The invention relates to a lane changing scene self-adaptive generation method and device for an automatic driving vehicle test, and the method comprises the steps: randomly generating the initial motion states of a tested vehicle and a plurality of interference vehicles based on the pre-established probability distribution of actual lane changing scene state parameters; in response to the fact that the tested vehicle and the interference vehicle reach the motion state, performing a lane changing test on the tested vehicle, acquiring the real-time motion state in the test process, and updating the lane changing progress index of the tested vehicle; in response to the update of the lane changing progress index, updating the target state of the interference vehicle based on the lane changing progress index and the current planning strategy, and controlling the interference vehicle to reach the updated target state; and responding to a lane changing test result of the tested vehicle, adaptively optimizing the planning strategy, and realizing adaptive generation of a lane changing scene. Compared with the prior art, the method has the advantages that the relevance between the tested vehicle and the interference vehicle behavior is fully considered, and the testing efficiency of the boundary effect of the tested vehicle is improved.
