An in-vehicle power supply apparatus includes: a first system; a second system; a first switch; a second switch; an abnormality detection unit; and a switch setting unit configured to set a normal state if the occurrence of a power failure is not detected, and to set the first switch in a fail-safe state in which the first switch is turned off if the occurrence of the power failure is detected, and to set the first switch in the fail-safe state for each of the systems after the first switch is set to the fail-safe state. The abnormality detection unit detects whether any system power failure has occurred, and after the first switch is set to a fail-safe state, the switch setting unit sets each of the switches to a normal state if the occurrence of the system power failure is not detected from both systems.

    一种车载电源设备,包括:第一系统;第二系统;第一开关;第二开关;异常检测单元;以及开关设置单元,被配置为:如果未检测到电源故障的发生,则设置正常状态,并且如果检测到电源故障的发生,则设置第一开关处于关断状态的故障安全状态,并且在第一开关被设置为故障安全状态后,针对系统中的每一个,异常检测单元检测是否已经发生任何系统电源故障,以及在第一开关被设置为故障安全状态后,如果从两个系统中均未检测到系统电源故障的发生,则开关设置单元将开关中的每一个设置为正常状态。
