The invention provides a heavy-duty car lane keeping auxiliary development method and system based on function safety, relates to the technical field of road vehicle function safety, and aims to identify a function fault of a lane keeping auxiliary system; obtaining a safety target and an ASIL level according to the HARA analysis and evaluation model; converting the security target into a security design requirement; the safety design requirements are distributed to elements contained in the lane keeping assistance system; and confirming the functional safety of the lane keeping auxiliary system. According to the invention, an LKA system with functional safety requirements is integrated, so that the safety problem caused by hardware random failure and system failure in traditional product development is solved. In addition, safety risks caused by system failure and hardware random failure can be reduced, and the safety and reliability of the system are improved.

    本发明提供一种基于功能安全的重型汽车车道保持辅助开发方法及系统,涉及道路车辆功能安全技术领域,识别车道保持辅助系统的功能故障;根据HARA分析评估模型得到安全目标和ASIL等级;将安全目标转化为安全设计需求;将安全设计需求分配到车道保持辅助系统所包含的元素中;确认车道保持辅助系统的功能安全。本发明融入功能安全要求的LKA系统,解决传统产品开发中存在的因硬件随机失效和系统失效而带来的安全问题。还可减少因系统失效和硬件随机失效而导致的安全风险,提高系统的安全性和可靠性。
