Abstract: A hybrid power system comprises an engine, a motor, an electromagnetic clutch, 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. A 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.

Abstract: A differential system includes a differential and a differential disconnect mechanism. The differential includes an outer differential housing and an inner differential housing. The differential disconnect mechanism includes a disconnect clutch, first end face teeth and second end face teeth. The first end face teeth are disposed between the outer differential housing and the inner differential housing and are movably connected with the outer differential housing so that the first end face teeth can move axially and rotate synchronously relative to the outer differential housing. The second end face teeth are fixedly connected with the inner differential housing. The disconnect clutch is connected with the first end face teeth, and is configured to drive the first end face teeth to move axially relative to the second end face teeth.
