The invention relates to a power-assisted steering system of an electric mining truck and the electric mining truck. The power-assisted steering system comprises a first power-assisted steering unit and a second power-assisted steering unit, a first control device is arranged in the first power-assisted steering unit, and the first control device is electrically connected with the second power-assisted steering unit; the first control device is used for controlling the first power-assisted steering unit to provide power-assisted steering for the electric mining truck when it is detected that the second power-assisted steering unit stops providing power-assisted steering for the electric mining truck. On the basis, when the second power-assisted steering unit stops providing the power-assisted steering for the electric mining truck due to the fault, the first power-assisted steering unit can replace the second power-assisted steering unit in time to provide the power-assisted steering for the electric mining truck, so that the power-assisted steering output by the power-assisted steering system is more stable; and safety accidents caused by loss of power-assisted steering of the electric mining truck can be avoided.

    本发明涉及一种电动矿用卡车的转向助力系统及电动矿用卡车,该转向助力系统包括:第一转向助力单元和第二转向助力单元;所述第一转向助力单元中设置有第一控制装置,所述第一控制装置与所述第二转向助力单元电连接;所述第一控制装置用于在检测到所述第二转向助力单元停止向电动矿用卡车提供转向助力时,控制所述第一转向助力单元向电动矿用卡车提供转向助力。基于此,由于在第二转向助力单元因故障原因停止向电动矿用卡车提供转向助力时,第一转向助力单元能够及时代替第二转向助力单元,向电动矿用卡车提供转向助力,使得本发明的转向助力系统输出的转向助力更稳定,有利于避免电动矿用卡车因失去转向助力而发生安全事故的情况发生。
