The invention relates to an automatic driving lane changing track optimization model, an automatic driving lane changing track optimization method and an automatic driving lane changing track optimization system. According to the actual space size of the current lane change, the actual situation of information processing time delay of the automatic driving vehicle is considered meanwhile, the transverse direction and the longitudinal direction of lane changing execution are combined for configuring a complete lane changing track optimization model in a lane changing execution process. Throughthe lane changing trajectory optimization model, the self-adjustment and trajectory optimization capabilities of the automatic driving vehicle are improved; real-time feedback optimization control iscarried out on the whole lane changing process; safe execution of lane changing is ensured; when the model is constructed, the operation characteristics of lane changing in an actual and changeable traffic environment are combined; therefore, it can be ensured that the operation parameters generated by the automatic driving lane changing trajectory optimization model are accurately attached to thelane changing execution traffic scene where the automatic driving vehicle is actually located, the defects that the difference between the constructed model and the actual traffic scene is large andthe constructed model cannot be directly used are thoroughly overcome, and the adaptability is high.
