Abstract

The invention relates to an automatic generation method for the active safety system test scene of an automobile, and belongs to the field of the active safety system test of the automobile. The method comprises the following steps that: S1: calculating two evaluation indexes for measuring the effectiveness of a test scene, wherein the two evaluation indexes are a scene complexity index and the importance degree index of an influence factor in the scene; S2: using two evaluation indexes for guiding the test scene generation process of an improved combined test algorithm; S3: obtaining a test scene set, and utilizing the evaluation indexes to evaluate the effectiveness of a generated scene; and S4: using the test scene set to the testing and the evaluation of the active safety system to betested. By use of the method, the integral effectiveness of the test scene in the set can be greatly improved while the finally generated test scene set has the advantages that a traditional combinedtest algorithm utilizes a small-scale test scene set to realize a high fault coverage rate, so that test cost is effectively lowered, and test efficiency is obviously improved.
