The invention provides an intelligent driving lane changing track generation method and system, electronic equipment and a medium. The method comprises the steps that lane center line information is acquired; the lane center line information comprises coordinate information of each acquisition point of the lane center line and a lane line function expression correlation coefficient; determining a fitting coefficient of a lane center line according to the lane center line information; track compensation processing is carried out on the fitting coefficient in combination with lane changing time, road width and the current speed of the vehicle, and a compensation fitting coefficient is determined; and determining a lane changing track based on the compensation fitting coefficient. The invention provides the low-calculation-power lane changing track generation method, and the output lane changing track is stable and smooth without large noise, so that the intelligent driving requirement can be met.
