The invention discloses a dangerous lane changing scene generalization generation method and system for an automatic driving test, and the method comprises the steps: designing a generative adversarial model for the generation of an emergency lane changing track, employing the emergency lane changing track in a public automatic driving data set as original data, inputting the original data into the model, and generating the emergency lane changing track; and transverse and longitudinal kinematics constraints of the automatic driving vehicle are decoupled, and a safety constraint model in the lane changing process is established, so that the initial state of the tested automatic driving vehicle corresponding to each generated emergency lane changing track is calculated, and an automatic driving test dangerous lane changing scene is generated. According to the method, the emergency lane changing track conforming to the real lane changing characteristics can be generated, and the problems of how to generate the emergency lane changing tracks of different cut-in angles conforming to the human driving vehicle characteristics and how to construct the theoretically avoided risk critical test scene by using the background vehicle lane changing tracks of different risks are solved; an automatic driving test dangerous lane changing scene can be effectively generated.
