Design, Modeling and Simulation of a Novel Omni-Directional Steering System

This paper presents a novel omni-directional steering system for electric vehicle. In order to guarantee the stability and the steerability of the electric vehicle, the proposed novel steering system consists of 2 conditional front wheel steering configuration and 4 wheel omni-directional independent steering configuration. The design of the 2 conditional front wheel steering configuration can guarantee the stability and the steerability of the vehicle. And the four wheel independent steering can achieve omni-directional motions such as zero radius turning (ZRT) and later parking (LP). This system was tested in simulation environment, and the last performance evaluation demonstrates the validity of the proposed omni-directional steering system.
