Abstract
An absolute angular sensor of a steering system for vehicles, which includes a power supply for supplying power, a pulse supply for generating pulses, a linear variable displacement transducer operated by a pulse outputted from the pulse generator for sensing a variable displacement of a rotator disc mounted at a steering shaft when the steering shaft operates, and outputting a signal in proportion to the sensed rotation displacement, a demodulator for demodulating the outputted signal from the linear variable displacement transducer, a DC (Direct Current) amplifier for amplifying the rectified external displacement from the demodulator into a certain level, and a DC output part for providing a signal output amplified by the DC amplifier, whereby it is possible to sense an absolute position accurately and an absolute angle of the steering shaft accurately.
