The invention relates to a vehicle queue failure-degradation method and device in an expressway scene, and the method comprises the steps: determining a hazard event ASIL level and a safety target of a vehicle queue system; failure-degradation strategies of different failure forms are generated according to the ASIL levels of the security targets and the hazardous events; when a vehicle is in a preset expressway scene, the vehicle queue system achieves a safety target on the premise of retaining part of functions based on failure-degradation strategies of different failure forms. Therefore, the problems that in the related technology, when the vehicle-mounted hardware of the queue system fails, a safe failure-degradation strategy is lacked, the safety of the vehicle queue system when the vehicle-mounted hardware fails is reduced, safety accidents possibly caused by the failure of the vehicle-mounted hardware are difficult to avoid, and an important basis cannot be provided for industrialization of the vehicle queue system are solved.
本申请涉及一种高速公路场景下车辆队列失效‑降级方法及装置,其中,方法包括:确定出车辆队列系统的危害事件ASIL等级与安全目标;根据安全目标与危害事件ASIL等级生成不同失效形式的失效‑降级策略;在车辆处于预设的高速公路场景时,基于不同失效形式的失效‑降级策略使车辆队列系统在保留部分功能的前提下,达到安全目标。由此,解决了相关技术中,在队列系统车载硬件失效时,缺乏安全的失效‑降级策略,降低了车辆队列系统在出现车载硬件失效时的安全性,难以避免车载硬件失效可能造成的安全事故,无法为车辆队列系统产业化提供重要基础等问题。
