高速磁浮车载控制系统预期功能安全验证评估研究

High-Speed Maglev Vehicle Control System SOTIF Verification and Assessment Research

摘要:

车载控制系统是高速磁悬浮列车安全运行的核心组件，安全等级为SIL4。由于其高度自动化、智能化和复杂性，常规的系统试验台测试和功能安全分析验证已经难以适用于该系统复杂失效的分析识别。预期功能安全（SOTIF）是评估和确保复杂系统在预期操作条件下安全性的重要方法，已在智能网联汽车领域成功应用。本文通过开展高速磁悬浮车载控制系统的预期功能安全测试技术研究，构建典型测试场景和测试用例，设计测试验证系统，旨在为车载控制系统批量生产的研究和实践提供参考。

Abstract:

The vehicle control system is the core component for the safe operation of high-speed maglev trains, with a safety level of SIL4. Due to its high degree of automation, intelligence, and complexity, conventional system test bench testing and functional safety analysis verification are no longer suitable for the analysis and identification of complex failures in this system. Safety of the Intended Functionality (SOTIF) is an important method for assessing and ensuring the safety of complex systems under intended operating conditions and has been successfully applied in the field of intelligent connected vehicles. This paper conducts research on the expected functional safety testing technology of high-speed maglev vehicle control systems, constructs typical test scenarios and test cases, and designs a test verification system, aiming to provide references for research and practice in the mass production of vehicle control systems.
