The invention discloses a dual-power redundant backup architecture and a control method, the architecture comprises a power distributor, an HNS1 line and an HNS2 line, a main line of the HNS1 line and a main line of the HNS2 line are respectively connected in series with a power isolator and then are connected with the power distributor, and a BFD module is arranged among a load, a main battery and the power isolator HNS1 on the HNS1 line; a BFD module is arranged among the load, the auxiliary battery and the power supply isolator HNS2 on the HNS2 line. A dual-power-supply redundancy design scheme is adopted, it is guaranteed that function degradation can be achieved when the whole vehicle breaks down, and enough taking-over time is provided for a driver.
本发明公开了一种双电源冗余备份架构及控制方法,包括配电器、HNS1线路、HNS2线路,所述HNS1线路的主线、所述HNS2线路的主线分别串联电源隔离器之后与所述配电器连接,所述HNS1线路上的负载、主电池、电源隔离器HNS1之间设置有BFD模块;所述HNS2线路上的负载、副电池、电源隔离器HNS2之间设置有BFD模块。本发明采用双电源冗余设计方案,保证在整车发生故障时能够实现功能降级,并提供足够的驾驶员接管时间。
