Power-on and power-off control method of all-in-one controller

According to the power-on and power-off control method of the all-in-one controller, the all-in-one controller comprises a high-voltage distribution box, a motor controller, a direct-current converter, an oil pump controller and an air pump controller, and the high-voltage distribution box, the motor controller, the direct-current converter, the oil pump controller and the air pump controller are all in signal connection with a power CAN bus; the control method comprises the following steps: initializing after the high-voltage distribution box detects a power supply awakening signal, and awakening other components in the all-in-one controller after the initialization of the high-voltage distribution box is completed; the high-voltage distribution box judges whether the current rotating speed of the motor is zero or not after detecting that the power supply wake-up signal is disconnected, if the rotating speed of the motor is not zero, the high-voltage distribution box continues to send a wake-up signal to oth
