Systems for Autonomy in Fail-operational Environments (SAFE)

只有成熟和容错的车辆控制系统考虑到任何类型的车辆故障，包括在发生重大计算机系统故障时覆盖自动驾驶软件，才有可能安全部署自动驾驶和远程操作车辆。这些控制系统，也被称为线控驾驶(DBW)系统，还没有被绝大多数汽车制造商商业化，从而严重限制了自动驾驶汽车在所有市场的潜在推出。SAFE(故障操作环境下的自主系统)项目将开发和测试适用于NUIC(无用户负责)和UIC(用户负责)车辆平台的技术，集成能够在广泛的操作设计域(ODDS)内实现SAE Level 4(L4)自主的新型安全系统和子系统。StreetDrone将与两家创新的中小企业一级供应商--底盘和阿尔康合作，整合了关键任务转向和制动子系统的整体故障操作架构。这些都是安全关键的车辆系统，可确保始终对车辆进行横向和纵向控制，即使在发生单点故障时也是如此。为英国国内的CAV行业发展更广泛的供应链的一个关键部分是为所有其他下游系统提供安全可靠的车辆硬件来进行开发和测试；如果没有这一推动因素，通过自动驾驶堆栈进行各种元素工作的组织就无法成功开发和验证他们的产品，更不用说将它们投入商业运营了。这三家创新的英国中小企业将与萨里大学汽车工程中心合作，开发一个可信的解决方案，在多种现实世界背景的模拟中进行测试，并在2024年底之前在赛道上得到验证，并准备好满足预期的4级安全法规。

The safe deployment of autonomous and remotely operated vehicles is only possible with mature and fault-tolerant vehicle control systems where any kind of vehicle failure is taken into consideration, including overriding autonomous driving software in the event of significant computer system failures. These control systems, also called drive-by-wire (DbW) systems, are not yet commercially available to the vast majority of vehicle manufacturers, thereby severely limiting the potential roll-out of autonomous vehicles across all markets.The SAFE (Systems for Autonomy in Fail-Operational Environments) project will develop and test technologies applicable for both NUIC (No User In Charge) and UIC (User in Charge) vehicle platforms integrating novel safety systems and subsystems capable of achieving SAE Level 4 (L4) autonomy within a wide range of Operational Design Domains (ODDs).StreetDrone will collaborate with two innovative SME tier 1 suppliers, Chassis Autonomy and Alcon, bringing together an overall fail-operational architecture integrating mission critical steering and braking sub-systems. These are safety critical vehicle systems that ensure lateral and longitudinal control of the vehicle at all times, even in the event of a single point fault of failure. A key part of developing the wider supply chain for the CAV sector within the UK is providing safe and secure vehicle hardware for all other downstream systems to be developed and tested upon; without this enabler in place, organisations working on various elements through the self-driving stack cannot successfully develop and validate their products let alone place them into commercial operation.Together, these three innovative UK-SMEs will work alongside the Centre of Automotive Engineering at University of Surrey, developing a credible solution, tested in simulations of multiple real world contexts, and proven on the track by end of 2024, and ready for meeting anticipated Level 4 safety regulations.
