  "textContent": "A control method of an electromagnetic clutch in a hybrid power system and a hybrid power system are disclosed. Besides the electromagnetic clutch, the hybrid power system further comprises an engine or motor, a motor, an electromagnetic clutch controller and a power supply system. The power supply system comprises: a low-voltage battery, a standby power supply system and a switching circuit. The electromagnetic clutch is used to control connection of the motor. The control method comprises: monitoring whether a voltage of the low-voltage battery is lower than a target value, and judging whether the low-voltage battery fails; using the switching circuit to switch to the standby power supply system to supply power to the electromagnetic clutch and the electromagnetic clutch controller; using the electromagnetic clutch controller to judge an engaged or disengaged state of the electromagnetic clutch; and further controlling the electromagnetic clutch according to the engaged or disengaged state. When the low-voltage battery power supply fails, the switching circuit switches to the standby power supply system to supply power, thereby ensuring that the electromagnetic clutch is in a reasonable state and make the hybrid power system more safe and reliable.",
