Abstract

The newest technology of vehicle steering by wire (VSBW) system has made a significant improvement in vehicle safety dynamics, stability, comfort and maneuverability. The complete elimination of shaft that connect the steering wheel and the front wheel practically give problem to steering control specially in terms of directional control and wheel synchronization of the vehicle. The development of the VSBW Fuzzy PID control scheme that help to control the steering wheel and the front wheel. This Fuzzy PID is more like a hybrid type of controller that is PID controller and Fuzzy Logic controller are combine in one control scheme. The Fuzzy PID controller will control the steering angle and front wheel angle. The Fuzzy Logic controller will control the steering wheel angle where else the PID controller will control the front wheel angle. The Fuzzy PID controller used wheel tracking error to generate controlled steering angle. The learning method and manual tuning method is used to tuning the Fuzzy logic membership function. For PID controller, Ziegler Nichols method of tuning is being choose for these type of controller. There are two main parts in developing VSBW control scheme that is simulation section using Matlab/Simulink software and hardware section using Labview. The modelling of steering wheel and front wheel will be used to simulate in the Matlab/Simulink software. Actual steering with rack and pinion will be used for real-time experiment. The performance of control schemes is examined in term of input tracking capability, wheel synchronization and time response specifications. Finally, the result of the control schemes is presented and discussed
