RESEARCH ON THE STABILITY PERFORMANCES OF THE VEHICLE DYNAMICS EQUIVALENT SYSTEM BASED ON THE UNSTEADY CON-STRAINTS

Abstract

Set up the vehicle stability control dynamics system based on the unsteady constraints. Establish the vehicle stability control dynamics equivalent system based on the unsteady constraints using the artificial neural network and the ESP control principle based on the integrated control of brake and drive. Based on the Matlab/Simulink establish the stability performances simulation test system of the vehicle dynamics equivalent system for the Chery A3 car. Using the simulation model, respectively simulate the stability performances of the vehicle dynamics equivalent system and the independent vehicle system on steadystate conditions of neutral steering, under steering and over steering. The study results indicate that the stability performances of the vehicle dynamics equivalent system based on the unsteady constraints and the independent vehicle system show remarkable consistency, it will provide a theoretical basis and technical support for establishing the safe and efficient test platform for vehicle stability control based on the unsteady constraints vehicle stability control dynamics equivalent system to research the vehicle stability control performances.
