The invention belongs to the technical field of intelligent automobiles, and particularly relates to an intelligent automobile key scene generation method based on a personalized interactive car-following model. Comprising the following steps of 1, selecting a natural driving data set and performing preprocessing; 2, constructing a personalized interactive car-following model; step 3, generating a key scene; 4, evaluating the key scene; according to the method, the personalized car-following model with high real interaction characteristics is constructed, on this basis, through multi-element weight distribution of the model, interaction characteristics between vehicles are diversified, the scene parameter coverage range is expanded, the scene generation difficulty can be reduced, meanwhile, key scenes with high coverage, high reasonability and high diversity can be generated, and the method is suitable for large-scale popularization and application. The problems of low scene coverage, poor scene rationality, single scene type and the like existing in key scene generation based on natural driving data in a current method are solved.
