![]() Also a SBW should be considered as requirement for a DC motor actuator vehicle steer angle for operating at given desired reference value and a proper torque to boost undergoing for operating under different conditions. A microprocessor and interfacing circuits are designed to active control of DC motor. Necessary sensors and actuators replaced the conventional steering wheel. The test rig of SBW system showed a great benefit in modifying a conventional HPS system to be electronically SBW. The mathematical model has been used to evaluate the performance of SBW system by using Matlab/Simulink software package, a PID controller and Linear Quadratic Regulator (LQR) optimization techniques are employed to arrive at an optimal controller for the SBW to monitor the system dynamic behavior and stability characteristics. This paper aims to present an overview of the SBW with integrated hydraulic power steering (HPS) in commercial vehicle. ![]() ![]() The SBW is reproducing realistic steering feel, improving the vehicle returnability and it reduces the oscillatory effect of the steering system when the vehicle passes through an uneven road. ![]() With the continuous development of vehicle and electronic industry, Steering by Wire (SBW) is replacing the traditional steering device of vehicle. ![]()
