The invention provides a domain controller power supply circuit and a vehicle, and the circuit comprises a control unit which is provided with a plurality of output ends, and the output ends of the control unit are used for outputting control signals; each switch unit is provided with a first end and a second end, the first end of one switch unit is electrically connected with one output end of the control unit, and the control signal is used for controlling the switch units to be switched off or switched on; and the plurality of power supply units are provided with input ends, the input end of one power supply unit is electrically connected with the second end of one switch unit, the control unit is disconnected with the power supply units under the condition that the switch units are disconnected, and the control unit is connected with the power supply units under the condition that the switch units are closed. According to the circuit, through a plurality of output ends of a control unit, when a domain controller breaks down, power supply units of a plurality of domain controllers are controlled to be turned off at the same time. The problem that an existing domain controller power supply management system is single and cannot control various controller power supplies at the same time is solved.
本申请提供了一种域控制器电源电路和车辆,该电路包括:控制单元,具有多个输出端,控制单元的输出端用于输出控制信号;多个开关单元,各开关单元具有第一端和第二端,一个开关单元的第一端与控制单元的一个输出端电连接,控制信号用于控制开关单元断开或者闭合;多个电源单元,具有输入端,一个电源单元的输入端与一个开关单元的第二端电连接,在开关单元断开的情况下,控制单元与电源单元之间断开连接,在开关单元闭合的情况下,控制单元与电源单元之间连接。该电路通过一个控制单元的多个输出端,在域控制器发生故障时,同时控制多个域控制器的电源单元的关断。解决了现有的域控制器电源管理系统比较单一,无法同时控制多种控制器电源的问题。
