Outline
In order to ensure the repeatability of simulation tests and reliability of test results, a simulation testing platform is built using Unity and Unreal Engine based on a systematic analysis of the definition and potential causes of performance consistency issues in autonomous driving simulation software, and static and dynamic scenarios are built at the same time. The study also involves the design of test cases, data processing scripts, automated testing scripts and the overall experimental process. Test results based on Unity and Unreal Engine simulation test platform are quantified through the inconsistency deviation. Influenced by various factors related to the simulation system’s software and hardware, experimental results reveal significant inconsistencies in multiple tests, with the maximum deviation reaching 15%. To address the identified deviation, this paper proposes several optimization strategies, including process optimization and power mode optimization, which are validated to reduce the deviation by more than 40%, thereby enhancing the reliability and consistency of simulation tests.
