Hybrid electric vehicle energy management system and method based on multi-agent technology

Abstract

The invention discloses a hybrid electric vehicle energy management system and method based on a multi-agent technology. The energy management system comprises a signal collecting agent, a prediction agent, a storage battery agent, an energy management agent and an execution agent. The signal collecting agent collects vehicle condition information and environment information of a vehicle through a data collecting unit and transmits the information to the prediction agent, the prediction agent predicts the running conditions of the vehicle in the next small section of road and transmits the predication information to the energy management agent, the energy management agent calculates the vehicle energy optimal distribution according to the information transmitted by the prediction agent and the information transmitted by the storage battery agent and transmits distribution commands to the execution agent, and finally the execution agent executes a distribution scheme of energy between an engine and a motor. By means of the system, the running conditions of the vehicle in the next small section of road can be predicted in advance, energy management optimal control is conducted, the purpose of optimization is achieved, and the fact that a whole running condition is required in order to conduct overall optimization is avoided.

Description

technical field [0001] The invention relates to the technical field of energy management of a parallel hybrid electric vehicle based on multi-agent technology, in particular to an energy management system and method. Background technique [0002] As a major symbol of modern civilization, automobiles not only bring comfort and convenience to people, but also bring serious environmental pollution and energy consumption. In order to alleviate the two major problems of environmental pollution and energy consumption, all countries are developing energy-saving, New energy vehicles with clean features, and hybrid vehicles are the new energy vehicles that have been mass-produced in the world at present, and will remain the mainstream of new energy vehicle development for a long time to come. [0003] According to the characteristics of the vehicle power system, hybrid electric vehicles are generally divided into series type, parallel type and series-parallel hybrid type. Parallel h...
