Systems for Autonomy in Fail-operational Environments (SAFE)

只有成熟的容错车辆控制系统才能安全部署自动驾驶和远程操作车辆，其中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。这些控制系统，也称为线控驱动（DbW）系统，还没有商业上可用于绝大多数车辆制造商，从而严重限制了自动驾驶汽车在所有市场的推广。（故障运行环境下的自主系统）项目将开发和测试适用于NUIC和（无用户负责）和UIC（用户负责）车辆平台集成了新型安全系统和子系统，能够在广泛的操作设计领域（ODD）内实现SAE 4级（L4）自主性。StreetDrone将与两家创新的SME 1级供应商合作，底盘自动化和Alcon，将集成使命关键转向和制动子系统的整体故障操作架构结合在一起。这些都是安全关键的车辆系统，确保车辆的横向和纵向控制在任何时候，即使在单点故障的故障。在英国为CAV部门开发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。如果没有这一推动因素，通过自动驾驶堆栈处理各种元素的组织无法成功开发和验证他们的产品，更不用说将其投入商业运营。总之，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，开发可靠的解决方案，在多个真实的世界环境的模拟中进行测试，并在2024年底前在赛道上进行验证，并准备满足预期的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.
