The invention relates to an automatic generation method of an active safety system test scene, which belongs to the field of automobile active safety system testing. The method includes the following steps: S1: Calculate and obtain two evaluation indexes to measure the effectiveness of the test scene, namely the complexity index of the scene and the importance index of the influencing factors in the scene; S2: use the two evaluation indexes to guide the combination of improvement The test scenario generation process of the test algorithm; S3: Obtain the test scenario set, and use the evaluation index to evaluate the effectiveness of the generated scenario; S4: Apply the test scenario set to the test and evaluation of the active safety system to be tested. The present invention can make the finally generated test scene set have the advantages of high fault coverage rate by using a small-scale test scene set with the traditional combined test algorithm, and greatly improve the overall effectiveness of the test scene in the set. Thus, the test cost can be effectively reduced and the test efficiency can be significantly improved.
