The invention discloses a safety redundancy architecture of an automatic driving vehicle, which comprises a task layer and a safety layer, the task layer and the safety layer respectively receive input and output through the safety layer, the task layer and the safety layer can ensure the safety of the automatic driving vehicle and simultaneously realize required tasks, and the safety and the reliability of the automatic driving vehicle are improved; functions are limited in the security layer through an algorithm instead of limiting the redundant architecture, constraints are reduced along with extension of the security algorithm, deterministic guarantee for false alarms is kept, dependence on obstacle attributes is eliminated, the part can be integrated into the redundant architecture, hardware is not added, and the cost is low; the security layer simplifies the task layer test work and cost, unlike expensive task layer redundancy, it can secure a single task layer and protect the task layer through a highly redundant security layer running on a low cost embedded platform.
本发明公开一种自动驾驶车辆的安全冗余架构,包括任务层和安全层,任务层与安全层分别接收输入,并通过安全层进行输出,任务层和安全层能够在保证自动驾驶车辆安全的同时实现其所需任务,提高自动驾驶车辆的安全性和可靠性;在安全层中通过算法进行功能的限制,而非对冗余架构的限制,随着安全算法的扩展,减少约束,同时保持针对误报的确定性保证,消除对障碍物属性的依赖,而此部分能够集成到冗余架构中,并不增加硬件,成本较低;安全层简化了任务层测试工作和成本,不同于昂贵的任务层冗余,它可以使单个任务层变得安全,并通过在低成本嵌入式平台上运行的高度冗余安全层对任务层进行保护。
