Distributed automobile electric energy regulating method

Abstract

The invention relates to a distributed automobile electric energy regulating method and belongs to the technical field of automobile electric energy control. Static electric energy is regulated: when a vehicle is in a standing state, controllers meeting the conditions first enter a primary sleep state; if a message is not detected during a certain time, the controllers having entered the primary sleep state are ordered to enter a secondary sleep state, a storage battery closes power supply of related loads according to different states of the current vehicle and makes related control units enter a sleep mode, a quiescent current is lowered, and the standing time is improved. Dynamic electric energy is regulated when the vehicle runs, and the state of the storage battery is detected; if it is detected that the storage battery is in a negative balance state, real-time state data of the vehicle are collected and compared with a set threshold, current-using equipment does not meet the set threshold is shut down, and a generator is made to continuously supply power to the storage battery. Through the mode, negative balance does not occur in electric energy consumed by an electric energy output device and electric appliance loads, and it is guaranteed that feed does not occur in the storage battery.

Description

technical field [0001] The invention belongs to the technical field of automobile electric energy control, and in particular relates to a distributed automobile electric energy control method. Background technique [0002] In order to meet the driver's increasingly higher requirements for car safety and comfort, modern cars have added many humanized functions such as: lane departure warning, night vision system, collision recognition, lane change blind spot warning, moving object / pedestrian detection Early warning, panoramic camera, adaptive cruise, seat ventilation, massage, memory, multi-zone air conditioning, knee airbags, automatic parking system, etc. Realizing the above functions requires adding a lot of electrical loads such as sensors, controllers and high-power actuators on the basis of the electrical system of the vehicle. Generally, only batteries and generators in the vehicle can provide limited power output. For the system to work normally, it is necessary to d...

Problems solved by technology

The advantage of this method is that the degree of intelligence is relatively high, complex control strategies can be realized, and because it is a separate component, it is convenient for the design of the vehicle electrical integration scheme, but this method has certain limitations, that is, the cost is high. It can only be used in high-end cars. At the same time, due to the characteristics of centralized control of functions, the internal software of the control unit is very complicated. When it fails, it will have a great impact on the functions of the electrical system of the vehicle, and the risk is high.
