The invention discloses a driving risk intelligent early warning method, system and device considering vehicle interaction. The method comprises the following steps: establishing a driving risk assessment model; historical vehicle trajectory data are collected, key features are extracted for clustering, clustering results are divided into risk levels, and early warning thresholds corresponding to the risk levels are determined; real-time vehicle motion state information of the vehicle and the front vehicle is obtained in real time, so that a real-time risk level is obtained; and issuing corresponding preset early warning information to the driver according to the real-time risk level. The driving risk assessment model is utilized to accurately assess the potential collision risk of the vehicle in real time, a large amount of historical vehicle trajectory data is combined, the early warning threshold values of different risk levels are determined, effective early warning suggestions are provided in different risk scenes, and a driver is better assisted to cope with the potential risk. According to the method, the accuracy and the real-time performance of risk assessment can be improved, the driving safety in a complex traffic environment is remarkably improved, and the accident risk is reduced.
