Abstract
In a cable-type steering device (in which a steering torque of a steering wheel is transmitted to wheels through a driven pulley, cables, and a follower pulley, and is assisted by a motor for a power-steering operation), a rotational angle of the driven pulley and a rotational angle of the follower pulley upon operation of the steering wheel are detected by potentiometers. A deviation between both of the rotational angles is proportional to an amount of elongation of the cables, i.e., the steering torque. Hence, an electronic control unit U controls the driving of the motor for the power-steering operation based on the deviation.
