Abstract

The invention aims to provide the expert control system of the hybrid electric vehicle and the control method of the expert control system, and aims to optimize a control strategy, automatically adjust a working mode, reasonably distribute power, enable the matching of an engine and a motor to be in an optimal working area, reduce oil consumption and pollution emission and improve the comfort of passengers. The system comprises an expert control subsystem, and the expert control subsystem is connected with a data acquisition subsystem, a power and coupling transmission subsystem and a control execution subsystem through a field bus. The data acquisition subsystem is used for acquiring operation of a driver and real-time dynamic information of automobile driving; the expert control subsystem is used for obtaining a control decision according to operation of a driver, real-time dynamic information of automobile driving and a control method and sending the control decision to the control execution subsystem; and the control execution subsystem controls the power and coupling transmission subsystem to switch the driving mode of the automobile according to the control decision.

Description

technical field [0001] The invention belongs to the technical field related to hybrid electric vehicle control, and in particular relates to an expert control system and a control method for a hybrid electric vehicle. Background technique [0002] Facing the dual pressure of environmental pollution and energy shortage, new energy vehicles have become a hot research topic at home and abroad. Gasoline-electric hybrid vehicles not only have the characteristics of internal combustion locomotives, but also have the advantages of electric vehicles. The drive system of a gasoline-electric hybrid vehicle is composed of a traditional internal combustion engine and an electric motor, and the system structure is divided into series, parallel and hybrid. [0003] When the vehicle is running, the driving mode is determined by the driver's intention and the actual running state of the vehicle. The driving mode includes pure gasoline engine drive, pure electric drive, hybrid drive, and re...
