The invention relates to a multi-objective optimization collaborative lane changing method based on vehicle dynamics, which comprises the steps that a collaborative lane changing control framework is established in a CAV vehicle control system, and the collaborative lane changing control framework comprises the arrangement of a longitudinal controller and the arrangement of a transverse controller; the setting of the longitudinal controller comprises the following steps: establishing a bicycle longitudinal dynamic model; designing a longitudinal controller; and solving the longitudinal controller. The setting of the transverse controller comprises reference trajectory generation; carrying out transverse dynamics modeling; establishing a prediction equation; setting constraint conditions; and establishing a target function. A first element in # imgabs0 # is used as an actual control increment to act on a CAV vehicle control system, thereby controlling the travel trajectory of the vehicle. According to the multi-objective optimization collaborative lane changing method based on the vehicle dynamics, a two-stage longitudinal and transverse independent control framework is provided, the operation difficulty of vehicle lane changing can be reduced, and the control efficiency is improved.
