The invention discloses a redundant power-assisted steering system, a control method thereof and a vehicle, and belongs to the technical field of vehicles. The redundant power-assisted steering system disclosed by the invention comprises a hydraulic power-assisted steering assembly used for providing relatively large main steering assistance in an automatic driving mode; a first electric power steering EPS assembly which is used for providing relatively small first supplementary steering assistance in an automatic driving mode; a second electric power steering EPS assembly which is used for outputting second supplementary steering assistance used for replacing the first supplementary steering assistance under the condition that the first electric power steering EPS assembly fails, wherein the first electric power steering EPS assembly and the second electric power steering EPS assembly are further configured to be capable of jointly outputting redundant steering assistance used for at least partially replacing the main steering assistance when the hydraulic power steering assembly fails in an automatic driving mode. The redundant power-assisted steering system is good in safety in an automatic driving mode.

    本发明公开一种冗余助力转向系统及其控制方法、以及车辆,属于车辆技术领域。本发明公开的冗余助力转向系统包括:液压助力转向总成,其用于在自动驾驶模式下提供相对较大的主转向助力;第一电动助力转向EPS总成,其用于在自动驾驶模式下提供相对较小的第一补充转向助力;以及第二电动助力转向EPS总成,其用于在所述第一电动助力转向EPS总成失效的情况下输出用于替代所述第一补充转向助力的第二补充转向助力;其中,所述第一电动助力转向EPS总成和所述第二电动助力转向EPS总成还被配置为,在自动驾驶模式下所述液压助力转向总成失效时能够共同输出用于至少部分地替代所述主转向助力的冗余转向助力。本发明的冗余助力转向系统在自动驾驶模式下安全性好。
