Problems solved by technology
At present, most manufacturers use directly obtained raw data for data labeling, scene generation and import, and there is no reasonable and effective method to systematically summarize and classify simulated driving scenarios, making it difficult to evaluate the comprehensiveness of test cases in simulated scenarios. Therefore, it is impossible to evaluate the effectiveness of the simulation test from the perspective of the simulation test scenario

The invention provides a method for converting original data into a logic scene and finally generating a specific test case in a simulation test, which comprises the following steps of: S1, inputtingthe acquired original scene data with a reasonable data label into a system; s2, judging whether a state change exists or not; s3, recording the initial position of the target object in the scene; s4,recording the driving behavior of the started vehicle as 'driving'; s5, judging the driving behavior of the vehicle; s6, cutting and concluding the data recorded in the step S5 into a logic scene combination; s7, inputting the cut and concluded data into a compiler to generate a scene file in an OpenSCENARIO2.0 format; and S8, inputting the OpenSCENARIO2.0 format file into a compiler, and automatically generating a simulation test case. According to the method for generating the simulation test case in the simulation test, targets and elements in a scene can be modularized by analyzing and concluding original scene data, a data collector and a user can conclude and classify various types of scenes more quickly, and unified and quick conversion is realized when simulation software is imported.
Description
technical field [0001] The invention belongs to the field of intelligent networked vehicles, and in particular relates to a method for generating simulation test cases in simulation testing. Background technique [0002] Simulation verification is an indispensable part of the field of intelligent networked vehicles, and the quality of simulation test scenarios determines the comprehensiveness and effectiveness of simulation verification. At present, most manufacturers use directly obtained raw data for data labeling, scene generation and import, and there is no reasonable and effective method to systematically summarize and classify simulated driving scenarios, making it difficult to evaluate the comprehensiveness of test cases in simulated scenarios. Therefore, it is impossible to evaluate the effectiveness of the simulation test from the perspective of the simulation test scenario. Therefore, it is necessary to create a systematic and comprehensive classification method f...
