The invention relates to an intelligent overtaking method and system for an automobile. The method includes the following steps that firstly, an overtaking system is started, the position information of vehicles around the vehicle is obtained through vehicle-mounted radar, and a planar coordinate system is set up; secondly, whether the overtaking conditions are met or not is judged; thirdly, the forecast running track of the front vehicle to be overtaken is obtained according to an online forecast algorithm; fourthly, the initial overtaking track of the vehicle is generated according to the forecast running track of the front vehicle; fifthly, whether overtaking is over or not is judged according to the position information, obtained in real time. of the front vehicle to be overtaken; sixthly, the position signal of the front vehicle to be overtaken is obtained continuously in real time, the running track is forecasted according to the online forecast algorithm, and the overtaking track of the vehicle is corrected in real time; seventhly, whether the acceleration of the front vehicle to be overtaken exceeds a corresponding threshold value or not is judged; eighthly, whether the value of K is equal to five or not is judged; ninthly, the intelligent overtaking system is shut down. Compared with the prior art, the intelligent overtaking method and system have the advantages that the overtaking safety is achieved, operation is simple, cost is low, and the algorithm is advanced.
