Energy-saving control method and device for vehicle low-voltage system and vehicle cloud cooperative system

The invention relates to an energy-saving control method and device for a vehicle low-voltage system and a vehicle cloud cooperative system. The method comprises the following steps: acquiring burying point data and a low-voltage system architecture of a vehicle; defining a scene mode based on the burying point data; the scene mode comprises a general scene mode and a personalized scene mode; determining a preset workload list of the scene mode according to the low-voltage system architecture; acquiring a power supply mode, a vehicle mode and a user demand signal of the vehicle; determining a target scene mode according to the user demand signal; the target scene mode is one of the general scene mode and the personalized scene mode; obtaining a target workload list according to the target scene mode; and controlling the working state of a target workload according to the power supply mode, the vehicle mode and the target workload list. By adopting the method, the power loss of a low-voltage system of the vehi
