1. A steering wheel-heating system comprising:
- an ambient sensor detecting temperature of external air;
an incar sensor detecting temperature of internal air of a vehicle;
a water temperature sensor detecting temperature of engine cooling water;
a temperature switch receiving FATC-set (Full Auto Temperature Control) temperature; and
a controller supplying or cutting power supplied to heating wires in a steering wheel on the basis of the temperature of the external air detected by the ambient sensor, the temperature of the internal air detected by the incar sensor, the temperature of the engine cooling water detected by the water temperature sensor, and the FATC-set temperature.

6. A method of heating a steering wheel in combination with a FATC (Full Auto Temperature Control) system, the method comprising:
-
a first step of comparing temperature of external air with critical external air temperature by a controller; a second step of comparing temperature of internal air with critical internal air temperature and temperature of cooling water with lower critical cooling water temperature, when the temperature of the external air is not higher than the critical external air temperature as a result of the first step; a third step of supplying power to heating wires in the steering wheel, when the temperature of the internal air is not higher than the critical internal air temperature and the temperature of the cooling water is not higher than the lower critical cooling water temperature as a result of the second step; and a fourth step of cutting power supplied to the heating wires in the steering wheel, when the temperature of the cooling water is higher than upper critical cooling water temperature and the difference between the temperature of the internal air and FATC-set temperature is less than a critic value, after the third step. - View Dependent Claims (9)
