The invention discloses a lane changing method capable of reflecting personalized behaviors of a driver. The method comprises the steps of 1 establishing a lane changing track planning model to obtaina lane changing planning track; 2 determining the optimal characteristic coefficient and the optimal reaction and operation time of the driver according to the actually collected lane changing trackof the driver and the lane changing planning track corresponding to the driver; 3 establishing individual behavior sample sets {x1, x2, x3,..., xn} of a plurality of drivers, and classifying the x1, x2, x3,..., xn through a clustering algorithm to obtain a clustering center value of each category; 4 performing steering characteristic working condition extraction on the actually acquired driving data of the driver, and identifying a category corresponding to the steering characteristic working condition; according to the category result and the clustering center value corresponding to the steering characteristic working condition, obtaining the personalized characteristic coefficient, personalized response and operation time of the driver of the category; and 5 obtaining a lane changing track reflecting the personalized behaviors of the driver according to the lane changing planning track.
