摘要： 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.

摘要： A dual-motor drive assembly and a vehicle are disclosed. The dual-motor drive assembly comprises a first motor and a second motor arranged coaxially, a first gear transmission, a second gear transmission, and one or more idle gear pairs (42, 52). The first gear transmission is driven by the first motor, and the second gear transmission is driven by the second motor. The idle gear pairs (42, 52) are respectively arranged in the first gear transmission and the second gear transmission and are configured to increase a distance between an output shaft of the first motor (15) and an end shaft of the first gear transmission. By adding the idle gears, the center distance between the input shaft and the output shaft in the assembly can be adjusted more flexibly by adjusting the size of the idle gears to realize a larger center distance and make full use of the structural space brought by the larger center distance to install other components; moreover, it can be adjusted according to the space layout requirements and performance requirements of different users.
