Abstract: Conventional power steering systems use an engine accessory belt to drive the pump, providing pressurized fluid that operates a piston in the power steering gear or actuator to assist the driver. The aim of steer-by-wire technology is to completely do away with as many mechanical components as possible. Completely replacing conventional steering systems with steer-by-wire holds several advantages. In this paper we propose a steer-by-wire system modified with Field oriented control of motors. This system has two sections-Steering wheel section and Road wheel section. Two motors are used in each section for the torque required in a power steering. The control of these motors to turn the wheels of two sections is the main function of the microcontroller. Controlling methods used for motors are usually sinusoidal method and trapezoidal method but they have certain disadvantages. Therefore we have selected Field Oriented Control (FOC) for motor controlling which provides high efficiency, low noise, low torque ripple and good torque control over a wide speed range.
