摘要：Nowadays, every existed vehicle mostly are using the two wheel steering system to control the movement of the vehicle whether it is front wheel drive, rear wheel drive or all wheel drive. But due to the awareness of safety, four wheel steering vehicles are being used increasingly due to high performance and stability that they bring to the vehicles. Already there are some commercial prototypes of such 4Wheel steering system, steer by wire systems and there’s a lot of research, both academic and commercial in the field. The upgradations in this turf are exceedingly expected and favorable. For our engineering major project at Madhav Institute of Technology and Science, we chose to prepare a prototype to adapt a few new ideas in this field. We named this model as Intelligent Dual Axle Steering System (I-DAS). In this report, the performance of four wheels steered vehicle model is considered which is optimally controlled during a lane change maneuver in three type of condition which is low speed maneuver, medium speed maneuver and high speed maneuver. For parking and low-speed maneuvers, the rear Wheel steer in the opposite direction of the front wheels, allowing much sharper turns. At higher speeds, the rear wheels steer in the same direction as the front wheels. This results in more stability and less body lean during fast lane changes and turns because the front wheels don’t have to drag non-steering rear wheels onto the path.
