Abstract

The steer by wire (SBW) system use electric wires to transmit angle of steering wheel between steering wheel and front wheel. The influence factors of ideal transmission ratio in SBW system were studied in this paper. Ideal transmission ratio model of SBW system was established by applying fuzzy control theory and this model has relation with vehicle speed and steering angle of steering wheel in the case of turning, therefore this model can reflect the relation between transmissions ratio of SBW system and each affect factor more reasonable. The front angle distinguish controller resolved the destabilization problem of SBW system in the condition of large steering angle in high speed. The system error of front angle distinguish controller is less than 2×10^-3 and it has better approach learning capability.
