Abstract
A steering system for a vehicle is provided in which each of the inner cables of two Bowden wires has one end thereof wound around and fixed to a driving pulley provided on a rotary shaft of a steering wheel, and the other end thereof is connected to a follower pulley. Spring sheets provided at end of outer tubes of the Bowden wires, are biased by springs and are connected to differential transformers. When a difference in tension corresponding to steering torque is generated between the two inner cables, the spring sheets are moved relative to each other, and a steering torque is determined based upon the amount of relative movement detected by the differential transformers. Thus, the steering torque inputted to the steering wheel can be correctly detected, while eliminating the influence of friction of the Bowden wires.
