehicle multi-body dynamic model of a full electric vehicle is built, and all transmission paths of starting shaking are obtained; B, a starting shaking motivated transmission path is determined, and the built whole-vehicle multi-body dynamic model is utilized for simulating a starting shaking phenomenon to determine the contribution of all the transmission paths to starting shaking; and C, the torsional vibration active control based on the feed-forward and feedback control is adopted in the starting shaking motivated transmission path, meanwhile, mounting suspension systems based on the active control are sequentially adopted in the other transmission paths according to the magnitude of the contribution to achieve passive control, and starting shaking is reduced. Compared with the prior art, the suspension systems and a transmission system are comprehensively considered, and the whole-vehicle shaking characteristics of the electric vehicle are reflected wholly.
