Abstract :
Research was conducted on vehicle stability control algorithm for four wheel drive (4WD) mini electric vehicle (EV) basing on vehicle dynamics model. The whole vehicle model with eight degrees of freedom was constructed using graphics modeling technology and S-function in MATLAB/Simulink, which includes 4 wheel rotation speeds, front wheel steering angle, vehicle lateral speed, longitudinal motion, and yawing speed. A multi-input and multi-output(MIMO) vehicle stability control (VSC) fuzzy logic controller(FLC) was designed to meet non-linear and transient characteristics of vehicle motion. And simulation analysis was conducted to prove VSC PLC with side-slip angle and yawing speed as input and PWM duty as output.
