The embodiment of the invention provides an overtaking early warning method and device in vehicle driving. The method comprises the steps of obtaining a historical overtaking accident rate, a historical overtaking rate and a historical vehicle lane changing rate of a target road; according to the current vehicle number of each lane on the target road, the historical overtaking rate and the historical vehicle lane changing rate, predicting the number of target vehicles overtaking by adopting the target lane on the target road; obtaining the number of dangerous vehicles of which the driving distance is smaller than a safe distance on the current target lane; and determining an overtaking risk of the target lane according to the number of the dangerous vehicles, the number of the target vehicles and the historical overtaking accident rate so as to perform early warning according to the overtaking risk. According to the technical scheme, the overtaking risk is determined by combining the actual traffic flow condition on the target road, the accuracy of the overtaking risk is improved, and then the early warning effect is guaranteed.
