Survey of 4ws Automotive Movement Fund with the Effects of Tire Stiffness (Published)

This paper proposes a 4WAS (4 Wheel Active Steer) system assists drivers by automatically controlling the steering angle of a vehicle’s four wheels according to speed. By controlling the steering angle of all four wheels, this active steering system helps improve stability and response at high speed and helps reduce driver’s steering workload at low speed. The study compared the operation of the system with and without PID controller. Computer simulations demonstrate good maneuverability of the proposed system.
