The invention relates to the technical field of steering systems, in particular to a safety degradation strategy for failure operation of a master-slave full-redundancy electric power steering system. A safety degradation strategy for failure operation of a master-slave type full-redundancy electric power steering system comprises a main road electric power steering system and an auxiliary road electric power steering system, and the structure of the main road electric power steering system is consistent with that of the auxiliary road electric power steering system. A safety degradation strategy for failure operation of the master-slave type full-redundancy electric power steering system is provided, it is guaranteed that the redundant system can be in a safety degradation mode after multiple times of failure, the steering system can exert the maximum capacity to continue working, and the usability of the redundant steering system is exerted to the maximum extent; the problem that redundant steering systems in other control modes are insufficient in system availability in the aspect of failure operation safety degradation is solved, and the system can exert 100% steering capacity as much as possible.

    本发明涉及转向系统技术领域,具体的说是主从式全冗余电动助力转向系统失效运行的安全降级策略。一种主从式全冗余电动助力转向系统失效运行的安全降级策略,包括主路电动助力转向系统、辅路电动助力转向系统,并且主路电动助力转向系统的结构与辅路电动助力转向系统的结构一致,同现有技术相比,提供一种主从式全冗余电动助力转向系统失效运行的安全降级策略,保证冗余系统发生多次失效都能够进行安全降级模式,且转向系统能够发挥最大能力继续工作,最大限度的发挥冗余转向系统的可用性;优化了其他控制模式的冗余转向系统在失效运行安全降级方面系统可用性不足的问题,使得系统能够尽量发挥100%的转向能力。
