The invention discloses an ECU switching power supply circuit, a whole vehicle control system and a vehicle, and relates to the technical field of ECUs, the ECU switching power supply circuit comprises a relay and an ECU circuit board, the first end of the relay is connected with a power supply, and the ECU circuit board is provided with a first connecting end, a ninth connecting end, a power supply circuit and a micro-control unit. The first connecting end is connected with the second end of the relay and the power supply circuit, and the ninth connecting end is connected with the I/O interface of the micro-control unit and the control end of the relay. The relay is connected with the power supply circuit on the ECU circuit board in an external connection mode, the problem that packaging of a high-power MOSFET needs to occupy a large space of the ECU circuit board is solved, the size of the ECU circuit board is reduced, and meanwhile the stability and reliability of the switching power supply are greatly improved.

    本发明公开了一种ECU开关电源电路、整车控制系统及车辆,涉及ECU技术领域,所述ECU开关电源电路包括:继电器和ECU电路板,所述继电器的第一端与电源连接,所述ECU电路板上设有第一连接端、第九连接端、供电电路和微控制单元,所述第一连接端与所述继电器的第二端和所述供电电路连接,所述第九连接端与所述微控制单元的I/O接口和所述继电器的控制端连接。本发明的继电器通过外接的方式与ECU电路板上的供电电路连接,既解决了封装大功率的MOSFET需要占据较大ECU电路板空间的问题,缩小ECU电路板尺寸,同时极大地提高了开关电源的稳定性和可靠性。
