The embodiment of the invention discloses a lane-changing driving track planning method, device and equipment and a medium, and the method comprises the steps: determining a preset driving track within a preset lane-changing time based on a millimeter-wave radar signal, the first motion state information of the adjacent vehicle on the lane where the current vehicle is located and the second motion state information of the adjacent vehicle on the target switching target lane are obtained; based on the first motion state information and the second motion state information, planning solving of motion state planning of the current vehicle is carried out, and the optimal longitudinal speed sequence of the current vehicle within the preset lane changing time is obtained; and planning and solving the motion state of the current vehicle based on the optimal longitudinal speed sequence and the preset deviation value of the at least one transverse motion state parameter to obtain the optimal lane changing driving track of the current vehicle in the preset lane changing time, thereby realizing the transverse and longitudinal combined planning of the lane changing path. It is ensured that the solution of the quadratic programming problem can be found all the time in the path planning process, and the stability of path planning is improved.
