Intelligent steering control method for four-wheel hub motor electric vehicle

Abstract

The invention discloses a four-wheel hub motor electric automobile intelligent steering control method. Drivers are classified by adopting a fuzzy C-mean clustering method; an RBF neural network is respectively established for the corresponding three driver types according to the driver types; expected transverse swing angle speed is determined correspondingly through corresponding types of the RBF neural networks according to different types of drivers; then a four-wheel hub motor electric automobile intelligent steering control model is established by utilizing fuzzy control; deviation of the expected transverse swing angle speed and actual transverse swing angle speed, deviation change rate and additional transverse swing moment are respectively converted into quantization levels in a fuzzy domain of discourse; and the fuzzy control model outputs the additional transverse swing moment, and the four wheels of an electric automobile are respectively controlled to perform steering according to the outputted additional transverse swing moment. The four-wheel hub motor electric automobile intelligent steering control method has characteristics of being high in automobile control safety and stability and can realize the function of intelligent steering of the automobile for people so as to enhance steering comfortableness of the drivers.

Description

technical field [0001] The invention relates to the technology in the field of automobile intelligent control, in particular to an intelligent steering control method for an electric vehicle with four-wheel hub motors. Background technique [0002] In today's society, cars have become an indispensable means of transportation in people's lives. With the development of science and technology and the improvement of people's living standards, people have higher and higher requirements for cars. Cars are no longer just ordinary means of transportation, but have risen to become a culture and a symbol. The importance of cars is self-evident. Metaphor. Safety, comfort, energy saving, and environmental protection are the direction and eternal theme of automobile development, especially in today's world where traffic accidents are increasing, energy is increasingly scarce, and the environment is deteriorating. Electronics, intelligence, electrification, and regeneration are effectiv...
