Abstract

The invention discloses a power management method for a low-voltage system. The low-voltage system includes a plurality of electrical equipment; the current available power of the low-voltage system is obtained; the current used power of each electrical equipment in the low-voltage system and the required power corresponding to each electrical equipment are obtained; Determine whether the current available power is greater than or equal to zero, and determine whether the sum of the currently used power of each electrical equipment is greater than the sum of the required power of each electrical equipment; and, the used power of the first target electrical device is increased, and the first target electrical device is an electrical device whose priority is greater than the preset priority and whose required power is greater than the currently used power. The present invention distributes the available power of the low-voltage system of the vehicle reasonably and dynamically through the signal interaction of the electrical system. Compared with the traditional shutdown of all designated loads or the request to increase the output power of the generator, the distribution of the invention is more intelligent, fast and accurate.

Description

technical field [0001] The present invention relates to the technical field of vehicle low-voltage system power management, in particular to a low-voltage system power management method, device and vehicle. Background technique [0002] With the rapid development of automotive electronic and electrical technology, the electrical functions are increasing and complex, and the requirements for vehicle comfort, intelligence, safety and reliability have increased, resulting in more and more high-power electrical loads on vehicles, such as front and rear blowers, air door motors. , steering wheel heating, seat ventilation, seat heating, etc., so that the power consumption and power of the car load increase accordingly. It is critical to provide enough power output and power output to keep the electrical system working properly. At present, domestic automobile manufacturers are facing the important issue of how to improve the power efficiency of the whole vehicle. When the speed ...
