The invention discloses a high-voltage loop control system, a high-voltage loop control method, a circuit board and a vehicle. The system comprises a high-voltage loop main positive and main negative relay, a first driving chip, a second driving chip, a PMIC and an MCU. Four GPIO (General Purpose Input/Output) ports of the MCU are respectively connected with two driving input ports of the first driving chip and the second driving chip; the driving output ports of the first driving chip and the second driving chip are respectively connected with the positive electrode and the negative electrode of a main positive relay and a main negative relay in the high-voltage loop main positive and main negative relays; two fault indication protocol ports of the MCU are connected with two MCU monitor ports of the PMIC; and two functional safety output ports of the PMIC are connected with a first driving input port and a second driving input port of the first driving chip through four switching circuits. According to the technical scheme provided by the embodiment of the invention, the security risk caused by random hardware failure and network attack of the electronic device can be effectively reduced.
