TEMPERATURE CONTROL APPARATUS OF HEATING SEAT FOR AUTOMOBILE

摘要

PURPOSE: A temperature control device of a heating seat for a vehicle is provided to freely control temperature and heating values without a microcomputer. CONSTITUTION: A temperature control device of a heating seat for a vehicle comprises a periodic wave generator(110), a reference signal generator(120), a comparator(130), and a hot wire. The periodic wave generator generates periodic wave. The reference signal generator generates a uniform reference signal as time passes. If the difference of the reference signal and the periodic wave is the same as a pre-set value, the comparator generates an output signal of a designated size. The hot wire is installed in the heating seat to generate heat.
