The invention discloses a power supply circuit of an electronic control unit, a power supply method and a vehicle, relates to the technical field of automobile electronic control, and can improve the reliability of the electronic control unit by adopting a simple circuit structure. Comprising a processor and a plurality of isolation circuits, and each isolation circuit comprises a protection circuit and a first switch circuit which are connected. The processor is used for being connected with a power supply end, the processor is also used for being connected with each functional module in the functional module group, and each functional module is redundant to each other. The first switch circuit in the isolation circuit is used for being connected with one function module in the function module group, and the protection circuit in the isolation circuit is used for being connected with a power supply end. And the protection circuit is used for controlling the connection or disconnection of the corresponding first switching circuit according to the relationship between the current of any functional module and the preset current, thereby ensuring that the power supply end continues to supply power to the processor and other functional modules, and enabling the electronic control unit to work normally.

    本发明公开一种电子控制单元的供电电路、供电方法及车辆,涉及汽车电子控制技术领域,能够采用简单的电路结构提高电子控制单元的可靠性。包括:处理器和多个隔离电路,每个隔离电路包括具有连接关系的保护电路和第一开关电路。处理器用于与电源端连接,处理器还用于连接功能模块组中的各个功能模块,各个功能模块互为冗余。隔离电路中的第一开关电路用于与功能模组中的其中一个功能模块连接,隔离电路中的保护电路用于与电源端连接。保护电路,用于根据任一功能模块的电流与预设电流的关系,控制对应的第一开关电路的导通或关断,从而保证电源端继续向处理器和其他功能模块供电,使电子控制单元正常工作。
