Multi-body Dynamical Modeling and Co-simulation of Active front Steering Vehicle
With the help of ADAMS,a dynamical model of the active front steering system with double planetary gear mechanism and the whole vehicle model were built.Based on fuzzy control theory,the fuzzy control strategy for the vehicle with an active front steering system was put forward,the proposed AFS took the side slip angle of mass centre and yaw rate of the vehicle as fuzzy control rule input,and the output was the motor angle in the active front steering system.The co-simulation of the control system and the vehicle model was realized through the data exchanging between ADAMS and Matlab,then the dynamic response of the vehicle with active front steering under typical driving condition was simulated.The research results showed that the method of fuzzy control can control the yaw rate and the side-slip angle of mass centre,therefore lateral stability of vehicle is further improved.
