Steering Torque Optimization of an In-wheel Motor Vehicle with Double Pivot Suspension Based on Response Surface and Genetic Algorithm

摘要

A rigid-elastic coupling multi-body dynamic model of an in-wheel motor vehicle with double pivot suspension was established. The steering effort performance is analyzed. Results showed an excessive steering force of the vehicle with double pivot suspension. By optimizing the suspension parameters using response surface surrogate model and genetic algorithm, the characteristic of steering effort was improved.
