This paper is focussed to assess the performance of a low cost steer-by-wire system developed in the Vehicle Dynamics Laboratory at Cranfield University. The steering system plays an important role in vehicle's safety by influencing its handling performance and therefore considered as a critical vehicle system. The performance of a steer-by-wire system is predominantly linked to its actuators' behaviour. This paper contains the findings of experiments carried out to measure the actuators' response. As the steering commands can be represented by step, sinusoidal and combination of such inputs therefore the actuators are subjected to similar sort of inputs with varying frequencies and amplitudes. In the later part a controller is developed to improve the performance of the steering system using the torque vectoring technique.
