A Hybrid Electric Vehicle Powertrain Intelligent Control System

Abstract

The invention discloses an intelligent control system of a hybrid electric vehicle power assembly, and belongs to the technical field of hybrid electric vehicles. An intelligent body of a power assembly component comprises an engine intelligent body, a motor intelligent body, a storage battery intelligent body, a transmission intelligent body and a system intelligent body. The intelligent bodies of main components of the hybrid electric vehicle power assembly monitor real-time state information of an engine, a motor, a storage battery and a transmission and interacts the information to the system intelligent body; the system intelligent body receives the state information of the engine, the motor, the storage battery and the transmission, intellectually selects a working mode matched with the present vehicle state and the present traveling road condition, generates an engine power task, a motor power task and a storage battery electric quantity task under guide of a control strategy corresponding to the selected working mode and meanwhile interacts the tasks to the intelligent body of each component, and the tasks are carried out by each component of the power assembly after being regulated by each intelligent body. The intelligent control system of the hybrid electric vehicle power assembly is high in intelligentization degree and improves control efficiency.

Description

technical field [0001] The invention relates to the technical field of hybrid electric vehicle power assembly, and more specifically relates to an intelligent control system for hybrid electric vehicle power assembly. Background technique [0002] With the increasingly serious problems of energy shortage and environmental pollution, safety, energy saving and environmental protection have become the development direction of future automobile technology, and hybrid electric vehicles have become the first choice for research because of their energy saving and environmental protection. Compared with traditional vehicles, hybrid vehicles can save fuel consumption, reduce emissions, and take into account the advantages of internal combustion engine vehicles and electric vehicles. An intelligent control method will have significant social and economic benefits. [0003] Common powertrain control methods for hybrid electric vehicles are generally based on the universal characterist...

Problems solved by technology

[0005] The technical problem solved by the present invention is to provide an intelligent control system for the powertrain of a hybrid electric vehicle, which can intelligently select the working mode of the vehicle and the control strategy adapted to the mode according to the driving conditions of the vehicle, and solve the problem of traditional control methods. For the different working modes of the powertrain of hybrid electric vehicles, the single control strategy cannot make all the components of the powertrain work in the best state, resulting in unnecessary waste of energy provided by the engine and battery, and the traditional control system and control method Centralized data processing and centralized execution of control results bring about low data processing efficiency
