ABSTRACTIn this paper, we describe how vehicle systems and the vehicle motion control are affected by automated driving on public roads. We describe the redundancy needed for a road vehicle to meet certain safety goals. The concept of system safety as well as system solutions to fault tolerant actuation of steering and braking and the associated fault tolerant power supply is described. Notably restriction of the operational domain in case of reduced capability of the driving automation system is discussed. Further we consider path tracking, state estimation of vehicle motion control required for automated driving as well as an example of a minimum risk manoeuver and redundant steering by means of differential braking. The steering by differential braking could offer heterogeneous or dissimilar redundancy that complements the redundancy of described fault tolerant steering systems for driving automation equipped vehicles. Finally, the important topic of verification of driving automation systems is addressed. 相似文献

深海载人潜水器推力器布置与容错性能 总被引:1,自引:0,他引:1
深海载人潜水器能够搭载科学家至深海海底开展精细化取样作业,已成为人类开展深海科学研究和资源勘探开发必不可少的工具。推力器是潜水器机动的主要执行机构,其合理的布置不仅关系潜器操纵性能也直接影响其故障时容错性能。本文首先系统梳理了现役国内外6台深海载人潜水器推力器的布置形式及其参与推力分配的运动模态,基于推力器布置方案分别比较分析了推力器故障情况下的容错控制方案并和优缺点。结果发现用矢量和可回转推力器代替固定推力器可以提高系统的容错控制能力,本文研究对于后续载人潜水器推力器布置和容错控制设计可提供参考借鉴。 相似文献
