Vehicle Power Steering System Based on Human-simulated Intelligent Control

Thetraditional power steering by fluid drive has many defects such as producing extra steering, oil pollution and consuming excessive resources. Electric Power Steering is servo-control system which can supply power by motor which is controlledby micro-processor-embeded controller. So the application of Electric Power Steering Systemin vehicleis the developing direction. Based on the deep research of power steering system for vehicle, aiming at the complexity and uncertaintyof road and the difference for driver operating habit, the paper presents a sort of new algorithmthat is stronger in robustness, better in adaptability. The algorithmhas been applied in the physical vehicle steering system. The engineering practice shows that the algorithmtakes care of both control effect and person's feeling, and it is satisfactory to control effect.
