Abstract
According to the requirements of the electrical power steering (EPS) system in the pure electric power bus, a recirculating-ball type EPS system was developed. A model for the recirculating-ball type EPS system of the pure electric power bus and a 2-DoF complete bus model were built. The concepts of steering such as the road feeling, the sensitivity, and the operation stability were introduced. The EPS system parameters were optimized by a genetic algorithm based on the principle of the constrained optimization of the multivariated function. The simulation results show that the optimization of the EPS system parameters improves effectively the road feeling and the operation stability of steering.
