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;通过开展高速磁悬浮车载控制系统的预期功能安全验证评估系统研究,构建典型预期功能安全场景和场景测试用例,设计验证评估系统,旨在为车载控制系统批量生产提供技术支撑,为提升高速磁悬浮列车的安全提供重要的技术保障。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,it is difficult for conventional system testing on the test bench and functional safety analysis verification to analyze and identify complex failures.safety of the intended functionality(SOTIF)is an important method for assessing and ensuring the safety of complex systems under expected operating conditions,which is successfully applied in intelligent connected vehicles.By studying the expected functional safety verification and assessment of high-speed maglev on-board control system,the typical expected function safety scenarios and scenario testing cases are constructed,and the verification and assessment system is designed,which provides technical support for mass production of vehicle control systems and important technological guarantee for enhancing the safety of high-speed maglev trains.
