The invention discloses an automatic lane changing method and system based on a Bezier curve algorithm and a vehicle, and the method comprises the steps: obtaining the road map information of a road where the vehicle is located when a lane changing operation instruction is received, and converting the road map information into a three-lane road model if the road map information meets a preset lane changing condition; calculating based on the three-lane road model to obtain a plurality of Bezier curve control points, and obtaining a Bezier curve according to all the Bezier curve control points; and an automatic lane changing track is generated according to the Bezier curve, and a vehicle is controlled to change a lane according to the automatic lane changing track. According to the method, the semi-combination point of the target clutch can be accurately and adaptively adjusted, so that the gear shifting process is smoother and more natural.
