AI Technical Summary

Technical Problem

In the centralized architecture of vehicles, the power supply mode of edge nodes is constant voltage and constant power or fixed duty cycle, resulting in low utilization of vehicle power supply.

Method used

The central controller receives real-time power supply data from edge nodes, determines the load power supply requirements that match the real-time vehicle scenario, generates power supply adjustment commands, and sends them to edge nodes to achieve dynamic adjustment of power supply levels, including sleep, standby, normal, and heavy load levels, thereby optimizing the power supply system.

Benefits of technology

It improves the utilization rate of vehicle power supply, ensures the power supply quality of necessary loads under different operating conditions, and avoids high power consumption output of unnecessary loads, thereby improving the overall energy efficiency and safety of the power supply system.

Abstract

The application relates to an edge node power supply control method, a central controller, an edge node and a vehicle. The method comprises the following steps: receiving real-time power supply data collected by a target edge node; the target edge node is any edge node in a vehicle-mounted central centralized architecture, and the real-time power supply data is real-time power supply data of each load corresponding to the target edge node; determining a load power supply demand matched with a vehicle-mounted real-time scene; generating a power supply adjustment instruction corresponding to the target edge node based on the load power supply demand and the real-time power supply data, and sending the power supply adjustment instruction to the target edge node; the power supply adjustment instruction is used for instructing the target edge node to perform a power supply adjustment operation on each load. The utilization rate of the vehicle-mounted power supply is improved.
