Simulation Analysis of Heavy Truck EPS System

A fuzzy control based on particle swarm optimization of heavy truck EPS system control strategy is proposed, on the basis of vehicle EPS system overall design, combined with the driver steering subjective feeling and the sense of road requirements designed assistance characteristics curve, steering system model, 7 degrees of freedom vehicle dynamics model. The simulation experimental results show that compared with the conventional fuzzy control, this method can improve the whole dynamic response of heavy truck EPS system efficiently.
